    What is Affirm?

    Affirm is a financing alternative to credit cards and other credit-payment products. Affirm offers instant financing for online purchases to be paid in fixed monthly installments over 3, 6, or 12 months.

    Why buy with Affirm?

    • Buy and receive your purchase right away, and pay for it over several months. This payment option allows you to split the price of your purchase into fixed payment amounts that fit your monthly budget.
    • If Affirm approves your loan, you’ll see your loan terms before you make your purchase. See exactly how much you owe each month, the number of payments you must make, and the total amount of interest you’ll pay over the course of the loan. There are no hidden fees.
    • The application process is secure and real-time. Affirm asks you for a few pieces of information. After you provide this information, Affirm notifies you of the loan amount that you’re approved for, the interest rate, and the number of months that you have to pay off your loan.- all within seconds.
    • You don’t need a credit card to make a purchase. Affirm lends to the merchant directly on your behalf.
    • You may be eligible for Affirm financing even if you don’t have an extensive credit history. Affirm bases its loan decision not only on your credit score, but also on several other data points about you.
    • Affirm reminds you by email and SMS before your upcoming payment is due. Enable Autopay to schedule automatic monthly payments on your loan.

    What is required to have an Affirm account?

    To sign up for Affirm, you must:

    • Be 18 years or older (19 years or older in Alabama or if you’re a ward of the state in Nebraska).
    • Not be a resident of Iowa (IA) or West Virginia (WV).

    How does Affirm work?

    At checkout, choose Pay with Affirm.2. Affirm prompts you to enter a few pieces of information: Name, email, mobile phone number, date of birth, and the last four digits of your social security number. This information must be consistent and your own. 3. To ensure that you’re the person making the purchase, Affirm sends a text message to your cell phone with a unique authorization code.4. Enter the authorization code into the application form. Within a few seconds, Affirm notifies you of the loan amount you’re approved for, the interest rate, and the number of months you have to pay off your loan. You have the option to pay off your loan over three, six, or twelve months. Affirm states the amount of your fixed, monthly payments and the total amount of interest you’ll pay over the course of the loan.5. To accept Affirm’s financing offer, click Confirm Loan and you’re done.

    After your purchase, you’ll receive monthly email and SMS reminders about your upcoming payments. You can also set up autopay to avoid missing a payment. Your first monthly payment is due 30 days from the date that we (the merchant) processes your order.

    How does Affirm approve borrowers for loans?

    • Affirm asks for a few pieces of personal information: Name, email address, mobile phone number, date of birth, and the last four digits of your social security number.

    • Affirm bases its loan decision not only on your credit score, but also on several other data points. This means that you may be able to obtain financing from Affirm even if don’t have an extensive credit history.

    Does Affirm perform a credit check? Does it impact my credit score?

    Although Affirm performs a credit check when you apply for a loan, this won’t impact your credit score. However, if you’re approved and decide to buy with Affirm, your loan and payments may affect your credit score. Paying on time can help you build a positive credit history.

    Why was I denied financing by Affirm?

    The merchant has no information regarding a customer’s financing denial. Affirm strives to offer all credit-worthy applicants financing with Affirm, but isn’t able to offer credit in every case. Affirm will send you an email with more details about its decision. Unfortunately Affirm’s decision is final.

    Why was I asked to verify my identity?

    If Affirm has difficulty confirming your identity, you may need to provide more information. Affirm uses modern technology to confirm your identity, including verifying your address or full SSN, or requesting a photo of your ID. Affirm takes these steps in some cases to counter fraud and provide the most accurate credit decision they can.

    Why was I prompted to enter my income?

    Affirm may sometimes need more information about your finances and your ability to repay in order to make a credit decision. Your income gives Affirm additional insight into your ability to repay.

    Why was I prompted for my checking account?

    Affirm may sometimes need more information about your finances and your ability to repay in order to make a credit decision. If you are prompted to link your checking account and would like to proceed, please provide the login information for your online bank account. Affirm does not store your online login credentials-they are transmitted securely to your bank.

    If Affirm asks you to link your checking account, Affirm won’t be able to offer you credit if:

    • Your bank is not listed
    • You choose not to link your checking accountYou don’t use online bankingThe username and / or password you provide is incorrectYou’re unable to successfully connect your checking account

    Why is my bank not listed?

    Although Affirm is continually adding support for additional banks, they aren’t able to connect to every bank at the present time. We apologize for the inconvenience. If you’re unable to connect your bank, you’ll need to complete your purchase with another payment method.

    Why was I prompted for a down payment?

    ecoflow, delta, solar, generator, 160w, panel

    Affirm isn’t always able to offer credit for the full amount you request. In these cases, Affirm asks you to make a down payment with a debit card for the remainder of your purchase. The down payment amount can’t be changed and must be made upon confirming your loan and before the loan offer expires.

    Will I see how much interest I am paying prior to accepting my loan?

    Yes! Affirm works hard to be completely transparent. You’ll see the amount of interest you’ll owe on the terms page and again on the loan confirmation page. If you pay off your loan early, you’ll receive a rebate for any interest that hasn’t yet accrued.

    Why can’t customers outside the U.S. use Affirm?

    Affirm is available only to shoppers residing in the United States. Affirm hopes to expand its services to customers outside the U.S. in the future.

    What are Affirm’s fees?

    The annual percentage rate (APR) on an Affirm loan ranges from 10% to 30%. Affirm discloses any required fees upfront before you make a purchase, so you know exactly what you will pay for your financing. Affirm does not charge any hidden fees, including annual fees.

    Why is my Affirm interest rate so high?

    When Affirm determines your annual percentage rate (APR), it evaluates a number of factors, including your credit score and other data about you. If you finance future purchases with Affirm, you may be eligible for a lower APR depending on your financial situation at the time of purchase.

    This APR calculator will give you an idea of how much interest you actually pay:

    When you consider Affirm financing, carefully evaluate the loan terms that Affirm offers you and determine whether the monthly payments fit your budget.

    How is interest on an Affirm loan calculated?

    Affirm calculates the annual percentage rate (APR) of a loan using simple interest, which equals the rate multiplied by the loan amount and by the number of months the loan is outstanding.

    This model differs from compound interest, in which the interest expense is calculated on the loan amount and the accumulated interest on the loan from previous periods. Think about compound interest as interest on interest, which can increase the loan amount. Credit cards, for example, use compound interest to calculate the interest expense on outstanding credit card debt.

    Product Review: EcoFlow Brings Next-Level Power Size To RVers

    by Patrick Buchanan

    The Possibilities Are Endless With The All-Purpose EcoFlow DELTA Pro

    Just when I thought I had seen it all, our UPS driver (who now hates me) rolled up with this 99-lb behemoth, known as the EcoFlow DELTA Pro. Not only are the potential uses seemingly endless, but the EcoFlow DELTA Pro has more ways to charge back to full power than I have ever seen.

    If it isn’t obvious from the pictures, it will be from the specs provided later, but the EcoFlow DELTA Pro is not your standard “battery pack” to charge up your iPhone when camping. Sure, it will do that; in fact, if you could find a way to plug them all in somehow, it would charge over 700 phones. Obviously, that’s not a practical use case for an RVer, but seeing that 30-amp receptacle on the front of the unit should start to give you a sense of what this portable power station will do.

    That 30-amp plug on the EcoFlow

    There are a lot of things to talk about here, but let’s address that standard 30-amp plug on the front. Yes, you can plug your RV into the EcoFlow. Yes, it will power your camper, including the air conditioner. If your RV has AC softstarters installed, you should be able to run two air conditioners.

    Update (2023): SoftStartRV is now offering a Summer Special! Click the banner below for more details. Don’t miss out!

    Don’t need A/C right now? No problem. The EcoFlow Delta Pro has loads of power for dozens of other uses.

    Boondocking and off-grid

    One of the most obvious uses for the DELTA Pro is boondocking and off-grid camping. With this type of camping, you generally don’t need massive power all the time, but when you need it, you need it. Perhaps it’s to run the A/C to cool the camper down before bed. Maybe you simply need to top off the house batteries. A cloudy weekend might dictate your solar panels need a shot in the arm to help provide the power you need.

    In any case, having the reserve power of the EcoFlow available is both a comfort and a luxury. Imagine pairing the EcoFlow with something like the CarGenerator to potentially stay off-grid for weeks at a time.

    What does all that power mean?

    We’ve talked about some standard camping uses, but you may need some additional scale to put the full power of the EcoFlow Delta Pro in perspective. With the capacity available in the EcoFlow, you could run a standard 500w washing machine for 6.5 hours, keep a CPAP machine running for over 4 days, or recharge your laptop 57 times.

    Ready to blend your favorite mixer? You can do so for 6.5 hours, long after you’ve reached Margaritaville. The gamer in your family can run a PS5 for 16 straight hours, then charge it back up and man the electric grill for almost 3 hours to stave off the appetite they’ve built up.

    Power monitoring the EcoFlow

    You’ll be able to keep track of the power usage of your DELTA Pro on the unit itself or via the EcoFlow app. On the app, you can access your power settings, such as charging and discharging levels, AC charge speeds, controlling the Smart Generator, and more.

    Fast and versatile charging options

    The DELTA Pro offers nearly as many ways to charge as there are to use it. Of course, solar is a primary option. You can use solar energy to charge DELTA Pro in just 2.8-5.6 hours. DELTA Pro has a wide voltage range from 11-150V, which makes it compatible with 90% of third-party solar panels with solar connectors. And when the weather gets unpredictable, the Smart maximum power point tracking (MPPT) automatically adjusts, maximizing your solar generation at any time of the day.

    You’ll also get the standard A/C and D/C charging options found on any battery pack or solar generator. In fact, the DELTA Pro can be fully charged on standard AC in just 1.8 hours. Using their X-Stream technology, the EcoFlow charging is safe and managed to ensure long battery life.

    EV Charging

    What I found the most interesting, however, was the EV charging option. With the EcoFlow DELTA Pro, you can charge up at thousands of EV stations worldwide. This unique charging method gives you up to 3400W fast charging on the go.

    EcoFlow Home Smart Panel

    Seasonal or casual campers looking for more usage options and value to justify the cost might be interested in the EcoFlow Home Smart Panel. RVers looking for backup power at home might not have to look any further than EcoFlow.

    The EcoFlow Smart Home Panel is the heart of the DELTA Pro home battery ecosystem. It integrates multiple DELTA Pro units with 10 home circuits. Each DELTA Pro can be connected with extra batteries, solar panels, or Smart generators, giving you uninterrupted power during blackouts and Smart energy management for your critical loads.

    Battery technology efficiency

    DELTA Pro sports a brand-new LFP battery with 6,500 cycles, which means you can use DELTA Pro for years and years before your unit reaches 50% of the original capacity.

    EcoFlow’s battery management system provides real-time analysis and regulation of voltage, current, and temperature. This unique protection mechanism makes DELTA Pro an incredibly safe and efficient home battery.

    At 3,699, the EcoFlow DELTA Pro is an investment, and if you add the EcoFlow 400W solar kit, it quickly approaches 5K. However, it should also be considered as a serious alternative to retrofitting your existing RV with new batteries and solar power, which I contend could cost a great deal more than that.

    If you are in need of more power, alternative power, or backup power, check out the EcoFlow DELTA Pro and see if it’s right for you.

    EcoFlow DELTA Pro Power Station


    Shift In Innovation

    There had been a notable trend among the power station landscape over the past, few years that had perhaps been fueled by climate change, emergency preparation, looming threat of war, and the COVID-19 pandemic. Where manufacturers had focused on putting out “solar generators” — which really are just battery power stations that could be recharged with solar panels — with ever-increasing specifications that outdoor enthusiasts like me had been drooling over, I have been noticing a shift from the outdoors into the home. For instance, market leader Goal Zero has excellent batteries, solar panels, accessories, and integration kits, but many would be hard pressed to know that their products can also power an entire home or RV.

    Goal Zero Yeti 1500x 500x, Jackery Explorer 1000 300

    I have been observing friends and family thinking about having home solar panels installed to reduce their dependence on the local electric utility company, but short of purchasing a large battery from LG or Tesla Powerwall to store excess energy, they would still draw from the electric grid when the sun was not out at night. On the same note, a power outage would ironically also leave a solar-powered home without electricity. Those large LG/Tesla batteries are expensive, can only be installed by professionals, and may need to be replaced every ten years. So, what should you do? I would opt for a portable power station with a home integration kit from Goal Zero. Why? After the initial installation by a qualified electrician, you could modularly replace any end-of-life batteries yourself and even take the main Yeti power station unit camping. Flexibility!

    However, a boondocking friend of mine urged me to look at the high-capacity, modular EcoFlow Delta Pro (LiFePO4) battery. I did. And I was amazed by its feature set. I had also come across Jackery’s sister company, Geneverse (formerly Generark), who has the unique-looking HomePower Two (NCM) aimed at homes. Bluetti also has its EP500 (LiFePO4). All of that helped me realize an expanding market geared towards emergency preparation for the homeowner and/or recreational vehicle (RV) enthusiast. Good! Competition is great! Goal Zero, you have some work cut out for you there!

    Delta Pro: Front, Internal, Back /EcoFlow

    What are the differences? How do they compare to the Jackery Explorer 1000? I am a fan of both Goal Zero and Jackery as both bring their own advantages and disadvantages. Goal Zero and Jackery/Geneverse only had Lithium-ion Nickel Manganese Cobalt (NMC) battery offerings whereas Bluetti, EcoFlow, and BigBlue had Lithium-ion Lithium Iron Phosphate (LiFePO4 / LFP). The latter battery chemistry is less volatile (safer), more usable in extreme temperatures, and has a higher charge cycle count (battery lifetime). I will go over the differences towards the end of this article for those who want to know more.

    LiFePO4 batteries are less volatile (safer), more usable in extreme temperatures, and have a higher charge cycle count (battery lifetime) than NMC.

    I went for the EcoFlow Delta Pro Power Station and their 220W “Bifacial” Solar Panel (Review) for use with our vacation home merely because their feature sets looked so interesting. This two-part review will first go over the Delta Pro Battery and be followed by the 220W Bifacial Solar Panel.

    In A Nutshell

    The EcoFlow Delta Pro packs so many features and nuances, it took a surprisingly long time to summarize my thoughts for this review. It is one HECK of a beast of a power station! Although I was not able to test many of the capabilities due to my limited budget, reading and researching about some of the functions kept me in awe.

    EcoFlow 220W Bifacial Solar, Delta Pro

    Goal Zero had been the gold standard for a long time with its market leading quality, safety record, and philanthropy roots, but the Delta Pro definitely should put the company on notice with an ecosystem that surprisingly surpassed Goal Zero’s in many ways. Offering a 3,600Wh battery capacity that could be expanded to 25,000Wh nearly doubles what Goal Zero could currently offer at 15,671Wh, and its AC inverter leapfrogs Goal Zero’s 2,000W of continuous power and 3,500W surge with double that: 3,600W and 7,200W, respectively. What that translates to is more devices and appliances that can be left running for many more days than homes with the Tesla Powerwall or large LG batteries commonly paired with home solar panels.

    Sweet Spot: The 1000Wh battery capacity hits the sweet spot for many consumers, including this author, who are looking for the right balance of power and portability. But when it comes to home integration, the more Watt-hours a battery ecosystem offers, the longer one can power a home for during a blackout.

    Specifications and numbers aside, the Delta Pro has an impressive set of input (charging) options, including AC wall, EV charger (a first!), solar, DC-producing gas generator, and possibly a wind turbine in the near future. What wowed me was the Rapid charging capability when specific EcoFlow products are combined: 6,500W! Goal Zero’s best only charges at 600W, and two years ago, THAT number dropped my jaw. Charging a Delta Pro and Smart Extra Battery (7,200Wh) at 6,500W would take them from empty to full in less than 2 hours — SUPER impressive! Goal Zero’s 600W would have taken over 10 hours.

    What additionally sets the Delta Pro apart is its Double Voltage Hub that can double the capacity and output of various Delta Pro product combinations. Tack on the Solar Tracker that uses a top-mounted sensor to follow the sun for maximum exposure, a Smart Generator that uses gasoline to produce DC power to directly feed into the Delta Pro, and you have a good support system to maximize battery capacity to run appliances with for longer, if not infinite, time periods.

    A large, colorful display provides information about the battery’s status, and although it is beautiful, it lacks the details that Goal Zero’s higher-end products provide. EcoFlow makes up for that with its gorgeous smartphone app that also tracks historical data to help the owner make a variety of decisions from.

    I really like the telescoping, retractable handle built into the EcoFlow: extend it to one of two lengths to tilt the battery backwards, then pull and roll the 99-pound Delta Pro across the house — at least, that’s the theory. Dragging the heavy battery on uneven grounds (like gravel) or traversing stairs is a huge challenge with the Pro’s small wheels. Did you notice the weight I had just mentioned? Ninety-nine pounds is no joke for the average person to carry up a flight of stairs! Goal Zero’s Roll Cart, on the other hand, with its larger wheels conquer those obstacles and surfaces with much more ease.

    The EcoFlow tries to shed some of its LiFePO4 battery weight and cost by using a mostly plastic exterior. Although the Delta Pro still looks quite nice, Goal Zero’s Yeti X series is housed in a mostly metallic enclosure that helps dissipate heat and is more durable. Metal withstands impact force better than plastic, no doubt about that, but also adds weight. Two distinctive, exterior design philosophies each with their own pros and cons. Delta Pro is physically larger than the higher-capacity Yeti 6000X (6,071Wh), for some reason.

    EcoFlow Delta Pro vs Goal Zero Yeti 6000x

    What surprised me despite all the impressive features of the 3,600Wh Delta Pro, it still costs just a little more than the lower-capacity, 3,032Wh Goal Zero Yeti 3000x. That makes it a great value!

    Overall, it both pains and delights me to see the Delta Pro kicking Goal Zero’s Yeti X line to the curb. On one hand, Goal Zero now painfully looks a bit outdated, and on the other hand, Delta Pro has set a new bar that slaps Goal Zero in the face to wake up and innovate. Competition is always good for the consumer, and so, Goal Zero, what will you do next? EcoFlow has a winning product portfolio on its hands that is difficult to beat.


    As one of Time Magazine’s “Best Inventions of 2021” under the “Sustainability” category, EcoFlow’s Delta Pro power station deservedly turned some heads. It certainly caught my attention with its wide list of features, expansion options, and accessories primarily geared for home use. Market leader, Goal Zero, offers a similar range of products, but EcoFlow does so in a sleeker — and at times more innovative — package. The configuration options gave me some struggles to write about while researching the Delta Pro because there were so MANY, most of which I could not test because it would have cost over 30,400 to collect the entire ecosystem for the “full experience”! Perhaps EcoFlow could sponsor a few items to review someday? (Wink, wink)

    Bear with me! There is a LOT to discuss because of EcoFlow’s vast ecosystem of products. I will attempt to summarize the important ones and how they work with the Delta Pro.

    Delta Max vs Pro: The Max is a smaller, lighter version of the Pro with less capacity at 2,016 Wh, a smaller AC inverter, and no transport wheels.

    ecoflow, delta, solar, generator, 160w, panel

    Battery Capacity

    The Delta Pro offers 3,600 Watt-hours of battery capacity — how long something can run for — that can be expanded with up to two EcoFlow Smart Extra Batteries (3,600 Wh each) for a combined total of 10,800 Wh simply by connecting them with a pair of cables. That could power a typical home drawing 750-1,000W of power per hour for 10-12 hours. Double that to 21,600 Wh by linking another set of Delta Pro and 2 Extra Batteries via either the EcoFlow Smart Home Panel or the Double Voltage Hub. Finally, this can further be expanded to 25,000 Wh through the use of a Smart Home Panel, 2 Delta Pros, 2 Extra Batteries, and 2 EcoFlow Smart Generators — a gas-powered generator that produces virtually unlimited DC output (as long as gasoline is available) for more efficient charging of the Delta Pro.

    Goal Zero can only store up to 10,871 Wh with a Yeti 6000X and 4 Yeti Tank Expansion Batteries. Let that sink in. The market leader is actually BEHIND in this area.

    EcoFlow’s Smart Home Panel can power up to 10 electrical home circuits during a blackout, the Double Voltage Hub can double the Delta Pro’s capacity with the addition of another unit, and the Smart Generator can provide gas-generated DC power to the Delta Pro for more efficient charging. Furthermore, the generator can directly be controlled by the Delta Pro so it would only be started when needed.

    Power Output

    Another area the Delta Pro shines at is what devices — and how many of them — it can power at the same time. Its AC inverter can operate at a continuous 3,600W of energy and surge up to 7,200W. If those numbers do not make sense to you, do not worry. I will go over Continuous vs Peak (Surge) in more detail later.

    1648W Charging (Overloaded Cord Reel)

    You can throw a number of high-powered devices, like a home air conditioner, refrigerator, TV, laptop, and hair dryer at it with no problem whatsoever as long as their combined power usage does not exceed 3,600W. The Continuous output can be expanded to 4,500W with X-Boost, or 7,200W by combining 2 Delta Pros with either a Smart Home Panel or Double Voltage Hub.

    Goal Zero’s flagship Yeti 6000X can only go 2,000W continuously and peak at 3,500W — numbers that were impressive and unheard of when the product was announced in 2020.

    Note: Delta Pro will shut off its AC inverter if it detects the wall plug getting overloaded when used in pass-through (UPS) mode. Only the battery’s 30A outlet can output 3,600W when disconnected from the AC wall.

    Battery Technology

    Li-ion: LiFePO4 vs NMC

    There had been a lot of debate over whether Nickel Manganese Cobalt (NMC) or Lithium Iron Phosphate (LiFePO4) was better. Both are Lithium-ion batteries. Goal Zero, Jackery, and most of today’s power station manufacturers use NMC, but why do EcoFlow and Bluetti use LiFePO4 when they are bulkier and heavier? There are important distinctions, but the best battery is the one that meets all or most of your unique needs.

    Charge Cycles

    One of the most significant differences — and buying factors — is the charge cycle count for both battery chemistries. It measures how long the battery can be used for before it must be replaced or thrown away. LiFePO4’s count is 1,500-2,000, whereas NMC is 500. However, both have a useful life that can range between 3,000 – 5,000 cycles (even as much as 7,000 with proper care). But how does the count determine longevity?

    Delta Pro: Front, Internal, Back /EcoFlow

    Let’s look at Li-ion NMC as an example. It loses about 20-25% of total capacity after every 500 charge cycle. That means after the first 500 cycles, the battery drops 20% from when it was new, then another 20% after the next 500 cycles, and 20% again after that one. It would take roughly 1,500 charging cycles to have the battery last only half as long as when it was brand-new. Thus, it should be usable for 2,000 cycles or about 6-10 years. Li-ion LiFePO4 can last longer.

    CAUTION: Lithium-ion (LiFePO4 and NMC) batteries do NOT like to remain discharged at 0% for prolonged periods of time. If you let your battery stay at 0% for too long, you may not be able to charge it again without specialized equipment. Keep them at between 20-80% while in storage to maximize their lifetime.

    LiFePO4 Advantages

    • Safer, less volatile, and thus cheaper to manufacture
    • Higher charge cycle: 1500-2000 (10 years). NMC: 500 (6-10 years)
    • Usable in more extreme temperatures (-4F/-20C to 176F/80C). NMC: only 140F/60C max
    • Holds 350-day charge. NMC: 300

    Input (Charging) Options

    Get yourself some popcorn for this. There are over a handful of ways to charge the Delta Pro, one of which provides 6,500W of input and prompted EcoFlow to claim the “World’s Fastest Charging” power station title.

    • AC
    • Wall: 1,800W (120V @ 15A) or 3,000W (240V @ 12.5A)
    • No power brick — 14AWG cord plugs directly from the wall to the battery
    • Never, ever use an extension cord to charge with! It could cause a fire or trip the circuit breaker at best
    • Charge to 100% at level 2 AC EV charging stations (with Type 1 J1772 or Type 2 Mennekes connector types) in 1.7 hours, according to the manufacturer
    • Provides up to 10 home circuits with power within 20ms of a blackout
    • Solar (XT60 port): 1,600W (11-150V @ 15A)
    • Uses MPPT that is much more efficient for charging than the older PWM technology
    • Any combination of most solar panel brands and number of panels can be used as long as their combined voltage and current do not exceed 11-150V and 15A
    • Connect up to 3 in series — or 2 sets of 3 (in series) for a total of 6 in parallel. Keep open-circuit voltage at 10-65V

    Smart Extra Battery, Smart Generator, Solar Tracker, Remote Control /EcoFlow

    • EcoFlow Smart Generator (Gas): 1,800W (up to 5,400Wh on a full tank)
    • Generator can be used standalone or with Delta Pro with included Smart Generator Adapter
    • I had asked Goal Zero and Jackery for this option for years!

    Tip: A record-breaking input of 6,500W (!) can be achieved by combining AC Solar Smart Generator charging! (A Smart Extra Battery must be connected to the Delta Pro for this to work.)

    AC Charging Speeds

    The back of the Delta Pro has a toggle for how much power it should draw for charging: Fast or Slow/Custom.

    • Fast: 1,800W (120V @ 15A) or 3,000W (240V @ 12.5A)
    • 0-80% in 2 hours and to 100% after another 45 mins
    • Slow charging is gentler on the battery, prolongs its lifetime, and minimizes risk of tripping the circuit breaker
    • Custom allows the Delta to charge at a configured rate so the wall circuit would not be overloaded. That’s an EXCELLENT feature to have!
    • Example: If an AC Circuit can only handle 1,200W and a coffee maker uses 800W, then the Delta Pro should be configured to charge at no more than 400W (1,200W – 800W)

    Tip: AC charging is prioritized over DC when both are connected simultaneously. Never use an extension cord to charge the Delta Pro with unless it’s a heavy-duty one.

    EcoFlow Delta Pro Carry Handles

    Output Options

    • (4) 20A
    • (1) NEMA 30A for RV hookup (3 prongs = 30A, 4 prongs = 50A)

    If the Delta Pro is used in pass-through UPS (uninterruptible power supply) mode, the internal circuit will turn off its inverter if it detects the AC wall outlet getting overloaded (ie. passing through more than 20A). This means that it could shut off at 1,200W without ever reaching its 3,600W capacity. To use the full 3,600W, disconnect it from the wall and let the battery provide that power.

    Note: Using a battery as a UPS (charging and outputting at the same time) could shorten its lifetime.

    • DC
    • (2) USB-A (12W max, 5V @ 2.4A)
    • (2) USB-A Fast Charge (18W max)
    • (2) USB-C (100W max, 5/9/12/15/20V @ 5A)
    • Could charge two high-powered laptops at the same time
    • A common use for this port is to connect a DC5521-to-Car Cigarette Port adapter so another car freezer, for example, could be connected
    • Anderson Power Pole (APP) port (378W max, 12.6V @ 30A)
    • Vertically configured like Goal Zero’s HPP, but in reverse
    • Connect an EcoFlow Remote Control unit via an Ethernet network cable for monitoring and controlling the Delta Pro from afar. This allows the battery to be tucked away from view

    Portable Air Conditioner

    The EcoFlow Wave is a portable air conditioner that accepts both AC and DC input. The company, of course, recommends using its own Delta power stations for better efficiency and longer runtime because they can draw directly from DC power. In a pinch, any battery or generator capable of providing the Wave-required input wattage could be used, but keep in mind that AC power loses some energy due to conversion to DC.


    • Superfast, configurable charging speeds (200W – 1,800W or up to 6,500W under specific conditions!)
    • Up to 2,000 – 3,000 cycles based on my research (I do not believe EcoFlow’s claim of lasting much longer than 6,500 cycles. Hope they prove me wrong 15-20 years from now!)
    • Much safer and stable than Li-ion NMC
    • Enough to power a typical home for days — or, when used with the EcoFlow (Gas) Smart Generator and/or set of solar panels, virtually forever
    • Pure-Sine Wave AC Inverter
    • Clean power for sensitive electronics
    • Less heat
    • Note: Some manufacturers claim to be Pure-Sine when they are actually Modified or Square Waves

    Wheels, Retractable Carry Handle

    ecoflow, delta, solar, generator, 160w, panel
    • High-quality BMS (Battery Management System) for safety
    • Provides built-in overload, overcharge (automatic stop when the device is full), and short-circuit protection

    Tip: It is possible to get multiple companies’ products (battery power stations and solar panels) to work with one another once you understand the different connector types, such as Anderson APP, MC4, 8mm, and so on. In one test, I had simultaneously connected solar panels by Goal Zero, Jackery, Suaoki, and Paxcess to the Yeti 1500x’s Anderson port to collect energy from all four! Although I did not test this with the Delta Pro, it should work the same way.

    • Impressive input and output options, including a NEMA 30A for RV hookup
    • Up to 1,600W of solar charging
    • Competition hopefully continues to spur better products from all companies


    • Weight is due to the use of 3,600Wh of LiFePO4 battery cells instead of NMC
    • Comparison: Goal Zero, despite using a more heavy-duty, metallic enclosure, has the Yeti 3000X (3,032Wh) weigh at 70lbs, Yeti 6000X (6,071Wh) at 106 lbs
    • Even bulkier than Goal Zero’s Yeti 6000x (15.3″ x 10.1″ x 17″) that has 67% more battery capacity. Yeti 3000x is 15.3″ x 10.2″ x 13.6″
    • Cable to link Delta Pro with additional Smart Batteries is too short, limiting how and where the batteries can be placed
    • Car Cigarette Port only accepts 96W of input at 12V
    • Goal Zero Yeti X and Jackery Explorer series can take 120W (12V @ 10A)
    • Leads to landfill/environmental waste. Please recycle responsibly!
    • Most companies arrange APP horizontally
    • Can be remediated by buying an APP extension cable, such as those by iGreely, and re-arranging it


    • Without anything plugged in, the AC inverter still draws 7W on its own
    • Or, according to some companies, including Goal Zero, keep it plugged in when not in use and discharge it to 50% every 3-4 months
    • The charging controller automatically gets disabled once the battery is full
    • You may also charge it to 80% for storage, but be sure to discharge to 20% every 3-4 months
    • There is no “memory effect” in this station’s battery
    • Note: It is better to NOT let it completely drain before recharging
    • Could take 1-1.5 years to go from full to empty

    CAUTION: Lithium-ion (LiFePO4 and NMC) batteries do NOT like to remain discharged at 0% for prolonged periods of time. If you let your battery stay at 0% for too long, you may not be able to charge it again without specialized equipment.

    Continuous vs Peak Output

    Goal Zero Yeti 500x: 300W (1,200W Peak)

    It is important to understand the difference between Watts and Watt-Hours. How much power is used or produced is measured in Watts, and how much energy a battery can store is calculated in Watt-Hours. See the “Calculations” section below for more details.

    How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts).

    • AC Inverter: Converts battery (DC) power into AC
    • Delta Pro provides 3,600W continuous output with a 7,200W peak
    • Turns on OK (PEAK under 2,400W):
    • Freezer starts at 400W (peak), runs at 150W once on
    • Coffee maker starts at 1,400W (peak), runs at 800W once on
    • Home AC starts at 4,000W (peak), runs at 1,000W once on

    Most devices power on at a higher (Peak) wattage than when they are already on (Continuous). Therefore, if its peak exceeds the power station’s max, it may not be able to start

    • Continuous Output (Running): Once devices are on, as long as they keep drawing less than 3,600W total, they will stay ON until the battery runs out
    • CONTINUES running (under 3,600W)
    • 100W TV 60W laptop = 160W
    • Temporary overdrawing beyond 3,600W for a few seconds is okay. A quality BMS will protectively shut down the battery if the surge does not end after a while. Regularly going over for a prolonged time can ruin the battery in the long run
    • 300W appliance (500W peak) 1,000W Home AC (4,000W peak) 800W Coffee maker (1,400W peak) 1,200W Miter saw (2,400W peak) 400W appliance = 3,700W. Probably will stay on for a short period
    • Add 1,000W mower (1,400W peak) = 4,700W. Battery will definitely shut down

    Solar Panel – Warning

    EcoFlow 220W Bifacial Solar, Delta Pro

    This power station can be charged with one or more solar panels. There are SOME PRECAUTIONS you must take to minimize battery damage and/or injury to life/property:

    • Never exceed the maximum Voltage (V) or Amperage (A) of the power station’s charging port
    • Delta Pro limits input to 15A [Thank you, Billy Tanglewood and Kevin Lauzon for the clarification]

    Wondering what size solar panel to get? See the “Calculations” section below.

    Calculations – Size Time

    What size battery should you get? How long will it power your fridge for? How long will it take to recharge? The below calculations can help answer those questions and are rough ESTIMATES as conditions, battery quality, and age can vary.

    Time to Charge Battery

    • Calc: Hours to charge battery = Battery capacity (Wh) / Input Wattage
    • Note: As battery approaches 75% full, the input charge will increasingly be slowed down to prevent overcharging

    Charge Time with Solar

    • Calc: Hours to charge battery = Battery capacity (Wh) / (Panel Wattage x [0.5 or 0.75])
    • In a perfect lab environment, solar panels charge at the listed wattage
    • Expect to only receive 50-75% on a good, sunny day (ie. 75W – 113W for a 150W panel), depending on panel’s age, component quality, and weather
    • Keep charging even when overcast as the panels will STILL collect energy
    • Underproduction: If a 200W panel is not making enough (ie. only 50W) due to bad conditions, adding extra ones (ie. two more 200W) can generate a higher, combined output (ie. 50W 110W from the two panels = 160W total)
    • Overproduction: If the panels make more (ie. 400W) than the maximum the power station charge port can take (ie. 120W), only the max (ie. 120W) will go through

    Watts Used/Produced

    • Calc: Watts used or produced by device = Voltage x Amperage
    • Vacuum with 120V @ 9.5A uses 1,140W
    • Solar panel with 12V @ 10A can produce up to 120W

    Ideal Battery Size

    • Calc: Battery capacity (Wh) = Watts used by device x Hours needed for / 0.85
    • 10-15% of power is lost during power conversion

    How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts).

    Time Before Battery is Empty

    • Calc: Hours available for device = Battery capacity (Wh) x 0.85 / Watts used by device
    • 10-15% of power is lost during power conversion

    Time to Charge Device

    • Calc: Hours to charge device = Device’s battery capacity (Wh) / Input Wattage
    • 60W laptop with 200Wh battery: Up to 3.4 hrs (200 Wh / 60W)

    Conversion to mAh

    • Calc: Powerbank-equivalent capacity (mAh) = Battery capacity (Wh) / Voltage x 1000
    • 1 Ah = 1000 mAh

    Tips and Suggestions


    • Always test your devices with the power station before you depend on it on the go
    • Unlike NMC that is volatile, LiFePO4 (which the Delta Pro uses) is one of the safest battery technologies available today. Nonetheless…
    • To minimize fire damage to your belongings or loved ones, store the power station in the garage and not inside the house. Best storage is a dry, cool place
    • You cannot bring a battery of this capacity on a plane
    • Keep the battery out of direct sunlight. I usually store it on the floor of the car and crack open the Windows a tiny bit
    • Do not USE any power station in a tightly enclosed area as it can overheat
    • Do not USE in the car if temperatures fall below or exceed the battery’s rated, operating temperature

    Jump Start Car?

    A battery power station like this one cannot be used to jump start a car. Instead, I suggest getting a small, portable one specifically made for that, such as my favorite: NOCO Genius Boost Car Jump Starter (Lithium Battery).

    Use With Other Brands

    Nearly all of the leading power station manufacturers can be used with competing products or accessories — solar panels in particular.

    As long as the panels or different Watt-capacities produce the same VOLTAGE, you will be able to safely use them with the EcoFlow Delta Pro. However, be sure to NOT exceed the power station’s rated input Voltage or Amperage! All you would generally need to interconnect is to buy adapter cables that convert from MC4, 8mm, or other connector types to the Delta Pro’s APP port.

    I had previously tested my Goal Zero Yeti 1500x with the company’s own Nomad panel and those by Jackery, Paxcess, and Suaoki. It was a bliss in interconnectivity! What that means is that you can buy lower-priced solar panels that may produce the same capacity as those made by the power station’s manufacturer. You do not always have to buy their own branded products as long as the substitutes stay within the rated limits.

    Final Thoughts

    Delta Pro Package /EcoFlow

    Wow, just wow! I am so glad that my boondocking/RV friends recommended me to check out EcoFlow batteries for our vacation home. The Delta Pro opened my eyes and dropped my jaw a number of times during my research with an impressive set of features, capacities, capabilities, and integration options that rival and surpass industry leaders like Goal Zero, Jackery, and Bluetti! The list was so extensive, it took me far too long to try and collect my thoughts and research for this article.

    The Delta Pro will hopefully kick the competition in the rear, and force them to innovate and surpass EcoFlow’s latest products with their own. Competition is always good for the consumer, and I cannot wait to see what my favorite companies, Goal Zero and Jackery (and sister company, Geneverse), have cooked up in response!

    Power Station Comparison

    Check it out! Ultimate Reference: Power Station Comparison – We summarized the specifications of many of the power stations we had come across or reviewed all in one place.

    Gas/Propane Generators vs Battery Power Stations

    In July 2020, I wrote about this topic after many asked what their differences were. In short, gas/propane generators can run virtually forever but are loud, dirty, and potentially quite dangerous. Battery power stations, on the other hand, are more portable, silent, less volatile, and can be operated indoor, but depend on external power (like solar) to recharge. Where gas/propane are used to GENERATE electricity, batteries STORE them for later use. Personally, I am a fan of the latter because they are so easy to carry around and are safer to use.

    Who is EcoFlow (EF)?

    EF Delta 2 and Wave (with battery)

    EcoFlow was formed in 2017, ten years after Goal Zero had its start. Four years later saw the launch of the Delta Pro series in 2021 that garnered so much widespread attention, it earned one of Time Magazine’s “Best Inventions of 2021” under the “Sustainability” category.

    A friend of mine once said that Goal Zero is “the best of the best” because of one simple reason: their vast ecosystem. I did not understand at the time what he meant, but as I learned more about the Yeti 1500x, my eyes were opened. Then EcoFlow came along with the Delta Pro that not only matched, but managed to surpass Goal Zero in many ways with its own collection of products.

    Battery Technology and Safety

    Goal Zero debuted with Lead-Acid batteries that were bulky and heavy. Today’s devices use Lithium-ion — commonly Nickel Manganese Cobalt (NCM) or Lithium Iron Phosphate (LiFePO4 / LFP) chemistries — for more power in a smaller, lighter package. NMC, however, is more volatile than LiFePO4 and becomes riskier as more cells are packed together. Goal Zero and Jackery use NMC whereas EcoFlow and Bluetti use LiFePO4.

    • How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts)
    • The higher the Watt-hour (Wh) capacity rating, the more dangerous the battery could become if not handled right

    The quality of the battery cells and the BMS (Battery Management System) are crucial for safety.

    Cell Manufacturers

    Battery cells made by LG and Sony are among the best in the hobbyist world as are Sanyo/Panasonic and Samsung. Goal Zero uses LG. Jackery also uses LG or BAK (a leading Chinese brand). EcoFlow makes its own. During my years of research, I found that use of lower-quality batteries could pose a serious risk to life and property and should become a crucial part in deciding what to buy.


    The second part in a battery’s safe operation depends heavily on the design and BMS (Battery Management System). Some BMS manufacturers, unfortunately, overstate their capabilities that could lead to catastrophic failure.

    • Design should allow for proper, thermal cooling, use quality components, and obtain proper certifications
    • Batteries made by known manufacturers are less likely to fail
    • BMS should sufficiently restrict the battery from going past its capabilities
