    What Can a 300-Watt Solar Generator Run?

    Solar Generators are an awesome option when you want to power your devices at home or outdoors. With a solar generator, you won’t have to worry about your devices running out of power as the power station offers an amazing backup solution. The fact that you can use solar energy to recharge it is another plus as solar is a clean source of energy available everywhere.

    But apart from charging your devices, what can a 300-watt solar generator power? We answer this question plus and give options to look into when picking a solar generator.

    What can a 300 Watt Solar Generator Run?

    First of all, you should understand that the 300 Watt is the inverter rating. This wattage represents the maximum draw you can get out of the battery pack via the DC-AC conversion from the inverter. Therefore this solar generator will not power anything above 300 watts. Also, any device application that is rated lower than 300 watts but has a higher surge watt (the initial power to start the device) will not work either.

    A 300-watt solar generator will charge your phone, tablet, and even drone. It will power your lights, mini-fan, and even a mini freezer for some time. However, it will not run a coffee maker, microwave, or even a small blender as these items have a high wattage. For that, you can go for a higher wattage generator like a 1000-watt generator

    How long will the solar generator run my devices and applications?

    Another important factor is the size of the battery pack itself. The size of the battery pack determines how much energy the solar generator has and consequently how long the solar generator will power your device.

    The solar generator should have a Wh (Watt-hour) rating. A watt-hour is a unit of energy used to measure the amount of work done or energy used over time. It is equal to one watt of power expended for one hour. For example, To run a 60W laptop for one hour you will need 60Wh.

    Most Solar generators however will match the inverter to the watt-hour rating. So a 200-watt solar generator will have a 200 Wh battery and a 300-watt solar generator will have a 300 Wh battery. This is so that it can provide power for at least an hour.

    300 Watt-hours can run various devices and applications. Assuming you are running a combination of different appliances then you run the following with the 300-watt solar generator:

    Application Wattage No of Hours Watt-Hours
    Light 10 Watt 5 hours 50 Wh
    Laptop 60 Watts 2 hours 120 Wh
    Phone (Fast Charger) 20 Watts 2 hours 40 Wh
    Mini Fan 30 Watts 3 hours 90 Wh

    But if you are planning to use one device then you can use your laptop for up to 5 hours and a mini fan for up to 9 hours. It can also charge your phone more than 20 times and your tablet more than 15 times. You can add a few hours of running time by using a 500-Watt Solar Generator.

    What type of Power do you get from the solar generator.

    Solar generators also have different output ports that include AC, DC, and USB. AC ports should provide power similar to a wall outlet and will have from an inverter that converts the DC power from the battery to AC power of 110V, which can be used to power household appliances. The DC output produces DC power at 12V for charging and for specialized appliances that require DC power. The USB output is where you charge your phone, tablet, or drone and has a 5v voltage.

    Other Components of a Solar Generator


    A 300-watt solar generator should be light enough to carry around. With a lithium-ion battery, it should not weigh more than 6 pounds and it should also include a handle so that it is easy to move around with.


    If it’s a small 200 – 300 watt solar generator it shouldn’t cost an arm and a leg. Your budget should be anywhere between 150 to 300.


    The generator should also have a well-lit LCD Display that gives information on the state of charge, voltage, and an indication of how much power is left or how far it is when charging.

    Lithium-ion Battery

    A lithium-ion battery is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.

    Lithium-ion batteries are common in consumer electronics. They are also used in electric vehicles and large storage applications.They have a higher energy density, which means they can store more energy than lead-acid batteries. This makes them a better choice for applications where weight and space are limited.

    Battery Management System

    A battery management system (BMS) is an electronic system that manages a battery pack’s state of charge, state of health, and thermal state while protecting the battery pack from over-charging and over-discharging. The BMS also monitors the pack’s temperature and voltage. The BMS is a critical part of any e-bike because it ensures the battery pack operates safely and reliably

    Charge Controller

    A charge controller is a device used to manage the charging of a battery bank from a solar array or other DC power source. The controller will limit the rate of charge to prevent damage to the batteries and also help to optimize the charging process to achieve the longest possible battery life.

    One of the main advantages of MPPT controllers is that they are more efficient than PWM controllers. They can extract more power from the solar panels, which means that they can charge the batteries more quickly. MPPT controllers can also handle a wider range of input voltages, which makes them suitable for

    Options when Charging a 300 Watt Solar Generator

    Solar generators can be charged in three ways depending on where you are and the circumstances; an AC outlet, a 12V/24V carport, or a Solar panel. To charge from a wall AC outlet should take around 5-6 hours and 6-7 hours from a carport or a 60W solar panel.

    Charging a 300 Watt Solar Generator from a Solar Panel

    As stated before to charge a 300-watt solar generator will need a 50-60 watt solar panel. This can be a lifesaver as you may not access power from the grid due to a blackout or you are out camping in the woods. This Solar Panel will charge the solar generator in around 6-7 hours depending on the sunlight availability. You may be tempted to increase the size but you can do so up to 100 watts for this solar generator as it cannot be exposed to a higher open voltage from a higher wattage solar panel.

    Which Power Station Is The Best For Your Needs? The Rockpals 300W Or 500W?

    The Rockpals 300W/280Wh (click to see latest version on Amazon) and 500W/540Wh (click to see the latest version on Amazon) are two popular power stations, also known as solar generators, from the same company.

    ecoflow, delta, 300w, solar, panel, bundle

    Both of them are portable, lightweight, and great portable batteries that can be brought camping or be used at home during power outages.

    But how do they compare, and which one is the best for your needs?

    Today we’re comparing the two to make the differences more clear than what the names tell us.

    If you’re interested in power stations for camping, you should check out my post on the best ones here.

    Let’s start by comparing the two on the table, then we’ll go through what the differences mean in practice.

    I’ll also share some of my solar panel recommendations for these power stations in case you want to be able to recharge the battery when away from home.

    Lastly, I’ll share some of the best alternative power stations to the Rockpals 300W and 500W made by other companies.

    Rockpals 300W Vs 500W – Specifications Compared

    Last update on 2023-06-29 / Affiliate links / Images from Amazon Product Advertising API

    Similarities Differences Explained

    Battery Capacity

    The battery capacity is exactly what it sounds like, how much battery power the power station can store at most.

    There is a big difference between the capacity of these two power stations, 280 versus 505 watt-hours.

    That’s a 93% increase, which means that the Rockpals 500W will power your devices for 93% longer.

    To understand what it means in everyday life, let’s imagine that we have a laptop with a 60W power brick.

    The Rockpals 300W power station will charge the laptop for almost four hours (280Wh/60W0.85=3.97 hours).

    The reason we multiply by 0.85 is to take the inverter efficiency into consideration.

    The Rockpals 500W power station will charge the same laptop for about 7.16 hours (505Wh/60W0.85=7.16 hours).

    A good way to know how much battery capacity you’re going to need is to make a list with every device you need to power/charge and for how long (in hours).

    A 60W device uses about 60 watt-hours per hour, so if you know the wattage of your chargers you can easily figure out how much capacity you’ll need.

    For example, a list of my devices would look like this.

    Device Watts Hours per day Total watt-hours required
    Laptop 60 3 180 (603)
    Phone 10 1 10 (101)
    Tablet 10 2 20 (102)
    Lights 10 4 40 (104)

    What the table tells us is that I am going to use 250 watt-hours a day based on my devices and hours of use.

    Since I am going to be using the inverter to power my devices, we also need to take the inverter efficiency into account.

    The inverter is about 85% efficient, so we’ll add that onto our total watt-hours: 2501.18=295 watt-hours.

    If you’re only going to be charging devices via USB or DC, the efficiency will be slightly higher, but I still recommend taking it into consideration when calculating.

    So I should choose a power station that has at least 295 watt-hours of battery capacity, which means that the Rockpals 300W wouldn’t quite be large enough for me.

    Remember that you can use the battery while it’s charging.

    One way to make the Rockpals 300W work for me would be to connect a solar panel that would recharge the battery during the day or at least replenish some of the battery power that I have used.

    This would only work if I was using the battery while the sun was out and didn’t use all of my devices at night.

    Inverter Rating

    The inverter in a power station changes the 12V DC battery power to 120V AC power and lets you use regular 120V devices via the AC outlet that looks like a household outlet.

    There is a difference between the two here as well since the Rockpals 300W has a 300W inverter and the 500W has a 500W inverter. That’s a 66% increase in power output.

    Well, if you have a 400W device, the 500W inverter will power it but not the 300W in the smaller power station since it exceeds the max output the inverter can handle.

    Or if you have 10 50W lights, you can power all of them with the Rockpals 500W (1050W=500W), while the Rockpals 300W can only power six of them (650W=300W).

    Whether you need the larger inverter or not depends on what you plan on powering and how many devices at the same time.

    Even though there is only one outlet on the smaller model, you can use a power strip to connect more than one 120V device.

    The Rockpals 500W has two outlets, but the 500W inverter rating is the total wattage they will output together, not separately.

    You might’ve noticed that the inverter rating has two numbers, a continuous watt and a surge watt.

    The surge watts is how much the inverter can output for a very short time, usually less than 30 seconds.

    When considering which power station to buy, you should ignore the surge watt rating and FOCUS on the continuous wattage which is what will matter the most in day-to-day use.

    As mentioned above, the Rockpals 500W has two AC outlets versus the single outlet on the 300W model.

    You can use a power strip with either of them to power several devices at once, but it’s convenient to have two on the larger model.

    There are 3 USB and a USB-C PD ports on both.

    The USB-C PD on both of the Rockpals power stations can input and output power.

    Which means you not only can charge your devices with it, you can also charge the battery in the power stations.

    The 300W USB-C is rated for 30 watts and the 500W is rated for 45 watts.

    ecoflow, delta, 300w, solar, panel, bundle

    Both models have a QC 3.0 port. Note that your device must support QC for it to utilize the faster charging. Other USB devices can still be used.

    There are five DC ports on both models. Both have a 12V cigarette port rated at 12V 8A but the 500W is the only one that has a regulated 12 volt outlet.

    Last but not least, the input port is different.

    The Rockpals 300W uses a less common 2 Pin port, while the 500W uses a 5.5×2.5mm port as an Anderson connector.

    It’s easier to find compatible solar panels for the 500W model since the connector is more common.

    The input ports are different, and the 500W can handle slightly more input watts when charging.

    The 500W model has a power brick that you must carry around, while the 300W model has the power management built-in and only requires the AC charging cable.

    It takes 6-7 hours to charge both via the included wall and car charger.

    The 500W model charges slightly faster with solar panels and can be fully charged in 6-7 hours with a 100W panel, while the 300W takes 8-9 hours with the same 100W panel.

    Both can also charge via the USB-C PD. 30 watts for the 300W version and 45 watts for the 500W version.

    Both of the Rockpals portable power station’s screens show the battery percentage, battery bars, time to empty/full, output watts, active ports, and temperature warnings.

    Size Weight

    There is a clear weight difference between the two, 7.7 versus 12.5 pounds.

    The larger model is also nearly twice as large in terms of total volume.

    Rockpals includes a wall charger, car charger, and MC4 to DC adapter with both models.

    No solar panels are included with either battery.

    Other Similarities Differences

    Both power stations use lithium batteries and MPPT charge controllers.

    They can both be used while charging and use a pure sine wave inverter.

    There are lights built into both on the front of the batteries that are turned on with a button (two buttons on the Rockpals 300W).

    On top of each, there is a built-in handle.

    Last but not least, both power stations have holes on the side for ventilation.

    Conclusion – Which Rockpals Power Station Is The Best For You?

    So we’ve made the differences and similarities clear between the two solar generators. Now you need to figure out what you need.

    Do you need the more portable and lightweight option that won’t run your devices as long?

    Or are you willing to lose some portability for an additional outlet that is more powerful overall and lasts almost twice as long?

    For my needs, the Rockpals 500W (click to view on Amazon) is the better power station due to the battery capacity on its own.

    At most, I only need to power my laptop, phone, tablet, Playstation 4, and TV.

    I would be fine with the 300W inverter on the smaller model, but being able to power my devices for almost twice as long before recharging the battery is worth it to me.

    If you only need to charge phones, tablets, CPAP machines, and lights, the Rockpals 300W (click to view on Amazon) will most likely be enough.

    But if you run a CPAP machine all night it might drain most of the battery and you would have to have a way to recharge the battery during the day.

    If you live in an RV, car or van and have a solar panel on top of your vehicle, the Rockpals 500W would be the more safe choice since you would have that extra battery capacity for cloudy days.

    You also wouldn’t have to rely on sunshine as much to recharge the smaller battery every day.

    Now, maybe you’ve come to the conclusion that not even the 500W is enough for you, then I recommend checking out the best alternative power stations down below.

    Solar Panel Recommendations

    Since both power stations include the MC4 to DC adapter, you have a lot of options when it comes to compatible solar panels.

    Rockpals makes panels that come in several sizes.

    The 60W (click to view on Amazon) and 100W (click to view on Amazon) are two popular portable options that are directly compatible with both.

    Two great panels that come with MC4 connectors are the Renogy 50W Eclipse solar panel and the Renogy 100W solar panel.

    Best Alternative Power Stations/Solar Generators

    Jackery makes great power stations with reliable inverters, regulated 12V outputs, common inputs, and a great display.

    Three models I recommend are the Explorer 240, Explorer 500, and Explorer 1000.

    The nrgGo 400 is another great option with two AC outlets, USB C PD, and a great display that shows the most relevant information.

    How we chose the best solar generators

    As an avid outdoorsman, I’ve had the opportunity to test an extremely wide range of outdoor gear, including mobile and off-grid electrification equipment like solar-powered generators, as well as inverter and dual-fuel generators. These became particularly essential when the pandemic forced my travels to become domestic rather than international, which prompted me to outfit a van for long-term road-tripping.

    To bring my work along for the ride, I needed a constant power source to charge my laptop, a portable fridge, lighting, and a myriad of devices and tools … even ebikes. As a result, I’ve tried all the leading portable power stations (and plenty that aren’t leading, too), so I know precisely what separates the best from the blah. I’ve written all about it (and other outdoor tech) for publications, including the Daily Beast, Thrillist, the Manual, and more. There were cases when my own opinion resulted in a tie, and I, therefore, looked to reviews from actual customers to determine which solar generators delivered the most satisfaction to the most users.

    The best solar generators: Reviews Recommendations

    The solar generators on this list span a wide range of budgets, from a few hundred dollars to a few thousand. They span several use cases, from camping to a backup for your home.

    Best high-capacity: Jackery Explorer 3000 Pro

    • Ample power storage for long trips or outages
    • Sturdy handles and wheels make it easy to move
    • Smooth design makes it easy to load and unload
    • High peak output for power-intensive tasks
    • Lots of ports for connectivity

    This is the big sibling to our best overall pick. Inside the Jackery Explorer 3000 Pro, you’ll find 3,024Wh of power storage, which is enough to power even large devices for extended periods of time. It can charge a high-end smartphone more than 100 times on a single charge. It can also power full-on appliances in an RV or emergency situation.

    Despite its large capacity, we learned firsthand that the Jackery Explorer 3000 Pro is relatively easy to move around. Sturdy handles molded into its case make it easy to pick up, while an extending handle and wheels make it easy to roll around at the campsite or any other location.

    It can charge in less than three hours from a standard outlet or, under optimal conditions with the 200W solar panels, it can fill up as quickly as eight hours. That full solar array can get large and unwieldy, but a smaller setup can still provide ample charging if you don’t need to max out the capacity daily.

    This portable power station offers the best of everything we loved about the Explorer 2000 Pro, there’s just more of it. When you’re living the van life, powering an RV, or trying to ride out a power outage, more is definitely better if you can justify the extra cost.

    Best for frequent use: Anker 767 Portable Power Station Solar Generator

    Why it made the cut: High capacity and fast charging make this long-lasting battery a solid everyday driver.

    • Charges up to 80% in less than two hours
    • Solid output and storage capacity
    • Optional battery pack doubles capacity
    • LiFePO4 batteries survive more charge cycles than traditional models
    • Plenty of ports
    • Built-in handle and wheels for transport

    Anker has equipped its massive portable power station with LiFePO4 batteries, which stand up much better to repeat charging and discharging over the long term than common lithium-ion cells. Anker claims it can charge and discharge up to 3,000 times before it reaches 80% battery health compared to 500 in a similar lithium-ion setup. While I haven’t had the chance to run it through 3,000 cycles, LiFePO4 batteries have a well-earned reputation for longevity.

    Regarding overall performance, the Anker 767 does everything you’d want a unit with these specs to do. The bad weather has given me [Executive Gear Editor Stan Horaczek] ample chances, unfortunately, to test it in real-world situations.

    The built-in battery offers a 2048Wh capacity and pumps out up to 2,400W. It does so through four standard AC outlets, an RV outlet, two 120W car outlets, two 12W USB-A ports, and three 100W USB-C ports.

    I used it during a blackout to keep our Wi-Fi running while charging my family’s devices. Filling a phone from zero barely makes a dent in the power station’s capacity, and it ran the router for several hours with plenty of juice left.

    In another instance, it powered our small meat freezer for four hours before the power came back on with some juice still left in the tank. It does what it promises.

    There are a few nice extra touches as well. Built-in wheels and an extendable handle allow it to roll like carry-on luggage. Unfortunately, those are necessary inclusions because it weighs a hefty 67.3 pounds. It’s manageable but definitely heavy compared to its competition.

    The Anker 767 is compatible with the company’s 200W solar panels, which fold up for easy transportation. I mostly charged the unit through my home’s AC power, a surprisingly quick process. The 767 Portable Power Station can go from flat to more than 80% charge in less than a half hour with sufficient power. It takes about two hours to get it fully juiced.

    Anker also offers a mobile app that connects to the power station via Bluetooth if you want to control it without actually going over and touching it.

    Best for camping: Goal Zero Yeti 1000 Core

    Buy it used or refurbished: eBay

    Why it made the cut: Thanks to its outstanding portability, high storage capacity, and Yeti’s famous durability, the Goal Zero Yeti 1000 Core is great for packing along for camping or van-living.

    Yeti is long-renowned for making some of the best outdoor gear money can buy, so when the company launched its Goal Zero line of solar generators, it was no surprise that they turned out to be awesome. While the whole line is great, the 1000 Core model’s balance between capacity and portability makes it perfect for taking on the road.

    While the 1000 Core has a third less capacity than our top pick, it charges up faster, making it a great option for Rapid solar replenishment. That said, its capacity is no slouch, offering 82 phone charges, 20 for a laptop, or upwards of 15 hours for a portable fridge (depending on wattage). Suffice it to say, that it’s more than capable of powering your basic camping gear.

    Beyond its charging capabilities, the Goal Zero 1000 Core excels at camping thanks to its hearty build quality. Built super tough—like pretty much everything Yeti makes—its exterior shell provides solid protection.

    The biggest issue it presents is the cost. Like pretty much everything Yeti produces, its price tag isn’t small. While there are other 1000-level solar generators for less, this one offers a great balance of power storage and portability.

    • Surprisingly affordable for what it offers

    You’ll be hard-pressed to find a solar generator better suited for living off the grid for an extended period than the Bluetti AC200 Max. It boasts a substantial 2,048Wh capacity, allowing you to power your whole life off it longer than most portable generators. Even better, you can daisy-chain multiple Bluetti batteries, expanding its capacity to a massive 8.192Wh. That’s flat-out enormous and translates into the ability to power a full-sized fridge for over a day or several hours of air conditioning. For the more modest needs of people who are used to living off a generator, it will last for a very long time.

    At the same time, the AC200 Max has an outstanding input capacity of 1,400W. That means you can plug in a pretty hefty array of solar panels to replenish its stores quickly. This allows you to keep your off-grid setup going with little to no interruption. It also features some specialty charging options, including a 30A plug, which lets you plug it directly into an RV, and multiple wireless charging pads for smaller devices.

    Best for homes: EcoFlow Delta Pro

    Why it made the cut: The EcoFlow Delta Pro delivers the standalone and expandable power capacity necessary to power your entire home.

    • Storage capacity: 3,600Wh standalone, expandable up to 25,000Wh
    • Input capacity: 6,500W
    • Output capacity: 3,600W (7,200W surge)

    If you’re looking for the best solar generator for home backup in the event of a power outage, the EcoFlow Delta Pro stands apart from the pack, thanks to an unrivaled power and output capacity. The Delta Pro alone packs a 3,600Wh wallop, and you can expand that to 25,000Wh by chaining it to extra EcoFlow batteries and generators. That’s a ton of power and it has the substantial output capacity necessary to power an entire house worth of electronics when you need it to.

    The Delta Pro also offers a companion app for iOS and Android that allows you to monitor energy usage, customize its operation, and monitor and manage a number of other elements.

    While it’s not overly large for what it does, the Delta Pro is a heavy piece of equipment. It has wheels, so it is technically portable, but this is meant to be put down in a home or other semi-permanent site. Given its size and power, it’s also a much more expensive device, especially if you’re springing for the add-ons. As the best solar power generator to provide backup power for your entire home, however, it’s worth every penny.

    Best portable: Anker 545

    Buy it used or refurbished: eBay

    Why it makes the cut: If you’re looking for highly portable power, the Anker 545 delivers.

    When portability is a priority, the Anker 545 offers the compact size and reduced weight you’re looking for and packs fairly substantial power to boot. Roughly the size of a shoebox and lighter than a case of beer, it’s easy to pack along with camping gear and move around without too much effort.

    To get something so light, though, you have to compromise on power. The Anker 545 has a capacity of 778Wh and an output capacity of 770W, which is plenty of power for keeping your devices charged. Specifically, that should provide about 55 phone charges, 10 for a laptop, or 38 for a camera. Unfortunately, the outlets only output at up to 500W, so it cannot power more demanding devices like hair dryers or electric stoves.

    That said, the Anker 545 has some bells and whistles, including an integrated flashlight and ambient light. All told it’s a solid option if you need a highly mobile generator.

    Best budget: Jackery Explorer 300

    Buy it used or refurbished: Amazon

    Why it made the cut: With its reasonable capacity, compact size, and solid build quality at a low price, the Jackery Explorer 300 is a great budget pick.

    Though it isn’t quite as impressive as our top picks for best overall and best high-capacity, Jackery’s smaller Explorer 300 solar generator is super compact and lightweight with a decent power capacity for its price. Less a mobile power station than an upscale power bank, the 7-pound Jackery Explorer 300 provides plenty of portable recharges for your devices when you’re camping, on a job site, driving, or just need some power and don’t have convenient access to an outlet. Its modest 293Wh capacity isn’t huge, but it’s enough to provide 31 phone charges, 15 for a camera, 6 for the average drone, 2.5 for a laptop, or a few hours of operation for a minifridge or TV. A built-in flashlight would have upped its camping game somewhat, but at 300 (and often considerably less if you catch it discounted), this highly portable little power station does a lot for a little.

    We tested this portable power station for several months, and it came in handy numerous times, especially during the winter when power outages abound. At one point, we had it powering two phones, a MacBook, and a small light.

    The built-in handle makes it very easy to lug around. It feels like carrying a lunch box. The screen is easy to read, and the whole package seems fairly durable. Our review unit hasn’t taken any dramatic tumbles yet, but it has gotten banged around in car trunks, duffle bags, and other less-than-luxurious accommodations with no issues. If you catch one of these on sale, get it and stick it in a cabinet. You’ll be extremely glad to have it around when the need arises.

    What to consider before buying the best solar generators

    Over the past few years, solar generators have exploded onto the market. There are now dozens of different brands that largely look more or less the same at a glance. The fact is there are only a few standouts amidst a sea of knockoffs. Here’s what to look for to ensure you’re getting a great one:

    How much power can it store?

    A portable solar generator comes in an extremely wide range of sizes, but a generator’s size doesn’t automatically make it capable of storing a lot of power. In fact, most are disappointingly limited and unable to store much more juice than a portable charger.

    To properly check a generator’s storage, you must look at its capacity, measured in watt-hours (Wh). One watt-hour is the equivalent of 1 watt flowing over the course of an hour. The best solar generators offer capacities of several hundred and sometimes several thousand watt-hours. That doesn’t mean, however, that it will provide power for several hundred or several thousand hours. Any generator will ultimately last a different amount of time, depending on what’s plugged into it.

    It’s easy to predict how long a generator will last when you use it to power one thing. For example, if you were to power a 100-watt bulb using a power station with a capacity of 500 watt-hours, it would stay lit for five continuous hours. Add a portable fridge that requires 50 watts per hour, your phone which uses 18, a mini-fan that uses three … you get the picture. The more capacity, the better.

    Charging capability

    No solar generator will hold a charge forever, so you want one capable of charging as quickly and easily as possible. This is where we put the “renewable” into “renewable energy.”

    All of the power stations included in this roundup can be charged by connecting them to solar panels (hence the designation “solar generators”). Still, you also want to look for the ability to charge via other sources like wall outlets and your vehicle’s 12-volt plug. This ensures that you can charge up whether you’re off-grid in the sun, plugged in while preparing at home, or using your dash socket on the go.

    You must also monitor a model’s charging input capacity, measured in watts (W). For example, a solar-powered generator with a max input of 100W can take in a continuous flow of up to 100 watts, which is about the minimum that you’ll reasonably want to look for. Most of the generators below have input capacities of at least a few hundred watts when charging via solar, so a few 50- to 200-watt solar panels will max them out.

    Output capability

    Solar generators need to keep the power coming in and going out. The best solar generators can simultaneously charge all your intended devices via whatever plugs are necessary.

    Any portable power station worth your money will have a high output capacity so you can charge many devices, even if they require a lot of juice. A generator’s maximum output should be much higher than its max input. While a particular model might only be capable of taking in a few hundred watts at any given moment, it will usually put out exponentially more. At a minimum, you’ll want a generator that can put out 300 watts at a time, though you’ll want at least 500 for larger tasks.

    The best solar generators should also offer a variety of output plugs, including AC outlets, USB-A, USB-C, and even 12-volt DC outlets like the one in your vehicle dash. This ensures you can charge several devices simultaneously regardless of their plug. The number of ports you’ll need will vary depending on how many devices you need to power, but it should have at least a couple of AC outlets and a few USB-A ports.


    While portable battery sources have been around for a while now, over the past several decades, they’ve been pretty heavy, unwieldy things. One of the most exciting aspects of the latest generation of solar generators is that they’ve become much more physically compact.

    Suppose you plan on taking a generator camping or working it into a van conversion where every square inch matters; well, size and weight become major considerations. All of the products we’ve recommended are about the size of one or two shoeboxes—three at the most. The lightest is about the weight of a 24-pack of soda, while the heaviest is 100 pounds. Most fall somewhere between 30-60 pounds.

    If you’re using your generator as a more or less stationary source of backup power at home, portability isn’t a huge issue. Still, we generally recommend keeping weight and size in mind; You never know when you’ll need it for something other than a backup. (Plus, who wants to lug around something heavy and awkward if they don’t have to?)

    Another consideration regarding portability involves the necessity for accessories, which can impact how easy it is to move and use your generator. Some generators, for example, require a lot of removable battery packs, which can be a hassle when you’re on the go or packing a vehicle. All of the inclusions on our list require some accessories—you can’t get solar power without connecting cables and solar panels—but they work well with minimal add-ons.


    As with any product you expect to last, durability and all-around quality craftsmanship are essential. This is especially true if you plan on lugging your generator around on camping and road trips. Many subpar power stations are made from cheap components and flimsy plastic that doesn’t feel like it will hold up under the rigors of the road.

    Durability isn’t something you can determine by reading a spec sheet off the internet. You’ve actually got to take the generator out, use it a bunch, and see how it holds up. I’ve verified the durability of these recommendations via a combination of my own actual field tests and reviews culled from countless real product owners.


    Q: What size solar generator should I get?

    It’s easy to underestimate how much capacity you need. A 1,000 watt-hours might sound like a lot, but if you’re going to power a converted van with a portable fridge, lights, and occasional phone and laptop top-off, that 1,000 watt-hours will go faster than you expect. I used a setup like this and know from personal experience that you should always overestimate how much power you’ll need.

    A generator with a capacity under 1,000Wh can keep electronics charged. A larger one with 1000-1500Wh should be the minimum for road trips where you’ll need it to last multiple days between full charges. For a house or worksite where you expect to use some serious energy—like a full-sized refrigerator or power tools—you’re going to want to start looking at the biggest possible power stations that can be daisy-chained to external batteries.

    If you want to get precise, there is an equation:

    Estimate how many hours you’ll need to power various devices. For example, if you want to power two light bulbs for 2 hours: you need 4 hours of operation.

    Add up the total wattage necessary: the two bulbs are 60 watts each, so you need 120 watts.

    Multiply these together to find the total watt-hours needed: 4 x 120 = 480. So, in this case you’d need at least a 500Wh solar generator.

    That might sound like a lot for two lightbulbs, but remember that, in most situations, you won’t really be powering 60-watt light bulbs for hours on end. You’ll be charging phones and laptops for an hour here or there, cooling a fridge that kicks on and off every once in a while, using power tools in short bursts, and whatnot.

    Q: How many years will a solar generator last?

    Most modern generators are rated to last upwards of 25 years. The best-designed power stations are pretty sturdy, with few to no moving parts, so they should likely keep kicking for a long time, provided that you care for them properly. I’ve been pretty rough with a few of mine, and they show no signs of stopping.

    Q: Can I run my house on solar power only?

    Yes and no. While it’s absolutely possible to power your house with solar power, you’re unlikely to do so with a portable solar generator unless you use several at once while limiting your power usage. The largest of our recommendations—the EcoFlow Delta Pro—will come fairly close when bolstered with extra batteries. If the power goes out, you’ll be able to keep your fridge cold and use basic electronics for a couple of days without recharging. With quality solar panels, good sunlight, and Smart energy usage, your power should theoretically go uninterrupted.

    Final thoughts on the best solar generators

    We’re living in a “golden age” for portable solar generators. When I was a kid, and my family was playing around with solar gear while camping in the ‘90s, the technology couldn’t charge many devices, so it wasn’t all that practical.

    ecoflow, delta, 300w, solar, panel, bundle

    By contrast, the solar generators we’ve recommended here are incredibly useful. I’ve relied on them to power my work and day-to-day needs while road-tripping nationwide. They’re also great when the power goes out. When a windstorm cut the power at my house for a couple of days, I was still working, watching my stories, and keeping the lights on.

    We haven’t even scratched the surface in terms of the potential offered by portable, reliable, renewable, relatively affordable power. What we can do now is already incredible. The potential for what may come next, though, is truly mind-blowing.
