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. Only you know all the factors that make one of these the best solar generator for you, but we think that one of these will get the job done.

Best overall: Jackery Explorer 2000 Pro

Buy it used or refurbished: eBay

Why it made the cut: This Jackery solar generator delivers the best blend of capacity, input/output capability, portability, and durability.

• Storage capacity: 2,160Wh
• Input capacity: 1,200W
• Output capacity: 2,200W (4,400W surge)
• Dimensions: 15.1 x 10.5 x 12.1 inches
• Weight: 43 lbs
• Price: 2,498
• Fast charging and outstanding capacity
• Durable and easy to use
• Plenty of ports
• Can connect to six 200W solar panels

The biggest portable power station from Jackery, a leading solar generator manufacturer, the Explorer 2000 Pro offers a tremendous 2,160 watt-hours of power, making it capable of charging a full camping setup for a few days. When plugged into six 200W solar panels, an upgrade over the four-panel setup available on the Jackery Explorer 1500, you can fully charge this portable power station in just 2-2.5 hours. That’s less than half the time of the smaller model.

On top of all that, it’s extremely user-friendly. Numerous output ports ensure that you can plug in a wide range of devices and electrical equipment. Its functions are highly intuitive, and the digital display is easy to understand. Like other Jackery generators, it’s incredibly durable, too. The one potential downside is its weight: At 43 pounds, it’s a bit heavy for its size. Even so, for all the power you can store, and the Rapid-charging time, the Jackery Explorer 2000 Pro will keep the lights on wherever you need power.

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.

• Storage capacity: 983Wh
• Input capacity: 600W
• Output capacity: 1,200W (2,400W surge)
• Dimensions: 9.86 x 15.25 x 10.23 inches
• Weight: 31.68 lbs
• Price: 1,198.95
• Highly portable
• Incredible durability
• Rapid recharge rate
• Plenty of plugs

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.

Best for off-grid living: Bluetti AC200 Max

Buy it used or refurbished: eBay

Why it made the cut: Thanks to its high solo capacity and ability to daisy-chain with additional batteries, the Bluetti AC200 Max is perfect for bringing power off the grid.

• Storage capacity: 2,048Wh standalone, expandable up to 8,192Wh
• Input capacity: 1,400W
• Output capacity: 2,200W (4,800W surge)
• Dimensions: 16.5 x 11 x 15.2 inches
• Weight: 61.9 lbs
• Price: 1,999
• Massive capacity
• Daisy-chain capability
• Lightning-fast input capacity
• 30A RV plug and two wireless charging pads
• 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)
• Dimensions: 25 x 11.2 x 16.4 inches
• Weight: 99 lbs
• Price: 3,699
• Enormous capacity
• Daisy-chain capability
• 30A RV plug
• Lightning-fast input capacity
• Wi-Fi and Smartphone connectivity

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.

Portability

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.

Durability

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.

FAQs

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.

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.

Jackery Solar Generator 1500 Pro Review: Power To The People

The Jackery booth at the Consumer Electronics Show was attention-grabbing, with solar panels and battery power systems laid out in various outdoor dioramas. Each setup was designed to highlight Jackery’s Portable Power System and its Solar Generator line.

A Jeep topped with solar panels and a glistening silver Airstream brought back memories of my camping trips to mountain bike and how I could have used a zero-emission power supply to recharge devices.

Even before COVID, people worked remotely, using technology to get work done from anywhere. Several of the creators I know had already begun living and working in converted Sprinter vans and other vehicles, and COVID only increased the scope of remote work acceptance.

Sure, you can power your gear off your vehicle’s battery, but then you need to run the engine to recharge the battery, which is a non-eco-friendly system.

But YouTubers living in a van down by the river aren’t the only ones that can benefit from a sustainable power supply. I have assisted on many commercial shoots that used gas-powered generators to recharge batteries and power some lights. A solar-based power system would have been better for the environment but easier to use, eliminating the need to carry gasoline or diesel, and could operate entirely silently.

For wedding photographers and videographers, wildlife and landscape photographers, sports shooters, and anyone else who needs to work far from an outlet, a solar-driven power system is an expense that will pay for itself immediately.

Design and Build Quality

Jackery started selling solar panels and battery backup systems nine years ago, and it has since sold more than two million units (according to its public sales data.) The lineup has grown to include nine power stations (the battery system by itself) of various capacities and nine configurations of Solar Generators, which is a power station plus one of the solar panels.

I tested the Jackery Solar Generator 1500 Pro, a combination of its 1500W power system, the Explorer 1500 Pro, and a 200W solar panel. The solar panels can be daisy-chained, providing additional input power. When access is available to a power supply, the unit can be plugged in and recharged via AC power.

All of Jackery’s systems feature fast charging and the 1500 Pro charges from empty to full in under 10 hours from the 200W SolarSaga panel alone. Of course, this charging speed requires a fully-sunny day (and 10 hours of sun at that), but that’s still an incredibly short recharge period.

The SolarSaga panels are segmented and can be arrayed in several ways to maximize access to the sun best. A single weather-proof cable connects to the SolarSaga and plugs into the back of the Jackery Explorer Pro 1500 Pro. The rear also has a jack for AC power input.

The 1500 Pro weighs just under 38 pounds, but the attached carry handle makes it feel lighter since it’s unnecessary to grab it by the bottom and hold it in front of you. Jackery claims this unit is 20% lighter than competing systems with the same capacity.

Much of the portability comes down to size. The Jackery Explorer Pro 1500 Pro is only 15.2 inches wide, 10.58 inches deep, and 12.11 inches tall. Back in the 1980s, I had a boom box that was bigger than this.

The front of the unit has an impressive selection of power jacks. There are Dual PD100W jacks, three 1800W AC outlets, two USB-C charging ports, and a 12V car “cigarette lighter” jack.

There’s also a very bright LED light set into the face of the unit, which was helpful but tended to point at my eyes in the dark since it’s on the front of the device.

During the testing of the unit, we had an unexpected blackout, so we had a spontaneous real-world experience of the system. We connected all of our devices to the Jackery Explorer Pro 1500 Pro, our Wi-Fi router, and several lights, and we kept everything charged and working overnight.

Jackery also boasts about its safety (important when transporting a high-power battery around you), and the unit has an outer casing of “the highest UL requirements” and fireproof material.

Plugging In

The front of the unit is where the connectors are found, but the highlight of the unit’s design is the bright, clear display that shows both input and output power, charging times, and remaining battery life (at the current usage).

The display is bright enough to be seen in sunlight, and it’s the best interface I’ve seen on a power system. There’s no guessing about how long you’ll have juice or how long it will take to charge back up.

Keeps On Keeping On

One of the things I’ve been doing with the system between outdoor shoots is using the Jackery Explorer Pro 1500 Pro as a battery backup system for several 3D printers I’m testing. While the printers take very little power if the power goes out, a job can be ruined, so it’s nice to have a secondary use for the kit.

This weekend my town had a street fair that featured a lot of arts and crafts vendors, and it amused me to think that I could bring 3D printers to a street fair and create output with nothing but the sun.

In addition to our sudden blackout, I’ve used the Jackery Explorer Pro 1500 Pro during a video camera test, leaving the unit in the back of my car and powering my laptop and battery chargers. It would be a perfect solution for location shooters.

I also connected the Jackery to my dryer (gas heat, but electricity for the drum and operation) and a fully charged Jackery Explorer Pro 1500 Pro. It would have gotten nearly six hours of runtime from the system.

Jackery provides some other power use estimates on their site, including running a hand drill for three hours, powering a mini-fridge for 10.5 hours, charging an iPhone 63 times, and running a microwave for 70 minutes.

Here Comes The Sun

The Jackery Solar Generator would be an excellent portable-power solution, but coupling it with high-capacity solar panels makes the unit ideal for backup power and power on the go.

The Jackery Solar Generator 1500 Pro costs 2,699 for the power unit and the 200W solar panel. This isn’t inexpensive, but to put it in context, a Honda 1800W gas-powered generator costs 1,200 and spews fumes.

Are There Alternatives?

Jackery isn’t the only company making solar-driven generators. Electronics maker Anker, for instance, has several systems at a lower price: the Anker 767 system is a 2048Wh generator with two 200W solar panels and costs 2,899. Its closest matching unit to the 1500W Jackery is Anker’s 1229 Wh model, which comes with three 100W solar panels and is 2,000.

I can’t compare the build of the Anker system to that of Jackery since I’ve never used the former, though the company is known for its high-quality accessories.

Should You Buy It?

Yes. While I can’t make a decision of every customer, the Jackery Solar Generator delivers on all of it promises.

Power outages are never fun, but with a portable generator, you can keep your appliances running and lights on even after a storm or blackout. And a portable generator isn’t just limited to emergency preparation—it can also provide a steady power source for RVs, campsites, and tailgating.

“It is important to understand what you want to power/charge when picking a generator. You should look at the wattage needed and pick a generator that can handle that wattage,” says Daniel Majano, a program manager at the Electric Safety Foundation International (ESFI). “In most cases, generators should only be used to power essential devices and never plugged directly into a home’s outlet. Make sure to always purchase a generator with a transfer switch or have a transfer switch installed before using a portable generator without one.”

To find the best portable generators, we researched top options and considered factors like type, wattage, fuel, size, and weight. We also spoke to Majano for his expert insight and safety tips.

How to Shop for Portable Generators Like a Pro

Type

Portable generators fall into three general types: standard, inverter, and standby. Standard portable generators—also known as conventional generators—are the most common. They typically use a gas or diesel-powered engine to power an alternator and generate electricity.

An inverter generator is typically smaller and lighter than portable generators. These models don’t require gasoline and are electric, with a rechargeable battery inside. However, inverter generators may have lower power output than other types of generators. This makes them ideal for powering sensitive electronics like laptops, smartphones, and TVs.

Standby generators connect directly to your electrical system and automatically start when the power goes out. They can run for thousands of hours and are common outside large homes, businesses, and hotels. “A standby generator is a permanently installed generator that instantly turns on during a power outage,” says Daniel Majano, a program manager at the Electric Safety Foundation International (ESFI). “These generators are rated to power a house.”

If you want an eco-friendly alternative, opt for a solar generator, which harnesses the sun’s energy and converts it into electrical power.

Wattage

The wattage on portable generators varies depending on the size and model—the selections on our list go from 1,000 to 6,500 watts. Consider what you need to power and how much wattage is required to fuel it. Smaller generators like the Champion Power Equipment 2000-Watt Inverter Generator (which has 2,000 watts) are ideal for RVs, camping, or fueling a few appliances, but don’t have enough power to be an emergency backup generator. If you want a generator for your entire household, opt for a high-wattage, heavy-duty model like the Ryobi RY906500VNM 6500 Watt Generator With CO Detect.

Fuel

Portable generators typically run on fuels like diesel, gasoline, and propane. However, some portable generators don’t need fuel—they rely on rechargeable batteries or the sun instead. Factor in how long the fuel will last when buying a portable generator. If you want a fuel-efficient generator, opt for an inverter, because they can adjust their engine power based on power requirements.

Size Weight

The size and weight of your portable generator largely depends on its type, fuel source, and dimensions. Small portable generators with a power output of 1,000 to 2,000 watts usually weigh between 30 and 60 pounds, making them perfect for powering small appliances and electronics.

Mid-sized portable generators can weigh between 100 to 200 pounds and have a power output of 3,000-5,000 watts. Though heavy, many of these models come with wheels and sturdy handles so you can lift and move them if needed.

Noise Level

If you’re concerned about the noise produced by your portable generator, be sure to check the manufacturer’s specifications before making a final decision. Portable generators typically have a noise level ranging from 50 decibels, which is comparable to the sound of a running refrigerator, to 60 decibels, which is about as loud as a normal conversation between two people. The WEN Portable Inverter Generator and Jackery Solar Generator 1000 PRO are some of the quietest portable generators on our list and won’t disturb your household or campsite while running.

Safety

To ensure safety while using a portable generator, follow these tips from Majano:

• Never operate a generator inside your home or in a fully or partially enclosed area, including garages.
• A generator should only be used for temporary power.
• Always use a transfer switch and never plug a generator directly into household wiring without a transfer switch.
• Make sure to always have GFCI protection.
• Make sure to have proper carbon monoxide alarms.
• Keep generators at least 20 feet from doors, Windows, and vents to prevent carbon monoxide from entering your home.

Questions You Might Ask

How big of a generator do you need to run a house?

To power an entire house, including large appliances, you will need anywhere from 5,000 to 9,000 watts of electricity. If you want a generator that turns on instantly during a power outage, Majano recommends standby generators, which are rated to power a household.

How many hours a day can you run a portable generator?

“We recommend checking with the manufacturer to see how long a generator can run,” says Majano. Most portable generators can run anywhere from six hours to 18 hours, depending on their power source, size, and type. We also recommend allowing your generator to cool off at regular intervals.

What is the lifespan of a portable generator?

The lifespan of your portable generator largely depends on its type, maintenance, and amount of use. Some models, like gas-powered portable generators, may last for only a few years, while battery-powered generators can last for over 10 years. “We recommend inspecting your generator before and after every use and have a qualified electrician inspect your generator if you notice anything wrong,” says Majano.

The 7 Best Solar-Powered Generators of 2023

Heidi Wachter was a senior editor at Experience Life magazine for 10 years. She has written for publications like Experience Life, Shondaland, and betterpet.

Our top pick is the Yeti 1500X Portable Power Station. However, if you want a smaller, less expensive option, consider the Jackery Explorer 500W.

It’s always good to have a backup in life, especially when the power goes out. Gas-powered generators can do the trick, but they’re loud, emit smelly fumes, and require a place for storing gasoline safely. They also contribute to climate change.

Solar generators, on the other hand, are clean, easy to use, don’t require fossil fuels, and are becoming more and more affordable as solar technology improves. They can be particularly useful in emergency situations where other fuel supplies are cut off or difficult to access. Solar generators typically capture the sun’s energy via stationary or portable solar panels that are sold separately, convert it into electrical power, and store it in a battery for later use.

What’s the best generator for you? First, estimate how much power you need to run appliances, laptops, and televisions in your home should a power outage occur or for whatever you’ll need to power up while you’re camping, living off the grid, or traveling in an RV.

Once you know how many watts you’ll need; consider the other features you want such as USB charging ports and rechargeable batteries. You can avoid blowing your budget by selecting a generator with features that make the unit more efficient rather than more expensive.

We researched the market to recommend the best generators that are compatible with solar panels.

What To Look for in a Solar Generator

When deciding what solar powered generator is right for you, consider which types of appliances, tools, and devices you need to charge and how often you’ll be without a traditional power source. Here are some other tips to help guide your decision-making.

Solar Panels

There are three common types of solar panels—monocrystalline panels, polycrystalline solar cells, and thin film, or amorphous crystal panels. They each offer different efficiency levels. Monocrystalline panels are most common and slightly more efficient than polycrystalline cells. Thin film panels are a newer technology and are light, flexible, durable, and more affordable than the others, but about half as efficient as the other types. Sometimes they’re included with the generator and sometimes they’re sold separately.

Battery Capacity and Power Rating

Solar generators run on stored energy so you’ll want to consider the battery’s capacity (the total amount of electricity stored). You’ll also want to know the power rating (how much power is delivered at a time). A battery with a high capacity, but low power rating typically delivers less electricity for a longer period of time.

Battery Type

Lead-acid and lithium-ion are the most common options. Lead acid are used to power things like automobiles, while lithium-ion options are often used to run power tools. They’re increasingly used in solar-powered generators because they’re lightweight. While they tend to be more expensive than lead-acid varieties, they typically have a longer lifespan which saves money on replacement batteries and keeps them out of landfills.

Charge Controllers

In order to regulate the current between the solar panels and the battery, the simplest controllers cut the power when maximum voltage is reached. This isn’t as efficient as models that use three- power point tracking (MPPT).

Inverter

Converting direct current (DC) from solar panels to alternating current (AC), inverters carry a watt rating to show the maximum output of power they can generate. Pure sine wave inverters are more expensive, but more efficient. But they’re not necessarily a cost-effective option if you only plan on using the generator occasionally.

Weight

Will you be using your solar generator in your home or on the go? For portability, look for units that are easier to carry and maneuver, and that house parts in a sturdy box rather than as separate pieces.

Other Features

Note the presence of multiple USB ports and AC outlets, replaceable batteries, and LED panels that help you monitor your system when it’s dark. Finally, consider the length of a unit’s warranty, or any other manufacturer grantees.

When determining the size of generator, you’ll want to look at output measured in watts, as well as storage capacity measured in watt hours (Wh). As a general rule of thumb, generators with under 1000 Wh can keep electronics charged, and are great for camping. To power many devices in your home for longer, you’ll want a large generator with around 1500 Wh capacity.

If you want to keep those devices charging and in use for five hours:

So, in this case you’d want a generator with at least 85 watts of output and 425 Wh of capacity. When in doubt, round up. For another way to calculate your needs, you may find this explainer from the manufacturer Jackery helpful.

Keep in mind that most solar generators do not connect to your home’s electrical panel, so they won’t power hard-wired devices like your hot water heater or ceiling lights; for that type of power you’ll want to consider a home battery system.

Solar generators should last at least 20 to 25 years. Many manufacturers offer warranties that cover repairs and replacements should anything malfunction within the first few years of use.

Most high-capacity solar generators cost between 1000 and 2000. Generally speaking, larger generators cost more than smaller, portable devices. The generators on the list range from between 140 and 3,400 without taking into account sales or discounts.
