How we selected 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. 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. As a result, I’ve tried all of 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.
What to consider before buying a solar generator
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?
Portable solar generators come 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 need to 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 in some cases 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 5 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.
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”), but 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 whenever you’re off-grid in the sun, plugged in while preparing at home, or while on the go via your dash socket.
You also need to keep an eye on a model’s charging input capacity, which is measured in watts (W). A solar generator with a max input of 100W, for example, 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 included 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.
Solar generators need to keep the power coming in and going out. The best solar generators are capable of charging all your intended devices simultaneously 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’re going to want a generator that can put out 300 watts at a time, though for larger tasks you’ll want at least 500.
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 that you can charge several devices at once no matter what plug they use. 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 involves the fact that they’ve become much more physically compact.
If you plan on taking a generator camping or will be working it into a van conversion where every square inch matters, 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, or roughly the weight of an extra-large bag of dog food. Most fall somewhere between 30-60 pounds.
If you’re going to be 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 when it comes to 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. A lot of 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.

- Dimensions: 9.1 x 5.2 x 7.8 in
- Weight: 7.1 lbs
- Reasonable capacity
- No flashlight
- Slower input capacity
Though it isn’t quite as impressive as our top pick for best solar generator, 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 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, this highly portable little power station does a lot for a little.
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, say, 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:
1. 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.
2. Add up the total wattage necessary: the two bulbs are 60 watts each, so you need 120 watts.
3. 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 keep in mind 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 wasn’t capable of charging 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 all over the country. 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.
