How We Choose the Best Solar Generators

As an avid outdoor enthusiast, I had the opportunity to test an extremely wide range of outdoor gear, including mobile and off-grid electrification devices such as solar generators. These became especially important when the pandemic forced my trips to be domestic rather than international, which prompted me to equip a van for long-term road trips.

To carry my work with me, I need a constant power source to charge my laptop, portable refrigerator, lighting, and countless devices and tools. As a result, I’ve tried all the leading portable power stations (and many that aren’t), so I know exactly what’s the best and crap. I’ve written all about it (and other outdoor tech) for publications like The Daily Beast, Thriller, Handbook, and more. In some cases, my own opinion has led to a tie, so I looked at actual customer reviews to determine which solar generators provided the most satisfaction for most users.

Things to Consider Before Buying a Solar Generator

Solar generators have exploded in the market over the past few years. There are now dozens of different brands, which at first glance look roughly the same. The truth is, out of the vast number of knockoffs, only a few stand out. Here’s to make sure you get great content.

How much power can be stored

Portable solar generators come in a wide range of sizes, but the size of a generator doesn’t automatically allow it to store a lot of electricity. In fact, most are disappointingly limited and can’t store 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). A watt hour is equivalent to 1 watt flowing in an hour. The best solar generators provide hundreds of watt-hours of capacity, and in some cases even several kilowatt-hours. However, that doesn’t mean it will provide hundreds or thousands of hours of power. Any generator will end up lasting different times depending on what’s plugged in.

When you use a generator to power one thing, it’s easy to predict how long the generator will last. For example, if you were to use a 500-watt-hour power station to power a 100-watt light bulb, it would stay on for 5 hours continuously. Add a portable refrigerator that takes 50 watts per hour, a phone that uses 18 watts, a mini fan that uses 3 watts… you get the idea. The bigger the capacity, the better.

Charging capacity

No solar generator will keep charging forever, so you need a generator that can charge as quickly and easily as possible. This is where we turn “renewable energy” into “renewable energy”.

All of the power stations included in this roundup can be charged by connecting them to a solar panel (hence the name “solar generator”), but you’ll also want to look for 12-volt plugs through wall sockets and vehicles. This ensures that you can charge it off-grid in the sun, while preparing at home, or charging from the dash socket on the go.

You also need to pay attention to the charging input capacity of the model in watts (W). For example, a solar generator with a maximum input of 100W can receive up to 100W of continuous flow, which is about the minimum you would reasonably want to look for. Most of the generators included below have an input capacity of at least a few hundred watts when charged by the sun, so some 50 to 200 watt solar panels maximize them.

Output capability

Solar generators are needed to keep power coming in and out. The best solar generators are able to charge all your intended devices at the same time through any necessary plug.

Any portable power station worth your money will have a high output capacity so you can charge many devices even if they need a lot of juice. The generator’s maximum output should be much higher than its maximum input. While a particular model may only draw a few hundred watts at any given moment, it’s usually multiplied. At a minimum, you’ll need a generator that can put out 300 watts at a time, but for larger tasks you’ll need at least 500 watts.

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, such as those found in a car’s dashboard. This ensures that you can charge multiple devices at once, no matter what plug they use. The number of ports you need depends on how many devices you need to power, but it should have at least a few AC outlets and a few USB-A ports.

Portability

While portable battery power sources have been around for a while, they’ve been pretty heavy, bulky things for the past few decades. One of the most exciting aspects of the latest generation of solar generators is that their physical structure has become more compact.

If you plan to camp the generator or convert it into a van where every square inch counts, size and weight will be major considerations. All of the products we recommend are the size of a shoebox or two – up to three. The lightest is about 24 packs of soda, while the heaviest is 100 pounds, or about the weight of a king-size bag of dog food. Most fall between 30-60 lbs.

If you plan to use the generator as a more or less stationary backup power source in your home, portability isn’t a huge issue. We generally recommend keeping weight and size in mind, though; you never know when you’ll need it for something other than backup. (Plus, who wants to drag something heavy and awkward if it doesn’t have to?)

Another consideration in portability is the need for accessories, which affects how easy it is to move and use the generator. For example, some generators require a large removable battery pack, which can be a hassle when you’re on the go or packing your vehicle. Everything on our list requires a few 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 paramount. This is especially true if you plan on lugging your generator around on camping and road trips. A lot of the sub-par power stations are made of cheap components and flimsy plastics that feel unbearable on harsh roads.

Durability is not something you can determine by reading spec sheets from the internet. You actually have to take the generator out, use a bunch, and see how it holds up. I’ve verified the durability of these recommendations by combining my own actual field tests with reviews from countless real product owners.
