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 high-capacity: Jackery Explorer 3000 Pro

Specs

• Storage capacity: 3,024Wh
• Output capacity: 3,000W
• Dimensions: 18.6 x 14.1 x 14.7 inches
• Weight: 63.9 pounds
• Price: $2,799

Pros

• 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

Cons

• 200W solar panels can be klunky
• Relatively pricey

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.

Specs

• Storage capacity: 2,048Wh
• Output capacity: 2,400W
• Dimensions: 20.67 x 9.84 x 15.55 inches
• Weight: 67.3 pounds
• Price: $1,999

Pros

• 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

Cons

• Heavy for its capacity
• No USB-C in for charging

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. 

Specs

• 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

Pros

• Highly portable
• Incredible durability
• Rapid recharge rate
• Plenty of plugs

Cons

• Expensive for its size/capacity

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.

• Massive capacity
• Daisy-chain capability
• Lightning-fast input capacity
• 30A RV plug and two wireless charging pads
• Surprisingly affordable for what it offers

Cons

• Pretty heavy
• Fan can get loud, especially in hot weather

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

Buy it used or refurbished: eBay

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

Specs

• 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

Pros

• Enormous capacity
• Daisy-chain capability
• 30A RV plug
• Lightning-fast input capacity
• Wi-Fi and Smartphone connectivity

Cons

• Very heavy
• Expensive

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.

Specs

• Storage capacity: 778Wh
• Input capacity: 240W
• Output capacity: 770W
• Dimensions: 11.81 x 8.03 x 7.28 inches
• Weight: 18.2 lbs
• Price: $559.99

Pros

• Lightweight and compact
• Plenty of capacity
• Built-in lights

Cons

• Slower input capacity

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.

Specs

• Storage capacity: 293Wh
• Input capacity: 90W
• Output capacity: 300W (500W surge)
• Dimensions: 9.1 x 5.2 x 7.8 in
• Weight: 7.1 lbs
• Price: $250

Pros

• Affordable
• Durable
• Portable
• Reasonable capacity

Cons

• No flashlight
• Slower input capacity

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.

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.
