Though we love our minimalist adventures, off-grid outings don’t just mean an ultralight pack setup and cold-soaked oats in a dew-soaked tent. Overlanding, glamping, and van-based remote work have grown in popularity over the past several years, allowing more versatility in the items you bring for comfort and convenience. This often means battery-powered items, whether it’s a smartphone, computer, rechargeable lights, or even a powered cooler or fridge.

These days, you have options beyond running a gas-powered generator to keep the lights on and the computer charged. Solar-powered generators—also called portable power stations—are a growing sector of the power market and offer clean, efficient charging systems for off-grid adventures and power outages.

The past few years have seen significant advancements in portable charging stations, with units becoming more compact, affordable, and with better charging capabilities than before. Think of them as giant versions of battery power banks used to charge phones during travel or when outlets are scarce. Each unit holds a certain capacity for charging devices, measured in watt hours, or WH.

Most power stations can be charged in a wall outlet, a car’s 12-volt port, or with solar panels (often sold separately). Once the charging station is juiced up, you can charge battery-powered gadgets on the go, or keep lights running off-grid. Some of the more high-powered units can even run household appliances during a power outage.

We’ve rounded up the best models on the market, taking into consideration charging capacities, ease of use, weight, and different people’s power needs. Lastly, “solar-powered” doesn’t mean you need the sun to charge these power stations. They all have the capability to charge with solar panels, but almost all of them can charge in an AC wall outlet or with a 12-volt car adapter.

Best Solar-Powered Generators

The Expert: I have been traveling in the outdoors for as long as I can remember, and I’ve spent the past decade reviewing camping gear, overlanding items, and other outdoor equipment. I take multiple extended car-camping trips each year with a portable, convenient setup that includes barely more than a bin of car-camping goods, a piece of memory foam, and the topper on my truck.

Since I’m usually working while I’m on the road, my main charging needs are personal devices like a phone, laptop, and headlamp. My go-to portable power solutions are typically mid-range in size and capacity, as I don’t need a ton of charging on the road like someone powering the lights in a trailer or RV would need.

What to Consider

How Much Charging Do You Need?

One of the main differences in these models is how much charging capacity they each have. Consider the electronics you plan to pack, and how much juice you’ll need for each one. This can also pertain to generators you keep at home for power outages.

For instance, running a refrigerator will take a lot more power than recharging your phone or powering your lights. Consider making a list of the items you’ll need to charge or power, and how much each one needs to run. From there, consider how much time you’ll be off grid, and how long the solar-powered generator will take to recharge once it is depleted.

Charging Capacity

This goes hand in hand with your needs. Once you figure out what you’ll be charging, you can start comparing capacities per full charge on each unit. The price goes up as the capacity increases, but most people heading out for an off-grid weekend will want at least around 40 amp-hours, or 500 watt-hours.

If you’re looking for a home-powering backup for power outages, look for a model with at least 100 amp-hours and we recommend 200 watts of solar panels for recharging. Keep in mind that solar panels are not usually included with the unit, and we recommend buying both at the same time for maximum efficiency in charging.

We listed the watt hours as “wh” in the specs for each model for easier comparison.


While weight and size don’t directly connect to the technicalities of power banks, they impact the convenience of each model. Many campers and overlanding setups have limited space, so the more compact models have a higher appeal.

That said, most units weigh at least 10 pounds, and the weight and size increase quickly with greater capacities. Before purchasing, consider where you plan to store the power bank, and the space in your vehicle or camper where it will live while you’re on the road.

How We Selected

As we chose the best solar-powered generators, we compared charging capacity, weight, and power input. We chatted with overlanding experts and car campers, and looked for a range of models that would suit everyone from users with less charging needs and space to people looking for a backup for household appliances.

It’s all about compromise, which means balancing charging capacity with weight and price. The heavier models with lower charging capacities and longer recharge times didn’t make the cut, and we did our best to balance the criteria for a variety of models that suit different needs.

Explorer 1000 Portable Power Station

This all-around winner has a max capacity of 1,002 watt-hours, which is lower than others on this list, but still has the ability to power items for longer than other higher-capacity models. This is an ideal power station for smaller items and off-grid camping, but with the lower output, you won’t be able to run larger appliances.

This model has eight ports, including two AC outlets, two USB-C ports, a 12-volt car port, and two standard USB-A outlets. It can charge a typical laptop eight times and power a small refrigerator or powered cooler for over 15 hours.

This unit can be charged with solar panels or a 12-volt outlet in your vehicle while you’re on the move. It has fairly standard charging times, with 11.5 hours in a car outlet, 6.5 hours for solar panels, and just 5.5 hours to fully charge in a wall outlet.

Charging Tips to Keep Your Solar-Powered Generator Running From Expert Maggie Slepian

What are your priorities when choosing a solar-powered generator?

I am a low-maintenance camper, and most of my background is in lightweight backcountry travel. That means I prioritize space-saving and ease-of-use, so my go-to power banks have between 500 to 800 watt hours, and weigh less than 15 pounds.

This is perfect for a weekend trip, with the on-the-go (car or solar) charging capabilities to put my mind at ease for longer trips. Mostly I’m charging small items, so one charge lasts a long time. However, plenty of people in the van-life and remote-work world are powering their RVs and vans, and relying on multiple laptop charges. For that, I’d recommend one of the larger units.

What can a solar-powered generator charge and power?

A solar-powered generator can charge and run almost anything that requires power—it just depends on the capacity. These generators can charge power tools in the shop, laptops for remote work, and personal devices like bluetooth headphones and speakers.

A solar-powered generator with a higher power capacity can even power household appliances in the event of a power outage. And the fact that these are solar-compatible means you aren’t reliant on the electrical grid to recharge them.

What is the best way to charge a generator?

Every unit on our list has multiple charging options, including wall (AC outlet), car (12-volt), and solar. Each input method charges your unit at a different speed, and solar also depends on the conditions.

I try to charge up my power banks whenever I can, so I’m never caught off guard trying to leave on a trip with a dying power bank. If this happens (which it has), I’ll charge it in my car’s 12-volt port while I’m driving, though this is often slower than solar or a wall unit.

Solar power is the most sustainable and typically fastest way to power these, just be sure you have enough wattage in the solar panels to make it effective. I recommend keeping the generator stored with at least an 80 percent charge, and unplug them once they’re fully charged—keeping them plugged in longer than necessary can degrade the battery.

Most units will have a simple readout display showing the remaining battery charge, and it’s a good practice not to allow your battery pack to get below 20 percent.
