Best Small Portable Solar Generator: Anker SOLIX C300
Introduced in late 2024, the Anker SOLIX C300 is a wonderful surprise. Its unique vertical form factor is something new that was instantly a huge hit among our review team. Compared to other products in its size class, it is more usable and fun to tote around than anything else on the market.
The regular SOLIX C300 comes with three AC outlets, but there is a second, DC-only version of the SOLIX C300 that’s great if you just need USB and 12V cigarette lighter ports (and it comes with a bonus pop-up light built into the top).
Why we chose the Anker SOLIX C300
Simply put, the Anker SOLIX C300 is a joy to use and carry around, and it’s cute as a button. Its storage capacity is enough to charge several devices for a few days without recharging, and it can even do something fun like run a projector, speaker, and string lights for a movie night under the stars.
When it comes time to recharge the C300, you can use a solar panel with a maximum of 100 watts (11-28 volts), which will take several hours of full sun to bring the unit from 0% to 100%.
With just 300 watts of maximum continuous output and 288 watt-hours of capacity, the C300 doesn’t have enough power to run a coffee maker or space heater. But it does offer UPS backup power functionality with under 10 ms switchover time, meaning it can help keep low-wattage devices like a CPAP machine running without interruption in the event of a power outage.
At under 10 pounds, this is the perfect entry-level portable power station, and we recommend it to anyone, even if you plan on getting a larger solar generator to handle bigger tasks.
Pros and cons of the Anker SOLIX C300
Pros | Cons |
|---|---|
Ultra-lightweight, portable, and cute | Not powerful enough to run coffee makers and space heaters |
Powerful enough to charge laptops and smart phones, or run small electronics like projectors and speakers | |
UPS functionality protects you from interruptions due to a power outage | |
Comes from a reliable brand with a great 5-year warranty |

Best Midsize Portable Solar Generator: EcoFlow DELTA 3 Plus
EcoFlow is one of the preeminent brands in the portable power station game, and the company revamped its lineup in 2024 with the third generation of its main product series. The DELTA 3 Plus is our #1 pick for midsize portables (around 1 kWh of storage).
Why we chose the EcoFlow DELTA 3 Plus
The DELTA 3 Plus comes in with a slightly lower capacity than some of its competitors (such as the Bluetti AC180), but it’s expandable, and the reduced weight of the main unit makes it easier to carry than other power stations in its class.
With 1,800 W of continuous power output, this is one capable unit which can run demanding appliances like space heaters and coffee makers with no sweat. When used as a backup power source, the DELTA 3 Plus has a UPS mode with under 10 ms switchover time, meaning it can stay plugged in between the wall and sensitive electronics like computers, modems, routers, and network-attached storage devices to keep them running in a blackout.
Expandability and interconnectedness are the main selling points of the DELTA 3 Plus as well, with various EcoFlow Smart Extra Batteries able to increase the storage capacity by 2 to 5 times, and the company’s Smart Generator 3000 able to recharge the battery if it gets too low.
When it comes to solar recharging, the Delta 3 Plus can handle up to 1000 W of input power via its XT60i connector, which can recharge the unit in under 2 hours of full sun. If you want to save a few bucks and don't mind half the solar input, check out the non-Plus EcoFlow Delta 3, which offers nearly all the same specs and expandability as the Plus model, but only half the solar input.
Pros and cons of the EcoFlow DELTA 3 Plus

Best Large Portable Solar Generator: EcoFlow DELTA Pro 3
The 114-pound king-sized candy bar of the EcoFlow lineup is our best large portable solar generator of 2025. This large unit is basically the Swiss Army Knife of solar batteries, with tons of input and output options that can take it from the campsite to the job site and even into your mechanical room as a partial home backup system.
Why we chose the EcoFlow DELTA Pro 3
The EcoFlow DELTA Pro 3 offers a huge 4,096 Wh of energy storage—more than any other portable power station—but packs it into a relatively small footprint. Yes, it weighs 114 pounds, but it makes up for that by adding a sturdy, stow-able handle and two heavy-duty wheels, making it relatively easy to roll around. When you need it off the ground, lift with your knees, and preferably a partner.
With 4,000 watts of power output, The DELTA Pro 3 can power a 2.5-ton air conditioner, and you can triple the power output up to 12 kW with up to three additional units in parallel. The DELTA Pro 3’s expandability includes additional battery storage, up to 12 kWh, with two additional Smart Extra Batteries.
The real reason the DELTA Pro 3 is the star of the show is its versatility. It accepts solar power from two different arrays (low voltage and high voltage); it offers a dedicated NEMA TT-30R for plugging directly into the shore power connection of an RV, a special 240V outlet for home appliances, and more. EcoFlow is also building an ecosystem around its large power stations, including installation consultations for its Smart Home Panel to provide home backup.

Best Premium Portable Solar Generator: Bluetti Elite 200 V2
We named the Bluetti Elite 200 V2 the best premium portable solar generator for 2025, and truth be told, it may be one of the only solar generators on the market that can qualify for the title.
We use “premium” here to refer to the compactness and performance of the flat-packed automotive-grade battery cells inside the unit. These cells allow Bluetti to pack more storage into a smaller footprint than any solar generators that use cylindrical cells.
Why we chose the Bluetti Elite 200 V2
At this point, we’ve done hands-on testing with more than 10 different Bluetti solar generators, and they are always a staff favorite. The company is known for creating excellent products that people love, and the Elite 200 V2 lives up to that reputation.
It’s compact and easy to use, and it has massive power output for the size. We also love how Bluetti has introduced a special new car alternator charger, which uses a DC solar charging cable to connect your power station directly to the output of your car’s alternator.
Finally, the automotive-grade lithium iron phosphate (LiFePO4) battery cells inside the Elite 200 V2 are designed to last longer than commodity-grade cylindrical cells. Bluetti’s pioneering work in bringing ultra-high-quality cells to the market and backing them up with a great warranty earns our recommendation!
Pros and cons of the Bluetti Elite 200 V2
Pros | Cons |
|---|---|
Compact, energy dense, and powerful | MSRP is slightly expensive (but is on sale often) |
Uses special automotive-grade lithium iron phosphate cells designed to last longer than traditional cells | Missing some ports that RVers want |

Best Affordable Solar Generator: OUPES Mega 1
OUPES (pronounced like “opus”) is a brand that targets a more value-conscious customer but is always upping its game when it comes to functionality and power. The Mega 1 is the first OUPES solar generator we’ve tested that is expandable with additional batteries, and we love the features OUPES has packed in for the price.
Why we chose the OUPES Mega 1
The Mega 1 is a portable power station that can output 2,000 watts continuously, holds just over 1 kWh of energy, is expandable up to 5 kWh, has a <20ms UPS mode, and can recharge from up to 800 W of solar panels, or a combined 2,200 W of AC power from a wall outlet.
And it does all that for about ⅔ the price of the other brands on the market. Not only that, but OUPES products have proven their reliability in our testing, and the company stands behind their products with a 3-year warranty.
Pros and cons of the OUPES Mega 1
Pros | Cons |
|---|---|
2 kW power output and a bit over 1 kWh of energy storage | More expensive brands offer better warranties |

How our team evaluates solar generators
Our evaluation of the best solar generators starts with a look at the numbers. We’ve created a tool that allows us to compare dozens of batteries based on their power output, storage capacity, price, weight, dimensions, types of inputs and outputs, solar charging capabilities, and other factors unique to each generator.
Then we test each battery individually, taking measurements of their physical aspects (weight, dimensions, materials) as well as their ability to output power to devices, charge from AC and solar, and how they work in practical applications.
This real-world testing proved vital in forming our opinions about the best battery for each category.
A note on battery chemistry: All portable solar generators we tested use LFP (lithium iron phosphate) battery cells. LFP is an extremely safe, stable, long-lasting, and non-toxic battery chemistry compared to other chemistries. LFP cells make a battery a bit heavier than some alternatives, but these cells have no risk of thermal runaway and last around seven times as long. We only considered LFP batteries for our ranking.
How to decide which solar generator is right for you
To decide which solar generator is best for you, it’s best to first think about all the things you’ll want it to do and work to find one that can meet your needs.
Here’s what you should look for:
Continuous power output: Make sure the generator puts out enough wattage to safely run all the devices you intend to plug in and run at once.
Energy storage capacity: Look for enough battery capacity to meet your needs over time. Take the wattage of appliances multiplied by the number of hours you want them to run. For example, say you want to run a 700-watt coffee maker for 10 minutes a day: it will use 700 watts times 1/6th hour, or 116 watt-hours of stored energy. Do the same calculation for all the devices you plan to use.
Portability: Decide how much weight you want to deal with moving around. Batteries can get quite heavy, and many people might want to have more than one solar generator to make it easier to move individually.
Specific power attributes: These are things like having a 30-amp RV outlet, accepting a certain voltage range of solar panels, or being able to run your DC fridge. People who already have a solar panel or RV may find these to be very important factors, while others will be able to match future purchases to the capabilities of the generators they buy.
Here’s a breakdown that shows average output, capacity, and weight of popular solar generator options to help you decide what category you might be looking for:
Output | Capacity | Avg. weight | Best for |
|---|---|---|---|
~300 W | ~300 Wh | 10 lbs | Charging small devices on the go on hiking trips, backyard movies, running computers for a few hours |
~600 W | ~700 Wh | 20 lbs | Overnight and weekend camping trips with phones, laptops, small lamps, cameras, etc, with or without solar recharging |
~1,200 W | ~1,000 Wh | 29 lbs | Trips with more power needs (e.g. small coffee maker), with or without solar recharging |
~1,800 W | ~1,200 Wh | 34 lbs | Off-grid living in a van or small RV, with daily solar recharging. Suitable for toasters, hair dryers, microwaves, etc. |
~2,400 W | ~2,000 Wh | 53 lbs | Running all appliances in an RV with daily solar recharging, small home backup for emergencies |
~4,000 W | ~4,000 Wh | 115 lbs | Seriously large RV applications, partial-home backup, running power tools at a worksite |
Final thoughts
There are now many companies making excellent solar generators for off-grid and home use. The list above includes our top picks for the various categories.
You can take our word for it, but you can also use our general guidelines for what to look for to identify the best solar generator to fit your specific needs. We left out some bigger names like Jackery Explorer and Goal Zero Yeti because their products don’t thrill us, but they each have some decent offerings, and we encourage you to apply the knowledge you gained from this article in deciding if one is right for you (just make sure you’re getting LiFePO4 battery cells).
Pretty much every one of these companies makes a solar generator that can fit your needs, so if you find one you like best, explore the options on the market. Once you find the right one for you, learn how to choose the right portable solar panel to charge it up.
