2. Jackery Explorer 2000 v2 – best overall pick
The Jackery Explorer 2000 v2 delivers 2,042Wh capacity with 2,200W continuous output in a package that one person can actually move. This portable battery generator strikes the right balance between power and portability at 39 pounds. You get enough capacity to run a refrigerator for 8.6 hours or recharge your phone 86 times without the bulk of units that require wheels and handles.
Why we picked it
You’ll find the 2000 v2 provides sufficient power for most scenarios without paying for capacity you won’t use. It handled our simultaneous load test of a space heater, blender, and LED lights without strain. The unit reaches 80% charge in just 100 minutes through AC input, which beats many competitors that take 3+ hours for similar capacity. Testing showed it delivers 84% of its claimed capacity as usable AC power, one of the highest efficiency ratings we measured.
Key specs to know
The unit outputs 2,200 watts continuously with 4,400 watt surge capacity for starting power tools and appliances. You get three AC outlets, two USB-C ports (one at 100W), one USB-A port, and a 12V car outlet. The LiFePO4 battery lasts for 4,000 charge cycles before dropping below 80% capacity. Actual measured output reached 1,710Wh from the 2,042Wh claimed capacity.
The high efficiency rating means more of your stored power actually reaches your devices instead of getting lost to heat and conversion.
Best uses and limitations
This power station excels at weekend camping trips and short outages. You can run an electric cooler overnight, power LED string lights, and keep phones charged throughout a two day trip. It handles most kitchen appliances except those requiring sustained high wattage. The unit cannot expand capacity with additional batteries, so what you buy is what you get.
Charging and solar options
Wall charging takes 2.5 hours for a full charge at 817Wh per hour. You can add up to 400 watts of solar panels for off grid recharging, though you’ll need Jackery’s adapter cable for third party panels. Car charging through the 12V port works but takes considerably longer.
Price and who it is for
The 2000 v2 costs $1,499 and targets people who need reliable backup power without industrial level capacity. You’ll appreciate this unit if you want practical emergency power for outages or comfortable camping without the weight penalty of larger systems.

This unit weighs 113 pounds and sits on wheels with a telescoping handle, making it realistic to move around your home despite its size. You get enough power to run essential circuits for multiple days when you pair it with the optional expansion batteries that increase capacity to 48kWh total.
Why we picked it
Testing revealed the Delta Pro 3 delivers 97% efficiency, the highest we measured in any unit. You can run a full size refrigerator for over 51 hours straight or power a space heater at 1,300 watts for nearly 6 hours. The X-Boost feature kicks in automatically when your load exceeds 4,000 watts, letting you start high draw appliances without manual intervention. We pushed it past 5,000 watts simultaneously running an air fryer, toaster, space heater, and miter saw without any performance issues.
Key specs to know
You’ll find four AC outlets, one 30-amp RV outlet, one 240-volt plug, and four USB ports spread across the unit’s control panel. The system charges from 0% to 80% in under 2 hours through standard AC input, reaching full capacity at 2.6 hours. Maximum solar input accepts 2,600 watts through dual solar ports. The LiFePO4 battery survives 3,500 charge cycles before capacity drops below 80%.
The 240-volt outlet opens up options for powering larger appliances like electric dryers or ranges that smaller units can’t handle.
Best uses and limitations
This power station excels at whole home backup through a transfer switch that connects directly to your breaker panel. You select which circuits to power during outages, then flip the switch when grid power fails. The unit handles multi-day outages when you add expansion batteries and solar panels. Moving it requires the built-in wheels since one person cannot safely lift 113 pounds alone.
Charging and solar options
Wall charging delivers 1,412Wh per hour, the fastest rate we tested. You can connect to EV charging stations with the optional adapter for even quicker recharges. Solar charging supports up to 2,600 watts across two input ports, though you’ll need direct sunlight to reach peak performance.

You get enough muscle to handle any appliance or tool combination, plus the option to expand total capacity to 53.8kWh when you add battery packs and a second F3800 Plus unit.
Why we picked it
Testing showed the F3800 Plus handled our combined load of four power hungry devices without strain. We ran a miter saw, table saw, blender, and space heater simultaneously, pulling over 4,000 watts consistently. The unit maintained steady power delivery throughout our test, demonstrating its capability for serious home backup or RV use. Four sturdy wheels and the vertical design make it easier to move around tight corners and hallways compared to other high capacity models.
Key specs to know
You’ll find six AC outlets on this unit, eliminating the need for power strips during testing. The system includes one RV port and one 240-volt outlet for connecting larger appliances like electric ranges. USB charging options include multiple ports for smaller devices. The LiFePO4 battery delivers 3,230Wh of measured usable power from the 3,840Wh total capacity. Maximum solar input reaches 3,200 watts across two ports rated for 165 volts each.
The high voltage solar input means you can recharge this beast in under two hours of direct sunlight when you connect enough panels.
Best uses and limitations
This power station excels at powering RVs and serving as whole home backup for extended outages. You can run full size appliances, multiple power tools, and keep essential circuits active for days. The 135 pound weight makes it impractical for camping trips where you need to carry gear, though the wheels help with short distance moves. Small footprint lets you tuck it into corners when not in use.
Charging and solar options
Wall charging reaches 80% capacity in under 2 hours through standard outlets, hitting full charge shortly after. You can add up to 3,200 watts of solar panels for off grid recharging, which cuts charge time significantly on sunny days.
