Best overall
EcoFlow DELTA 3 Plus
- 1,024 Wh
- 1,800 W out
- 3,600 W surge
- 27.6 lb
A strong 1,800 W inverter handles a fridge plus a microwave or coffee maker, and it's the only 1 kWh pick here you can expand later (to 5 kWh) as your needs grow.
Fridge alone: about 15 hr. CPAP (no humidifier): about 22 hr.
Lightest 1 kWh
Jackery Explorer 1000 v2
- 1,070 Wh
- 1,500 W out
- 3,000 W surge
- 23.8 lb
At 23.8 lb, it's the easiest of the 1 kWh group to carry, with slightly more capacity (1,070 Wh). A good fit if you'll move it room to room.
Fridge alone: about 15 hr. CPAP (no humidifier): about 23 hr.
Most output at 1 kWh
Anker SOLIX C1000 Gen 2
- 1,024 Wh
- 2,000 W out
- 3,000 W surge
- 24.9 lb
2,000 W of output is the most in its class, so it copes best with a kitchen appliance running alongside the essentials.

- 2,042 Wh
- 2,200 W out

Questions
What size power station do I need for a power outage?
For phones, Wi-Fi, lights and a CPAP, about 300 Wh covers a night. To keep a full-size fridge running too, plan on 1 kWh or more per day. Use the calculator to size it to your own appliances.
Can I use a power station indoors?
Yes. Battery power stations make no exhaust, unlike fuel-burning generators, which must stay outdoors and at least 20 feet from doors, windows and vents.
Can a power station run my furnace?
It can run a gas furnace's blower, which typically draws a few hundred watts, but most furnaces are hard-wired. Connecting one needs a transfer switch or inlet installed by an electrician.
