Buying guide · Updated Sep 27, 2026
For outages, capacity and output matter most. A full-size fridge alone uses 1 to 1.5 kWh a day and needs up to 1,200 W to start its compressor; add a router, lights and phones and you're near 2 kWh a day.
We rank stations of 1,000 Wh or more on capacity, output, battery longevity and value, with a bonus for instant UPS switchover. Plug your own appliances into the runtime calculator to see how long each one lasts.

Best overall
Why it's here: The best big power station for RVs, and the lowest cost per Wh here.
Runner-up
Why it's here: The best portable-ish home backup here — plan for its weight and idle draw.
Also great
Why it's here: Still capable, but the newer 3 kWh units are better value unless you need its solar and expansion.
Pick #4
Why it's here: The best value in the whole catalog for outage backup.
Pick #5
Why it's here: The best value per watt-hour among the 1 kWh stations — if you don't mind the weight.
Ranked lower on this guide's criteria.
Estimate your daily watt-hours, then multiply by the days you want to cover without recharging.
Fridges, freezers, sump and well pumps need a brief surge well above their running watts. Surge ratings of 3,000 W or more handle most homes.
A 10–20 ms switchover keeps a router, PC or CPAP running when the grid drops, without you touching anything.
Expandable models and 500 W+ solar input let you ride out multi-day outages.
About 30–40 hours for a typical full-size fridge using 1.2 kWh a day, after inverter losses. Newer, smaller fridges last longer.
Not a whole house at once. Large units (3,600 W) paired with a transfer switch can run selected circuits like the fridge, furnace blower, lights and a well pump.
Yes, most can sit on the charger in UPS mode. Some models draw 15–35 W at idle with the inverter on, so switch AC off when you don't need it during an outage.
