Whole-house backup is a generator's job. A power station keeps the essentials alive: the fridge, the router, a CPAP, some lamps. This page ranks the 12 stations we track for that job, keeping each unit's existing 0-10 spec score and surfacing the three columns that decide how long the essentials stay on: capacity, inverter output, and solar input.

The shortlist
Match the outage you actually get, then check the math below.
EcoFlow
Top score of the 12 we track: 4,096 Wh runs a fridge's 60 W planning average for about 2.4 days, and a 2,600 W solar input can refill it in good sun.
Tip: add it to your Amazon cart while you decide — it stays saved there, with no obligation to buy.
Jackery
2,042.8 Wh and a 3,000 W inverter at 61.5 lbs: fridge math lands near 28.9 hours, and the inverter covers kitchen loads the 300 W units cannot.
Tip: add it to your Amazon cart while you decide — it stays saved there, with no obligation to buy.
EcoFlow
The highest-scored 1 kWh unit on the table: 1,024 Wh, 1,800 W, 27.6 lbs. Fridge duty works out to about 14.5 hours per charge.

Scope check
The planning figure for a refrigerator is a 60 W average (a 150 W compressor at a 40% duty cycle), the same number our outage runtime guide publishes. Add a router at 15 W and a few LED lamps and the essentials bundle stays near 215 W, well inside any 1 kWh unit's inverter.
Central air conditioning, electric water heaters, and ranges sit outside this product class. If those loads must run, the honest answer is an inverter generator, and we score those on a separate page.
Multi-day reality
A battery only bridges to the next charge. Solar input decides whether day three looks like day one: the tracked stations accept anywhere from 100 W to 2,600 W of panel input, and the refill table on our 1 kWh guide shows the ideal-sun arithmetic for that class.
We do not track UPS or EPS switchover times. If the fridge or a medical device must ride through a cutover without a blink, confirm that rating with the manufacturer before buying.
