For a fridge or freezer, prioritize a verified surge rating well above the compressor's startup spike and roughly 1,000-1,600 Wh of usable capacity per day of outage — the shortlist and comparison table below rank the catalog on exactly those fields.
Keeping food cold through an outage is a focused job: handle the compressor's startup surge, then supply roughly 1,000-1,600 Wh per day for as long as the power is out.
This page covers battery-based portable power stations, not fuel-burning generators. A power station runs silently, indoors, with no exhaust, no fuel to store, and no fumes — it stores a fixed amount of energy (its Wh capacity) and needs recharging (wall, car, or solar) once that runs out. A fuel generator can run indefinitely on stored gasoline or propane but must run outdoors, away from windows and doors, because of carbon monoxide risk, and needs fuel stored and rotated. For a single fridge or freezer during a typical outage, a correctly-sized power station is usually enough and avoids the fuel and ventilation logistics entirely; a fuel generator becomes the more practical choice mainly for loads or outage durations well beyond what a station's battery capacity can cover.
These picks are focused on the U.S. market. Before buying, confirm plug type, voltage (120V), warranty terms, and regional availability on the Amazon listing — especially if you are ordering to another country.

As a planning estimate, capacity_wh × 0.85 ÷ daily energy. For a fridge using 1,200 Wh/day, a 1,024Wh unit is roughly three-quarters of a day. Real results vary with the fridge and ambient temperature.
One larger unit is simpler and usually more efficient. Two smaller units add redundancy and flexibility but cost more per Wh and take more space.
