Best coolers to save your food in a power outage (2026)
FoodSafety.gov says a refrigerator keeps food safe for up to 4 hours in a power outage, and a full freezer for about 48 hours (24 if half full) with the door closed. After that, a cooler with ice keeps perishables safe. Here are good options compared.

Before you buy
Size it to your fridge: 70 quarts holds a typical fridge's perishables.
Ice retention claims are measured in ideal conditions; keep the cooler in shade and open it as little as possible.
Freeze water bottles before a storm: they keep the cooler cold and become drinking water.
Use an appliance thermometer
FoodSafety.gov says frozen food can be refrozen if it still has ice crystals or is at 40°F or below.
We verify every product's specifications against at least two independent sources, re-check its US price and stock on a schedule where we can track it automatically, and cross-check safety-relevant claims against official guidance. Every review is labelled Researched or Used and reviewed by us: where we've bought a product, or been sent it free, and used it ourselves, its review says which; where we haven't, our verdict is a considered spec-and-evidence comparison, not a hands-on test — and commissions never change a ranking either way.
