Your fridge, your phones, your lights, your medical devices, your information: all of it assumes the wall socket works. The average US outage is measured in hours, but the ones that matter are measured in days.

A portable power station is a big battery with outlets, no fumes, no noise, safe indoors. Our primary pick is the Jackery Explorer: the default recommendation for a reason, with solar input so you can recharge without the grid. The serious alternative is the Goal Zero Yeti, born in the overland world, expandable and rugged.
When cell towers fail, a weather radio with hand-crank charging keeps you informed with zero grid dependence. Power keeps you comfortable. Information keeps you safe.
