Useful places to start

What should my household do first during an outage? A private, fixed-choice plan for the household systems an outage can disrupt. How much water should I store? A drinking and cooking baseline, confirmed extra water, container capacity, and filled weight. Is my fridge or freezer food still usable? A refrigerator/freezer timeline that hands off from elapsed time to temperature evidence. How long will my battery last? Runtime from constant watts or measured 24-hour energy, with a separate running-output check.

Start with the appliances and circuits you actually plan to support. Check their running and starting requirements, required voltage, and the time you may need to operate them. Capacity in watt-hours and output in watts answer different questions; neither replaces those checks.

The listed specifications do not establish real-world runtime, suitability for a particular medical or critical device, current price, or availability. Check exact-model documentation and applicable safety instructions.
