Understanding watt-hours will help you survive power outages and off-grid adventures.

The watt-hour is a measure of capacity, or how much electrical energy a battery stores.

During a blackout, you’d need about $15,000 worth of batteries on hand to keep it running for just one day .

EcoFlow Delta Pro 3 solar generator has 8kWh of total battery capacity.

Homes can be fitted with solar roofs and fully integrated battery backup systems from companies like Tesla , Jackery, EcoFlow , Anker , Bluetti , and others.

Otherwise, you can always keep it cheap and old school by firing up the ol’ diesel generator.
