About Kilohour
Free runtime calculator for portable power stations
Kilohour is a free web tool built around a single question: how many hours will a portable power station keep your gear running? Pick one of 52 models from EcoFlow, Jackery, BLUETTI, Anker SOLIX, Goal Zero and DJI, add devices from the list or enter your own wattage, and set how long it needs to last. You get cautious, typical and optimistic runtimes plus a verdict on whether the station can start the load at all, checking both continuous output and startup surge. Specs come from the makers' own product pages and manuals, each linked to its source with a last-checked date, and missing numbers are left blank rather than guessed. Also included: a sizing tool, a solar recharge calculator, a two-station comparison and CPAP / home-outage planners. Free, no account.
