WattRunTime
Estimate how long your power station lasts
WattRunTime helps you estimate how long a portable power station can run a fridge, CPAP, Starlink, router, laptop, RV setup, camping kit, or outage essentials. It uses visible assumptions for watts, efficiency, reserve, duty cycle, and battery capacity, so the answer feels explainable instead of magical.

A battery may say 1024Wh, 1500W, or 1800W, but the real question is usually simpler: how long will it run my fridge, CPAP, Starlink, router, laptop, or camping setup? WattRunTime is built around that practical question. It estimates runtime with visible assumptions like efficiency, reserve, duty cycle, surge behavior, and device load. It also includes model data, scenario pages, surge checks, Starlink Mini runtime, and battery capacity conversion. The goal is not to promise perfect runtime. Real use depends on temperature, device settings, inverter losses, battery age, and load changes. The goal is to help people plan with better numbers before buying or relying on a power station during an outage. Would love feedback from campers, RV users, off-grid people, and anyone who has tried to calculate backup power by hand.
