About Kilohour
Kilohour is a free portable power station runtime calculator. Pick EcoFlow, Anker SOLIX, BLUETTI, Jackery, DJI or Goal Zero models, add fridge/CPAP/laptop loads, and get a cautious-typical-optimistic runtime range based on sourced specs.
Kilohour helps homeowners, campers, and RV travelers estimate how long a portable power station will run real appliances during an outage or off-grid trip. Instead of a single optimistic Wh divided by watts number, it applies usable battery capacity, inverter efficiency, idle draw, and duty cycles, then returns a runtime range. The free calculator covers dozens of current models with manufacturer-sourced specs and publishes every formula on its methodology page. Use it to size a station for a fridge, CPAP, laptop, or camping load list before you buy or before the next storm.
