WattSized is a free, no-signup calculator for portable power stations. Check off the appliances you want to run — fridge, CPAP, sump pump, laptop — and it computes the watt-hours and surge watts you need, then recommends real models (Jackery, EcoFlow, Anker, Bluetti) that fit. Presets for storm prep, camping, van life, and medical backup.

Hey PH 👋 I built WattSized because every time I looked at portable power stations I got lost in watt-hours vs. surge watts vs. running watts — and it's really easy to buy the wrong size. So I made a calculator: check off what you want to run (fridge, CPAP, sump pump, laptop…), and it tells you the capacity and surge output you actually need, then shows real models that fit. No signup, brand-neutral. Would love feedback on the appliance list and the presets — what did I miss?
