Power Station Sizing Calculator
Two numbers matter: watt-hours (how long) and watts (how much at once). This tool sizes both.
Power Station Sizing Calculator
Pick your devices and hours; we do the arithmetic and show only stations that cover the load.
Runtime = capacity (Wh) × efficiency ÷ load (W). We assume 85% efficiency as a planning figure (yours may differ). Device wattages are typical planning values you can edit; check your own labels. Capacity and output for each station come from its product page.
