Check price on AmazonHow we calculate it
Runtime = capacity (Wh) × 0.85 ÷ 400 W
For three loads of laundry you need about 1,420 Wh (1,200 Wh of energy plus inverter losses). Running other devices at the same time? Add them in the runtime calculator.
Tips to run your washing machine longer
- Use cold water: front-loaders with a built-in heater can draw 1,500–2,000 W while heating water.
- The motor needs a short start-up surge (around 1,200 W) and up to ~500 W during the spin cycle.
- An electric dryer (5,000 W+, 240 V) is out of reach for portable power stations. Line-dry instead.
