Electric kettle 2 kW: how much battery you need
Electric kettle 2 kW draws about 2000 W (1500–2400 W range), runs 100% of the time and uses 400 Wh per day. Start-up surge: 2000 W.
One litre boil ≈ 100 Wh; the problem is the 2 kW draw, not the energy. A 1 kW travel kettle or a gas stove is the outage answer.
