Portable induction cooktop: how much battery you need
Portable induction cooktop draws about 1500 W (1200–1800 W range), runs 70% of the time and uses 788 Wh per day. Start-up surge: 1800 W.
Induction is the most efficient way to cook on a battery; turn it down after boiling. Champion lists 1200–1800 W running; we use the middle for energy and the top starting figure (1800 W) for the peak.
