I boiled nearly 1.5 liters of water in just over 6 minutes and when it was done it automatically shut off but kept boiling for a while

It brought 1.7 liters of water to boil in 7 minutes 17 seconds at near sea level

The first batch of water (about 1.6 liters) boiled in about 7 minutes

It will boil a liter of water in about 3 minutes (that's enough for a 6 cup french press).
