What size generator or power station for an electric lawn mower? (1,900+ W)

To run an electric lawn mower, choose at least
1,900 W running · 2,500 W startup surge.

An electric lawn mower draws about 1,500 W while running, but its motor can spike to roughly 2,500 W at startup, so size for the surge. Pick a generator, inverter or power station rated comfortably above these numbers.
