Wh × 0.85 ÷ (watts + the station’s own draw, where the maker lists it).
A heater turns electricity straight into heat, so its draw stays high the whole time.
How much one use takes
Ten minutes at 1,500 W uses about 250 Wh, about 14% of the DELTA 3 Max Plus’s usable 1,741 Wh.
The CPSC says never to power a heater with an extension cord or power strip, and never to leave one running unattended or while you sleep. Heater makers say to plug into a wall outlet; check your heater’s manual before using a power station.
