Power consumption for A1 printer

Why on 220Vac the power consumption is 4 times more than 110Vac ? Power should be close to the same, no matter the AC voltage supplied

It’s simply Ohm’s law…

The bed heater resistance remains the same with both voltages.

@lkraus

Ohms law at work.
P=V*I is the same as P=V²/R
The bed resistance is the same, so doubling the voltage quadruples the power usage of the heat bed.
