I have a 1500 watt pure sine inverter in my car and it's the second car with an inverter. Never had a problem running a 2 drawer HP laser printer off the inverter. The HP is a 350 watt printer. That's what you have to be careful of the printer takes 3 times power to boot up so the inverter must have enough power to turn it on. Never had a problem with electrical system. Just DON"T turn off engine while inverter is still on. |
