Re: A New Electric Vehicle (Long)

Anywhere.

I have a few 5600 BTW window AC units that are in my house. Pulls 490 watts
at 110 volts, with an EER of 12. Nice little Sears unit.

I can (and have) run these off my shed's APC 1000 watt converted UPS
inverter no problem (300amp/hrs behind it at 24 volts).
