Just read this article: The power of the Prius - Local - The Moose Jaw Times Herald Could this be done with a non plug-in Prius? How does it work? When the 12v battery is depleated the car in Stan By mode will start the ICE to recharge?
yes, keep the car in 'ready' mode, (outside) and it will run for days on a full tank of gas, keeping the 12v charged. just keep your eye on it so no one will steal it.
This is about as large as the 12 volt converter in the Prius would power. 1250 Watt Power Inverter 12 Volt by AIMS 800 Watts might be more sensible, but I could not find one as full featured 800 Watt Power Inverter with cables by AIMS For larger loads, you would need to connect to the 201 volt (varies by model of Prius) Battery.
