    Trunk open. I'd be like a mobile TV service. Probably not a bad idea considering I get tailgated most places I go.

    for this load hardly any gas will be used there are numbers given by many who used the prius to power their houses during sandy for example

    Not suggesting you do this with the OEM Prius 12 volt battery, but I have fitted a mobility battery in place of the standard Prius 12 volt. This battery is rated at 62 AH (amp hours) against the OEM battery of 40 AH. This means I could run your TV for up to 10 hours without turning on (making ready) the car and still expect it to start.

    So this worked out great on Saturday. Powered the TV for about 4 hours, charged some phones and fired up a blender a few times for some margaritas. People were impressed. All while using about 30 cents worth of gas according to the display. Possibilities seem endless. I wonder why they haven't included outlets in the trunk area?

    Prius, the ultimate tailgating accessory. lol.

    Well you are not the only one asked this question ... as a matter of fact in Japan there is now an option to include an inverter to power the house... (installed one mayself for emergency purposes.. the inverter is not in the car but the conncetion with fuse is)

    You seem to be the only one I've seen so far that's voted against connecting an inverter to the 12v battery. Can you elaborate as to why other than because you think its too small?

    I think what he meant "I would never attach an inverter directly to the Prius 12v battery ALONE" so then goes the two other batteries ...... but lets hear from him :)

    I would be just worried if the two batteries have way different SOC (namely low) from original Prius battery this could create issues at least when the car is not in Ready Mode... they could all discharge each other

    Ahhh, gotcha. Are you using the 3kw inverter for this configuration? I've been reading a thread that 12v source is good for only around 1500 and that if you want to go higher you need to connect directly to the hybrid battery.

    Well the DC/DC converter is probably a lot better up to the nominal max load I think 150A fuse (but that is probably not sustainable).

    No moving part to begin with and doesn't rely on belt driven by an idling engine ....

    Well he must fuse it properly on the 12V side, I would not go over 100A ....

    For sure with the 3KW inverter it is possible to burn the fuse of the DC/DC converter which would not pleasant (car is dead no 12V bus )... but the 3KW inverter with the cranking power of the, now three battery, may very well help in rush-in current, situation for short term ...

    lol...Do you keep your marine batteries in the car already connected or just throw them in when you need them?

    Thanks. Just so I can picture this, do you just wire them in parallel directly to the 12v battery?

    I'm more concerned with hooking up a refer or window AC unit.
