Nope...power (watts) is calculated by I*E. So 800 watts at 110/120 Volts is P/E=I 6.7Amps.
Now you take 6.7Amps x12Volts to get 80.4Watts DC.
Look up the specs on an 800W continous power invertor and you'll see that the maximum power draw is 6.9A DC (which takes into account conversion losses).
Now you take 6.7Amps x12Volts to get 80.4Watts DC.

Watts = Watts. Takes 800 Watts in to get 800 Watts out. Amps out is NOT the same as Amps in!
Power is Voltage x Current. Current is Power / Voltage.
Output = 800 Watts / 120VAC = 6.7 A Amps
Supply = 800 Watts / 12VDC = 66.7 Amps

this thread made me remember that I have an 800 watt inverter in my garage just collecting dust, lol
I may have to see if I can't hard-wire it in with a toggle switch maybe
2manytoyz, where in Cocoa are you at? I'm moving to Titusville this week
I grew up part of my life in Cocoa actually
