I like the one that Bob recommended, but I would get the 500 watt model. You can save $9, but more importantly the wiring is too small for 750 watts. 500 watts is more than adequate for your needs and less chance of overheating the wiring.
You donít need an explanation, just plug it into a 12v
outlet, turn it on and you are all set.
Heck, this is such a nice model with great features for not much money, I think I will order one for my car and to use in our Airstream so I donít need to turn on the 2,000 watt inverter.
