This question has been asked a hundred times, I'm sure. I would like to install a inverter?charger?, where if your hooked to 120 the 12 volt accessories are running off of the inverter and it is charging the 12 volt battery. What are they called? How hard are they to install? I have a mid priced charger from wally world, but if you draw power from the battery while charging it kicks the charger off.
Thanks
