Since the 12v products are naturally battery hogs; The best bet is to use a couple of deep-cycle batteries and an inverter with enough power to run whatever 115vac appliance you want, most are about 1500-1750 watts. It's not a perfect system either but it works better than straight 12v. I use a 2200watt inverter to periodically run a 700Watt microwave and a toaster and the batteries (series 31 deep cycle) hold up well for a normal weekends periodic useage, if at a camp ground, I have an onboard battery charger that can be plugged in overnight to help recharge both batteries. I would recommend a: off/1/2/both battery switch and a high current in-line fuse.
Why hasn't anyone found a dead bigfoot? When was the last time you found a dead deer, bear, coyote, fox, squirrel, etc. that died in the woods.........Hmmm.
