The thing that I would worry about when running the Eva-Dry from the battery is whether or not excessive voltage might harm the electronics. Not saying it would -- I have no idea one way or the other -- but since the Chinese cut the engineering specs so close it is something that I would worry about. My power supply has adjustable voltage, so I would run it at exactly 12 volts. Probably any American made unit would handle 13.6 volts quite nicely, but the Chinese are inscrutable.
I think that almost everyone has made the modification to drain into sinks, etc. There was a picture posted on an earlier thread about this, showing a tube stuck into the front of the receptacle which holds the water, and so a quick drill bit and a piece of unused stiff plastic tubing, and voila!
