Wire size wire for...4 Ice chrgrs-20 feet from 12v battery

I have power supplies for normal use but I was going to be at a remote location. Sand dunes to be exact. Me and my kids are pretty much all set. I was hoping to pit at the back of the vehicle with the chargers inside the vehicle to keep the yahoos from getting sand in my equipment with their quads. Maybe I'll try to stick to 1 or 2 chargers. Can I run the vehicle while charging with the Ice chargers? I assumed that would be too much voltage.

Just check the manual. Input voltage is from 11-15 volts so to answer my own question. Yes.

Actually, I didn't mean "power supply" as in a "power supply unit", but rather a "supply of power". Sorry about the confusion! :)

Most, if not all, of these ~12v input chargers seem to have vehicle use in mind. That's why (among other reasons) they use the 11-15v range, so yes, they can be run in a vehicle, but you've already answered your question.
