cold temperture and the EX-3

[Geoff Mckay]

I was wondering if I could use something like an “eliminator’ to power my EX3. It is basically just a car batter, with jumper cables and an inverter. People use it to jump there cars in an emergency, or run a lamp, small t.v. or other appliance. I am worried about messing up my camera with low voltage, amperage, etc. Anybody every try something like this?
