I'm going on a 3 or 4 day camping trip and I've been looking at some portable power options. I don't want to have to leave the car running in order to have power (through an inverter) so I'm thinking the best option would be to get a portable battery/jump starter such as this:

I've never used one of these so I'm curious about how long this will last me before having to recharge it again. Now I'm sure it depends on what I have hooked up to it and how much power it's drawing so is there any way to calculate how long this battery will power a specific device based on the devices specs?
