Well this is a new 12ah battery , the old 7.2 was not much chop. Need to be continuously charged when not in use.

A laptop sucks up the power with all the USB connections and the screen.

I use an 18v 4-5 ah ryobi drill battery if I need to for the old Ubuntu laptop and even that does not last if not fully charged . MostLy use a cable.

My home made 12a cooler sucks the battery out in an hour so I Use the old battery off and on. The cooled camera is ok on the new battery with the heater and the mount for four hours but I think if I added a USB hub I would have to run that off the 5v connection on a drill battery as I have done before
