Lithium Ion Battery Jump Starters

Anyone had a look at the "Rescue Mate" jump starter? http://www.rescue-mate.com
This uses capacitors instead of lithium batteries, and charges from the residual power still in the car battery.

It always started, but since they regain voltage as they heat up, I often had to short crank it 3-4 times to let the battery heat before it would actually turn it fast enough to start.

Hmm, interesting, never thought about warming it up that way

I've seen videos online about it. Seems like a brilliant idea for those in cold climates. Realistically I can bring my jumper inside with me during the winter when I'm at work or over night, but it is a hassle and the capacitor solution would allow you to leave it in your car all winter until you need it

Let's see if this works. EDIT: Photobucket's back I guess

It was starting a 12.5-1 G13 with about 250 psi craking pressure
