I bought a Harbor Freight Jump Pack last spring. I got it mainly to power my ham radio when I set up portable but it works better than I expected. I have jumped several cars with it.
It is not a heavy duty unit don't expect it to turn over your diesel pick-up at 20 below zero. It is ok for most light duty jumps. I used it yesterday to get a v-8 Dodge truck going after we replaced the fuel pump. My neighbor had run the battery down trying to restart it. Here is a link to see one like it. I got it for about $35.00 with a coupon.
