It's hard to recommend a product that tries to be a multi tool. Don't expect the air compressor to last long but the jump pack is perfect.

My old truck runs great but one time this past summer I was tailgating at the beach watching the sunset, running the radio but not the engine. And I wore the old battery down to the point that when I was all packed up and ready to go, my car wouldn't start. I had to call for battery service and wait for 2 hours in the dark for the guy to arrive. Well that will never happen again now that I have this emergency car battery charger. It also fills tires. You can set the exact pressure and it stops when it gets there. Comes in a nice carrying case. Everyone should have one of these in the car for emergencies.
