Best OverallThe best-selling pre-packed car kit — cables, light, first aid, and basic tools in one bag — and the right base to build a winter kit on.

Twenty feet of 4-gauge cable that stays flexible in the cold and reaches a battery when the donor car can't park nose-to-nose — the cables to replace the thin ones in your kit.

The Lifeline kit includes jumper cables, so why buy the Cartmans? Because the kit's cables are thin and short, and they won't start a cold V6 from a donor car. The Lifeline is the right foundation — light, first aid, tools, a bag; the Cartman set is the upgrade that makes the 'jump' part of the kit actually work. Most people should buy the kit first and swap the cables.
Pick the Lifeline if…
- ✓You have nothing in the car yet — start here
- ✓Light, first aid, and tools in one bag matter
- ✓Four-cylinder car in a mild climate (the kit cables may suffice)
Pick the Cartman if…
- ✓V6, V8, or cold winters
- ✓You already have a kit with toy cables
- ✓You want to be able to help someone else
