What is the difference between 4-Gauge and 2-Gauge?
I am wondering whether to get 2-Gauge jumper cables or 4-Gauge cables to keep in my car. What the heck is the difference? Which one is best? Just in case you need to know.... I have a PT Cruiser.

For wire gauge sizing, the lower the number the thicker the wire. The thicker the wire, the more electricity can be transferred to your battery. A 2 gauge wire will handle about 25% more than 4 gauge. 4 gauge would be enough for most standard passenger cars, but having a thicker set of cables will never hurt.

Larger gauge wire can carry a higher amperage load. 4 gauge is perfectly fine for most cars, like your PT Cruiser. Jump starting a diesel, for example, might require a heavier set because of the much higher compression ratio in diesel engines(more amps drawn by the starter because it's harder to overcome the high compression ratio) and the fact that most diesels have 2 batteries.
