Jumper Cable Gauge Sizes

Q: Recently I was looking to buy jumper cables online. What is the difference between 4 gauge and 10 gauge?

A: The gauge is the size of the wire. The lower the gauge number, the larger the diameter of wire. The lower gauge (larger wire) jumper cables are more expensive, but more electrical current can flow through them. They also stay more flexible in cold temperatures, which make them easier to use. I would recommend that you buy 4 gauge jumper cables.
