So I went to the auto parts store today for something, and asked about wire gauge for jumper cables. The guy told me that 4 gauge wire was the best, because it gives a better connection. Their cables were $25.

At Wal mart the other day, I saw some in a small package that were 10 gauge wire for under $6.

Is there really that much of a difference? The WM cables were in a small compact bag, ideal for the car kit.

Do you think the 10 cables (12ft) would work well?
