I don't recall the last time I needed to use them, but I always carry a
set. I bet you do now too. You can get them for as little at $10.

Thank you everyone.
I will get 6 gauge or 4 gauge or even smaller (lower numbers being better
especially for longer distances).

I found a lot to choose from at home depot online

Not so many at Lowes online and much higher prices

What LENGTH is a good compromise between packing in the trunk & usefulness?
10 feet?
12 feet?
16 feet?
I'm kind of leaning toward buying three sets, one for each car.
