Review on 25 Foot EPAuto Heavy Duty Jumper Cable For Boosting Vehicles - 1 Gauge, 800A Capacity, Includes Safety Gloves And Carry Bag by Christopher Kumar

These are great. I bought two sets, one for each car. I went with the 4 gauge because I know the lower the gauge, the heavier the wire, and I wanted good strong cables, but I must say I probably went overboard with not only the gauge but the length; the package (the cables, rolled up, in their round plastic bag) is quite heavy and takes up a fair amount of space; not an issue if you have a big car and trunk (or room under the seat) but one of these sets is for a Miata with a trunk that barely holds a couple bags of groceries, so I'm trading one of these pair for a shorter, lighter gauge pair. Neither the gauge nor the length is a fault of the cables, they offer plenty of options. But give some thought to both the gauge you need (12 is probably the most common) and the length (12-16' might make more sense). You want your cables to be long enough to reach from one car's battery to the other car's battery, even if the batteries are on opposite sides, but you don't want the cables to be so long that you don't have room to store them.
