Why buy expensive jumper cables?
Buy more expensive jumper cables for this simple reason: You want the other car to start. Cheap jumper cables are a bad investment. They’re made with thin 10-gauge wire and cheap clamps. You want a thick (4- or 6-gauge) wire to move the most juice when you jump start a car.
High-quality cables (such as the Hopkins BC0860 shown; about $40; available through our affiliation with amazon.com) have professional-grade clamps that won’t pop off. High-quality cables are a once-in-a-lifetime investment. They’re priced according to wire gauge, length, clamp quality and the ability of the insulation to flex at minus 30 degrees F.
