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

I bought these because my wife mentioned her frustration with not having jumper cables when someone she encountered needed help. I bought these on revain to keep in her car. About a couple of weeks later my mother in law called with a dead battery; she had spent the night over at my daughter's house and left the lights on over night. Long story short, I drove there and saved day for her. The way I had to park my battery was on the opposite side of my vehicle. They reached easily. I didn't need to crank my truck. I felt good about the 4 gauge. For people that don't know, the smaller the number (4 gauge vs 6 gauge) the larger the wire conductor, resulting in less voltage drop.
