I bought this in 2019 when I had a truck then in July I bought a new car. I used the jumper a couple times on my 99 Yukon before I bought the 2016 Jetta. I helped a few other people with it. The original cord is lost but it changes just fine with the one that's on it now. I tried to charge it up today 10-26-25 before posting but it's been holding a full charge since August. Firm is price. I paid like $200 for it.
