My Noco has been gong well since 2019. It’s jumped my diesel BMW X5 many times, a friends 1 ton GMC, many other vehicles I have jumped, and I tested it on my Jeep……luckily the Jeep has not lest me down yet.
My only issue is the GB40 can go dead over time. Good news it it charges reasonably fast off the rear power port. So I check it periodically, and charge it on occasion. FYI ALL JUMP BOXES will drop charge over time.
