“I’ve always used Booster PAC jump packs in my family business, my diesel business, and even have 2 on the farm. I recently updated one of my booster packs because of age, and I got the ES5000. Little did I know I was buying the most bad a$$ jump pack I was ever gonna own.
I knew it would have no problem starting cars, but on the way home from buying it, I got a call about a Volvo EC220DL excavator not starting. I had concluded the batteries were just too weak. So, with really no other options, I used the ES5000.
