Review on 🔋 DEWALT DXAE20VBB 20V MAX Automotive Battery Booster and Jump Starter with USB Power Station: Compatible with FLEXVOLT and Standard Tool Batteries by Bobby Frazier

This charger/jumper was great. I think most of the bad reviews are from people using 5 amp batteries or less. Use this with a 6 amp or 9 amp flexvolt and it works amazing. As most people have commented this will not jump from a dead and worn out battery due to an internal safety circuit.
