This is a great powerful jump starter. It's very handy to have and easy to use.
I helped a stranded motorist waiting for the CAA to boost his car dead battery in cold damped weather. The GB40 boosted the dead battery and started the engine immediately. I would have given the GB40 a 5star rating. However, there's a design flaw with the booster cable connector. When this connector is connected to the 12V OUT of the jump starter Lithium battery, it's very easy for the cable to become dislodge since there's no locking mechanism to secure its connection. NOCO, please include a connector locking mechanism in the new design and provide a free retrofit kit for present owners.
