Bought the GB40 and charged it up. Then today which is about a month since I had charged my Ford Explorer was totally dead couldn’t even get the key fob to unlock the door. I had an older Duracell jump box that had been charging for the last week which is three or four years old but like I said I had just charged it and it would not start the SUV it just made a clicking sound when I pushed the start button so I went in and got my Noco GB40 hooked it up turned it on and waited about sixty seconds and pressed the start button and it fired right up. I did notice that the GB 40 was one battery bar down after using it. So I. Curious to see how long it will hold a charge but so far so good.
