I never did use the device to re-start a car, but after it sat for a while and I decided to top off the device...I discovered that it will not re-charge. My wife bought two of them at christmas. Neither would recharge, despite a very careful reading of the instructions. Makes lots of beep sounds but nothing works correctly. I then went onto the web and discovered MANY others with the same experience. I am amazed that Black & Decker still has the device on the market. It does not reflect good brand quality.
