Great Product!

Simply put, I bought this lithium jump starter about a year and a half ago; charged it up and put it in the back seat of my Lexus RX "just in case." Then, sure enough one day the RX wouldn't quite start, I followed the simple directions, connected it to the car battery, got back inside and voila! the car started! Used it two more times on a friend's car, never a problem. Now, however I have somehow lost the USB charging cable and the ones I have for my phone and Kindle simply don't fit the GB40, so I have ordered a replacement cable. No reflection on the GB; it was my fault to lose the cable. A happy customer!

Yes, I recommend this product.
