the single power button will have all the control for the flash light, emergency light and output voltage switch, which is a bit confuse to use. Otherwise it is a good product.

Dear Ken, Thank you for writing us. If you have any questions, please let us know. Have a good day.

I gave this a 1 star rating before because the capacity is not what is advertised. That said, it does charge a phone pretty much completely or can charge about 1/2 of a very small laptop. I had the opportunity to try jumping a Toyota minivan with it, and it worked fine. As it does work for it's primary purpose, I have increased this to a 3 star rating. The secondary purpose of a backup battery pack for my laptop meets the minimum standard of extending the time I can use by several hours, but only by about a half charge. PrimeCables and 123Ink, as always (I must have made over 50 purchases from them), provides great customer service, so my complaints are not with them.

Center LED had scratches on the reflector & 2 outside LEDs did not work. The compass had an air bubble inside causing inaccurate readings. Recharging my laptop depleted the Battery Booster completely. Did not test the Jump Start capability. Returned for exchange.

Dear customer, We are sorry for the inconvenience. We hope the replacement was in working condition. Have a good day.

the case is too big to fit in my glove box, looks really messy for all the cable without the case, had to return it and hope they will come out with a maller one in the future.
