Bests & Worsts Reviews from Amazon

This portable charger worked as described for two months and then it stopped working completely. I never over charged it and I used it sparingly. Now, it will not charge-up, turn on or charge any device. It has totally failed. I purchased two others in May and they also failed after a few months. This product appears to have a design flaw and lack quality control because the life expectancy is less than advertised. I rate it 1/2 star.
