    Worked fine till 60% charge was left on it. Then suddenly it dropped to 34, in a few seconds 22 and then 0. This is first time i have used it full cycle. I will try a couple more time and then return it if it keeps doing it.

    Worked for one day then it died. It was at 83 percent then cut of, wouldn't power on or charge. Wouldn't recommend especially with best buys 14 day return policy its highly likely it will die after that window and you're stuck with it.

    Failed after two uses while we were on vacation in Italy. Because I purchased well in advance of our trip BB was unable to provide a replacement. The manufacturer ignored my requests for warranty replacement.j

    Does not fully charge all my devices also seems to be very warm. I didn't know I needed a adapter which might help but was not told that and the package said adapter not included. Try to find what adapter I needed online and got nowhere.

    This product only worked for 1 day. After fully charging it to 100%, it immediately dropped to 87% battery life and then turned off. I could not get it to turn back on. Unsure if this was defective device but would not recommend.

    Multiple purchases of this item, and every one of them does not work. Best Buy also didn’t allow me to return the first purchase (used/failed//returned under 20days). Energizer also has been complete failure in customer service.

    This device worked good for about 6-8 months, then the power indicator stop working and it no longer powers anything. What a major disappointment as it was on sale and the specifications looked good.

    Received it August 25 and it stopped working today. It had over 80% remaining power as of last night. Maybe I just happened to get a bad one, and that's not normal.

    Bought this during a trip because of the plan of visiting Disney. Having only used it around 5 times, the power button on side stops working. So it no longer shows anything (percentage) when it is pressed.
