    Slow charging my phone and even slower to recharge the unit itself. Stuck with it since I was a week over Best Buy’s 1 week return period.. Found a $20 off brand on Amazon that works better.

    This charger works as it should but the problem is. Housing in a soft breaks apart when it falls on the floor by accident. I have this happen too many times to the point that I have to take it apart. And I could not fix the charging circuit. I have to shower shave battery. And build a new charger. From it

    I am not enjoying this purchase, It is large and heavy and it doesn't charge as quickly as I was told by the associate at the store. It is not user friendly, I do not know when it is off or on.

    This product doesn’t worth the money I paid, just last one month and didn’t charged my phone anymore. Inside the package I found a warranty Email from Energized and I sent them a message and they never answer me back. I’m not recommended to buy this product to nobody.

    Horrible product. I purchased this power bank to recharge my Go Pro while on vacation. The device would not recharge or take charge to restore battery. I took it back to Best Buy and the will not take it back. I had missed the 14 day return by one day. I have been a Best Buy for over 30 years. I will no longer patronize their business anymore.

    Once fully charged and not plugged into any device, it continues to discharge/lose power over 2-3 weeks until it's fully empty. I've contacted Energizer and they have not addressed the issue. Seems like a major defect. No other power bank that I have loses it's charge like this.
