    Stopped working a few hours after purchase. Maybe it's worth it to spend more for a better power bank.

    If I could give this a zero, I would. This thing will charge up; but it doesn't continue charging anything you plug into it. Didn't realize it until after the return policy had expired, so I'm out the $100 I spent on two of them. Totally worthless. Don't waste your time or money on them. Thought the brand name would be worth it -- wrong. From now on, I'll stick with the no name battery packs that cost a fraction of the price and actually work.

    This charger in less then one month after purchasing. Stopped functioning properly stop lighting up. So you could not tell if it’s powering your cell phone. I first I thought it completely died. It still charges but this product turned out to be very disappointing considering the manufacturer is Enigizer. Buyer beware. .

    I received the charger with 3 solid lights on the battery indicator, which means it's 50~74% charged. I used it to charge my Samsung Galaxy by a mere 30% and the battery has completely died.

    Didn't work out of the box for wireless charging. Instructions should be obvious, but the included instructions were garbage and on line videos were about as helpful as not watching them at all. I'm hoping that I got a bum unit - took it back and replaced it with the 10,000mAh unit as they didn't have any more 20,000. Meh.

    This item worked for three months and I have been unable to get a replacement or refund from either Best Buy or the energizer company. I do not believe that the two-year warranty on this item is real.

    Great portable charger that I can easily carry in my purse or bag. Generally, it carries a charge for a day at a time. I would recommend this product, especially for the price.
