    It works but the first time I used it it went from 47% to 0% really quickly. Hopefully that was a fluke.

    I got this charger few weeks ago. Although I don’t use regularly but keep this ready for any power outage situation. Specially during this winter. I like the display feature.

    I hope this was just a defective one from the start. I couldn't get it to charge all the way, it got very hot when charging and then wouldn't turn on. I'm taking it back today.

    Took a very long time to get to 100% charge when initially plugging it in. The Energizer died surprisingly quick after that and continues to act the same way.

    Right out of the box it started having problems. It was stuck on 86 and wouldn't charge past that. I found a reddit thread about the issue that instructed me to use the battery down to 50 and try to charge it up again. Well that worked. But then it would flash "188" every once in a while. Didn't trust it for its purpose so I returned it promptly.

    This power bank is ok. I feel like it is a lil weak. It worked ok for my needs, but I don't see this as something I'd repurchase.
