Customers are saying

Customers love the 20800 mAh Portable Charger's amazing battery life and attractive price. Its multiple USB ports and ease of use are also frequently praised, making it great for travel. However, some find it a bit large and heavy. The charger's capacity and overall performance are generally well-received.

    Does what at it is suppose to do at a reasonable price. A little big, but that is expected for such a battery.

    I am pleased so far. The only thing is, because of the capacity it takes a long time to charge. I also like the fact you can power multiple devices at a time!

    Don't Buy This

    I had checked the ratings for this device before buying it, and seeing the four star rating I figured it would be a good buy. However, it was not. I got it home, and it worked incredibly well for a week, but after that it would not charge my phone, and would die after 5 minutes of me trying to use it. DO NOT BUY THIS!!!!

    They Don't Work

    I bought three for my family. One hadn't moved from three boxes of charge to four after over an hour plugged in to a high-capacity USB charger. Another had moved my son's iPhone from 15% to 18% charge after over an hour. These things don't work.

    It will not charge anything anymore. I have tried different devices and cords and nothing. I am going to go back for an exchange since I do see a lot of positive reviews.
