Mr.

This power bank charges extremely quickly and discharges to my devices moderately quickly. The only thing I was disappointed by was the fact that while every power bank I've ever purchased in the past came with at least 75% of a full battery but this one had no charge stored at all. I was especially disappointed because I made this purchase because of the fact that my phone was dead and I had nowhere to charge it, so when I plugged it into my phone for the first time and discovered that it had no charge you can imagine my frustration. That said, it's performance after I was able to get it plugged in and charged up has made up for that initial let down 5x over!!

Good does the job. I feel like they are scamming me into leaving this review though which is so annoying. In order to “ register my product for warranty” I have to fill this out. Bad move.
