    I recieved my powerbank and charged it up. I used the fast charge port and it works great. The second Port is hit and miss. It makes little popping sounds when plugging into it with the USB. I believe there may be a short. I plan on contacting Anker about it.

    I wasn't aware one of the plugs takes a long time and one is a little faster. Not much on how it works or directions. Takes a long time to charge.

    Didn’t like how heavy it was and took awhile to charge my phone. So I bought a smaller one that works a lot better

      Awesome! Glad you were able to find what you were looking for. Usually we try to gauge ratings based on things that we can fix, but it does look like you were just looking for a different size. Is there any other reasons why this was two stars? Give us a call so that we can make sure we provide the best possible quality control we can - 800-988-7973 (9-5PST) anker

    This is great to have but it takes me ver a couple of hours to get a full charge. I guess I thought it would be faster than that

    Battery pack did not fast charge my S8+ but regular trickled charge. Charging battery was longer than expected

      This power bank does not have the fast charging technology your S8+ is looking for.

      You'd be looking at something like this:

    My IPhone 6S Plus is getting a little long in the tooth so it’s battery life is getting weaker. I decided to buy this to charge it when I’m not near a plug to keep my phone from dying. I used it 2 times while out and about and it did the job. I kept charging it every week to have ready when needed. The next time I went to use it I plug my phone to it and it appears to be charging. Then it stopped. I plugged this up to charge it and the blue charge lights never went past 1 light. I charged it for days!!! I should’ve bought the warranty or went with Mophie. Waste of money!
