    Great Portable Charger

    This charger is great - it is slim and portable and comes with a case which is nice. It charges up quickly, keeps a charge for a long time, and is very handy for charging my phone or earbuds away from home. I like that it has both USB ports and a C port which many of my devices have. A good solid portable charger.

    Great device, it charges very fast almost 1% per minute. Only downside is that it does not have usb type c output, but input only. Fastest charge battery pack I ever used for sure. Pros: Fast charge Two usb outputs Cons: No usb type c output

    Bought this power bank for disney world and worked great the only thing that I would changer about it is that it takes forever to charge. I even tried to use my 45w laptop charger and still took a while. But all in all a great charger.

    My only complaint is that it takes a long time to charge, but once charged, it powered both my wife and my iPhone for quite some time while we were travelling

    Great value and performance

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Outstanding value. Great brand. The only feature that I wish it had was that it could use the USB C connection for both charging and supplying power. As to performance, I ran a variety of tests with an instrument that measures voltage and current and it delivered what was promised.

      Thank you so much for sharing your experience. We're really sorry you've encountered this issue!

      In regards to efficiency, all our PowerCores burn 30-40% of their power when they are charging other devices.  So the PowerCore III 10K mAh USB-C Portable Battery Charger has 10,000mah of power, but the power left for charing your device is in fact 6,000 - 7,000mah. Please confirm whether the combined battery capacity of your 2 mobile phones exceeds 6,000 mAh.

      Please reach out to us via support@anker.com or call us at +1 (800) 988 7973. We are more than happy to assist you further.

      We offer an 18-month warranty for this product, plus lifetime technical support. Our standard for responding to email quests is less than 24 hours, and we look forward to hearing from you! anker

    Bought one, it didn't work. Returned and exchanged it for a second one. That one also didn't work. How did this happen? I used to have such a high opinion of you, anker.

      Thank you so much for sharing your experience. It's unusual for this product to be acting like this, and we'd love to get you what you need!

      If possible, please try the following steps to see if the issue persists:
      - To recharge the battery itself, try another wall charger, wall outlet, and cable
      - To charge another device, try another cable and try the power bank on another device

      If it doesn’t help, please reach out to us via support@anker.com or call us at +1 (800) 988 7973. We are more than happy to assist you further.

      We offer an 18-month warranty for this product, plus lifetime technical support. Our standard for responding to email quests is less than 24 hours, and we look forward to hearing from you! anker
