    I'm always on my phone and my battery is always low after a few hours. This allows me to work without worrying about losing power.

    I had one before, and I lost it. The next day I went out and bought the same one. It’s a solid piece of tech! Great for outdoor hikes or concerts.

    Anker makes solid products, this is no exception. Stand by time is outstanding, I lost count of the charges I get after it is fully powered up.

    I have bought several of these for long trips and for my children’s devices. I do find that after a while of use that only one of the USB ports it works well. This is after a year or two of where in tear so it could really be from the abuse my children give it

    It's Anker - so it'[s great value. Best Buy did not have the latest, so I was stuck buying this with a Micro USB charging port, not USB C

    lemon?

    i bought this charger mainly because it had 2 usb connections and higher mAh. i wanted to be able to charge 2 iphones at the same time “quickly”. but, it turned out to be a lemon because the power button kept shutting off. in the few times that it did stay on, it would shut off when the usb was plugged in and it wouldnt turn back on. anker has received high reviews on some of their products, thats why i think i just got the lemon of the batch. ended up returning it since it was defective.

      We apologize that you had this experience. The light on the powerbank itself does not need to be on for it to be charging your devices. Check your device to make sure that it shows that it is indeed charging. anker

    Provides 2 day power for my Adobe Dot

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

    I needed to power an Adobe Dot that is in a location that is not near a power outlet. The Dot solves the problem. The only problem is that it takes so long to fully charge. That is probably due to the fact that it stores so much power and is only charged via a USB 2.0 connection
