    Picked up this power bank and it has been better than expected. I've been charging cellphones, ipads and even a MacBook. Being able to charge a device to it's full capacity and still have room for way more is a plus. Only draw back is the time it take to fully charge, but once it's charge you're good for many charges.

    PORTABLE power for devices at a 10hr festival sale. With no power outlets and using 5 phones and 1 tablet to handle active product sales on a Point of Sale app, these portable chargers with 2 USB A ports combined with 2 tri-type charging cords handled continuous use by the POWER HUNGRY P.O.S app.

    The power bank that you need for your travel! Charged by phone 3 times from 10% to 100% and the power bank still had more than 50%! I would definitely recommend this if you’re planning on using your phone for taking photos and videos since the phone’s battery will be consumed faster. Definitely a must-have for your trips.

    I am very pleased with my purchase of this battery charger. I purchased it before a three week trip and in which I used it for two weeks before having to plug it back up to recharge. I highly recommend this product because it exceeded my expectations.

    I took the Anker portable battery charger on a recent trip overseas and used it repeatedly. It kept our phones charged as we wandered around throughout the days, using up the power on our phones with digital maps and guides. So helpful to have!

    Purchased this for an international trip to keep our phone charged in between layovers and it worked well! It's also fast charging compatible which was nice. It did take some time to charge the powerbank fully but really no complaints. It functions exactly like it should.

    This works great! I took it to a three-day convention and it kept my phone working through long days when I didn't have access to a wall charger. Very happy with this device as I have been happy with my Anker USB Hub and my Anker plug-in USB chargers.

    I purchased this charger after reading the reviews from others, and I am happy to say that this little charger is fantastic. The sleek design and the length of the charging cable is what sold me. I have used this a few times and I am very happy with it...

    Bought this portable battery charger to take with us on a road trip where we had 2 tweens with tablets in the vehicle with us. This unit worked just fine to keep the backseat riders 'powered up'.

    So far, so good. My previous charger lost it’s charged just sitting in a drawer. I charged this one up a week ago and, in the same circumstance of sitting in a drawer, it is holding the charge at the same high level. Which it should! But the other one didn’t.
