    I bought this power bank for a day at Disneyland for my granddaughter's 5th birthday. We were there for 13 hours and took tons of pictures. This power bank saved the day. Used it off and on during the day and my iphone was always charged. Shared it with my sister also. There was still power to spare on the power bank itself. I highly recommend it.

    Just purchased it and haven't had a chance to really use it, but from my research into portable battery packs this one will exceed my needs. I sell at arts and craft fairs and need to recharge my phone (iPhone) at least once a day to accept payments. At a $30 price it didn't put a strain on my budget.

    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.

    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.
