    A nice lightweight external battery pack. Our phones and devices are constantly running low so this comes in handy. Get 2 because one always seems to disappear...

    This has a huge capacity, and charges devices fast! The only issue is that it take forever to charge as the engery transfer rate is slow.

    Bought this as a gift for my sister's boyfriend to use while he is on the road all day listening to music. He says it works great to keep his ear buds charged 8-10 hours a day.

    Regular power banks usually can store enough power to fully charge a smartphone from zero to full about 2 times over.

    Being able to charge more than one device is what makes this ideal and the price is right! The charge holds for more than a day, just plug up and your charged in no time!

    Works great. Have used it a few times when my iPhone battery went down too low. Charges up fast and holds enough of a reserve to have for later uses.

    I can leave my house without it, I can plug my phone and my ipad at the same time. It allows many charges, and its easy to carry, maybe a little it heavy.

    So this should have plenty of power. It seems like a good value since it gives more power than most for a reasonable price. I should be able to use this for years to come.
