    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!

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

    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.

    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.

    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.

    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.

    A little slower recharging than others I've used. Requires a charge after each use.

    Really glad I bought this. It’s a life saver when you are on the go, and it’s very powerful. The usb-c is very useful for charging my MacBook when I have no outlet.
