    Works well, has 4 ports. I Like how you can charge battery pack and charge devices at sme time. Simple to operate it however it could hold more charge. Maybe could've got the battery pack with twice the charge

    Solid and well built charger . Bought due to possible power outage. Did not loose power ,but was ready . Subsequently at leat now I am ready ,Just In Case. Seems to be a quality product , but a bit large, Guess that is a good thing for a back up battery.

    It charges everything that I need it to. I didn't read the directions so I was confused when I tried to turn it off. For all those who throw out the directions before operation, it's two clicks to turn off and one to turn on.

    It didn't charge when I first bought it. I tried different charger and still it only has two bars, the third bar just flicker but doesn't charge. I went to Best Buy to exchange, I couldn't due to their policy. This is the second one I bought and would not recommend. :( I tried explaining that to one of their representatives but they know better...

    Only used it once so far and it worked as advertised. It did take a little longer than I expected to charge my phone, and it used up most of it's charge doing so, but it did work.

    This portable battery is strong enough to charge 2 phones, which are used continuously either for GPS navigation or for internet surfing. However, it is totally empty at the end of the day and has to be filled again.

    Good product. Takes a while to fully charge. But, will give plenty of charges to your devices when needed. And it can charge a tablet with several charges to spare.

    Very handy and capable when I need to bring extra charge someplace where I don't know if I will have electrical access. minus one star because it is kind of heavy for its size.

    I love how this charger can be recharged faster by USB-C! But the only one flaw is that it cannot be discharged using the USB-C port! But other than that, it’s a GREAT charger and one that I would get again!

    I like the charger very much. There is one thing I would like to see is how much is left on the charger in percent instead of lights. Really came in handy during the power outage.
