    I just recently purchased this item for traveling purposes. I’m a little confused on how this item works. I used this on my iPhone and now on my Mom’s Samsung Smartphone. It’s working so far but what I’m confused there’s only one bright light showing while it’s charging my Mom’s Smartphone. Is that normal? Does it depends on each current battery life will actually gets charged? How long does the charging process for each devices separately?

    I bought this for my 13 year old son as a Christmas present. So far works great. Have not used too often yet. It is a bit heavy and bigger than most but seems to charge many devices well

    Gives my iPad Air at least 20% extra battery which is really surprising! It charges my iPhone to 50% so not bad for the price you pay. Also the USB C works to charge in/out

    It’s good power bank. But needs to be charge 15hours for me to get it fully charge. But it can charge my phone say 5-6x so it’s still good.
