      Hi!

      I am sorry to read that the portable charger didn't work as expected. My advice would be to make sure that the cable that you are using to charge your iPhone device is compatible with it. If you have questions about this product, please contact us on the link below and we will gladly check the specifications of the unit.

    Great battery. It holds a lot of juice but that also makes it pretty heavy. Get it if you need to charge often or for a long time.

    Excellent charger , had it connected to 2 phones and portable blue tooth speaker and it keep everything charge up and going all day. The only thing that I did not like was that came with really short and flimsy charging cord and no power brick to plug it in. You have to provide your own power brick to charge this. Otherwise its a great product

    Good bank for the price.

    Good capacity. Wish it would automatically start to charge the device, but you need to push the button on the side. Not a big deal, but the others that I have start charging on their own as you plug in the cord to the device that you are trying to charge. Not sure about durability yet. Only used it for a few days.

    Holds a lot of juice!!! I was surprised that I have to switch it on. I expected it to just charge automatically if plugged into a device. But that's okay. I just have to think. It sure has more than enough power to get me through a day!

    Insignia is not worth the $$

    Bought this product and have used only once. Went to use it the other day and it doesn’t work. It is not even a year old and Insignia won’t do anything about it. Not worth a single dollar.

    These are a piece of junk. It worked great at first but here it is a couple years later with only a little use here and there and it no longer works. It is fully charged, but it wont charge anything. It is detected but then immediately stops charging. Get a major brand that will last.
