    I was recently traveling abroad and this portable charger was extremely handy. The portable charger lasted quite a while before needing to be recharged.

    Used this one time so far and gave good service for the hour I used it, recharged it and has held charge since stored in bag. Happy and handy.

    This kept mine and my wife's iPhones charged while spending a week in NYC, while walking around the city when we had no realistic way to charge them.

    I bought this as a Christmas gift for my son. He loves it. He said his friends are jealous and it works very well. I'm going to buy one for me.

    Great battery for the price. Decided against buying a battery case because every time you buy a new phone it becomes obsolete.

    The portable power bank is a wonderful accessory. It comes in handy when you are away from home and charges your electronic devices very quickly.

    This is a lifesaver when I can't find a place to charge my phone or laptop. It holds several charges for either device. So glad I bought it!

    I needed a backup power supply for my IPad as I travel to Europe every so often and this filled the ticket. As a bonus the price was right.

    My son uses this when he has to be at school all day. It helps to have something portable not having to rely on an outlet.

    Comes in a very sleek design. Great charging power for all portables including tablets. No power button with auto on/off feature. A little bit pricey but overall, it's a great buy.

    Good Immediate Back Up Power

    This product does its job in that it will provide additional power/energy to your iPhone and Android phones when you're on the go. The portability is what makes it nice too. You can power two phones at a time but it will decrease speed as far as charging time (in other words, longer to charge two phones to bring them up to full power). Good to put in backpacks, purses or even deep pockets (like jackets).

    I bought this item mainly to be able to charge my kids tablets when we are on the road or out and about. This can charge two at once which is pretty cool. I also use it for my phone. My only complaint is it can be quirky when you first plug it in. You have to shake it to activate and sometimes the device does not recognize that I am trying to charge it. Other than that great product and great charging life.
