    Compact and Gets the Job Done

    I purchased this for the size and understood that it wouldn't completely charge my iPhone 6 but it provides enough charge, about 30-40%, where I was looking for a charge to at least make a phone call or text and check email. The size is small and flat enough to carry in your pocket.

    Not Enough Juice

    I was expecting that this would give my phone at least one full charge (I have an iPhone 5) but it only gets me about 1/2. I travel quite a bit and I need something with more juice!
