    Everyone should carry a back up battery with them and for this price there is no reason not to. You never know when you might need to charge your phone and you don't have an outlet available.

    The box says "Up to 1 charge", but the most I got was about 25%. If it were almost a whole charge, that would've been great. I ended up returning it on vacation.

    Although the battery is flat, fitting I your pocket, it lacks the power to even charge an iPhone 6+ to half a charge. Not worth the price or effort!
