    A bit chunky and heavier than some similar products, but definitely has the capacity for multiple charges of phones/tablets. Very easy to use, too. A good value and recommended.

    This is a great charger, good for at least 3 charges and not as bulky as some of the other. It also was quick to charge, I recommend.

    Okay so this one is a tough one. The product itself isnt that bad. It works but it is just too slow. Takes forever to recharge and is not very practical in emergency situation. It will work and charge your decives but if you want something fast and practicl , this isnt it.

    This is an okay product. It keeps your devices charged and ready to go… That is once you get one that works(took four tires to get one that works), and when you do, you’ll have to baby it like brand new veneers on your teeth. The board that you plug cables into comes loose on most of them, and doesn’t feel sturdy. That’s because it’s glued in, and not screwed in. Also, this is approved for air travel, but theme parks may not allow it inside.
