After spending a couple days with this device I can’t let it go. It’s great; you charge it overnight, throw it in your bag and use it whenever you need it throughout the day. It’s especially worth it because you can charge your phone more than once. It’s light, it’s small, and holds one big charge allowing me to never have to use the power outlet again!

Everything about the product is great and the only complaint is that it is a little expensive and it only comes in one color. But really that’s the least of your worries when you have such a great piece of technology. All we can say is.. we’re geeking out about it!

We would like to thank Powermat for giving us the product for review, it was truly a great piece of technology!
