Proswell built excellent build qualitylooks great better than a charger that comes with most phones2 usb ports per unit to charge multiple devices if needed my wife and i sometimes charge both our phones in the living roompowerful enough to charge an ipad at full speedive had them for over a month now and would definitely buy another pack if needed however i think this product will last me a long time

I have also added one to my regular work bag in case i need to charge while i am out
