Nice quality portable charger, it is designed to charger super fast every device you connect to it, one of my travel companions everywhere I go because I can charger my camera, ipad, iphone, portable battery all at once using only one plug and with it’s dual voltage (110-240v) there’s no worry about connecting it anywhere in the world. This is specially helpful in Europe where I've been in places where there is only 2 wall outlets in the room, so prioritizing devices to charge it's no longer necessary as I can charge everything at the same thing. The device itself it's intelligent because each USB has a chip that tells it status about power or temperature that helps bring it's performance to the top level.
