A lot of people on the road have asked me what this device is when I pull it out at a club, airport, plane or walking down the street. This is basically my life saver when your phones are dead and there is no outlet around, or you just don’t have the time to stand up against a wall. The Zagg sparq 2.0 charges 2 usb devices 4x over at the same time with an internal battery that you charge plugged into a wall socket. It’s cheap and it does the job over and over and over again! Im feeling like the “Geek Squad” now…BYE!
