Game changer
Game changer. Takes portability to a new level. You can power the Pro Stringer without the limitation of having to plug it into the wall. You can also SUPER FAST CHARGE your mobile devices about 6 times as well. It has 2 USB-C, 1 USB-A and 1 DC output ports. The supplied connector cable for Pro Stringer is very robust and better than original power cable.
