Backpack straps ports are designed to add a power port to your backpack strap to charge your phone on the go without having to handle the power bank either on hand or running the cable from the backpack. In addition, the power port also includes a 3.5mm Jack for audio, if you ever put your phone in your back but still listen to music. There are four parts: Only USB, only 3.5mm Jack, 3.5mm Jack & USB and Dual USB. We recommend using eyelets and/or burning around any holes you make on your backpack to ensure the fabric doesn't start to "break down" and to maintain the strength of the backpack.
