How to add a USB port for charging iPhone or Smartphone on your backpack?

We are talking the gadget showing above.

If your backpack got 1 but unfortunately broken, then just have this one and have it on the same place.

If you don't have one then want to have one, I don't think it is a good way as it is not that easy and we don't suggest therefore we are not going to show here.

FYI...
This is a 0.5meter USB Male to USB Female with Mount for fitting to your backpack or any place that is suitable for the mount.
