A USB to DC jack cable is very useful as it enables powering DC devices through the standard USB 2,0 ports present in laptops or power adapters. On one end, the cable has a USB 2.0 type connector; on the other, it has a DC jack.
How to use
Plug the USB connector of the wire into your laptop or power adapter. Plug the DC Jack into your device that you want to power through the cable, and you’re done!
