USB 2.0 A Male to 3.5×1.35mm DC Barrel Power Cable, 5V USB to 3.5mm Jack Charging Adapter Cord for Small Electronics

This USB A male to 3.5x1.35mm DC barrel power cord turns any 5V USB power source into a matching power supply for devices with a 3.5mm outer diameter / 1.35mm inner diameter DC jack. You can easily power or charge small gadgets via USB wall adapters, portable power banks, desktop and laptop USB ports without dedicated DC power bricks.

Built with thick conductive copper cores and insulating outer casing, the cable minimizes voltage drop during power delivery to maintain steady device operation. Integrated strain relief on both cable ends relieves tension from frequent plugging and twisting, effectively preventing internal wire fracture.

It is widely applicable for mini surveillance cameras, LED strip lights, Bluetooth speakers, portable routers, digital toys and other low-power 5V electronics with 3.5*1.35mm DC ports. No drivers or complicated setup needed; just plug into a USB power source to supply power instantly, a handy universal replacement charging cord for daily small electrical equipment.
