  • Product typePower

3-piece barrel-to-USB power cords

This set includes three 1-metre cables that convert a 3.5 x 1.35 mm barrel jack into a USB-A plug. Each cord lets you run USB-powered gear from an existing barrel-output adapter. The wire has a maximum outside diameter of 3.5 mm.

Plug-in installation with size check

Connection is a simple male-to-male fit: insert the barrel end into the power supply and the USB end into the device. The only common issue is a mismatched barrel diameter, so verify the 3.5 mm outer and 1.35 mm inner dimensions before ordering.

Suits USB devices on barrel adapters

Ideal for powering routers, cameras or LED strips that take USB input from a barrel-output brick. Not suited for devices needing a different barrel size, higher current than the adapter provides, or a USB-C power connection.

Questions about this item

How can I verify the 3.5x1.35mm barrel-to-USB cable is delivering power correctly after connecting it?
