USB-to-barrel cable for 5 V devices

This one-metre white cable converts a standard USB Type-A port into a 5.5 mm outer, 2.1 mm inner DC barrel plug with positive centre pin. It draws 5 V DC from the USB socket to power small electronics such as MP3 or MP4 players. The cable is supplied without retail packaging.

Buyers who need a different barrel size or voltage

The fixed 5.5 mm by 2.1 mm connector and 5 V output mean the cable cannot serve devices that require a larger jack, a smaller inner pin, or a higher supply voltage. Users needing a longer reach or a right-angle plug will also need a different lead.

5.5 mm outer and 2.1 mm inner barrel dimensions

This single connector specification decides whether the cable fits the target device; if the equipment calls for any other barrel diameter or pin polarity, the cable will not work.

Questions about this item

Should I pick this 5.5*2.1mm barrel cable or a different size?

Choose this cable only if your device needs a 5.5mm outer and 2.1mm inner barrel plug with positive centre pin; other sizes will not fit.

What does the 5V from the USB port actually deliver to my device?

The cable passes the 5V DC from the USB port straight to the barrel plug, so your device receives 5V at whatever current the host port can supply.

What does the USB Type-A interface limit in practice?

The USB Type-A male plug limits the output to 5V DC; the current ceiling depends on the host port, not on the cable itself.
