USB to 5.5 x 2.1mm barrel power cable

This cable delivers 5V DC power from a standard USB Type-A port to devices fitted with a 5.5 x 2.1mm barrel jack. It is intended for routers, switches and similar network equipment that use this common connector size. The 120cm length gives flexible placement around a desk or rack. The cable is rated for a maximum current of 1A.

Suitable for powering compatible network gear

Users who need to run a router or switch from a power bank, PC or USB charger will find this cable matches the required jack and voltage. It is not for devices that need a different barrel diameter, a higher voltage than 5V, or more than 1A of current. Buyers whose equipment uses a locking connector or a centre-positive polarity other than the standard should verify compatibility before purchasing.

1A maximum current rating

The cable supports up to 1A at 5V, so the connected device must draw no more than this amount. Exceeding the rating can cause voltage drop, overheating or damage to the cable and the USB host. Check the device's power specification to confirm its current draw is within the 1A limit before use.

Questions about this item

How much current can the 5.5 x 2.1mm barrel connector deliver continuously?

The cable is rated for a maximum of 1A at 5V DC, so it can power devices drawing up to that limit from a standard USB port.

Which USB port type is required on the host side?

Connector A is a standard USB Type-A male plug, so any USB-A port supplying 5V will work.

Will the 120cm length reach a router mounted on a high shelf from a floor-level power bank?

At 120cm (4 feet) the cable spans most desk-to-shelf distances, but measure your exact routing path before relying on it.
