USB-A to 5.5mm Barrel Power Cable

This cable connects a USB Type-A 2.0 port to a 5.5mm barrel jack with a 2.5mm inner diameter. It delivers 5V DC power from a computer or charger to compatible devices. The one metre length uses moulded connectors with strain relief and a shielded PVC jacket for durability.

For 5V devices with Size N barrel inputs

It suits hardware that draws 5V power through a 5.5mm by 2.5mm barrel connector from a USB-A source. Devices requiring a different voltage, a larger inner diameter, or a locking connector will not work with this cable.

Barrel connector Size N with 2.5mm inner diameter

The connector B is a barrel power connector defined as Size N with an outer diameter of 5.5mm and an inner diameter of 2.5mm. Only equipment matching this exact barrel geometry will achieve a secure and reliable power connection.

Questions about this item

Which USB port on my computer can supply power for this cable?

Any standard USB Type-A port that delivers 5 V will work; the cable draws power from the host port and passes it to the barrel connector.

My device uses a 5.5 mm outer diameter barrel jack with a 2.5 mm centre pin — will this cable fit?

Yes, the barrel end is a Size N connector with a 5.5 mm outer diameter and a 2.5 mm inner diameter, matching that specification exactly.

How can I confirm the cable is delivering power after I plug it in?

The connected device should power on or show its charging indicator; if it remains off, try a different USB port or verify the device requires 5 V DC.
