  • Supplies power to small electronics with 5.5 mm jack

Power cable for 5.5 mm barrel devices

This USB 2.0 Type-A to 5.5x2.5 mm DC cable delivers 5 V power to small electronics that use a standard barrel jack. The 1.0 M length suits desk or bench setups where the host USB port is nearby. It is intended for hobbyists, repair technicians and anyone powering legacy hardware from a modern USB source. Devices needing higher voltage or a different barrel size cannot use this cable.

Thermals noise and power draw

The cable carries only the 5 V supply provided by the host USB 2.0 port, so heat and noise are limited to the connector ends. No active cooling or fan is present, making operation silent. Power draw matches the attached device up to the host port’s current limit, with no additional conversion losses beyond the conductors themselves.

Behaviour under sustained load

Voltage remains at 5 V as long as the host port maintains its rated output during continuous use. The fixed 1.0 M conductor length keeps resistance stable, so voltage drop does not increase over time. Performance is therefore consistent for extended sessions, provided the source port can supply the required current without throttling.

Questions about this item

How do I connect the 5.5 x 2.5 mm barrel plug to my device without damaging the centre pin?

Align the 5.5 mm outer sleeve first, then push straight in until the 2.5 mm centre pin seats fully; forcing it at an angle bends the pin and breaks the connection.

Will the USB 2.0 Type-A end wear out from repeated plugging and unplugging?

The USB 2.0 connector is rated for typical daily insertion cycles; if the spring tabs lose tension or the port feels loose, replace the cable to maintain reliable 5 V delivery.

What limits the cable when powering a device continuously at 5 V?

The 1.0 m length and USB 2.0 conductor gauge set the practical current ceiling; sustained loads near the port's maximum will cause voltage drop and heat in the wire.
