SKU CH-CZYJ-MKGQ8

Connects a USB 2.0 port to a 5.5 mm × 2.1 mm DC jack for powering small devices

  • Powers 5 V devices from any USB 2.0 port
  • 5 mm x 2.1 mm barrel jack fits many fans and speakers
  • Female DC socket accepts standard 2.1 mm centre-positive plugs
  • Compact internal cable keeps chassis wiring tidy

USB 2.0 to 5.5 mm DC power adapter

This cable converts a standard USB 2.0 Type-A port into a 5.5 mm by 2.1 mm DC barrel jack. It delivers 5 V power to devices that use this common centre-positive connector. The female socket accepts plugs from small fans, speakers or similar low-voltage peripherals. No driver or configuration is required.

Replaces a dedicated wall wart for USB-powered gear

Use it when a device ships with a mains adapter but a free USB port is available on a PC, power bank or charger. The jump is worth it if the target equipment draws within the USB port's current limit and uses the 5.5 mm by 2.1 mm plug. It will not suit hardware that needs higher voltage or a different barrel size.

Questions about this item

What size DC jack does the 5.5 mm x 2.1 mm female connector fit?

The female jack accepts a standard 5.5 mm outer diameter and 2.1 mm inner diameter barrel plug, matching most USB-powered fans and speakers.

Which way round does the USB 2.0 Male A plug go in, and what happens if it is forced upside-down?

Insert the USB-A plug with the metal contacts facing down; forcing it the other way can bend the internal pins and stop the cable from delivering 5 V power.
