Two short black USB-A to 5.5 x 2.1 mm barrel cables

Yeworth DM-09 USB 2.0 to DC 5.5 x 2.1mm 5V Power Cable 0.25m 2 Pack

SKU CH-F1XH-7Z9CJ

Two short cables let you run 5 V barrel-jack devices from any USB 2.0 port

  • Overall length0.25 m
  • Powers 5V devices from any USB 2.0 port
  • Compact 0.25m length reduces cable clutter
  • 5 x 2.1mm barrel plug fits compatible DC inputs
  • Two cables included for spare or multi-device use
  • Supports up to 2A current for reliable charging

Power on the go

This two-pack of short USB 2.0 to 5.5 x 2.1 mm barrel cables lets you run 5 V DC gear from any laptop, desktop or power bank. Each lead is 0.25 m long and rated for loads up to 2 A, so you can leave bulky wall adapters behind when travelling. The positive-centre plug fits devices that accept the 5.5 mm outer and 2.1 mm inner diameter.

Two cables in one pack

Having a spare means you can keep one connected to a stationary device and carry the other in a laptop bag. The black plastic and copper construction is simple and lightweight, with a Type-A male plug on one end and the coaxial barrel on the other. No extra software or drivers are required; the connection is purely passive power delivery.

Check the barrel size first

Measure the inner and outer diameter of your device's DC jack before ordering; this cable only fits the 5.5 mm by 2.1 mm standard. Confirm the equipment operates at 5 V and draws 2 A or less, otherwise the cable will not supply enough current. It will not work with other barrel sizes or higher-voltage gear.

Questions about this item

Will the barrel connector wear out from repeated plugging and unplugging?

The cable uses a standard 5.5 mm outer and 2.1 mm inner barrel plug; normal insertion cycles are rated for thousands of mates, so replacement is unlikely unless the connector is physically damaged.

What is the maximum current the cable can sustain without voltage drop?

The supplier specifies a maximum load of 2 A; sustained draws above that will cause voltage sag and may trigger the host USB port's over-current protection.

Does the cable or its connectors get warm when powering a 2 A device all day?

At the rated 2 A limit the copper conductors and USB Type A plug may become slightly warm, but the short 0.25 m length keeps resistive heating minimal.
