USB-to-DC 5.5 mm × 2.1 mm power cable 2-pack

This 2-pack supplies two USB-A male to DC 5.5 mm × 2.1 mm male cables, each 1 m long and built with 22 AWG pure copper conductors inside a flexible PVC jacket. The connectors are male-to-male and rated for 5 V at up to 3 A, making them suitable for powering low-power 5 V devices from any standard USB-A port.

Users who need 5 V DC power for lights, fans.

The cables suit anyone powering 5 V equipment that uses a 5.5 mm × 2.1 mm barrel jack and draws no more than 3 A. They are not for devices that require a higher voltage, a different barrel size, a locking connector, or data transfer through the USB end.

5 V 3 A maximum output on a 5.5 mm × 2.1 mm barrel

The single deciding specification is the 5 V 3 A limit on the 5.5 mm outer-diameter, 2.1 mm inner-diameter DC plug; any device needing more current, a different voltage or a different connector will not work with these cables.

Questions about this item

How do I connect the USB A male plug and the DC 5.5mm x 2.1mm male plug, and what polarity mistake should I avoid?

Plug the USB A male end into any 5V USB port and the DC 5521 male end into the device's power jack, ensuring the 2.1mm centre pin matches the device's positive polarity requirement.

Which part of the cable is most likely to need replacement after repeated bending near the connectors?

The PVC jacket and 22AWG copper conductors at the strain relief points can fatigue over time, so inspect for exposed wire or intermittent charging and replace the cable if damage appears.

What limits the cable's performance during continuous 3A charging sessions?

The 22AWG copper wire and USB 2.0 A male connector are rated for 5V at 3A max; sustained loads at that level may cause voltage drop or connector heating, so monitor device stability.
