SKU CH-7ED2-EKGZQ

A 1 metre cable that converts a 5.5×2.5 mm barrel power source into a USB male plug for charging USB devices

  • Product typePower
  • 1 metre cable reaches distant USB devices from a barrel supply
  • 5 mm × 2.5 mm barrel plug fits common DC power adapters
  • USB-A male connector charges phones, tablets and other USB gear
  • 5 mm wire diameter handles typical low-voltage currents
  • Male-to-male design simplifies camera and accessory installations

Power adapter to USB cable

This 1 metre cord connects a 5.5 by 2.5 mm barrel jack to a USB type A plug. It lets you run USB powered gear from a standard DC wall adapter. The cable uses a 0.3 mm² conductor and has a 3.5 mm outer diameter. Condition is new.

Check your barrel jack and USB power needs

Verify that your power adapter has a 5.5 mm outer and 2.5 mm inner diameter barrel connector. Ensure the adapter supplies the voltage and current your USB device requires. The cable itself carries power only and does not negotiate USB charging protocols.

Suits DIY camera and sensor installs.

Builders who need a tidy 3.28 ft link from a barrel jack supply to a USB powered camera or sensor will find this useful. It is not for users who need data transfer, USB C connectors or proprietary fast charge handshakes.

Questions about this item

Does the 1 m cable include both the 5.5×2.5 mm barrel plug and the USB-A plug, or must I buy an adapter separately?

The package contains one 1 m cord with a 5.5×2.5 mm male barrel jack on one end and a USB-A male plug on the other; no extra adapter is required.

How do I know the 5.5×2.5 mm barrel size matches my power supply?

Measure the outer diameter and inner pin of your existing barrel connector; it must be exactly 5.5 mm outer and 2.5 mm inner to fit this cable.

What does the 0.3 mm² conductor cross-section mean for charging a phone or camera?

The 0.3 mm² copper cores are sized for low-power USB charging — typically up to 2 A at 5 V — suitable for phones, cameras and similar 5 V devices.
