What the cable does

This 1-metre cable converts a 5.5x2.5mm barrel power output into a standard USB-A male plug. It lets you run USB-powered devices such as cameras or LED strips from an existing DC adapter. The pack contains two identical white cables.

Build integration

The male-to-male design plugs directly into a barrel jack on one side and a USB port on the other, removing the need for a separate USB power brick. At 3.28 ft the cable reaches most desk or wall-mounted positions without excess slack. The 3.5 mm outer diameter keeps routing tidy in tight cable channels.

Sustained operation

The conductors are sized for continuous low-voltage DC delivery to USB loads. No active electronics are inside the cable, so heat rise depends only on the connected power supply and the device drawing current. The barrel connector must match the source exactly to maintain a secure connection over long periods.

Questions about this item

How long can the 1M cable run before voltage drop affects a 5V USB device?

At 1 metre the 3.5mm wire keeps resistance low, so typical 5V loads stay within spec.

Does the cable or its connectors get warm during all-day use?

The 3.5mm diameter conductors and simple barrel-to-USB path produce negligible heat under normal USB current.

Which barrel-jack power supply do I need to make this cable work?

Any DC adapter with a 5.5mm outer and 2.5mm inner barrel plug that delivers 5V USB-compatible power.
