USB to 5.5x2.1mm barrel power cable

This cable delivers 5 V DC power from any standard USB Type-A port to devices fitted with a 5.5 mm outer and 2.1 mm inner coaxial barrel jack. The centre-positive polarity matches the majority of small routers, hubs, LED strips and development boards that ship without a dedicated mains adapter. It is intended for users who want to reduce wall-wart clutter by powering compatible gear from a USB charger, power bank or PC port.

Fits USB-A sources and 10 mm barrel sockets

The USB-A male plug connects directly to chargers, laptops, desktop ports or portable batteries without an intermediate adapter. At the far end, the 10 mm barrel length seats securely in jacks that require the longer sleeve, avoiding the intermittent contact common with shorter plugs. The 1.5 ft / 50 cm span keeps desk runs tidy while still reaching nearby equipment. No driver installation or configuration is required; the cable simply passes the host’s 5 V supply through to the load.

22 AWG copper handles 3 A with minimal loss

The 22 AWG copper conductors are rated for up to 3 A continuous current, keeping voltage drop low across the short length so attached devices receive stable power. In normal use the cable runs cool and adds no audible noise because it contains no active electronics or moving parts. Power draw is determined entirely by the connected load and the host port’s current limit, making it a passive, reliable link for any centre-positive 5 V device within the 3 A rating.
