What this cable does

This Fervit cable converts a standard USB 2.0 Type-A port into a 5.5 mm by 2.5 mm DC barrel connector supplying 5 V power. It spans 80 cm and is intended for small electronics that draw power through a matching barrel jack. The connector fits devices designed for a 5.5 mm outer diameter and 2.5 mm inner pin.

Suitable uses and limits

It suits hobbyists powering development boards, routers, LED strips or audio gear from a USB charger or power bank. It will not work for equipment that requires a different barrel size, a higher voltage than 5 V, or a USB-C power delivery negotiation. Buyers needing a locking connector or a right-angle plug should look elsewhere.

Critical specification

The barrel dimensions are 5.5 mm outer diameter by 2.5 mm inner diameter. Measure your device's power jack before ordering; a mismatch means the plug will not seat or could damage the socket. Only proceed if your hardware specifies exactly this 5.5 x 2.5 mm 5 V DC input.
