Unique-Bargains DC Power Adapter 5.5mm x 2.1mm Male to 5.5mm x 2.5mm Female Blue 4pcs

Four-piece DC connector set

This pack contains four DC power adapters that convert a 5.5 mm x 2.1 mm male plug to a 5.5 mm x 2.5 mm female socket. Each unit measures 42 mm in length and 12.5 mm in diameter. The blue finish provides quick visual identification in a parts bin. They are intended for extending or repairing low-voltage power leads.

Suited for CCTV and hobby projects

Installers who need to match a 2.1 mm centre-pin supply to a 2.5 mm device jack will find these adapters convenient. They also help hobbyists build custom-length cables for small electronics. Buyers who require a different barrel size, a right-angle form factor, or a locking connector should look elsewhere.

Fits inline on existing cable runs

Each adapter sits between the power source and the device, adding roughly 42 mm to the overall length. No tools or soldering are needed; the connection is made by pushing the male end into the supply and the device plug into the female end. This frees the builder from cutting and re-terminating cables when only the tip size must change.
