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.

Questions about this item
What size power plug does the 5.5mm x 2.1mm male end of this adapter fit?
The male end fits any 5.5mm x 2.1mm female DC jack, the size used on many CCTV cameras and small electronics power inputs.
Will the 5.5mm x 2.5mm female side accept the barrel connector from my existing 12V power supply?
Yes, if your supply has a 5.5mm x 2.5mm male plug — the adapter's female socket matches that exact dimension.
How can I confirm the connection is solid after joining the two cables?
The adapter measures 42mm long; a firm push until the male plug seats fully in the female socket gives a reliable mechanical and electrical connection.
