Unique-Bargains 10pcs DC Power Adapter 5.5mm x 2.1mm Male to 5.5mm x 2.5mm Female Blue

DC adapter pack for CCTV and small electronics

This pack supplies ten barrel adapters that convert a 5.5 mm by 2.1 mm male plug to a 5.5 mm by 2.5 mm female socket. They suit installers extending or repairing low-voltage leads for cameras, sensors or hobby circuits. The blue colour helps identify the converted cable in a loom. Buyers needing a different barrel diameter or polarity should look elsewhere.

Fixed 5.5 mm barrel standard limits

The adapter only bridges the 2.1 mm pin to the 2.5 mm bore; it cannot change voltage, current rating or polarity. Any device requiring a centre-negative tip or a larger outer diameter will not mate. The 42 mm length adds minimal reach, so long runs still need proper extension cable. No locking mechanism means vibration can loosen the joint over time.

Compact moulded bodies with friction-fit barrels

Each unit measures 42 mm by 12.5 mm and weighs very little, so they add negligible bulk behind a camera bracket or inside an enclosure. The smooth barrels rely on friction alone, making insertion easy but offering no positive retention. Ten pieces in one bag give enough spares for multiple sites or future repairs without individual packaging waste.
