Ten-piece adapter set

This pack contains ten DC power adapters that convert a 5.5mm x 2.5mm male plug to a 5.5mm x 2.1mm female jack. They are intended for hobbyists, installers and technicians who need to match different barrel connector sizes on low-voltage devices. The yellow colour helps identify the adapters in a parts bin or behind equipment racks. Each unit measures 41mm long by 12.5mm in diameter.

5.5 mm by 2.5 mm to 2.1 mm conversion

The critical specification is the connector transition: a 5.5mm outer diameter male tip with a 2.5mm centre pin stepping down to a 5.5mm outer diameter female sleeve accepting a 2.1mm centre pin. Only devices using exactly those two barrel sizes will mate correctly. No voltage regulation or polarity change is provided by the adapter itself.

Ready-to-use bulk quantity

The package delivers ten identical adapters with no additional cables, screws, tools or software. This quantity suits installers running multiple CCTV cameras or builders assembling several small electronics projects at once. Buyers who need a different barrel size, a solder-on pigtail or a single unit must look elsewhere.
