DC Power Connector Kit

This Boxwave kit supplies sixty pieces of 5.5 mm by 2.1 mm DC power connectors. The pack contains twenty male plugs, twenty female panel-mount sockets and twenty dustproof plugs. All parts use high-temperature nylon bodies with silver-plated contacts for reliable low-voltage connections.

Suits hobbyists repairing chargers

Makers who need a bulk assortment of matching plugs and sockets for media players, audio gear or notebook power leads will find the quantities convenient. Installers who require screw-terminal blocks, right-angle bodies or locking shells should source a different connector range.

5.5 mm x 2.1 mm barrel size

Every male plug, female socket and dust cap in the kit shares the 5.5 mm outer and 2.1 mm inner diameter. This single dimension determines whether the connectors mate with the target device, so verify the equipment jack before ordering.

Questions about this item

What does the 5.5 mm × 2.1 mm size limit in practice?

The 5.5 mm outer and 2.1 mm inner diameters match standard barrel jacks, so the connectors only fit devices that use that exact coaxial power interface.

What panel cut-out and clearance do the female sockets need?

Each female screw-panel socket requires a round cut-out that accepts the 5.5 mm barrel and enough depth behind the panel for the 3-pin terminal block and nut.

How are the male plugs and female sockets terminated, and what step is often missed?

Both male plugs and female sockets use solder terminals; the common mistake is forgetting to slide the strain-relief boot or dust cap onto the cable before soldering.
