4-piece DC connector adapter set

This pack contains four black adapters that convert a 7.4mm by 5.0mm male barrel plug into a 5.5mm by 2.1mm female socket. They are intended for hobbyists and installers who need to match mismatched power leads on small electronics or CCTV equipment.

Compact passive design draws no extra power

Each unit measures 52mm by 17mm by 13.5mm and adds no active circuitry, so thermals, noise and power draw remain unchanged from the source supply. The moulded black housing simply passes the existing voltage and current through the new connector geometry.

Four adapters enable multiple device connections

The bundle provides four identical tips, letting you prepare several cables to a desired length or replace broken connectors across several cameras or project boards at once. No software or additional accessories are included.

Questions about this item

How do I install the 7.4mm x 5.0mm male to 5.5mm x 2.1mm female adapter, and what step do people get wrong?

Push the male end fully into the power source until the 52mm body seats, then insert the device plug into the 5.5mm x 2.1mm female side; the common error is leaving a gap that breaks contact.

What maintenance or replacement will these DC connectors need later?

Inspect the 5.5mm x 2.1mm female bore and 7.4mm x 5.0mm male pins for oxidation or looseness; replace any adapter that shows intermittent power or physical damage to the 13.5mm housing depth.

What limit appears first when these adapters run under sustained load?

The 5.5mm x 2.1mm contact interface will heat and loosen before the 7.4mm x 5.0mm male side, causing voltage drop or disconnection during continuous draw.
