7.4mm to 5.5mm DC Adapter Pair

This pack supplies two new DC power adapters that convert a 7.4mm by 5.0mm male plug into a 5.5mm by 2.1mm female socket. They suit hobbyists, installers or repairers who need to connect mismatched barrel connectors on small electronics or CCTV equipment. Each unit measures 47mm by 13mm by 13mm and comes in black.

Inline Connector for Cable Modification

The adapter sits inline between an existing 7.4mm power lead and a 5.5mm device input, letting you extend or repair a cable without soldering. It frees you from hunting for a matching power supply when only a different barrel size is on hand. The compact body fits tight enclosures and camera housings where bulkier couplers would not.

Two Identical Units for Spare or Dual Use

The package includes two identical adapters so you can equip two devices or keep one as a spare. No driver, firmware or extra accessory is supplied because none is required for this passive connector. Having the pair on hand speeds up bench testing and field replacements alike.

Questions about this item

Does the 13 mm wide housing leave enough clearance when the adapter is plugged into a tightly spaced CCTV power block?

The adapter measures 13 mm wide by 13 mm high, so it fits beside most standard barrel-jack sockets without blocking adjacent ports.

Will the adapter body become noticeably warm when left connected to a camera supply all day?

It is a passive metal-to-metal barrel converter with no active components, so it does not generate measurable heat during continuous use.

Which cable or power supply must the buyer already have to use the 7.4 mm male plug on this adapter?

You need a source cable or PSU fitted with a 7.4 mm x 5.0 mm female DC jack; the adapter then provides a 5.5 mm x 2.1 mm female socket for your device.
