DC Power Adapter 5.5 x 2.5mm Male-to-Male

This 50 cm DC power adapter connects two devices using 5.5 mm outer and 2.5 mm inner barrel plugs. It suits builders who need a short, tidy link between a power supply and equipment that both present a female jack. The moulded TPE and PVC jacket keeps the cable flexible for routing inside enclosures. It is not for users who require a longer reach or a different barrel diameter.

Capacity and Headroom 8A Maximum Current

The cable is rated for a maximum current of 8 A, giving headroom for typical low-voltage DC loads such as LED strips, CCTV cameras or small routers. Voltage drop stays negligible over the 50 cm length at normal operating currents. It runs out of margin if the connected load exceeds the 8 A rating or if the supply voltage is pushed beyond the connector specification. Builders needing higher current must choose a heavier gauge lead.

Bundled Simplicity and Installation Speed

The package supplies only the single male-to-male cable with no extra ferrules, heat-shrink or mounting clips. Its pre-terminated ends eliminate soldering or crimping, so installation is reduced to plugging both sides into the matching female jacks. The simple construction means there is no software, driver or firmware to configure. Users who want strain-relief boots or colour-coded markers must add those separately.

Questions about this item

Will the 5.5 mm by 2.5 mm plugs on this adapter fit the barrel jacks on my existing router and switch?

The connector is a 5.5 mm outer diameter by 2.5 mm inner diameter male plug, so it matches devices that use that exact barrel size.

How can I confirm the cable is delivering power correctly after I connect it?

The adapter supports up to 8 A; if the connected device powers on and runs without voltage drop, the link is working as intended.

Does the package include both the 50 cm cable and the longer 1 m or 1.5 m versions, or must I buy those separately?

Each unit is a single 50 cm cable; the 1 m and 1.5 m lengths are sold as separate items.
