1m DC Power Extension Cable

This 1 metre DC power extension cable uses a 5.5mm x 2.1mm male-to-female barrel connector to lengthen existing power leads. It suits builders who need to bridge a short gap between a power supply and a device. Buyers requiring a different barrel diameter or a locking connector will not find a match here.

TPE Jacket Handles Routine Bending

The cable sheath combines TPE and PVC over metal contacts to maintain a secure connection during repeated insertion cycles. It is designed for standard indoor routing where the lead lies flat or follows gentle curves. Installations subject to tight bends, continuous flexing or outdoor exposure fall outside its intended use.

Fixed 5.5 x 2.1mm Interface Limits Compatibility

The barrel connector adheres to the common 5.5mm outer and 2.1mm inner diameter, so it only mates with matching jacks. Polarity follows the usual centre-positive convention but is not mechanically keyed, so verifying the device requirement remains essential. Adapters for other barrel sizes or screw-terminal blocks are not included.

Questions about this item

Does the 1 m cable add noticeable resistance when my 5.5 x 2.1 mm adapter runs continuously?

The 1 m length uses TPE+PVC conductors rated for 8 A, so voltage drop under continuous load stays minimal for typical DC devices.

What must I already have so the female jack accepts my power brick?

Your existing supply needs a 5.5 mm outer diameter and 2.1 mm centre pin male plug to mate with the female connector.

Will the male end fit the 5.5 x 2.1 mm input on my older router?

Yes, the male plug matches the 5.5 mm by 2.1 mm barrel size used on many legacy routers and similar gear.
