DC 5521 Right-Angle Power Adapter

This DC 5521 male-to-female adapter adds a 90 degree elbow to a laptop power connection. It fits barrels with a 5.5 mm outer diameter and a 2.1 mm inner diameter with centre pin. The compact design keeps the plug close to the device chassis. It is intended for notebook users who need a tidy cable route.

Sustained Use and Cable Strain Relief

The right-angle bend reduces leverage on the laptop power jack during long sessions. By directing the cable along the case instead of straight out, it lessens wear on the internal socket. The lightweight body adds minimal mass to the connection point. No active components are present, so heat buildup is not a concern.

Replaces Straight Barrel Plugs

This adapter upgrades a straight DC 5521 plug when desk space or port orientation forces the cable into a sharp bend. It is not for buyers who need a different barrel size or a voltage conversion. The jump is worth it when the existing connector clears the laptop but the cable path does not.

Questions about this item

Does the 90 degree elbow run warm when powering a laptop all day?

The adapter is a passive connector with no active components, so it does not generate measurable heat during continuous use.

What must the power brick already have for this 5.5 mm by 2.1 mm plug to fit?

The brick needs a matching DC 5521 female jack with a centre pin; the adapter simply extends that connection at a right angle.

Will the 5521 connector work with an older barrel jack that has a different inner diameter?

No — the 2.1 mm inner diameter and centre pin are specific; a mismatched jack will not make reliable contact.
