Connector Size and Gender Change
This pack contains ten elbow adapters that convert a 4.5 x 3.0 mm female DC jack into a 5.5 x 2.1 mm male plug. They suit users who need to connect a larger-barrel power supply to a notebook or device with the smaller socket.
Practical Limits of the Barrel Interface
The adapter passes only the voltage and current the original supply provides; it does not regulate or convert power levels. Polarity follows the source connector, so the centre pin remains positive or negative exactly as the supply dictates. Physical strain on the elbow joint can loosen the connection if the cable pulls sideways.
Installation Ease and Common Issues
Each unit pushes on without tools and the compact 30 x 32 mm body fits tight spaces. The PC and metal construction holds shape but the small pins can bend if forced into a misaligned jack. Buyers who need a straight-through coupling or a different barrel diameter cannot use this specific gender changer.

Questions about this item
What does the 10-piece pack of 4.5 x 3.0mm to 5.5 x 2.1mm adapters cover?
The pack contains ten identical elbow connectors, each converting a 4.5 x 3.0 mm female barrel jack to a 5.5 x 2.1 mm male plug for notebook power supplies.
Will the 5.5 x 2.1 mm male end fit my laptop's charging port?
The 5.5 mm outer diameter and 2.1 mm centre pin match the common barrel size used on many notebook chargers; verify your original tip measures the same before use.
Does the elbow shape change the electrical rating of the DC connection?
No, the right-angle housing only redirects the cable; the adapter passes the same DC voltage and current as the original charger and cable allow.
