DC Power Conversion Plug Adapter 5.5x2.1 Female to 4.0x1.7 Male Connector for Power Supply and Charger Cables Black Round Injection Moulded Plug
DC Power Conversion Plug Adapter – 5.5x2.1 Female to 4.0x1.7 Male
This DC power conversion plug adapter provides a practical solution for connecting devices with different barrel jack sizes. It converts a standard 5.5x2.1mm female DC socket to a 4.0x1.7mm male plug, enabling compatibility between power supplies, chargers, and electronic equipment. The adapter is made from injection-moulded plastic and has a round shape, ensuring straightforward use without special tools or soldering. It is supplied as a single black unit.
Features and Construction
The adapter is designed specifically for DC power connections. Its construction and materials are chosen for reliable electrical isolation and mechanical fit.
Material and Build
The adapter is made from injection-moulded plastic, which provides electrical insulation and a durable housing for the connector pins. The round shape fits standard DC barrel jacks, and the black colour gives a neutral appearance suitable for most setups.
Size and Practical Fit
The female end accepts a 5.5mm outer diameter plug with a 2.1mm centre pin. The male end measures 4.0mm outer diameter with a 1.7mm centre pin. These dimensions are common in many low-voltage power supplies and chargers, making the adapter useful for converting cables or device inputs.
Uses and Placement
This adapter is designed for use in electronics, hobbyist projects, and equipment repairs where plug size conversion is needed.
Event or Professional Use
Technicians and engineers can use this adapter to quickly test or power devices that require a 4.0x1.7mm plug from a supply fitted with a 5.5x2.1mm output. It fits neatly into cable management systems and reduces the need for multiple custom cables.
Everyday Home Use
Home users can employ this adapter to power routers, security cameras, LED strips, or other electronics where the original power supply plug does not match the device input. It offers a simple, reversible conversion.
Benefits and Buying Value
The main advantage of this adapter is its simplicity and direct functionality.
Reuse and Low Maintenance
The adapter requires no maintenance; it is a passive component that can be reused across multiple devices. Its plastic construction resists corrosion and wear under normal indoor use.
Why Choose This Product
This adapter serves a specific conversion need: it is the correct choice when you have a 5.5x2.1mm female source and need to connect to a 4.0x1.7mm male input. No other features are claimed beyond this function.
