DC Power Adapter 5.5mm x 2.1mm Female to 4.0mm x 1.7mm Male Conversion Plug Round Injection Moulded Black Connector for Laptop Power Supply and Electronic Devices
DC Power Adapter 5.5mm x 2.1mm Female to 4.0mm x 1.7mm Male Black
This DC power adapter is a straightforward conversion plug designed to bridge a 5.5mm x 2.1mm female jack to a 4.0mm x 1.7mm male plug. It suits situations where a power supply or cable with a 5.5mm x 2.1mm output needs to connect to a device with a 4.0mm x 1.7mm input. The adapter is round and produced using injection moulding. It is black in colour and supplied as a single adapter. No electrical specifications such as voltage or current ratings are provided in the source data, so it should only be used after confirming that the power supply matches the requirements of the device. The compact moulded design allows it to sit between existing connectors without adding significant bulk.
Features and Construction
This section covers the physical build and measurable dimensions of the adapter, based strictly on the available source information.
Material and Build
The adapter is made using an injection moulding process, which typically forms a moulded plastic body around the internal contacts. The round shape helps it align easily with standard barrel jack sockets. The black finish is the only colour option stated. No further material details or durability claims are provided in the source text.
Size and Practical Fit
The female end measures 5.5mm x 2.1mm, while the male end measures 4.0mm x 1.7mm. These are the only dimensions given. This size combination allows a 5.5mm x 2.1mm female connection to mate with a 4.0mm x 1.7mm male input. It is important to check both the outer and inner diameters of your existing jacks to confirm a correct fit.
Uses and Placement
This adapter is intended for DC power connections where the plug sizes differ between a power source and a device.
Event or Professional Use
It can be kept as a spare part in toolkits or equipment bags where multiple devices use different DC barrel jack sizes. Its compact round form takes up little space. The single-pack quantity means it is ready for one specific conversion task.
Everyday Home Use
At home, it may help connect a power supply to a device that has a 4.0mm x 1.7mm power input when only a 5.5mm x 2.1mm output cable is available. No voltage, current, or polarity information is included, so users must verify compatibility independently before plugging it in.
Benefits and Buying Value
The main value of this adapter lies in its ability to solve a specific size mismatch without replacing an entire power supply or cable.
Reuse and Low Maintenance
By converting an existing 5.5mm x 2.1mm female connection to a 4.0mm x 1.7mm male plug, it can help extend the usefulness of a compatible power lead. There are no moving parts mentioned. Cleaning or maintenance instructions are not provided in the source data, so only basic handling care should be assumed.
Why Choose This Product
This adapter is suitable if you specifically need a 5.5mm x 2.1mm female to 4.0mm x 1.7mm male conversion. It is black, round, injection moulded, and supplied as one piece. No additional adapters, cables, or electrical ratings are included. Always confirm the voltage and current requirements of your device before use.
