TV Recorder Power Cord DC4 Pin Conversion Line 5 for Round 5.5*2.5mm to Four-Pin Notebook Adapter

This conversion cable lets you connect an existing laptop power adapter with a round 5.5*2.5mm output to a newer notebook that uses a four-pin DC input. If you have upgraded your laptop but your old adapter still works, this cable saves you from purchasing a complete new power supply. The output power parameters remain unchanged, so your adapter operates as before. It is a simple, practical accessory for users who want to reduce e-waste and keep using functional equipment. The cable comes in black and includes one piece per pack. Before buying, verify your adapter's interface size and your notebook's connector type to ensure compatibility.

Features and Construction

This conversion line is built for straightforward connectivity between two common DC power interfaces. Its design focuses on maintaining electrical performance while adapting connector shapes.

Material and Build

The cable uses standard electrical wiring materials typical of power cords. It is constructed with a round 5.5*2.5mm plug on one end and a four-pin DC connector on the other. The black outer jacket provides basic insulation and protection for everyday use.

Size and Practical Fit

The exact cable length is not specified, so you should measure the distance between your adapter and laptop to confirm it will reach. The round plug fits adapters with a 5.5mm outer diameter and 2.5mm inner pin. The four-pin connector matches notebooks that use that interface type. No other sizes are supported.

Uses and Placement

This cable is intended for users who already own a round-tip adapter and want to connect it to a four-pin laptop. It works in home, office, or travel settings where the adapter is placed near the computer.

Event or Professional Use

For professionals with multiple laptops, this cable can adapt an older charger to work with a newer company-issued notebook. It is useful in offices where power adapters are shared between different models with compatible power specs.

Everyday Home Use

At home, you can keep your old adapter in service when upgrading to a newer laptop. This reduces clutter and waste. Place the adapter on a desk or table near the computer, ensuring the cable is not stretched tight.

Benefits and Buying Value

The main advantage of this conversion cable is cost saving and convenience. Instead of buying a new adapter, you reuse what you already own.

Reuse and Low Maintenance

Because the cable simply passes through the same electrical parameters, there are no moving parts or settings to adjust. It requires no maintenance beyond occasional inspection for damage. Keep it clean and store it loosely coiled when not in use.

Why Choose This Product

If your adapter has a round 5.5*2.5mm plug and your notebook uses a four-pin input, this cable is a direct solution. It avoids the expense and waste of a full adapter replacement. The cable is straightforward and does what it promises with no extra features needed.
