100W USB-C Power Adapter

This adapter converts a USB-C power source into a 5.5 x 2.5 mm barrel jack for laptops and devices needing that connection. It supports up to 100 W power delivery across 18.5 to 20 V input. The short 8 cm cable with an elbow connector keeps the setup tidy on a desk or in a bag. It is aimed at users replacing a lost proprietary charger with a universal USB-C supply.

Check Your Device Port and Voltage

Verify that your device uses a 5.5 mm outer diameter and 2.5 mm inner diameter barrel port before ordering. Confirm the laptop or equipment requires 18.5 to 20 V input, as the adapter passes the source voltage directly. Ensure your USB-C charger or power bank can deliver the required wattage up to 100 W. The fixed 8 cm cable length offers no slack, so the power source must sit close to the device.

Replaces Bulky Proprietary Bricks

This adapter replaces a manufacturer-specific AC brick when you already own a capable USB-C PD charger. The jump is worth it if you want one charger for a laptop, phone and tablet while travelling. It does not add voltage regulation, so the USB-C source must match the device voltage exactly. Buyers needing a longer reach or a different barrel size will need a different solution.

Questions about this item

What comes in the box and what extra cable or charger do I need to supply?

The box contains an 8 cm elbow adapter cable with a USB-C female port on one end and a 5.5 × 2.5 mm male barrel plug on the other. You must provide a USB-C power source capable of 100 W at 18.5–20 V.

How do I know whether the 18.5–20 V 100 W rating matches my laptop’s barrel jack requirement?

Check your laptop’s original charger label for a 5.5 mm outer diameter, 2.5 mm inner diameter barrel connector and a voltage between 18.5 V and 20 V. If both figures match, this adapter will deliver up to 100 W.

When I plug this into a 100 W USB-C charger, will my laptop actually receive 100 W through the 5.5 × 2.5 mm tip?

The adapter passes up to 100 W at 18.5–20 V from the USB-C source to the barrel plug. Actual power drawn depends on your laptop’s charging circuit and the USB-C charger’s PDO profile.
