Power Adapter for USB-C Laptops
This eForChina adapter converts a USB-C power source to a 5.5 x 1.7 mm barrel plug. It handles up to 100 W at 18.5 to 20 V for compatible devices. The 8 cm nylon-braided cable ends in a right-angle connector to reduce strain on the port. Plug-and-play operation requires no drivers or configuration.
Suitable for Slim Laptop Charging
Users with laptops that charge via a 5.5 x 1.7 mm jack and support USB-C PD input can use this cable with a suitable power bank or charger. It is not for devices that require a different barrel size or a higher voltage than 20 V. Buyers who need a straight connector or a longer cable should look at something else.
5.5 x 1.7 mm Output Connector
The critical specification is the 5.5 mm outer diameter and 1.7 mm inner pin of the male barrel plug. This must match the laptop's charging port exactly for a secure connection and correct power delivery. Verify the port dimensions on the target device before ordering.

Questions about this item
Will this adapter power my older laptop that uses a 4.8 x 1.7 mm barrel jack?
The adapter provides a 5.5 x 1.7 mm male output plug, which is larger than the 4.8 x 1.7 mm jack on your laptop, so it will not fit without a separate sleeve converter.
How can I confirm the adapter is delivering the full 100 W to my device?
The adapter supports USB Power Delivery up to 100 W; verify actual charging rate using your laptop's battery settings or a USB-C power meter while connected to a compliant PD charger.
Does the package include a USB-C power brick or only the short adapter cable?
Only the 8 cm nylon-braided adapter cable with a USB-C female input and 5.5 x 1.7 mm male output is included; a USB-C PD charger must be purchased separately.
