PD 20V Big Square USB Male Adapter

This power adapter connector fits ThinkPad, ThinkBook and Xiaoxin laptops using the big square USB male interface. It is designed for owners who need a replacement or spare connector for these specific devices. The silver-grey unit is new and ready for immediate use. It does not serve laptops that require a different barrel or USB-C power input.

Automatic voltage selection and physical limits

The adapter automatically selects the correct voltage up to 20V for safe and efficient charging. Its fixed big square USB male plug cannot connect to standard USB-A, USB-C or proprietary barrel ports. The 4.6 cm by 1.4 cm body size determines the clearance needed at the laptop port. No cable is included, so the reach is limited to the adapter length itself.

Compact capacity for travel charging

The lightweight 4.6 cm by 1.4 cm form factor fits easily in a laptop bag for mobile charging. It comfortably handles the 20V PD requirement of compatible ThinkPad, ThinkBook and Xiaoxin models. It runs out when the laptop demands a different connector shape, a higher voltage than 20V, or a tethered cable for flexible positioning.
