PD 20V USB Male Adapter

This adapter connects a USB-C power delivery source to compatible ThinkPad, ThinkBook or Xiaoxin laptops. It is designed for users who need a compact replacement or spare connector for 20 V charging scenarios. The unit supports automatic voltage selection for safe operation. Plug-and-play operation requires no driver installation.

Compatibility and power checks

Verify that your laptop accepts 20 V input via its USB-C or proprietary charging port before ordering. Confirm the charger or power bank you intend to use can negotiate 20 V output under the USB Power Delivery specification. Ensure the physical connector shape matches the port on your specific model. No driver or software configuration is required.

Build and daily use

The black housing measures 4.6 cm by 1.4 cm and weighs very little, making it easy to carry in a laptop bag. Durable materials protect the internal contacts during frequent insertion and removal. The fixed male plug means no separate cable is needed, reducing clutter at the desk or on the move. Simple plug-and-play action suits travel and hot-desking workflows.
