How to use

Connect the AC adapter to an AC mains outlet, then plug the USB-C connector into the device's USB-C charging port. The adapter and the connected device negotiate voltage and current automatically via USB Power Delivery; once negotiation completes, charging begins. Ensure the device is placed on a stable surface and cables are routed to avoid strain on connectors. Disconnect from the mains and device when charging is complete or when the adapter is not in use.

Recommendations

Use this adapter with devices that explicitly support USB-C Power Delivery and with compatible Lenovo systems. For optimal performance, use the original or certified USB-C cable and avoid exposing the adapter to moisture, extreme temperatures, or prolonged direct sunlight. If the device draws less than 100W, the adapter will supply the appropriate lower power level automatically.
