⚠️ Important Usage Notes

1. This adapter converts your Lenovo laptop charger's DC square-pin output to a USB-C PD output. Use only a compatible Lenovo laptop charger as the power source — do not connect to a wall outlet directly.
2. The input power must be equal to or greater than the desired output power. For example: if your Lenovo charger is rated at 65W (20V/3.25A), the maximum USB-C PD output will be 65W, not 100W. To achieve 100W output, your charger must be rated at 100W or higher (e.g. 20V/6.75A = 135W).
