A:Answer Hey Arran,
You can charge the Yoga Pro 9i Aura Edition via its two USB-C (Thunderbolt 4) ports that support charging up to 100W. Although, we wish to note that this unit was not designed with USB-C charging solely in mind, and by not delivering a high enough wattage to the laptop, your system may charge slower, and even during strenuous workloads the battery may drain faster than the 100W or lower USB-C charger can supply and performance may drop during that time.
