While Legions support USB-C PD charging, they only support up to 100W (20V 5A).
Due to its low wattage, the laptop can’t be used for gaming with USB-C power. But there is a trick to game with it.
Launch the game with iGPU, then plug in the power. Yes, it's that simple.
It best suits students/mobile users who don’t want to lug the huge power brick to school/office and at the same time would like light gaming. You just need to bring around a 65W PD adapter
