Yes. It is normal for a 65W high-power charger to become slightly warm during use. The charger is certified to IEC 62368 safety standards, which helps ensure the exterior temperature remains within a safe range. 

For better heat dissipation, keep the charger well-ventilated and avoid direct sunlight or enclosed, high-temperature environments such as a parked car. 

If the charger becomes unusually warm, unplug it and let it cool to room temperature for 1 - 2 hours. Make sure nothing is blocking ventilation, check the port for debris, and gently clean it with a soft, dry, lint-free cloth if needed. You can also try a different cable, device, or wall outlet.
