The Panasonic Let's Note CF-SV7 supports USB Power Delivery 2.0 charging through its Thunderbolt 3 based USB-C connector which we tested using the Apple 87W USB-C Power Adapter while the PC is 2% charged. We observed a total of about 147 minutes for the Apple 87W USB-C Power Adapter to completely charge the Panasonic Let's Note CF-SV7 through USB Power Delivery.
When plugged in, the Panasonic PC could be seen to pull up to 50 watts from the Apple charger in the first hour of charging. After the next 14 minutes, the current decreased gradually to reach below .5 amps towards the end of charging.
