Our 165W GaN Charger detects what device is plugged in and will recalibrate power allocation to provide the necessary wattage for each connected device. 

If a device stops charging, we recommend the following: 

1. Unplug all devices & cables from the charger then unplug the charger from your power source 
2. Connect each device individually with the largest device connected to PD #1 

Port Schematics are as followed: 

1 x USB-C PD connected - up to 100W
2 x USB-C PD connected - up to 100W/60W
3 x USB-C PD connected - 60W/60W/45W or 100W/30W/30W
4 x USB-C PD connected - 60W/45W/30W/30W
up to 165W total
