The required power adapter depends on your laptop's charging needs. The hub supports a maximum input of 100W and consumes 15W for operation, with the remaining power available to charge your laptop. For optimal charging:· A laptop that requires 85W should use a 100W PD charger and a 100W cable (15W for the hub + 85W for the laptop).· A laptop that requires 65W should use an 80W PD charger and an 80W cable (15W for the hub + 65W for the laptop).Make sure both the charger and cable meet the wattage specifications for efficient charging.
