Our 145W GaN Travel 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 

If this does not resolve the issue, please reach out to us at support@satechi.com
