The table below shows the possible laptop charging wattage from SOHO Dock when using Apple Type-C chargers. All SOHO Docks can dynamically adjust the pass-through charging capability based on the input Type-C charger and based on the USB devices connected to it. This table also can act as a guideline for other unmentioned 3rd party Type-C chargers plugged to SOHO Dock.
Please note that no charging may be possible if the Type-C charger is less than 18W.
