“We want to use the JCD543 docking station with an iMac Air with one monitor and an external drive for starters. I have a 65 Watt power adapter from a PC with a type C connector. Will this be enough for charging the iMac Air? Slower charging is okay.”

The JCD543 supports USB-C Power Delivery pass-through up to 100 W when used with a compatible USB-C power adapter connected to the dock’s “Power In” port. That means if you have a 65 W USB-C power adapter from a PC, it should work to charge your iMac Air, especially if slower charging is acceptable. The dock will negotiate power delivery with your iMac, and it can provide charging while you use external devices like the monitor and drive. A few notes to keep in mind: The total power available to your iMac may be less than 65 W after the dock uses some power for its own functions and any connected high-power peripherals. For the best performance when driving multiple displays or other power-hungry devices, using a power adapter closer to 90 W or higher (up to 100 W) is recommended.
