The mophie Powerstation USB-C XXL is now sold through the Apple Store so let's see how it supports charging from the non USB Power Delivery enabled USB Type-C port on the Henge Docks Stone.
With 50% battery charge on the mophie Powerstation USB-C XXL, we connected it to the USB Type-C port at the back of the Stone which provides non USB Power Delivery charging up to 10.5 watts. The Stone was observed to deliver a steady state charging of about 7.5 watts to work fine with the mophie Powerstation USB-C XXL.
