There’s a catch though. In order for it to work at 10W, it has to be connected to adaptive fast charger from Samsung which has a spec of 9V 1.67A.
You anyhow connect to 5V 2A charger will only give u 5V 1A wireless charging which equates to 5W.
for this, i bought the samsung fast changing adapter and their usb c cable to connect to samsung wireless charger.

Guess iPhone X gonna pop it's cherry.
