In other words I want to plug the hub into my Macbook Air and the power into the Hub
[Power]-->[Hub]-->[2018 Macbook Air]
In either case the Macbook Air shows
AC Charger Information: Connected: Yes Wattage (W): 5 Charging: No
Okay so I tried a bunch of things. First off I'm using an Anker 60W Powerport 6 as power. I made the assumption, I guess wrong, that given the power adaptor that comes with the Macbook Air is 30W that this Anker 60W would deliver enough power. But apparently that's wrong. If I connect it directly to the Macbook Air it just says
AC Charger Information: Connected: Yes Wattage (W): 12 Charging: No
So, apparently the hub is taking 7W?
I plugged the Apple 30W USB-C Power Adaptor into the hub and I get
AC Charger Information: Connected: Yes Wattage (W): 19 Charging: No
So now the question is, if I go out and buy say the Apple 87W USB-C Power Adaptor and plug it in to the hub will in finally start charging through the hub?
