MacBook – Can you charge a 2018 Macbook Air through a USB-Hub

chargingmacbook pro

In other words I want to plug the hub into my Macbook Air and the power into the Hub

[Power]-->[Hub]-->[2018 Macbook Air]

I bought 2 hubs and neither seems to be able to do this. I tried a VANMASS 9-in-1 USB HUB and a Sicotool 8 in 1 Type C Combo USB C Hub Adapter

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?

Answer: Yes, I went to the Apple store, plugged on the Apple 60W USB-C Power Adaptor and System Info shows the Macbook Air was charging.

So I guess the 60W Anker is not 60W for a single port
