Anker is dominating USB-C wall charger sales on Amazon. I do a monthly post on the best selling USB-C power banks and chargers. Checking best sellers for May I found a lot of Anker products.
For USB-C wall chargers 11 of the top 100 are USB-C. The rest are USB-A, which I skip. Out of those top 11 USB-C chargers 8 were Anker. Including spots 1 through 6.
- PowerPort PD 2
- PowerPort Atom PD 1
- PowerPort Atom PD 2
- PowerPort+ Atom III
- PowerPort Speed PD 5
- PowerPort II PD
- PowerPort Speed+ Duo
- PowerPort Speed PD 30
For power banks the PowerCore 10000 PD and PowerCore+ 26800 PD made the top 5 list.
