The Qualcomm official website has a list of all devices that officially support Quick Charge 4.0 charging. You can download the list from this link. About the fact that there is Xiaomi Mi 8 and Xiaomi Mi A2 I know it well, but quite unexpectedly appeared on it Pocophone F1. The cheapest smartphone in the world with Snapdragon 845.
The Pocophone F1 supports the Quick Charge 4.0, just like the Mi 8
If you are the owner of a Pocophone smartphone and want to use the full potential of charging, you should buy on your own a charger that supports Quick Charge 4.0 and here is the problem. Availability of chargers adapted for QC 4.0 is very limited. If you have a link to a proven charger with QC 4, share it in a comment, help others. I recommend the product Blitzwolf but supports only QC 3.0, the manufacturer does not offer chargers in newer technology yet.
The charger we receive with the F1 smartphone is only compatible with the Quick Charge 3.0. The word is only a bit exaggerated, there is a company that offers much more expensive smartphones and inserts free chargers into the box.
