I recently bought a Xiaomi Mi Note 10 without the original charger.
I thought and 30W would charge my phone fast as the original charger.
Diving in, I understood that Xiaomi's "fast charging" is (i think) a proprietary fast charging protocol (although the Snapdragon 730G does support QC4+).
The original charger supports the following outputs: 5V-3A, 9V-3A, 12V-2.25A, 20V-1.35A, 10V-3A.
The cable is a standard USB on the charger side and a USB-C on the device side.
I would like to buy a charger (home and car) that would charge the phone at it's best.
Having non-standard fast charging protocol, I really don't know which charger should I be buying.
Would appreciate some help.
