For those friends who rated it negatively in the reviews, no one mentions which charger they connected/combined it with from the back of the socket, as it does not come with a wall charger. On its own, it doesn't say anything. It is obvious that it will be slower with a regular charger and obviously this happens. The same thing happens to those who mention that it doesn't work with their mobile phones. It also requires the appropriate cable. The corresponding wireless model 50w xiaomi in China, as a member wrote in the questions, is sold in a set with the xiaomi charger at 67 watts and with a 6A cable, so that it can properly perform wirelessly, the whole set. It is mentioned on the manufacturer's page:
"For optimal performance, fast wireless charging requires Xiaomi 67W and 120W chargers. The output power can reach up to 50W with Xiaomi 12 Pro or Xiaomi 12."
So you will only see the 55W with the 120W charger behind it.
(I assume with the 67W charger, it will reach about 30W wirelessly).
These are as a "guide" and for any use of other wall chargers with it.
