33W, 65W, 120W charging jako it as binding? let's stop with that

these are only:
1) inscriptions on the adapter
2) sudden power that the adapter is able to provide in one short moment (first few seconds / tens of seconds) when the battery is fully discharged, when the battery is fully charged, the power decreases (current or voltage), or otherwise: the charging curve is NOT constant

absolute, however, does not say what the power will charge the smartphone…. ehm, actually, they say, SURE, MENSIM!

The AccuBattery app shows the current which, after the voltage transformation by the phone's circuits, goes to the li-ion battery of the smartphone, and as we know it has a nominal voltage of 3,6-3,7V.

so my own experience: Redmi Note 10 Pro, 33W charger. On the original charger, there are several modes (speeds, performance) of charging, specifically these five:
15W as 5V * 3A
27W as 9V * 3A
27W as 12V * 2,25A
27W as 20V * 1,35A
33W as 11V * 3A (this is the maximum)

At the beginning of fast "33W" charging with the ORIGINAL included cable, AccuBattery says that the current is up to 5,7-5,8A (at 1% charge), then it drops to approx. 1,5-2A (at 100% charge)
with nominal 3,6V li-ion monoclans we have the beginning of charging at about 21W and the end at 5-7W
and where is at least the beginning at 1% coating charge at 33W? answer: they evaporated during the conversion of currents and voltages in thermodynamic nothingness in the framework of 21/33 = 64% efficiency

control: 5000 mAh at 3,6V = 18 Wh and the battery is charged from 0% to 100% with this "so-called 33W fast charging" in 75 minutes, ie 1 and 1/4 hours, but 18/1,25 = 14,4 W... otherwise it sits quite nicely like a butt on a serbelik when I guessed something between 13-14W

total sum total
1) due to the NE constant of the charging curve (max. Power is IBA at the beginning of charging and then decreases to about one-third-quarter)
a
2) due to about 2/3 of the charging efficiency itself

from 33W charging became 14,4W charging, which is about 44% (in the word STYRIDSAT STYRI PERCENT from the declared and marketing tumble value of 33W)

and now let's realize how efficient and average power they charge those amazing 65W and 120W fast chargers: a model example?
120W 11TPro supposedly in 17 minutes, someone succeeded in the review in 17 and a half minutes, some after 23 minutes, let's give it an average of 20 minutes

abbot we have 5000 mAh flashlight what is 18 Wh in 20 min (1/3 hours) to mame 18 / (1/3) = 54 W… KRAAAAAASA
it fits like an asshole on the screen, from the declared and marketing-denominated value of 120W remained effective and averaged charging power of 54W… and now it comes: 54/120 = 0,45 (ie the word STYRIDSAT PAT PERCENT)

everything is clear

also:
not 33W but 14W charging, because it is rough, averaged, efficient performance by how to charge the battery from 0% to 100%
not 65W but 30W charging, because it is rough, averaged, efficient performance by how to charge the battery from 0% to 100%
not 120W but 54W charging, because it is rough, averaged, efficient performance by how to charge the battery from 0% to 100%
