Millet 30w wireless charger charging head how many watts? 45W
The power of the Xiaomi 30W wireless charging head you said is 45W, which is the input power, the input voltage is 20V, and the input current is 2.25A. Instead of the output power, the output power can only reach 30W. This is because there is resistance in the charger, which will lose a certain amount of power. These are my answers.
Just use a 25-watt charger charger
