Xiaomi's 30 watt wireless charger should still be equipped with Xiaomi's original 30 watt charging head, so that their voltage and current output are matched, I can guarantee that the output voltage of your mobile phone is also a very stable voltage output, but if I have Xiaomi's original 300,000 watt charging head, it is better to plug the phone directly to charge it
Preferably with an output of 10V, 3A
