The main thing is that the power of the charger is different. It is obvious that the 50 watt charger power is almost twice the power of the 27 watt charger, so the charging time is obviously faster when charging, and the charging current is also relatively large. At the same time, the heat is obviously low, and the use is obviously safe and reliable, so use a 50-watt charger as much as possible.
Charging power is not the same, 27w with 3a charging line can be, 50w needs 5a charging line, 50w charging speed is faster
