Different power
The difference between 65w super flash charge and 40w wireless flash charge is that the power is not the same. 65w charging speed is much faster than 40w charging speed.
For example, if 65w is charged with a 4000 mah battery, it generally takes only about half an hour to be full, and if it is 40w, it takes about 40 minutes to 50 minutes to be full.
Of course, 65 watts fast charge is much faster than 40 watts, the higher the wattage, the greater the power, the faster the charge
