If your mobile phone can accept the maximum power is 22.5W, then 22.5W and 66W, the two chargers for your mobile phone charging speed is the same, or 22.5w charging effect may be better than 66W, because it is a charger suitable for your mobile phone.

If your phone can accept the maximum power is 300,000, then its charging effect should be 66 watts faster, because the general charger used by the fast charge protocol is backward compatible
For this problem, it must be that the charging speed of 66 watts will be faster, because 66 watts, its power is higher, so it means that its voltage or current will certainly be larger, so under the conditions of the same battery capacity, the greater the voltage or current, its charging speed will certainly be faster, in general, A 66 watt charge will certainly be about twice as fast as a 22.5 watt charge
Ideally, when the battery capacity is the same, the 22 watt charger takes about 50 minutes to full, while the 66 watt charger takes only 30 minutes. (This is all with mobile phone support.)
