A 55W charger can charge a 33W phone, but whether it is fast charging depends on.
1. if the 55W charger is not compatible with other fast charging protocols, then when using this charger to charge a 33W phone, the charger can only provide a maximum output of 10W (5V/2A) for the phone.
2, if the 55W charger is compatible with the 33W fast charging protocol, then this charger can provide fast charging for the phone, and the charging speed is comparable to the phone's original charger.
3, if the 55W charger and 33W phone at the same time downward compatible with other fast charging protocols, such as 22.5W, 18W, etc., then the charger will automatically match the fast charging protocol with the phone and perform fast charging.
Next, let's look at how a 55W charger charges a 33W phone through text.
When the 55W charger is connected to the 33W phone, the charger will output 5V voltage and 2A current, which is the standard charging scheme for smartphones, or what we often call ordinary charging.
The charger will read the phone's fast charging protocol after it establishes a connection with the phone and compare it with its own compatible protocol. If both support the same fast charging protocol, then the charger will switch from normal charging to fast charging by providing the relevant current and voltage to the phone according to the protocol; if the phone does not support fast charging or both are not matched to the same fast charging protocol, then the charger will keep providing 5V voltage and 2A current to the phone until the end of charging.
Therefore, the 55W charger is perfectly capable of charging a 33W phone. As to whether it is fast charging, it needs to be decided by the phone, charger and data cable.
