Compare charging adapters by the connection, stated output and charging protocol required by your device. A higher wattage printed on an adapter does not by itself establish compatibility with a particular phone.
Choosing Adaptor
How do you choose a fast mobile charger?
Check your device manufacturer’s supported charging protocol and power requirements, then match both the adapter and cable to those requirements. Check the listed output modes rather than wattage alone. Connector shape does not establish charging compatibility, and the device determines which supported mode it can use with compatible equipment.
Does USB-C always mean the same charging speed?
No. USB-C describes the connector shape, while power capability and charging protocols vary between products. A USB-C port can support different combinations of charging and data functions. Check the specifications of the phone, adapter and cable together; a matching plug alone does not guarantee a particular charging speed.
