First of all, you must first clarify the fast-charging power and fast charging protocol supported by your mobile phone;
Second, you have to confirm whether your charger supports the charging protocol of your phone;
Finally, check whether your charging cable supports the current at the charging power, and then confirm the interface.
Example 1: iPhone11Pro,
First step: see if the phone supports PD fast charging 18W,
Second step: see if the charger 65W supports PD protocol,
Third step: the fast charging line must be a Type-C to the Lightning port,
If all the conditions are met, then this 65W charger can charge iPhone11Pro with an 18W fast charge.
Note: If you use a USB-A to Lightning charger/cable, PD fast charging is not possible, even if the power is higher, the charging speed is up to 10W at this time.
Example 2: Huawei 40W fast charge mobile phone,
First step: check out if the phone supports Huawei’s fast charge 40W,
Second step: check out if the charger 65W supports the Huawei Super Fast Charge SSCP protocol,
The third step, the fast charging line is the 5A current line (super thick) of the USB-A to Type-C port,
If all conditions are met, then this 65W charger can charge your Huawei mobile phone with a 40W fast charge.
Note: If the charger does not support the SSCP protocol but only supports the SCP protocol, it will not be able to charge 40W. In addition, if a thinner 2A current line is used, the USB-A to Type-C interface will also not charge 40W.
Summary: The charger’s power of 65W is greater than the mobile phone’s charging power of 33W does not mean that it will be able to charge 33W. First of all, it must be clear that the mobile phone’s fast charging protocol is perfectly supported by the charger, and secondly, the correct charging cable must be used so that your mobile phone can quickly charge His own greatest effect.
