Using a 120W charger to charge a 33W phone may cause some problems. First of all, we need to understand the charging protocol matching problem between the charger and the mobile phone.
The charging protocol does not match.
Modern mobile phones often have their own charging protocols to ensure safe and efficient charging. If there is a mismatch between the charging protocol between the 120W charger and the 33W phone, then there may be a problem with charging. For example, a charger may charge a phone at an inappropriate voltage or current, which can cause slower charging or even negatively affect battery life.
Charging speed issues.
Even if the charging protocol is matched, when a 120W charger charges a 33W phone, the charging speed may not be as fast as using a 33W charger. This is because the power of the charger is greater than the required power of the phone, which may cause heat up while charging, which can affect the battery life.
The charger is overheating.
When using a high-power charger to charge a low-power phone, if the power of the charger is much greater than the required power of the phone, it may cause the charger to overheat. Prolonged use may negatively affect the life of the charger and battery.
To test the above point, we conducted a simple experiment. We used a 120W charger to charge the 33W phone and observed the changes during the charging process. The results of the experiment showed that when using a 120W charger to charge a 33W mobile phone, the charging speed was not significantly faster, but slower than that of a 33W charger. In addition, the charger heats up significantly during charging, which can negatively impact battery life.
To sum up, while charging a 120W phone with a 33W charger will not cause direct damage to the phone, it may have a negative impact on the charging speed and battery life. Therefore, in order to ensure the safe and efficient charging of the phone, we should use a charger that matches the phone.
