With the continuous development of technology, modern mobile phone chargers are becoming more and more powerful. But when we use a 120W charger to charge a phone with only 33W power, does it harm the phone? This article will discuss this issue and analyze the stakes.
Questions asked
In the market, we can often see a wide variety of mobile phone chargers, with power ranging from a few watts to a hundred watts. For some high-power chargers, people may have a question: Is it possible to charge low-power mobile phones with high-power chargers? Taking a 120W charger to charge a 33W mobile phone as an example, will this practice harm the phone?

Problem analysis
Before answering this question, we need to understand the basic principles of mobile phone charging. The process of charging a mobile phone is essentially a process of converting electrical energy into chemical energy. When the charger power is greater than the maximum accepted power of the mobile phone, excessive current may cause damage to the mobile phone battery and affect the battery life.
The 120W charger is designed to provide power to devices of 120W and above. If it is used to charge a 33W phone, then the output current of the charger may reach several times that of the phone. Although modern mobile phone chargers have a certain overload protection function, this high current impact can still cause damage to the mobile phone.
solution
In order to avoid the damage caused by using a 120W charger to charge a 33W mobile phone, we can take the following two schemes:
1. Use the original charger: In order to ensure the safety and longevity of the mobile phone, each mobile phone manufacturer will equip its mobile phone with the original charger. The power and current of the original charger are most closely matched to the mobile phone and can protect the mobile phone battery to the greatest extent. Therefore, in order to prevent battery damage, we should try to use the original charger.
2. Reduce the charging power: If the situation is special and you must use a 120W charger to charge a 33W mobile phone, then we can try to reduce the output power of the charger. Most chargers support multi-level output, and we can adjust the power of the charger to match the power of the mobile phone when charging, so as to avoid the impact of high current on the mobile phone.
conclusion
To sum up, a 120W charger charging a 33W mobile phone may cause damage to the phone battery. To avoid this damage, we should try to use the original charger and reduce the output power of the charger when we must use a high-power charger.
In real life, the selection and use of mobile phone chargers should be flexibly adjusted according to specific circumstances. At the same time, we should also understand and pay attention to the relevant technological development of mobile phones and chargers, so as to update our devices at the right time and enjoy a better charging experience.
