Can I charge my phone with laptop charger?

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.04.16
Nowadays, laptop power supplies usually use the Type-C interface, which is the same charging head as the phone interface. However, sometimes we often forget to bring a phone charger when working. If the phone runs out of battery, can we use a laptop charger to charge it?



Some people think it's possible because after all, the interfaces are the same. Both mobile phones and laptops are essentially lithium batteries, so they can naturally charge each other.

But some people also believe that the power of a laptop charger is different from that of a mobile phone charger. Usually, the power of a laptop charger is greater than the output power of a mobile phone charger, which can damage the phone.

So, can a laptop charger actually charge a phone?

The answer is yes!

If you are a careful netizen, you will find that the output power of laptop chargers is usually compatible with multiple voltages and currents, and their charging range is very wide. Taking Huawei laptop chargers as an example, their output power is compatible with 5V2A, 9V2A, 12V2A, 15V3A, and 20V3.25A, which is equivalent to this charger being able to charge most mobile phones or laptops.

That is to say, as long as these output powers match the output power of the phone, they can charge each other. It can be seen that the output power of the first 5V2A is the most commonly used output power, so it is definitely possible to charge the phone. Huawei chargers, on the other hand, are versatile and can charge phones, tablets, and laptops together.

However, it should be noted that different phones may require different charger powers and charging cables, so it is best to use the original charger that comes with the phone or a charger with good compatibility.

In addition, some chargers may not support fast charging function, so the charging speed may be slower than using the original charger. In short, to ensure the safety and effectiveness of mobile phone charging, it is recommended to use an original charger or a certified compatible charger, which may be better!
