You can check whether the charging head supports fast charging in the following ways: 1. Check the logo of the charging head: The charging head is usually marked with the words \"Quick Charge\" or \"QC\" on the housing.
2. Check the output voltage and current of the charging head: The output voltage and current of the fast charging head are higher than that of the ordinary charging head. For example, the voltage of the fast charge 3.0 is 3.6V-12V and the current is 3A, while the voltage and current of the ordinary charging head are usually around 5V and 2A. 3. Use professional tools for testing: there are some professional testing tools that can test the fast charge function of the charging head, such as the Android APP \"Ampere\".
You can use the above method to check whether the charging head supports fast charging. However, it should be noted that even if the charging head supports fast charging, the phone or device itself needs to support fast charging to achieve fast charging.
1 Check whether the output power of the charging head meets the fast charge standard. 2 The output power of the fast charge head should reach 18 watts or more, and support related fast charge protocols, such as QC2.0\/QC3.0, PD, etc.
3 Pay attention to the product parameters when purchasing the charging head, or you can determine whether the charging head supports the fast charge function by using a professional fast charge detection instrument.
one
By actually recording the phone charging time. According to the experience of use, if you start charging when the power is 0~10%, after half an hour or so, the phone power can be basically restored to about 60%, and the device can be basically judged to be fast charged.
two
The DC input voltage of the charging interface is 5V±5%, and the maximum absorbed current is 1800mA. As long as the output of the adapter breaks through this condition, it is fast charging.
three
Download a software that detects charging, and you can see the charging temperature, voltage, and whether the device has a fast charge.
