Product Parameters
Temperature power-off test
The USB-C connector end of this fast charging cable comes with a smart temperature control protection chip. If the cable encounters a malfunction when charging the mobile phone, it can intelligently cut off the charging current when the temperature is too high, and the charger stops charging the mobile phone. Prevent danger from occurring at the root cause. Compared with the traditional way of using PTC thermistor, directly cutting off the charging current can further ensure the safety of the mobile phone. Let's actually test it below.
Use our A to C fast charging cable to participate in the test. At the beginning of the test, the current is passed through the wire with a magnitude of 3A, and the temperature inside the box is raised. When the temperature of the test meter continues to rise to 87.2°C, the current and voltage suddenly return 0, the test stops at this time.
This is because the temperature control probe inside the wire detects that the plug temperature is greater than or equal to the set protection temperature, and then the main control IC sends a command to the switch MOSFET to turn off the output. So as to avoid the potential safety hazards on the equipment side caused by the temperature rise again. Completely shut down the way to charge the mobile phone to achieve zero power output.
The wire can be turned off when the temperature is too high when transmitting a large current of 3A. The following is an actual measurement of whether it will be turned off when transmitting a current of 5A. Other test conditions remain unchanged. The transmission current of 3A is increased to 5A. During the test, it is found that when the temperature of the test meter continues to rise to 79.3°C, the current and voltage suddenly return to 0, and the test stops at this time.
The above test is aimed at increasing the temperature of the USB-C connector to test whether the intelligent temperature control protection chip inside the wire will work. In fact, there is another possibility that the temperature rises, that is, there is a short circuit in the USB-C connector of the wire. At this time, the main control IC will issue a command to the switch MOSFET to turn off the output, avoiding greater safety hazards.
Let's take a look at the A to C fast charging cables of other brand manufacturers. The test conditions are still the same, except that the tested wire is replaced with other A to C fast charging cables. During the test, the temperature inside the box continues to rise. When the temperature of the test meter has reached 96.8°C, the current and voltage can still be seen continuously output. For the safety of the test, the editor stopped the test at this time.
The temperature of the plug has reached 96.8°C! Continue to output power!

FAQ
Question: what is voltage drop?
Answer: The voltage drop of the cable is the phenomenon that the voltage generated by the power is reduced after a distance of the cable transmission.The reason for the voltage drop is that the cable has resistance.
Question: what is the effect of the volage drop?
Answer: The smaller the volage drop, the larger the charging power.The intuitive performance is that the charging speed is faster under the same conditions.
