I believe everyone has a certain understanding of the power adapter, but what matters should be paid attention to when charging it? How to avoid those problems? Let's follow the editor to understand it!
1. Pay attention to the ambient temperature: try to avoid using it in the case of too high or too low temperature. You can refer to the working temperature of lithium-ion battery 0-35℃. Too low temperature will make the battery work unstable, insufficient discharge, and too high will Shorten the life of the electronic device and damage the battery.
2. Voltage matching: The rated output voltage of the mobile power supply is 5V. Generally, it should be controlled within the range of 5V±0.1V, otherwise it cannot charge part of the 5V load.
3. Current matching: The rated output current of the mobile power supply is generally divided into two situations. 1A current is used to charge ordinary mobile phones and smart phones, and 2A (or 2.1A) current is used to charge Apple series or tablet computers. At this time, if you use less than 2A The output power bank will cause the load to be dissatisfied, and the use time after charging is short. In this case, it is best to use a dedicated Apple series power bank. It is best to turn off the load with 2A/2.1A current output, because of the complexity of the function, it may not be able to charge when turned on.
4. The matching of the adapter: The mobile power supply charges the load through the USB cable. Therefore, the interface connected to the load must be the same as the load interface.
5. The quality of the cable: You must choose a USB cable made of international standard wires, otherwise, if the internal resistance of the USB cable is too large, it may cause too long charging time or even charging failure.
6. The charging environment should be in a ventilated place, and cannot be placed in a bag to charge the phone. Because a part of the energy consumption of the mobile power supply will turn into heat when it is charged, the heat dissipation effect is poor when it is placed in the bag. As mentioned earlier, excessive temperature will bring negative effects and even lead to safety accidents.
