With the development trend of automation technology, USB chargers are very common in daily life. To put it bluntly, the USB charger is that when the computer is connected to the USB port, the charging is carried out immediately by the USB on the computer. There is no blocky transformer, and the structure is very good. It's simple, much more convenient than the original charger. The essential equipment for home travel, the original transformer can also be discarded.
What are the advantages of USB chargers?
The benefit of the USB charger is that it can be charged and connected to the computer, which is very convenient. However, it is recommended that the charging should be done with a power socket, which can charge faster and prevents the computer from occupying the working voltage during charging. !
Everyone thinks which charger method is better to choose?
Obviously, some people use usb to charge and think it takes longer, but it is the cost of giving up the number of battery cycles. Therefore, which method to use, everyone should choose according to their own conditions.
Therefore, it is the best way to use genuine chargers as much as possible for Xiaomi everyone to carry out charging (USB can be used when necessary)

The advantages and disadvantages of well-known brand car chargers are relatively uniform. Everything is multi-faceted. The advantages and disadvantages of well-known brand chargers are shared:
Advantages:
(1) Because 2576 has built-in over-current protection, over-temperature protection and other safety precautions, 358 (dual operational amplifier) ​​is integrated to complete the output of constant current source CV, constant current power source CC, overvoltage protection OVP, etc.; Spectrum, safety, and sound lithium battery charging plan
(2) The constant current power supply CC and the overvoltage protection OVP are completed by operating the EN of 2576 according to the output of 358, so the charging current has a relatively large harmonic distortion, and the response time of CC and OVP is not fast (according to Is the conversion of 2576 completed during work?)
(3) Because 2576 is a fixed 52KPWMSPWM, it is very easy to make the EMI design of the car charger relatively easy.
(4) Because 2576 and 358 are both produced by 40V high-voltage bipolar processing technology, they are more "sturdy"
(5) This kind of planning scheme is commonly used in car chargers up and down from 0.8A to 1.5A;
(6) A fully integrated planning scheme dedicated to on-board chargers, with low-cost system software and high stability
(7) The internal CV, CC, and OVP of the IC are all based on PWM control; therefore, the output voltage, output current, and output over-voltage protection have higher precision and quick response time
(8) Xinlong provides a series of cost-effective products for car chargers between 0A and 2A.
9) The advantages of appearance, compactness, miniature, and easy to use, are all called ultra-small well-known brand car chargers
