What is the difference between charging with USB and charging with a charger?
Different voltage stability: Compared with the charger, the USB voltage of the computer has a small error and is stable at the same time. From this aspect, the voltage error and stability are much better than the charger.Different current: All the usb fast charging station of the computer are DC 5V, but the front of the computer is powered by small wires. If you use inferior wires, sometimes you are afraid that the current is not enough, not the voltage, which will cause heat. The back of the computer is drawn from the motherboard, and the copper skin will be thicker, so there is no heat concern. For charging, a slight fluctuation of voltage will not have any effect on charging. To be precise, pulse fluctuation charging for a certain period of time is very good for batteries, especially for lead-acid batteries and nickel-metal hydride nickel-cadmium batteries.
The difference in charging speed: charging through the 30 port usb charger of the computer, the maximum current supplied to the computer can only be 500mA, while charging through the charger often exceeds 500mA, and many chargers tend to be 800--1200mA. That is to say, charging through the computer's USB interface will take longer. If your charger provides a current greater than 500 mA, the charging time will be shorter.
