What is the difference between USB charging and plug charging

The difference between USB charging and plug charging: 1. Different voltage stability, USB charging has better voltage error and stability than plug charging; 2. Different currents, USB charging has a lower current than plug charging, and slight voltage fluctuations will not have any impact on charging. Pulse fluctuation charging for a certain period of time is very beneficial to the battery; 3. The charging speed varies. The maximum current for USB charging can only be 500ma, while plug charging often exceeds 500ma, usually between 800-1200ma. USB charging takes longer while plug charging takes shorter time.

With the development of technology, digital products have become very common in our lives. As commonly used electronic products in our daily lives, digital products need to be charged frequently. During the charging process, we sometimes use a charger to charge directly, and sometimes we use a USB interface to charge. So, what is the difference between charging with USB and charging with a charger?

1、 Different voltage stability

Compared to chargers, computer USB voltage has very small errors and is also very stable. In this regard, voltage error and stability are much better than chargers.

2、 Different currents

All USB voltages on the computer are 5V DC, but small wires are used to power the front of the computer. If inferior wires are used, sometimes there is a fear of insufficient current, rather than insufficient voltage, which may cause heating. The back of the computer is led out from the motherboard, and the copper skin is thicker, so there is no concern about heating up. For charging, slight voltage fluctuations will not have any impact on charging. To be precise, pulse fluctuation charging for a certain period of time is very beneficial for batteries, especially for lead-acid batteries and nickel hydrogen cadmium batteries.

3、 The difference in charging speed

Charging through the USB interface of a computer can only supply a maximum current of 500mA, while charging through a charger often exceeds 500mA, with many chargers typically ranging from 800-1200mA. That is to say, charging through the USB interface of the computer will take longer, but if your charger provides a current greater than 500mA, the charging time will be shorter.

What is the difference between charging with USB and charging with a charger? Share it here. Excessive current during charging often causes the battery to overheat or even explode. Due to the limited current or current protection circuit often added to chargers, there is no need to worry when using chargers, but it is best not to use universal chargers and inferior chargers.
