The advantages of USB charger – phone charger wholesale

The current mobile phone is charged in two modes. One is direct charge and the other is USB charge. However, some people say that they are not satisfied with USB charging, and they are also easy to lose power. Let us talk about the advantages of USB charger today. USB phone charger is very common in daily life. The USB charger is connected to the USB interface on the computer and is directly charged by the USB of the computer. There is no big transformer, and the structure is very simple, which is much more convenient than the original charger.

But no matter what, electronic devices will have a certain life span, and USB chargers have a long life. In general, the effect of the rechargeable battery will gradually accumulate with the effect, leading to a substantial reduction in the actual capacity of the battery, and will also reduce the side effects of the memory effect. The effect of nickel-cadmium battery is the most obvious. It is recommended that when using this type of battery, it needs to be used repeatedly for 5 to 10 times before it can be discharged. Nickel-metal hydride batteries are different and can be used repeatedly after 20 to 30 times. The capacitor in the USB charger uses a nickel-hydrogen electrolyte, which takes a long time to be used in the process of use, resulting in a long service life.
