What is charger?

Charger refers to a travel charger, which is a device designed to provide energy for power storage devices. It mainly uses power electronic semiconductor components to convert alternating current with fixed voltage and frequency into direct current. flow device. When charging the mobile phone battery, the travel charger must pay attention to the fact that the output voltage of the power supply must be within the specified range, otherwise the charging function cannot be realized.

The English name of a travel charger, Charger, usually refers to a device designed to provide energy for electrical storage devices. The travel charger is a static converter device that mainly uses power electronic semiconductor components to convert alternating current with fixed voltage and frequency into direct current.

With the rapid development of the global economy, more and more people are traveling, and there are more and more portable electronic products, such as mobile phones, digital cameras, MP4, GPS, travel chargers, etc. all use batteries, but the batteries that come with these devices will not be able to meet the normal use time of the device due to low battery capacity. However, the emergence of travel chargers has solved this problem very well. question. In power consumption situations where batteries are used as working power sources or backup power sources, chargers have broad application prospects.

Types

There are many chargers, such as battery chargers, travel chargers, car chargers and external battery chargers and other external battery chargers, also called " "External battery", mobile power charger was developed with the popularity and rapid growth of digital products. Its definition is a large-capacity portable power supply that is convenient and easy to carry. With this charger, you can provide power (power supply or charging) to a variety of digital products anytime and anywhere while on the move.

Battery chargers such as batteries are mainly electrochemical devices that store chemical energy and release electrical energy when necessary. This battery mainly immerses the anode (PbO2) and cathode (Pb) in the lead-acid battery into the electrolyte (dilute sulfuric acid), and generates 2V of electricity between the two electrodes to achieve functions such as charging and discharging. The shapes and sizes are different, and some cannot be directly of use for the second time.

Car charger, also known as car charger, is a mobile phone charger accessory that is used to facilitate car owners to use car power to charge digital products anytime and anywhere when traveling. Some high-end car chargers generally include two USB ports, which can charge two digital products at the same time. This type of product generally has overload protection, short circuit protection, high voltage input protection, high temperature protection, and quadruple safety protection functions to ensure safe use. The car charger can be used in the car as well as at home, realizing the three-in-one multi-functional use of car charging, direct charging, and USB charging

Notes

1) When charging the mobile phone battery, the travel charger should pay attention to the fact that the output voltage of the power supply must be within the specified range, otherwise the charging function cannot be realized.

2) Keep the charger dry, because rain, moisture and various liquids or moisture may contain minerals that will corrode electronic components and circuits.

3). Do not place it in a high temperature place. High temperatures will shorten the life of electronic devices, damage batteries, and degrade some plastics.

4) When purchasing a travel charger, it is best to go to a specialty store (counter) authorized by the manufacturer to ensure that you buy original accessories of authentic quality. Random selection may cause the electrical appliance to be charged to be less than optimal, and in severe cases may even affect its normal use.
