A charger usually refers to a device that converts alternating current into low-voltage direct current. The charger is widely used in various fields, especially in the field of life, which is widely used in common electrical appliances such as mobile phones and cameras. The charger is a static converter device that uses power electronic semiconductor devices to convert alternating current with constant voltage and frequency into direct current. The charger has a wide range of application prospects in power applications where the battery is used as a working power source or a backup power source.
Chargers can be divided into three types: travel charger, car charger, and dock charger. The three chargers are briefly introduced below.
Travel Charger: short for travel mobile phone charger, a portable charger, suitable for travel, including use in other countries. So the charger input parameters should be 100-240V, 50-60Hz. The fast charge can only be used at a specific voltage.
Car charger: It is the abbreviation of car charger, that is, the charger used in the car. Usually one end is plugged into the car cigarette lighter, and the other end is directly connected to the charging device. Note the voltage that the car charger can use, small vehicles The provided input voltage standard is 12V. Under normal circumstances, the test range of our charger manufacturer is between 9-15V when debugging. The input voltage provided by some large vehicles is 24V. Our manufacturer tests in accordance with 28V. It should be noted that the low-voltage car charger cannot be used on a 24V vehicle. Otherwise, the internal parts of the charger will be damaged.
Dock charger: It is a relatively bulky mobile phone charger, often equipped with LED or LCD prompt function, and can be divided into single slot (only for mobile phones or only rechargeable batteries) and double slot (suitable for putting in the home Or in the office) two kinds.
The charger is a very convenient thing, no matter if you are traveling or on a business trip, you don’t have to worry about using your mobile phone, laptop, etc. It should be said that the charger provides a lot of convenience for everyone.
