The charger is a device used to input energy into the battery by forcing current through it. Usually refers to a device that converts AC power into low-voltage DC power, which is widely used in common electrical appliances such as mobile phones and cameras. The charger uses power electronic semiconductor devices to convert alternating current with a fixed voltage and frequency into direct current. The charger has a wide range of application prospects in the electric occasions where the battery is used as the operating power source or the backup power source. When the charger is exported to the market in my country, it must be compulsory 3c certification conforming to my country\'s laws and regulations. The charger is in the second category of the 3c certification catalog, which requires 3c certification.

The \"CE\" mark is a safety certification mark and is regarded as a passport for manufacturers to open and enter the European market. CE stands for CONFORMITE EUROPEENNE. All products affixed with the \"CE\" mark can be sold in the EU member states without having to meet the requirements of each member state, thus realizing the free circulation of goods within the EU member states.

The basic requirements for the transportation of lithium batteries: (1) Lithium batteries and lithium battery packs are classified as Class 9 dangerous goods; (2) All lithium batteries (groups) must pass the UN38.3 test; (3) Some Class 9 dangerous goods Exceptions are provided for the transportation of lithium batteries; (4) Strict restrictions on transportation samples; (5) Restrictions on daily-use lithium batteries carried by passengers; (6) Restrictions that all defective or damaged batteries are prohibited from being transported.

Types of batteries tested: nickel-metal hydride batteries, nickel-cadmium batteries, alkaline manganese batteries, fuel cells, dry batteries, button batteries, lithium ion batteries, mobile phone lithium batteries, import and export batteries, notebook batteries, and two batteries containing alkaline or non-acid electrolytes Secondary cell; Test items: impact test, height simulation test, overcharge test, temperature test, forced discharge test, external short circuit test. Impact test, vibration test.

KC certification implementation standard of display power supply: KC60950

Mobile power KC certification implementation standard: KC62133

Batteries often have to enter UL certification before entering the US market. Although UL certification is voluntary, the US Customs releases products with the \"ul\" mark. Without this mark, complicated inspection procedures are required. And when a safety incident occurs, the Fire Product Safety Committee (CPSC) will also use UL standards as the basis for judgment. Therefore, in the United States, many sellers refuse to sell products without the \"UL\" mark in order to avoid trouble. As a component of electrical products enters the United States, batteries require UL certification.

Battery products are very popular in the European Union. The export of battery products to the EU requires CE certification. The CE certification directive for batteries is 2006/66/EC, the battery EMC directive EN61000 battery safety standards: EN62133, EN60950. 2006/66/EC directive The battery products are divided into four categories: portable batteries, button batteries, industrial batteries and automotive batteries.
