Wireless charger is the abbreviation of wireless charger, English Wireless Charger. Wireless charging is a device that uses the principle of electromagnetic induction for charging. Its principle is similar to that of a transformer. By placing a coil at the sending and receiving ends, the sending end coil sends an electromagnetic signal to the outside under the action of electric power, and the receiving end coil receives the electromagnetic signal And the electromagnetic signal is converted into electric current, so as to achieve the purpose of wireless charging. However, the export of wireless chargers to the United States generally requires FCC-ID certification.

A wireless keyboard refers to a keyboard that performs wireless transmission through the Bluetooth protocol and performs Bluetooth communication within an effective range (within 10m). In fact, it is a short-distance radio technology, using \"Bluetooth\" technology, can effectively simplify the communication between handheld computers, notebook computers and mobile phones and other mobile communication terminal devices. However, if you want to export wireless keyboards to Japan, you need to apply for MIC certification.

In recent years, with the improvement of people\'s consumption level, the sales market of wireless headsets has also become larger and larger. Compared with wired earphones, wireless earphones have little difference in sound quality, but wireless is more convenient, mainly because the middle line is replaced by electric waves. The wireless earphone is the middle wire is replaced by the electric wave, which is connected from the audio outlet of the computer to the transmitting end, and then sent from the transmitting end to the earphone at the receiving end through electric waves. However, the export of wireless products such as wireless headphones to Europe requires CE-RED certification.

Wireless projector refers to a projector that takes wireless transmission technology as its core and realizes projection through wireless transmission. Through the wireless module, connect to the projector through the HDMI socket, through the wireless projector, the screen on mobile phones, tablets, computers and other devices can be synchronized to display or transmit music, videos, pictures and other content to the large screen in real time. On the premise of not losing the quality of the projection image, to provide users at all stages with a trendy and convenient application experience. EMC testing is required. Welcome to ZRLK testing for processing!

FCC-ID is one of the compulsory FCC certification models in the United States and is suitable for wireless products. Products with wireless transmission frequencies, such as Bluetooth devices, WiFi devices, wireless alarm devices, radio receiving and transmitting devices, phones, computers, etc., need to apply for FCC-ID certification. The certification of wireless products is directly approved by the FCC TCB agency, and the certification can be checked on the official website of the FCC in the United States.

The wireless charger is a device that uses the principle of electromagnetic induction for charging. Its principle is similar to that of a transformer. By placing a coil at the transmitting and receiving ends, the transmitting end coil sends an electromagnetic signal to the outside under the action of power, and the receiving end coil receives the electromagnetic signal. Signal and convert electromagnetic signal into electric current, so as to achieve the purpose of wireless charging. Wireless charging technology is a special power supply method that does not require a power cord and relies on electromagnetic wave propagation, and then converts the electromagnetic wave energy into electrical energy, and finally realizes wireless charging. However, the export of wireless chargers to Europe requires CE certification before they can be sold.

With the continuous development of technology, many smart electronic products are moving towards wireless. Wireless products can effectively make up for the shortcomings of wired products and are welcomed by most people. However, different countries where wireless products are exported need to apply for different certifications. Let\'s take a look at the EU CE certification and US FCC certification that wireless products want to enter the European and American markets!

The mobile power bank (Power Bank) is a combination of batteries or battery packs, corresponding circuits and casings. It can provide a non-fixed power system with stable DC output and a power bank that does not exceed 18kg and can be carried by the user. Mobile power is commonly known as power bank; it is a portable charger that integrates power supply and charging functions. It can charge mobile phones, tablet computers and other digital devices anytime and anywhere. However, when the mobile power supply encounters collision, extrusion, high temperature, etc., it is very prone to smoke and fire due to the internal short circuit of the lithium battery. In order to ensure the quality and safety of mobile power, before the mobile power enters the market, it needs to be tested by an authoritative third-party testing and certification organization to verify the product quality and safety.
