To realize the wireless charging of mobile phones and other products, there must be two parts at present: the transmitter, which is connected to the power supply, is responsible for transmitting electric energy to a wide space; the receiver, generally installed on the electronic product, is used to receive electric energy. Currently, wireless charging technology has begun to be used in mobile phone products. Take the iPhone as an example. Now that wireless charging manufacturers have wireless charging functions, they have been modified to install a similar type of “Apple skin”. "clothes". As a wireless charging receiver, it is presently in the form of an increase in the charging of mobile phone casings, but related transformation products may be launched in China this year. Currently known as the “Qi Gate,” this case supports iPhones and BlackBerrys. Users do not need to change their phones to experience this feature first. At the end of this year or early next year, the wireless charging receiver will be fully "thin" and become a wireless charging receiver chip built into the mobile phone product, which is only as large as a fingernail cover. At present, Nokia, Philips, LG, Samsung, Sony Ericsson and RIM, and many other internationally renowned mobile phone manufacturers support this technology. Wireless chargers may also be bundled with mobile phones for sale.
