Big Bit Guide] Apple’s new MagSafe magnetic wireless charging technology, which nakedly raises the added value of wireless charging, broadens the vast future and imagination of wireless charging. On October 14, Apple held a global online press conference.

The iPhone 12 series released at the conference are equipped with the new MagSafe magnetic wireless charging technology, and the wireless charging of Apple mobile phones has been upgraded from the previous 7.5W to 15W power fast charging experience .

The MagSafe magnetic wireless charger has a magnet inside the iPhone 12 that attracts each other, and it can automatically align the transmitter coil and the receiver coil when it is close, and transmit energy through the air after being firmly absorbed. The MagSafe magnetic wireless charger comes with a power supply cable. A TPE material cable extends from the metal base.

The interface is a new USB-C plug. Users can enjoy a wireless fast charging experience with a power of up to 15W with a USB PD fast charger.

The AirPower that matched the mobile phone at that time has not been officially commercialized due to efficiency and cost.

On March 29 last year, Apple officially announced the abandonment of AirPower wireless chargers. On the same day, Dan Riccio, Apple’s senior vice president of hardware engineering, issued a statement saying, “After hard work, Apple finally concluded that AirPower could not meet our high standards, so we cancelled the project.” He also said “We still believe that the future is wireless, and we are committed to pushing the wireless experience forward.” Since then,Apple has indeed not given up on wireless charging, and has played more with wireless charging. It has not only launched a variety of wireless charging products, but has become a paid accessory product for Apple’s new machine.

To achieve 15W wireless charging power, you must use original MagSafe accessories. , Apple’s official website is priced at 329 yuan. It also launched a paid accessory magnetic protective case for wireless charging equipment. If you don’t want to affect the magnetic function while wearing the case, the original magnetic protective case prepared by Apple is priced at 399 yuan, which is also not cheap.

Apple’s move can be described as nakedly raising the added value of wireless charging.

The prosperity of the world is for profit; the hustle and bustle of the world is for profit. As an important indicator of the development of global mobile phone technology, wireless charging has been influenced by Apple, the top-notch “opinion leader”, and the broad future and imagination of wireless charging have become more and more clear.

The analysis pointed out that the wireless charging solution technology in the current market has already been very mature, but some manufacturers have not yet achieved higher wireless charging efficiency due to safety, stability, and comprehensive mobile phone conditions. With the cancellation of the included power adapter charging head and the release of MagSafe wireless charging function, Apple will further accelerate the substantial penetration of mobile phone wireless charging applications.

While Apple has been stagnating in the charging field, domestic smartphone giants such as Huawei and Xiaomi have made concerted efforts. The reporter combed the achievements of the three domestic mobile phone representatives of Huawei, Xiaomi and OPPO in wireless charging in the past three years. Huawei has launched mobile phones that support 15W, 27W, and 40W wireless charging, Xiaomi has launched mobile phones that support 10W, 30W, and 50W wireless charging, and OPPO has launched mobile phones that support 40W and 65W wireless charging this year. Driven by the mobile phone market, the application scenarios of wireless charging will be broader. Consumer electronics and automotive fields can be used flexibly, and wearable devices can maximize their advantages.

The wireless charging industry mainly involves the transmitting end and the receiving end. The receiving end is divided into five links: scheme design, power chip, magnetic material, transmission coil and module manufacturing, and it drives the development of sub-industries such as wireless charging automation equipment. Domestic companies mainly occupies the magnetic material and module manufacturing links. Among them, magnetic materials account for 21% of the entire wireless charging cost and more than 50% of the material cost. The module manufacturing link accounts for no more than 10% of the industrial chain cost. Companies such as Sunlord Electronics, Hengdian Tomag, Luxshare Precision, and Tanaka Seiki are all important puzzles in the upstream of the wireless charging industry chain.

These companies have also had cooperation or talks with Apple and its suppliers. It is reported that in terms of wireless charging, Hengdian Tomag, Tiantong Co., Ltd., Helitai and other companies mainly involve magnetic materials, Sunlord Electronics, Dongshan Precision have layout transmission coils, Luxshare Precision, Speedup are related to modules, and Tanaka Seiki Mainly produces winding machines. Earlier, the reporter learned through the industry chain that Apple placed an order of 180 million pieces of wireless charging receiver magnets from suppliers at one time.

A global mobile phone manufacturer orders this type of magnetic sheet at a time in units of 100 million. Technology media VentureBeat believes that through first-party and third-party products, MagSafe can stimulate new interest in wireless charging solutions for Apple users and the entire mobile industry.

According to Soochow Securities Report, it is estimated that by 2022, the wireless penetration rate of smart phones will reach 60%, and wireless charging solutions for wearable devices will become the mainstream, and the penetration rate will reach 70%. On the other hand, smart phones and wearable devices will have a trend of increasing volume in the next three years.

The quantity is rising, the wireless charging market is expected to release huge potential in the next three years
