At present, wireless charging is actively promoted in China, and Xiaomi, OPPO and Huawei are more powerful. At present, Xiaomi has reached 50W wireless charging, with OPPO at the earliest 65W and Huawei at 40W. Recently, Huawei applied for a patent for long-distance wireless charging. This way, you don't have to worry about charging your mobile phone, and you don't have to carry a charger with you.
Laser wireless charging technology
From the concept of Huawei, laser wireless charging supports mobile phones, drones and so on. , the distance can reach the mid-range level.
Of course, considering the danger of laser, Huawei's laser transmitter has also made a safety function, which is to automatically turn off the charging when detecting human eyes to protect it.
The realization of laser charging also requires the terminal to be equipped with corresponding micro-sensors.
Huawei confirmed the authenticity of developing the above technology, but pointed out that the charging power and charging time have not been finalized. Huawei personnel expect that it will take at least two to three years to see the laser wireless charging technology put into commercial use.
Long-distance wireless charging is not the first time.
In fact, some time ago, OPPO launched a concept video, and I still have an impression. On April 1 day of this year, OPPO officially announced the new Ace infinity machine, equipped with the world's first FreeVOOC charging technology, which can achieve a stable charging power of 5- 10W within the range of10m. Where the mobile phone is, the power will follow.
Space charging, even long-distance wireless charging, can be realized without technical obstacles. However, when commercialized, there are requirements of laws and regulations, equipment safety and personal safety, and cost.
