Xiaomi Magnetic Wireless Charging Technology
Today, the Small Inductance + Magnetic Suction pre-research technology of Xiaomi magnetic wireless charging was officially announced. Since the launch of Xiaomi’s first wireless charging phone in 2018, Xiaomi has been committed to promoting the development of wireless charging technology.
Xiaomi announced today that it has brought you “small inductance + magnetic suction” wireless charging pre-research technology, magnetic suction wireless charging power up to 50W, loss reduced by 50%, to achieve a “revolutionary wireless charging experience”.
The technology includes two charging products – a Xiaomi ultra-thin magnetic suction wireless charging (30W) and Xiaomi active cooling magnetic suction wireless charging (50W), both products have not announced the price, and sales information is expected to be announced later.
Xiaomi active cooling magnetic suction wireless charger: both heat dissipation and magnetic suction charging, the surface temperature can be reduced by 20℃ in 1 minute, 50W power, 49 minutes to fill up the 5000 mAh battery.

Faster speed, lower heat, smaller size, better ease of use where the next direction of wireless charging technology development, the advantages of different technical routes can be both? Today, Xiaomi officially released the “small inductance + magnetic suction” wireless charging pre-research technology, which relies on several technological innovations, hit the traditional high-power wireless charging heat, large components, limited use of scenarios, and other pain points, to bring users a comprehensive innovation of wireless charging experience.
Small inductance wireless charging solution, reducing loss by more than 50%
In traditional wireless charging solutions, large inductance coils are usually used at the receiving end, and the impedance of these coils is above 250mΩ, which leads to higher coil module temperature, lowering the charging speed and affecting the user experience.
The key to small inductance wireless fast charging technology is to use small inductance coils to sense the energy at the transmitter side. Xiaomi’s small inductance charging solution uses a receiver coil with only about 1/3 of the inductance value of the traditional solution, and under the same conditions, the loss can be reduced to more than half of the traditional coil.
Support up to 50W wireless magnetic wireless charging magnetic suction wireless charging new record
Magnetic wireless charging, through the adsorption force of the magnet, the wireless charging transmitter coil and receiver coil closely together, with a novel appearance, small size, friendly interaction, 360 rotation without obstruction, etc., is another development direction of the future wireless charging technology.
However, the strong magnetic field of magnets can easily lead to coil current saturation, and the heat at both the transmitting and receiving ends of the magnetic wireless charging system is more likely to be superimposed, making it difficult to achieve both “magnetic suction” and “high power”.
Xiaomi has developed the “small inductance + magnetic suction” wireless charging solution over two years to address the problems of “coil current saturation” and “heat superposition”, which fully combines the advantages of both technologies.
It fully combines the advantages of both technologies and greatly enhances the wireless charging experience of users. Today, Xiaomi officially announced two “small inductance + magnetic suction” charging products, Xiaomi ultra-thin magnetic suction wireless charging (30W) and Xiaomi active cooling magnetic suction wireless charging (50W).
Xiaomi ultra-thin magnetic suction wireless charger
The new appearance, strong magnetic suction: small body, equipped with 17 ring array of the poly magnetic core, with a hand can be automatically aligned adsorption; support 360 magnetic suction, free to adjust the angle, horizontal and vertical screen use scenarios can play while charging without obstruction; with 800g super strong suction, can be stable adsorption of about 4 cell phone weight. Ultra-high power, speedy flash charging: power up to 30W, measured 86min full 5000mAh battery.
Intelligent regulation, safety protection: for the actual charging scene, provide over-current protection, over-voltage protection, over-temperature protection, over-charge protection, over-power protection, under-voltage protection, short-circuit protection, electrostatic protection, electromagnetic field protection, foreign body protection, and other multiple security measures, charging safety and peace of mind; tempered glass panel insulation + aluminum alloy shell efficient thermal conductivity, with intelligent power regulation, can be in the charging process according to the temperature of the phone, the whole charging is calmer.
Xiaomi active cooling magnetic wireless charging
For the hardcore gamers, Xiaomi also introduces Xiaomi Active Cooling Magnetic Suction Wireless Charger, which combines the ability of “efficient heat dissipation” and “fast second charging” into one, bringing an unprecedented charging experience.
It also has a small size, equipped with 17 ring-shaped arrays of the poly magnetic core, 3609 arbitrary adjustments, a gentle suction from the call.
With the use of semiconductor cooling solution, hardcore cooling for the phone, the surface temperature can be reduced by 20℃ in 1min. At the same time, the charging power is further increased to 50W, and the actual test is 49 minutes full of a 5000mAh battery, helping you to return to the game at a fast pace.
