Is the long-distance wireless charger compatible with Magsafe?

You may easily conclude that this is beyond doubt, as Apple has stated that all iPhone models after iPhone 8 are compatible with Qi. However, if you search online for compatibility between iPhone 12 and Qi certified chargers, you will be surprised; Many people have reported that their Qi chargers cannot charge the iPhone 12 series. The introduction of Magsafe has led to this situation.

Metal Foreign Object Safety (FOD)

At present, the frequency of energy transmission in high-power wireless charging solutions is generally in the range of tens of KHz to hundreds of KHz. This frequency range has eddy current heating effects on common metals. It is more vivid to use a product to explain it, which is an "induction cooker". However, wireless charging technology pursues efficient energy transfer rather than eddy current heating. If there are metal foreign objects present in the wireless charging area, they will be continuously heated due to eddy current effects, which poses a potential risk of damaging equipment and even causing fires. Therefore, wireless charging solutions should avoid eddy current effects in industry applications, in order to improve transmission efficiency and safety.

Coupling coefficient in wireless charging (power supply)

Based on the distance between the transmitting coil and the receiving coil, only a small portion of the magnetic flux generated by the transmitting coil will penetrate the receiving coil and facilitate power transmission. The more magnetic flux reaches the receiver, the better the coil coupling effect. The tightness of coupling is represented by the "k value", which is the "coupling coefficient".
