We have two schemes for wireless charging of mobile phones, one is strong coupled inductive wireless power transmission, and the other is weakly coupled magnetic resonance wireless power transmission. The strong coupling means that you must place the mobile phone in the correct position on the wireless charging base, and there can be almost no excessive deviation. Otherwise, you cannot charge it; and weak coupling means that your mobile phone is placed on the wireless charging base. It does not need to be fixed in a particular position to be charged. You can charge it as long as it is placed on the base. This is the difference between the solid and weak coupling.
So what are the components in a wireless charger module? It is mainly composed of a brass transmitting coil and chip of control circuit. The products of our wireless charging module are certified by the QI industry. The circuit for protecting the mobile phone and the charger is integrated into the chip, which significantly improves the safety factor of the user during the charging process and prolongs the battery life of the mobile phone.
Take the iPhone as an example; the official support for 7.5W output, but most only support 5W. To achieve the maximum output power, you must have a QC3.0 charging head. Otherwise, it will still output 5W, but 5W is not as good as the current fast charging technology, but it is much faster than USB (2.5W) charging.
Under the current technology, the wireless charger compromises charging and convenience. Although it cannot achieve fast charging speed, it is a good choice in the fragmented time.
