Apple announced a case of wireless charging of AirPod about iPhone X announcement event about a year ago, but since Apple has not released yet, I guess about the function. According to a new report AirPods 'wireless charging case is shipping to support Apple' s not yet released AirPower pads, as well as Qi – compliant charging pads.
Talking supply chain source Chongdiantou I spilled Apple's design decision beans. Supply chain information sources are somewhat dubious because their knowledge of Apple's master plan is limited.

In other words, it makes sense to support a wide range of Qi compatible charger pads. Apple's current iPhone, unlike the Apple Watch Series 3, operates with many Qi-rated chargers, and its attached charger has its limitations.
Hopefully, AirPods' wireless charging case along with AirPods will hopefully be well by this fall iPhone lineup will be released. Based on the launch of Apple's previous iPhone, it will be some time in late September.
