Not universal.
1. AirPods2's wired and wireless charging pods are not universal, they have different designs and connections.
The wired charging bin needs to be charged through the Lightning port, while the wireless charging bin can be charged through the wireless charger of the Qi standard. 2. Although the two charging pods are similar in appearance, the internal structure and interface are different, so they cannot be used interchangeably.
Therefore, AirPods2's wired and wireless charging pods are not universal.
