Does not come with a data cable and is not fully universal.
Because the design of Airpods2 is different from that of a mobile phone, it cannot be charged directly using a mobile phone data cable, and a specific wireless charging box is required for charging operation. In addition, Airpods2 uses Apple's own Lightning interface to charge, rather than the USB-C interface or Micro USB interface that is more common in the market at present, so it cannot be completely common with ordinary mobile phone data cables.
If you need to charge the Airpods2, you can consider buying Apple's official wireless charging case or Lightning port data cable for charging.
