Wireless Charging
Align the bottom center of the charging case with the center of the
wireless charger.
NOTE: The wireless charger is not provided. The wireless charging
function may not work in some wireless chargers. Wireless charging
feature charges at a slower rate due to less power being transmitted
to the charging case.
If you do wireless charging, the UVnano LED sterilizes the earbuds for
5 minutes before charging.
