Charging the Charging
Case
Connect the USB-A to USB-C charging cable to the charging
case and plug it into a USB-A power supply or certified wall
charger. A solid orange light on the charging case indicates
that it is currently charging, while a solid green light indicates
that the case is fully charged.
*Note:
• The charging case requires approximately 2 hours to reach
full charge. It operates using the standard 5V±5A USB voltage.
We advise against using high-voltage power sources to
charge the earbuds, as this may cause damage. Additionally,
using third-party charging cables may result in longer
charging times.
• Before charging, ensure that the charging port is dry and
free of liquid residue like sweat. Use a soft, dry cloth to wipe
away any moisture or residue from the charging port.
