How to Charge the Sky Ace?
Charging the Transmitter
Double click the MFB on the Transmitter to check its battery level. It’s best to initiate charging when the Relay is at 25% battery level or below.
Charging the Earbuds
If you hear the voice prompt “Battery Low” from the earbuds, that means it’s time to charge them. Place the earbuds back into the charging case and close the case.
The case will charge the earbuds. If you need to charge the case, please connect the provided Type C cable to a DC5V/500mA-2A power source.
