Question: How do I charge my Laser Smart Sleeping Mask Earphone?
Answer:
Plug the USB-C cable into the charging port.
Connect the other end to a standard 5 V USB-C power source (wall charger, powerbank, or laptop).
Red light = charging.
Blue light = fully charged (turns off after ≈30 seconds).
Do not use 9 V or 12 V adapters.
Never charge while wearing or cleaning the mask.
