Applicable Scope:
Momcozy White Noise WN03
Solution:
1. Use a standard 5 V / 1 A adapter and a USB-to-USB-C cable. A full charge normally takes about 2.5 hours, although charging time can vary with the power source and battery condition.
2. Inspect the cable, plug, and USB-C port for looseness, bent parts, moisture, lint, or damage. Remove only loose surface dust with a dry soft brush; do not insert metal tools or liquid into the port.
3. Test one known working cable, adapter, and outlet. Leave the unit connected for 30 minutes before checking whether it can turn on.
4. If charging starts only when the connector is held at an angle, the port feels loose, charging repeatedly starts and stops, or the cable/port becomes unusually hot, stop using that charging setup.
