Step 3: Installing the cotton swab into the top cover.
- Connect Power: Place the top cover back onto the humidifier body. Connect the USB-C cable to the humidifier's USB-C port and plug the other end into a compatible USB power source (e.g., computer, power bank, wall adapter).

Step 4: Connecting the USB-C power cable.
