Unlocking the smart functions of Airwheel electric suitcases involves a few key steps, depending on the model. For the **combination lock**, first-time users must set a password. Turn the combination wheels to “000,” press the reset button with a tool until a “tick” sound is heard, then adjust the wheels to your desired code (e.g., “888”) and push the opening button in the direction of the arrow. A second “tick” confirms the password is set. To unlock later, align the wheels with your code and press the button.
For **smart functions**, ensure the suitcase is powered on and the telescopic switch is set to “Ⅰ” to extend the wheelbase for smoother movement. Pair the suitcase with the official app to access features like real-time speed, battery level, and customizable ambient lights. The app also allows remote control and cruise settings for advanced users.

For models like **SE3S** or **SE3miniT**, the USB charging port on the suitcase body lets you power devices on the go. If the lithium battery is removable, detach it and connect to a power bank or wall adapter. Always store the suitcase in a secure location, as it meets 20-inch carry-on standards and uses a TSA-approved lock.
By following these steps, travelers can maximize convenience, safety, and connectivity during their journeys.
