1. Product Overview
This manual provides instructions for the UpBright 29.4V AC/DC Adapter, designed for use with various Hover-1 electric scooters and hoverboards that utilize a 25.2V 4.0Ah Lithium-ion battery and require a 29.4V power supply with a 3-prong connector. This adapter ensures proper charging and operation of compatible devices.

2. Setup and Compatibility
Before connecting the adapter, it is crucial to verify compatibility with your device to prevent damage. This adapter is specifically designed for devices requiring a 29.4V output and featuring a 3-prong connector.
2.1 Voltage and Connector Verification
- Ensure your device requires a 29.4V input. This adapter is NOT compatible with 36V or 42V versions.
- Confirm your device's charging port is a 3-prong connector. The groove on the adapter's connector must align with the convex slot on your device's charging port.

Figure 2: Voltage Compatibility. This image illustrates the importance of matching the adapter's 29.4V output with the device's required voltage, showing a correct (green check) and incorrect (red X) voltage match.

2.2 Initial Connection
- Plug the AC power cord into a standard wall outlet (100-240VAC, 50/60Hz).
- Connect the 3-prong connector of the adapter to the charging port of your compatible Hover-1 device. Ensure a secure and proper fit.
3. Operating Instructions
Once connected, the adapter will begin charging your device's lithium-ion battery. The charging process is automatic.
3.1 Charging Process
- The adapter provides a stable 29.4V DC output for efficient charging.
- Monitor your device's charging indicator (if available) to determine the battery's charge status. This adapter does not feature an indicator light to show full charge.
- Disconnect the adapter once the device is fully charged or when not in use.
4. Maintenance
Proper care and maintenance will extend the lifespan of your UpBright AC/DC adapter.
- Keep the adapter clean and dry. Avoid exposure to moisture or extreme temperatures.
- Do not expose the adapter to direct sunlight for prolonged periods.
- Store the adapter in a cool, dry place when not in use.
- Avoid bending or crimping the cable excessively, as this can damage internal wires.
- Do not attempt to open or repair the adapter. Refer to the warranty section for service.
5. Troubleshooting
If you encounter issues with your adapter, consider the following troubleshooting steps:
- Device Not Charging:
- Verify that the adapter is securely plugged into both the wall outlet and the device.
- Confirm that the device's charging port is clean and free of debris.
- Re-check the voltage and connector compatibility (refer to Section 2.1).
- Note that rechargeable batteries have a limited lifespan (typically 1 to 3 years). An old or dead battery may not accept a charge, which is not an issue with the charger itself. A voltmeter can be used to test if the charger is outputting power.
- Adapter Overheating:
- Ensure adequate ventilation around the adapter during use.
- If overheating persists, discontinue use and contact support.
