3. Setup

- Connect to Power Outlet: Plug the AC prongs of the adapter into a standard wall power outlet (100-240VAC).
- Power On: Once connected, your device should begin charging or receive power. Refer to your device's manual for specific charging indicators.
Safety Precautions:

4. Operating Instructions
The UpBright 12V AC/DC Adapter functions as a power supply and charger for compatible devices. Once properly connected as described in the Setup section, the adapter will automatically provide power or initiate charging.
- Charging: When connected to a compatible device like the Anker Soundcore Rave Party 2 speaker, the adapter will supply the necessary power to charge its internal battery. The charging status (e.g., LED indicators) will typically be displayed on the device itself.
- Direct Power: If the device can operate directly from AC power without a battery, the adapter will provide continuous power.
Always ensure the adapter is securely connected to both the device and the power outlet during operation.
5. Maintenance
5.1 Cleaning
- Disconnect the adapter from the power outlet and the device before cleaning.
- Wipe the adapter with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
5.2 Storage
- Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid tightly coiling the cable to prevent damage.

6. Troubleshooting
- Device Not Charging/Powering On:
- Ensure the adapter is securely plugged into both the wall outlet and the device.
- Check if the wall outlet is functional by plugging in another device.
- Verify that the adapter's specifications (voltage, current) match your device's requirements.
- Note on Rechargeable Batteries: Rechargeable batteries have a limited lifespan, typically 1 to 3 years. If your device's battery is old or faulty, it may not accept a charge, which is a device issue, not an adapter malfunction.
- Adapter Overheating:
- A slight warmth is normal during operation. If the adapter becomes excessively hot, disconnect it immediately.
- Ensure adequate ventilation around the adapter and avoid covering it.
- Confirm the adapter is not overloaded by connecting it to an incompatible device.
