4. Operating Instructions
Powering Your Device
Once connected as described in the Setup section, the onerbl AC-DC Adapter will begin supplying power to your AUTOONE Car Battery Jump Starter. This adapter is designed to charge the internal battery of the jump starter or provide continuous power if the jump starter supports direct power operation. The charging time will vary depending on the jump starter's battery capacity and current charge level.
Important Note: Rechargeable batteries have a finite lifespan, typically 1 to 3 years. If your jump starter's battery is damaged or has reached the end of its life, it may not accept a charge, and this is not an indication of a fault with the charger itself.
5. Maintenance
To ensure the longevity and optimal performance of your onerbl AC-DC Adapter, follow these maintenance guidelines:
- Cleaning: Disconnect the adapter from the power outlet and your device before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or abrasive materials.
- Storage: Store the adapter and cable in a cool, dry place away from direct sunlight and extreme temperatures. Avoid tightly coiling the cable to prevent damage.
- Handling: Do not drop, disassemble, or attempt to repair the adapter. Avoid exposing it to water or high humidity.
