3. Product Overview
The onerbl AC-DC Adapter is a power supply unit designed for charging and operating compatible devices. It converts alternating current (AC) from a wall outlet to direct current (DC) required by your device. The adapter features built-in short circuit protection for enhanced safety.

The image displays the two main components of the onerbl AC-DC Adapter: a compact black wall adapter featuring a standard US two-prong plug and a USB-A output port, and a coiled black USB-A to Micro-USB cable used for connecting the adapter to compatible devices.
4. Setup
- Unpack the onerbl AC-DC Adapter and the included USB-A to Micro-USB cable.
- Connect the USB-A end of the cable into the USB-A port on the AC-DC wall adapter.
- Plug the AC-DC wall adapter into a standard electrical wall outlet (AC 100-240V).
- Connect the Micro-USB end of the cable into the charging port of your compatible device, such as the ACEZUK M03 Jump Starter.
5. Operating Instructions
Once properly connected, the adapter will begin to supply power to or charge your device. Refer to your device's instruction manual for specific charging indicators or operational details. The adapter is designed for continuous use during charging or operation of your device.
6. Maintenance
- To clean the adapter, disconnect it from the power source and wipe it with a dry, soft cloth. Do not use liquid cleaners.
- Store the adapter and cable in a cool, dry place when not in use.
- Avoid tightly coiling the cable to prevent damage to the internal wires.
7. Troubleshooting
- Device Not Charging: Ensure all connections are secure and the wall outlet is functional. Verify that your device is compatible with a 5V DC input.
- Battery Condition: Rechargeable batteries have a finite lifespan, typically 1 to 3 years. If your device's battery is damaged or has reached the end of its life, it may not accept a charge, even with a functional adapter. This is a characteristic of the battery, not a defect of the charger.
- Adapter Overheating: If the adapter feels excessively hot, disconnect it immediately and allow it to cool. Ensure it is used in a well-ventilated area and not covered.
