1. Introduction
This manual provides essential information for the safe and effective use of your Kircuit 20V 1.5A AC/DC Adapter Charger. This power supply is designed to convert alternating current (AC) from a wall outlet into direct current (DC) required by compatible devices, specifically Roborock Q Revo, QX0PEA, EWFD11LRR, and EWFD12LRR robot vacuum cleaners and their docking stations.
The adapter features a robust design with built-in dynamic IC, charger IC, and power fuse for efficient and protected charging. Please read this manual thoroughly before use and retain it for future reference.

2. Safety Information
To prevent injury or damage to the product, observe the following safety precautions:
- Indoor Use Only: This adapter is designed for indoor use in dry locations. Do not expose it to rain, moisture, or extreme temperatures.
- Avoid Liquid Contact: Do not immerse the adapter in water or any other liquid. If the adapter comes into contact with liquid, immediately unplug it from the power outlet.
- Proper Ventilation: Ensure adequate ventilation around the adapter during operation. Do not cover it or place it in an enclosed space where heat cannot dissipate.
- Correct Voltage: Only connect the adapter to power outlets providing the specified input voltage (100-240V AC).
- Cable Integrity: Regularly inspect the power cords for any signs of damage. Do not use the adapter if the cords are frayed, cut, or otherwise damaged.
- Disconnect Safely: Always grasp the plug, not the cable, when disconnecting the adapter from the wall outlet or the device.
- Do Not Disassemble: Do not attempt to open or repair the adapter. Doing so will void the warranty and may pose a safety risk. Refer all servicing to qualified personnel.
- Compatibility: Use this adapter only with devices specified as compatible. Using it with incompatible devices may cause damage to the device or the adapter.
- Children and Pets: Keep the adapter and its cables out of reach of children and pets to prevent accidental injury or damage.
3. Setup
Follow these steps to set up your Kircuit AC/DC Adapter Charger:
- Unpack: Carefully remove the adapter and all cables from the packaging.
- Connect AC Power Cord: Take the detachable AC power cord (the one with the two-prong wall plug) and connect its C7 connector end firmly into the AC input port on the main adapter unit.
- Connect DC Output Cable: Plug the barrel connector of the adapter's DC output cable into the designated power input port on your compatible device (e.g., Roborock Q Revo robot vacuum) or its docking station. Ensure a secure connection.
- Plug into Wall Outlet: Insert the two-prong wall plug of the AC power cord into a standard 100-240V AC electrical wall outlet.
Once connected, the adapter is ready to supply power to your device or initiate charging if the device is connected to its docking station.

4. Operating
The Kircuit AC/DC Adapter Charger operates automatically once properly connected to a power source and a compatible device.
- Power Indicator: The adapter unit may feature a small LED indicator light (often blue) that illuminates when the adapter is receiving power and functioning correctly. Refer to Image 4.1 for an example of the indicator light.
- Charging Process: When connected to a compatible device or its docking station, the adapter will provide the necessary 20V DC power to operate the device or charge its internal battery. The charging status (e.g., battery level, charging complete) is typically indicated by the device itself, not the adapter.
- Continuous Power: The adapter is designed for continuous operation within its specified limits. It provides a stable power supply to ensure reliable performance of your robot vacuum cleaner.

5. Maintenance
Proper maintenance ensures the longevity and safe operation of your adapter:
- Cleaning: Disconnect the adapter from the power outlet and the device before cleaning. Use a soft, dry cloth to wipe the exterior of the adapter. Do not use liquid cleaners, solvents, or abrasive materials.
- Storage: When not in use for extended periods, unplug the adapter and store it in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid tightly coiling the cables to prevent damage.
- Cable Management: Avoid placing heavy objects on the cables or bending them sharply. This can damage the internal wires and compromise safety.
- Inspection: Periodically inspect the adapter casing and cables for any signs of physical damage, such as cracks, cuts, or discoloration. If damage is observed, discontinue use and replace the adapter.
