4. Setup Instructions
- Unpack the Charger: Carefully remove the WEKOME WP-U128 charger from its packaging. If purchased with cables, ensure they are also removed.
- Select Appropriate Cable: Use a USB-C to USB-C cable for devices with a USB-C port, or a USB-C to Lightning cable for Apple iPhone/iPad devices. Ensure the cable supports the desired charging speed (e.g., 20W for iPhone fast charging, 100W for laptops).
- Plug into Power Outlet: Extend the foldable plug and insert the charger firmly into a compatible wall power outlet (110-240V~50/60Hz).
- Connect Device: Plug one end of your charging cable into one of the USB-C ports on the charger and the other end into your device's charging port.
- Verify Charging: Your device should indicate that it is charging. For fast charging, ensure your device and cable support the fast charging protocols (e.g., PD, QC).

5. Operating Instructions
Single Device Charging:
When charging a single device, the charger can deliver up to 40W of power, depending on your device's requirements and the cable used. For optimal fast charging, ensure your device supports Power Delivery (PD) and use a high-quality USB-C cable.
PD40W fast charging for a single device.
Dual Device Charging:
When two devices are connected simultaneously, the charger intelligently distributes power, typically providing 20W to each port. This allows for efficient fast charging of two devices at once.
Dual-port output for charging two devices simultaneously.
Understanding Charging Speeds:
The actual charging speed may vary based on several factors:
- Device Compatibility: Your device must support fast charging protocols (e.g., PD, QC) to achieve maximum speeds.
- Cable Quality: Use certified cables that can handle high power delivery.
- Battery Level: Charging speeds are typically fastest when the battery is low and slow down as it approaches full capacity.
- Environmental Factors: Extreme temperatures can affect charging performance.
6. Safety Information
The WEKOME WP-U128 charger is designed with multiple protection features to ensure safe operation. Please observe the following safety guidelines:
- Do not expose the charger to water, moisture, or extreme temperatures.
- Avoid dropping, disassembling, or attempting to repair the charger yourself.
- Use only compatible and certified charging cables.
- Keep out of reach of children.
- Unplug the charger from the wall outlet when not in use or during electrical storms.
- Ensure proper ventilation around the charger during use.
Built-in Protections:
- Over-input Protection: Prevents damage from excessive input current.
- Over-voltage Protection: Safeguards against voltage surges.
- Short Circuit Protection: Automatically cuts power in case of a short circuit.
- Over-output Protection: Protects devices from excessive output current.
- Over-power Protection: Prevents damage from exceeding the charger's maximum power output.
- Overheating Protection: Monitors temperature and reduces power or shuts down if it gets too hot.

7. Maintenance
- Cleaning: Disconnect the charger from the power outlet and all devices before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or aerosols.
- Storage: Store the charger in a cool, dry place away from direct sunlight and extreme temperatures. The foldable plug design makes it easy to store and transport.
- Cable Care: Avoid bending or twisting cables excessively, as this can damage the internal wires.
8. Troubleshooting
- Device not charging:
- Ensure the charger is securely plugged into a live wall outlet.
- Check if the charging cable is properly connected to both the charger and your device.
- Try using a different charging cable to rule out a faulty cable.
- Test the charger with a different device to confirm the charger is functioning.
- Slow charging:
- Verify that your device supports fast charging protocols and that the cable used is rated for fast charging.
- If charging two devices simultaneously, the power is split (20W per port), which may result in slower charging compared to single-port 40W charging.
- Close any power-intensive applications running on your device.
- Ensure the ambient temperature is not excessively high, as this can trigger thermal protection and reduce charging speed.
- Charger feels warm:
- It is normal for the charger to feel warm during operation, especially during fast charging. The GaN technology helps manage heat efficiently.
- If the charger becomes excessively hot to touch, disconnect it immediately and allow it to cool down. Ensure it is used in a well-ventilated area.
9. User Tips
- Optimal Cable Pairing: To achieve the advertised fast charging speeds, always use high-quality USB-C cables that are compatible with your device's fast charging standards (e.g., a 20W USB-C to Lightning cable for iPhones, or a 100W USB-C to USB-C cable for laptops).
- Portability: The foldable plug design makes this charger ideal for travel. Remember to fold the pins when packing to prevent damage and save space.
- Check Device Compatibility: Before expecting fast charging, confirm that your device supports Power Delivery (PD) or Qualcomm Quick Charge (QC) protocols.
