2. Safety Instructions and Precautions
To ensure safe operation and prevent damage to your devices or the converter, please read and follow these instructions carefully:
- Check Device Wattage: Before using the converter mode, always verify the wattage of your appliance. This converter supports devices up to 800W.
- Incompatible Devices (Converter Mode): This converter is not suitable for devices with power consumption of 25W or less, such as electric toothbrushes, electric shavers, hair straighteners, curling irons, or electric drills. Using these devices in converter mode may cause damage. Always check your device's safety data sheet or nameplate.
- CE Certification: The product is CE certified, ensuring it meets European safety standards.
- Built-in Fuses: Equipped with a main fuse and a spare fuse for protection against overloads. The device will automatically power off during abnormal use to protect connected electronics.
- Overload and Short Circuit Protection: Advanced design features prevent damage from overloads and short circuits.
- Proper Mode Selection: Ensure you select the correct mode (Adapter or Converter) based on your appliance and destination voltage. Incorrect mode selection can damage your device.

4. Setup and Usage Instructions
4.1 Selecting the Correct Plug Type
- Identify the required plug type for your destination (US, EU, UK, AU, or Type C).
- Locate the corresponding slider on the side of the adapter.
- Slide the button to extend the correct prongs. Only one set of prongs can be extended at a time.
4.2 Choosing Between Adapter and Converter Mode
The device has a switch to select between 'Adapter' and 'Converter' modes. This is crucial for safe operation:
- Adapter Mode (100V-250V): Use this mode for dual-voltage appliances (e.g., most laptops, phone chargers, cameras) that can handle a wide range of input voltages. In this mode, the device acts as a pass-through adapter, changing only the plug shape, not the voltage.
- Converter Mode (220V-250V to 100V-120V): Use this mode for single-voltage Japanese appliances (e.g., hair dryers, small heating appliances) that are rated for 100V-120V and have a wattage between 25W and 800W. This mode steps down the higher foreign voltage to a safe level for your Japanese appliance.
WARNING: Never use Converter Mode for devices rated 25W or less, or for sensitive electronics like electric toothbrushes, shavers, hair straighteners, or curling irons, as this may damage them. Always confirm your appliance's voltage and wattage requirements.
4.3 Using the USB Charging Ports
The device includes 2 USB-A and 2 USB-C ports for charging. These ports operate independently of the adapter/converter mode and provide a total output of 17W.
- Connect your USB charging cables to the appropriate USB-A or USB-C ports.
- Plug the adapter into a wall outlet.
- Your devices (smartphones, tablets, etc.) will begin charging.

- Device Not Charging/Working:
- Confirm you have selected the appropriate mode (Adapter or Converter) for your device and destination voltage.
- Check your device's wattage. If using Converter Mode, ensure it is between 25W and 800W.
- For USB charging, ensure your USB cables are functional and correctly connected.
- Unusual Noise or Smell: Immediately unplug the device from the wall outlet and disconnect all appliances. Do not attempt to use it again. Contact customer support.
