1. Introduction
The Walfront Universal Voltage Converter is designed to facilitate the use of electrical appliances across different voltage standards worldwide. This device allows for both step-up conversion (from 110V to 220V) and step-down conversion (from 220V to 110V), with a maximum output power of 120W. Its compact and lightweight design makes it suitable for international travel.
2. Safety Information
- Maximum Power: Do not exceed the maximum output power of 120W. Overloading the converter can cause damage to the unit and connected appliances, and may pose a fire hazard.
- Indoor Use Only: This converter is intended for indoor use in dry environments. Do not expose to water, moisture, or extreme temperatures.
- Ventilation: Ensure adequate ventilation around the converter during operation to prevent overheating.

4. Setup
Before connecting any appliance, it is crucial to select the correct voltage setting on the converter. Incorrect voltage selection can damage your appliance or the converter.
- Locate the Voltage Selection Switch: Turn the converter upside down to locate the input voltage selection switch. This switch is typically a small slider.
- Select Input Voltage:
- If the wall outlet provides AC110V (e.g., in North America), slide the switch to the AC110V position. The converter will then output AC220V.
- If the wall outlet provides AC220V (e.g., in Europe, Asia), slide the switch to the AC220V position. The converter will then output AC110V.
- Verify Appliance Wattage: Ensure that the appliance you intend to use does not exceed the converter's maximum output power of 120W.

5. Operating Instructions
- Confirm Voltage Selection: Double-check that the input voltage selection switch on the bottom of the converter is set correctly for the wall outlet's voltage.
- Plug into Wall Outlet: Insert the converter's plug into the appropriate wall outlet.
- Connect Appliance: Plug your appliance's power cord into the universal AC output socket on the front of the converter.
- Power On Appliance: Turn on your appliance.
- Disconnect: When finished, turn off your appliance, unplug it from the converter, and then unplug the converter from the wall outlet.
Important Note: This converter is designed for low-power electronic devices such as chargers, small travel appliances, and certain personal care items. It is not suitable for high-power appliances like hair dryers, irons, or heating elements that typically exceed 120W.
6. Maintenance
- Cleaning: Use a dry, soft cloth to clean the exterior of the converter. Do not use liquid cleaners or solvents.
- Storage: Store the converter in a cool, dry place away from direct sunlight and moisture when not in use.
- Avoid Drops: Protect the unit from physical shocks and drops.
