Introduction
This manual provides essential instructions for the safe and effective use of your TESSAN Universal Travel Adapter and Voltage Converter. This device is designed to provide power solutions for your electronic devices when traveling internationally, offering both universal plug compatibility and voltage conversion capabilities.
The product combines two main functionalities:
- Universal Travel Adapter: A compact adapter with interchangeable plugs (Type C, G, A, I) suitable for use in over 150 countries. It features a universal AC outlet compatible with various plug types (B, C, G, A, E/F, I, L, J, N, D) and additional AC outlets.
- Voltage Converter: A separate unit that converts 220-240V AC input to 110V AC output for high-power heating appliances (up to 2000W) and a 200W adapter area for lower-power electronic devices (100-240V input). It also includes multiple USB ports (USB-A and USB-C) for charging mobile devices.
Please read this manual thoroughly before use and retain it for future reference.
Safety Precautions
- This device is not a transformer. It converts voltage for specific purposes but does not change frequency.
- Always check the voltage requirements of your device before plugging it into the adapter or converter.
- Do not use the 2000W converter section for electronic devices with complex circuits (e.g., hair straighteners with digital displays, CPAP machines, smart toothbrushes, electric shavers) as it may damage them. This section is primarily for simple heating appliances.
- The 200W adapter section is suitable for dual-voltage devices (100-240V) like laptops, smartphones, tablets, and cameras. Do not exceed 200W.
- Do not insert 100V-125V devices into the adapter sockets when used in 220-240V regions without proper voltage conversion.
- Ensure the total wattage of all connected devices does not exceed the maximum rated output of the converter or adapter.
- Keep the device away from water, moisture, and high temperatures.
- Do not disassemble or modify the device.
- Unplug the device from the wall outlet when not in use.
Product Components
Your TESSAN Universal Travel Adapter and Voltage Converter package includes the following main components:

Selecting the Correct Plug Type:
The adapter comes with four interchangeable plug types to cover over 150 countries:
- Type C: For most of Europe (e.g., Italy, Spain, France, Germany).
- Type G: For UK, Ireland, Scotland, British territories.
- Type A: For Japan, USA, Mexico.
- Type I: For Argentina, Australia, Fiji, China.

Important: This compact adapter does NOT convert voltage. Ensure your devices are dual-voltage (100-240V) or compatible with the local voltage.
2. Using the Voltage Converter (7-in-1)
This unit provides both voltage conversion and multiple charging ports, making it suitable for a wider range of devices, including high-power heating appliances.

Voltage Conversion Functionality:
The converter has two distinct areas for AC power output:
- 2000W Converter Area: Converts 220-240V (50/60Hz) to 110V (60Hz). This section is designed for simple mechanical heating appliances such as kettles, steam irons, coffee machines, and electric irons. Do NOT use for electronic devices with complex circuits or smart features.
- 200W Adapter Area: This section does NOT convert voltage. It is suitable for dual-voltage electrical appliances (100V-240V) with a maximum power consumption of 200W, such as laptops, smartphones, tablets, cameras, headphones, and game consoles.

USB Charging Ports:
The voltage converter unit includes 4 USB charging ports:
- 1 x USB-C Port: Up to 3A output.
- 3 x USB-A Ports: Up to 2.4A each.
The total output for all USB ports is 3.4A / 17W max. These ports are suitable for charging smartphones, tablets, smartwatches, and other USB-powered devices.
Connecting to Wall Outlets:
The voltage converter comes with a DE power cable and 4 international adapters (Type C, G, I, L) to connect to various wall outlets worldwide.

Operating Instructions
- Identify Your Device Type: Determine if your device is a simple heating appliance (e.g., kettle, iron) or an electronic device (e.g., laptop, phone). Also, check its voltage requirements (100-240V dual voltage or single voltage).
- Select the Correct Unit:
- For dual-voltage electronics (100-240V) up to 200W, use the 200W Adapter Area on the voltage converter or the Compact Universal Travel Adapter.
- For simple heating appliances (e.g., kettles, irons) requiring 110V output from a 220-240V source, use the 2000W Converter Area on the voltage converter.
- Choose the Appropriate Wall Plug: Attach the correct international plug adapter to your chosen TESSAN unit based on your travel destination.
- Connect to Wall Outlet: Plug the TESSAN unit into the wall outlet.
- Connect Your Devices: Plug your devices into the appropriate AC outlets or USB ports on the TESSAN unit.
- Power On (Voltage Converter only): If using the voltage converter, ensure the power switch for the AC outlets is turned on if applicable (refer to the device's indicator light). USB ports typically operate automatically.
Always verify the power requirements of your appliances and the local voltage before connecting to prevent damage.
Maintenance
- Keep the device clean and dry. Wipe with a soft, dry cloth.
- Avoid dropping or subjecting the device to strong impacts.
- Store in a cool, dry place when not in use.
