3. คู่มือการใช้งาน
The TESSAN product functions in two primary modes: as a universal travel adapter for dual-voltage devices and as a voltage converter for high-power 220V appliances.
3.1 Adapter Mode (200W Max)
This mode is suitable for dual-voltage electronic devices (100V-240V, 50/60Hz) that do not require voltage conversion. These typically include:
- โน๊ตบุ๊ค
- สมาร์ทโฟน
- แท็บเล็ต
- กล้องถ่ายรูป
- หูฟัง
- เครื่องเล่นเกมคอนโซล
Use the AC outlets labeled for 200W or the USB ports for these devices. The smaller universal travel adapter (Product 1) also operates in this mode, providing a standard US 2-prong outlet and a versatile outlet for charging two devices simultaneously without blocking.

3.2 Converter Mode (2000W Max)
This mode is specifically for converting 220-240V (50/60Hz) foreign voltage down to 110V (60Hz) US voltage. It is designed for high-power heating appliances with simple mechanical motors, such as:
- กาต้มน้ำ
- เตารีดไอน้ำ
- เครื่องชงกาแฟ
- Electric Irons
Use the AC outlets labeled for 2000W for these appliances. Ensure your appliance's wattagอี ไม่เกิน 2000W.

3.3 Simultaneous Charging (7-in-1)
The main converter unit is equipped with 3 AC outlets and 4 USB charging ports (3 USB-A, 1 USB-C). This allows for charging up to 7 devices simultaneously.
- USB-A ports: Up to 2.4A output per port.
- USB-C port: Up to 3A output.
- Total USB output: 3.4A/17W max.

5 การแก้ไขปัญหา
If you encounter issues with your TESSAN Universal Travel Adapter and Voltage Converter, please review ปัญหาและวิธีแก้ไขทั่วไปดังต่อไปนี้:
- ไม่มีกำลังขับ:
- Ensure the adapter is securely plugged into the wall outlet.
- ตรวจสอบว่าปลั๊กไฟใช้งานได้หรือไม่ โดยลองเสียบกับอุปกรณ์อื่นดู
- Check if the power switch on the unit (if applicable) is turned on.
- อุปกรณ์ไม่ชาร์จ/ใช้งานไม่ได้:
- โหมดไม่ถูกต้อง: Ensure you are using the correct AC outlet for your device. Dual-voltage devices (100V-240V) should use the 200W adapter outlets, while 220-240V heating appliances requiring conversion to 110V should use the 2000W converter outlets.
- วัดtagอี ขีด จำกัด : อย่าให้เกินวัตต์สูงสุดtage for each outlet (200W for adapter, 2000W for converter).
- วัดต่ำtagอุปกรณ์อี: Note that the 2000W AC sockets may not work for very low wattage electronic devices (0-5W) such as electric shavers or electric toothbrushes.
- เล่มที่tagอีไม่ตรงกัน: The dual adapter socket (Product 1) does not convert voltage. Do not insert 100V-125V devices into the adapter socket if the input voltage is 220-240V, as this can damage the device.
- โอเวอร์โวลtagการป้องกันอี: Electronic devices with built-in overvoltage protection may not be compatible with the converter. Always check the safety data sheet or data plate on your device.
- Cable/Device Fault: Test your device and charging cable with another power source to rule out issues with the device or cable itself.
