["1. The 3000W converter is only suitable for electrical devices without motors under 2000W or electrical devices with motors under 1300W. Transformers only convert voltage, not frequency Hertz. If your device is not compatible with 50/60 Hz, the usage effect will be affected.","2. An input miniature circuit breaker (MCB) is installed. When an overcurrent or short circuit occurs, the MCB will trip. Press the reset switch after tripping to continue using. MCBs are much more sensitive to overcurrent than fuses. Unlike a fuse, a blown fuse must be replaced. Therefore, it is safer and easier to use.","3. Some electrical devices, such as heaters, power tools, coffee makers, and laser printers, require 2 to 4 times the startup power. We recommend using a 3 times efficiency factor for high wattage heaters like air conditioners and welding machines.","4. Please check before using if the 110V/230V connector on the back matches the voltage you entered. If it is inconsistent, set it to the correct position.","5. There are four outlets on the front of the device, including two 230-volt outlets and two 110-volt outlets."]
