Rated Output: 1000W Input Voltage: DC12V (11-15V) Output Voltage: 100V ± 5V Output Frequency: 60Hz Distortion Rate: <3% Efficiency: >88% Voltmeter: Input voltage, output voltage Low Battery Alarm: DC10V ± 0.5V Low Battery Shutdown: DC 9V ± 0.5V High Battery Shutdown: DC 15.5V Operating Temperature: 0-45℃, Over-Temperature Protection >75℃ Product Weight: 1.6kg Product Size: 280mm * 112mm * 65mm No-Load Current: 0.8A/1000W, 1.6A/2000W, 2.4A/3000W, 4000W Protection Functions: Includes protection functions such as low input voltage alarm, low voltage cutoff, over-temperature cutoff, overload cutoff, short circuit cutoff, input overvoltage protection, and input reverse connection protection. A cooling fan is also installed inside the unit to prevent overheating of equipment during use. (Temperature-controlled fan, starts rotating at 45℃ or higher) ※Accessories: 2x 7 Sq battery connection clips, 1x cigarette lighter socket, Japanese instruction manual ※Usable with most electrical appliances This product outputs a "pure sine wave" which is the same waveform as household power. Many inverters use "square waves" or "modified sine waves" which are square waves modified to resemble a pure sine wave, and due to the nature of the waveform, the electrical appliances that can be used are limited. "Pure sine waves" have the same waveform as household power, so most electrical appliances can be used within the capacity. ※If the battery capacity is insufficient, the inverter voltage will drop rapidly, a buzzer will sound, and it will indicate that the battery power is insufficient. In this case, you need to charge the battery or select a battery with a larger capacity. Please use the cigarette lighter socket after confirming that the rated output of the equipment you are using is within 150W. Notes: The fuse in the car's cigarette lighter socket may blow at 150W or more. (Varies depending on the vehicle model) ※Caution: ●Even if the product is new, there may be scratches, dents, loose screws, and dirt due to being an imported product. Please refrain from bidding if you are overly concerned. ●We will only accept returns and exchanges for "unused" items, so please be aware of this.
