Product Care
- This product is designed for 12V car sockets. Do not use it with 24V car sockets.
- Make sure the power demand of your connected devices doesn't exceed the 150W total power output rating when used on a car cigarette port. Do not overload this inverter or plug any cigarette adapter or extra extension cable into the 12V input.
- This product is a modified sine wave inverter. Some sensitive devices like professional audio equipment and medical devices require a pure sine wave inverter. Refer to your device's manual or contact the manufacturer for details.
- It's normal for this inverter to generate heat during use.
- Do not cover the inverter or block the ventilation area. Keep away from liquids and extreme heat.
- Please make sure you have plugged in the cigarette lighter, whether its size is okay, and make sure the output voltage of the car cigarette lighter is 12V.
FAQs and Solutions
- How does the fan of the inverter work?
When you turn on the switch, the fan will be half-started, which means that the fan speed is only half. When the temperature is about 42°C, the fan is fully open and fully rotated. So when you don't use the inverter, you can turn off the AC switch. - Does this Inverter automatically shut down?
Yes, the Inverter has the protection of low-voltage (10.0±0.5V). And it's recommended to pull out the Inverter when not using. - Can I use the cigarette lighter for any electric appliances?
No, when the electric appliance is powered less than 150W, please use the cigarette lighter; when more than 150W, it should be used out of the car with the Alligator Clip (please purchase separately). - Can I use the USB port if not switching on?
Yes, you can. The switch only controls the AC outlets. - How can I know the voltage of my car?
Please check around the cigarette lighter or contact the car manufacturer to know. - Why is the measured inverter output too low by a voltmeter?
Because this inverter is a Modified sine wave, its output requires a "true RMS" multimeter to test, which can get an accurate measurement. An ordinary multimeter can't measure the true voltage.
