⚠️ Important Usage Notes
- Modified sine wave only — NOT compatible with devices powered by built-in motors, including hair dryers, air conditioners, coffee machines, water pumps, induction cookers, refrigerators, and microwave ovens.
- Ensure the total rated power of connected devices does not exceed 300W during continuous use.
- When using the cigarette lighter plug, keep total output under 150W. For outputs between 150W–300W, use the included crocodile battery clamps directly on the vehicle battery.
- Suitable for DC 12V vehicles only — not for 24V trucks, electric vehicles, or aircraft.
- Always connect to the battery first, then switch the inverter ON. Do not leave the inverter switched ON before starting the car.
- Keep the inverter dry, away from moisture, and operate within 0°C–40°C ambient temperature. Avoid direct sunlight or heat vents.

Frequently Asked Questions
Q: What is the difference between 4000W peak power and 300W rated power on this car power inverter?
A: The 4000W peak power refers to the maximum surge wattage the inverter can handle for a very brief moment (such as when a device first starts up). The 300W rated power is the maximum continuous wattage it can safely deliver during normal operation. Always ensure your connected devices' total rated power stays at or below 300W for safe, reliable performance.
Q: Can I use this 12V car inverter with a cigarette lighter socket?
A: Yes — the included cigarette lighter plug allows quick, tool-free connection to your car's 12V socket. However, cigarette lighter sockets typically have a current limit, so keep total power output under 150W when using this connection method. For loads between 150W and 300W, use the included crocodile battery clamps connected directly to your vehicle's battery.
Q: What devices can I run with this modified sine wave inverter?
A: This inverter works well with most standard electronics such as laptops, smartphones, tablets, LED lighting, cameras, small fans, and similar devices. Because it produces a modified sine wave (not a pure sine wave), it is not recommended for devices with built-in motors or sensitive electronics — including hair dryers, air conditioners, refrigerators, microwave ovens, coffee machines, water pumps, or induction cookers.
Q: Is this car power inverter compatible with 24V truck batteries?
A: No. This inverter is designed exclusively for 12V DC input (cars and standard passenger vehicles). It is not suitable for 24V trucks, 48V/60V electric vehicles, or use on aircraft. Using it with an incompatible voltage source may damage the unit or connected devices.
