Frequently Asked Questions

Is the dual input automatically recognized or manually switched?

Automatically recognize DC12V/24V input, no manual switching required.

What happens if the positive and negative poles are reversed when connecting the battery?

The device features built-in reverse polarity protection. If the positive and negative terminals are connected incorrectly, the circuit will automatically disconnect to prevent damage to the equipment. Simply adjust the battery clip connections (red clip to positive terminal, black clip to negative terminal), then restore power to resume normal operation.

What is the difference between labeled 6000W and full power 3000W?

Labeled 6000W is peak power, which is only used to cope with the instantaneous high-power demand during device startup (such as air conditioner, motor startup); full power 3000W is continuous power, referring to the power that the device can stably output for a long time. When driving appliances daily, 3000W should be used as a reference to avoid total power overload.

Can it be used with a car cigarette lighter socket?

Yes, it supports both battery clip and cigarette lighter connection.
