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 reason for the inverter automatically shutting down during operation?
It is likely that the protection mechanism is triggered: 1. Load overload (total power of connected devices exceeds 1000W); 2. Abnormal input voltage (battery voltage <10.8V or >14.5V); 3. Device overtemperature (excessively high ambient temperature or cooling fan failure). It is recommended to disconnect some loads, check the battery voltage or clean the heat dissipation port before trying again.
Is it a pure sine wave or a modified sine wave? What's the difference?
This is a modified sine wave inverter, suitable for most conventional home appliances and electronic devices; pure sine wave is suitable for precision devices with extremely high power requirements. This modified sine wave is more cost-effective at 2000W, meeting the needs of most scenarios.
Which regional plugs can be used with the universal socket?
The universal socket supports most national plug specifications, such as GB, US, EU, etc. (some require adapters), and can meet the use of devices in multiple regions.
What devices can be powered by the cigarette lighter port?
The cigarette lighter port can be used for car air pumps, car refrigerators, car vacuum cleaners and other conventional cigarette lighter powered devices, as long as the power does not exceed 300W.
