How does the UPS function of this inverter work?
When the external power supply is normal, the inverter powers the device while charging the battery; when the external power supply is interrupted, it automatically switches to battery power to ensure uninterrupted operation of the device.
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.
Can this inverter run a refrigerator or power tools?
Recommended load ≤80% of rated power. For inductive loads, use a pure sine wave model.
How many devices can it power at the same time?
Dual universal sockets + two USB ports can power multiple devices (such as two home appliances + two mobile phones) at the same time, as long as the total power does not exceed 600W.
Can this inverter support both 12V and 24V inputs
Yes, it can work with different voltage systems via selectable input terminals.
