Frequently Asked Questions
Can the 3 AC sockets drive high-power devices at the same time?
Yes, but it is necessary to ensure that the total power of the 3 devices does not exceed 2000W (continuous power). For example, it can drive 1 1000W electric oven + 1 500W microwave + 1 400W printer at the same time (total power 1900W), avoiding total power overload to trigger the protection mechanism.
Does the UPS function require additional mains connection?
Yes. The inverter needs to be connected to a home/office socket via the included mains cable, and the device will automatically detect the mains status; when the mains power is interrupted, it will switch to battery power immediately.
What devices can it power?
Suitable for fans, lights, TVs, laptops, and small electric tools.
Can this inverter power a laptop?
If the laptop power is within 150W and the input is AC220V, it can supply power normally.
