FAQ:
Can 4 USB ports charge 4 mobile phones at the same time?

 Yes, the total current of 6.8A can support simultaneous fast charging of multiple devices, and the charging efficiency is guaranteed.

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.

Can it drive a 3P air conditioner and an electric oven at the same time?

Total power needs to be calculated: the rated power of a 3P air conditioner is about 2200W-2500W, and the electric oven is about 1500W-2000W. The total power is 3700W-4500W, which exceeds the 3000W continuous power, so simultaneous use is not recommended; if used alone, the 6000W peak can meet the startup needs of both, and the battery capacity must be ≥200Ah (12V) when used alone.

Is the dual input automatically recognized or manually switched?

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

Which regional plugs are supported by the universal socket?

The universal socket is compatible with most national plug specifications, such as GB, US, EU, etc. (some require adapters), and can meet the use of devices in different regions.
