FAQ:
Is the cooling fan noisy during operation?

The noise is low (≤45 decibels, equivalent to normal conversation volume). The fan uses a silent motor and automatically adjusts the speed according to the device temperature (low-speed operation when temperature <40℃, high-speed operation when >60℃), balancing heat dissipation and noise.

Is it normal for the inverter to heat up when working?

It is normal for it to generate some heat when working. If the temperature is too high (e.g., hot to the touch), please stop using it and check if the load is overloaded.

Can this inverter run a refrigerator or power tools?

Recommended load ≤80% of rated power. For inductive loads, use a pure sine wave model.

Which plug types are supported by the universal socket?

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