FAQ:
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.

What appliances can this inverter support?

Rated 1500W, peak 3000W – supports most home appliances.

Can 4 USB ports fast charge at the same time?

Yes, 4 USB ports can fast charge mobile phones, tablets and other devices at the same time, meeting the needs of simultaneous charging of multiple devices.

How does reverse protection work?

When the positive and negative poles of the battery are reversed, the inverter will automatically cut off the circuit to avoid device damage and ensure power usage safety.
