FAQ:
Which country’s voltage standards does it support?

It defaults to AC 220V output, suitable for regions with 220V voltage standards such as China and Europe; it can also be customized to output AC 110V, suitable for regions with 110V voltage standards such as the United States and Japan.

Can it drive a 3000W air conditioner?

Yes. Air conditioners have instantaneous power during startup (about 2-3 times the rated power), and this product has a peak power of 6000W, which can meet the startup and operation needs of a 3000W air conditioner; the battery capacity must be ≥150Ah to ensure continuous power supply.

Which regional plugs can be used with the universal socket?

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

What is the benefit of the UPS function? A2:

It automatically switches to battery power when AC fails.
