FAQ
What is the maximum pressure of this cordless compressor?
The maximum pressure is 4.1 bar. The target value can be set from 0.2 to 4.1 bar in increments of 0.05 bar.

Does the compressor stop automatically?
Yes. Once the selected pressure has been reached, the compressor automatically stops inflating the connected item.

Can it be used to inflate an airbed?
It is not designed for large-volume inflatables. Its output prioritises pressure rather than the high airflow required by an airbed.
