How long can the inverter run on battery power?

The runtime on battery power depends on the battery capacity and the power consumption of the connected devices. For example, a 12V 100Ah battery can theoretically power a 100W device for approximately 12 hours (assuming 100% efficiency, which in practice will be slightly less due to conversion losses).

Is the inverter suitable for use with sensitive electronics?

Yes, the inverter provides a stable and clean output, making it suitable for sensitive electronics such as computers and medical devices. However, always ensure that the power requirements of your devices do not exceed the inverter's capacity.
