so ive got quite a bit of questions about these DC - AC converters, so ive got an inverter wich converts 9V DC alcaline battery to around 240V AC output, my questions are, is this circuit realy useable, because i see videos on youtube a 9v battery can power 120v or 240v light boulbs, so im wondering would this be a heavy load on the 9v battery, is this realy useable, can it realy power devices like a computer monitor or such, ik it sounds crazy, so please explaine to me why this type of circuit is bad and whats wrong with it, my worry is that its to of a heavy load for the battery and the battery would expload! here's the datasheet of the inverter component https://www.electronicsdatasheets.com/manufacturers/endicott-research-group--erg/parts/lps0935

The power supplied by a DC->AC converter to its load comes from the DC input.
The part you've chosen, an LPS09-3-5, is designed for driving an EL panel, rated at 5 unit loads. In this case, a unit load is defined as 20nF//100kohm, taking 6.1mA at 120v rms at 400Hz. The specification goes on to say that each unit load requires 500mW of input power from the battery. I notice the VA of a unit load is 730mW, which confirms the low power factor of the load.
Will the output of 120v 30mA 400Hz (into a 100nF//20kohm load) do what you want it to?
How long will your 9v battery last delivering 2.5 watts?
