>>yes its for audio equipment

More specifics please. Schematic diagram of equipment would be ideal.

No diagram, but this is what wants the power.

>18v AC input
>fucking bullshit

Open it up and replace the power circuit with some 9 volts and a boost converter.

or get a decent audio interface that actually has phantom power

I don't have decent audio interface, I'm just a normal guy who has a laptop and a DSLR.

>only high end audio mixers or other bullshit have phantom power apparently.

>>1145008
Boost converter is for DC to DC power.

I'm talking DC to AC.

>>1145012
not him, but my 40 dollar mixer has phantom power

>>1145014
Ah gotcha. Will look into, thanks.

Make/model?

You need an inverter if you want to convert DC to AC. Most of the cheap small ones on eBay use a 12VDC input though.

Were you born retarded or were you in some sort of accident?

>two 9v batteries make 18v in parallel

Take a look at that adapter current rating. Even if the powered device only uses a part of that, 9 volt batteries aren't going to last very long.

You need to do some research on the current requirements before you can make a decision on how to power that thing.

The wall wart is extremely overrated. No way that phantom power draws that much. A 9 volt could easily supply enough to keep a condenser working for a few hours.
