I'm trying to determine the power capacity (in hours/minutes) of a cordless Pedaltrain Volto unit (a rechargeable power supply) on my pedalboard.

If I turn on all the fx boxes and walk away, will this tell me anything or do the pedals need to be processing signal to get a real world test of the duration of the power pack charge?

The board consists of dirt pedals, eq, delay and modulation, a mix of digital and analog.

I might be misunderstanding, but you can actually just calculate it all directly.

Every pedal should (normally) publish the mA it uses/requires. And the Volto for sure publishes the peak mA it can supply.

I think I got my answer elsewhere but let me rephrase.
You and me side by side, identical pedalboards with everything turned on. You hold your guitar and do nothing. I play power chords for 30 minutes. Is my Volto more drained than yours?
I have been told that no, on is on and it doesn't matter if they are being driven or not.

That is correct, as effect units don't have to drive heavy loads - like power amps do. There are effect units that will draw a few percent more power when driven hard, but that's all - won't make a difference in practice.
