Battery for the quad cortex

I’m trying to cut the wire for gigs and I got a battery pack

and this reversed polarity cable

from my old setup.
I can set the battery to 12 v.
Is it save to use with the quad cortex?
Answers would be greatly appreciated.

Looking at the specs, at the 12V setting, it can output a total of 4 amps, which would be more than enough to power the Quad Cortex. I’m not sure if that’s split across multiple outputs like with something like the Cioks DC7 or if one output can draw the full power, though. I’d recommend reaching out to to get a more informed opinion on it, though.
