Battery bank for Dual-axis Turntable

I am looking for a mobile solution for the Dual-axis Turntable, but am having trouble finding reasonably sized and priced USB-C battery pack that can deliver 12 volts at 2 amps. Does the turntable really need 2 amps? that seems like a lot of power for what the turntable is actually doing.

I could probably find a direct 12 volt battery supply to do it, but would prefer a USB solution so that It can also power the scanner and other USB things.
