Max current input for the for a VM188

Good evening,
I have a quick question about the VM188. I plan on using it, along with a 120mm computer fan, and a 12v battery pack to create a self contained unit to provide timed airflow in a humidor. My question is this… The battery pack I am planning to use to power both the VM188 and the fan is 2000 mAh. Is this too much current to power the timing module (input to the green 12-24 VDC terminal) if I set it up in the low voltage configuration? Thank you for the help.

Current is not an issue.
The unit only draws the current it needs.
