Starlink Mini: Ideal Power Bank + AC/DC Setup for Food Truck Use

I just ordered a Starlink Mini for our soon-to-launch food truck. It will mainly be used for music streaming, remote work connectivity, POS transactions during the day, and providing camera feed/alerts to cloud from an external camera while the truck is parked overnight.

I'm looking for power bank recommendations and an ideal AC or DC setup—preferably under $200—that can reliably power the Starlink Mini for 12–14 hours. The system should support for pass-through charging so the power bank can charge while simultaneously powering the Starlink Mini during the day, without the need to unplug or reconfigure anything.
