Running new Tablo off D/C not A/C?

Here’s an off the wall question. I’m testing running a new Tablo 4 tuner off of a Ecoflow battery. I can simply plug it into AC and it works just fine. But when you do that the AC inverter runs 24/7 and has quite a overhead electrical drain. (as I understand it)

But things you run off DC do not. Is there a way to run this off 12v (cigarette type) port or off USB C or USB A? .
