More power won't help you here, I think: Since this uses regular terrestrial LTE bands and modems, you wouldn't be allowed to use any more in the uplink than a regular phone (i.e. 250 or so mW EIRP).

I could see in-car based Starlink usage in the Ka band, though – the Starlink Mini terminal definitely fits the form factor and power envelope.

Okay maybe not more watts, but the same power can be made more directional with a phased array or something I'd assume? (I am not an EE)

EDIT: Oh, I see. EIRP already accounts for directionality and is measured where the antenna gain is highest. Never mind then!
