The Starlink modems pull about 100 watts. As far as I know, the cell uplink service being discussed in this article does not use the Swarm network, and the phones utilizing this new service will not be running at 100w. This is a new satellite based low-power 4g/5g service that slots in somewhere between Starlink internet and Swarm's offering, and it seems to be integrated into the Starlink network. It is cheap enough to lump into cell plans, is compatible with sub $100 phones, and seems to have the capacity for much higher bandwidths.
Also, the Starlink modems need a huge amount of power compared to the Swarm network, not really a similar application.
