Cowfish Cosmo – 12V Power Supply for Starlink Gen 3

Stay connected off-grid with the Cowfish Cosmo, the dedicated 12V power solution for your Starlink Gen 3 Dish. Designed by Cowfish Technologies, this compact unit removes the need for an inverter, allowing you to run your Starlink system directly from your caravan or 4WD battery.

Not only does the Cosmo simplify your setup, it also reduces power consumption compared to running Starlink through a 240V inverter. That means greater efficiency, less drain on your batteries, and more time staying connected while travelling in remote areas.

⚡ Why choose the Cosmo?
The Cosmo is a purpose-built power supply that completely replaces the standard Starlink unit. Simply mount it next to your Starlink router, plug it in, and you’re ready to go. With an integrated ON/OFF switch, you can power down your Starlink system when not in use, conserving battery life for longer off-grid adventures. Full control is still available through the Starlink App, so you can manage your system on the go.

🔧 Installation Made Easy
Cosmo is installed directly alongside the Starlink router. Connect the unit to your caravan or 4WD power supply using a minimum of 10 AWG (6.0 mm²) electrical wiring to ensure stable and reliable operation. Once wired in, plug the output into the router and you’re all set.
