Starlink Mini in the cold: power draw & battery runtime
Fall hunting, cabin weekends and winter work all mean running a Mini off a battery in the cold. Here's what Starlink's official spec sheet says, and how to plan power for an NL trip.
- Average draw 25–40W; 60W maximum input
- Runs on 12–48V DC, or 100W USB-C PD with Starlink's cable
- Rated -30°C to 50°C, IP67 with the DC cable installed
- Melts up to 25 mm (1 in) of snow per hour

Starlink's Mini spec sheet lists average power consumption of 25–40W, an input rating of 12–48V at 60W, and a USB-C Power Delivery requirement of at least 100W (20V/5A) when using its USB-C to barrel jack cable. The dish and power supply are both rated from -30°C to 50°C, the dish is operational in winds of 96 km/h+, and it can melt up to 25 mm of snow per hour (Starlink spec sheet).
Runtime math
Battery runtime is roughly watt-hours ÷ watts. With losses included, approximate runtimes are:
- 300Wh station: approximately 7–11 hours
- 500Wh station: approximately 11–18 hours
- 1,000Wh station: approximately 22–36 hours
These are estimates, not test results. Heavy use, snow melt, and cold batteries all push you toward the low end.
Cold-weather tips for NL
- Run on DC (12V or USB-C PD) rather than through an AC inverter to cut wasted power.
- Keep the battery inside the cabin, tent or truck; lithium batteries give less capacity when cold.
- Snow melt draws extra power. Clear heavy snow by hand when you can.
- Turn the Mini off overnight if you don't need it, rather than letting it run idle.
- Check your northern sky view in the Starlink app before you set up.
Rent it ready to go
A Starlink Mini rental is the easy way to try this on your own trip. Add the Boondocker Power Pack (power station plus 100W solar panel) if you don't have a battery. For more detail, see powering a Mini from your truck and the power runtime calculator.
Frequently asked
Starlink rates the Mini and its power supply for -30°C to 50°C. That covers almost all Newfoundland winter conditions, though batteries powering it lose usable capacity in deep cold.
Divide the station's watt-hours by the Mini's average draw (25–40W), then allow for conversion losses. A 500Wh station works out to approximately 11–18 hours of runtime, less in cold weather or when snow melt is running.
Yes. The Mini accepts 12–48V DC (60W max input). Running from DC avoids the losses of converting battery power to 120V AC and back.
