The real-world result
My Starlink app statistics showed an average power draw of 28 W during the recorded period. That is a useful real-world figure for my setup, but power use can vary with hardware, temperature, activity, snow-melt conditions and the way the system is used.
To estimate running cost, measure your own system where possible and multiply the average wattage by the hours it runs, then apply your electricity price. Do not assume one customer’s figure will match every kit.
What I learned
Power matters particularly for off-grid, backup and campervan use. Allow for the router, any Ethernet or mesh equipment, conversion losses and safe battery capacity—not just the dish.
What I would do before copying this approach
A stable, efficient installation starts with suitable power and safe cabling. Do not overload a portable inverter or use damaged extensions just to reach a convenient location.
My practical advice
The 28 W figure was an average shown in my Starlink app during a recorded period. It is not a verified measurement of every device at the wall socket, and the duration of that recorded period is not documented here. Do not use it as a universal Starlink power specification.
At a constant 28 W, the arithmetic is 0.028 kW × 24 hours = 0.672 kWh per day, or 20.16 kWh over 30 days. That is a calculation using the reported figure, not a measured monthly bill. Multiply by your own tariff only after deciding which equipment your measurement includes.
Use the power-budget guide and worksheet to record the complete setup and avoid counting a router or power supply twice.
