Starlink power consumption by model
PUBLISHED SPECIFICATIONSChoose your hardware carefully. Standard Actuated and Standard 4 have different power needs, even though both are often just called “Standard.”
| Starlink kit | Average power | Source |
|---|---|---|
| Mini | 25–40 W | Starlink |
| Standard 4 / 4 X | 75–100 W | Starlink |
| Standard Actuated | 50–75 W | Starlink |
| V5 | 35–50 W | Starlink |
The Mini preset uses its specification sheet. The power help article gives a wider 20–40 W range and describes its figures as AC input averages for the complete kit. For a different power path or measured setup, enter your own watts. V5 has a separate manufacturer comparison.
How the calculator works
CALCULATION METHOD÷ average watts
A 512 Wh battery, with 20% held back and 85% delivery efficiency, leaves about 348 Wh for the kit. At the Mini midpoint of 32.5 W, that’s roughly 10 hours 43 minutes.
To size a battery, the calculator reverses that formula using your daily hours as the target. The high-draw figure is a more conservative starting point. Extra devices add to both runtime demand and electricity use.
Daily energy is watts × hours ÷ 1,000. Monthly electricity cost is daily kWh × 30 × your tariff. Those costs use published wall-input averages and don’t apply the battery efficiency setting again.
Battery output requirements
Check your battery’s voltage, continuous power rating, and cable compatibility before connecting Starlink. For Mini USB-C use, follow Starlink’s power-source requirements. The average draw used here does not size an inverter for startup or snow melt.
