Starlink battery planning
Estimate how long a portable power station can run Starlink hardware and calculate the battery capacity required for a target runtime.
Choose your Starlink hardware and power station capacity to estimate runtime, or calculate the battery capacity needed for a target number of hours.
In battery-size mode, compatible power stations are shown only when they meet the calculated capacity requirement.
Open the general appliance calculatorThis table uses the same calculation functions as the calculator above with a 1000Wh battery, 100% charge, 95% battery health, 10% reserve, and 88% efficiency.
| Starlink model | Official average power | Estimated runtime with 1000Wh |
|---|---|---|
| Starlink Mini | 20-40 W average | 18 hr 49 min - 1 day 13 hr 37 min |
| Standard Actuated (legacy) | 50-75 W average | 10 hr 2 min - 15 hr 3 min |
| Starlink V4 / Standard 4 | 75-100 W average | 7 hr 31 min - 10 hr 2 min |
| Standard 4 X | 62 W average | 12 hr 8 min |
| Starlink V5 | 35-50 W average | 15 hr 3 min - 21 hr 30 min |
| Starlink Enterprise | 75-100 W average | 7 hr 31 min - 10 hr 2 min |
| Performance Gen 1 / Gen 2 | 110-150 W average | 5 hr 1 min - 6 hr 50 min |
| Performance Gen 3 | 70 W average | 10 hr 45 min |
Official Starlink averages vary by hardware: Mini is listed at 20-40 W, Starlink V5 at 35-50 W, V4/Standard 4 and Enterprise at 75-100 W, Performance Gen 1 / Gen 2 at 110-150 W, and Performance Gen 3 at 70 W average.
Many Starlink entries publish average power bands instead of one guaranteed wattage. For those models, the calculator shows the shorter runtime at the higher watt figure and the longer runtime at the lower watt figure. Point-value models show one estimate.
Starlink Mini is the lowest-power category here at 20-40 W average, making it a practical fit for smaller batteries, camping, RV, and portable off-grid use.
Starlink V5 is listed by Starlink at 35-50 W average, lower than V4/Standard 4. Select V5 only if your hardware is the newer V5 kit.
Standard Actuated legacy kits use 50-75 W average. Starlink V4 / Standard 4 and Enterprise use 75-100 W average, while Standard 4 X is separated because a current model-specific Starlink page lists 62 W average.
Performance Gen 1 / Gen 2 remains useful for existing owners at 110-150 W average. Performance Gen 3 is a current entry with a 70 W official average.
Starlink's support values are AC input averages. If your setup runs through an inverter, efficiency and conversion losses matter. DC operation can change real-world results depending on the hardware and cable.
Network activity, temperature, hardware revision, snow-melt operation, battery condition, inverter losses, and other connected loads can all move runtime away from the estimate.
Keep a reserve so the power station is not fully depleted, and include phones, lights, routers, or medical devices separately in the main calculator when they share the same battery.
For travel or remote work, calculate the conservative end of the range, then add margin for cloudy days, cold weather, device charging, and longer sessions.
Results are estimates, not guaranteed runtime. Actual runtime can vary because of network activity, temperature, hardware revision, snow-melt operation, battery condition, inverter losses, and other connected loads.
Need to combine Starlink with lights, refrigerator, CPAP, router, or laptop loads? Use the main power station runtime calculator.
