Starlink Standard 4 (Gen 3 hardware) Runtime Estimate

Snow melt, boot, heat, router behavior, and network activity can change draw. This profile is scoped to Standard 4 (Gen 3 hardware); V5 has a separate, lower official range.

Use this load in the runtime calculator

Planning wattage range

75-100 W. Use a measured average when the device matters.

Planning default

85 W at 100% duty cycle, or about 85 W average load.

Confidence label

Estimated. Treat the result as a planning estimate, not a lab measurement.

1,024 Wh example

With 85% efficiency and a 10% reserve, about 783 Wh remains usable. At the default load, that is roughly 9h 13m.

Published device values and editorial calculator assumptions have different evidence. An editorial range is a starting input, not a measured category range; replace it with your device reading. Context links explain units or compatibility and do not prove the numbers. The check date records the evidence classification, not a new hardware test.

Device measurement guide

Use the measured average

Enter a steady watt reading or a full-cycle average in the runtime calculator. Use 100% duty cycle for an average that already includes on and off periods.

Device wattage (W)
Read watts after a steady load settles; record energy over time for a cycling load.
Duty cycle (%)
Average watts calculated from Wh divided by hours already include off-cycle time, so do not apply duty cycle again.
How to Measure Device Watts for Runtime Planning
Use this load in the runtime calculator

Verify your watts

  • Check the device label for running watts or input amps and volts.
  • Use a plug-in watt meter for AC loads when the result matters.
  • For cycling loads, measure long enough to capture on/off behavior.
Open wattage library

Check output path

  • AC inverter loads usually lose more energy than direct DC loads.
  • Keep reserve for cold weather, battery age, and load changes.
  • Do not treat label capacity as fully usable watt-hours.

How to use this scenario

  • Start with 85 W if you do not have a watt-meter reading yet.
  • Starlink Standard 4 (Gen 3 hardware) is treated as a continuous load, so runtime is sensitive to the real wattage you enter.
  • Keep at least a planning reserve because battery age, temperature, output path, and device settings can move the result.

Watch-outs

  • The scenario wattage is an estimate. Measure the real load before relying on it for outage, travel, or critical planning.
  • Satellite internet draw can move with boot, firmware, heat, sky view, cable losses, and network activity.
