The Starlink Mini Power Guide: Battery Runtimes & Solar Sizing
Planning off‑grid internet? Here’s how long a Starlink Mini will run on common battery packs — and how much solar you need to keep it online 24/7. We’ve included real‑world numbers, quick charts, and recommended gear.
Starlink Mini Power Requirements
- Idle: ~20–25 W
- Typical use: ~30–35 W (browsing, streaming, uploads)
- Peak: up to 40 W
Battery Runtime Examples
Rule of thumb formula: Runtime (hours) = Battery Wh ÷ Power (W), minus ~10–15% system losses.
| Battery | Capacity | Practical Runtime @30 W | Practical Runtime @35 W |
|---|---|---|---|
| 100 Wh pack | 100 Wh | ~2.8–3.0 h | ~2.3–2.5 h |
| Jackery 300 | 293 Wh | ~8.3 h | ~7.1 h |
| EcoFlow River 2 Pro | 768 Wh | ~22.0 h | ~18.7 h |
| Jackery 1000 Plus | 1002 Wh | ~28.7 h | ~24.4 h |
| Anker 757 | 1229 Wh | ~35.2 h | ~30.8 h |
How Much Solar for 24/7 Starlink?
To run continuously, size panels for your daily energy use. Use ~15% for system losses and a 0.75 derate for real‑world panel output. We will be using Phoenix Arizona in this example.
Recommended Kits & Panels (From Our Store)
Jackery Solar Generator 1000 Plus
~1,264 Wh LiFePO₄ capacity with expansion options — enough for a full day of Starlink Mini, plus phones and laptops.
Jackery SolarSaga 100 Light
Portable 100 W panel; combine two or three for a 200–300 W array that sustains Starlink Mini in most seasons.
Jackery SolarSaga 100 Prime
DIY‑friendly 100 W panel with accessories; great for roof or rack mounting in overland builds.
Jackery SolarSaga 200W
High‑efficiency 200 W bifacial panel; pair with the 1000 Plus for robust 24/7 connectivity.
Jackery 1000 Plus Expansion Battery
Add 1,264 Wh to your 1000 Plus system to extend runtime through cloudy stretches.
Pro Efficiency Tips
- Use DC‑to‑DC where possible to avoid inverter losses.
- Keep panel cables short and properly sized to minimize voltage drop.
- Angle/tilt panels seasonally; keep them cool and clean.
- Track consumption with a small inline wattmeter to validate assumptions.
Bottom Line
A Starlink Mini typically draws 30–35 W. Expect ~2–4 hours on a 100 Wh pack, ~7–10 hours on a Jackery 300, and a full day or more on a 1000 Plus. For 24/7, budget 250–300 W of solar in Phoenix with a 700–1000 Wh battery buffer.
