Starlink is not a 15 W home router. It is a phased-array dish plus Wi‑Fi, and the draw depends on which kit you own. Size the battery from Starlink’s own average watts — then apply WattList’s usable-Wh rule — or you will over-promise overnight internet.
Quick answer
| Starlink kit (published avg) | On ~1 kWh station (~870 Wh usable) | On AC180 1,152 Wh (~979 Wh usable) |
|---|---|---|
| Mini 20–40 W | ~22–43 h | ~24–49 h |
| Standard Actuated 50–75 W | ~12–17 h | ~13–20 h |
| Standard 4 / 4 X 75–100 W | ~9–12 h | ~10–13 h |
| Performance 110–150 W | ~6–8 h | ~7–9 h |
Formula: Hours ≈ (station Wh × 0.85) ÷ Starlink watts

Starlink watts we use (official averages)
These are AC input averages for the Starlink hardware + Wi‑Fi router + power supply + cables, from Starlink’s support power article and kit specification sheets. Temperature, sky view, snow melt, and utilization move you around the band.
| Kit | Published average | Idle (where listed) | Notes |
|---|---|---|---|
| Starlink Mini | 20–40 W (support); Mini sheet also 25–40 W | ~15 W | Input 12–48 V, 60 W max on DC path |
| Standard Actuated | 50–75 W | ~20 W | Older “actuated” standard class |
| Standard 4 / Standard 4 X / Enterprise | 75–100 W | ~20 W | Current standard residential class |
| Starlink V5 | 35–50 W | — | Newer lower-draw residential option where offered |
| Performance (Gen 1 / Gen 2) | 110–150 W | ~45 W | High-throughput / HP class |
| Flat High Performance (spec sheet) | 110–150 W | — | Same high band on equipment PDFs |
Mini USB-C rule (Starlink): use a 100 W PD source at 20 V / 5 A with Starlink’s USB-C → barrel accessory for best results. Mini will not work reliably with USB PD at 65 W or below.
We do not publish DIY vehicle wiring, fuse sizing, or alternator procedures. If you use a brand DC cable or Starlink’s DC accessories, follow the manufacturer.
The WattList formula
- Start with nameplate Wh on the power station.
- Take ~85% usable for AC inverter + BMS overhead (
Wh × 0.85). - Divide by Starlink’s average watts for your kit.
Hours ≈ (Wh × 0.85) ÷ Starlink_W
Wh_per_day ≈ Starlink_W × 24| Kit average | Wh / day (continuous) |
|---|---|
| Mini 20 W | 480 Wh |
| Mini 40 W | 960 Wh |
| Standard Actuated 50 W | 1,200 Wh |
| Standard Actuated 75 W | 1,800 Wh |
| Standard 4 @ 75 W | 1,800 Wh |
| Standard 4 @ 100 W | 2,400 Wh |
| Performance @ 110 W | 2,640 Wh |
| Performance @ 150 W | 3,600 Wh |
A ~1 kWh station covers a Mini day comfortably at the low end, and struggles for a full Standard 4 day without solar top-up. That gap is the whole point of this guide.

What these hours are not
- Not a lab measurement of your exact dish on your exact night.
- Not including a fridge, laptop, or phone stack — add those Wh separately.
- Not DC-path magic: a proper DC supply can cut inverter loss, but only with the right Starlink / station accessories.
- Not medical or life-safety advice.
If Standard 4 is your kit and you need 24 h of Starlink with margin, plan ~2 kWh of nameplate (or ~1 kWh + serious daytime solar). Mini owners can often live in the ~1 kWh class.

FAQ
Can a normal USB power bank run Starlink? Usually no for Standard kits. Mini wants 100 W USB-C PD (20 V/5 A) with Starlink’s cable — most phone banks are not that.
Should I use the homepage “45 W” Starlink toggle? Treat that as a rough midpoint for mixed Wi‑Fi loads. For Starlink shopping math, prefer the kit-specific ranges above.
Does snow melt ruin the estimate? It can. Mini sheets list snow-melt class draws around 60 W; Standard kits climb when heaters run. Budget the high end of the average band in winter.
AC180 or Jackery 1000 v2 for Starlink camping? Same ~1 kWh class. Pick AC180 for max Wh/$ and ports; pick 1000 v2 if carry weight wins. For Standard 4 all-day + margin, look at 2 kWh class or solar.
Bottom line
Read your Starlink kit’s published average watts, shrink the battery by ~15% for AC usable Wh, then divide. Mini and Standard 4 are different animals on the same 1 kWh station — roughly a day-plus vs a workday.
