Does Starlink work without electricity?

Starlink keeps working in an outage only if the dish and router stay powered. Here’s how long each option lasts.

  • Numbers checked
Quick answer

No, it needs power. The Standard dish draws about 75–100 W Official spec: From a Starlink specification sheet or help article. Checked Oct 5, 2026 including the router. Keep it on a UPS, power station or generator and it keeps working when the grid is down; the satellites don’t care about your power cut.

Your options

OptionGood forWrong when
UPSRiding through flickers and short outages with no gapOutages last many hours: small UPS batteries run a dish for minutes to an hour
Power stationHours to a day; many switch over fast enough to act as a UPSMulti-day outages without a way to recharge
GeneratorMulti-day outagesYou can’t run it safely outdoors, or need silent overnight power
Solar + batteryLong outages in sunny seasonsWinter in the north, unless sized for December
Swap to a MiniStretching a small battery: 25–40 W Official spec: From a Starlink specification sheet or help article. Checked Oct 5, 2026 vs the Standard’s rangeYour plan doesn’t cover a second dish

Top of Starlink’s average range for each dish; planning assumptions for usable capacity and conversion (methods). Idle is lower (20 W Official spec: From a Starlink specification sheet or help article. Checked Oct 5, 2026 for Standard), so quiet hours stretch it.

Before the outage

  • Put the dish power supply and anything between the router and your devices on backup power, or the connection drops at your end.
  • Test it: switch off the breaker for a minute and watch.
  • Know your runtime: run the numbers.
Generator safety

Run generators outdoors only, far from doors and windows (carbon monoxide). Never back-feed a house through an outlet; that needs a transfer switch fitted by an electrician.

Switching to cellular or a second connection when Starlink itself drops is a different topic (connectivity failover); this page covers keeping the power on.

When this is the wrong choice

  • A big UPS is the wrong buy for day-long outages: per watt-hour, a power station or LiFePO4 battery is usually the better value.

Questions people ask

Does Starlink work without electricity?

No. The dish and router need power the whole time. With a battery, UPS, power station or generator it keeps working through a power outage, as long as the satellites are in view.

How long will a power station keep my home Starlink running?

For a Standard dish at the top of its range through an inverter, a 1,024 Wh station gives about 7 h 36 min and a 2,048 Wh station about 15 h 6 min (planning figures).

Can I run Starlink off a generator?

Yes. Plug the power supply into the generator like any appliance. An inverter generator gives cleaner power; a UPS or power station between them rides through the generator starting and stopping.
