How Much Power Does Starlink Use? Watts, kWh and Planning Tips

If you are thinking about Starlink for a home, workshop, cabin or vehicle, power draw is one of the first practical questions. It decides how big a battery or inverter you need, and it gives a rough idea of what the dish adds to your electricity use. The good news is that Starlink publishes average power figures for each kit, so you do not have to guess.

The short version: Starlink lists an average of 75 to 100 watts for the current Standard kit and 25 to 40 watts for the Mini. An earlier Standard kit was listed at 50 to 75 watts. These are averages, not guarantees for every minute of operation.

What the published figures say

Starlink's specification sheets give one "Power Consumption" line for each kit:

The figure is described as an average, so your own draw may be higher or lower than the listed range at any given moment.

Standard kit: planning around 75 to 100 watts

The current Standard specification lists an average of 75 to 100 watts. The kit's power supply is rated for 100 to 240 volts AC, so in normal use it plugs into a household outlet.

For planning, it is sensible to use the top of the range. If you size a battery or generator for 100 watts, you leave room for busy periods instead of assuming the lowest figure.

Because the figures are published in watts, you can turn them into energy with simple arithmetic:

• 100 W for 1 hour is 100 watt-hours (0.1 kWh).
• 100 W for 10 hours is 1,000 watt-hours (1 kWh).
• 100 W for 24 hours is 2,400 watt-hours (2.4 kWh).

These numbers are an idealised calculation. They do not include the losses in an inverter or charger, and they do not include other equipment you might run alongside the dish.

Mini: planning around 25 to 40 watts

The Starlink Mini is listed at an average of 25 to 40 watts. Its input rating is listed as 12 to 48 volts at 60 watts, which is the input range listed on the sheet. That rating alone is not a complete vehicle-installation guide. The same specification sheet also lists a power supply rated for 100 to 240 volts AC, so the Mini can run from a household outlet as well.

Using the same arithmetic as above, 40 W for 24 hours is 960 watt-hours (0.96 kWh). Again, treat that as a planning estimate, not a measurement.

If you want to know more about powering the Mini from a 12 volt source, see our separate guide on running a Starlink Mini on 12V power.

From watts to an electricity cost

Many people searching "how much electricity does Starlink use" really want a monthly cost. The method is straightforward:

1. Take the average wattage.
2. Multiply by the hours the dish is on per day.
3. Divide by 1,000 to get kilowatt-hours (kWh) per day.
4. Multiply by 30 for a rough month.
5. Multiply by the rate on your electricity bill.

As a worked example of the arithmetic only, a dish averaging 100 W for 24 hours uses 2.4 kWh a day, or about 72 kWh over 30 days. The same calculation at 40 W gives 0.96 kWh a day, or about 29 kWh over 30 days. Your electricity rate is the missing piece, and it varies widely by region and by tariff, so we do not quote a price here. Look at the per-kWh rate on your latest bill and multiply.

Why your real number may differ

Several things can make a real installation draw more or less than the published average:

• Snow melt. The specification sheets list snow-melt capability, up to 40 mm per hour for Standard and up to 25 mm per hour for Mini. They do not say how snow melting affects the average figure, so check your own readings in winter.
• Other equipment. The dish figure does not include a separate switch, access point, mesh node, or anything else you plug in.
• Conversion losses. If you run the dish from a battery through an inverter, the inverter itself uses power and wastes some as heat.

The most reliable way to learn your own number is to put a plug-in power meter between the outlet and the power supply and read the energy used over a few days. For a DC system, a DC power meter does the same job.

Sizing a battery: a few cautions

It is tempting to divide a battery's advertised capacity by the dish's wattage and call that the runtime. In practice, usable capacity is lower than the label because of the battery's discharge limits, cold temperatures, cable losses and any inverter in the path. Treat the result of that division as an upper bound and leave a reserve.

If you are building a fixed off-grid system with solar panels, a charge controller and a battery bank, consider asking a qualified electrician or a reputable solar installer to check the design. Wiring, fusing and cable sizing are safety matters, and the right answers depend on your equipment and local rules.

A quick checklist

1. Identify which kit you have: current Standard, earlier Standard, or Mini.
2. Look up its published average power consumption on the specification sheet.
3. Plan with the upper end of the range.
4. Add any router, switch, access point or inverter separately.
5. Convert watts to watt-hours by multiplying by hours of use.
6. Allow for losses and keep a reserve.
7. Measure the real system with a power meter before you rely on it.

The bottom line

Starlink's published averages are 25 to 40 watts for the Mini, 50 to 75 watts for an earlier Standard kit and 75 to 100 watts for the current Standard kit. That puts a continuously running Standard dish at roughly 1.8 to 2.4 kWh per day by arithmetic, and a Mini at roughly 0.6 to 0.96 kWh per day. Confirm your exact model, check the current specification sheet, and measure your setup for the number that matters to you.
