Whether you are a Starlink RV, residential or business user, knowing the amount your system consumes is crucial.  

Remember, it is a service introduced to offer high-speed internet connection in remote and populated areas. 

For that reason, you should expect substantial power consumption. So, what exactly does Starlink consume in terms of power?

Starlink power consumption varies depending on the type of dish you have. SpaceX used to offer round dishes but upgraded to rectangular ones with more efficiency.

 The company also introduced high-performance dishes of late, which are more demanding in terms of power consumption.

First-Gen Standard Dish

These are original dishes introduced for beta residential subscribers. The dishes are larger, circular, and not as efficient as the rectangular ones. 

Though their supply is now discontinued, they are still popular among home users. You can still use them without any issues. 

The dishes could consume between 60-110 watts and pull up to 2.5 amps (A) current when running on 100-240 AC power at 50-60 HZ.

 You should remember that power consumption increases during cold weather, and for these dishes, it could go up to 160 watts. 

However, the power consumption significantly drops during the low-traffic phase to 30-40 watts and pulls up in about 5A while running on the standard power supply. 

At rest, the consumption drops further to around 20-30 watts at the 100-240v AC power supply. 

Standard Rectangular Dish ( 2nd Gen)

The new generation standard Starlink dish, which is rectangular, is for residential and RV use. It is more efficient compared to circular dishes.

Though they have lower power ratings, the reported consumption is nearly similar to what circular dish users report. 

The rated power consumption is 50-75W, but most people report around 65-180W. The idle power is 20W, according to company ratings, but some users report up to 40W. 

The power supply requirement is similar to the circular dish, 100-240V at 50-60 HZ, and can pull up to 2A. These figures also apply to Starlink RV power consumption.

There are two types of high-performance Starlink dishes, namely flat and regular high-performance. 

The dishes are available for residential, RVs, businesses, and marine subscribers. The flat high-performance dish is specifically for in-motion Starlink RV use. 

High-performance dishes consume 110 to 150 watts. The dishes also pull a higher current of 4.5 amps while operating on a power supply of 100-240V at 50-60 HZ. 

This applies to Starlink RV power requirements for flat high performance too. 

Factors Affecting Power Consumption of Starlink

The wide range in power consumption can surprise many. However, there are contributing factors that you should learn.

Network Activity

Your network usage is a key factor regarding how much power your Starlink consumes.

 The number of devices and the data they require will impact your power consumption directly. 

The more data the devices require, the more electricity your Starlink will consume. 

The nature of the activity also impacts power consumption. For instance, activities such as video calls, streaming, and downloading large files require more data and, therefore, will consume more power.

 Light activities such as sending emails and browsing use less data and therefore don’t consume much power. 


Starlink can work in a wide range of weather conditions with normal power consumption.

However, extreme weather conditions such as heavy rainfall, cloud cover, and ambient temperature can impact power consumption.

Poor weather, such as cloud cover or precipitation, obstructs signals. In such cases, the dish will have to send stronger signals to be efficient, and this requires more power.

The dish also tends to consume more power during low temperatures than at high temperatures. 

However, snowfall doesn’t interfere with the Starlink power consumption, contrary to what many would think. It has a snow-melting feature that heats the dish surface and melts the ice. 


Natural obstructions such as hills and trees can also impact Starlink signals and, therefore, power consumption. The dish consumes more power when trying to reconnect with the satellites moving in the sky.

The location of the Starlink dish about the satellite constellation affects power consumption. 

The satellite moves freely in low earth orbit. Since they don’t have a fixed position, the dish changes its connections frequently. 

This frequency of disconnection is what leads to power consumption variation. 

If your location has poor satellite coverage, you will likely incur high power consumption. 

However, with several Starlink satellites being set into orbit, this factor will soon cease to pose any problem.

Starlink power consumption is low, as you can see. However, compared to a normal WiFi router which uses around 5-20W power, Starlink certainly consumes more power. 

That said, the average cost of 1 kW/h averages around $0.175. Factoring in this, you should expect to spend around $77-$230 yearly. 

However, the service offers a lot of value, especially to those living in remote areas, as they enjoy nearly similar connections to those in urban areas. For that reason, it is worth it.

Starlink introduced a feature called sleep schedule which can help you control your power consumption.

You can put your dish into sleep mode, and most consumers report that power consumption reduces by 25 watts in this status. 

Another option is unplugging the hardware when not in use. For instance, when traveling. 

Finally, you can purchase direct current (DC) power over an ethernet (PoE) injector. You can cut the power consumption by half when you change it from AC to DC. However, the modification may strip you of your warranty. 

Starlink power consumption is not too high, with a standard one for residential and RV use consuming in the range of 50-75W.

 With this, we can still say the provider is environmentally friendly. 

The consumption depends on various factors, including weather, location, network activity, and obstructions.

 If you think any of these impacts your Starlink power consumption, find a way to fix it. Hopefully, this article was helpful.
