If you plan to use Starlink for your RV, boat, or off-grid cabin, knowing the electrical requirements for Starlink is critical. Even if are just using Starlink at home, you may be wondering how much power the Starlink dish uses.
In this article, I will explain the power consumption for all models of the Starlink antenna: Gen 1 Standard Circular, Gen 2 Standard Actuated, Gen 2 High Performance, Gen 2 Flat High Performance, and Gen 3 Standard. I will also explain the factors that affect power consumption.

Gen 1 Standard Circular
The original, Gen 1 Standard Circular Starlink dish uses 65-150 watts on average. Starlink didn’t publish the official specifications for the round dish, but I was able to estimate this amount based on my own experience and reports from other users.
Idle usage is between 40-50 watts.
The round dish runs off of AC power, 100-240V, 50-60Hz, and it is estimated to use up to about 5 amps. Power to the Gen 1 dish is supplied through a power brick.
Gen 2 Standard Actuated
The Gen 2 Standard Actuated Starlink dish uses 50-75 watts on average. This includes the antenna, router, power supply, and cables.
When there is no network activity, the Standard Starlink uses about 20 watts to remain connected to the satellite network.
Starlink runs off of 100-240V AC, 50-60Hz. It draws up to 2 amps. On the Gen 2 system, the power supply is integrated within the Wifi router. Starlink does not offer a DC power supply. I did build my own 12V DC power supply, so check that tutorial out if you are interested.
Gen 2 High Performance and Flat High Performance
The Gen 2 High Performance and Flat High Performance Starlink dish uses 110-150 watts on average. This includes the antenna, router, power supply, and cables.
When idle, High Performance uses about 45 watts.
The Gen 2 High Performance models have a separate power supply brick that runs off of 100-240V AC, 50-60Hz. It draws up to 6.3 amps.
Gen 3 Standard
The Gen 3 Standard Starlink dish uses 75-100 watts on average. This includes the antenna, router, power supply, and cables.
When idle, the Gen 3 Standard dish uses about 20 watts.
The Gen 3 Standard model uses a power supply brick that runs off of 100-240V AC, 50-60Hz. It draws up to 2.5 amps.
Factors that affect power consumption
The amount of power that Starlink draws depends on many factors. For example, the Starlink dish will use additional power when it’s snowing or raining. It will use less power when nobody is downloading or uploading anything.
Weather is the biggest factor to consider in terms of power consumption. During rain or snow, more transmitting and receiving power is required, so power usage can increase significantly. The dish will also automatically melt snow and ice, which uses even more power.
Starlink is an antenna that receives and transmits data from satellites orbiting overhead. It takes more power to transmit data than to receive it. If you are uploading data, Starlink will use more power. If you are downloading, Starlink uses less power.
When there is no network activity (idle), Starlink still uses a bit of power, but it is significantly less than when you are downloading or uploading.
If you have trees or other obstructions that block the signal from the Starlink satellites, your Starlink will use more power as it tries to continually re-establish a connection with the satellites.
