How Much Power Does Starlink Use?

If you plan to use Starlink for your RV or off-grid cabin, knowing the electrical specifications for Starlink is critical. Even if are just using Starlink at home on the grid, you may be wondering how much power the Starlink dish uses.

In this article, I will explain the power consumption for all three models of the Starlink antenna: Standard/RV, High Performance, and the original round dish. I will also explain the factors that affect power consumption.

Standard and RV Starlink

The Standard Starlink hardware 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, 50-60Hz. It draws up to 2 amps. Currently, Starlink does not offer a DC power supply for Starlink RV.

High Performance Starlink

The 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.

High Performance runs off of 100-240V, 50-60Hz, and draws up to 4.5 amps.

Original (round) Starlink

The original, round Starlink dish uses 65-100 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 40-60 watts.

The round dish runs off of 100-240V, 50-60Hz, and it is estimated to use up to about 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. It will use less power when nobody is downloading or uploading anything.

Weather

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.

Network activity

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.

Obstructions

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.
