How Long Will a Goal Zero Yeti 500 Run Starlink Mini

This estimate separates electrical compatibility from battery endurance. Published specifications control where they exist, and every planning default is labelled where the manufacturer leaves a gap.

Research by the Power Station Station Editorial Team

Estimated runtime
12 hours
From 499.2Wh rated capacity against a 33W average load.
Continuous output
500 W
What the inverter can sustain. Output decides whether the appliance runs at all.
Published peak

Manufacturer surge figure, used only for the startup check.

Our answer

On our planning profile the Goal Zero Yeti 500 runs a Starlink Mini for about 12 hours, or 9.6 hours if you keep a reserve back.

The checks behind this answer

Stored energy is the final check, not the first. Voltage, continuous output, and startup demand must clear before runtime means anything. Missing published evidence stays marked unverified instead of being treated as a pass.

Electrical checks applied to this station and appliance pairing
CheckResultWhy
VoltageClearsA Starlink Mini runs on 120V and the Goal Zero Yeti 500 supplies 115V AC.
Continuous outputClearsA 33W running load sits inside the 500W continuous rating, leaving about 1415% headroom.
Startup demandClearsThe 65W start is covered by continuous output alone, so no surge rating is needed.
Inverter self-consumptionUnverifiedThis is a long, low-power load, so the inverter's own draw materially changes the answer. That figure is not published for this station.

How the number is built

A battery holds back some of its rated capacity, and converting to household AC costs more on top. Of the 499.2Wh rated here, roughly 395Wh reaches the outlet under a conservative planning model.

That energy meets an average load of 33W, which applies a 100% duty cycle to a 33W running draw. Holding back a 20% reserve for battery age, cold, and a longer outage leaves 9.6 hours. These are calculations, not measurements from a test.

What we could not verify

These gaps are in the published evidence, not in the arithmetic. Each one is a reason to check before you depend on this pairing.

  • Inverter self-consumption is not published, and it matters more than the appliance load on a run this long.

Replace our assumptions with your own

Average consumption rises when the terminal is searching for satellites, melting snow, or operating in heat. A terminal with a clear view of the sky settles to a lower steady draw than one fighting obstructions.

Use the Starlink app to read current power draw over a full day of your own usage, or meter the power supply at the outlet.
