How Long Will a Goal Zero Yeti 700 Run an Upright Freezer

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.

Our answer

On our planning profile the Goal Zero Yeti 700 runs an upright freezer 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
VoltageClearsAn upright freezer runs on 120V and the Goal Zero Yeti 700 supplies 115V AC.
Continuous outputClearsA 130W running load sits inside the 600W continuous rating, leaving about 362% headroom.
Startup demandClearsThe 1,000W start sits within the published 1,000W peak.

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 677.37Wh rated here, roughly 536Wh reaches the outlet under a conservative planning model.

That energy meets an average load of 44.9W, which applies a 33% duty cycle to a 130W 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.

  • Neither manufacturer publishes how long the surge is held, so the margin above continuous output cannot be verified against a duration.

Before you rely on this

These limits decide whether this appliance belongs on a portable battery at all.

  • A full freezer holds a safe temperature for about 48 hours unopened. Backup power extends that window but does not remove the need to check the temperature.

Replace our assumptions with your own

Frost-free upright freezers run a periodic defrost heater that draws several hundred watts for a short period. If that cycle lands inside your outage it changes the daily total.

Read the nameplate or data label for voltage and rated amps or watts, then run the appliance through a normal cycle on a plug-in energy meter for 24 hours. Use the measured watt-hours in the calculator instead of the default on this page.
