Our answer
On our planning profile the DJI Power 500 runs a household refrigerator for about 7.9 hours, or 6.3 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.
| Check | Result | Why |
|---|---|---|
| Voltage | Clears | A household refrigerator runs on 120V and the DJI Power 500 supplies 120V AC. |
| Continuous output | Clears | A 150W running load sits inside the 1,000W continuous rating, leaving about 567% headroom. |
| Startup demand | Unverified | The 1,200W start exceeds continuous output, and DJI does not publish a general surge rating for this model. Treat the pairing as unproven until you verify it. |
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 512Wh rated here, roughly 406Wh reaches the outlet under a conservative planning model.
That energy meets an average load of 51.5W, which applies a 33% duty cycle to a 150W running draw. Holding back a 20% reserve for battery age, cold, and a longer outage leaves 6.3 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.
- DJI Power 500 has no published surge rating, so a 1,200W start cannot be confirmed.
- 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 closed refrigerator keeps food safe for about four hours without power. Backup power can extend that, but the temperature still needs checking.
Replace our assumptions with your own
Room temperature, how often the door opens, how full the refrigerator is, the age of the door seals, and whether an automatic defrost cycle falls inside the outage all move the daily energy figure more than the model name does.
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.
