Runtime calculation

How Long Will an Anker SOLIX C1000 Gen 2 Run a Mini Fridge

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.

Estimated runtime
37 hours
From 1,024Wh rated capacity against a 21.7W average load.
Continuous output
2,000 W
What the inverter can sustain. Output decides whether the appliance runs at all.
Published peak
3,000 W
Manufacturer surge figure, used only for the startup check.

Our answer

On our planning profile the Anker SOLIX C1000 Gen 2 runs a mini fridge for about 37 hours, or 30 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 mini fridge runs on 120V and the Anker SOLIX C1000 Gen 2 supplies 120V AC.
Continuous outputClearsA 70W running load sits inside the 2,000W continuous rating, leaving about 2757% headroom.
Startup demandClearsThe 500W start is covered by continuous output alone, so no surge rating is needed.

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 1,024Wh rated here, roughly 811Wh reaches the outlet under a conservative planning model.

That energy meets an average load of 21.7W, which applies a 30% duty cycle to a 70W running draw. Holding back a 20% reserve for battery age, cold, and a longer outage leaves 30 hours. These are calculations, not measurements from a test.

Replace our assumptions with your own

Compressor and thermoelectric mini fridges behave very differently. A thermoelectric unit draws a steady low load with no startup spike; a compressor unit cycles and surges.

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.
