Refrigerators use a compressor, and when it starts up, it draws a surge of power that is much higher than its normal running wattage. This startup surge is typically three to seven times higher than the rated power, though the exact amount varies by brand and model.
Because of this, a portable power station can only run a refrigerator if the unit’s surge or startup power is within the power station’s rated output.
To be on the safe side, we recommend checking with the refrigerator manufacturer to confirm the startup wattage and whether it is compatible with a portable power station.
