EcoFlow specs

18 current models in the verified database. 7 of these publish a resistive boost figure instead of an inverter surge, so a fridge compressor is not treated as cleared on those rows.

Against a full-size fridge at 150 W running, 35 percent duty, and 1,200 W startup (an estimated engineering range, not a measurement), 9 of 18 clear every limit.

Specifications taken from manufacturer pages. A peak marked "boost, not surge" is a resistive-load rating and is not used to clear a motor start. Each model page lists its source URL and verification date.
