256 Wh published capacity. Continuous AC output 300 W, with 600 W listed as surge or boost.EcoFlow's EU product page lists 256 Wh, a pure sine wave AC output of 300 W total with a 600 W surge, and 230 V outlets. X-Boost up to 600 W is that surge mode, not a second continuous rating. RunTime treats 300 W as the continuous AC limit.

AC rows use 85% efficiency, a planning assumption, because this page's source does not print an inverter efficiency. DC rows use the full 256 Wh. A cycling load, especially a fridge compressor, will not match a steady watt.
