Source:www.ecoflow.com. Verified 2026-10-05. JP series page states 256Wh, 300W rated, X-Boost up to 450W, LiFePO4 / LFP, 3,000 cycles, 5-year warranty, about 3.5 kg. Weight is left null because the page publishes kilograms, not pounds. The US series page still lists both 240Wh and 256Wh, so this record is sourced from the Japanese page. X-Boost is not treated as inverter surge.
Recorded uses: Camping. Those tags come from the manufacturer positioning on the source page, not from a test.
