Source:www.ecoflow.com. Verified 2026-10-05. Hero card: 858Wh, 600W output, 1200W X-Boost. The same page also describes this as RIVER 3 Plus plus an EB600 extra battery. LiFePO4 and 3,000 cycles are stated for the RIVER 3 Series. X-Boost is described as handling heating devices, so peak_is_surge is false.
Recorded uses: Camping. Those tags come from the manufacturer positioning on the source page, not from a test.
