✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
768Wh with 1000W output at $499 — it does what the EcoFlow River 2 Pro does, with more output and more weight.
Best for: Campers who need to run a small fridge, not just charge devices.
What we like
- 1000W output beats the River 2 Pro's 800W
- 500W solar input is strong for this size
- 2000W surge handles small compressors
Where it falls short
- 22 lb — 5 lb heavier than the River 2 Pro
- Not expandable
