Our verdict
The RIVER 3 Plus replaces the RIVER 2 as EcoFlow's small grab-and-go unit, a touch pricier but with X-Boost surge to 1,200W and genuine expandability via EB300/EB600 batteries. Not for kettles or big appliances, but excellent for devices and camping.
Good
- Fast ~1hr full charge
- Expandable to 858Wh
- Light at 4.7kg
Watch out
