EcoFlow RIVER 3 Plus Portable Power Station
The EcoFlow RIVER 3 Plus combines 286 Wh of battery capacity with 600 W of continuous AC output, making it a compact option for modest portable loads. Independent testing does not support treating the promoted 1,200 W X-Boost figure as real-appliance capability, so buyers should size devices against the verified 600 W output.

|---|---|---|---|
| Goal Zero Yeti 700 Portable Power Station | Both units have 600 W verified AC output, but the EcoFlow has 286 Wh capacity versus 677.376 Wh in the Goal Zero Yeti 700 evidence. [3], [2] | Pick the EcoFlow for a smaller-capacity 600 W use case; consider the Yeti 700 when substantially more stored energy is required at the same output rating. |

EcoFlow RIVER 3 Plus: compact 600 W portable power
Battery capacity
The RIVER 3 Plus has a verified battery capacity of 286 Wh, defining the stored-energy budget for portable use. [2]
Continuous AC output
Its verified continuous AC output is 600 W. Buyers should compare appliance input requirements directly with that figure. [3]
X-Boost limitation
Independent testing does not support relying on the 1,200 W X-Boost claim for real appliances. The 600 W continuous rating is the safer planning figure. [3], [1]
