EcoFlow RIVER models compared
Compare every compact EcoFlow RIVER model we track, across both generations, including the measurable step from base to Plus.

01
What separates the EcoFlow RIVER line
RIVER is the carry line — EcoFlow’s answer to the bag-sized end of the market, where mass matters more than output.
What the manufacturer claims
Manufacturer claims are attributed below. Our analysis follows alongside.
EcoFlow markets RIVER as its portable series for travel, camping, and light backup, at the small end of its capacity range.

What the RIVER units we track show
Computed from the sourced specifications of the models in our catalogue — a deliberately selected slice of what this brand sells, never the full lineup.
The five RIVER units in this published comparison span two generations, 245 Wh to 716 Wh and 3.5 kg to 7.8 kg. The instructive pair is the RIVER 3 against the RIVER 3 Plus, because the 41 Wh of extra capacity is not what separates them: the Plus doubles continuous output to 600 W, doubles surge to 1,200 W, doubles solar input to 220 W, and adds expansion — for 1.18 kg. That is why it scores 65.1 against 54.9 despite the near-identical battery. Across the whole family only that one unit expands, and the RIVER 2 sits within 11 Wh and 40 g of the RIVER 3 it was replaced by, so the generation number is doing less work here than the suffix is.

This page owns family and generation-chart intent. It goes deeper than the brand hub but sends exact two-model decisions to head-to-head pages and deal queries to price history.

Frequently asked
- Is a RIVER enough for camping?
- For phones, lights, a laptop, and a fan, comfortably. For anything that heats or cools — a kettle, a compressor fridge running continuously, an electric blanket — the constraint is the 300–600 W sourced continuous rating, not the battery. Check the running watts of what you actually intend to plug in first.
- Why does the smaller RIVER score lower than a heavier station?
- Because the composite rewards output, charging, and longevity alongside capacity, and it does not adjust for size class — the by-size comparison is where you see a unit against genuine peers. A carry-size station and a home-backup station are not competing for the same job even though both appear in the same score range.
- How do I size a station for my own load?
- Size against the devices and duration you actually need, then leave margin for conversion losses and startup surge. Calculate your size →
- Can I compare two exact models?
- Yes — exact model-vs-model pages own head-to-head decisions and keep those queries separate from this family overview. Open model comparison →
