EcoFlow RIVER 2 240
The RIVER 2 240 is the RIVER 2 poured to the line instead of the brim: thirteen watt-hours fewer, and otherwise the same 300 watts, the same eight pounds, one manual between them. EcoFlow’s store sells this one now. It clears an afternoon off-grid on under half the tank, and nothing longer. No owner has written in.

03 · From the verdicts
Who it is for, and when a rival won instead
Each line is lifted from a written matchup where it decided the verdict, and links to the page it came from. Repeated across many matchups means it is the unit’s signature, not one author’s opinion.
Buy the RIVER 2 240 if…
You're buying from EcoFlow's own store, where the 240 is the one on the shelf [B0].
You want the small RIVER 2 for phones, a laptop and lights, and would rather not spend an evening tracking down the last original for a 5% bigger tank.
A rival won when…
You've found a new 256Wh RIVER 2 from a seller you'd buy from anyway, and it costs less than the 240. Take it: same box, 13Wh more.
You already own one and wondered whether the 240 is an upgrade. It isn't. It's a slightly smaller tank in the same case.

From the test desk
“EcoFlow documents these two in a single manual, and the specification table splits them on exactly one line: 256Wh for the RIVER 2, 243Wh for the RIVER 2 240 [B1].”

Questions people ask
What is the difference between the EcoFlow RIVER 2 and the RIVER 2 240?
Capacity, and nothing else. EcoFlow's manual covers both units and lists 256Wh for the RIVER 2 and 243Wh for the RIVER 2 240; every other line of the specification table is shared [B1]. The inverter, ports, charging speed and 5-year warranty are the same.
Is the RIVER 2 240 actually 240Wh?
No, it's 243Wh. The listing title and the SKU say 240, but EcoFlow's manual and its own product page both give 243Wh [B1][B5]. It's one of the few products named slightly below its real capacity.
