Head-to-head test
EcoFlow RIVER 2 vs EcoFlow RIVER 3 230
Neither is sold by EcoFlow any more, and they were near-twins anyway: 26Wh more battery on the RIVER 2 against a 100W USB-C port and a tighter UPS class on the RIVER 3 230, so keep whichever you own and shop the successors, the RIVER 2 240 or the RIVER 3 PLUS.

Spec deltas
Both of these have left EcoFlow's store. What EcoFlow sells in the RIVER 2's place is the RIVER 2 240, the same unit with a slightly smaller battery. The RIVER 3 230 survives only as marketplace listings, and the smallest RIVER 3 EcoFlow still stocks is the RIVER 3 PLUS. Nothing on this page can be bought new from the maker, so the verdict is a tie and the useful question is which successor.
If you own one, or you've found stock, the comparison still holds, and it's closer than the generation gap suggests. Same 300W inverter with 600W surge, same 7.8 lbs, same 110W solar input, same 3,000-cycle rating, same socket count. Set them side by side on a desk and you're comparing fine print.
The fine print splits two ways. The RIVER 2 holds 256Wh to the RIVER 3 230's 230, about 11% more. The RIVER 3 230 answers with a 100W USB-C port against 60W, a UPS transfer rated ≤20ms against ≤30ms, and a published noise ceiling where the RIVER 2 publishes nothing. Neither edge is big enough to justify trading one for the other.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
The one scenario where that shows is the CPAP night, and it shows as when you run out, not whether: the RIVER 2 gets about 68% of the way through, the RIVER 3 230 about 61%, and neither sees morning. Extra battery that doesn't finish the job is a later alarm, not a different outcome.
both: 300W output, 600W surge, 7.8 lbs, 110W solar input, 3,000 cyclesRIVER 2 256Wh vs RIVER 3 230 230Whusable after the flat 85% derate: 218Wh vs 196WhCPAP Overnight needs 320Wh: RIVER 2 covers about 68%, RIVER 3 230 about 61%
Why it mattersAn owner of either unit has no capacity reason to trade for the other.
Both of those are desk specs. A laptop that wants more than 60W charges slowly or barely holds steady on the RIVER 2's port, and a ≤30ms transfer is the class many desktop power supplies won't ride through, where ≤20ms is fine on paper for routers and most electronics. The RIVER 3 230's advantages all show up at a desk, not at a campsite.
USB-C: 60W on the RIVER 2 vs 100W on the RIVER 3 230UPS transfer ceiling: ≤30ms on the RIVER 2 vs ≤20ms on the RIVER 3 230identical socket counts: 2 AC, 1 car outlet, 2 USB-A, 1 USB-C
Why it mattersIf your RIVER 2 is guarding a computer or feeding a hungry laptop, that's where its age shows, and the fix is a current unit rather than a second-hand twin.
The bedside is exactly where both units run dry before dawn. Quiet is a nice tiebreak for a nightstand phone charger and a moot one for a CPAP plan, because the right CPAP answer is a bigger battery, not a quieter small one.
RIVER 3 230 publishes 30 dB as a ceiling reached at high charge or discharge rates; the RIVER 2 publishes no figurea comparison review says the RIVER 2 runs noticeably louder under loadA1B1neither covers a full 320Wh CPAP night
Why it mattersCPAP users should skip both rather than pick the quieter one.
So the choice this page used to settle no longer exists in EcoFlow's store. At this size, EcoFlow sells one thing, the RIVER 2 240. The RIVER 3 platform now starts a step larger, with the RIVER 3 PLUS.
RIVER 2 retired; successor RIVER 2 240, the same unit with a slightly smaller batteryRIVER 3 230 retired; successor RIVER 3 PLUS, the smallest RIVER 3 EcoFlow still sells and a size upthe RIVER 2's only hardware lead over the RIVER 3 230 is capacity, 256Wh vs 230Wh
Why it mattersWant this size new from EcoFlow: the RIVER 2 240. Want the newer platform and can carry more: the RIVER 3 PLUS.
The specific dimensions that decide these two units — everything else is a tie.
What the Specs Don't Tell You
Selected because: The UPS class and the noise disclosure are where these two near-twins actually differ.
On a pair this alike, none of the cards is about weight or capacity; the differences hide in the ratings. The UPS class is the one with consequences: ≤20ms on the RIVER 3 230 and ≤30ms on the RIVER 2, both ceilings rather than measurements. Behind a router or modem, either does the job. Behind a desktop with unsaved work, the RIVER 2's class is the one that may reboot it. The difference the cards don't flag sits on the same desk: a 100W USB-C port on the RIVER 3 230 against 60W, which a bigger laptop actually feels.
Read the noise card carefully. EcoFlow publishes 30 dB for the RIVER 3 230 as a maximum, reached when it charges or discharges hard, so a light load runs below it; the RIVER 2 publishes nothing. The comparison coverage we have says the RIVER 2 runs louder under loadA1A3, which is a reviewer's account, not a meter reading. The warranty card is a wash at 5 years apiece.
Runtime: Will It Power Your Gear?
Selected because: The RIVER 2's extra 26Wh is its only hardware lead, and this is where it shows.
The RIVER 2's extra battery shrinks to 22Wh once the flat 85% derate applies: 218 usable against 196. On the 100Wh afternoon load the engine models, that's the difference between finishing with 118Wh in reserve and finishing with 96. Both are leftovers you'd struggle to notice.
Everything else that governs runtime is shared: the same 300W inverter, the same 110W solar ceiling, the same 3,000-cycle rating. Refilling either from empty at that 110W ceiling takes a bit over two hours of strong sun by the arithmetic alone, before real panel losses stretch it. Capacity is not a reason to swap one for the other.
Your Life, Your Pick
Selected because: Six of seven scenarios overrun both units, which settles what either one is for.
Six of seven scenarios come back neither, and most aren't close: a camping weekend wants 2,100Wh, roughly ten times what either delivers. The row worth reading is CPAP Overnight, where the RIVER 2 covers about 68% of the night and the RIVER 3 230 about 61%. Both run out before morning. The RIVER 2 just runs out later.
Afternoon Off-Grid is the job these were built for, and both pass: 46% used on the RIVER 2, 51% on the RIVER 3 230. Tailgate fails on a different spec entirely, a 400W peak that beats both 300W inverters before capacity gets a vote. Read the table as a size verdict on both units, not a contest between them.
Growth Path
Selected because: Neither expands and neither is sold new by EcoFlow, so growing means choosing a successor.
Neither expands, which was fine when these were sold as sealed grab-and-go boxes. Now there's no new unit to grow into on either side, so the growth question becomes which successor. The RIVER 2 240 is the RIVER 2 with a slightly smaller battery. The RIVER 3 PLUS is a size up and takes an extra battery.
That makes the obvious upgrade from a RIVER 2 a sideways step: its like-for-like replacement holds less, not more. If you've outgrown either of these, the path runs through the RIVER 3 PLUS or a larger station altogether.

Conclusion
October 11, 2026
Verdict: the RIVER 3 230
Both units have left EcoFlow's store, so there is no live unit here to recommend and the honest call is a tie. As hardware they barely separate: the same 300W inverter, 7.8 lbs, 110W solar input and 3,000-cycle rating, split only by the RIVER 2's extra 26Wh against the RIVER 3 230's 100W USB-C port and ≤20ms UPS class. If you own either, keep it; nothing on the other side is worth a swap. If you're buying new, EcoFlow's like-for-like small unit is the RIVER 2 240, and the RIVER 3 platform now starts a size up with the RIVER 3 PLUS.

Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
See the full weight table and data sourcing on our methodology page →Class ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews — no buyer opinions feed it. We score every station on size-independent quality (value, output, portability, endurance, ports, warranty, and more), then percentile-rank it against the other units in its capacity class, so a class-leading compact unit and a class-leading whole-home unit can both earn 5★. Here, RIVER 2 rates 3.9/5 (38th percentile of 25 Personal-class units), and RIVER 3 230 rates 4.4/5 (63rd percentile of 25 Personal-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
UPS Transfer: ≤20ms vs ≤30ms
Both list a UPS mode, and both figures are ceilings, not measurements. The RIVER 3 230's ≤20ms class is fine on paper for routers, modems and most electronics. The RIVER 2's ≤30ms class is one many desktop power supplies won't ride through, so if it's guarding a computer with unsaved work, plan for a possible reboot.
Warranty: Same Five Years
Both carry a 5-year term on our record, so cover doesn't separate them. Neither is stocked by EcoFlow any more, so if you're buying leftover or marketplace stock, confirm the seller passes on the maker's warranty before you count on it.
RIVER 2: No Published Noise Figure
EcoFlow publishes 30 dB for the RIVER 3 230 and nothing for the RIVER 2. Read that 30 dB the right way round: EcoFlow's RIVER figure is a ceiling, reached when the unit charges or discharges hard, so a light bedside load sits below it. The RIVER 2's blank isn't proof it's louder; it's a spec you can't hold it to.

Lifetime energy delivered
│ warranty ends · Reaching the cycle rating means ~80% capacity remains — degraded, not dead.
Analyst note
Neither is sold new any more, so there is no price left to work a cost per kWh from, and what either costs you now depends on the used market. The hardware comparison still holds: over its rated life the RIVER 2 delivers about 768 kWh and the RIVER 3 230 about 690 kWh. One thing to know reading the table: both carry the same 3,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.

Analyst note
Neither of these is sold new any more, so there is no growth path to buy into on either side. If you already own one: the RIVER 2 is fixed at 256Wh and the RIVER 3 230 is fixed at 230Wh. As a purchase decision, expandability isn't the question here.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 2
The research on the RIVER 2 is mostly comparative, drawn from review sites and EcoFlow's own materials rather than owner forumsA0. What it agrees on: the RIVER 2 shares the RIVER 3's core platform, with LiFePO4 cells, a 300W inverter and roughly 60-minute fast charging, and it earned its reputation as a proven budget unitA2.
The knock is refinement. Its spec sheet carries no noise rating, and one comparison review cites owner reports that it runs noticeably louder under load than the RIVER 3A1. The same site calls it a reasonable indoor buy that lacks the newer unit's waterproofing, faster UPS and quieter runningA3.
“Shares the same core platform as the RIVER 3 — 300W output, LiFePO4 chemistry, and roughly 60-minute fast charging — and remains a popular, proven budget small-format unit.”

Field data on this exact variant is thin: most coverage is of the RIVER 3 line broadly, so what follows is line-level and only directional for a 230Wh unitB0. The line's headline is quiet, under 30 dB by EcoFlow's figure, which reviewers single out as one of the biggest steps up from the RIVER 2B1.
Reviewers also credit the RIVER 3 with IP54 waterproofing, a faster UPS transfer and a 2x runtime mode the RIVER 2 lacksB2, and recommended it over the RIVER 2 for camping, van life and home UPS useB3. That verdict was written while both were on sale; today it compares two units EcoFlow no longer stocksB0.

Who Should Buy Which
Buy the RIVER 2 if you…
- →You already own a RIVER 2 and use it for phones and laptops: keep it. The RIVER 3 230 holds less and matches it on output, weight and solar input, so there's nothing worth trading toward.
- →You want the RIVER 2's exact layout new from EcoFlow: that's the RIVER 2 240, the same unit with a slightly smaller battery.
Buy the RIVER 3 230 if you…
- →You own a RIVER 3 230 and charge a laptop that wants more than 60W, or guard a computer through outages: keep it. The 100W USB-C port and the ≤20ms UPS class are the two things here the RIVER 2 can't match.
- →You want the RIVER 3 platform new from EcoFlow and can carry a bigger box: the RIVER 3 PLUS is the smallest RIVER 3 still sold.
If neither fits
If you're shopping for CPAP nights, blackouts or a campsite, close this tab. Even the RIVER 2 covers only about two-thirds of a CPAP night, and an 8-hour blackout wants 1,645Wh, more than seven times what it can deliver. Look at stations several sizes up. And if all you charge is phones, a power bank does that job without carrying an AC inverter around.
The Bottom Line
Call it a tie, because neither can be bought from EcoFlow any more. As spec sheets they're near-twins: same inverter, same weight, same sockets. The RIVER 2's extra battery buys a later shortfall on a CPAP night, and the RIVER 3 230's faster USB-C and tighter UPS class only matter at a desk.
If you own either, keep it; nothing on the other side earns a swap. If you're buying new, pick between successors: the RIVER 2 240 for this exact size, the RIVER 3 PLUS if you'll carry a bigger box for the newer platform.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Are the EcoFlow RIVER 2 and RIVER 3 230 discontinued?
Yes. Both have left EcoFlow's own store. EcoFlow now sells the RIVER 2 240 in the RIVER 2's place, the same unit with a slightly smaller battery, and the smallest RIVER 3 it still stocks is the RIVER 3 PLUS. The RIVER 3 230 survives only as marketplace listings we don't track.
What's the difference between the RIVER 2 and the RIVER 3 230?
Less than the names suggest. Both put out 300W with a 600W surge, weigh 7.8 lbs, take 110W of solar and are rated for 3,000 cycles. The RIVER 2 holds 256Wh to the RIVER 3 230's 230Wh; the RIVER 3 230 has a 100W USB-C port to the RIVER 2's 60W, a ≤20ms UPS rating to ≤30ms, and a published noise figure the RIVER 2 lacks.
Can the RIVER 2 or RIVER 3 230 run a CPAP all night?
No. The CPAP night we model takes 320Wh, and after the flat 85% derate the RIVER 2 delivers about 218Wh and the RIVER 3 230 about 196Wh. That covers roughly 68% and 61% of the night. For full nights you need a much larger station.
Should I replace my RIVER 2 with a RIVER 3 230?
Not for capacity: you'd give up 26Wh and gain nothing in output, weight or solar input. The case for the swap is the 100W USB-C port and the tighter UPS rating. Since the RIVER 3 230 has also left EcoFlow's store, a swap now means the RIVER 3 PLUS, a bigger unit, rather than a like-for-like replacement.
Which is quieter, the RIVER 2 or the RIVER 3 230?
Probably the RIVER 3 230, though no meter on this page settles it. EcoFlow publishes 30 dB for it as a ceiling at high charge or discharge rates and publishes nothing for the RIVER 2. Comparison reviews say the RIVER 2 runs louder under load.
