EcoFlow RIVER 3 230 vs BLUETTI EB3A
Neither of these is still for sale. The EB3A, the later of the two to go, is a strong campsite battery and a shaky bedside one, and the live comparison is now the RIVER 3 PLUS against the Elite 30 V2.

Spec deltas
EcoFlow has stopped selling the RIVER 3 230. Its own store dropped it, and the RIVER 3 PLUS is now the smallest RIVER 3 it carries. The BLUETTI EB3A has since followed it out. BLUETTI's store has had it sold out since July 2026, and the Elite 30 V2 is the unit that replaced it. So this page shows no price on either side. It stays up for owners of either and for anyone who finds one in leftover stock.
The EB3A isn't a consolation prize for the jobs it suits. The EB3A doubles the RIVER's continuous output, 600W against 300W, carries 38Wh more, and takes 200W of solar against 110W, so the bigger tank also refills faster from a panel. The cost of all that is 2.3 lb: 10.1 against 7.8, still a one-hand carry.
The catch sits exactly where the RIVER 3 230 was strongest. Owners consistently report the EB3A throwing false 'overload' shutdowns in UPS mode at light loads, including a CPAP user who lost power two to three hours into the night at a 40W drawB5B7B8. If bedside standby is the job, the comparison that matters is the RIVER 3 PLUS against the Elite 30 V2, the two units you can still buy, and we compare them on their own page.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
The fault lives in UPS mode, not in the battery. One camper running a CPAP straight off a full charge got about six hoursB17. So the EB3A works as a camping CPAP battery you recharge by day, but not as an unattended backup behind the bed, and firmware hasn't reliably fixed thatB6B9. The reason the RIVER 3 230 used to win this matchup went off sale with it.
EB3A UPS switchover rated ≤30ms; RIVER 3 230 rated ≤20msOwners report false overload shutdowns in UPS mode at 40 to 60W loadsB5B7CPAP Overnight needs 320Wh; the EB3A delivers 228Wh usable, about 71% of it
Why it mattersCPAP and router owners shopping for standby should compare the RIVER 3 PLUS, the Elite 30 V2 or a larger station rather than hunt down a leftover EB3A.
continuous output
But 228Wh usable at 400W lasts about half an hour (228 ÷ 400 ≈ 0.6 h). The doubled output buys short bursts of a mid-size appliance, not an afternoon of one.
EB3A: 600W continuous, 1,200W surgeRIVER 3 230: 300W continuous, 600W surgeTailgate Party peak is 400W; the RIVER 3 230 starts it but can't hold it, the EB3A holds it
Why it mattersA RIVER 3 230 owner who keeps hitting the 300W ceiling would get a real fix from an EB3A, if they can find one; anyone who doesn't is buying output they'll never use.
solar input
An afternoon off-grid uses under half the EB3A, so a panel at lunch puts it back to full before the next outing. With a panel that can actually feed 200W, its 268Wh behaves like a battery that resets every sunny day, which is how one tester ran it through camping trips and five days of van lifeB16.
EB3A: 200W solar input, 268Wh capacityRIVER 3 230: 110W solar input, 230Wh capacityAfternoon Off-Grid needs 100Wh; the EB3A finishes at 44% used
Why it mattersCampers who own a panel get more from the EB3A's 200W input than from its extra 38Wh.
rated cycles
What doesn't disappear is the warranty, 5 years against 2. For a RIVER 3 230 owner that's the strongest reason to keep it rather than trade into the EB3A. For an EB3A buyer, 2 years is the cover, backed by support owners in the UPS threads describe as unhelpfulB9B10.
RIVER 3 230: rated 3,000+ cycles, 5-year warranty, 690 lifetime kWhEB3A: rated 2,500+ cycles, 2-year warranty, 670 lifetime kWh
Why it mattersRIVER 3 230 owners should hold on unless they need more than 300W; EB3A owners are on BLUETTI's 2-year term, so keep the receipt.
The specific dimensions that decide these two units — everything else is a tie.
What the Specs Don't Tell You
Selected because: The EB3A's ≤30ms switchover, its fan, and its 2-year term against the RIVER's 5 decide which jobs it suits.
rated cycles
A backup that cries 'overload' at 40W is the worst kind of failure, because nobody plans for it. The EB3A's ≤30ms switchover rating already sits outside what many desktop PCs ride through. The light-load shutdowns owners describe are worseB5B7B8, since they hit the router-and-CPAP loads people assume a small unit can't possibly overload.
Noise points the same way. BLUETTI publishes 50dB as the EB3A's best case and EcoFlow publishes 30dB as the RIVER's ceiling under heavy load, so the figures aren't the same measurement, but owners settle it: the EB3A's fan cycles on even when idle and fully charged on ACB3B4. The warranty card, 5 years against 2, now speaks to owners rather than shoppers. It's the best argument for keeping a RIVER 3 230 you already have.
Your Life, Your Pick
Selected because: Six of seven scenarios come back 'neither'; the one both pass is the 100Wh afternoon these units are built for.
Six 'neither' rows out of seven is the most useful result on this page. These are 230Wh and 268Wh boxes, and a weekend camp, a blackout, a van day and a remote workday all ask for several times what either delivers. The 8-hour blackout alone needs more than seven times the EB3A's 228Wh usable (1,645 ÷ 228).
The row both pass is the 100Wh afternoon off-grid, where the RIVER finishes at 51% used and the EB3A at 44%. CPAP Overnight is the near miss that matters: the EB3A covers about 71% of the modeled night, so even before the UPS question it isn't a full-night CPAP battery on this profile. Buy it for afternoons and you'll never see its limits.
Portability & Form Factor
Selected because: The retired RIVER is 2.3 lb lighter, which matters mostly to owners weighing a trade.
weight
2.3 lb separates them, 7.8 against 10.1. Both are one-hand carries; the RIVER disappears into a daypack, the EB3A rides on the passenger seat.
Per pound, the RIVER packs a little more, about 29.5Wh against the EB3A's 26.5 (230 ÷ 7.8 and 268 ÷ 10.1). But neither can be ordered new now, so the weight gap is a question for owners deciding whether a trade into leftover stock is worth it, and for them the answer is usually no.
Brand Trust
Selected because: With both units off their makers' stores, support is an owners' question on both sides.
The support question splits with the retirement. If you own a RIVER 3 230, EcoFlow's US phone and chat line is who honors its 5-year term, and EcoFlow offers no parts or service once that runs out. If you own an EB3A, or pick one up from leftover stock, you're dealing with support the brand profile flags as the category's most inconsistent: email-first, slowed by time zones.
Owners in the UPS threads describe exactly that, a firmware update offered as the fix and then a shrugB9, or an app ticket that never got an answerB10. With BLUETTI no longer selling the unit, buying direct is off the table, so keep the receipt from wherever yours came from. That 2-year term is the cover you have.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Neither unit
Neither carries the modeled 320Wh night. The EB3A gets about 71% of the way and the RIVER 3 230 about 61%, so both run dry before morning on this profile. Plan on a shorter night, a lower-draw machine, or a bigger station.

Runtime model
Runtime = (rated capacity × 0.85 inverter efficiency) ÷ device wattage. Solar recharge estimates assume panels deliver 70% of rated output. Cold weather, battery age, and stacked loads reduce real-world results.
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 3 230 rates 4.4/5 (63rd percentile of 25 Personal-class units), and EB3A rates 3.9/5 (33rd percentile of 25 Personal-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
EB3A: 50dB, Published as Its Best Case
BLUETTI rates the EB3A at 50dB as its best case, about as loud as moderate rainfall. EcoFlow rates the RIVER 3 230 at 30dB as the most it reaches under heavy charging or discharging. A floor and a ceiling aren't the same kind of number, so don't subtract them. Taken at their makers' word, though, the EB3A's quietest sits above the RIVER's loudest, and around 45dB is where sleep starts to suffer.
UPS Switchover: ≤20ms vs ≤30ms
Both are rated ceilings, not lab results. The RIVER 3 230's ≤20ms is the class most electronics ride through, but it left EcoFlow's store with the unit. The EB3A's ≤30ms is a transfer many desktop PCs won't survive, so plan on reboots if a computer with unsaved work is what you're protecting.
Warranty: 5 Years vs 2
The RIVER 3 230 carries 5 years of cover; the EB3A carries 2 on our record. For a RIVER owner, that term is the best reason not to trade it in. For an EB3A owner, 2 years is the cover you get, and BLUETTI no longer sells the unit, so keep the receipt from wherever it came from.

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 3 230 delivers about 690 kWh and the EB3A about 670 kWh.
Brand trust
EcoFlow
Ecosystem
Largest in portable power — 12-15 models across DELTA Pro, DELTA 3, and RIVER 3 series, plus solar panels and smart home panels
Support
US-based phone/email/chat support (1-800-368-8604). Experiences are polarized — many report hassle-free prepaid-label replacements, but others report long waits and refurbished units sent for new claims. Pro tip: buying from Costco or Amazon gives you a stronger return safety net.
Community
Largest community in the space — Reddit r/Ecoflow_community (~31K members), multiple Facebook groups, and an official community forum
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
Fastest-charging technology (X-Stream), deepest product ecosystem, and most active innovation cadence. At the top of the range sit two whole-home paths: the TITAN line, one 5 kWh unit that grows to 30 kWh, and the DELTA Pro Ultra platform, which stacks batteries and inverters further — flagship paths, not line-wide features.
Worth knowing
Tested subscription paywalls for advanced app features in early 2025 before community backlash paused the plan. No parts or service offered out of warranty.
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.
Support
The most inconsistent support in the space. Heavily email-based with China timezone delays. Some users get smooth, efficient service; others report weeks of troubleshooting runarounds, being offered discounts on new units instead of repairs, and confusing third-party purchase claim processes. Buying direct from Bluetti's website tends to produce better support outcomes.
Community
Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.
App experience
Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.
Unique strength
Among the best capacity-to-price ratios available — several Elite and Apex units are the lowest $/Wh in the catalog. Widest product diversity including industry-firsts like sodium-ion cold-weather units and dual solar+alternator vehicle hubs. LFP across the rest of the range, though rated cycle life spans 2,500 (EB3A) to 6,000, and it varies WITHIN the Elite range rather than tracking it — the Elite 300 and Elite 200 V2 are rated 6,000 while the Elite 30 V2, Elite 10 Mini, Elite 320 and Elite 400 are rated 3,000+ and the Elite 100 V2 4,000+, so check the specific model. Dual-voltage (120V/240V) in flagships.
Worth knowing
Customer support inconsistency is the #1 risk factor. Older/discontinued units may become unrepairable — no spare parts policy for some models. Some reports of erratic communication from support agents.
Analyst note
With the RIVER 3 230 gone from EcoFlow's store, the brand column splits by reader. RIVER owners deal with EcoFlow's US phone and chat support for the rest of their 5-year term, with no parts or service after it ends. EB3A owners get BLUETTI's email-first support, the least consistent in the category, and with the unit gone from BLUETTI's store there is no direct purchase to fall back on.
Growth path
RIVER 3 230
FIXED CAPACITYFixed at 230Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 110W of solar. Limited to a single portable panel.
Limited ports. You'll likely need a power strip or splitter.
EB3A
FIXED CAPACITYFixed at 268Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 200W of solar. Limited to a single portable panel.
Limited ports. You'll likely need a power strip or splitter.
Realistic full solar rechargeat 70% of rated panel output — see methodology
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 3 230 is fixed at 230Wh and the EB3A is fixed at 268Wh. 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 3 230
Field data on this exact 230Wh variant is thin: our research found coverage of the RIVER 3 line broadly, much of it about the standard RIVER 3A0. What carries over is the line's reputation for running under 30dB, IP54 sealing and a faster UPS switchover than the RIVER 2 it replacedA1A2, and reviewers named the RIVER 3 the better buy for camping, van life and home UPS duty where noise mattersA3. None of that is long-term ownership testimony, and with the unit gone from EcoFlow's store, little more is likely to arriveA0.
“The RIVER 3 operates under 30 dB — EcoFlow calls it 'whisper quiet,' quieter than a library — one of the most significant upgrades over the louder RIVER 2.”

BLUETTI EB3A
The EB3A's field record splits cleanly by job. As a portable, reviewers like it: one called it a well-polished product that crams a lot into a small packageB13, another took it through two camping trips, an 18-hour outage and five days of van life over 60 days and would buy it againB16, and a CPAP camper got about six hours from a full chargeB17. The complaints on that side are small: limited capacity, a clunky app, no port coversB14.
As a wall-plugged backup it's a different unit. Owners consistently report false 'overload' shutdowns in UPS mode at 40 to 60W, from a CPAP user who lost power two to three hours into the nightB7 to a poster who knew of two units that failed the same wayB8; firmware didn't fix it for them and in one case made it worseB6B9. Our research dates these reports from 2022 through 2024B0. A second, separate pattern is the fan: cycling on every 20 minutes or so even when fully charged on ACB3, buzzing before it startsB4, odd ramp-up and wobble noisesB1B2, and charging noise one reviewer likened to a power-tool battery chargerB12. One owner also noted interference with a nearby monitorB11, and one reviewer said its switchover isn't true UPS at allB15.
“Bluetti advertises the EB3A as "tiny but mighty," and I have to agree. They crammed a lot of ports and functionality into a very portable package... it seems to be a very well-polished product.”

“It's not perfect. The capacity is limited, the app is clunky, and there are no port covers.”

“No, the EB3A does not have true UPS functionality. There's a brief 1-2 second interruption when switching from grid power to battery during an outage.”

“After 60 days of testing—two camping trips, an 18-hour power outage, and five days of van life—would I buy the Bluetti EB3A again? Yes, without hesitation.”

“On a full charge, the BLUETTI EB3A powered my CPAP machine for approximately six hours... Charging the BLUETTI EB3A from a household outlet took just over four hours.”

Who Should Buy Which
Buy the RIVER 3 230 if you…
- →You already own a RIVER 3 230 and never need more than 300W: keep it. Its 5-year warranty and ≤20ms switchover rating are reasons to stay put, and the EB3A's main advantage is output you aren't using.
- →You liked the RIVER 3 230's small format and want that from EcoFlow, new: EcoFlow now points buyers to the RIVER 3 PLUS, the smallest RIVER 3 it still sells.
Buy the EB3A if you…
- →You already own an EB3A, or found one in leftover stock, and you're packing for car camping or a day at the lake with a panel that can feed 200W, and you want something that runs a 400W load in short bursts and refills by lunch.
- →You own a RIVER 3 230 that keeps tripping at its 300W ceiling. The EB3A's 600W continuous fixes exactly that, if you can find one. The Elite 30 V2 is what BLUETTI sells in its place.
- →You want a camping CPAP battery you'll run straight off a full charge rather than plugged into the wall, and a night that may end around the six-hour mark one camper got is acceptableB17.
If neither fits
You're buying for blackouts or an always-on bedside backup. The modeled 8-hour outage needs 1,645Wh, more than seven times the 228Wh the EB3A actually delivers, and owners' light-load UPS shutdowns make it a poor unattended backupB5B7. Close this tab and look at a station several times this size with a pass-through mode you can trust.
The Bottom Line
Neither of these is for sale any more. For the campsite the EB3A was the stronger box anyway: twice the continuous output, faster solar refill, 38Wh more. A leftover EB3A still suits car camping, afternoons off-grid and short bursts of a few hundred watts, and the Elite 30 V2 is what BLUETTI sells in its place.
Don't buy it to sit plugged in behind a CPAP. The light-load overload pattern owners reportB5B7B9 lands exactly where the RIVER 3 230 was strongest, and that strength now lives in EcoFlow's RIVER 3 PLUS, not on this page. If the job is a tent, an EB3A you already own does it. If it's a nightstand, keep shopping, starting with the RIVER 3 PLUS against the Elite 30 V2.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow RIVER 3 230 discontinued?
Yes. EcoFlow's own store no longer carries it. The RIVER 3 PLUS is the smallest RIVER 3 EcoFlow still sells, and it's the unit to compare against the EB3A if you want to stay with EcoFlow.
Can the BLUETTI EB3A run a CPAP all night?
Not on the night we model. A 320Wh CPAP night is more than the 228Wh the EB3A delivers after losses, so it covers about 71%, and one camper got about six hours from a full charge. Run it straight off the battery rather than plugged in as a pass-through backup, the mode where owners report overload shutdowns at a 40W draw.
Is the BLUETTI EB3A a good UPS?
Not for anything you can't afford to lose. Its switchover is rated ≤30ms, a transfer many desktop PCs won't ride through, and owners consistently report false overload shutdowns at light loads in UPS mode that firmware updates didn't fix. Treat it as a battery you unplug and carry, and use a dedicated UPS or a larger station for always-on backup.
Is the BLUETTI EB3A loud?
Louder than a bedroom wants, by owners' accounts. They consistently report the fan cycling on every 20 minutes or so even when fully charged on AC, with buzzing or ramping noises around it. BLUETTI publishes 50dB as its best case.
Should I replace my RIVER 3 230 with an EB3A?
Only if you keep hitting its 300W limit, and only if you can find one, since BLUETTI no longer sells the EB3A either. It doubles continuous output to 600W and adds 38Wh, but your RIVER keeps its 5-year warranty, its ≤20ms switchover rating and 2.3 lb less to carry. If 300W covers what you plug in, the trade buys you nothing you'll use.
