Head-to-head test
EcoFlow RIVER 3 vs BLUETTI EB3A
EcoFlow has stopped selling the RIVER 3, so the EB3A wins by being the one you can still buy. It earns the win with twice the output, but it's a battery to run things from, not a pass-through UPS to forget about beside the bed.

Spec deltas
EcoFlow has dropped the base RIVER 3 from its store, and its product page now forwards elsewhere. That leaves this comparison with one unit you can buy new, the BLUETTI EB3A, and one you can only own already or find as leftover stock. EcoFlow names the RIVER 3 PLUS as the smallest RIVER 3 it still sells.
The specs still matter, because they tell you what you're giving up or gaining. The EB3A holds 23Wh more (268Wh to 245), pushes twice the continuous power (600W to 300W), and takes nearly double the solar input (200W to 110W), for 2.3 lbs more in the bag (10.1 to 7.8). The RIVER 3's real advantages were a 5-year warranty against the EB3A's 2, a 3,000-cycle rating against 2,500, and a faster-rated UPS transfer.
So the EB3A is the pick, with one warning label attached. As a battery you plug things into, it does more than the RIVER 3 did. As an always-plugged-in UPS guarding a CPAP or a PC, its field record is the weakest part of this page.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
That makes output, not the 23Wh capacity gap, the spec that changes what you can actually plug in. Anything drawing between 300W and 600W is a hard no on the RIVER 3 and a routine job on the EB3A, which only has to worry about running out of watt-hours, not watts.
EB3A: 600W continuous, 1,200W surgeRIVER 3: 300W continuous, 600W surgeTailgate Party scenario peaks at 400W: the RIVER 3 can start it but not hold it; the EB3A holds it
Why it mattersAnyone who wants to run a single real appliance for a short stretch, rather than just charge phones and laptops, should take the EB3A without a second thought.
The failure lives in UPS mode, the pass-through setup where the wall feeds the unit and the unit feeds the machine. Run from a charged battery instead and one tester got about six hours of CPAP from a full chargeB17, which squares with the 228Wh usable covering about 71% of the modeled 320Wh night.
EB3A UPS transfer rated no worse than 30ms; RIVER 3 no worse than 20msCPAP Overnight scenario: 40W peak, 320Wh needed; EB3A has 228Wh usable after the 85% derateOwners report false 'overload' shutdowns in UPS mode at 40 to 60W loads, not fixed by firmwareB5B6B7B8B9
Why it mattersCPAP users can buy the EB3A to run the machine off-battery and plan to top up, but anyone who wants it permanently plugged in as a bedside UPS should look at EcoFlow's RIVER 3 PLUS instead.
solar input
Real panels rarely hit their rating, which widens the gap rather than closing it: a slow input loses more of a cloudy afternoon. Over a multi-day trip, the heavier unit is the one more likely to start each evening full.
EB3A: 10.1 lbs, 200W max solar input, 268WhRIVER 3: 7.8 lbs, 110W max solar input, 245Wh
Why it mattersCampers pairing a panel with a small station get more from the EB3A's solar input than they lose to its extra weight.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Only one of the seven modeled jobs fits inside either unit, so knowing which loads these can run matters more than any single spec.
Six of seven rows come back 'neither', and that's the most useful thing on the page. A modeled 8-hour blackout wants 1,645Wh; the EB3A has 228Wh usable after the derate. These are bag-sized batteries for phones, laptops, lights and one small appliance at a time, and the grid isn't something they replace.
The row that counts is the afternoon off-grid job, and both handle it with room to spare. Tailgate is the instructive miss: the RIVER 3 can't hold the 400W peak at all, while the EB3A holds it and simply runs out of energy, 442Wh short. Short of watt-hours is a problem you solve by running it for less time. Short of watts is a problem you can't solve at all.
What the Specs Don't Tell You
Selected because: The EB3A's ≤30ms UPS rating and its fan behavior are where the live pick needs the most care.
rated cycles
The UPS card is the one to read twice. Both transfer times are rated ceilings, ≤20ms for the RIVER 3 and ≤30ms for the EB3A, and a 30ms class is one many desktop power supplies won't ride through. Add the owner reports of light-load overload shutdowns in UPS modeB5B7B8 and the EB3A is a poor choice for protecting a computer with unsaved work.
The noise card needs a translation. EcoFlow publishes the RIVER 3's 30dB as a maximum under heavy charging or discharging; BLUETTI's 50dB is its best case. Those are opposite kinds of number, so the gap between them isn't a measurement. What the field says is plainer: owners describe the EB3A's fan cycling on every 20 minutes or so even when fully charged on AC, too loud for a bedroomB3B4.
Portability & Form Factor
Selected because: At 10.1 lbs against 7.8, the EB3A's extra 2.3 lbs is the price of twice the output and nearly double the solar input.
weight
Both are one-hand carries. The RIVER 3 at 7.8 lbs disappears into a tote bag; the EB3A at 10.1 lbs is the one you notice at the bottom of a backpack, but you won't need two hands for it.
What the extra 2.3 lbs pays for is the reason the EB3A wins: an inverter that holds 600W instead of 300W and a solar input that takes 200W instead of 110W. That's not dead weight. It's the part that does the work.
Brand Trust
Selected because: With a 2-year term on the EB3A, how BLUETTI handles a claim matters more than it would on a longer warranty.
BLUETTI's support is the least predictable in this category, heavily email-based and slowed by time zones, and the EB3A's record term is 2 years. On a unit with a documented UPS-mode fault, that's a short runway with an unreliable help desk at the end of it; buying direct from BLUETTI tends to produce better support outcomes.
EcoFlow's support is US-based with a phone line, but it offers no parts or service out of warranty, which is the clause that matters to anyone holding a RIVER 3 now that it's off the shelf.

Neither unit
Neither works, for two different reasons. The RIVER 3 can start the 400W peak on its 600W surge but its 300W continuous rating can't hold it. The EB3A holds it easily and then runs dry, 442Wh short of the 670Wh the afternoon needs. That's the bigger station's job.

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 rates 4.1/5 (50th 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.
Two Different Kinds of Decibel
EcoFlow publishes the RIVER 3's 30dB as a ceiling under heavy charge or discharge; BLUETTI publishes the EB3A's 50dB as its best case. One is a top and the other a floor, so don't read the gap as a measurement. If it's going beside your bed, assume the EB3A's fan will be audible.
Both Ceilings, Not Lab Results
The RIVER 3 is rated no worse than 20ms and the EB3A no worse than 30ms. A 30ms class is one many desktop power supplies won't ride through, so treat the EB3A as backup for routers, lights and phones rather than for a PC with unsaved work.
5 Years vs 2, and Only One Is On Sale
The RIVER 3 carries 5 years of cover against the EB3A's 2. That longer term belongs to people who already own a RIVER 3, since EcoFlow no longer sells it, and EcoFlow offers no parts or service once it ends. For the EB3A, the shorter term is a reason to buy direct from BLUETTI, which tends to produce better support outcomes.
Ownership Analysis
What happens after you buy — true cost of ownership, brand trust, and growth potential.
Lifetime value
Service lifeyears at one full cycle per day
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 delivers about 735 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
EcoFlow positions itself as a mid-to-premium brand with stronger support infrastructure, while BLUETTI competes on value. The question is whether the EcoFlow ecosystem and support premium is worth it for your use case.
Growth path
RIVER 3
FIXED CAPACITYFixed at 245Wh, 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 is fixed at 245Wh 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
What exists on the RIVER 3 is review and comparison coverage, mostly measuring it against the RIVER 2, rather than long-term owner reportsA0. That coverage is consistently warm: it credits the RIVER 3 with running under 30dB, the biggest single change from the louder RIVER 2A1, and with adding IP54 protection, a faster UPS switchover and a lighter build on the same platformA2A4. Reviewers recommended it for camping, van life and home UPS backup where noise mattersA3. None of that changes the fact that EcoFlow no longer sells it.
“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 in two. As a portable battery, testers like it: one called it a well-polished package that crams a lot of ports into a small boxB13, and a 60-day test through two camping trips, an 18-hour outage and five days of van life ended with 'yes, without hesitation'B16. Another tester ran a CPAP for about six hours on a full charge and recharged from the wall in just over four hoursB17. One reviewer's gripes were limited capacity, a clunky app and no port coversB14.
As a UPS, owners consistently report trouble. Light, steady loads of 40 to 60W in UPS mode trigger false overload shutdowns, reported across forums from 2022 to 2024B5B7B8; firmware updates didn't fix it for several owners and made it worse for oneB6B9, and one owner's support ticket went unansweredB10. One reviewer also saw a one-to-two-second gap on switchover, far longer than the ≤30ms ratingB15. Fan complaints run alongside: owners describe buzzing, ramping and a wobble even in silent modeB1B2B4, and a reviewer compared its charging noise to a power-tool battery chargerB12.
“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.”

Surge protection is only 150J, so he keeps it behind an older UPS's surge-only port.

Claims are weighted by how specific they are, whether the commenter owns the unit, and how many readers agreed. Comments that mention a product under a rival's review count for more, because the commenter had no reason to be there. This is what buyers report, not our test results — for measurements we ran ourselves, see the methodology.
Who Should Buy Which
Buy the RIVER 3 if you…
- →You already own a RIVER 3: keep it for phones, laptops and light loads under 300W, and lean on its 5-year term while it lasts, since EcoFlow offers no parts or service once it runs out.
- →You liked the RIVER 3 for its quiet and its UPS rating: EcoFlow points buyers to the RIVER 3 PLUS, so compare that against the EB3A rather than hunting down leftover RIVER 3 stock.
Buy the EB3A if you…
- →You want a small battery for the car or the campsite that can actually run a 400W appliance for a while, not just top up phones.
- →You're carrying a solar panel on a multi-day trip and want the 200W input to refill from a single good stretch of sun.
- →You need a CPAP backup you'll run off-battery during an outage, and you're fine charging it between nights rather than leaving it plugged in as a UPS.
If neither fits
If you're picturing the fridge, the furnace fan and the lights through a real outage, close this tab: the modeled 8-hour blackout needs 1,645Wh, about seven times the EB3A's 228Wh usable. Look at a station several times this size instead, and if the job is a silent always-on UPS for a desktop, at a dedicated UPS or a station with a faster-rated transfer.
The Bottom Line
The RIVER 3 has left EcoFlow's range, so the EB3A takes this by default, and it would have earned plenty of it anyway: twice the continuous output means a 400W load is a job it does rather than one it refuses, and nearly double the solar input keeps it fuller on a trip.
Use it as a battery, not a bedside UPS, and it's an easy recommendation. If silent, always-plugged-in standby is the whole point, check the RIVER 3 PLUS first. For everything else, get the EB3A.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow RIVER 3 discontinued?
Yes. EcoFlow has dropped the base RIVER 3 from its store, and the smallest RIVER 3 it still sells is the RIVER 3 PLUS. If you own a RIVER 3, its specs haven't changed; you just can't buy a new one from EcoFlow.
Can the BLUETTI EB3A run a CPAP all night?
It gets you most of a night, not all of one: 228Wh usable covers about 71% of our modeled 320Wh CPAP night. One tester got about six hours from a full charge. Run it from the battery rather than in UPS mode, where owners report false overload shutdowns at CPAP-sized loads.
Is the EB3A loud?
Louder than you'd want in a bedroom when it's plugged in. Owners report the fan cycling on every 20 minutes or so even when fully charged on AC, plus buzzing and ramping noises. BLUETTI's published 50dB is a best-case figure, so it isn't a fair number to set against EcoFlow's 30dB maximum for the RIVER 3.
Which has the better warranty, the RIVER 3 or the EB3A?
The RIVER 3, with 5 years against the EB3A's 2. That only helps someone who already owns a RIVER 3, since EcoFlow no longer sells it. On the EB3A, a 2-year term is a good reason to buy direct from BLUETTI, which tends to produce better support outcomes.
Can the EB3A run things the RIVER 3 couldn't?
Yes, anything drawing between 300W and 600W. The RIVER 3's 300W continuous rating can start a 400W load on its 600W surge but can't hold it; the EB3A runs it until the battery runs down.
