EcoFlow RIVER 3 MAX PLUS vs Anker SOLIX C2000 Gen 2
Four of the six loads on this page don't fit inside 858Wh, which makes this a sizing question rather than a matchup, and the smaller answer is the one EcoFlow has stopped selling.

No longer sold
EcoFlow no longer sells the RIVER 3 Max Plus. At this size the closest unit EcoFlow still sells is the RIVER 2 Pro — 768Wh with a stronger 800W inverter, typically for less money. If you'd rather step up in capacity, the DELTA 3 Classic (1,024Wh, 1,800W) is the move.

Spec deltas
The SOLIX C2000 Gen 2 carries 2,048Wh to the RIVER 3 MAX PLUS's 858Wh, which after the flat 85% usable derate applied to every unit here is 1,741Wh against 729Wh. Run the six loads on this page through those two figures and the small box stops in four of them. It isn't a worse unit. It's a unit for a shorter list.
One fact to get out of the way before the specs: EcoFlow no longer sells the RIVER 3 MAX PLUS. That doesn't make the comparison academic, since clearance stock moves for months and plenty of people already own one, but it does change what this page is for. Choosing today with money in hand, you're choosing the Anker or something EcoFlow still makes. Holding a RIVER already, you want the runtime section and can skip the rest.
The money runs the opposite way from the sticker. At $359 against $1,000 the RIVER is the cheaper battery per watt-hour, and across the cycle life these two packs are rated for it's the more expensive one to use. Purchase price and cost of energy point in different directions here, and that's the part of this comparison that catches people out.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
Divide each price by its own lifetime energy and the cheap box is the expensive one: $0.14 per lifetime kilowatt-hour for the RIVER, $0.12 for the SOLIX. You're not paying close to three times the price for three times the battery; you're paying it for three times the battery at a slightly better rate than the small one charges.
RIVER 3 MAX PLUS: $359 for 858WhSOLIX C2000 Gen 2: $1,000 for 2,048WhRated cycle minimums: 3,000 for the RIVER, 4,000 for the SOLIX
Why it mattersIf $359 felt like the safe amount to spend, note that the unit with the bigger number on it is the one selling energy cheaper.
solar input
The RIVER's speed story is a mains storyA1, and mains is precisely what's missing in the outage people buy these for. Four times the panel input covers nearly two and a half times the capacity, so on a sunny day the SOLIX is topped up before lunch while the RIVER is still working on a battery a third the size.
RIVER 3 MAX PLUS: 200W maximum solar input, 858Wh to fillSOLIX C2000 Gen 2: 800W maximum solar input, 2,048Wh to fillOne reviewer clocked the RIVER at roughly 2.3 hours empty to full from a wall socketA1
Why it mattersBuying for grid failure rather than campsites means weighting input wattage as heavily as capacity, and on solar the RIVER is a trickle by comparison.
continuous output
That gap never surfaces in the scenario table, because 400W is comfortably inside 600W. It surfaces the first time you plug in a fridge, a sump pump or a compressor-driven cooler, where 1,200W is the entire envelope and the headroom inside it is described as resistive-load territoryA7A4.
RIVER 3 MAX PLUS: 600W continuous with a 1,200W published peak, a 2x ratioSOLIX C2000 Gen 2: 2,400W continuous with a 4,000W published peak, a 1.7x ratioReviewers describe the RIVER's extended output above its rating as aimed at resistive loads like heaters and hair dryers rather than sensitive electronicsA7, and say it won't run a microwave or a high-power hairdryerA4The heaviest switch-on any of the six scenarios asks for is 400W
Why it mattersIf anything on your list has a motor in it, read the surge ceiling, not the scenario rows.
weight
So the RIVER wins the only portability question a trunk actually asks, and the tailgate row shows the price of winning it: it gets through game day on 92% of usable capacity, which means the easy carry and the empty reserve are the same fact. Add one more load and you've spent the margin.
RIVER 3 MAX PLUS: 20.8 lbs holding 858WhSOLIX C2000 Gen 2: 41.7 lbs holding 2,048WhTailgate Party uses 92% of the RIVER's usable capacity and 38% of the SOLIX's
Why it mattersBuy the RIVER for the carry only if your load list is as small as the carry; otherwise that's lightness chosen over finishing.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: 858Wh against 2,048Wh settles four of the six loads on this page before any other spec gets a vote.
continuous output
Usable energy is the only runtime figure worth arguing about, and the flat 85% derate applied to every unit here puts it at 729Wh for the RIVER and 1,741Wh for the SOLIX. Nothing about that ratio is close, and nothing about it is a defect: the RIVER was built to be a box one arm can carry, and 858Wh is what fits in a box that size.
The trouble is where ordinary loads land. A remote workday wants 910Wh, which the RIVER misses by 181Wh, close enough to sting. An eight-hour blackout wants 1,645Wh, which it misses by 916Wh, more than its entire usable capacity. Loads have a habit of landing just past 729Wh, and when they do, 858Wh stops being a choice you're making and becomes a wall you're hitting.
Your Life, Your Pick
Selected because: The SOLIX finishes four of these six loads, the RIVER two, and two are beyond both units; the pattern tells you more than any single row.
Two of the six rows are losses for both units, and they're the honest kind. Weekend camping wants 2,100Wh and van life daily wants 4,685Wh; the SOLIX covers 83% and 37% of those, the RIVER 35% and 16%. Partial cover is genuinely useful, in that it runs the essentials on the list rather than the list, but neither of these is the unit for a week in a van.
Where they separate is the middle. The SOLIX takes the blackout and the workday outright, while the RIVER's two passes are the two smallest loads on the board: a CPAP overnight, which both clear several times over, and a tailgate it finishes on 92% of usable capacity. Read the rows you'd actually live rather than the tally.
Lifetime Value
Selected because: The cheaper unit to buy is the more expensive one to use, at $0.14 per lifetime kilowatt-hour against $0.12.
cost / lifetime kWh
Cost per lifetime kilowatt-hour is the only money figure on this page that accounts for the pack wearing out, and it's the one that reverses the sticker. Both packs are rated for at least their cycle number, both carry up to five years of coverage, so this is apples to apples: the more expensive unit delivers energy more cheaply.
None of which makes $1,000 the right amount for you to spend. It makes $359 the wrong number to shop by, because it buys under a third of the lifetime energy. If the budget really is $359, the useful move is a smaller current-model station, not the largest discontinued one you can find.
Portability & Form Factor
Selected because: 20.8 lbs against 41.7 is the one axis the smaller unit wins outright, and for some buyers it's the only axis that counts.
weight
Twice the weight for nearly two and a half times the energy is a fine trade on paper and an irrelevant one on a footpath. 41.7 lbs goes into a trunk with two hands and comes out the same way; 20.8 lbs goes over a shoulder while you're carrying something else, which is why the RIVER is the one that reaches the far campsite and the SOLIX is the one that ends up living beside the breaker panel.
The rest of the portability column is a wash. Both are rated to switch over in no worse than 10ms, so either will sit under a desk as a UPS, and the SOLIX's 140W USB-C against the RIVER's 100W only matters if you charge a laptop from it daily. Weight is the tiebreak, and it's the one spec where the small unit is simply right.
Brand Trust
Selected because: One of these two is out of production and EcoFlow offers no parts or service out of warranty, which turns the brand column into a practical question rather than a preference.
The brand column has a practical edge on this pairing that it usually doesn't. EcoFlow has stopped selling the RIVER 3 MAX PLUS, and EcoFlow offers no parts or service once a unit is out of warranty. Inside the five years you're covered the same as the Anker. After that, a discontinued unit with no parts channel is a unit you own until it stops. Against that, EcoFlow runs the largest ecosystem and the largest community in portable power, and a big forum is what a manual turns into once the maker moves on.
Anker's flaw pairs badly with its weight. SOLIX support quality is trending down from the no-hassle standard Anker's consumer electronics business built, toward AI-driven first responses and hazmat logistics on heavy returns: the hardest unit here to lift is also the one you'd least enjoy shipping back. Whichever you choose, buying through a retailer with a real returns desk is worth more than either company's support page.

Scenario verdicts
We ran the math on six real-world scenarios. Here's which unit survives your actual life.
SCN-01 · 2 nights · needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Neither unit finishes the weekend's 2,100Wh, so the row is really about how far short. The SOLIX covers 83% of it, close enough that trimming one load or catching a few hours of sun gets you home. The RIVER covers 35%. Treat the big one as a weekend that needs rationing and the small one as a night or two with a short list.

LOAD Phone Charger 15W×6h · LED Lights 40W×8h · Box Fan 75W×14h · CPAP Machine 40W×16h
SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
SOLIX C2000 Gen 2
The SOLIX takes this, and the margin is the interesting part: 1,741Wh of usable energy against a 1,645Wh load leaves 96Wh, a pass with nothing behind it. Plan on one outage rather than two unless sun or mains shows up in between. The RIVER isn't in this conversation. It's 916Wh short, more than its entire usable capacity, so it covers about 44% of the evening and then needs a recharge it can't get at 200W in the dark.
Battery budget usedlower = more headroom
LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Both clear this one and it isn't close to close. A CPAP is about 40W for eight hours, so the RIVER ends the night with 409Wh of usable energy untouched and the SOLIX with 1,421Wh. Capacity has stopped being the question. Both print 30dB, but those numbers are published to different conventions, and EcoFlow states its RIVER figure as a maximum hit at high charge or discharge, so the spec sheet can't break the tie either. What can: nights before a recharge, roughly two on the RIVER against five on the SOLIX, and the 20.8 lbs versus 41.7 lbs you have to get into the bedroom in the first place.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
SOLIX C2000 Gen 2
Eighty percent of a workday is not a workday. The RIVER covers 729Wh of the 910Wh this asks and stops 181Wh short, which is the last stretch of the afternoon, exactly when you'd notice. The SOLIX finishes with 831Wh spare, most of another day's worth, so the question of whether the sun shows up tomorrow becomes tomorrow's question.

LOAD Laptop 60W×8h · External Monitor 30W×8h · Router + Modem 20W×8h · Phone Charger 15W×2h
SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
SOLIX C2000 Gen 2
Both get through game day, and the SOLIX does it on 38% of its usable capacity against the RIVER's 92%. That 92% is the number to sit with, because it means the RIVER arrives at the end with 59Wh in reserve, which is not a second anything. Game day is a light load, so what your arms will remember is 20.8 lbs against 41.7 from the trunk to the tailgate. Just don't add to the list you brought.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit covers this scenario's 4,685Wh: the RIVER 3 MAX PLUS comes up 3,956Wh short (about 16% covered), the SOLIX C2000 Gen 2 2,944Wh (37%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Conclusion
September 13, 2026
Verdict: the SOLIX C2000 Gen 2, on Power Score margin
Buy the SOLIX C2000 Gen 2. It finishes four of the six loads here to the RIVER 3 MAX PLUS's two, it delivers energy over its rated life more cheaply ($0.12 per lifetime kilowatt-hour against $0.14) despite costing close to three times as much up front, and it's the only one of the two still in production. The RIVER only makes sense on a short list: a CPAP, a laptop, phones, lights. At those loads it clears a night with 409Wh of usable capacity untouched, so if you already own one there's nothing here that says replace it, and at a genuine clearance price it's 20.8 lbs that does small jobs well. Paying full price for a discontinued station is the one thing not to do, and EcoFlow offers no parts or service once a unit is out of warranty.

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 MAX PLUS rates 4.9/5 (95th percentile of 20 Compact-class units), and SOLIX C2000 Gen 2 rates 4.1/5 (48th percentile of 26 Large-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.
The ratio flatters the smaller inverter
The RIVER holds the better ratio above its own rating, 2x against 1.7x, and that's the less useful of the two numbers here. A motor's inrush is an absolute wattage, not a percentage of whatever inverter it's plugged into, so what decides whether a compressor starts is the ceiling: 4,000W on the SOLIX against 1,200W on the RIVER. The RIVER's virtue is the flip side of the same coin, in that at steady state it runs further below its own limit.
Five years each, and one asterisk
Coverage is the same on both, up to five years, so it breaks nothing, and the per-dollar version of the stat is just the price gap wearing a warranty costume. The asterisk isn't in the terms, it's in what comes after them: EcoFlow offers no parts or service out of warranty, which reads differently on a unit the maker has stopped selling than on one still in production. Register whichever you buy, and on the RIVER, know what year six looks like.
Battery Lifespan in Real Years
The SOLIX C2000 Gen 2 is rated for 4,000 cycles vs 3,000. In real life: at daily use, that's 11 vs 8.2 years. At weekend use (twice a week), it's 38 vs 29 years. One caution reading years across different sizes: a cycle is 2,048Wh on the SOLIX C2000 Gen 2 and 858Wh on the RIVER 3 MAX PLUS, so count lifetime energy — roughly 8,192 kWh against 2,574 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.

Worth knowing
Firmware updates have removed features without warning, and the expansion catalogue is smaller than EcoFlow's. Neither is a reason to walk away, but buy it for what it does today.
Analyst note
Neither brand column decides this pairing, because only one of these two units is still being made. EcoFlow wins on ecosystem breadth and community size; Anker wins on parent-brand track record and on value per watt-hour in the mid-size and larger classes. The honest read: buy from the channel with the best returns policy, and weight production status ahead of brand preference.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 3 MAX PLUS
Field evidence on this exact unit is thin, and the shape of it matters: our research turned up no owner threads naming the RIVER 3 MAX PLUS, only short hands-on reviews, several of which were really about the smaller RIVER 3 or RIVER 3 PlusA0. Read what follows as first impressions rather than six months of ownership.
What's there agrees on the basics. Reviewers consistently describe the Max Plus as the base station bundled with the larger EB600 expansion battery, adding up to the 858Wh in the tableA2A9A6. One reviewer clocked it at roughly 2.3 hours empty to full from mains, which is quick for the capacityA1, and the sub-10ms UPS switching gets singled out as a standout across the RIVER 3 Plus and Max familyA3. One called it a strong middle ground for weekend off-grid and wild parkingA5, which is about the right size of claim. On limits they're equally clear: no microwave, no high-power hairdryerA4, and the extended output above 600W belongs to resistive loads rather than a desktop PCA7.
“The RIVER 3 Max Plus (Wireless) can go from empty to full from mains in around 2.3 hours, which is very quick given its capacity.”

Anker SOLIX C2000 Gen 2
Coverage of the C2000 Gen 2 is broader and uniformly positive, though it's review-desk coverage; no six-month owner reports came back this passB0. Fan behaviour is the most useful thing in it. Reviewers describe fans that never rise above a backgrounded whirr, only occasionally reaching about 35 dB at a meter under high loadB1, which is the opposite of the complaint 2 kWh units usually attract.
Past noise, the recurring notes are plug-and-play simplicity with no firmware wrangling or voltage odditiesB2, app monitoring over Bluetooth or Wi-Fi that reviewers found genuinely useful rather than decorativeB3, and a Gen 2 that shed a large amount of weight against the original C2000B5, worth knowing if you're weighing it up against an older review's figure. One reviewer rates it among the most attractive 2 kWh stations on the marketB4.
“Even at full power it's far quieter than any other powerful Anker station tested — the fans never rise above a subdued, easily-backgrounded whirr, working largely silently and only occasionally reaching a pleasantly quiet ~35 dB at 1 m under high load.”

“Even at full power it's far quieter than any other powerful Anker station tested — the fans never rise above a subdued, easily-backgrounded whirr, working largely silently and only occasionally reaching a pleasantly quiet ~35 dB at 1 m under high load.”

“Substantially lighter than its predecessor — the Gen 2 shed a large amount of weight versus the original C2000, making it notably easier to carry for its capacity.”

Who Should Buy Which
Buy the RIVER 3 MAX PLUS if you…
- →You already own one. At CPAP-and-phones loads it clears the night with 409Wh of usable capacity still in the tank, and nothing on this page is a reason to replace a working unit.
- →You found real clearance stock and your list is short: a CPAP, a laptop, phones, lights, a fan. At full price on a discontinued station there's no case; at a genuine discount it's 20.8 lbs that runs small things for a weekend.
- →You care more about the walk than the reserve. If the unit has to travel further than the tailgate while you're carrying a cooler in the other hand, the SOLIX isn't making that trip.

Buy the SOLIX C2000 Gen 2 if you…
- →You want one box to cover an evening without power. 1,741Wh of usable energy takes the whole 1,645Wh blackout load with 96Wh left, which is a pass and not a relaxed one, so plan it as one outage rather than two.
- →You work from a truck, a cabin or a site office. A 910Wh workday leaves 831Wh spare, so you finish the day and still have the evening.
- →You want panels doing the recharging. 800W of solar input is four times the RIVER's ceiling, and it's the spec that turns a multi-day outage from a problem into a routine.
- →Anything with a compressor in it. A 4,000W surge ceiling starts things a 1,200W ceiling has to argue with.
If neither fits
Full-time van life. That load wants 4,685Wh and the bigger of these two covers 37% of it, so you're looking at the wrong shelf: shop stations rated several times this capacity with high solar input, or a proper house-battery build. And if $359 is a hard ceiling rather than a preference, don't chase discontinued stock to hit it. EcoFlow's RIVER 2 Pro is the current unit in that slot, with the DELTA 3 Classic as the step up if your list is longer than the budget suggests.
The Bottom Line
Take the SOLIX C2000 Gen 2. It finishes four of these six loads to the RIVER's two, it refills from panels in less absolute time despite holding nearly two and a half times the energy, and it sells its lifetime energy more cheaply than the box costing about a third as much. The RIVER 3 MAX PLUS isn't beaten so much as out-sized, and EcoFlow having stopped selling it settles the part of the argument the specs left open.
What the RIVER still wins is the walk from the car, and on a list that stops at a CPAP, a laptop and some phones that isn't nothing. At a real clearance price it's a sensible box, and if you own one, keep using it. Paying full price for a station out of production isn't sensible: EcoFlow's RIVER 2 Pro is where that slot went, with the DELTA 3 Classic as the step up. For everyone else the sizing question answers itself. Buy the one that finishes the night.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow RIVER 3 MAX PLUS discontinued?
Yes. EcoFlow no longer sells it, so what's left is retailer and clearance stock. That doesn't make it a bad station, but it does mean only considering it at a real discount, and knowing that EcoFlow offers no parts or service once a unit is out of warranty. EcoFlow's RIVER 2 Pro is the current station in that size bracket.
Can the RIVER 3 MAX PLUS run a refrigerator?
Treat that as a maybe rather than a yes. Its inverter runs 600W continuous with a 1,200W published peak, and reviewers describe the headroom above the rating as intended for resistive loads like heaters rather than motors. A compressor's switch-on spike is an absolute wattage, not a percentage of your inverter's rating, which is why the SOLIX C2000 Gen 2's 4,000W peak removes the question entirely.
How many nights will each one run a CPAP?
A CPAP is about 40W for eight hours, so 320Wh a night. Against usable capacity that's about two nights on the RIVER's 729Wh and about five on the SOLIX's 1,741Wh. Both are rated at 30dB, but makers publish that figure to different conventions, so don't buy on it: EcoFlow states its RIVER number as a maximum reached at high charge or discharge, and a 40W load is nowhere near high.
Which one is cheaper to own?
The SOLIX C2000 Gen 2, despite costing close to three times as much. Its bigger pack and 4,000-cycle rating spread the purchase price over about three times the lifetime energy, working out at $0.12 per lifetime kilowatt-hour against $0.14. Cheaper to buy and cheaper to own are different questions here, and they have different answers.
Do I actually need 2,048Wh, or is 858Wh enough?
Add your loads in watt-hours and compare them against usable energy rather than nameplate: 729Wh for the RIVER, 1,741Wh for the SOLIX. A CPAP night is 320Wh and a tailgate 670Wh, both inside the small unit. A remote workday is 910Wh and an eight-hour blackout 1,645Wh, both outside it. The line sits at 729Wh, and real loads have a habit of landing just past it.
