EcoFlow stopped selling the RIVER 3 Max Plus Wireless in August, so one side of this comparison carries no price and no buy button. That changes the question rather than ending it. You are not choosing between two units any more. You are asking whether the Anker SOLIX S2000 is enough on its own, and what a RIVER you already own is still good for.

It is enough for most of what people buy a 2kWh box to do. The S2000 holds 2,010Wh to the RIVER's 1,196Wh, runs a 1,500W inverter to the RIVER's 600W, and takes 400W of solar to the RIVER's 200W, which means the bigger pack is also the faster one to refill. Eight hours of blackout essentials needs 1,645Wh, and only one of these two gets there.

The RIVER was a good small station and its specs are still true: 20.8 lbs you lift with one hand, a UPS switch rated no worse than 10ms, and a 3,000-cycle pack good for 8.2 years of daily use. None of that is a recommendation now. It is context for the reader who owns one, and a reason to look at the DELTA 3 Classic if the RIVER's size was the appeal.

02

What the Numbers Reveal

Each conclusion stated first — the numbers behind it on one line, the full analysis below.

F1

That moves the question rather than voiding the page. The live decision is now the S2000 against EcoFlow's DELTA 3 Classic, and this page can only settle half of it. What it can settle is whether the S2000 clears your loads on its own, and on the eight-hour essentials profile it does: 1,708Wh usable against 1,645Wh needed, by 63Wh.

EcoFlow retired the RIVER 3 Max Plus Wireless in August; the page shows no price and no buy button for itEcoFlow's named replacement for it is the DELTA 3 Classicthe SOLIX S2000 is a current model that launched in June 2026B0

Why it mattersIf you are shopping, stop comparing these two and check the S2000 against your own load list. If you own the RIVER, read on for what it still covers.

F2

continuous output

Every loss on this page is a capacity loss, not a power loss. The eight-hour blackout is the clean case: the RIVER holds that 150W load without complaint and still stops 628Wh early, because 1,017Wh usable cannot cover 1,645Wh. The fix a stranded RIVER needs is watt-hours, and the S2000 ships with 2,010Wh of them.

the largest peak any scenario on this page asks for is 400W, at the tailgatethe RIVER is 600W rated with a 1,200W peak; the S2000 is 1,500W rated with a 3,000W peak, each exactly double its own ratingthe RIVER starts and sustains the load in all six profilesone review names the RIVER's ceiling plainly: no high-power hairdryer, no microwaveA4

Why it mattersAnyone whose small station dies overnight needs a bigger battery, not a bigger inverter. The exception is the load list the 600W ceiling refuses outright, and there the S2000's 1,500W is the answer to that too.

F3

solar input

In an outage that runs past one night you are refilling every day, and the smaller pack buys back none of that time. It just leaves you less to spend before the next sunrise. The S2000 covers the 1,645Wh essentials night and then starts the next morning an hour ahead on the refill.

the S2000 takes up to 400W of solar into a 2,009.6Wh packthe RIVER takes up to 200W into a 1,196Wh pack

Why it mattersIf you are buying for multi-day outages rather than one bad evening, the solar input column deserves more of your attention than the weight column.

F4

rated cycles

Cover is identical at five years each, so the warranty is not what separates these two. The pack clock is. At daily cycling the S2000's 27.4 years against the RIVER's 8.2 puts both well past the term, but only one of them is a decade-scale purchase. Neither pack dies at the limit either; capacity settles to roughly 80% and carries on.

10,000 rated cycles on a 2,009.6Wh pack3,000 rated cycles on a 1,196Wh packboth records carry a five-year warranty

Why it mattersIf you want one box you buy once, the S2000 is the one with the long clock. The RIVER's 8.2 years of daily use is a fine run, just a different kind of purchase.

The specific dimensions that decide these two units — everything else is a tie.

Your Life, Your Pick

Selected because: Six load profiles, and every one of them turns on capacity rather than inverter size, including the eight-hour blackout at 1,645Wh that only the S2000 finishes.

Two rows go to nobody, and they are the ones to read first. A 2,100Wh camping weekend leaves the S2000 392Wh short, which is 81% of the list and in practice means the lights and the fridge but not everything you wrote down. Van Life Daily asks 4,685Wh, and that is not a near miss. It is a different class of product.

The row that decides the page is the eight-hour blackout at 1,645Wh. The S2000 finishes with 63Wh left of its 1,708Wh usable, which is a pass and a thin one, so plan on eight hours rather than nine. The RIVER covers about 62% of that night and stops. Everywhere else the two simply trade margin: the 910Wh remote workday leaves the RIVER 107Wh of slack against the S2000's 798Wh, which is the difference between finishing and not having to think about it. One caveat on every usable figure above, including the 1,708Wh and the 1,017Wh: they come off a flat 85% derate the site applies to every unit, not a measurement of either of these.

Lifetime Value

Selected because: 10,000 rated cycles on the larger pack against 3,000 on the smaller one, which is 20,096 kWh of lifetime energy against 3,588.

One of these packs is still working when the other has been replaced three times over, and the arithmetic is unusually blunt: 27.4 years of daily cycling against 8.2. That comes from 10,000 cycles at 2,010Wh against 3,000 at 1,196Wh, which is 20,096 kWh of lifetime energy against 3,588. The S2000 wins on both terms at once, and multiplying them is what makes the gap lopsided rather than close.

Neither pack dies when the cycle count runs out. Capacity settles to roughly 80% of original and keeps going, which here widens the gap instead of closing it: 80% of 2,010Wh is about 1,608Wh, still more than the RIVER holds new.

What the Specs Don't Tell You

Selected because: Three cards fire here, and the one worth your time is the S2000's fixed 2,010Wh ceiling.

rated cycles

The honest catch belongs to our pick. The S2000 is sealed, and 2,010Wh is all it will ever be, so if your needs are visibly growing that is the one reason on this page to pause. The RIVER's answer to that is an expansion port, and it reads better than it works: the base unit starts 814Wh below the S2000, so the first expansion battery spends most of itself catching up to what the S2000 already includes, and it only pulls ahead past 2,010Wh.

The warranty card is a real tie at five years each, which leaves cycle life to do the separating. It does, and it does it by a factor no port count or app rating reaches.

Portability & Form Factor

Selected because: 20.8 lbs against 35.7 is the only column the RIVER wins, and it is worth knowing what the S2000 asks of you at the trunk.

weight

20.8 lbs is a one-hand lift out of a trunk. 35.7 lbs is a two-hand, set-it-down-before-the-stairs lift, and reviewers at two separate outlets independently landed on the carry handle as the weak point of an otherwise solid buildB7B8. That is a genuine cost of the bigger pack and there is no point pretending otherwise.

It is also the only column the RIVER wins, and the one you cannot spend. Weigh the extra 15 lbs against what it buys: 2,010Wh, five AC sockets to three, and double the solar input. If that 15 lbs is honestly the deciding factor, EcoFlow's named replacement for the RIVER is the DELTA 3 Classic, and it is worth checking what that one weighs before assuming it carries the same.

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 covers this scenario's 2,100Wh: the RIVER 3 MAX PLUS WIRELESS comes up 1,083Wh short (about 48% covered), the SOLIX S2000 392Wh (81%). Treat this as partial cover — enough for the essentials in it, not the whole list.

8-Hour Blackout

Keep the essentials running through a night without power

SOLIX S2000

Eight hours of essentials is 1,645Wh, and the S2000 finishes it with 63Wh of its 1,708Wh usable left. That is a pass, not a cushion, so treat it as an eight-hour unit and keep a solar plan for hour nine. The RIVER holds the 150W load without complaint and still covers only about 62% of the night, which is roughly five hours of an eight-hour outage. Nothing about the inverter decides this row. Capacity does, alone.

SCN-03 · 8 hours · needs 320Wh

CPAP Overnight

Sleep therapy without interruption — the #1 medical use case

Either unit

A CPAP draws about 40W, so the night is 320Wh and both units treat that as a rounding error rather than a load. Which means capacity is not the deciding factor here and neither is the noise column, where the two published figures are not the same kind of number. What decides it is that only one of the two is still sold. If you already own the RIVER, it will carry your machine roughly three nights on a charge, from 1,017Wh usable against 320Wh a night, and there is no reason to replace it until it stops doing that.

SOLIX S2000

The SOLIX S2000 clears the workday at 53% used, banking 798Wh — late work, extra calls, or a second laptop charge without arithmetic. The RIVER 3 MAX PLUS WIRELESS at 90% also finishes, with 107Wh of slack for the unplanned.

Game day power for the crew

SOLIX S2000

Game day is a 670Wh afternoon with a 400W peak, and both units start it and hold it without effort. The S2000 just walks away at 39% used against 66%, which is the margin for the second cooler nobody planned for. The RIVER's 20.8 lbs against 35.7 is the one figure that favours it here, and also the one you cannot act on, because there is nothing to order. Budget two hands and a flat surface for the S2000 and the afternoon looks the same.

Neither unit covers this scenario's 4,685Wh: the RIVER 3 MAX PLUS WIRELESS comes up 3,668Wh short (about 22% covered), the SOLIX S2000 2,977Wh (36%). 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 19, 2026

Verdict: the SOLIX S2000, on Power Score margin

Take the Anker SOLIX S2000. EcoFlow discontinued the RIVER 3 Max Plus Wireless in August, so there is exactly one unit on this page you can order, and it is also the stronger one on the axes that decide a blackout: 2,010Wh against 1,196Wh, a 1,500W inverter against 600W, and 400W of solar input against 200W to refill it. The eight-hour essentials profile makes it concrete. The S2000 finishes that night with 63Wh left of its 1,708Wh usable while the RIVER stops 628Wh short. The RIVER's one genuine win is the 20.8 lb carry against 35.7, and that is not a win you can act on at a checkout. If you already own one, keep it and read on for what it still does well. If you were cross-shopping EcoFlow, the replacement EcoFlow names is the DELTA 3 Classic.

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 WIRELESS rates 3.6/5 (15th percentile of 27 Everyday-class units), and SOLIX S2000 rates 5.0/5 (99th percentile of 26 Large-class units).

Test Notes & Caveats

Hidden gotchas and advantages we spotted that you won't find on the product page.

[NOTE]

The S2000's Ceiling Is the Ceiling

2,010Wh is everything the S2000 will ever be. There is no expansion port, so what you buy is what you own, and that is a real limitation worth naming before anyone else does. The catch is that the alternative is worse rather than better: the RIVER starts 814Wh lower at 1,196Wh, so its first expansion battery spends most of itself buying back capacity the S2000 ships with, and the pairing only pulls ahead past 2,010Wh. It is also a growth path whose base unit EcoFlow no longer sells.

[NOTE]

Five Years Each, and Only One Still in the Catalogue

Both records carry a five-year term, so coverage length is not a tiebreaker. What differs is what stands behind it. The S2000 is a current model inside a range Anker is still selling and servicing, while the RIVER 3 Max Plus Wireless has left EcoFlow's line-up, and EcoFlow offers no parts or service once a warranty period ends. Five years on a discontinued unit is still five real years of cover. Just do not plan on year six.

[NOTE]

Battery Lifespan in Real Years

The SOLIX S2000 is rated for 10,000 cycles vs 3,000. In real life: at daily use, that's 27.4 vs 8.2 years. At weekend use (twice a week), it's 96 vs 29 years. One caution reading years across different sizes: a cycle is 2,010Wh on the SOLIX S2000 and 1,196Wh on the RIVER 3 MAX PLUS WIRELESS, so count lifetime energy — roughly 20,096 kWh against 3,588 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.

Analyst note

The RIVER 3 MAX PLUS WIRELESS is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the SOLIX S2000 works out at $0.03/kWh over its rated life. If you already own the RIVER 3 MAX PLUS WIRELESS, the hardware comparison still holds: over its rated life the RIVER 3 MAX PLUS WIRELESS delivers about 3,588 kWh and the SOLIX S2000 about 20,096 kWh.

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.

Support

US-based support. Historically known for incredible no-hassle replacements, but recent reports describe AI-driven support agents giving generic responses and complex return logistics for heavy units (hazmat shipping). The Anker brand reputation is still strong, but SOLIX-specific support quality is trending down.

Community

Moderate — active Reddit (r/Anker, r/AnkerSOLIXCommunity) and growing. Benefits from Anker's massive consumer electronics brand awareness.

App experience

Rated 4.5/5 iOS (~1,100 ratings) · 4.3/5 Android

Unique strength

Parent brand trust from Anker's consumer electronics dominance. InfiniPower technology for long cycle life. Strong $/Wh value in the mid-size and larger units — the S2000, F2600 and C1000 are among the better buys per watt-hour in the catalog.

Worth knowing

Support quality appears to be declining from its historically excellent level. Firmware updates have removed features without warning. Expansion ecosystem is smaller than EcoFlow's.

All Anker power stations tested →

Analyst note

EcoFlow runs the deepest catalogue in portable power and the fastest release cadence, which is the same reason this unit is gone: it got replaced rather than neglected. Anker's SOLIX range is smaller and its support desk has been trending the wrong way from a historically excellent level, but the S2000 is a current model in a line still being sold and serviced, and Anker's per-watt-hour pricing in this size class is among the better value in the catalogue. Neither brand profile changes the verdict here, since only one of these two can be ordered. If you are cross-shopping EcoFlow rather than settling this pair, the DELTA 3 Classic is the unit EcoFlow points RIVER 3 Max Plus Wireless buyers toward.

Growth path

RIVER 3 MAX PLUS WIRELESS

EXPANDABLE

Supports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 1,196Wh.

Accepts up to 200W of solar. Limited to a single portable panel.

Adequate ports for most setups, but heavy users may want a power strip.

Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.

SOLIX S2000

FIXED CAPACITY

Fixed at 2,010Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.

Accepts up to 400W of solar. Suitable for a 1-2 panel setup.

Adequate ports for most setups, but heavy users may want a power strip.

RIVER 3 MAX PLUS WIRELESSSOLIX S2000

Analyst note

Growth only counts if you can still buy in, and the RIVER 3 MAX PLUS WIRELESS is no longer sold (EcoFlow points owners to the DELTA 3 Classic). That leaves the SOLIX S2000: it is sealed at 2,010Wh, so buy the size that covers you now. The RIVER 3 MAX PLUS WIRELESS's expandability still matters if you already own one, but it isn't a reason to pick it over the SOLIX S2000.

EcoFlow RIVER 3 MAX PLUS WIRELESS

There is no mature field record for this exact configuration. Our research turned up no owner threads and no six-month reports for the Max Plus Wireless specifically, only press-review coverage, and several of those entries describe sibling RIVER 3 models rather than this oneA0A7A8A9. Read everything below as early-adopter evidence, not a settled record.

What exists is consistent as far as it goes. One review clocked it at about 2.3 hours from empty to full on mains, quick for the capacityA1. EcoFlow publishes the RIVER series' 30dB figure as a maximum reached at high wattage rather than a best-case floor, and reviewers describe the unit as genuinely quiet to sleep besideA2A3. The UPS switch, rated no worse than 10ms, gets called out for keeping devices from dropping outA5. And one review states the ceiling plainly: no high-power hairdryer, no microwaveA4.

“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 S2000

The S2000's ledger is young but unusually hands-on. Two independent outlets ran real tests rather than repeating the press kit, though the unit only launched in June 2026, so nothing here speaks to longevityB0. Both found the fans stay off at idle and spin up only under heavy load or the fastest charging modeB1B2, and both measured standby draw separately: about 2W with everything disabled across a 10-hour hold, about 6W with the AC ports enabled but unusedB3B4. For a unit that sits charged in a closet waiting for an outage, that is the number that matters most.

On performance, a recharge from a standard 20-amp household circuit hit 80% in roughly 1.2 hours and full in about 1.7B5, a simulated outage passed without connected office gear noticing the switchoverB9B10, and one test ran a fridge plus kitchen gadgets for over 60 hours on a chargeB12. The complaints are small and specific: two reviewers independently wanted a proper one-hand carry handleB7B8, and one noted a warm-electronics smell in a closed office through the first several hours that faded after a day with no safety concernB6. The app gets described as the more polished one in the categoryB11.

“Fans only spin up under real load or fast charging, and at idle the unit is silent.”

Who Should Buy Which

Buy the RIVER 3 MAX PLUS WIRELESS if you…

  • →You already own one, and it stays on the nightstand and the desk. A CPAP at 40W is 320Wh a night against 1,017Wh usable, so roughly three nights before it needs a wall, and the 910Wh remote workday still finishes with 107Wh in hand.
  • →You are eyeing leftover retailer stock and want to know what you are taking on. EcoFlow has retired the model, offers no parts or service out of warranty, and the 3,000-cycle pack is the shorter clock of the two. The replacement EcoFlow names is the DELTA 3 Classic.

Buy the SOLIX S2000 if you…

  • →The eight-hour blackout is why you are here. 1,708Wh usable covers a 1,645Wh essentials night with 63Wh left, the 1,500W inverter starts everything on that list, and the UPS switch takes the router across without a flicker.
  • →You want one box you buy once. 10,000 rated cycles is 27.4 years of daily use, and at the limit the pack settles to about 80% rather than quitting.
  • →You run a fridge through summer storms and want margin instead of arithmetic. One test held a fridge plus kitchen gadgets for over 60 hours on a chargeB12.
  • →You charge from panels. 400W in means a full refill is about five hours of strong sun, from 2,009.6Wh divided by 400W.

If neither fits

If your day looks like the van-life row, 4,685Wh every single day, neither of these is the answer and no expansion gets you there. That is a station sized well past 4,685Wh with a real array behind it, or a proper wired DC system. The same goes if your camping list is the full 2,100Wh one: the S2000 covers 81% of it, which means something on the list does not run. And if the appeal was the RIVER's 20.8 lb one-hand carry rather than its output, close this tab and look at EcoFlow's DELTA 3 Classic or another small station. The S2000 is the better unit. It is not a small one.

08

The Bottom Line

Buy the Anker SOLIX S2000, at $700. The retirement makes the call for you, but the specs would have made it anyway. It is the unit that finishes the eight-hour blackout, the one whose 10,000-cycle pack still holds more at 80% than the RIVER holds new, and the one that comes back from the sun an hour sooner despite carrying 814Wh more.

The RIVER's 20.8 lbs was a genuinely nice thing about it, and it still is if you own one. It is just not something you can put in a cart any more. If the small, light box was the whole appeal, go look at the DELTA 3 Classic. Otherwise pick the S2000 up with both hands and stop thinking about it.

Frequently Asked Questions

Answers drawn from the spec record and cited owner research.

Can I still buy the EcoFlow RIVER 3 Max Plus Wireless?

No. EcoFlow retired it in August, which is why this page shows no price and no buy button on that side. The replacement EcoFlow names is the DELTA 3 Classic. Retailer stock can linger for a while after a discontinuation, so you may still find one listed, but you would be buying a model the maker has moved on from and offers no parts or service for outside the warranty period.

Will the Anker SOLIX S2000 get me through an 8-hour outage?

Yes, with 63Wh to spare. The eight-hour essentials profile draws 1,645Wh and the S2000 has 1,708Wh usable after the flat 85% derate applied to every unit on the site. Its 1,500W inverter and 3,000W peak start everything in that profile, whose largest single draw is 150W. Treat it as a pass rather than a comfortable one: plan eight hours, not twelve.

Is the SOLIX S2000 quiet enough to sleep next to for CPAP?

A CPAP is roughly 40W, so a night is 320Wh and the S2000 spends 19% of itself on it. In testing the fans stayed off at idle and spun up only under heavy load or the fastest charging mode, neither of which describes a 40W draw. Both records list 30dB, but those figures are published on different terms, EcoFlow's RIVER number being a maximum reached at high wattage, so do not read the match as a measured tie.

Does the SOLIX S2000 have a 12V car socket?

Our record does not carry that field for the S2000 at all, which is a blank rather than a zero, so we will not tell you either way. Check Anker's own spec sheet if a 12V output is a requirement. For contrast, the RIVER's record does list one, plus three USB-A ports to the S2000's one. The S2000 leads on AC sockets, five to three, and on USB-C, two to one, both units at 100W.

Is the RIVER's expandability a reason to hunt down leftover stock?

No. It starts at 1,196Wh, which is 814Wh below the S2000, so a first expansion battery mostly buys back capacity the S2000 already includes, and the setup only pulls ahead if you would grow past 2,010Wh. Expansion is also only a feature while you can still buy the base unit, and largely you cannot.
