Head-to-head test
EcoFlow RIVER 2 Max vs Jackery Explorer 1000 Plus
EcoFlow has stopped selling the RIVER 2 Max, so the only live question left here is whether 512Wh was ever going to be enough — and across the six loads we model, it finishes one.

Spec deltas
The RIVER 2 Max has left EcoFlow's range. Its own store has the 512Wh unit sold out in every version and now lists the RIVER 2 Max 500 where it used to sit, which is why this page shows no price for it and no button to press. If you have a tab open on each of these, the comparison you are actually running is the Explorer 1000 Plus against a unit you would have to hunt for in leftover retailer stock.
That is a smaller loss than it sounds, because these two were never the same purchase. 512Wh and a 500W inverter on one side, 1,264Wh and 2,000W on the other. One is an overnight box, the other is a workday box, and they landed on the same page mostly because the two names keep turning up in the same search. Choosing between them was always choosing a size, not a brand.
The RIVER 2 Max was very good at the size it chose. 13.4 pounds is a one-hand carry, its LFP pack is rated for 3,000 cycles, and reviewers tended to lead with the weight rather than the capacityA1. None of that stopped being true when EcoFlow stopped selling it. But of the six load profiles we model, it finishes exactly one, and the Explorer 1000 Plus finishes three — so unless your entire requirement is what you can lift with one arm, the Jackery is the page's answer.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
So the retirement costs the reader much less than the Retired tab suggests. If your answer was 512Wh, that class still exists in EcoFlow's range under the successor's name and you should go look at it there. If your answer was more runtime, the discontinued unit was never the thing you were going to buy, and the Explorer 1000 Plus is unaffected by any of this.
EcoFlow's store has the 512Wh RIVER 2 Max sold out in every version and lists the RIVER 2 Max 500 in its placeRIVER 2 Max: 512Wh and a 500W inverter. Explorer 1000 Plus: 1,264Wh and a 2,000W inverterOf the six load profiles we model, the RIVER 2 Max finishes one and the Explorer 1000 Plus finishes three
Why it mattersAnyone who arrived undecided between these two has their decision made for them: uncertainty about size is itself the argument for the larger unit.
solar input
That kills the one argument that could have rescued the RIVER 2 Max on a multi-day trip — the idea that a small battery is at least a quick one to top up. It empties sooner and then makes you wait longer to be whole again. The Explorer 1000 Plus can go from empty to full inside a single good morning and still have the afternoon's sun spare.
RIVER 2 Max: 512Wh of battery behind a 220W maximum solar inputExplorer 1000 Plus: 1,264Wh of battery behind an 800W maximum solar inputThe remote-workday profile needs 910Wh; the RIVER 2 Max stops 475Wh short of it
Why it mattersIf you are off-grid past one night, read the solar input line before the capacity line. It is the spec that decides day two.
And the RIVER 2 Max's limit is not starting loads, it is finishing them. It holds every peak in all six profiles, the tailgate's included, and still walks away from that one 235Wh short. That means the usual small-unit workaround — be gentler with it — does not help. The loads were never too big. The day was too long.
RIVER 2 Max: 500W continuous, 1,000W surge, four AC outletsExplorer 1000 Plus: 2,000W continuous, 4,000W surge, three AC outletsThe tailgate profile peaks at 400W and needs 670Wh; the RIVER 2 Max sustains the peak but finishes 235Wh short
Why it mattersIf your reason for buying is that you run several things at once for hours, the socket count is decorative and the inverter and the battery are the purchase.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: The 435Wh vs 1,074Wh usable split, once both are derated, is what decides five of the six load profiles on this page.
continuous output
Nobody gets 512Wh out of a 512Wh battery. We apply a flat 85% derate to every unit on the site to cover conversion losses, which turns the RIVER 2 Max into 435Wh of real work and the Explorer 1000 Plus into 1,074Wh. It is a convention rather than a measurement of either box, but it is applied identically, so the 639Wh between them is honest — and that gap on its own is larger than everything the smaller unit holds.
The port strips tell the same story from the other end. The RIVER 2 Max has four AC outlets and 500W behind them; the Explorer 1000 Plus has one fewer socket and four times the inverter feeding it. That is the difference between planning which appliance goes on next and not thinking about it.
Your Life, Your Pick
Selected because: Of the six profiles, the RIVER 2 Max finishes one and the Explorer 1000 Plus finishes three — and how the smaller unit loses matters more than that it does.
Six profiles, one finish. The RIVER 2 Max covers the CPAP night and then stops: 475Wh short of the remote workday, 235Wh short of the tailgate, and nowhere near camping, blackouts or van life. The Explorer 1000 Plus takes three outright and comes closest on the three nobody wins.
Watch how the RIVER 2 Max loses, though, because it is not the way small units usually lose. It starts every peak in all six profiles and holds it. It simply runs out of energy while doing so. That is a capacity result, not an inverter result, and it means the unit is honest about what it is: several small things for an evening, done properly, and then it is done.
Portability & Form Factor
Selected because: 13.4 pounds against 32 is the one axis the RIVER 2 Max wins outright, and for some buyers it is the only axis.
weight
13.4 pounds against 32. That is the difference between carrying the thing in whichever hand is not holding the cooler and making a second trip to the car for it, and it is the only line on this page the RIVER 2 Max wins. It is also plainly what the unit was built to win — a 512Wh LFP pack light enough that reviews opened on the weight rather than the capacityA1.
The catch is that both halves of the trade are permanent. 32 pounds is a two-hands, straight-back lift out of a trunk, but you do it twice a trip and then you have two and a half times the battery on site for the rest of the weekend. If carry weight genuinely is your deciding spec, respect it — just do not satisfy it with a discontinued unit when the same maker has a current one on the shelf.
What the Specs Don't Tell You
Selected because: The UPS transfer ratings are ceilings rather than measurements, and the two makers publish their noise figures to opposite conventions.
rated cycles
The UPS ratings are where the class difference shows up in a single line. Both are ceilings rather than measured switches: no worse than 30ms on the RIVER 2 Max, no worse than 20ms on the Explorer 1000 Plus. The desktop power supplies that ride through the faster class are frequently the ones that reboot on the slower. If what you are protecting has unsaved work on it, that is the row to read, and neither figure is a lab result.
The noise ratings should be read once and then put down. EcoFlow publishes the RIVER series figure as a maximum reached under heavy charge or discharge; Jackery publishes a best case. Two numbers built that differently do not subtract, and the difference between them is not something you can count on hearing. If a bedroom is the destination, go find someone who has slept next to one.
Brand Trust
Selected because: One of these makers has just replaced the unit on this page; the other has the weakest app of the major brands and the widest retail counter.
The most useful brand fact here is the one that put the Retired tab on this page. EcoFlow runs the deepest catalogue in portable power and turns it over quickly, so models get succeeded rather than simply dropped, which is why there is a RIVER 2 Max 500 to point at. The cost of that cadence is on the back end: EcoFlow sells no parts and offers no service once a unit is out of warranty, and a unit that has already been replaced reaches that point sooner than one that has not.
Jackery's advantage is the opposite of cadence. It has the widest retail distribution of any of these brands, which matters chiefly because its app is the weakest of the major ones and because a Costco or Amazon return window is a more dependable remedy than a support queue. Buy it somewhere with a counter you can walk back to.

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 2 Max comes up 1,665Wh short (about 21% covered), the Explorer 1000 Plus 1,026Wh (51%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
Neither unit covers this list, and the honest framing is triage rather than backup. Eight hours of household essentials runs to 1,645Wh: the Explorer 1000 Plus gets about two-thirds of the way there, the RIVER 2 Max about a quarter. Pick the three things you would actually miss, let the rest go dark, and then think about how they get refilled — an outage that runs past sunset twice is decided by what you can put back in during daylight, not by what was in the battery when the lights went out.
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 of these clear a CPAP night without thinking about it, so the row is not about tonight. It is about the night after. The RIVER 2 Max finishes the 320Wh night with 115Wh of its 435Wh usable left, which is a phone charge rather than a second night; the Explorer 1000 Plus has 754Wh still in hand and gets three nights out of a full charge. If the reason you are buying is the storm that might last two days rather than the night that definitely will, that is the entire row, and it is why the Explorer 1000 Plus takes it.

Conclusion
September 19, 2026
Verdict: the Explorer 1000 Plus, on Power Score margin
Buy the Explorer 1000 Plus, and not merely by default. It is the one of these two still in its maker's range: EcoFlow's store has the RIVER 2 Max sold out in every version, with the RIVER 2 Max 500 standing in for it, so there is no price and no buy path for the older unit. It also wins the comparison that was already on the table. 1,264Wh against 512Wh, 2,000W continuous against 500W, 4,000 rated cycles against 3,000. The one thing it loses is the carry, at 32 pounds against 13.4, and that loss is real: if weight is the spec that decides your purchase, the Explorer 1000 Plus is the wrong unit for you and the right answer is EcoFlow's current small unit rather than a discontinued one.
Today the Explorer 1000 Plus is $619, $80 under its typical $699. The verdict weighs typical prices, not today's. Prices checked 16 days ago.

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 Max rates 3.7/5 (26th percentile of 20 Compact-class units), and Explorer 1000 Plus rates 4.6/5 (77th percentile of 27 Everyday-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.
RIVER 2 Max: 62dB Published
62dB is about as loud as a normal conversation. The Explorer 1000 Plus is rated 30dB, and the two are not the same kind of figure: the RIVER 2 Max's is a MAXIMUM under heavy charge and discharge, while the Explorer 1000 Plus's is its maker's best case — so the real gap can only be narrower than the numbers suggest, and may even run the other way. For most people, fan noise around 45dB and up is where sleep starts to suffer.
Expansion: The Least Relevant Thing Here
The Explorer 1000 Plus is the expandable one, and on this page it barely matters. Its 1,264Wh base is already 752Wh past the RIVER 2 Max's ceiling, so it wins the capacity argument before an expansion battery enters the room. Nor is sealed a flaw in a 512Wh unit: that is the complete form of the thing, sized and built to be carried. Expansion becomes a reason to buy only if you expect to outgrow 1,264Wh, which is a different question from the one this page answers.
UPS Switchover: ≤20ms vs ≤30ms
Both list a UPS mode, at different rated speeds. The Explorer 1000 Plus is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. The RIVER 2 Max is rated ≤30ms — a transfer this long is one many desktops will NOT ride through, so plan on reboots for sensitive gear. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Warranty: Same Term, Different Conditions
Both records carry five years, so coverage is not a tiebreaker. The difference is how you get there: Jackery's five is a conditional maximum that depends on registering the unit, so the box that arrives is not covered for the full term until you do. EcoFlow's five is stated plainly. One thing worth knowing before you chase a discontinued unit through a third-party seller: a warranty needs somebody to honor it, and EcoFlow sells no parts and offers no service once the term is up. Check the seller's own return window before you lean on either.
Battery Lifespan in Real Years
The Explorer 1000 Plus 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 1,264Wh on the Explorer 1000 Plus and 512Wh on the RIVER 2 Max, so count lifetime energy — roughly 5,056 kWh against 1,536 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 2 Max 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 Explorer 1000 Plus works out at $0.14/kWh over its rated life. If you already own the RIVER 2 Max, the hardware comparison still holds: over its rated life the RIVER 2 Max delivers about 1,536 kWh and the Explorer 1000 Plus about 5,056 kWh.

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
EcoFlow runs the deepest catalogue in portable power and moves through it quickly, which is why a model leaving the range reads as a replacement rather than an ending. The other side of that speed: once a unit is out of warranty, EcoFlow sells no parts and offers no service for it.

Support
US-based support but widely criticized. Reddit reports describe slow/dismissive responses, scripted AI agents, strict receipt requirements for warranty claims, and refurbished replacements for clearly defective units. Strongly recommended: buy from Costco or Amazon for return protection.
Community
Smallest community of the major brands — Reddit r/Jackery has ~2,000 members. YouTube presence is solid due to brand recognition.
App experience
Rated 2.3-3.3/5 iOS and Android — the weakest app experience of the major brands. Multiple confusing apps (Jackery app vs Jackery Home) and mandatory login even offline.
Unique strength
Highest brand recognition and widest retail distribution (Costco, Home Depot, Best Buy, Amazon). The "Toyota" of power stations — dependable, proven, wide availability. Innovative form factors like the Solar Gazebo and Solar Mars Bot.
Worth knowing
Jackery's reach is the reason to buy one, and its app is the reason to be patient with it — the weakest of the major brands, split across more than one app, with a mandatory login even when you are standing next to the unit. Costco, Home Depot, Best Buy and Amazon all stock it, so buy where the return window is real.
Analyst note
Two different safety nets. EcoFlow's is the catalogue: something current always replaces something retired, which is exactly what happened to the unit on the left of this page. Jackery's is the shelf: the widest retail distribution here, which is the remedy most owners end up using when something arrives wrong.

Analyst note
Growth only counts if you can still buy in, and the RIVER 2 Max is no longer sold (EcoFlow points owners to the RIVER 2 Max 500). That leaves the Explorer 1000 Plus: it starts at 1,264Wh and takes Jackery expansion batteries, so the ceiling moves if your needs do. The RIVER 2 Max's fixed 512Wh still matters if you already own one, but it isn't a reason to pick it over the Explorer 1000 Plus.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 2 Max
Coverage of the RIVER 2 Max is consistent and narrow: light, fast to charge, good app. Reviews led with the roughly 13-pound package and its LFP chemistry against same-size Li-Ion rivalsA1, and with X-Stream wall charging taking it from empty to full in about an hourA2 — which is worth noticing, because the recharge everyone praised happens at a wall socket, not on a panel. The EcoFlow app draws steady praise for monitoring and adjustable charge speed over Wi-Fi and BluetoothA3. One field account ran a telescope, a 65-inch TV, two laptops and phones through a four-hour event with power left overA4, which is exactly the shape of load this unit is good at.
What is missing from this ledger is any sustained complaint, and that is as likely to reflect a short, review-weighted coverage window as a flawless unitA0. Treat the praise as well-sourced and the silence as unproven.
“512Wh in a light package of about 13 lbs, lighter than some of its closest competitors that use Li-Ion chemistry.”

Jackery Explorer 1000 Plus
The Explorer 1000 Plus has the better evidence base of the two, including a six-month test across dozens of camping trips, two extended outages and daily home-office use, in which it ran every appliance inside its 2,000W rating and carried a fridge, lights, a laptop and a router simultaneously through a simulated outageB3. The 4,000-cycle rating and roughly 1.7-hour AC recharges hold up under testingB1, and expansion to about 5,000Wh across three added batteries is the feature reviewers reach for firstB2.
The recurring label is best-rounded roughly-1kWh unit of 2026B4, which sounds like faint praise and is in fact the right compliment: it is not the lightest thing in its class or the newest, it is the one with the fewest holes. One genuine hole, flagged in our own coverage: it carries no dust or water ingress ratingB0, so it is a unit that lives under the awning rather than out in the weather.
“The LiFePO4 battery genuinely hits 4,000 cycles, AC recharge consistently shows ~1.7-hour full charges, and the 2,000W pure sine wave inverter handles surge loads.”

“After six months across dozens of camping trips, two extended outages, and daily home-office use, it ran every appliance within its 2,000W rating; in a simulated outage it powered a refrigerator, lights, a laptop, and a Wi-Fi router simultaneously.”

“Widely called one of the most well-rounded portable power stations of 2026 — 4,000-cycle LFP battery, 2,000W output, fast wall charging, and expandable design check every important box.”

Who Should Buy Which
Buy the RIVER 2 Max if you…
- →You already own one. Nothing about it stopped working when EcoFlow stopped selling it — 512Wh, 3,000 cycles and a one-hand carry are the same specs they were. Add a second unit only if the workday-length loads keep beating you, and if they do, add a bigger one rather than a matching one.
- →You want this size and shape specifically: a unit under fifteen pounds that you carry rather than lift. That is a legitimate requirement and this unit met it well. The current EcoFlow answer to it is the RIVER 2 Max 500.
- →You have found one in leftover retailer stock and are tempted. It is a good box, but size it for 512Wh permanently because it does not expand, and buy it from somewhere with its own return window.
Buy the Explorer 1000 Plus if you…
- →You work a full day away from an outlet. The remote-workday profile needs 910Wh and the Explorer 1000 Plus finishes it with 164Wh to spare, while the RIVER 2 Max stops 475Wh short of the same day.
- →Your problem is starting things, not carrying them. 2,000W continuous with a 4,000W peak starts and holds every load in all six profiles we run — where it falls short, it falls short on battery rather than inverter.
- →You want the option to grow later. Reviewers put the ceiling at about 5,000Wh with three expansion batteries addedB2, which is the point where it stops being a camping unit and starts being a small backup system.
- →You want one box to cover a run of nights rather than a single night, with enough left over the next morning that you are not rationing before breakfast.
If neither fits
Anyone whose list looks like the blackout or van-life profile should close both tabs. Eight hours of household essentials comes to 1,645Wh and a full van-life day to 4,685Wh; the Explorer 1000 Plus covers about two-thirds of the first and under a quarter of the second, and the RIVER 2 Max is not in that conversation at all. That is a station in the class above these two, or a stacked system with its own expansion batteries. Buying a one-kilowatt-hour box for a whole-house job just means running one extension cord to the fridge and rationing everything else by candlelight.
The Bottom Line
Take the Explorer 1000 Plus. It is the only one of these two you can still buy from its maker, and it would have been the pick regardless: it finishes the workday and the tailgate that the RIVER 2 Max loses, it clears the CPAP night with room for the nights after it, and it refills faster in wall-clock hours despite carrying two and a half times the battery. Losing the buy button on the smaller unit changed the shape of this page, not the answer on it.
The honest catch is the one that made people buy the RIVER 2 Max in the first place: 13.4 pounds in one hand against 32 in two. If that is your whole requirement, the Jackery is the wrong unit and always was. But the answer then is not the RIVER 2 Max either, because it is not for sale. It is the RIVER 2 Max 500, in the same range, doing the same job.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow RIVER 2 Max discontinued?
Yes. EcoFlow's own store has it sold out in every version, and the RIVER 2 Max 500 now occupies that spot in the range. The older unit still works exactly as it always did — 512Wh, 500W, 13.4 pounds, 3,000 rated cycles — and you may still find one at a third-party retailer, but there is no manufacturer price to quote and no buy path we would send you down.
Can the RIVER 2 Max run a CPAP all night?
Yes, for one night. A CPAP runs about 320Wh over eight hours and the RIVER 2 Max holds 435Wh once the flat 85% derate is applied, so it clears the night with 115Wh left. That leftover is a phone charge, not a second night. If you are buying against an outage of unknown length, you want either the larger battery or a guaranteed way to recharge in the morning.
Will either of these get me through a blackout?
Only partly. The eight-hour profile we model comes to 1,645Wh, which is more than either unit holds: the Explorer 1000 Plus covers about 65% of it and the RIVER 2 Max about a quarter. In practice that means fridge, lights, phones and a router rather than the whole house, which is precisely the combination a six-month owner test of the Explorer 1000 Plus ran through a simulated outage. Plan the essentials and let the rest go dark.
Is the Explorer 1000 Plus's expandability worth paying for?
Not as the reason to pick it over the RIVER 2 Max. Its 1,264Wh base is already 752Wh past the RIVER 2 Max's sealed ceiling, so it wins the capacity argument before any expansion battery is involved. Expansion is the question after that one: reviewers put the ceiling at roughly 5,000Wh with three added batteries, which only matters if you expect to outgrow 1,264Wh.
What should I buy instead of the RIVER 2 Max?
Two directions, depending on which half of it you wanted. If it was the size and the one-hand carry, EcoFlow's current equivalent in the range is the RIVER 2 Max 500. If what you actually wanted was more runtime, that is the Explorer 1000 Plus at $699. What does not work is splitting the difference: a second 512Wh unit beside a 512Wh unit gives you two things to keep charged instead of one.
