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 RIVER 3 MAX PLUS is $359 for 858Wh. The Explorer 600 v2 is $499 for 640Wh. That's $140 more for 218Wh less, and it settles most of this page before we get to anything interesting.
The rest of the sheet reads like a photocopy. Both are rated 3,000 cycles, both carry five-year warranties, both take 200W of solar, both give you a 100W USB-C port, both are listed at 30 dB. Where they actually diverge, the EcoFlow is the one in front: 600W continuous against 500W, 1,200W of surge against 1,000W, a 10ms transfer against 20ms.
Jackery wins one thing, and it isn't a small thing if it's your thing. 14.1 lb against 20.8. Just under seven pounds off a box you carry by hand is worth paying for. Just under seven pounds off a box that lives in your trunk is worth nothing. Most of this page is about which of those two people you are.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
Because both are rated for the same 3,000 cycles, lifetime energy tracks capacity and nothing else: 2,574 kWh out of the EcoFlow against 1,920 out of the Jackery. So the up-front gap doesn't wash out over the years, it compounds into 14 cents a lifetime kilowatt-hour against 26. There is no third variable hiding here that rescues the Jackery, because the two units are rated to die at the same cycle count.
RIVER 3 MAX PLUS: $359, 858WhExplorer 600 v2: $499, 640Whboth packs rated 3,000 cycles
Why it mattersAnyone treating these as same-class units to pick by feel should know the feel costs $140 at checkout and roughly double per watt-hour stored.
weight
That weight isn't a mystery, and it isn't waste. The Max Plus is the configuration that already carries the bigger expansion batteryA2A9, which is where both the 858Wh and the extra pounds come from. You're hauling the capacity you paid for. That's a fair trade in a trunk and a bad one on a third-floor walk-up, and it means the choice here is genuinely a carrying decision rather than a value decision.

Why it mattersIf the unit lives in a vehicle or a closet, weight shouldn't cost you $140. If you move it by hand more than a few hundred feet at a time, the Jackery is selling you something real.
Look at the bigger scenarios and the picture sharpens: at 1,645Wh for an eight-hour blackout and 4,685Wh for a day of van life, both units are out by a mile. So the extra 218Wh doesn't move you into a new category. It buys you the top of this one, which happens to be the single scenario this size class is actually bought for: a long day of medium draws away from a wall.
Tailgate Party needs 670Whusable energy after inverter losses: 729Wh for the EcoFlow, 544Wh for the Jackery (85% of rated)8-Hour Blackout needs 1,645Wh and Van Life Daily needs 4,685Wh
Why it mattersIf your reason for shopping is a fridge running overnight, neither of these is the purchase. If it's a long day out, the EcoFlow is the one that reaches the end of it.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The cheaper unit is also the bigger one: $359 for 858Wh against $499 for 640Wh, on identical 3,000-cycle ratings.
cost / lifetime kWh
Fourteen cents a kilowatt-hour against twenty-six. Both packs carry the same 3,000-cycle rating, so lifetime energy is purely a function of how much they hold: 2,574 kWh from the EcoFlow, 1,920 kWh from the Jackery, out of a box that cost $140 less to begin with. Cheaper, larger, same rated life. Spread across the warranty it's $72 a year against $100 for coverage written in the same terms.
One caveat before anyone leans on that too hard. Jackery rates the v2's LFP pack for well over a decade of service, above the 3,000 cycles our database carriesB2, and listings for it don't even agree with each other on rated outputB4. If the higher cycle figure is the true one, the per-kilowatt-hour gap narrows a lot. It still doesn't touch the $140 you hand over on day one, or the 218Wh you don't get for it. And 3,000 cycles is already 8.2 years of daily use, which almost nobody reaches.
Your Life, Your Pick
Selected because: Four of the six scenarios end in neither. The 670Wh tailgate is the only one the extra capacity actually wins.
Four of the six scenarios end in neither, which is the honest headline for this size class rather than a knock on either unit. The one that splits them is the tailgate. 670Wh of coolers, speakers and phone charging lands between 729Wh of usable energy and 544Wh, so one of these finishes the afternoon and one calls it early.
That's the right way to read the extra 218Wh. It isn't a ticket to a different category, it's headroom at the top of this one. A 910Wh working day still beats both of them, and the EcoFlow misses that by a little where the Jackery misses by a lot. A miss is a miss. Buy either of these for a long day away from the wall, not for keeping a house alive.
Portability & Form Factor
Selected because: 6.7 lb separates them, and it is the only spec on the page where the Explorer 600 v2 leads.
weight
Just under seven pounds is the whole case for the Jackery, and it's a real case: 6.7 lb of the EcoFlow's 20.8. Reviewers call it the lightest thing in its capacity classB1, and what owners praise is almost entirely about carrying it and operating itB3. That isn't faint praise. It's the correct praise for a unit whose job is to move.
20.8 lb is still a one-hand carry from the tailgate to the picnic table. It stops being one at the top of three flights, on a trail, or stepping down into a boat. That's the buyer the Explorer is built for, and if that's your evening, the lighter box is worth the money even though it holds less.
Brand Trust
Selected because: Same warranty and same cycle rating, very different apps and very different amounts of help when something goes wrong.
The app gap is the brand fact that touches daily use. EcoFlow's rates 4.6 on iOS and 4.2 on Android. Jackery's sits between 2.3 and 3.3 across both stores, split across two separate apps that want a login even when you're standing next to the unit. If you plan to check state of charge from inside the house while the station sits in the garage, that's not a footnote.
Depth of help follows the same line: roughly 31,000 people in EcoFlow's subreddit against about 2,000 in Jackery's, which is the difference between searching your problem and posting it. Where Jackery pulls back some ground is distribution. It's on the shelf at Costco, Home Depot and Best Buy, and neither company's direct support is the part you want to test, so a store you can walk back into is worth more than either warranty card.

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 comes up 1,371Wh short (about 35% covered), the Explorer 600 v2 1,556Wh (26%). Treat this as partial cover — enough for the essentials in it, not the whole list.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
Neither one clears this, and it's not close. 1,645Wh over eight hours is more than double what the RIVER 3 MAX PLUS can actually deliver from its 729Wh of usable energy, and roughly triple the Explorer's 544Wh. Both can start every load on the list; neither can keep feeding them. If outage coverage is the reason you're shopping, this pair is the wrong shelf.

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 handle this without strain. 320Wh takes 44% of the RIVER 3 MAX PLUS's usable charge and 59% of the Explorer's, and both are listed at 30 dB, so the number you'd care about at 3 a.m. isn't a difference between them. The tiebreak is the second night: 640Wh of it fits inside the EcoFlow's 729Wh usable and doesn't fit inside the Explorer's 544Wh.

LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday

910Wh of laptop, monitor, lights and phone across a working day is more than either one holds. The RIVER 3 MAX PLUS gets to 125% of its usable 729Wh and the Explorer to 167% of its 544Wh, so the EcoFlow misses by a little and the Jackery by a lot. Both accept 200W of solar, which is the actual fix: let it top up on the roof while you work, rather than shopping for a unit that finishes the day cold.

RIVER 3 MAX PLUS
670Wh of coolers, speakers and phone charging is the one place these two genuinely part company. The RIVER 3 MAX PLUS ends the afternoon at 92% of its usable 729Wh, which is no margin at all but is still finishing. The Explorer would need 123% of the 544Wh it can deliver. This is the single scenario where the extra capacity does work you can feel.

Neither unit covers this scenario's 4,685Wh: the RIVER 3 MAX PLUS comes up 3,956Wh short (about 16% covered), the Explorer 600 v2 4,141Wh (12%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Conclusion
August 9, 2026
Verdict: the RIVER 3 MAX PLUS
Take the RIVER 3 MAX PLUS. It's $359 against the Explorer's $499 and holds 858Wh against 640Wh, so you pay $140 less for 218Wh more, on the same 3,000-cycle rating and the same five-year warranty. It also pushes more power (600W continuous and 1,200W surge, against 500W and 1,000W) and hands over faster on a cutover (10ms against 20ms). The Jackery earns its keep on exactly one line of the spec sheet: 14.1 lb against 20.8. If this unit spends its life being carried by one hand over real distance, buy the Jackery and pay for the lightness deliberately. If it lives in a trunk, a closet, or the corner of a garage, there is no argument for it here.

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 Explorer 600 v2 rates 4.2/5 (53rd percentile of 20 Compact-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Explorer 600 v2: what you buy is what you own
The Explorer is sealed at 640Wh with no path to add more, so size it correctly the first time. Before counting that heavily against it, know the other side: the MAX PLUS is the configuration that already has the larger expansion battery attached, which is where its 858Wh comes from. Neither of these is a small unit with room to grow. Buy both on the capacity printed today.
10ms against 20ms, and who that actually matters to
One is line-interactive at 10ms, the other standby at 20ms. The gap only decides anything if you own gear that trips at twenty milliseconds and survives ten, and most people don't. If you're buying either as a desk backup, the more useful spec is how long the handoff buys you: 729Wh of usable energy against 544Wh.
Same five years, different price per year
Identical coverage on both, five years each, so the row is a wash on paper. What isn't a wash is what those years cost: $72 a year on the RIVER 3 MAX PLUS against $100 on the Explorer 600 v2. Buy either from a retailer with a real returns counter and you've added a second layer that doesn't depend on a support queue.
Battery Lifespan in Real Years
The Explorer 600 v2 is rated for 6,000 cycles vs 3,000. In real life: at daily use, that's 16.4 vs 8.2 years. At weekend use (twice a week), it's 58 vs 29 years. One caution reading years across different sizes: a cycle is 640Wh on the Explorer 600 v2 and 858Wh on the RIVER 3 MAX PLUS, so count lifetime energy — roughly 3,840 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.
Full record above — the Test Desk pick is the RIVER 3 MAX PLUS.

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
Polarized, genuinely. Plenty of prepaid-label replacements handled without a fight, and a real vein of long waits and refurbished units sent against new claims. Buying through Costco or Amazon puts a return policy between you and that coin flip.
Community
Around 31,000 people in the EcoFlow subreddit plus an official forum, which is usually the difference between searching your problem and posting it and waiting.
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 very top of the range, the DELTA Pro Ultra platform stacks batteries and inverters into whole-home backup — a flagship path, not a line-wide feature.
Worth knowing
EcoFlow floated paid tiers for advanced app features in early 2025 and backed off after the reaction. The app is the better of the two by a distance, but the company has shown it thinks of parts of it as chargeable.
Jackery
Ecosystem
12-15+ models across Explorer (portable) and HomePower (home backup) series, plus SolarSaga panel ecosystem and innovative form factors
Support
The soft spot. Slow, scripted, strict about receipts, and inclined to send a refurbished unit for a defective one. Keep your proof of purchase somewhere you can find it.
Community
About 2,000 in the Jackery subreddit. YouTube coverage is plentiful on brand recognition alone, but peer troubleshooting is thin when you have an odd fault.
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
It's on the shelf. Costco, Home Depot, Best Buy, Amazon, which means a return counter rather than a support ticket is your first move if something's wrong. On a brand whose direct support is the weak link, that's a real feature and not a marketing line.
Worth knowing
A couple of older models still ship NMC chemistry with a shorter rated lifespan, so check the cycle rating on the specific unit — though most of the current line has moved to LFP. Generally perceived as overpriced for the specs offered compared to newer competitors. App experience is significantly behind rivals.
Analyst note
EcoFlow brings the deeper ecosystem, the better app, and a crowd large enough to have already answered your question. Jackery brings the shelf at Costco. Neither company's direct support is something you want to depend on, so whichever way you go, buy it where you can carry it back over a counter.
Growth path
RIVER 3 MAX PLUS
EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 858Wh.
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.
Explorer 600 v2
FIXED CAPACITYFixed at 640Wh, 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
The Explorer 600 v2 is sealed at 640Wh, which is fine if that covers you. The RIVER 3 MAX PLUS starts at 858Wh and can grow beyond it with EcoFlow expansion batteries — though at this size expansion means longer runtimes on the same loads, not a path to home backup. More hours, not more house.
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 configuration is thin, and what exists comes from hands-on reviewers rather than people a year inA1A5. One put a full recharge from the mains at about 2.3 hoursA1 and called the Max Plus a strong middle ground for weekend off-grid trips and wild parkingA5. There's no six-month check-in here, no cold-weather account, no fan-noise complaint either way.
The most useful thing reviewers do flag is what the 1,200W extended output is actually for: resistive loads like heaters and hair dryers, not sensitive electronicsA7, and not a microwave at allA4. Sub-10ms switchover comes up as a tested strength rather than a datasheet claimA3. Everything else about long-term durability is still unproven, so weigh the specs and the price, not the reputation.

Jackery Explorer 600 v2
Praise for the Explorer 600 v2 is unusually consistent and unusually narrow. It's the lightest thing in its capacity class at about 14 lbB1, and owner feedback lands almost entirely on how easy it is to carry and to operateB3. Nobody is complaining. Nobody is raving about how much it holds, either.
Two flags worth taking into the purchase. Sources disagree on its rated AC output, with some listing 600W where others show 500WB4, and every number on this page uses 500W. And Jackery rates the v2's LFP chemistry for well over a decade, longer than the cycle figure we carryB2. If that holds up, this unit outlives the lifetime-cost math above and deserves a little more credit than it gets there.
“The world's lightest 600Wh-class power station at about 14 lbs — roughly 23% smaller than similar-capacity models.”

Who Should Buy Which
Buy the RIVER 3 MAX PLUS if you…
- →You're kitting out a car-camping or day-trip setup that lives in the trunk between uses. You lift it twice a weekend, and what you actually notice is having 858Wh on Sunday afternoon instead of an empty box.
- →You want the most stored energy you can get under $400 and you don't need it to leave the ground.
- →You run a CPAP and want margin rather than a squeaker. A 320Wh night is 44% of the EcoFlow's 729Wh of usable energy, which leaves a full second night on one charge.
- →You'll actually use the app. EcoFlow's rates 4.6 on iOS against Jackery's 2.3 to 3.3, and there's a subreddit of roughly 31,000 people when something behaves oddly.

- →You carry it, repeatedly. Bike camping, a third-floor walk-up, a photo shoot where the battery moves six times a day. 14.1 lb against 20.8 is the entire argument and it wins on its own terms.
- →You want it today, off a shelf at Costco or Home Depot, with that store's return policy standing behind it rather than a support ticket.
- →Your loads are small and fixed. Phones, a laptop, lights, a CPAP. 544Wh of usable energy plainly covers you, and paying for capacity you'll never touch is its own kind of waste.
If neither fits
If you came here to keep a fridge alive through an eight-hour outage at 1,645Wh, or to run a van at 4,685Wh a day, both of these are the wrong size by several times over and no amount of careful shopping between them fixes that. Move up to a unit that measures its capacity in kilowatt-hours. Same answer if you need to start a microwave or a hair dryer, which even the larger of these two won't doA4.
The Bottom Line
$140 less for 218Wh more, on identical cycle ratings and identical warranties. Everything else here is a footnote to that. The Jackery's app is worse, its continuous output lower, its transfer slower, and its owner community far thinner, but none of that is why it loses. It loses on the two numbers a buyer reads first, and no feature on its side of the table closes a gap like that.
The one honest exception is weight, and it deserves saying once more without flinching. If you carry this thing by hand, up stairs and down trails, 14.1 lb against 20.8 is a fee you can choose to pay with a clear conscience. Everyone else, take the RIVER 3 MAX PLUS and put the difference toward the 200W of solar it'll happily accept.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow RIVER 3 MAX PLUS really cheaper than the Jackery Explorer 600 v2?
Yes, and by a wide margin in both directions. It's $359 against $499, and it holds 858Wh against 640Wh. Work it out per stored watt-hour ($359 divided by 858, $499 divided by 640) and you get about 42 cents against about 78 cents.
Which one is better for a CPAP?
Both run one comfortably. A 320Wh night takes 44% of the EcoFlow's 729Wh of usable energy and 59% of the Jackery's 544Wh. The split shows up on night two: 640Wh for two nights fits inside the EcoFlow's usable capacity and doesn't fit inside the Jackery's. Both are listed at 30 dB, so the spec sheet doesn't separate them on noise.
Can either of these run a fridge through a blackout?
Both can start one, but neither can feed it for long. A realistic eight-hour outage load of 1,645Wh is more than double what the EcoFlow can actually deliver and roughly triple the Jackery's. For genuine outage coverage, shop a class up rather than choosing between these two.
Is the Jackery's lighter weight worth the extra $140?
Only if you carry it. The gap is 6.7 lb, just under a third of the EcoFlow's 20.8. On stairs, a trail, or a boat that's a genuine daily improvement worth paying for. In a trunk it's invisible, and you've spent $140 to get 218Wh less.
Can the RIVER 3 MAX PLUS be expanded further later?
Treat 858Wh as the number you're buying. Reviewers describe the Max Plus as the RIVER 3 Plus with the larger EB600 expansion battery already attached, which is exactly where that 858Wh figure comes from. Size it for what it holds on day one rather than for a growth plan.
