Head-to-head test
EcoFlow RIVER 3 MAX PLUS vs Jackery Explorer 500
EcoFlow stopped selling the RIVER 3 Max Plus, so this stopped being a comparison and became one question about one box: whether 518Wh, a single AC outlet and an 800-cycle rating is the machine you actually needed.

Spec deltas
EcoFlow no longer sells the RIVER 3 Max Plus. That's why there's no price and no buy button on its half of this page, and why the verdict can only land on the Jackery. The specs below are still accurate and still worth reading, because plenty of people own one of these and some will find old retailer stock. What none of them can do is buy a new one from EcoFlow.
What's left on sale is 518Wh, 500W of output, 13.3 lbs and one AC outlet. That's a real machine for a defined job: a CPAP, a phone pile, lights, a laptop top-up, a cooler for an afternoon. Reviewers place the Explorer 500 as an entry-level Jackery suited to weekend warriors and occasional usersB3, which is the honest frame for it. It's also rated for 800 cycles on older lithium-ion cells rather than LFP, and Jackery's own v2 moved to LiFePO4 with a far higher ratingB0B1B4.
If you came here because you were about to buy a RIVER 3 Max Plus, the useful thing to know is that nothing picked up exactly where it left off. The closest unit EcoFlow still sells at this size is the RIVER 2 Pro, which sits below the Max Plus on capacity rather than above it. It's what remains nearby, not a successor in the ordinary sense. If capacity was the reason you wanted the Max Plus, EcoFlow's own steer is to step up to the DELTA 3 Classic instead of sideways.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
And the rating is chemistry, not tuning. The Explorer 500 runs older lithium-ion cells, where Jackery's own v2 is the LiFePO4 version with a far higher cycle ratingB0B4. Used daily, 800 cycles arrives in 2.2 years, after which the pack settles to about 80% of the capacity it started withB1. That's not failure, but it is a different purchase from a box you hand down.
Explorer 500: 800 rated cycles, 518Wh per cycleRIVER 3 MAX PLUS: 3,000 rated cycles, 858Wh per cycleRated lifetime energy: 414 kWh for the Explorer 500, 2,574 kWh for the RIVER 3 MAX PLUS
Why it mattersIf this unit is going to work every day rather than a few weekends a year, buy the LFP version rather than this one.
Then the energy finishes the thought. A remote workday wants 910Wh and the Explorer 500 carries 440 of it, 470Wh short, under half the day. It isn't one socket short of a desk setup; it's half a day short of one.
Explorer 500: 1 AC outlet, 3 USB-A, and a record of zero USB-C portsRIVER 3 MAX PLUS: 3 AC outlets and a 100W USB-CRemote Workday needs 910Wh; the Explorer 500 has 440Wh usable after the flat 85% derate applied to every unit here
Why it mattersAnyone planning to run a laptop-and-monitor desk off this should size up instead of buying an adapter.
Endurance says the same thing twice. An eight-hour outage wants 1,645Wh and the Explorer 500 covers 440 of it, about a quarter, 1,205Wh short. The single hands-on review we have on the RIVER family flagged that fast transfer as the feature worth havingA3, which is a fair reading and no use to a buyer, because it sits on the half of this page with no buy button.
RIVER 3 MAX PLUS lists a UPS mode rated no worse than 10ms, which is a ceiling rather than a measured resultThe Explorer 500's spec sheet lists no UPS mode8-Hour Blackout needs 1,645Wh; the Explorer 500 has 440Wh usable
Why it mattersAnyone shopping for outage protection should skip this pair and look at a larger station that lists a UPS mode.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Four of these six loads are too big for either unit, so the useful question is which of the remaining two the box you can actually buy finishes.
Four of these six loads are beyond both boxes, which is the most useful thing this section tells you. Van life wants 4,685Wh and the Explorer 500 brings 440 of it. A camping weekend wants 2,100. Those aren't near misses, they're a different product category, and no amount of choosing between these two units fixes them.
The two rows with a winner both go to the unit you can't buy, and only one of them is close. A CPAP night is about 40W for eight hours, 320Wh, which the Explorer 500 finishes with roughly 120Wh of its usable 440 left: comfortably, not barely. The tailgate is where it stops, 230Wh short of the 670Wh an afternoon of cooler and speakers needs. Work out which of those two your day looks like before you spend anything.
What the Specs Don't Tell You
Selected because: Six cards fire on this pair, and they hold the real separation: solar ceiling, app control, expansion, UPS mode, warranty term and a 3,000-versus-800 cycle rating.
rated cycles
The six cards split cleanly: four describe the unit you can buy, two describe the one you can't. Start with the four. The Explorer 500 tops up at a 100W solar ceiling, which is 5.2 hours of good sun to refill 518Wh and a best case at that. It has no app, so checking the charge level means walking to it. It's sealed at 518Wh, so what you buy is the ceiling. And it's rated for 800 cycles.
The other two cards are the ones that sting: a UPS mode rated no worse than 10ms, and five years of warranty against two. Both belong to the retired unit. That's the shape of this whole page, and it's why the Jackery's case has to be made on weight, price and availability rather than on the spec sheet.
Portability & Form Factor
Selected because: 13.3 lbs against 20.8 is the one column the unit still on sale wins outright, and at this size portability is most of the point.
weight
13.3 lbs is the Explorer 500's best argument. Seven and a half pounds lighter than the RIVER 3 Max Plus (20.8 against 13.3) is the difference between a two-hand carry from the car and a one-hand swing out of the trunk with a cooler in the other. Reviewers describe a genuinely compact unit at about 13 lbsB2, and at this size that's most of what you're paying for. Nobody buys 518Wh to back up a house. They buy it so the box goes where they go.
Brand Trust
Selected because: The replacement for a retired EcoFlow is another EcoFlow, so choosing the Jackery instead means choosing between two very different support, app and retail records.
The brand column matters more than usual here, because the replacement question crosses it. Jackery's real asset is shelf space: Costco, Home Depot, Best Buy and Amazon all carry it, and that's worth something concrete. Both brands' support records draw the same complaints about slow replies and refurbished units sent against new claims, and a retailer's return window is the fastest route around that for either one.
EcoFlow's pull is the opposite kind. It has the deepest range in portable power and a community roughly fifteen times the size of Jackery's on Reddit, about 31,000 members against 2,000. Jackery's app is the weakest of the major brands at 2.3 to 3.3 out of 5, with mandatory login even offline, which takes some of the sting out of the Explorer 500 having no app at all. You can't be let down by software you were never issued.

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 500 1,660Wh (21%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Keep the essentials running through a night without power
Neither unit
Neither box keeps a household running for an evening. The list here adds up to 1,645Wh, and the Explorer 500 carries 440 of it usable, about a quarter, leaving it 1,205Wh short; the RIVER 3 Max Plus reaches roughly 44%. At this size you're not backing up a house, you're choosing three things to keep alive, the router and the phones and one lamp, and accepting that the fridge isn't on the list.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
RIVER 3 MAX PLUS
Both of these sleep through the night, so capacity isn't the question. The RIVER 3 Max Plus takes the row on paper and finishes with more in the tank, but the practical read is that the Explorer 500 covers a 40W machine for eight hours and still holds about 120Wh of its usable 440. What the spec sheets can't settle is the one thing that matters at 3 a.m., whether a fan spins up eighteen inches from your head. Both makers publish a noise rating, they don't measure the same way, and neither figure describes a draw this small. Go looking for hands-on reports before either unit lands on a nightstand.

Neither unit
Neither finishes a work day. The load is 910Wh; the Explorer 500 carries 440Wh usable and comes up 470Wh short, under half of it, while the RIVER 3 Max Plus reaches about 80% and still quits before five o'clock. Plan the Jackery as a morning, and plan on a wall outlet by lunch.

RIVER 3 MAX PLUS
This is the row where 518Wh stops being enough. The afternoon wants 670Wh, and the Explorer 500 has 440Wh usable, landing 230Wh short at about two-thirds of the way through. Both units start the 400W peak without complaint, so the limit isn't the inverter, it's the tank, and the only one here that finishes does it with 59Wh to spare. Bring a second battery or a smaller speaker.

Runtime model
Runtime = (rated capacity × 0.85 inverter efficiency) ÷ device wattage. Solar recharge estimates assume panels deliver 70% of rated output. Cold weather, battery age, and stacked loads reduce real-world results.
Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
See the full weight table and data sourcing on our methodology page →Class ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews — no buyer opinions feed it. We score every station on size-independent quality (value, output, portability, endurance, ports, warranty, and more), then percentile-rank it against the other units in its capacity class, so a class-leading compact unit and a class-leading whole-home unit can both earn 5★. Here, RIVER 3 MAX PLUS rates 4.9/5 (95th percentile of 20 Compact-class units), and Explorer 500 rates 3.3/5 (1st percentile of 20 Compact-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.
Explorer 500: A 100W Ceiling Is a Day, Not a Morning
518Wh at a 100W rated solar ceiling is about 5.2 hours of sun to refill from empty, and that's the best case: it assumes the panel is aimed right and the sky is clear, and real days give you less. Treat solar here as a top-up between wall charges rather than the way this unit lives. For scale, the RIVER 3 Max Plus accepts 200W, which puts its larger 858Wh pack back in roughly 4.3 hours. Bigger battery, less of the day.
Explorer 500: No App Control
Without app control, you have to physically walk to the Explorer 500 to check battery level, adjust settings, or monitor power draw. The RIVER 3 MAX PLUS lets you do all that from your phone, including getting low-battery alerts.
Explorer 500: Fixed Capacity
The Explorer 500 is sealed at 518Wh, and that is the ceiling. Normally the counterpoint would be that the RIVER 3 MAX PLUS can add expansion batteries, but that isn't a live option here: the RIVER 3 MAX PLUS is no longer sold, and EcoFlow points owners to the RIVER 2 Pro. For a new purchase the expansion question doesn't arise between these two, so the Explorer 500's fixed 518Wh is simply what you get.
The UPS Mode Belongs to the Retired Unit
The RIVER 3 Max Plus can sit between the wall and your gear and hand the load to battery when the grid drops, rated no worse than 10ms, which on paper is quick enough that a router or a desktop never notices. The Explorer 500 lists no UPS mode, so whatever is plugged into it goes dark with the grid and comes back when you get there. It's the sharpest spec difference on this page and the least useful one, because the unit that has it isn't on sale.
Five Years of Cover Against Two
Our record carries five years on the RIVER 3 Max Plus and two on the Explorer 500. The longer term reads better and means less here, because cover on a unit the maker no longer sells is worth what the maker chooses to honor, and EcoFlow publishes no parts or service once the window closes. Two live years on the Jackery is a shorter promise from a company still shipping the product. With either brand, the protection that actually gets used is the return policy at whatever shop you bought it from, which is a good reason to buy one of these somewhere with a real returns desk.
Battery Lifespan in Real Years
The RIVER 3 MAX PLUS is rated for 3,000 cycles vs 800. In real life: at daily use, that's 8.2 vs 2.2 years. At weekend use (twice a week), it's 29 vs 8 years. One caution reading years across different sizes: a cycle is 858Wh on the RIVER 3 MAX PLUS and 518Wh on the Explorer 500, so count lifetime energy — roughly 2,574 kWh against 414 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
Neither is sold new any more, so there is no price left to work a cost per kWh from, and what either costs you now depends on the used market. The hardware comparison still holds: over its rated life the RIVER 3 MAX PLUS delivers about 2,574 kWh and the Explorer 500 about 414 kWh.
Brand trust
EcoFlow
Ecosystem
Largest in portable power — 12-15 models across DELTA Pro, DELTA 3, and RIVER 3 series, plus solar panels and smart home panels
Support
US-based phone/email/chat support (1-800-368-8604). Experiences are polarized — many report hassle-free prepaid-label replacements, but others report long waits and refurbished units sent for new claims. Pro tip: buying from Costco or Amazon gives you a stronger return safety net.
Community
Largest community in the space — Reddit r/Ecoflow_community (~31K members), multiple Facebook groups, and an official community forum
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
Fastest-charging technology (X-Stream), deepest product ecosystem, and most active innovation cadence. At the top of the range sit two whole-home paths: the TITAN line, one 5 kWh unit that grows to 30 kWh, and the DELTA Pro Ultra platform, which stacks batteries and inverters further — flagship paths, not line-wide features.
Worth knowing
EcoFlow publishes no parts or service once a unit is out of warranty, which is a specific thing to weigh on a model the company has stopped selling. The flip side is the deepest range in portable power and by far the largest owner community in the category, which is where most out-of-warranty answers actually come from.
Jackery
Ecosystem
12-15+ models across Explorer (portable) and HomePower (home backup) series, plus SolarSaga panel ecosystem and innovative form factors
Support
Jackery's support record draws the same complaints EcoFlow's does: slow or scripted replies, strict receipt requirements, refurbished units sent against claims on clearly faulty hardware. The practical answer is the same for both brands. Buy from Costco or Amazon and let the retailer's return policy be your first line of warranty.
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 own published caution is to check the cycle rating on the specific model, because a few older units in the line are rated for far shorter lives than the current LFP ones. The Explorer 500's 800-cycle rating is exactly the number that caution is about, and it's the most important line on the Jackery's side of this page.
Analyst note
These two brands are strong in opposite places. EcoFlow has the range, the app and the community; Jackery has the shelf space, which is why you can hold one before you buy it and walk it back if you don't. On this page that asymmetry settles nothing, because only one of the two units is still for sale. It is, though, the reason the Explorer 500 is a real option rather than a default.
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 500
FIXED CAPACITYFixed at 518Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 100W of solar. Limited to a single portable panel.
Limited ports. You'll likely need a power strip or splitter.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Neither of these is sold new any more, so there is no growth path to buy into on either side. If you already own one: the RIVER 3 MAX PLUS takes expansion batteries and the Explorer 500 is fixed at 518Wh. As a purchase decision, expandability isn't the question here.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 3 MAX PLUS
Field evidence on this exact unit is thin, and it's worth saying why. Our research turned up no owner threads naming the RIVER 3 Max Plus specifically, only hands-on reviews, several of which were really testing the smaller RIVER 3 or RIVER 3 PlusA0. What we do have agrees on one structural point: the Max Plus wasn't a distinct machine so much as the RIVER 3 Plus with the larger EB600 battery attached, which is where the 858Wh comes fromA2A9. One review clocked a full recharge from mains at around 2.3 hoursA1, and singled out the sub-10ms transfer as the feature worth havingA3.
The one caution in that material concerns the boosted output, and the sources don't quite agree. One frames the extended 1,200W as built for resistive loads such as heaters and hair dryers, explicitly not sensitive electronics like desktop PCsA7. Another says a high-power hairdryer or a microwave is out of reach entirely, as it is on most units this sizeA4. Read the surge figure as headroom for a kettle, not as permission to plug in a tower.
“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.”

Jackery Explorer 500
The Explorer 500's file is short and unambiguous on the thing that matters. It's 518Wh and 500W on traditional lithium-ion cells, with Jackery rating 80% capacity retention at 800 cyclesB1, and the newer v2 is the LiFePO4 version with a far higher cycle ratingB0B4. Reviewers place it as an entry-level Jackery for weekend warriors and occasional usersB3, and describe a compact box at about 13 lbsB2. Nothing in the record contradicts the spec sheet, which is its own quiet reassurance for an older design: it is exactly what it says it is, including the part about the cycles.

Who Should Buy Which
Buy the RIVER 3 MAX PLUS if you…
- →You already own a RIVER 3 Max Plus. Keep using it. At 3,000 cycles the pack is rated to outlast most of what you'd replace it with, and nothing about the unit changed when the listing came down.
- →You're weighing one that's still sitting in retailer stock. The specs on this page describe it accurately, 858Wh and 600W with a UPS mode rated no worse than 10ms, and that comparison is why this page exists. What you'd need to establish is who's selling it and what their return policy is, because on a unit the maker has stopped selling, the channel behind the sale is doing most of the work a warranty normally does.
Buy the Explorer 500 if you…
- →The weekend user with a defined list: a couple of phone charges, string lights, a CPAP, a laptop top-up. At $359 (last listed price), 518Wh and 13.3 lbs is a sensible amount of machine for exactly that week.
- →The CPAP user who wants one night covered and doesn't want to think about it again. About 40W for eight hours is 320Wh against 440Wh usable, so you're not running the pack to the floor to get to morning.
- →The buyer who wants a station from a shelf they can walk back to. Jackery is in Costco, Home Depot, Best Buy and Amazon, and with either of these brands a retailer's return window is the most reliable protection on offer.
If neither fits
Skip both if you're buying for a blackout, a van, or daily service. An eight-hour outage wants 1,645Wh and the Explorer 500 covers about a quarter of it with no UPS mode to catch the drop; van life wants 4,685Wh, which is a different category of purchase and a different budget. And if you'll cycle a unit every day, 800 cycles is 2.2 years, so look at Jackery's LFP v2B4. If you came here for the retired EcoFlow specifically, the RIVER 2 Pro is the nearest unit EcoFlow still sells at this size, and the DELTA 3 Classic is the step up if capacity was the point.
The Bottom Line
The RIVER 3 Max Plus is off EcoFlow's shelf, so the recommendation is the Jackery Explorer 500 by the only route that was ever open: it's the one with a buy button. Take it if your job is a small, defined one, a CPAP night or a laptop or lights and a cooler for an afternoon, and you want 13.3 lbs you can carry in one hand from a car.
Buy it knowing which number follows you home. On daily service this pack reaches its cycle rating in a couple of years, where the retired EcoFlow would still be years away from its own, and the energy each one delivers across that life isn't close. One AC outlet, no USB-C, no UPS mode. If that describes your actual week rather than your occasional weekend, the Explorer 500 is the wrong size of purchase, and the money belongs in a bigger station or in Jackery's LFP v2B4.
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, which is why this page shows no price and no buy button on its side. The specs stay accurate and retailer stock may still turn up, but it has left the maker's range, so it can't be the recommendation here no matter how it compares.
What replaced the EcoFlow RIVER 3 Max Plus?
Nothing replaced it exactly. The closest unit EcoFlow still sells at that size is the RIVER 2 Pro, which sits below the Max Plus on capacity rather than above it, so it's what remains nearby rather than a successor in the usual sense. If capacity was your reason for wanting the Max Plus, EcoFlow's own steer is to step up to the DELTA 3 Classic instead of across.
Can a Jackery Explorer 500 run a CPAP all night?
Yes, with margin. A CPAP draws about 40W, so eight hours is roughly 320Wh, and the Explorer 500 has about 440Wh usable once you apply the flat 85% derate used across this site. That leaves around 120Wh in reserve, so a humidifier or a long night won't put you on the floor. What no spec sheet settles is how the fan behaves at a draw that small, which is the thing that actually wakes people.
How long will a Jackery Explorer 500 last?
It's rated for 800 cycles, after which the pack holds about 80% of its original capacity rather than dying. Used daily that's around 2.2 years to the rating; twice a week, about 7.7 years. It runs older lithium-ion cells, and Jackery's v2 is the LiFePO4 version with a far higher rating if longevity is what you're buying.
Will the Jackery Explorer 500 keep a computer running through a power cut?
No. Its spec sheet lists no UPS mode, so anything plugged into it goes dark when the grid does and comes back when you get to it. The RIVER 3 Max Plus is the unit here rated for a transfer no worse than 10ms, and it's the one you can't buy. For genuine ride-through you want a larger station that lists a UPS mode, not either of these.
