Head-to-head test
EcoFlow RIVER 3 vs Jackery Explorer 600 v2
The RIVER 3 can't get a CPAP through the night; the Explorer 600 v2 does it with charge to spare. That's an energy gap, not a power gap, and it's the entire story behind this $260 price difference (on last listed prices).

Spec deltas
Between the EcoFlow RIVER 3 and the Jackery Explorer 600 v2, the Explorer 600 v2 is the more capable unit. It's the only one of the two that gets a CPAP through the night, and it edges the RIVER 3 on lifetime cost per kWh, if only by a cent. That's the verdict for anyone actually cross-shopping these two.
It's also nearly the whole story. Strip away capacity, weight, and price, and these two are close to identical: both rated for 3,000 cycles, both carry a 5-year warranty, both sit at 30dBA, both switch over in 20ms. The RIVER 3's 300W rating and the Explorer 600 v2's 500W are both overkill for a phone or a CPAP. The entire comparison comes down to watt-hours: 245 against 640, a 2.6x gap.
So the real question isn't which one wins a head-to-head — it's whether either belongs on your list at all. If your job is charging phones, a laptop, or getting a CPAP through the night, keep reading. If it's an actual camping trip, a home blackout, or van life, both of these are the wrong size, and no amount of comparing them here will fix that.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
That makes the RIVER 3 a poor fit for any all-night continuous load, no matter how gentle the wattage, while the Explorer 600 v2 has real reserve to spare after the same night's use.
CPAP Overnight needs about 320Wh; the RIVER 3 (245Wh) needs 154% of its capacity to cover it and can'tThe RIVER 3 is rated for 300W continuous output, far more than a CPAP actually drawsThe Explorer 600 v2 (640Wh) covers the same 320Wh load using just 59% of its capacity
Why it mattersAnyone buying to run a CPAP, oxygen concentrator, or similar overnight medical load should start at the Explorer 600 v2's capacity class or larger — wattage was never the constraint here, watt-hours were.
Cost-per-lifetime-kWh technically favors the Explorer 600 v2, but by one cent — a rounding difference, not an argument. The real cost decision is the $260 (on last listed prices) that leaves your wallet on day one, not a long-run value gap that barely exists.
RIVER 3 costs $239 (last listed price); Explorer 600 v2 costs $499 (last listed price) — 2.5x the priceAmortized over a full 3,000-cycle life, that's $0.27 per lifetime kWh for the RIVER 3 versus $0.26 for the Explorer 600 v2Both carry an identical 5-year warranty and 3,000-cycle rating
Why it mattersDon't buy either one for 'the long-run savings' — there isn't a meaningful one. Decide based on whether you need 245Wh or 640Wh, and let the $260 (on last listed prices) upfront difference be the number that actually matters.
weight
'Lighter' and 'more portable' stop being the same claim once real capacity is the goal. For a fixed weight budget, the Explorer 600 v2 converts more of it into usable power; the RIVER 3 only wins portability outright if the number on the shelf — 7.8 lbs versus 14.1 — is what matters to you, not the energy packed into each pound.
RIVER 3 weighs 7.8 lbs and holds 245Wh — about 31Wh per pound carriedExplorer 600 v2 weighs 14.1 lbs and holds 640Wh — about 45Wh per pound carriedBoth share an identical 30dBA noise rating and 20ms UPS switchover
Why it mattersIf you're packing to a hard weight limit — a backpack, a kayak hatch, a carry-on — run the Wh-per-pound math before assuming the smaller unit is the more 'portable' choice for the power you actually need.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: 5 of 6 tested scenarios fail both units outright, and the 6th (CPAP) is the only clean resolution in the whole comparison — this is where the real argument lives.
Run these two through six real scenarios and they agree on five of them: neither is big enough. Weekend Camping, an 8-hour blackout, a remote workday, a tailgate, and a full day of van life ask for somewhere between 670Wh and 4,685Wh — every one of those numbers beats the Explorer 600 v2's entire 640Wh tank, let alone the RIVER 3's 245Wh. None of that is a power problem: both units' 300W and 500W continuous ratings are nowhere near the bottleneck. There simply isn't enough energy on board for a job this size.
CPAP Overnight is the exception, and it's instructive precisely because it's a small, boring load: about 320Wh across the night. The RIVER 3 needs 154% of what it holds to get there — not a power problem (300W is comically more than a CPAP pulls), an energy problem, and it runs out before morning. The Explorer 600 v2 finishes the night having used just 59% of its 640Wh. That 154-versus-59 split is the entire practical difference between these two units: one has enough tank for an overnight commitment, the other doesn't.
Portability & Form Factor
Selected because: 7.8 lbs vs 14.1 lbs is a real difference, and the Wh-per-pound math flips the intuitive 'smaller is more portable' read.
weight
The RIVER 3 is the lighter unit in absolute terms — 7.8 lbs against the Explorer 600 v2's 14.1 — but pick either one up expecting Wh-per-pound and the math flips. The RIVER 3 delivers about 31Wh for every pound carried; the Explorer 600 v2 delivers about 45. The 'bigger, heavier' unit is actually the more efficient one at turning weight into usable energy.
In absolute terms, though, 7.8 lbs is a one-hand lift that disappears into a daypack. 14.1 lbs is still a one-hand carry, just a denser one — closer to a full 2-liter bottle than a laptop. Neither needs two hands or a cart; the real difference is 6.3 lbs, and whether that matters depends entirely on what you're carrying it in.
Lifetime Value
Selected because: The 2.5x price gap nearly vanishes once amortized across cycle life — worth surfacing since it undercuts the instinct to just buy the cheaper unit.
The sticker prices are 2.5x apart — $239 (last listed price) against $499 (last listed price) — but stretch each unit across its full 3,000-cycle life and that gap nearly disappears: $0.27 per lifetime kWh for the RIVER 3, $0.26 for the Explorer 600 v2. On paper, the bigger unit is the cheaper one to own, but by a single cent. That's a coin-flip, not a discount.
Both are rated for the same 3,000 cycles, which works out to roughly 8.2 years at daily use, 28.8 years at twice-weekly weekend use, or 57.7 years at once a week — identical figures for both units, since cycle count doesn't care how big the tank is. The real financial question here was never cost-per-kWh; it's whether the $260 (on last listed prices) upfront difference buys you capacity you'll actually use.
What the Specs Don't Tell You
Selected because: Only one Test Note fires (warranty cost-per-year), and it's also the natural place to flag the Explorer 600 v2's marketing-vs-bench figure gap.
rated cycles
The one real gotcha the spec sheet hides is how warranty cost scales with price. Both units carry the same 5-year term, so coverage length isn't a factor — but that term costs about $40 a year on the RIVER 3's $239 (last listed) price tag and about $100 a year on the Explorer 600 v2's $499 (last listed price), the same 2.5x split as the sticker price. A 5-year warranty sounds identical until you notice one of them is a pricier 5 years.
One more thing worth flagging before you cross-shop: you'll find the Explorer 600 v2 advertised elsewhere with a punchier output rating and a cycle count well above what's on our spec sheetB4. Every number in this comparison — 500W continuous, 3,000 cycles — comes from our own bench data rather than the marketing sheet, and we hold the RIVER 3 to the same standard. Treat any comparison quoting a bigger number for either unit with a little skepticism.

We ran the math on seven 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
A two-night camping trip — lights, a cooler, device charging, maybe a fan — runs about 2,100Wh. That's more than three times what the Explorer 600 v2 holds and more than eight times the RIVER 3's tank. Both are the wrong size for this job; look at a station built for multi-day camping instead.

LOAD Phone Charger 15W×6h · LED Lights 40W×8h · Box Fan 75W×14h · CPAP Machine 40W×16h
SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
An 8-hour blackout — a cycling fridge, some lights, a router, phones — needs around 1,645Wh. That's about two and a half times the Explorer 600 v2's entire capacity, and the RIVER 3 isn't close. If home blackout coverage is the actual goal, size up well beyond either of these.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Explorer 600 v2
An all-night CPAP draws a small, steady load, but eight hours of it adds up to about 320Wh. The RIVER 3's 245Wh doesn't stretch that far — it comes up short before morning. The Explorer 600 v2 does the job and still has real charge in reserve when the alarm goes off.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
Neither unit
A full remote workday — laptop, monitor, phone, maybe a router — adds up to roughly 910Wh. That's still more than the Explorer 600 v2's 640Wh can cover, and well beyond the RIVER 3's reach. Both are day-trip units, not all-day-desk replacements.

Tailgate Party
Game day power for the crew
Neither unit
A tailgate's tally — speaker, string lights, a small fan, phones — runs about 670Wh, close enough to the Explorer 600 v2's 640Wh that it runs out before the game's over. The RIVER 3 runs out well before that. Neither has quite enough tank for a full tailgate.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Van life's daily draw — fridge, lighting, a water pump, laptops, phones — runs about 4,685Wh a day. That's roughly seven times the Explorer 600 v2's entire capacity and better than nineteen times the RIVER 3's. This is the clearest mismatch on the page: neither unit is in the size class daily van life actually requires.

Afternoon Off-Grid
Phones and a speaker at the park, beach, or campsite — the small-unit job description
Either unit
This row is here for the RIVER 3's class of job: phones and a speaker, 100Wh across an afternoon. Both cover it — the RIVER 3 finishes at 48% used, and the Explorer 600 v2 barely notices it. For this job the Explorer 600 v2's extra capacity is dead weight, not headroom; at 7.8 lbs the RIVER 3 is the easier carry, though neither is sold new any more.

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 rates 4.1/5 (50th percentile of 25 Personal-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.
Same Coverage Length, Different Price Per Year
Both carry a 5-year warranty, so the term itself is a wash. What differs is what each year of coverage costs: about $40 a year on the RIVER 3's $239 (last listed) price tag, and about $100 a year on the Explorer 600 v2's $499 (last listed price) — the same 2.5x split as the sticker price, just spread across sixty equal months instead of paid once.
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 245Wh on the RIVER 3, so count lifetime energy — roughly 3,840 kWh against 735 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 delivers about 735 kWh and the Explorer 600 v2 about 3,840 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
Tested subscription paywalls for advanced app features in early 2025 before community backlash paused the plan. No parts or service offered out of warranty.
Jackery
Ecosystem
12-15+ models across Explorer (portable) and HomePower (home backup) series, plus SolarSaga panel ecosystem and innovative form factors
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
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 and Jackery are close competitors. Both have established support channels and growing ecosystems. Compare their specific warranty terms and community size for your peace of mind.

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 is fixed at 245Wh and the Explorer 600 v2 is fixed at 640Wh. 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
Coverage on the RIVER 3 skews comparative — most of it measures against the RIVER 2 rather than standing the unit alone — but the story is consistently one-directional. EcoFlow's own materials and review sites call the fan noise a real generational jump, putting it under 30dB and branding it 'whisper quiet,' quieter than a libraryA1. The newer platform also adds water resistance and a faster UPS switchover over the RIVER 2A2, and reviewers frame it as an outright strict upgrade: more capacity, less weight, a lower price than its predecessor, all at onceA4.
When reviewers recommend the RIVER 3 for camping, van life, or home UPS backup, it's specifically over the older RIVER 2, on durability and noise groundsA3 — that's a different claim than 'this 245Wh unit covers a camping trip by itself,' and our own scenario testing above says it doesn't. Treat the ledger here as evidence the RIVER 3 is the right EcoFlow to buy at this size, not evidence that this size is enough.
“The RIVER 3 operates under 30 dB — EcoFlow calls it 'whisper quiet,' quieter than a library — one of the most significant upgrades over the louder RIVER 2.”

Jackery Explorer 600 v2
This is a newer, smaller Jackery unit, and coverage is thinner than the RIVER 3's — it's also been prone to selling out as production ramps. What's there agrees: reviewers call it the lightest 600Wh-class station on the marketB1, and owners describe it as affordable, easy to carry, and easy to operateB3. The shift to LFP chemistry draws real praise too, prized as more stable and less overheating-prone than the older NMC packs Jackery has used elsewhere in its lineupB2.
One flag before you cross-shop: you'll see this unit advertised elsewhere with a punchier output rating and a cycle count well above what's on our spec sheetB4. Every number in this comparison — 500W continuous output, 3,000 cycles — comes from our own bench data, not the marketing sheet, which is why our totals may read a little more conservative than what you'll find on other sites.

Who Should Buy Which
Buy the RIVER 3 if you…
- →The RIVER 3 is for small jobs only: a phone, a tablet, a laptop, maybe a mini fan — the stuff that fits inside 245Wh with room to spare. At 7.8 lbs and $239 (last listed price), it's the cheaper, lighter grab-and-go pick, as long as you're not asking it to run anything overnight or all-day; every scenario on this page says it can't.
Buy the Explorer 600 v2 if you…
- →The Explorer 600 v2 is for anyone who needs a real overnight buffer without stepping up to a much bigger station: a CPAP, a modest home-office backup, a phone-and-laptop kit for a long day away from outlets. It costs $260 more (on last listed prices) and carries 6.3 lbs more, but it's the only one of these two that clears an actual scenario in this comparison, and it does it with real reserve left over.
If neither fits
If you're planning an actual camping weekend, a home blackout, a full remote workday with real equipment, a tailgate, or van life, neither of these is the right size — all five of those scenarios beat both units by a wide margin. Look at a station in the next capacity class up, or higher; coming back to this page won't change the math.
The Bottom Line
For anyone actually choosing between these two, take the Jackery Explorer 600 v2: it's the only one that gets a CPAP through the night, it edges the RIVER 3 on lifetime cost per kWh (barely), and it scores higher on our PowerScore breakdown (1989 vs 1632). Don't mistake that for a rout, though — five of the six scenarios we tested beat both units outright, and the RIVER 3's $239 (last listed price), 7.8 lb case is still the right one for anyone who just needs small electronics topped up.
If you need real overnight capacity, get the Explorer 600 v2. If you just need phones charged and $260 (on last listed prices) back in your pocket, the RIVER 3 was never a bad answer — just to a different question.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the EcoFlow RIVER 3 run a CPAP all night?
No. An all-night CPAP load needs about 320Wh, and the RIVER 3's 245Wh needs 154% of its capacity to cover that — it runs out before morning. The Jackery Explorer 600 v2 handles it easily, using just 59% of its 640Wh.
Is the Jackery Explorer 600 v2 worth $260 more (on last listed prices) than the RIVER 3?
Not for long-run savings — amortized over a full 3,000-cycle life, the two cost about the same per kWh delivered ($0.27 vs $0.26, essentially a rounding difference). The $260 (on last listed prices) buys 2.6x the capacity (640Wh vs 245Wh) and the only scenario win in this comparison (CPAP Overnight), not a better long-term deal.
Which is more portable, the RIVER 3 or the Explorer 600 v2?
The RIVER 3 is lighter outright — 7.8 lbs against 14.1 lbs. But per pound carried, the Explorer 600 v2 actually holds more energy, about 45Wh a pound versus about 31. 'Portable' depends on whether you're optimizing for the number on the shelf or the energy packed into a fixed weight budget.
Why do some listings show the Jackery Explorer 600 v2 at 600W output or 6,000+ cycles?
You'll see those figures in some marketing and reviews, but our own bench data shows 500W continuous output and a 3,000-cycle rating, and that's what this entire comparison is built on. Treat the higher numbers with some skepticism until they show up in independent testing.
Can I add a battery or expansion pack to either one later?
No — both are sealed, fixed-capacity units with no expansion path. Buy the capacity you actually need today, 245Wh or 640Wh, because neither one grows with you later.
