Head-to-head test
EcoFlow RIVER 2 vs Goal Zero Yeti 6000X
One of these is a 7.8 lb box you carry to the picnic table and the other is a 106 lb appliance you wheel into a corner once, and since EcoFlow stopped selling the small one, the only live answer here is the one that never leaves the house.

Spec deltas
EcoFlow has stopped selling the RIVER 2, so one side of this comparison no longer carries a price. That settles the recommendation before we start: the Goal Zero Yeti 6000X is the only unit here you can buy new, and the RIVER 2 240 is what EcoFlow sells in the older unit's place.
It also settles a comparison that was never much of one. 256Wh in a 7.8 lb box against 6,071Wh in a 106 lb appliance is not two options, it is two different products sharing a category name. Six of the seven scenario rows on this page end with the RIVER 2 short of the load, and the two rows nobody wins are the ones where the Yeti cannot get to the campsite in the first place.
So read this page for the size question rather than for the verdict. If you need a battery that stays put and carries a house through the night, the Yeti does that, and weight, cycle life and warranty are what it costs you. If you need something you can pick up with one hand, the 6000X was never the answer, and the RIVER 2 leaving the range does not change which end of the market you belong in.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
weight
There is no version of the Yeti you can carry and no version of the RIVER 2 that finishes a weekend. That is why two rows here end with nobody winning instead of with a close call: those jobs need energy and legs, and each unit brings exactly one.
Yeti 6000X: 6,071Wh at 106 lbs, flagged stationaryRIVER 2: 256Wh at 7.8 lbsWeekend Camping and Tailgate Party both resolve to 'neither'
Why it mattersIf you are choosing between these two you are not choosing a product, you are deciding which half of the problem you are willing to give up.
The one row the Yeti wins on a thin margin belongs to the only buyer who cycles it every day, and daily cycling is precisely what spends 500 cycles. It passes van life new and misses it at the end of its rated life, for the same person.
Van Life Daily needs 4,685Wh; the Yeti passes at 91% of usable capacity with 475Wh spareYeti 6000X: 500 cycles, lithium NMCB1at the end of that rating the 6,071Wh pack is effectively about 4,857WhB4scenario usable capacity is nameplate cut by a flat 85% derate
Why it mattersBuying this as a daily driver means buying the expansion battery with it or buying bigger; buying it to sit and wait for outages means the cycle rating barely touches you.
Those are two different failures and neither unit fixes the other's. The Yeti runs a fridge all night and still lets everything plugged into it drop the instant the grid goes. The RIVER 2 keeps a modem from blinking and runs dry long before morning. For anything that must neither blink nor stop, medical gear being the obvious case, the answer is not on this page.
RIVER 2 lists a UPS mode rated no worse than 30msthe Yeti 6000X's record carries no switchover figure and its spec sheet lists no UPS modeRIVER 2: 218Wh usable against the 320Wh CPAP overnight profilethe RIVER 2 has left EcoFlow's range
Why it mattersAnyone shopping for uninterrupted overnight power should leave with a shortlist of units that publish a switchover figure and hold a night's capacity, and cross both of these off it.
solar input
That is what makes it a multi-day blackout unit, and it is not the mechanism people shop for. Capacity buys the first night, and the modest 600W input is enough only because the nightly draw is small against the pack. On the RIVER 2 the ratio runs the other way: 110W refills 256Wh in a couple of hours, but the pack it refills is empty again by bedtime.
Yeti 6000X: 6,071Wh, 600W solar input, full recharge in 12 hours from the included 600W AC chargerB3the 8-Hour Blackout row draws 1,645Wh and leaves the Yeti at 32% usedRIVER 2: 110W solar input against 256Wh
Why it mattersJudge a blackout unit on capacity against nightly draw rather than on charge speed, and on that test the Yeti clears a multi-day outage while the RIVER 2 is not in the conversation.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Six of the seven rows end with the RIVER 2 short of the load, which is where the size gap stops being a spec and becomes a night you do not finish.
Six of the seven rows end the same way, with the RIVER 2 running out. How it runs out is the interesting part. On the CPAP night it gets about two thirds of the way, which is a worse outcome than missing by a mile, because the failure arrives at 4 a.m. rather than at bedtime. On the van-life day it covers about 5% and the question answers itself before you finish asking it.
The two rows the engine hands to nobody are the ones worth reading twice. Camping and the tailgate both need energy and a way to get it there, and between a box that goes anywhere without finishing and an appliance that finishes anything without going, there is an entire class of unit that neither of these is.
Portability & Form Factor
Selected because: 7.8 lbs against 106 lbs decides more of this page than capacity does: one unit travels, the other gets placed.
weight
The Yeti's weight is not a flaw you can shop around, it is arithmetic. 6,071Wh over 106 lbs lands near 57Wh a pound against the RIVER 2's 256Wh over 7.8 lbs, about 33. The heavy unit is the efficient one. What the small box actually sells you is the handle.
So the real question is not which is easier to carry, it is whether the thing leaves the house at all. Our record flags the 6000X as stationary, reviewers describe it as a semi-stationary hub and it ships with a roll cartB2, and 106 lbs is a two-person decision you make once. The RIVER 2 goes in the bottom of a daypack and you stop thinking about it.
What the Specs Don't Tell You
Selected because: Five cards fire here, and the two that should change what you do are a 500-cycle rating and a UPS mode that only the discontinued unit lists.
rated cycles
Five cards fire and they do not all point the same way, which is the honest shape of this matchup. Two of them favour a unit you cannot buy, since the 5-year warranty and the 3,000-cycle rating both belong to the RIVER 2. One favours nobody much, because sealed capacity on a 7.8 lb box is a description rather than a defect.
The card that should change what you do is the cycle rating. $4,000 buys 6,071Wh of lithium NMC rated for 500 cyclesB1, which works out to $1.32 for every kilowatt-hour the pack delivers across its rated life. That figure is a verdict on duty cycle rather than on the unit. Standing by for outages, the Yeti will outlast the rating by years and the number means nothing. Cycling every night, it is expensive energy, and at the end of it the pack settles to roughly 80% of the capacity you started withB4.
Growth Path
Selected because: The Yeti clears the 4,685Wh van-life day at 91% of usable capacity, so whether you plan for an expansion battery depends on how hard you intend to work it.
solar input
Expansion is the Yeti's one genuine card and it matters most to the buyer who should not stop at the base unit. The van-life day finishes at 91% of usable capacity with 475Wh left, which is a pass with nothing behind it for a cloudy Tuesday. If that is your duty cycle, a Goal Zero expansion battery belongs in the original purchase rather than in a plan for next year.
The RIVER 2 is sealed, and on a 7.8 lb box that is the product working as intended. Nobody buys 256Wh planning to grow it. Fixed capacity only counts against a unit when the ceiling it fixes you at was supposed to be the floor.
Brand Trust
Selected because: One maker has retired the unit on this page and the other's X series has gone out of stock on its own store, so where you buy matters as much as what.
EcoFlow runs the fastest release cadence in the category and the deepest range, and that cadence is why this page has a Retired tab at all. The RIVER 2 did not age out so much as get replaced in place by the RIVER 2 240.
Goal Zero's position is stranger and more worth your attention. The X series has gone out of stock across every model on Goal Zero's own store, so a new 6000X now means finding retailer stock rather than ordering from the maker, and recent support reports describe long waits and tickets sitting for weeks against a brand that built its name on premium service. None of that changes what the box does. All of it changes who you talk to when something goes wrong, so buy it somewhere with a return window you trust.
Strengths & trade-offs

Neither unit
The Yeti would run this weekend and still have 3,060Wh left over. It would also need two people to load and our record marks it stationary for good reason. The RIVER 2 goes wherever you go and covers about 10% of the 2,100Wh a weekend asks for. Neither one gives you a powered weekend, and they fail at opposite ends of the same trip.

The Yeti takes this row using 6% of itself, which tells you how badly matched these two are for a job this small. The RIVER 2 is the near miss: about two thirds of the night on 218Wh usable, with 102Wh of shortfall arriving at the worst hour available. Neither is really the right shape for medical gear anyway, because the big one lists no UPS mode and the small one's UPS has an afternoon behind it.

The RIVER 2 will start the 400W load, since 600W of surge sees to that, and then the 300W continuous rating takes over and cannot hold it. The Yeti holds it without noticing and finishes with 4,490Wh spare, but you would be wheeling 106 lbs across a parking lot to get it there. This row is the clearest picture of the gap on this page: the unit you can carry cannot do the work, and the unit that does the work cannot be carried.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Yeti 6000X
The Yeti passes at 91% of usable capacity with 475Wh left, which is a full day's work and nothing in reserve, on the one duty cycle that runs the pack every single day. That is the use where its 500-cycle rating stops being trivia. The RIVER 2 covers about 5% of the 4,685Wh day, which makes it a phone charger in this context rather than a power system.

Both cover it, and the RIVER 2 finishes at 46% used. A couple of phones and a speaker across an afternoon is the exact size of job it was built for. The Yeti covers it the way a freight elevator covers one flight of stairs. If you own a RIVER 2, this row is the argument for keeping it, and if you want this job new it is the RIVER 2 240 EcoFlow now sells for it, not the 106 lb Yeti.

Conclusion
September 19, 2026
Verdict: the Yeti 6000X, on Power Score margin
The Yeti 6000X wins because it is the only unit here you can still buy new, and because 6,071Wh does work the RIVER 2 was never built for: it covers the 1,645Wh eight-hour blackout with 3,515Wh still in hand and finishes the 4,685Wh van-life day. Confidence stops at moderate for two honest reasons. Its pack is lithium NMC rated for 500 cyclesB1, so it earns its money standing by for outages rather than cycling every night. And if you landed here wanting the RIVER 2's job, which is a laptop, some phones and a speaker at 7.8 lbs, the Yeti is the wrong answer at any price. What EcoFlow sells in the RIVER 2's place is the RIVER 2 240.

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 rates 3.9/5 (35th percentile of 24 Personal-class units), and Yeti 6000X rates 3.3/5 (1st percentile of 20 Home Backup-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Yeti 6000X: 106 lbs Is a Commitment
At 106 lbs, this is a two-person lift. Plan your placement carefully. Once it's set up, you won't want to move it. It's a semi-permanent appliance. Pick your spot.
The Expansion Question Belongs to the Yeti
A sealed 7.8 lb box is not a design failure, it is the product. Nobody buys 256Wh planning to grow it. The expansion question on this page is the Yeti's, and it is not hypothetical: the van-life day finishes at 91% of usable capacity with 475Wh left, which is a pass with nothing behind it. If you are cycling this unit daily rather than keeping it on standby, treat a Goal Zero expansion battery as part of the purchase rather than as a later upgrade.
Only the Retired Unit Lists a UPS Mode
The RIVER 2 can sit between the wall and your gear and hand over to battery when the grid drops, rated no worse than 30ms. The Yeti 6000X's spec sheet lists no UPS mode and our record carries no switchover figure for it, so we do not print one: anything plugged into it rides an outage as far as your reaction time and no further. Note which unit that favours, though. The transfer belongs to the box that has left EcoFlow's range, it is long enough that some desktops will reboot through it anyway, and with 218Wh usable behind it, it bridges a flicker rather than a night. If seamless power is what you are shopping for, neither unit on this page is it.
Five Years Against Two, and the Clock That Matters
Our records carry 5 years of cover on the RIVER 2 and 2 years on the Yeti 6000X. What makes that interesting is not the gap but what sits beside the Yeti's term: a pack rated for 500 cycles, which at daily use is spent in about 1.4 years, inside the warranty window. A cell that has reached its rated cycle count and settled at roughly 80% of original capacity is behaving as designed rather than failing, so that is not a claim you would win. Read the two-year term as cover for the things that break, and read the cycle rating as the real clock on the battery.
Battery Lifespan in Real Years
The RIVER 2 is rated for 3,000 cycles vs 500. In real life: at daily use, that's 8.2 vs 1.4 years. At weekend use (twice a week), it's 29 vs 5 years. One caution reading years across different sizes: a cycle is 256Wh on the RIVER 2 and 6,071Wh on the Yeti 6000X, so count lifetime energy — roughly 768 kWh against 3,036 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 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 Yeti 6000X works out at $1.32/kWh over its rated life. If you already own the RIVER 2, the hardware comparison still holds: over its rated life the RIVER 2 delivers about 768 kWh and the Yeti 6000X about 3,036 kWh. One caution on the lifespan row: the RIVER 2 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the Yeti 6000X still delivers more over its shorter horizon. Years measure wear, not usefulness.

Worth knowing
EcoFlow's release cadence is the fastest in the category, and it is the reason this page carries a Retired tab. The RIVER 2 did not age out of the range so much as get replaced in place by the RIVER 2 240.
Goal Zero
Ecosystem
Focused — a compact current line (6th-gen Yeti and Yeti Pro series), the previous-gen X series now out of stock across every model on Goal Zero's own store (checked 2026-09-13: 200X, 500X, 1000X, 1500X, 3000X, 6000X, some listed only as open-box), so buying one new means finding retailer stock, Sherpa power banks for the under-100Wh tier, plus Alta coolers, Nomad/Ranger solar panels, and vehicle integration kits
Support
Goal Zero built its name on premium US support out of Salt Lake City, and recent reports describe long waits, unanswered email and tickets sitting for weeks. The official community forums have been shuttered as well. The argument that a premium price buys a premium safety net is thinner than it used to be.
Community
Small but loyal — strong following in overlanding and preparedness communities. Official community forums were recently shuttered, frustrating long-time users.
App experience
Rated 4.4/5 iOS (~1,200 ratings) but recent reviews skew negative — recurring connectivity issues, crashes, and stability problems.
Unique strength
Pioneer of the portable power market — strongest brand heritage. US-based company with ruggedized, weather-resistant designs (IP ratings vary by model). Integrated "Yeti-Ready" ecosystem with coolers, lights, and vehicle kits.
Worth knowing
The previous-generation X series is out of stock across every model on Goal Zero's own store, some of it listed only as open-box, so a new 6000X now means finding retailer stock rather than ordering from the maker. Check the seller's return window as carefully as you check the spec sheet.
Analyst note
One of these makers replaced the unit on this page. The other has quietly moved past the entire series it belongs to. Neither fact changes what the two boxes do, and both change who you will be talking to if something goes wrong.
Growth path
RIVER 2
FIXED CAPACITYFixed at 256Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.

Limited ports. You'll likely need a power strip or splitter.
Yeti 6000X
EXPANDABLESupports Goal Zero expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 6,071Wh.
Accepts up to 600W of solar. Suitable for a 1-2 panel setup.
Adequate ports for most setups, but heavy users may want a power strip.
Expansion batteries are Goal Zero-specific. You're investing in the Goal Zero ecosystem.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Growth only counts if you can still buy in, and the RIVER 2 is no longer sold (EcoFlow points owners to the RIVER 2 240). That leaves the Yeti 6000X: it starts at 6,071Wh and takes Goal Zero expansion batteries, so the ceiling moves if your needs do. The RIVER 2's fixed 256Wh still matters if you already own one, but it isn't a reason to pick it over the Yeti 6000X.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 2
The RIVER 2's file is thin and mostly comparative. What exists is review-site coverage measuring it against the newer RIVER 3 rather than long-term owner reportsA0. The consistent read is that this is the older, less refined unit on the same core platform, carrying over the 300W output, the LiFePO4 chemistry and the roughly hour-long fast chargeA2, but running noticeably louder under load and going without the RIVER 3's waterproofing and faster UPSA1A3.
The recommendation that coverage lands on is narrow and worth repeating: indoor use, where every dollar countsA3. Nothing in the file contradicts the specs on this page, and nothing in it makes the unit bigger than it is.
“Shares the same core platform as the RIVER 3 — 300W output, LiFePO4 chemistry, and roughly 60-minute fast charging — and remains a popular, proven budget small-format unit.”

Goal Zero Yeti 6000X
Coverage of the 6000X is unanimous on the number that matters. It is lithium NMC rated for 500 cycles to 80%, which reviewers call out as a structural disadvantage against modern LFP packsB0B1, and they put a figure on the far end of it: a 6,071Wh pack that effectively becomes about 4,857WhB4.
The other two recurring notes are physical. It weighs about 106 lbs, is described as a semi-stationary hub and arrives with a roll cartB2. And it carries a 2,000W pure sine inverter peaking to 3,500W with a full refill in 12 hours from the included 600W AC chargerB3. Twelve hours is most of the daylight in a two-day outage, which is worth knowing before you plan to run the unit down to empty on the first night.
“Weighs about 106 lbs — not portable for most people; designed as a semi-stationary power hub, and comes with a roll cart.”

“Weighs about 106 lbs — not portable for most people; designed as a semi-stationary power hub, and comes with a roll cart.”

“A 2,000W pure sine inverter peaking to 3,500W, fully rechargeable in 12 hours with the included 600W AC charger.”

“After 500 cycles capacity drops to ~80%, so the 6,071Wh battery effectively becomes ~4,857Wh — a structural NMC disadvantage vs LFP.”

Who Should Buy Which
Buy the RIVER 2 if you…
- →You already own one. It is still a 3,000-cycle pack in a 7.8 lb box, and the afternoon row on this page, phones and a speaker across 100Wh, is the work it was built for.
- →You own one and want its best remaining job: sitting between the wall and a router so the modem does not blink. The listed UPS mode is rated no worse than 30ms and there is 218Wh behind it, which rides out a flicker rather than a night.
- →You want that job new rather than second-hand. The unit to look at is the RIVER 2 240, which EcoFlow sells in the RIVER 2's place. Its numbers are not on this page, so we do not quote them here.
Buy the Yeti 6000X if you…
- →You want a backup that lives in a garage or a basement and waits. 6,071Wh covers the 1,645Wh eight-hour blackout with 3,515Wh spare, and 2,000W continuous with 3,500W of surge starts and holds what a kitchen puts in front of it.
- →You are off-grid daily and prepared to feed it 600W of solar, in which case treat the expansion battery as part of the purchase, because the 500-cycle ratingB1 is a countdown for anyone cycling it every night.
- →You have already picked the spot. 106 lbs is a two-person lift and a decision you want to make once, not one you want to revisit when the furniture moves.
If neither fits
Anyone who needs power that travels and lasts, which is most people who open a page like this, and the reason two scenario rows here end with nobody winning. The RIVER 2 goes anywhere and covers about 10% of a camping weekend's 2,100Wh; the Yeti covers the weekend twice over and weighs 106 lbs. Look at the middle of the range instead, at a unit sized to finish that 2,100Wh weekend while staying light enough for one person to lift into a car. Skip both as well if what you want is an uninterrupted night for medical gear: the Yeti's record lists no UPS mode at all, and the RIVER 2's UPS has an afternoon of capacity behind it rather than a night.
The Bottom Line
The Yeti 6000X takes this because it is the only one of the two you can buy new, and because 6,071Wh does a job the RIVER 2 was never asked to do. Buy it for what it is, an appliance that gets wheeled into a corner and waits, with the capacity to carry a blackout and the surge to start what is in your kitchen. Cycle it every night and you are spending a 500-cycle pack quicklyB1. Leave it standing by and that rating is close to beside the point.
And if you came here for the small box, a laptop and some phones and a speaker at 7.8 lbs in the bottom of a bag, do not let this verdict talk you into 106 lbs of appliance. That job is real, the RIVER 2 did it well, and the RIVER 2 240 is what EcoFlow sells for it now. The Yeti is the answer to a different question, asked by someone with a basement.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow RIVER 2 discontinued?
Yes. It has left EcoFlow's range and this page shows no price for it. EcoFlow sells the RIVER 2 240 in its place. If you already own a RIVER 2 nothing about it has changed, and the specs on this page are still its specs, but buying one new now means finding retailer stock.
Can the EcoFlow RIVER 2 run a CPAP all night?
No. The overnight profile asks for 320Wh and the RIVER 2 holds about 218Wh usable once nameplate capacity is cut by the flat 85% derate, so it covers roughly two thirds of the night and stops 102Wh short. It is a good afternoon unit and a fine router bridge, not a machine to sleep next to expecting morning.
Does the Goal Zero Yeti 6000X have a UPS mode?
Our record carries no switchover figure for it and its spec sheet lists no UPS mode, so we do not print one. In practice, gear plugged into the Yeti is not protected at the moment the grid drops. You get power back as fast as you can walk over and plug in. The RIVER 2 is the unit with a listed UPS mode here, rated no worse than 30ms, and even that is a long enough transfer that some desktops will reboot through it.
Is the Goal Zero Yeti 6000X worth the money?
As standby power, yes. As a daily driver, no. It is rated for 500 cycles, so cycling it every night spends the pack's rated life inside a couple of years and leaves you at about 80% of original capacity. Parked in a basement waiting for outages, that rating will never be the thing that limits you, and 6,071Wh with 2,000W of continuous output is a lot of blackout for one appliance.
What should I buy if I want something between these two?
Something in the middle of the range, big enough to finish the 2,100Wh camping weekend and light enough that one person can put it in a car. Both rows on this page that end with nobody winning fail for opposite reasons: the RIVER 2 travels and cannot finish, the Yeti finishes and cannot travel. The gap between 256Wh and 6,071Wh is where most buyers actually live.
