Spec deltas
The RIVER 3 wins this on arithmetic, not on features. It's $199 against $350, 7.8 lb against 13.7, and it comes up short on exactly the same list of jobs the Yeti comes up short on. That list is all of them.
Start with the smallest job on the page. A CPAP night draws 320Wh. The RIVER 3 holds 245Wh and the Yeti 297Wh, and after inverter losses you keep roughly 85% of either, so 208Wh and 252Wh actually reach the socket. Both machines stop before your alarm does. The Yeti gets further into the night and still doesn't reach morning, and that same pattern repeats through camping, blackouts, a remote workday, and van life.
There is one thing the extra money genuinely buys, and it isn't capacity. The Yeti accepts 200W of solar against the RIVER 3's 110W, which is the difference between refilling a whole pack in about an hour and a half of strong sun and taking a bit over two hours to refill a smaller one. If you're pairing this with panels, read the solar chain below before you take the cheap advice. If you're charging from a wall outlet like most people at this size, note that both units hand off in 20ms, so even the UPS question comes back a tie, and you're left comparing a $199 box to a $350 one.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Now add the fact that $199 is the entire price of a RIVER 3, not a rounding error on it. Two of them run $398 and hold 490Wh, which is $48 more than one Yeti for 193Wh more energy, split across two boxes you can put in two rooms. One on the CPAP, one on the router, and neither of them is the one you have to go unplug at 2 a.m.
RIVER 3: $199 for 245WhYeti 300: $350 for 297WhThe gap between them is $151 for 52Wh
Why it mattersIf your real complaint is that there aren't enough watt-hours here, stop comparing these two and buy two of the cheap one.
On the tailgate load the battery isn't even the binding constraint. Both units surge to 600W, neither can start the peak draw, and the larger pack behind it buys precisely nothing. What the extra money purchases everywhere else is the same thing it purchases there: a smaller gap, not a crossed line.
All six scenarios return 'neither' for both unitsThe CPAP night needs 320Wh against roughly 208Wh and 252Wh of usable energyThe Tailgate peak exceeds both units' 600W surge ceiling
Why it mattersIf one of those six is the reason you're shopping, neither box is the answer. Go up to a unit rated at least twice what these hold and come back to this size later.
solar input
That combination describes one specific buyer. Set the Yeti beside a panel at a fixed camp and its 5.9 lb weight penalty is a one-time toll you pay walking from the truck, while the solar advantage pays out every morning you're there. Reverse the trip and the logic reverses with it: if the box moves more than it sits, you're hauling nearly twice the weight for a charging speed you never once use.
Yeti 300 accepts 200W solar input; RIVER 3 accepts 110WYeti holds 297Wh; RIVER 3 holds 245WhYeti weighs 13.7 lb; RIVER 3 weighs 7.8 lb
Why it mattersOwn a 200W panel and stay put for a few days? Pay the $151. Charge from the wall and move the box a lot? Don't.
cost / lifetime kWh
Two cents is a rounding error, and that's the point. The strongest long-horizon case for the expensive box ends in a draw. Both carry the same five-year warranty, and daily cycling puts the RIVER 3 at 8.2 years and the Yeti at 11, so what you're being asked to fund today is years nine through eleven of a 297Wh unit's life.
Yeti: 4,000 cycles. RIVER 3: 3,000Lifetime delivery: 1,188 kWh versus 735 kWhCost per lifetime kWh: $0.29 for the Yeti, $0.27 for the RIVER 3
Why it mattersDon't let the cycle count decide this. It's the Yeti's best-looking spec and its weakest argument.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: All six loads we test come back as 'neither,' which changes the question from who wins to whether either belongs on your list.
Six scenarios, six 'neither' verdicts, and that's the most useful line on the page. These are 245Wh and 297Wh boxes dropped into a test suite whose smallest load is a 320Wh CPAP night and whose largest is a 4,685Wh van-life day. Nobody should read this grid and conclude the Yeti came close. It landed less far away.
What these two are actually good at doesn't show up here, because it's too easy to score: phones, a laptop, camera batteries, a router and modem through an evening outage, a CPAP for part of a night if you can top it off in the car come morning. Both do all of that without complaint. One does it for less money.
Lifetime Value
Selected because: $0.27 against $0.29 per lifetime kWh is a tie; the $151 you hand over on day one is not.
cost / lifetime kWh
Two cents a kilowatt-hour separates these across their entire service lives, which is another way of saying nothing does. The Yeti earns its number honestly. 4,000 cycles on a 297Wh pack works out to 1,188 kWh of lifetime delivery against the RIVER 3's 735 kWh, and it spends every bit of that advantage covering its own sticker.
Where the gap is real is the part you pay before any of that starts. The long-run math is a draw and the day-one math isn't, and a draw ten years out is a poor reason to fund a difference today.
Portability & Form Factor
Selected because: 7.8 lb against 13.7 is the widest proportional gap between these two, and the one you feel every time the unit moves.
weight
5.9 lb doesn't sound like much until you notice it's 76% more box for 21% more energy. The RIVER 3 at 7.8 lb is a one-hand, one-trip pickup, the kind of thing you carry out to the car without planning the trip. The Yeti at 13.7 is the one you set down halfway to the campsite and reconsider.
Weight is also why the solar argument cuts both ways. The unit that most rewards being left in one place next to a panel is the same unit that punishes you for carrying it, and at this size most people are carrying it.
What the Specs Don't Tell You
Selected because: One of these publishes a noise figure and one doesn't, which matters when a 245Wh box usually lives on a desk or next to a bed.
rated cycles
EcoFlow publishes a noise figure for the RIVER 3 and Goal Zero publishes none for the Yeti 300. That isn't evidence the Yeti is loud. It's evidence about which company expected you to ask, and at 245Wh to 297Wh these units live on desks and nightstands where the answer matters more than the capacity does.
The cycle-life card goes to the Yeti and the warranty card is a draw at five years each. Read those two together and you get a pair of units that will both outlast their coverage by years, sold at very different prices for the privilege.
Brand Trust
Selected because: Support quality is the one thing you can't read off a spec sheet, and both of these brands have specific problems with it.
Goal Zero's premium price used to arrive with premium support, and that's the part of the pitch under strain. Response times have slipped from days into weeks and the official community forums have been shuttered, which is a strange move for a brand whose loyal overlanding following was half of what you were buying. The heritage is genuine. The service that justified the markup is thinner than it was.
EcoFlow's counterweight is not a clean sheet. Its support experiences are polarized, it walked back an attempt to paywall app features after a backlash, and it recalled the DELTA Max 2000 in October 2025 over an overheating risk. Different product line, different pack, but you should know it before deciding the cheaper brand is automatically the safer one. What EcoFlow does bring at this size is scale: a subreddit around 31,000 members and a 4.6/5 iOS app mean the answer to your weird 2 a.m. question probably already exists somewhere.

Scenario verdicts
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 full camping weekend asks for 2,100Wh and the larger of these two holds 297Wh, so neither is your camp's power supply. What both do well is the job people actually bring this size for: phones, lights, a laptop, and camera batteries kept alive between drives.
Battery budget usedlower = more headroom
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
Eight hours of outage wants 1,645Wh. These hold 245Wh and 297Wh. Both are modem-and-lamp boxes for a blackout rather than house boxes, and neither gets closer to the real number than the other in any way that matters.
Battery budget usedlower = more headroom
LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Neither unit
This is the closest either one comes, and neither one arrives. A 320Wh night against roughly 208Wh and 252Wh of usable energy means the machine stops before you wake up, with the Yeti simply getting further into the dark. If a CPAP is why you opened this page, it's the page telling you to shop a size up.
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
Neither unit covers this scenario's 910Wh: the RIVER 3 comes up 702Wh short (about 23% covered), the Yeti 300 658Wh (28%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.
Battery budget usedlower = more headroom
LOAD Laptop 60W×8h · External Monitor 30W×8h · Router + Modem 20W×8h · Phone Charger 15W×2h
SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Neither unit
Neither one starts the party. This is the scenario where the battery isn't the problem: the peak draw sits above both units' 600W surge ceiling, so the size of the pack behind it is irrelevant. Blenders and warming trays want a bigger inverter than either box has.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit covers this scenario's 4,685Wh: the RIVER 3 comes up 4,477Wh short (about 4% covered), the Yeti 300 4,433Wh (5%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Afternoon Off-Grid
Phones and a speaker at the park, beach, or campsite — the small-unit job description
Either unit
This is the job small stations are actually for, and both do it: the RIVER 3 finishes at 48% used, the Yeti 300 at 40%. At this size the decider is what rides in the bag — 7.8 lbs for the RIVER 3 against 13.7 for the Yeti 300 — and price, not the leftover watt-hours.

Conclusion
August 2, 2026
Verdict: the EcoFlow RIVER 3
Buy the RIVER 3 at $199. The Yeti 300's advantages are real and none of them changes an outcome: its 297Wh loses the same six jobs the RIVER 3's 245Wh loses, its 4,000 cycles are already priced into a lifetime cost it still doesn't win, and it asks you to carry 13.7 lb where the RIVER 3 asks for 7.8. The one genuine exception is solar. The Yeti takes 200W of panel against 110W, so if the plan is to park it beside an array and refill from the sun rather than the wall, the extra money buys something you'll feel every day of the trip. Everyone else is paying $2.90 for each of the Yeti's 52 extra watt-hours, on a shelf where the RIVER 3 sells its own for 81 cents.

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 4.4/5 (67th percentile of 22 Personal-class units), and Yeti 300 rates 3.7/5 (24th percentile of 22 Personal-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Same five years, different price per year
Both brands cover you for five years, so the paperwork is a wash. What isn't is the cost of those years: $40 annually on the RIVER 3, $70 on the Yeti, for identical coverage terms on units that will both still be working when the coverage lapses.
The Yeti wins this one cleanly
4,000 cycles against 3,000, or about 11 years of daily cycling versus 8.2. That's a genuine engineering advantage and it's worth saying plainly. It's also years nine through eleven of a small power station's life, comfortably past the five-year warranty and past the point where most people replace a unit this size for reasons that have nothing to do with the cells.
One brand published a number, one didn't
EcoFlow rates the RIVER 3 under 30 dB. Goal Zero doesn't publish a figure for the Yeti 300 at all. That's not proof it's loud, and plenty of quiet units go unrated. But a 297Wh box spends most of its life on a desk or a nightstand, which is exactly where an undisclosed fan is a question you'd rather have answered before purchase than at 2 a.m.

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 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 recalled the DELTA Max 2000 in October 2025 over an overheating risk, and it tested app-feature paywalls in early 2025 before backing off. Different product line, different pack, but worth knowing before you file the cheaper brand under 'safer.' Support experiences run polarized: many hassle-free prepaid-label replacements, and a meaningful number of long waits.
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
US-based company (Salt Lake City, owned by NRG Energy). Historically considered premium support, but 2025-2026 reports describe long wait times, unresponsive email communication, and tickets going unaddressed for weeks. The "premium support justifies premium pricing" argument is weakening.
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
Goal Zero built this market, and it shows in the hardware. US-based, ruggedized, IPX4-rated, and slotted into a coherent Yeti-Ready ecosystem of coolers, lights, and vehicle kits that nobody else quite matches for overlanding.
Worth knowing
The premium-support argument that justified premium pricing has weakened. Ticket response has stretched into weeks and the official community forums were shuttered, which stings most for the long-time owners who were the brand's best asset.
Analyst note
One brand is the pioneer with the stronger build story and the weakening service record. The other is the scale player with a deeper catalog, a much larger community to answer your question, and a recall on its record. Neither profile is clean enough to override a $151 price gap on units this small, so let the hardware decide and treat the brand column as a tiebreak you didn't need.
Growth path
RIVER 3
FIXED CAPACITYFixed at 245Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 110W of solar. Limited to a single portable panel.
Limited ports. You'll likely need a power strip or splitter.
Yeti 300
FIXED CAPACITYFixed at 297Wh, 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.
Adequate ports for most setups, but heavy users may want a power strip.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Neither expands, and that's no knock on either — each is a complete unit at a fixed size. Buy the capacity that covers your needs now (the Yeti 300 gives you the larger ceiling); you can't add to either later.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 3
Field material on the RIVER 3 is thin and mostly comparative. What exists comes from review sites weighing it against the RIVER 2 rather than from owners a year deepA1A3. That coverage is at least consistent: sub-30 dB operation is singled out as the headline improvementA1, with IP54 sealing, a faster handoff, and a lighter body stacked on topA2A4. Reviewers land on it as the better buy for camping, van life, and desk-side backupA3. Directional and useful, but not the same thing as two winters of owner reports.
“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.”

Goal Zero Yeti 300
The Yeti 300's coverage is more specific and more mixed. The build draws steady praise: rubberized corners, a sturdy handle, IP54 sealing, and a 0-100% recharge in 50 minutesB2, wrapped around a modern LFP pack rated past 4,000 cyclesB1. The caveats are just as steady. One reviewer watched it shut down two minutes into brewing coffee near its output ceilingB3, and the recurring note is that you're paying a lot for 297WhB3B4.
Nobody in the ledger calls it a bad unit. Several call it an expensive oneB3B4, which is the same conclusion the price tag reaches on its own.

Who Should Buy Which
Buy the RIVER 3 if you…
- →The unit lives in a closet and comes out for weekends. You charge from a wall outlet, you carry it to the car yourself, and the number that decides your Saturday is 7.8 lb, not 52 watt-hours.
- →It's going next to your bed or under your desk. EcoFlow publishes sub-30 dB for the RIVER 3A1, and it's the only one of these two with a published figure at all.
- →You want backup for a router, a modem, a laptop, and phones through an evening outage. Both units handle that identically, down to the same 20ms handoff, so the only remaining variable is what you paid.
Buy the Yeti 300 if you…
- →You already own a 200W panel and a campsite you don't move for three days. This is the one buyer for whom the price difference converts into something you use every morning.
- →It's riding in a truck bed and getting cycled daily for a decade. 4,000 cycles and the IP54, rubberized-corner buildB2 are exactly what the premium is for.
- →You have one specific device that draws between 300W and 350W continuous. That's a narrow window and the Yeti is the only one of these that fits it, though a reviewer did have it quit two minutes into a coffee maker near that ceilingB3, so don't plan to live at the limit.
If neither fits
Your list starts with a fridge, a full CPAP night, or a day of working out of a truck. 320Wh is the smallest load on this page and neither box clears it, so shopping these two is choosing between two wrong answers. Look at units rated at least twice what these hold, and come back to this size later if you want a second, smaller box for another room.
The Bottom Line
Take the RIVER 3 at $199. Its 52-watt-hour deficit costs it nothing you can point to: the same six jobs defeat both units, the Yeti's extra cycles get spent covering its own sticker, and what stays in your pocket is $151 and 5.9 lb you don't carry.
The one honest reason to pay more sits in the solar numbers. 200W of panel input against 110W is real, it's daily, and it belongs to whoever charges from the sun at a camp they don't move. If that isn't you, every Yeti advantage is a number that never becomes an outcome. Buy the light one.

For most uses at this size, no. The Yeti gives you 52 more watt-hours, 1,000 more cycles, and 50 more watts of continuous output, and none of that changes what the unit can finish. The exception is solar: 200W of panel input against 110W is a real daily advantage if you refill from the sun instead of a wall socket.
Can the RIVER 3 or the Yeti 300 run a CPAP all night?
Neither one reliably. A CPAP night runs about 320Wh, and after inverter losses these deliver roughly 208Wh and 252Wh, so both get you most of the way and quit before morning. Adding a heated humidifier makes it worse. If a CPAP is why you're shopping, you want a unit rated well above 376Wh, which is 320 divided by the 85% you actually get to use.
Which is better for solar charging, the RIVER 3 or the Yeti 300?
The Yeti 300, clearly. It accepts 200W of panel input against the RIVER 3's 110W, and because it also holds more, its 297Wh refills in roughly an hour and a half of strong sun while the RIVER 3's 245Wh at 110W takes a bit over two. Real sun underperforms rated input for both units, but the ranking doesn't move.
Do these work as a UPS for a desktop, router, or modem?
Both do, and they do it equally. Each hands off in 20ms, quick enough that a desktop, a modem, or a router won't register the outage at all. The only difference is how long it holds afterward, and 52Wh isn't much of a difference. Decide this one on price.
Which one lasts longer?
The Yeti, on paper: 4,000 cycles against 3,000, which is 11 years of daily cycling versus 8.2. Both carry the same five-year warranty and both will outlive it comfortably. Spread across their full lives the cost lands at $0.29 per kilowatt-hour for the Yeti and $0.27 for the RIVER 3, so the longer life doesn't make it the cheaper unit to own.
