EcoFlow RIVER 3 MAX vs Goal Zero Yeti 300
The RIVER 3 MAX costs less than the Yeti 300 and gives you nearly double the capacity, double the output, a lighter carry, and a growth path, so the only reason to look at the Yeti is if you'll refill from solar and nothing else.

Spec deltas
The RIVER 3 MAX is cheaper than the Yeti 300 and holds nearly twice as much. It costs $319 against $349.95, stores 572Wh against 297Wh, and outputs 600W continuous against 350W. It's also lighter, at 10.4 lbs to 13.7, and it can expand past its base where the Yeti is sealed shut. The composite score isn't subtle about it: 2472 to 1602.
The Yeti 300 isn't a bad unit; it's just out-specced at a higher price. It runs modern LiFePO4 cells rated for 4,000 cycles, a third more than the RIVER's 3,000, and it's rugged and well-built. But both units last well over a decade, so that cycle lead is a number few owners will ever cash in.
The Yeti's one edge you can actually use is solar. Its 200W input refills its 297Wh battery quickly, while the RIVER's 110W ceiling takes about 7.4 hours to fill its larger pack. If you charge from panels and never touch a wall outlet, that matters. For everyone else, the RIVER is cheaper to buy, cheaper to run, bigger, lighter, and able to grow.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
cost / lifetime kWh
The RIVER gives you nearly double the capacity for about $31 less up front, then delivers each kWh cheaper for years. There's no capacity-per-dollar argument left for the Yeti to make.
The RIVER 3 MAX costs $319 and holds 572Wh; the Yeti 300 costs $349.95 and holds 297WhCost per lifetime kWh is $0.19 for the RIVER and $0.29 for the Yeti
Why it mattersAny buyer choosing on value should stop here and take the RIVER; the Yeti has to win on something other than price or size, because it loses both.
solar input
This is the Yeti's one usable advantage, and it only appears off-grid. Refill from a wall outlet and it vanishes, because the RIVER charges fast from AC; the gap exists solely for a buyer whose only power source is panels.
The Yeti 300's solar input ceiling is 200W; the RIVER 3 MAX's is 110WThe RIVER's larger 572Wh battery takes about 7.4 hours to refill from its 110W solar ceiling
Why it mattersIf you camp or live off solar alone and value a quick daytime top-up, weight the Yeti's 200W input; if you'll ever plug into a wall, it's irrelevant.
rated cycles
The Yeti's 4,000 cycles beat the RIVER's 3,000 on paper, but both translate to well over a decade of use, so the difference is capacity you'll never reach. Meanwhile the RIVER's output, weight, and expansion are advantages you feel the first week.
The RIVER 3 MAX outputs 600W continuous with a 1,200W surge, weighs 10.4 lbs, and expands past its 572Wh base; the Yeti 300 outputs 350W with a 600W surge, weighs 13.7 lbs, and is sealedThe Yeti is rated for 4,000 cycles against the RIVER's 3,000
Why it mattersBuyers weighing real, usable differences should take the RIVER; the Yeti's cycle lead is the kind of spec that wins arguments and loses purchases.
The specific dimensions that decide these two units — everything else is a tie.
PowerScore Breakdown
Selected because: The 2472-vs-1602 gap is the widest signal on the page and frames the blowout.
overall power score
The composite is 2472 for the RIVER against 1602 for the Yeti, one of the wider gaps you'll see between two units in the same size class. It isn't one category doing the work; the RIVER leads on capacity, output, surge, weight, expansion, and price all at once, and the score adds them up.
The Yeti's contributions to the score are cycle life and solar input, and neither is enough to close 870 points. When a cheaper unit outscores a pricier one by this margin, the composite is telling you the matchup is lopsided, not tight.
Lifetime Value
Selected because: The RIVER is both cheaper up front and cheaper per lifetime kWh; the value case is decisive.
cost / lifetime kWh
The RIVER delivers energy at $0.19 per lifetime kWh against the Yeti's $0.29, and it does that while costing less to buy. The usual tradeoff, a lower sticker in exchange for higher running cost, or the reverse, simply doesn't exist here; the RIVER is cheaper on both axes.
The Yeti's cost story leans entirely on its 4,000-cycle rating, which is genuinely higher than the RIVER's 3,000. But the RIVER's near-double capacity means it moves more energy per charge, so even with fewer cycles its lifetime cost lands lower. Cheaper box, cheaper energy, and it isn't close.
What the Specs Don't Tell You
Selected because: Solar recharge is the Yeti's one real counter and expansion is its flagged gap; both live here.
rated cycles
The card worth reading twice is solar recharge, and it's the Yeti's, not the RIVER's. The RIVER's 110W solar ceiling takes about 7.4 hours to refill its 572Wh battery, while the Yeti's 200W input tops off its smaller pack far quicker. If you live off panels, that's the one place the Yeti earns its price. Naming it is only fair, since everything else on this page runs the RIVER's way.
The expansion card runs back the other direction: the Yeti is a sealed 297Wh box the engine flags as having no growth path, while the RIVER can add battery past its base. And the Yeti publishes no noise figure at all, where the RIVER discloses a quiet 30dB under load, so on sound you're comparing a known quantity to an unknown one.
Growth Path
Selected because: The RIVER expands and the Yeti can't, a structural difference worth its own section.
solar input
The RIVER expands past its 572Wh base with EcoFlow add-on batteries, so a purchase that starts as a light-duty unit can grow toward longer trips or partial backup without being replaced. The Yeti 300 offers no such path; outgrow 297Wh and your only option is a new unit.
As always, expansion only counts if you'll use it. But paired with the RIVER already holding nearly double the Yeti's capacity out of the box, it means the RIVER starts ahead and can pull further ahead, while the Yeti starts behind and stays there.
Brand Trust
Selected because: Cross-brand pair with genuinely different ecosystem, innovation cadence, and support tradeoffs.
EcoFlow runs the largest lineup and the most active innovation cadence in portable power, with fast X-Stream charging and modular expansion that scales far past anything in this class. Its app is among the best-rated in the category. The caveats are worth knowing: an October 2025 recall on a different unit, and a brief 2025 experiment with app paywalls that community pushback paused.
Goal Zero is the US-based pioneer with rugged, weather-resistant designs and a loyal preparedness following. The honest caveat is that it's the priciest brand per watt-hour, its once-premium support has slipped in recent reports, and it's seen as slower to innovate than faster-moving rivals. On this pair that pattern shows: the newer EcoFlow simply offers more for less.

Conclusion
July 16, 2026
Verdict: the RIVER 3 MAX
This one isn't close on the big numbers. The RIVER 3 MAX costs $319 against the Yeti 300's $349.95 and still gives you 572Wh to the Yeti's 297Wh, 600W output to 350W, a 10.4-lb carry to 13.7, an expansion path the sealed Yeti lacks, and a quieter 30dB under load. Over its life it delivers energy at $0.19 per kWh against $0.29. The engine's composite reflects all of it: 2472 to 1602. The Yeti keeps two honest cards: it's rated for 4,000 cycles to the RIVER's 3,000, and its 200W solar ceiling refills its smaller battery far faster than the RIVER's 110W does. The cycle edge is unreachable for most owners since both last a decade-plus; the solar edge is real but only if you charge off panels alone. For nearly everyone, the cheaper, bigger, lighter, expandable unit wins.

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 rates 4.7/5 (83rd percentile of 19 Compact-class units), and Yeti 300 rates 4.0/5 (43rd percentile of 22 Personal-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
7.4 Hours of Sun on the RIVER, and the Yeti's One Win
The RIVER's 110W solar ceiling needs about 7.4 hours to refill its 572Wh battery, and the Yeti's 200W input tops off its smaller pack noticeably faster. This is the single spec where the Yeti beats the RIVER, and it only matters off-grid. Plug into a wall and the RIVER's fast AC charging erases it.
The RIVER Can Grow, the Yeti Can't
The Yeti 300 is a sealed 297Wh box; outgrow it and you buy a new unit. The RIVER 3 MAX adds battery past its 572Wh base. It already holds nearly double the Yeti out of the gate, so it starts ahead and can pull further ahead.
Same 5 Years, Lower Cost on the RIVER
Both carry 5-year warranties, so coverage is a wash. Because the RIVER costs less, its cost per warranty year comes in lower, $64 against the Yeti's $70. A small edge, but it points the same way as everything else.
4,000 Cycles vs 3,000, Both Unreachable
The Yeti's LiFePO4 pack is rated for 4,000 cycles to the RIVER's 3,000, a genuine edge on paper. But both translate to well over a decade of use, so it's capacity most owners will never spend. Nice to have, rarely decisive.
No Noise Number on the Yeti
The Yeti 300 publishes no noise figure, while the RIVER discloses a quiet 30dB under load. That's a known quantity against an unknown one, not proof the Yeti is louder, but a reason not to assume it's quieter.

Analyst note
EcoFlow's edge is doing more for less with a deeper, faster-moving lineup; Goal Zero's is heritage and rugged US-brand build. On this pair the gap is unusually one-sided: the RIVER is cheaper, bigger, lighter, and expandable, and the Yeti's answers are a cycle rating you won't exhaust and a solar ceiling that only helps off-grid. Support has been inconsistent on both sides lately, so research your specific model's recent track record either way.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 3 MAX
The RIVER 3 MAX's field reputation starts with how little you notice it. It's built on the RIVER 3 platform reviewers praise for sub-30dB whisper-quiet operation and an IP54 rating for dust and water, which is what you want in a unit that might sit next to you at a campsite or a deskA2. Its LiFePO4 cells are rated for 3,000-plus cycles to 80%, roughly a decade of everyday useA3.
It's also the capacity leader of its line and a genuinely portable one, which reviewers value for people who don't need to power a whole houseA1. Coverage of the specific MAX model is a little thinner than the platform as a whole, but the RIVER 3 family earns consistent marks for quality engineering and real portabilityA4.

Goal Zero Yeti 300
The Yeti 300's most-cited knock is the one that bites hardest against a cheaper, bigger rival: the price stings for the capacity you get, and the 297Wh ceiling keeps it to light duty, roughly 4-6 hours on a laptop or 20-30 phone chargesB4B3. One test saw it shut down after two minutes when a coffee maker pushed it near its 300W limitB3.
What it does well is last and endure. Its 297Wh LiFePO4 pack is rated for 4,000-plus cycles, over a decade of daily use, with a 200W pure sine inverterB1, and the build earns praise: just over 12 lbs, an IP54 rating, rubberized corners, a sturdy handle, and a 0-100% recharge in about 50 minutesB2. It's a well-made small unit; here it's simply out-specced at a higher price.

Who Should Buy Which
Buy the RIVER 3 MAX if you…
- →You want the most capacity and output per dollar, full stop; the RIVER holds nearly double the Yeti at a lower price and starts bigger loads with its 600W output.
- →You value a light, quiet unit that can grow, at 10.4 lbs and 30dB with an expansion path, it's the easier carry now and the more flexible buy later.
Buy the Yeti 300 if you…
- →You charge exclusively from solar and want the fastest daytime top-up; the Yeti's 200W input refills its smaller battery quicker than the RIVER's 110W ceiling manages.
- →You specifically want the higher cycle rating and Goal Zero's rugged, US-brand build, and you're willing to pay more for less capacity to get it.
If neither fits
If the real job is weekend camping (about 2,100Wh) or an 8-hour blackout across several appliances (about 1,645Wh), neither unit covers it alone, though the RIVER can be expanded toward it and the Yeti can't. For those loads out of the box, step up to a 1,000Wh-plus unit.
The Bottom Line
The RIVER 3 MAX wins this on the numbers that matter most: it costs less than the Yeti 300, holds nearly double the capacity, outputs almost twice the watts, weighs less, expands, and still delivers energy cheaper over its life. The composite score's 870-point gap isn't noise; it's the sum of the RIVER leading in category after category.
The Yeti 300 keeps two honest cards, a higher cycle rating and a faster solar ceiling, but the first is a number few owners reach and the second only helps if you charge off panels alone. Buy the Yeti if you're solar-only and want that quick top-up. For everyone else, the cheaper, bigger, lighter, expandable RIVER is the clear call.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
EcoFlow RIVER 3 MAX or Goal Zero Yeti 300, which should I buy?
The RIVER 3 MAX for nearly everyone. It costs less ($319 vs $349.95), holds almost double the capacity (572Wh vs 297Wh), outputs 600W to the Yeti's 350W, weighs less, and can expand. The Yeti only makes sense if you charge from solar alone and want its faster 200W input.
Is the Yeti 300 better made than the RIVER 3 MAX?
Both are rugged IP54-rated LiFePO4 units, so build isn't the deciding factor. The Yeti's edge is a higher cycle rating, 4,000 against 3,000, but both last well over a decade, so that gap rarely matters in practice. The RIVER answers with more capacity, more output, less weight, and a lower price.
Which charges faster from solar?
The Yeti 300, and it's its main advantage. Its 200W solar ceiling refills its 297Wh battery quickly, while the RIVER 3 MAX's 110W input takes about 7.4 hours to fill its larger 572Wh pack. If you rely on panels rather than a wall outlet, that's a real point in the Yeti's favor.
Is the RIVER 3 MAX really cheaper and bigger at the same time?
Yes. It lists at $319 against the Yeti 300's $349.95 while holding 572Wh to the Yeti's 297Wh. That combination is unusual, and it's why the RIVER also comes out cheaper per lifetime kWh, $0.19 against $0.29.
Can I expand either of these later?
Only the RIVER 3 MAX. It accepts EcoFlow add-on batteries to grow past its 572Wh base, while the Yeti 300 is a sealed unit, so outgrowing its 297Wh means buying a whole new station. If there's any chance your needs climb, that flexibility favors the RIVER.
