Head-to-head test
EcoFlow RIVER 2 Pro vs Goal Zero Yeti 700
Goal Zero charges $200 more for 91Wh less capacity and 200W less output — the only things that money buys are 1,000 extra charge cycles and a 20ms-faster switchover, and neither closes the price gap.

Spec deltas
The Goal Zero Yeti 700 costs $699.95 against the EcoFlow RIVER 2 Pro's $499 — a $200.95 gap — while holding 91Wh less capacity and delivering 200W less continuous output. On paper, the more expensive unit is the smaller, weaker one.
Goal Zero's answer is longevity and switchover speed: the Yeti's LiFePO4 cells are rated for 4,000 cycles against the RIVER 2 Pro's 3,000, and its 10ms line-interactive switchover beats the RIVER 2 Pro's 30ms by a wide margin. Both are real engineering choices, not marketing filler.
Run the lifetime math and the extra cycles don't pay for the extra dollars: the RIVER 2 Pro works out to $0.22 per lifetime kWh against the Yeti's $0.26. The cheaper, more powerful unit is also the cheaper one to own over its full life.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
The justification Goal Zero offers is 1,000 additional charge cycles (4,000 vs 3,000) and a faster switchover — real, but neither adds usable capacity today, and the engine's lifetime-cost math shows the RIVER 2 Pro still comes out cheaper per kWh delivered even after accounting for the Yeti's longer cycle life.
The Yeti 700 costs $699.95 against the RIVER 2 Pro's $499The Yeti holds 677Wh against the RIVER 2 Pro's 768Wh — 91Wh less
Why it mattersBuyers should treat the Yeti's price premium as paying for a decade-plus ownership horizon, not for more power today — if that's not the actual plan, the premium doesn't pay off.
continuous output
A fridge or window-unit compressor can spike 2-3x its rated draw for a moment at startup. A 1,000W surge ceiling gives less room to absorb that spike than a 1,600W one, which means the Yeti is more likely to be the unit that refuses to start the exact appliance it's plugged into.
The Yeti 700's continuous output is 600W against the RIVER 2 Pro's 800WThe RIVER 2 Pro's surge ceiling is 1,600W against the Yeti's 1,000W
Why it mattersAnyone planning to run anything with a compressor should weight the RIVER 2 Pro's surge headroom over the Yeti's cycle-life story — a battery that outlasts you doesn't help if the appliance never turns on.
The RIVER 2 Pro's disclosed 62dB figure applies to high-wattage charging and discharging, not overnight CPAP-level draw — the two aren't the same test, and neither manufacturer gives a full night's picture. Treat both as partially unknown rather than assuming the undisclosed Yeti is quieter by default.
The Yeti 700's noise level under load isn't disclosed anywhere in Goal Zero's published specsOne CPAP user reported running the RIVER 2 Pro overnight without issue via a DC-DC cable, in a van, with no complaint about fan noise at that loadA4
Why it mattersCPAP buyers should not assume silence from either brand's marketing; both deserve a return-window test at home before committing to a bedroom setup.
The specific dimensions that decide these two units — everything else is a tie.
PowerScore Breakdown
Selected because: RIVER 2 Pro scores higher (2,183 vs 1,982) despite the Yeti's higher price, which needs explaining.
overall power score
The engine scores the RIVER 2 Pro at 2,183 against the Yeti's 1,982, a gap driven by capacity, continuous output, and price efficiency — the Yeti's higher cycle count isn't enough on its own to overcome starting from less power and a higher sticker price.
Goal Zero's cycle-life and switchover advantages are real, but the composite score reflects what most buyers actually use day to day: how much power is available, and what it costs to get it.
Lifetime Value
Selected because: The Yeti's cycle-life advantage doesn't overcome its higher price in the cost-per-kWh math.
cost / lifetime kWh
The RIVER 2 Pro's $0.22 cost per lifetime kWh beats the Yeti's $0.26 even though the Yeti is rated for 1,000 more cycles — the higher purchase price outweighs the longer cycle life once you divide total lifetime energy by total cost.
Cost per warranty year tells a similar story: $100 for the RIVER 2 Pro against $140 for the Yeti, on identical five-year terms. The Yeti asks for more money every year of that warranty, not just upfront.
What the Specs Don't Tell You
Selected because: Six cards fire — the most of any section here, including a rare cycle-life and noise-disclosure pair worth unpacking.
rated cycles
The cycle-life card is the Yeti's clearest win — 4,000 cycles against 3,000 is a real longevity edge, and for a buyer planning to run this unit daily for a decade-plus, it matters more than any single spec on this page. The UPS card runs the same direction: a 10ms line-interactive switchover against the RIVER 2 Pro's 30ms basic standby is a meaningful gap for anything sensitive to a power gap.
But the noise-disclosure card cuts against the Yeti: Goal Zero simply doesn't publish a noise figure, where EcoFlow's spec sheet — for better or worse — tells you exactly how loud the RIVER 2 Pro gets under loadA2. An undisclosed number isn't evidence of a quiet unit; it's a gap in the information you get to work with before buying.
Brand Trust
Selected because: Cross-brand pair with a real premium-vs-value positioning story.
Goal Zero is the category's original brand, with ruggedized IPX4 designs and an integrated ecosystem of coolers and vehicle kits — but it's also the widely acknowledged most expensive brand per watt-hour, and recent reports describe support wait times stretching for weeks, a real erosion from its premium reputation.
EcoFlow runs the larger, faster-moving ecosystem with the biggest owner community in the category, though support experiences are polarized between smooth replacements and long waits. Between the two, EcoFlow is the better-value brand on this specific pair; Goal Zero is the one you're paying a premium to belong to.

Conclusion
July 15, 2026
Verdict: the RIVER 2 Pro
The RIVER 2 Pro costs $499 for 768Wh and 800W continuous output; the Yeti 700 costs $699.95 for 677Wh and 600W continuous output. That's $200.95 more for 91Wh less capacity and 200W less power — a spec sheet running backward from the price tag. The Yeti answers with a genuine longevity edge, 4,000 cycles against 3,000, and a faster 10ms switchover against 30ms, both real. But the RIVER 2 Pro's $0.22 cost per lifetime kWh against the Yeti's $0.26 shows the cycle-life advantage doesn't close the gap once the higher purchase price is amortized. Buyers who specifically need UPS-grade switchover speed or plan to cycle the unit daily for over a decade should weigh the Yeti's strengths seriously; everyone buying on raw capability per dollar should take the RIVER 2 Pro.

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 2 Pro rates 4.5/5 (72nd percentile of 19 Compact-class units), and Yeti 700 rates 3.6/5 (17th percentile of 19 Compact-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
62dB Is Documented, Not Assumed
EcoFlow discloses the RIVER 2 Pro's high-load noise level on its own spec sheet. That's a data point working against it on paper, though it's specific to high-wattage charging and discharging rather than the quieter, low-draw use a CPAP setup asks of it.
1,600W vs 1,000W of Surge Headroom
The RIVER 2 Pro's surge ceiling gives more room to absorb a compressor's startup spike than the Yeti's, which matters more than either unit's continuous rating for anything with a motor.
10ms Line-Interactive vs 30ms Standby
The Yeti's switchover is genuinely faster and in a different technical class — line-interactive rather than basic standby. For anything sensitive to even a brief power gap, this is the Yeti's clearest structural win.
Same Five Years, Different Annual Cost
$100 per warranty year on the RIVER 2 Pro against $140 on the Yeti — identical terms, different price tags behind them.
4,000 Cycles vs 3,000
The Yeti's extra 1,000 rated cycles is a real longevity edge for anyone planning to run this unit daily for a decade or more. It doesn't overcome the RIVER 2 Pro's lower cost per lifetime kWh, but it's the honest reason to consider paying more.
Goal Zero Doesn't Publish a Noise Figure
There's simply no documented decibel rating for the Yeti 700. That's a gap in the available information, not evidence the unit is quiet — go in expecting an unknown.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 2 Pro
The clearest, most-repeated data point on the RIVER 2 Pro is fan noise: EcoFlow's own spec sheet discloses up to 62dB during high-wattage charging or dischargingA2, and one owner found it loud enough to physically mod the fan, cutting away internal plastic to fit a quieter replacementA1.
Against that, a van-life CPAP user reported the unit running a ResMed AirSense 11 overnight with no issue via a DC-DC cableA4 — a low-draw scenario where the noise complaint doesn't seem to surface. A separate Facebook post asked whether UPS use degrades battery life over timeA3, a question EcoFlow's own materials don't clearly answer. This is thin field data overall; treat it as directional, not conclusive.

The honest catch is that reviewers position it as a lightweight, simple unit rather than a powerful one — good for quick trips and device charging, not the most capable option in its price classB3. Field data here is limited to a handful of review sources rather than deep owner-forum history; there's no long-term complaint thread or idle-drain report to point to either way.

Who Should Buy Which
Buy the RIVER 2 Pro if you…
- →You want more capacity and more continuous output for $200 less — the RIVER 2 Pro wins price, power, and lifetime cost per kWh simultaneously.
- →You're running anything with a compressor, where the RIVER 2 Pro's 1,600W surge ceiling gives real headroom the Yeti's 1,000W doesn't.
Buy the Yeti 700 if you…
- →You're protecting sensitive electronics that can't tolerate even a brief power gap — the Yeti's 10ms switchover is a genuine 20ms faster than the RIVER 2 Pro's.
- →You plan to cycle this daily for a decade-plus and want the extra 1,000-cycle margin, and you're willing to pay $200 more today for it.
If neither fits
If the real job is a weekend camping trip (around 2,100Wh) or an 8-hour multi-appliance blackout (around 1,645Wh), both units come up well short — the Yeti even further short than the RIVER 2 Pro, since it starts from less capacity. Look at a 1,500Wh-plus unit from either brand instead.
The Bottom Line
The Yeti 700 asks for $200.95 more than the RIVER 2 Pro while offering less capacity and less output — the trade is 1,000 extra charge cycles and a faster switchover, both real, neither cheap.
Run the numbers over the unit's full life and the RIVER 2 Pro still costs less per kWh delivered. Take the Yeti only if switchover speed or a decade-plus cycling plan is the specific reason you're buying; otherwise the cheaper, stronger unit is also the better-value one.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
RIVER 2 Pro or Yeti 700 — is the Yeti worth the extra $200?
Only if you specifically need the faster 10ms switchover or plan to cycle the unit daily for a decade or more. On raw capacity, output, and cost per kWh, the cheaper RIVER 2 Pro wins across the board.
Which one lasts longer?
The Yeti 700 on cycle count — 4,000 rated cycles against the RIVER 2 Pro's 3,000. But the RIVER 2 Pro still costs less per lifetime kWh delivered, because its lower purchase price outweighs the Yeti's longer rated life in the engine's math.
Can either one start a fridge or window AC?
The RIVER 2 Pro has more headroom — a 1,600W surge ceiling against the Yeti's 1,000W — which matters because compressor startup can briefly draw 2-3 times the rated wattage. Neither is guaranteed to start every compressor appliance, but the RIVER 2 Pro has more margin.
Is the Yeti 700 quiet?
Goal Zero doesn't publish a noise figure for the Yeti 700 at all, so there's no documented number to compare. Don't assume it's quieter than the RIVER 2 Pro's disclosed 62dB just because Goal Zero doesn't say — it's an unknown, not a point in its favor.
Which one is better for CPAP use?
Both handle the low draw of a CPAP without issue on paper, and one RIVER 2 Pro owner reported exactly that in practice, running a ResMed AirSense 11 overnight via a DC-DC cable. Since the Yeti's noise level isn't disclosed, test either unit during a return window if bedroom noise is the deciding factor.
