Spec deltas
The EcoFlow RIVER 2 Pro (768Wh) and Goal Zero Yeti 300 (297Wh) sit in different weight classes. The real question: do your power needs justify the larger unit, or would you be overpaying for capacity that sits unused? We'd buy the RIVER 2 Pro.
The RIVER 2 Pro holds 471Wh more than the Yeti 300 — about 4 hours on a fridge against 2 — a real but modest edge that shows up mainly on longer outages. For camping, tailgating, or keeping devices charged, both have the headroom, so price, weight, and longevity lead the decision instead.
Pick the RIVER 2 Pro if your primary use is cpap overnight. Go with the Yeti 300 if its specific strengths below line up better with your use. Most buyers stop at the sticker price and miss this: over a full lifespan the RIVER 2 Pro works out to about $0.15/kWh against the Yeti 300's $0.29, a gap that compounds in the RIVER 2 Pro's favor the more you cycle it. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.
Bench Notes
What each unit does well, where it falls short, and the trade-offs that matter.
EcoFlow RIVER 2 Pro
At 800W, this unit is strictly for personal electronics (phones, laptops) and small CPAP machines. Do not expect to run kitchen appliances. At only 17.2 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party. A standout feature is the value proposition: at roughly $0.45 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Costs $0.9 less
- +Larger battery capacity

Neither unit
The Yeti 300 can start the 400W peak but not hold it — 600W of surge gets it going, then the 350W continuous rating takes over, so capacity never gets a say. This is the wrong size of unit for the job rather than a close call.

Phones and a speaker at the park, beach, or campsite — the small-unit job description
Either unit
This row is here for the Yeti 300's class of job: phones and a speaker, 100Wh across an afternoon. Both cover it — the Yeti 300 finishes at 40% used, and the RIVER 2 Pro barely notices it. For this job the RIVER 2 Pro's extra capacity is dead weight, not headroom; take the Yeti 300 at 13.7 lbs and leave the rest at home.

Runtime model
Runtime = (rated capacity × 0.85 inverter efficiency) ÷ device wattage. Solar recharge estimates assume panels deliver 70% of rated output. Cold weather, battery age, and stacked loads reduce real-world results.
Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
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 4.7/5 (84th percentile of 20 Compact-class units), and Yeti 300 rates 3.7/5 (24th percentile of 22 Personal-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
RIVER 2 Pro: 62dB Under Load
62dB is about as loud as a normal conversation. The Yeti 300 publishes no figure to compare it against, which cuts both ways. For most people, fan noise around 45dB and up is where sleep starts to suffer.
UPS Switchover: ≤20ms vs ≤30ms
Both list a UPS mode, at different rated speeds. The Yeti 300 is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. The RIVER 2 Pro is rated ≤30ms — a transfer this long is one many desktops will NOT ride through, so plan on reboots for sensitive gear. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here.
Battery Lifespan in Real Years
The Yeti 300 is rated for 4,000 cycles vs 3,000. In real life: at daily use, that's 11 vs 8.2 years. At weekend use (twice a week), it's 38 vs 29 years. One caution reading years across different sizes: a cycle is 297Wh on the Yeti 300 and 768Wh on the RIVER 2 Pro, so count lifetime energy — roughly 1,188 kWh against 2,304 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.
Yeti 300: Noise Level Not Disclosed
The RIVER 2 Pro publishes its noise level (62dB); the Yeti 300 doesn't publish one. That isn't evidence the Yeti 300 is louder — it means there's no figure to hold it to, and no way to compare the two on this without hearing them. If you're buying for a bedroom, a CPAP, or an apartment, treat the RIVER 2 Pro's 62dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the Yeti 300 before deciding.
Full record above — the Test Desk pick is the RIVER 2 Pro.

Analyst note
The RIVER 2 Pro wins on both sticker price and long-term value. At $0.15/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. One caution on the lifespan row: the Yeti 300 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the RIVER 2 Pro still delivers more over its shorter horizon (2,304 vs 1,188 kWh). Years measure wear, not usefulness.

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
Tested subscription paywalls for advanced app features in early 2025 before community backlash paused the plan. No parts or service offered out of warranty.
Goal Zero
Ecosystem
Focused — a compact current line (6th-gen Yeti and Yeti Pro series), the previous-gen X series still widely sold, 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
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
Typically the priciest brand per watt-hour — though individual pairings vary, and on some pages the Yeti is the cheaper energy. Support quality has declined from its "premium" standard. Perceived as competitively stagnant vs. faster-innovating Chinese competitors. Reliability reports on newer models are concerning.
Analyst note
EcoFlow and Goal Zero are close competitors. Both have established support channels and growing ecosystems. Compare their specific warranty terms and community size for your peace of mind.
Growth path
RIVER 2 Pro
FIXED CAPACITYFixed at 768Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 220W of solar. Limited to a single portable panel.
Adequate ports for most setups, but heavy users may want a power strip.
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 RIVER 2 Pro gives you the larger ceiling); you can't add to either later.
The Bottom Line
The full picture comes down to this. The RIVER 2 Pro edges ahead on our overall analysis, but the margin is narrow enough that your specific use case should drive the decision. Review the scenario verdicts above — if the Yeti 300 wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the RIVER 2 Pro nor the Yeti 300 feels like the right fit, your power needs probably sit outside what these two target. If you're planning whole-home backup or running power-hungry appliances (electric heaters, window AC), you'll want a larger system in the 3,000–5,000Wh range with expansion battery support. Prices on portable power stations fluctuate frequently. Both EcoFlow and Goal Zero discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
"4,000 vs 3,000 cycles" — what does that actually mean for me?
In real years: the Yeti 300 (4,000 cycles) lasts 11.0 years at daily use, 38 years at weekend use (twice a week), or 167 years at twice-monthly camping trips. The RIVER 2 Pro (3,000 cycles): 8.2 years daily, 29 years weekends, or 125 years twice-monthly. What most people miss: hitting the cycle limit doesn't kill your battery. Capacity drops to about 80%. Your 297Wh unit becomes a ~238Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
Is EcoFlow or Goal Zero more reliable for long-term ownership?
Both brands have strengths and trade-offs. EcoFlow: Mixed. 2-5 years depending on model (DELTA Pro Ultra line gets 10 years). Some users report smooth claims; others report runarounds. Register your product to extend coverage. Goal Zero: 5 years on LFP models, 2 years on older NMC models. Battery must be charged within 7 days of purchase and every 6 months to maintain warranty (strict). Product reliability concerns have increased — repeat "Battery Fault" errors reported even on newer Yeti Pro 4000. One piece of advice from the power station community: regardless of brand, buy from Costco or Amazon. Their return policies provide a safety net that manufacturer warranties alone can't match, especially for a product you'll rely on in emergencies. Both brands use LFP (lithium iron phosphate) batteries in their current lineup, the most proven chemistry for longevity and safety.
Bottom line: should I buy the RIVER 2 Pro or the Yeti 300?
We'd buy the RIVER 2 Pro. Cheaper and more capable. That combination is rare. The Yeti 300 doesn't offer a compelling reason to spend more unless you specifically need a feature unique to the Goal Zero ecosystem (expansion batteries, app integrations). Otherwise, clear call.
