Wenny’s take
Portable Power Tester
Same platform, different tier. The RIVER 2 Pro costs 67% more ($140) than the RIVER 2 for more power, more capacity, or both. Does the upgrade earn that premium, or is the base model already enough? The RIVER 2 Pro has a slight edge, but the margin is close enough that your use case should break the tie.
The "pro" upgrade nets you 512Wh more capacity (4h vs 1h on a fridge); 500W more output. That extra headroom starts appliances the base model chokes on; faster solar charging (220W vs 110W input). The gut check: if you're running a CPAP and charging phones, the RIVER 2 has more than enough headroom. If you're powering a fridge during a multi-day blackout or running an RV setup with an AC unit, you'll burn through the RIVER 2's capacity and wish you'd stepped up.
Pick the RIVER 2 Pro if your primary use is cpap overnight. Go with the RIVER 2 if its specific strengths below line up better with your use. 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
At 300W, this unit is strictly for personal electronics (phones, laptops) and small CPAP machines. Do not expect to run kitchen appliances. At only 7.8 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party.
Strengths
- +Lighter by 9.4 lb
Trade-offs
- –No major technical downsides compared to rival.
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
- +Larger battery capacity
- +Higher AC output
- +Faster solar charging
Trade-offs
- –Can receive complaints about fan noise under heavy load.

Two nights off-grid with essential comfort
Neither unit
Neither unit covers this scenario's 2,100Wh: the RIVER 2 comes up 1,882Wh short (about 10% covered), the RIVER 2 Pro 1,447Wh (31%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
RIVER 2 Pro
The RIVER 2 doesn't finish — 218Wh usable against the 320Wh this needs leaves it 102Wh short, about 68% of the scenario covered. The RIVER 2 Pro covers it with 333Wh to spare.

SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Neither unit
The RIVER 2 can start the 400W peak but not hold it — 600W of surge gets it going, then the 300W 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. The RIVER 2 Pro doesn't have the energy either — 653Wh usable against 670Wh, 17Wh short — so neither route works.

Afternoon Off-Grid
Phones and a speaker at the park, beach, or campsite — the small-unit job description
Either unit
This row is here for the RIVER 2's class of job: phones and a speaker, 100Wh across an afternoon. Both cover it — the RIVER 2 finishes at 46% used, and the RIVER 2 Pro barely notices it. For this job the RIVER 2 Pro's extra capacity is dead weight, not headroom; at 7.8 lbs the RIVER 2 is the easier carry, but it is no longer sold, so the RIVER 2 Pro is the one to plan around.

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 rates 3.9/5 (38th percentile of 25 Personal-class units), and RIVER 2 Pro rates 4.7/5 (84th percentile of 20 Compact-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
RIVER 2 Pro: 62dB Published
62dB is about as loud as a normal conversation. It is EcoFlow's own rating rather than a reading on a shared bench — EcoFlow publishes this figure as a maximum under load, where most makers publish a best case, so this one is the pessimistic end rather than the optimistic one, so treat it as a starting point rather than what you would hear at a bedside. For most people, fan noise around 45dB and up is where sleep starts to suffer.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here.
RIVER 2: Noise Level Not Disclosed
The RIVER 2 Pro publishes its noise level (62dB); the RIVER 2 doesn't publish one. That isn't evidence the RIVER 2 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 RIVER 2 before deciding.
Full record above — the Test Desk pick is the RIVER 2 Pro.

│ warranty ends · Reaching the cycle rating means ~80% capacity remains — degraded, not dead.
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 RIVER 2 Pro works out at $0.15/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 RIVER 2 Pro about 2,304 kWh. One thing to know reading the table: both carry the same 3,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.
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.
Accepts up to 110W of solar. Limited to a single portable panel.
Limited ports. You'll likely need a power strip or splitter.
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.
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 RIVER 2 Pro: it is sealed at 768Wh, so buy the size that covers you now. The RIVER 2's fixed 256Wh still matters if you already own one, but it isn't a reason to pick it over the RIVER 2 Pro.

What owners praise
Claims are weighted by how specific they are, whether the commenter owns the unit, and how many readers agreed. Comments that mention a product under a rival's review count for more, because the commenter had no reason to be there. This is what buyers report, not our test results — for measurements we ran ourselves, see the methodology.
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 RIVER 2 wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the RIVER 2 nor the RIVER 2 Pro 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 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.
How does the 512Wh capacity difference actually affect daily use?
The RIVER 2 Pro's 768Wh battery keeps a mini-fridge running for roughly 4 hours vs the RIVER 2's 1 hours. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The RIVER 2 Pro's extra capacity provides a critical cold-weather buffer. For occasional phone and laptop charging, both are overkill. This gap only matters for sustained, multi-appliance use.
Bottom line: should I buy the RIVER 2 or the RIVER 2 Pro?
We'd buy the RIVER 2 Pro. The RIVER 2 is no longer sold, so there is no price to weigh it against; the comparison on this page still helps if you own one.
