Spec deltas
I live out of a Subaru, so the first thing I'd ask of either of these is whether I could sleep next to it. The RIVER 3 PLUS is the light one, with the far lower fan rating. The RIVER 2 Pro is the one with nearly three times the energy.
The Pro holds 768Wh against the PLUS's 286Wh. It costs $90 more, and it's still the cheaper battery per watt-hour.
Output is closer than the batteries suggest. The PLUS runs 600W against the Pro's 800W, and both take the same 220W from panels. If you're worried the PLUS can't power your gear, it mostly can. What it can't match is how long it keeps going.
What the Numbers Reveal
Each conclusion stated first β the numbers behind it on one line, the full analysis below.
cost / lifetime kWh
The extra $90 buys 482Wh, and every one of the Pro's cycles moves nearly three times the energy.
RIVER 2 Pro: 768Wh, $0.15 per lifetime kWh over 3,000 cyclesRIVER 3 PLUS: 286Wh, $0.30 per lifetime kWh over 3,000 cyclesRIVER 2 Pro price: $349; RIVER 3 PLUS price: $259
Why it mattersIf you'll cycle it often, budget by cost per watt-hour. The sticker gap tells you less.
Scale it down to one CPAP night and the Pro finishes with about half its usable battery left. The PLUS runs out before morning.
Weekend Camping needs 2,100Wh: RIVER 2 Pro uses 322% of usable capacity, RIVER 3 Plus uses 864%Van Life Daily needs 4,685Wh: RIVER 2 Pro uses 718%, RIVER 3 Plus uses 1,927%CPAP Overnight needs 320Wh: RIVER 2 Pro uses 49%, RIVER 3 Plus uses 132%
Why it mattersFor one CPAP night, the Pro. For a weekend, a bigger station.
The specific dimensions that decide these two units β everything else is a tie.
Lifetime Value
Selected because: The Pro is cheaper to own, and the gap per watt-hour is roughly two to one.
cost / lifetime kWh
Both batteries are LiFePO4, a long-lived lithium chemistry, rated for 3,000 full charge cycles. At one a day both last a little over eight years on paper. The Pro's bigger battery moves more energy on each cycle, which is why it costs $0.15 per lifetime kWh against the PLUS's $0.30.
The PLUS wins one line. Both carry the same five-year warranty and the PLUS costs less, so each year of cover is cheaper.
Your Life, Your Pick
Selected because: Most jobs here are too big for either unit; the CPAP night is the clear exception.
Seven jobs run on this page, and two get a clear answer. Phones and a speaker for an afternoon is easy for both. An overnight CPAP goes to the Pro, which finishes with plenty left while the PLUS runs out before sunrise.
The rest are too big for either. A weekend, an 8-hour blackout, a remote workday and a day of van life all drain both batteries before the job is done. The Pro misses the tailgate by 17Wh, which is one small appliance switched off a little early.
Growth Path
Selected because: The PLUS's expansion port looks like an edge until you compare it with the Pro's bigger fixed battery.
The Pro's 768Wh is fixed for good. The PLUS can add capacity later, but it starts 482Wh behind, so a first add-on battery mostly closes a gap the Pro never had. The port starts paying only once your real need passes 768Wh.
What the Specs Don't Tell You
Selected because: Fan noise and UPS switchover speed are the two flags that change who should buy which.
EcoFlow lists the Pro's fan at up to 62dB, reached when it charges or discharges at high wattageA2. That's about as loud as a normal conversation. One owner opened the case and modified the fanA1. The PLUS is listed at 30dB. The two figures may describe different operating conditions, and none of our sources measured both side by side, so the gap is only a direction.
The PLUS's UPS is also rated faster: 10ms or less against 30ms or less on the Pro. Switchover is the gap between the wall power dropping and the battery taking over. Many desktops won't ride through 30ms, so plan on reboots with the Pro. A lamp or a fridge won't notice either.
Portability & Form Factor
Selected because: A 6.8 lb gap is a daily difference for a unit you carry.
weight
The PLUS weighs 10.4 lb and the Pro 17.2. You won't notice the difference on the first trip from the car. You'll notice it on the fifth.
If I were hauling one up the Dipsea steps, I'd take the PLUS. None of that changes which one holds more energy.

Conclusion
October 25, 2026
Verdict: the RIVER 2 Pro, on Power Score margin
The RIVER 2 Pro has 482Wh more battery, and it costs less per watt-hour at purchase and over its life: $0.15 per lifetime kWh against $0.30. It's also the only one of the two that gets a CPAP through the night. The PLUS wins back real ground. It's 6.8 lb lighter, its fan rating is far lower, its UPS is rated faster, and it takes an expansion battery. For anyone buying runtime, the Pro is the better buy at current prices.

Each unit's star score is a category ranking, not customer reviews β 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 5β . Here, RIVER 2 Pro rates 4.7/5 (84th percentile of 20 Compact-class units), and RIVER 3 PLUS rates 5.0/5 (99th percentile of 25 Personal-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
RIVER 2 Pro: Loud When It Works Hardest
EcoFlow lists the RIVER 2 Pro's fan at up to 62dB when it charges or discharges at high wattage, about as loud as a normal conversation. The RIVER 3 PLUS is listed at 30dB. The two figures may describe different conditions, so treat the gap as a direction.
Fixed 768Wh vs a Path That Starts Smaller
The RIVER 2 Pro's 768Wh is fixed, so buy the capacity you need up front. The RIVER 3 PLUS can add capacity later, but it pulls ahead only once you need more than 768Wh.
Switchover Rating: β€10ms vs β€30ms
The RIVER 3 PLUS is rated at 10ms or less, the RIVER 2 Pro at up to 30ms. Many desktops won't ride through 30ms, so expect reboots on the Pro. A lamp, a fridge or a phone charger won't notice either. Both are published ratings, and nobody has timed them here.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. Worth saying because the per-dollar framing can suggest otherwise: the RIVER 3 PLUS works out at 19.3 years of cover per $1,000 spent against the RIVER 2 Pro's 14.3, but that spread is the price gap, not the terms.

Analyst note
The RIVER 3 PLUS is cheaper to buy, but the RIVER 2 Pro is cheaper to own.

Analyst note
Don't read the RIVER 3 PLUS's expandability as a straight win here: it starts at 286Wh, below the RIVER 2 Pro's 768Wh, so a first expansion battery largely buys back capacity the RIVER 2 Pro already includes. It only pulls ahead if you'd grow past 768Wh β short of that, the RIVER 2 Pro's larger fixed capacity is the simpler value.
What Owners Report

One owner who wrote up a fan fix for the RIVER 2 later did the same mod on a RIVER 2 Pro, cutting away some internal plastic to make it fitA1.
In a CPAP forum thread about the RIVER 2 Pro, a new user living in a van says a ResMed DC cable runs their AirSense 11 overnight with no problemA4. That cable skips the inverter and runs the machine straight from DC. The excerpt credits their battery bank, and the full post wasn't retrievableA0, so it says little about the RIVER 2 Pro.

Who Should Buy Which
Buy the RIVER 2 Pro if youβ¦
- βYou want the bigger battery for the money. The Pro costs $90 more and still works out cheaper per watt-hour.
- βYou run a CPAP overnight and don't want to think about the battery. The Pro finishes the night with about half its usable charge left.
- βYou'd rather buy the right size once than add an expansion pack later.
Buy the RIVER 3 PLUS if youβ¦
- βYou carry it daily, into a room, a trunk or a tent. 10.4 lb against 17.2 is a real difference by the end of a week.
- βIt lives near where someone sleeps, and the Pro's 62dB fan rating worries youA2.
- βYou're protecting a desktop or network gear and want the faster switchover rating: 10ms or less, against up to 30ms on the Pro.
- βYour need fits well under 286Wh today and might grow later.
If neither fits
If you're planning a weekend away, a blackout longer than a few hours, or full-time van life, skip this pair. Both batteries run out well before those jobs are done.
The Bottom Line
The RIVER 3 PLUS runs 600W against the Pro's 800W and matches its solar input. It still holds 286Wh against 768Wh, and a first expansion battery mostly catches it up. The Pro is the only one of the two that gets a CPAP through the night.
Buy the RIVER 2 Pro for the bigger battery at the lower cost per watt-hour. Buy the RIVER 3 PLUS if the weight, the Pro's fan ratingA2 or the slower UPS rating would bother you every day.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow RIVER 3 PLUS basically a smaller RIVER 2 Pro?
No, it's a different generation with its own upgrades. The PLUS adds expansion-battery support and a bigger inverter and solar input than the base RIVER 3, plus a much lower fan rating and a faster UPS switchover rating than the RIVER 2 Pro. What it doesn't have is the Pro's bigger battery: 286Wh against 768Wh, 482Wh less to start.
Which one is cheaper to own over its whole life?
The RIVER 2 Pro, despite its higher $349 price against the PLUS's $259. It works out to $0.15 per lifetime kWh against $0.30, and it costs less per watt-hour at purchase too.
Can the RIVER 3 PLUS's expansion battery make up for its smaller base capacity?
Only if you need more than 768Wh. The PLUS starts at 286Wh, well under the Pro's fixed 768Wh, so a first expansion battery mostly closes that 482Wh gap rather than growing past it. Below a 768Wh need, the Pro's larger fixed battery gets you there without the extra purchase.
Is the RIVER 2 Pro too loud to sleep near, like for CPAP use?
Its fan can reach 62dB, but EcoFlow says that happens when charging or discharging at high wattage. One owner modified their unit's fan to quiet it. A CPAP draws far less than that, and the Pro covers a CPAP night using about half of its usable capacity. The RIVER 3 PLUS has the lower fan rating at sub-30dB, but it needs an expansion battery to finish the same night.
Will either of these get me through a multi-day power outage?
No. An 8-hour blackout alone needs about 1,645Wh. The RIVER 2 Pro covers about 40% of that and the RIVER 3 PLUS about 15%. Multi-day coverage needs a larger power station than either.
