Head-to-head test
EcoFlow RIVER 2 Pro vs Jackery Explorer 1000 Plus
You're not paying $350 extra for 496 more watt-hours: you're paying it for a 2,000W inverter, more than three times the solar input, and a ceiling you can raise later, and if your whole load list fits inside 653 usable watt-hours none of that is yours to use.

Spec deltas
$699 against $349 for 496 more watt-hours is a bad trade, if watt-hours are what you're shopping for. They aren't, quite. The Explorer 1000 Plus holds 1,264Wh to the RIVER 2 Pro's 768Wh, but it also runs 2,000W against 800W and takes 800W of solar against 220W, and those two specs settle more of this matchup than the battery does.
Start with what both boxes do. A 320Wh CPAP night is 49% of the RIVER 2 Pro's usable energy and 30% of the Jackery's, so if that's the whole job the cheap one is the right one. Push up to a 910Wh workday and the RIVER 2 Pro stops 257Wh early, at about 72% of the day. Push to a 1,645Wh blackout and neither box finishes.
That's the shape of it. The RIVER 2 Pro lives at the edge of the loads people actually plan for, and the Jackery lives a comfortable margin above them without ever being outage-proof on its own. One of the two can be grown past that ceiling. The other is sealed at 768Wh for as long as you own it.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
So the premium isn't energy at all. Set the batteries aside and look at what else changes: output goes from 800W to 2,000W and solar input from 220W to 800W. You are buying an inverter and a charger, and the extra 496Wh comes along for the ride.
RIVER 2 Pro: $349 for 768Wh, about 45 cents per watt-hourExplorer 1000 Plus: $699 for 1,264Wh, about 79 cents per watt-hourLifetime cost: $0.15 per kWh across 2,304 kWh vs $0.20 across 5,056 kWh
Why it mattersIf nothing you own draws more than 800W and you're never waiting on a recharge, you'd be paying $350 for headroom you'll never touch. Buy the RIVER 2 Pro.
Seventeen watt-hours is a rounding error you can unplug your way out of. Two hundred and fifty-seven is a different thing, because the 800W ceiling means you can't shorten a workday by charging faster in a gap. The Explorer 1000 Plus turns both rows from arithmetic into a non-question, finishing with 164Wh and 404Wh spare.
RIVER 2 Pro: 653 usable Wh after the flat 15% derateTailgate Party needs 670Wh, a 17Wh shortfall; Remote Workday needs 910Wh, a 257Wh shortfallCPAP Overnight needs 320Wh and leaves the RIVER 2 Pro 333Wh spare
Why it mattersIf you can see yourself counting watt-hours on a Saturday, you've already outgrown the RIVER 2 Pro. Skip the stage.
solar input
Those hours are also the loud ones. High-wattage charging is precisely the regime EcoFlow's 62dB figure describesA2, so the RIVER 2 Pro spends the better part of an afternoon there, every day of an outage, to put back less. The Jackery is done before lunch.
Solar input: 220W on the RIVER 2 Pro vs 800W on the Explorer 1000 Plus8-Hour Blackout needs 1,645Wh; neither unit covers it (40% and 65%)EcoFlow publishes 62dB for the RIVER 2 Max and Pro at high-wattage charging and dischargingA2, and one owner fitted quieter fans, cutting away internal plastic to make them fitA1
Why it mattersAnyone buying for multi-day outages should treat recharge speed as the capacity spec. It's the one that repeats.
The expansion bay is the only route either unit has to the rows both currently fail. It has a hard limit though: batteries add watt-hours, not watts. The inverter stays 2,000W however many you bolt on, and field testing puts the appliance list at whatever fits inside that ratingB3. More hours, same house.

Why it mattersIf outage coverage is the actual goal, buy the Jackery expecting to add a battery, or skip both and price a larger platform now.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Five of the six loads we model sit above 653 usable watt-hours, which is where this $350 decision actually gets made.
Look at where the RIVER 2 Pro's numbers land and a pattern shows up: huge margin on the small job, tiny deficit on the medium one. It finishes a CPAP night with 333Wh untouched, then comes up 17Wh short of a tailgate. Its nameplate 768Wh clears that 670Wh day on paper. The flat 15% conversion allowance we apply to every unit is what takes it to 653 usable and tips it under.
The Jackery's version of the same table is boring, which is the point. A 320Wh night goes three times into its 1,074 usable watt-hours and twice into the RIVER 2 Pro's 653, and the workday and the tailgate finish with 164Wh and 404Wh in the tank. Three rows still read neither, and those are rows where both boxes are the wrong size rather than rows one of them lost.
Lifetime Value
Selected because: The cheaper box is also the cheaper one per unit of energy over its rated life, fifteen cents a kilowatt-hour against twenty, and that's the strongest argument against our own pick.
cost / lifetime kWh
The best argument against our own pick lives here. Across its rated life the RIVER 2 Pro delivers 2,304 kWh for $349, about fifteen cents a kilowatt-hour; the Jackery delivers 5,056 kWh for $699, about twenty. Bigger batteries normally win this metric on volume alone. This one doesn't, and its 4,000 cycles against 3,000 don't close the gap.
So don't let anyone tell you the Explorer 1000 Plus pays for itself, because on energy it never does. Read the number for what it is: a ceiling on how good a deal the premium can be, not permission to ignore the 800W inverter you'd be living with instead. Cheap watt-hours you can't pull fast enough are a discount on the wrong thing.
Growth Path
Selected because: One of these can add batteries later and one is sealed at 768Wh, and three of our six scenarios are out of reach for both of them today.
solar input
Sealed at 768Wh means the number on the box is the number in five years, so the RIVER 2 Pro has to be sized for the job you have rather than the one you suspect is coming. The Jackery takes expansion batteries, and reviewers put the full stack at about 5,000WhB2. Derated the same way as everything else on this page, that's roughly 4,250Wh usable, past both scenarios where the base units fall short by four figures.
Two honest caveats before you price the bay as capacity. Expansion adds watt-hours and not watts, so the appliance list stops at 2,000W no matter how tall the stack gets. And an expansion battery is a second purchase you haven't made yet. Buy the Jackery for what it does at 1,264Wh, and treat the growth path as an option you're glad to have rather than energy you already own.
What the Specs Don't Tell You
Selected because: Two published numbers here are not what they look like: a 62dB rating that describes high-wattage charging, and two UPS transfer times that are ceilings rather than results.
rated cycles
The 62dB on the RIVER 2 Pro isn't a quiet-mode floor. EcoFlow's own documentation gives it as what the RIVER 2 Max and Pro may reach when charging or discharging at high wattageA2, which is a worst case, while the Jackery's 30dB is the usual best-case rating. Those two figures came off opposite ends of two different tests, so subtracting one from the other measures nothing. What the specs do support: the loud regime on the RIVER 2 Pro is fast charging, and at 220W of solar input it sits in that regime about three and a half hours to refill from empty against the Jackery's hour and a half.
The UPS line is the spec you can't work around. A load can be trimmed to fit 653 usable watt-hours; a transfer time can't be trimmed at all. Both makers publish ceilings rather than stopwatch results, no worse than 20ms for the Explorer 1000 Plus and no worse than 30ms for the RIVER 2 Pro, and a gap as long as 30ms is one plenty of desktops will not ride through. If what you're protecting is a computer with unsaved work, that's the number to weigh. Warranty isn't: both cover five years, Jackery's conditional on registering the unit.
Portability & Form Factor
Selected because: 17.2 lbs against 32 lbs is the one axis the RIVER 2 Pro wins outright.
weight
17.2 lbs is a one-hand carry out of a trunk. 32 lbs is two hands, bent knees, and you put it down where you intend to leave it. That's 14.8 lbs of difference on an object whose entire premise is that it moves.
This is the RIVER 2 Pro's clean win and it isn't a small one for the right buyer. If the box lives in a closet and comes out twice a year, weight is a footnote. If it goes in and out of a car every weekend, the lighter one is worth giving something up for. Just be clear about what: the workday, the tailgate, and any route past 768Wh.
Strengths & trade-offs

Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Neither unit covers this scenario's 2,100Wh: the RIVER 2 Pro comes up 1,447Wh short (about 31% covered), the Explorer 1000 Plus 1,026Wh (51%). Treat this as partial cover — enough for the essentials in it, not the whole list.

8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
Neither box finishes this one, so the useful comparison is how far short each falls: 992Wh for the RIVER 2 Pro and 571Wh for the Explorer 1000 Plus against a 1,645Wh evening, or 40% and 65% covered. Both are essentials boxes here rather than outage boxes. What separates them is what happens next, because one takes expansion batteries and the other is finished at 768Wh for good.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Explorer 1000 Plus
A 40W machine for eight hours is 320Wh, and both of these cover that several times over, so the percentages are a formality. Count nights instead. That 320Wh night goes three times into the Explorer 1000 Plus's 1,074 usable watt-hours and twice into the RIVER 2 Pro's 653, which finishes the second morning with 13Wh left. If a recharge is guaranteed every day, either box does this job. If the power is out and the sun isn't cooperating, the third night belongs to the Jackery alone.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
Explorer 1000 Plus
The RIVER 2 Pro gets you about 72% of the way through a 910Wh day, which in practice means it quits in the afternoon rather than at quitting time. 653 usable watt-hours against 910 is a 257Wh gap, and that isn't a gap you close by dimming a screen. The Explorer 1000 Plus finishes with 164Wh in hand. That's margin, not comfort, so if your days run long, plan on a panel or an outlet either way.

Tailgate Party
Game day power for the crew
Explorer 1000 Plus
The RIVER 2 Pro loses this one by 17Wh, the most frustrating number on the page. Its nameplate 768Wh clears the 670Wh the day needs; the flat 15% conversion allowance takes it to 653 usable and tips it under. Trim one small appliance's worth across the day and it finishes. The Explorer 1000 Plus doesn't ask you to do arithmetic at all, covering the same day with 404Wh spare and 2,000W of inverter for whatever gets plugged in at halftime.

4,685Wh isn't a comparison, it's a different product category. These two cover 14% and 23% of it, a few hours of the day. If this is your real daily draw, stop pricing boxes this size and start pricing a larger platform, or a properly wired system with its own battery bank.

Conclusion
September 13, 2026
Verdict: the Explorer 1000 Plus, on Power Score margin
Take the Explorer 1000 Plus. It wins three of the six scenarios we model and the RIVER 2 Pro wins none, and the two rows that separate them are the ordinary ones: a 910Wh remote workday the Jackery finishes with 164Wh in hand, and a 670Wh tailgate the RIVER 2 Pro misses by 17Wh. Be clear that the $350 premium never comes back in energy. Over its rated life the Jackery costs about twenty cents a kilowatt-hour against the RIVER 2 Pro's fifteen, so on stored energy alone the expensive box stays the expensive box. What the money buys is 2,000W of output instead of 800W, about an hour and a half of strong sun to refill instead of three and a half, and a battery bay that isn't sealed. If your list is a CPAP, a laptop and a couple of phones and you're confident it stays that way, the RIVER 2 Pro does that job for a third of the price and 14.8 fewer pounds. Everyone else ends up at the Jackery eventually, and it's cheaper to arrive once.

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 Explorer 1000 Plus rates 4.6/5 (77th percentile of 27 Everyday-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
RIVER 2 Pro: 62dB at High-Wattage Charging
The RIVER 2 Pro's 62dB is a published maximum for charging and discharging at high wattage, not a quiet-mode floor. The Explorer 1000 Plus's 30dB is the usual best-case figure. Those two numbers come off opposite ends of two different tests, so subtracting them tells you nothing about what you'd hear with both boxes on a table. Here's what the specs do support: the loud regime on the RIVER 2 Pro is fast charging, and at 220W of solar input it needs about three and a half hours of strong sun to refill 768Wh, against roughly an hour and a half for the Jackery's 1,264Wh at 800W. More than twice as long in the noisy state, and that state is the one where the unit is least useful to you.
Sealed at 768Wh, and What Expansion Actually Buys
768Wh is the RIVER 2 Pro's ceiling today and in five years, so size it for the job in front of you rather than the one you suspect is coming. The honest catch on the other side of the comparison: the Explorer 1000 Plus's expansion adds watt-hours, not watts. The inverter stays 2,000W however many batteries you hang off it, so the stack buys longer runtimes on the same appliance list, never a bigger one. Each battery is also a separate purchase, which means the sane way to buy the Jackery is for what it does at 1,264Wh, with the bay as an option you're glad you have.
UPS Switchover: ≤20ms vs ≤30ms
Both list a UPS mode, at different rated speeds. The Explorer 1000 Plus 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. The Explorer 1000 Plus's figure is a maximum rather than a guarantee — it depends on registering the unit with Jackery, which is what extends the base term to the full period. Worth saying because the per-dollar framing can suggest otherwise: the RIVER 2 Pro works out at 14.3 years of cover per $1,000 spent against the Explorer 1000 Plus's 7.2, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The Explorer 1000 Plus 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 1,264Wh on the Explorer 1000 Plus and 768Wh on the RIVER 2 Pro, so count lifetime energy — roughly 5,056 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.

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
EcoFlow has the deepest lineup in the category and the most active community in it, which in practice means someone has already solved your problem in a forum thread. Two things to file away: the company tested subscription paywalls for advanced app features in early 2025 and backed off after the response, and it offers no parts or service once the warranty is up.

US-based support but widely criticized. Reddit reports describe slow/dismissive responses, scripted AI agents, strict receipt requirements for warranty claims, and refurbished replacements for clearly defective units. Strongly recommended: buy from Costco or Amazon for return protection.
Community
Smallest community of the major brands — Reddit r/Jackery has ~2,000 members. YouTube presence is solid due to brand recognition.
App experience
Rated 2.3-3.3/5 iOS and Android — the weakest app experience of the major brands. Multiple confusing apps (Jackery app vs Jackery Home) and mandatory login even offline.
Unique strength
Highest brand recognition and widest retail distribution (Costco, Home Depot, Best Buy, Amazon). The "Toyota" of power stations — dependable, proven, wide availability. Innovative form factors like the Solar Gazebo and Solar Mars Bot.
Worth knowing
Jackery's real advantage is that you can put your hands on one. It's stocked at Costco, Home Depot, Best Buy and Amazon, which matters more than it sounds, because a retailer's return window is a better warranty than a support queue. The trade-offs are the weakest app of the major brands and the smallest community, at roughly 2,000 members on Reddit.
Analyst note
Support is the weak column for both of these brands, and it's the one thing they genuinely have in common. Long waits, strict receipt requirements and refurbished replacements for units that failed new all show up in the record on both sides, which makes the practical advice identical either way: buy from a retailer with a real return policy rather than direct. Everywhere else they split. EcoFlow brings the bigger ecosystem and the far better app, Jackery brings a box you can carry back into a store.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 2 Pro
Field evidence on this exact box is thin, and that's a finding rather than an excuse. Our research pass could confirm only four RIVER 2 Pro-specific entries, because most of what's online discusses the RIVER 2 line without saying which of the units is actually in the roomA0.
What survives the filter is mostly about the fan. EcoFlow's own documentation says the RIVER 2 Max and Pro may reach 62dB when charging or discharging at high wattageA2, and one owner went as far as fitting quieter fans, which meant cutting away some internal plastic to make them fitA1. The CPAP thread that names this unit is really about running an AirSense 11 from a DC-DC cable rather than through the inverter, and it doesn't tie that result to a RIVER 2 ProA4. The UPS material we could verify is a question someone asked, not a reportA3.

The Jackery is the one with a track record. A six-month test across dozens of camping trips, two extended outages and daily home-office use reported it running every appliance inside its 2,000W rating, and in a simulated outage it held a refrigerator, lights, a laptop and a router at the same timeB3. Reviewers also report full wall recharges in under two hours and an LFP pack that reaches its 4,000-cycle ratingB1.
Reviewers consistently land on the same two reasons to buy it, expandability and outputB2B4. One caution from our own coverage note, aimed squarely at our pick: the design carries no dust or water ingress ratingB0. It's a tent-and-tailgate box, not a jobsite one.
“The LiFePO4 battery genuinely hits 4,000 cycles, AC recharge consistently shows ~1.7-hour full charges, and the 2,000W pure sine wave inverter handles surge loads.”

Who Should Buy Which
Buy the RIVER 2 Pro if you…
- →Your list is a CPAP, a couple of phones and a laptop, and you'd like two nights of it for $349. A 320Wh night goes twice into 653 usable watt-hours, with 13Wh left on the second morning.
- →The unit gets carried. 17.2 lbs goes in one hand, over a tailgate, down basement stairs, into the back of a car without a second thought.
- →You already own something bigger and want a light second box for the tent while the big one stays home with the fridge.
Buy the Explorer 1000 Plus if you…
- →You work a full day away from an outlet. A 910Wh day finishes with 164Wh in hand, where the RIVER 2 Pro stops about 72% of the way through it.
- →Something you own draws more than 800W. That isn't slow on the RIVER 2 Pro, it's off, and the Jackery's 2,000W has 4,000W of surge behind it for whatever kicks on.
- →You're prepping for outages and you accept that getting there takes an expansion battery. It's the only one of these two with a route past its own nameplate.
If neither fits
If your day looks like the van-life row, 4,685Wh of which these two cover 14% and 23%, neither of these is the answer and no amount of price comparison makes one. The same goes for real blackout coverage without sun: that row needs 1,645Wh and the bigger of these two still comes up 571Wh short. Close the tab and price a larger platform built for multi-day loads, or a properly wired system with its own battery bank, and think of a box this size as the one you add later for the tent.
The Bottom Line
Buy the Explorer 1000 Plus. It wins three of the six scenarios we model and the RIVER 2 Pro wins none, and the rows that separate them are the unremarkable ones: a workday the Jackery finishes with 164Wh to spare, and a tailgate the cheaper box misses by 17Wh. The premium never comes back in energy, and we'd rather say that than pretend a $699 box is a bargain at a price per kilowatt-hour it doesn't hit.
The RIVER 2 Pro is still right for a narrow, honest job: a CPAP and a phone, twice over, at 17.2 lbs and a third of the price. If that's genuinely your list and it isn't growing, take the cheap one and put the $350 somewhere else. If you hesitated reading that sentence, you already know which one to buy.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery Explorer 1000 Plus worth nearly three times the price of the EcoFlow RIVER 2 Pro?
If your loads run past 653 usable watt-hours or past 800W, yes. The extra $350 buys 496Wh, which is about $1.31 for each added watt-hour against the 45 cents a watt-hour the RIVER 2 Pro charges, so you are plainly not buying the energy. You're buying a 2,000W inverter, 800W of solar input and the option to add batteries later.
Can the EcoFlow RIVER 2 Pro run a CPAP all night?
Yes, with room left over. A 40W machine for eight hours is 320Wh against 653 usable watt-hours, so it ends the night with 333Wh spare and can manage a second night before it needs a recharge. The open question isn't capacity, it's the fan. EcoFlow's published 62dB describes high-wattage charging and discharging rather than a 40W draw at your bedside, and no measured figure at that load exists in our evidence.
Will either of these get me through an 8-hour blackout?
Not from the battery alone. That load is 1,645Wh, and the RIVER 2 Pro covers about 40% of it while the Explorer 1000 Plus covers about 65%, leaving them 992Wh and 571Wh short. Either one runs the essentials on that list for an evening. Covering the whole thing takes expansion batteries or a bigger platform.
Which one is quieter to sleep next to?
Probably the Jackery, but the published numbers don't prove it. Its 30dB is a best-case rating, while the RIVER 2 Pro's 62dB is EcoFlow's own worst case at high-wattage charging and discharging, so the two figures sit at opposite ends of different tests. The supporting detail worth knowing is that one owner fitted quieter fans to a RIVER 2 Pro, cutting away internal plastic to do it, which is not something people do to a unit that's already silent.
Can I add more capacity to the RIVER 2 Pro later?
No. It's sealed at 768Wh, so it has to be sized for the job you have now. The Explorer 1000 Plus takes expansion batteries, with reviewers putting a full stack at about 5,000Wh. If you think your needs will climb, that's the side of this comparison with somewhere to go.
