Head-to-head test
EcoFlow RIVER 2 vs DJI Power 1000
The Power 1000 carries 4 times the battery for 3.7 times the money, and it's still the cheaper station per kWh over its life. The RIVER 2's whole case is a $189 sticker and a 7.8-pound frame that fits in a backpack.

Superseded — buy the V2
DJI has superseded the Power 1000 with the Power 1000 V2 — same $699, with 2,600W output against 2,200W. The original may still be purchasable while stock lasts, but unless it is meaningfully discounted, buy the V2.
Power 1000 V2 · $699.00Spec deltas
Two very different jobs are hiding inside one search query. The RIVER 2 is a $189, 7.8-pound backup for phones and small electronics; the Power 1000 is a $699, 1,024Wh station built to run real loads quietly. Once you price out the electricity each one delivers over its life, the bigger unit turns out to be the cheaper one to run per kWh, not just the pricier one to buy.
Neither station is actually built for a full weekend of off-grid camping or a multi-day blackout. Both fall well short of those loads, and neither has a way to expand later, so buy the ceiling you need today, not the one you hope to grow into. Where the Power 1000 pulls ahead is the medium-draw jobs: an overnight CPAP, or a tailgate's worth of speakers and a mini-fridge, both of which the RIVER 2 can't finish and the Power 1000 handles with room to spare.
That combination — more capacity, quieter running on paper, and a lower lifetime cost per kWh — makes the Power 1000 the better all-around station, and the pick here. The catch is real: it costs $510 more up front and weighs 28.7 pounds against the RIVER 2's 7.8, so if your budget stops at $189 or you need something that vanishes into a daypack, the RIVER 2 is still a perfectly reasonable unit for that narrower job.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
Add in the Power 1000's 4,000-cycle rating against the RIVER 2's 3,000, and the gap widens: seventeen cents per kWh across its lifetime versus twenty-five cents for the RIVER 2.
RIVER 2: $189 for 256Wh, 3,000 cyclesPower 1000: $699 for 1,024Wh, 4,000 cycles
Why it mattersAnyone planning to actually cycle the battery for years, not just keep it in a closet as a backup, comes out ahead buying the bigger unit even though it costs more today.
Neither model has an expansion path either, so there's no bolt-on fix later: if your real use case is a weekend off-grid or a van you live in, both of these are simply the wrong size class.
Weekend Camping needs 2,100Wh; the Power 1000 still falls short at 241% of its capacityVan Life Daily needs 4,685Wh, which is 538% of the Power 1000's capacityNeither unit has an expansion path — both are fixed-capacity
Why it mattersBuyers whose actual load is a multi-day camping trip, a full work-from-van day, or a long blackout should skip this matchup entirely and look at a station with several times the capacity of either one.
For a station you might run for hours beside a tent, a desk, or a bed, that stops being a spec-sheet number and becomes the difference between forgetting it's on and listening to it all nightA1B1.
RIVER 2 rated at 50dB, Power 1000 at 23dBEcoFlow's own comparison materials note the RIVER 2 runs louder under load than the RIVER 3 that replaced itA1Reviewers repeatedly single out the Power 1000 as one of the quietest stations in its classB1B2
Why it mattersBuyers sensitive to fan noise, CPAP users, light sleepers, anyone working near the unit, should weight this above the price gap.
solar input
That matters most exactly when the grid is down, and the 8-Hour Blackout scenario already shows both units short of its 1,645Wh draw. A bigger solar array is the only way to claw back capacity mid-outage, and only the Power 1000 brings one worth mentioning.
RIVER 2 accepts up to 110W of solar inputPower 1000 accepts up to 800W of solar input8-Hour Blackout needs 1,645Wh, more than either unit can fully deliver
Why it mattersAnyone leaning on solar to ride out a multi-day outage gets a more serious tool in the Power 1000, even though neither unit alone covers a full 8-hour blackout outright.
The specific dimensions that decide these two units — everything else is a tie.
PowerScore Breakdown
Selected because: 1,585 vs 3,099 is the cleanest single summary of the whole matchup and frames everything else.
overall power score
A power score of 3,099 against 1,585 is not a photo finish. That gap traces straight back to output and capacity — 2,200W and 1,024Wh against 300W and 256Wh — not some soft weighting the algorithm invented. The RIVER 2 was never built to compete in the Power 1000's segment. It's a hatchback parked next to a pickup, and the score is just reporting that honestly.
Lifetime Value
Selected because: Cost-per-lifetime-kWh flips the price story: the pricier unit is the cheaper one to run, which is the crux of the verdict.
cost / lifetime kWh
Sticker price points to the RIVER 2. Total cost of ownership points the other way. Run each unit through its full cycle life and the RIVER 2 lands at twenty-five cents per kWh delivered, the Power 1000 at seventeen. The extra $510 at checkout buys a battery that's also cheaper to run once you're past the first year.
On a weekend-only cycle, that gap shrinks to about two cents a day for the RIVER 2 and five cents a day for the Power 1000, both trivial, which is the point: at light, occasional use, price is really the only variable that matters. The gap becomes real money only if you're cycling the battery hard for years, which is exactly when the Power 1000's extra 1,000 rated cycles start paying for themselves.
Portability & Form Factor
Selected because: 28.7 vs 7.8 lbs is a real physical tradeoff buyers feel every time they move the unit.
weight
7.8 pounds is one-hand, off-the-shelf portable. The RIVER 2 disappears into a backpack next to a water bottle without you noticing the extra weight. The Power 1000 is a different physical object at 28.7 pounds: still a one-person lift, but you're using your legs, not your wrist, and setting it down with intent rather than tossing it on the passenger seat. That's not a flaw. It's the tradeoff for carrying 4 times the energy in roughly the same basic shape, and you're not paying that weight penalty for nothing.
Your Life, Your Pick
Selected because: Four of six scenarios return neither; buyers need that honesty before comparing anything else.
Four of the six scenarios here come back neither: Weekend Camping, the 8-Hour Blackout, Remote Workday, and Van Life Daily all demand more than either unit can deliver, some by a wide margin. Van Life Daily's 4,685Wh need is more than 4 times even the Power 1000's 1,024Wh capacity — this pair isn't shopping in that weight class. Anyone carrying that kind of load should look at a larger station category entirely, not choose between these two.
The two scenarios that do split are the lighter, single-purpose ones. CPAP Overnight needs 320Wh; the RIVER 2 runs dry partway through the night while the Power 1000 covers it using just 37% of its capacity. Tailgate Party's 670Wh ask is the same story: the RIVER 2 runs out, and the Power 1000 finishes having used just 77% of its capacity.
What the Specs Don't Tell You
Selected because: Noise, UPS speed, warranty parity, and cycle life all cut toward the Power 1000 and explain the fine print.
rated cycles
Two fine-print numbers favor the Power 1000 beyond the headline specs. Its 20-millisecond switchover beats the RIVER 2's 30 for backup duty — both fast enough that most electronics won't notice, but one is meaningfully quicker than the other. Its battery is also rated for 4,000 charge cycles against the RIVER 2's 3,000, which is where the lifetime cost-per-kWh gap from the section above actually comes from.
Warranty term is the one spec that doesn't split either direction: five years on both. The dollar-per-warranty-year gap ($38 for the RIVER 2 against $140 for the Power 1000) is really just the price difference wearing a different unit. It says nothing about which company trusts its own battery more, since both are backing the identical five-year term.

Conclusion
July 28, 2026
Verdict: the Power 1000, on Power Score margin
Buy the Power 1000 if you can spend $699: it wins on cost per lifetime kWh, covers the CPAP Overnight and Tailgate Party scenarios the RIVER 2 can't finish, and carries roughly 2x the RIVER 2's power score. The RIVER 2 remains the right call only if your budget caps at $189 or you need something that disappears into a daypack at 7.8 pounds. For that narrower job, it's still a perfectly capable little unit.

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 4.1/5 (48th percentile of 22 Personal-class units), and Power 1000 rates 3.8/5 (28th percentile of 26 Everyday-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.
UPS Switchover: ≤20ms vs ≤30ms
Both list a UPS mode, at different rated speeds. The Power 1000 is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. The RIVER 2 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. Worth saying because the per-dollar framing can suggest otherwise: the RIVER 2 works out at 26.5 years of cover per $1,000 spent against the Power 1000's 7.2, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The Power 1000 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 1,024Wh on the Power 1000 and 256Wh on the RIVER 2, so count lifetime energy — roughly 4,096 kWh against 768 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.
RIVER 2: Noise Level Not Disclosed
The Power 1000 publishes its noise level (23dB); 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 Power 1000's 23dB 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.

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.

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.
DJI
Ecosystem
New entrant (2024) — five power station models to date: Power 500, Power 1000 (since superseded by the V2 but still sold), Power 1000 V2, Power 1000 Mini, Power 2000. Buying a "Power 1000" listing? Check which revision it actually ships.
Support
Leveraging DJI's established global support and repair center network from the drone business. Generally positive reputation inherited from drone operations, but limited power-station-specific track record.
Community
No dedicated power station community yet. Discussions happen within r/dji (~250K members, mostly drone users). Very small power-specific presence on Facebook and forums.
App experience
Rated 3.5/5 iOS and Android (DJI Home app ratings reflect entire DJI ecosystem including drones/cameras, not power-station-specific). Users report the on-device screen is more reliable than the app.
Unique strength
Runs quiet — 23-30dB published across the line (manufacturer best-case figures), at the quiet end of the category. Fast wall charging, quickest on the Power 1000 V2 at ~56 min — that figure is the V2's, not the whole line's. 700+ battery patents from drone R&D. SDC ports for ultra-fast DJI drone charging. Premium industrial design and build quality. LFP batteries rated for 4,000+ cycles.
Worth knowing
Still a new entrant to power stations, with about two years of track record in the category so far. There's no built-in solar charge controller, so solar charging needs a separate proprietary adapter, and the SDC fast-charge ports are proprietary to DJI's own ecosystem, so a chunk of the platform's extra value depends on already owning DJI gear.
Analyst note
EcoFlow has the deeper bench here: more models, a much larger owner community, and years more track record in portable power specifically. DJI brings drone-grade engineering and a notably well-built, quiet unit to a category it only entered recently. Neither brand edge decides this matchup by itself — the RIVER 2 and Power 1000 are different enough in size and price that the units do most of the deciding.
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.
Power 1000
FIXED CAPACITYFixed at 1,024Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 800W of solar. Suitable for a 1-2 panel setup.
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 Power 1000 gives you the larger ceiling); you can't add to either later.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 2
Most of what's written about the RIVER 2 compares it to its newer RIVER 3 sibling rather than standing alone, but the pattern holds across sources: it shares the same core platform, including 300W output and LiFePO4 chemistry, and remains a genuinely popular small budget unitA2. For strictly indoor, every-dollar-counts use, reviewers still call it a reasonable buyA3.
The recurring knock is fan noise. EcoFlow's own comparison materials and review coverage note it runs noticeably louder under load than the RIVER 3 that replaced it, without publishing a specific under-load dB figure of its ownA1. It also lacks the RIVER 3's waterproofing and faster UPS switchoverA3, refinements EcoFlow added later rather than flaws unique to this unit.
“Shares the same core platform as the RIVER 3 — 300W output, LiFePO4 chemistry, and roughly 60-minute fast charging — and remains a popular, proven budget small-format unit.”

DJI Power 1000
Coverage skews toward first-impression reviews rather than years of ownership. DJI is a newer entrant to power stations, and a newer V2 version of this unit already exists, so most of what's written is short-trip testing, not long-term reliability data. Even so, the theme is consistent: testers call it one of the quietest stations in its class, with sound only becoming noticeable at high load and even then described as a soft whoosh rather than a whineB1. One outlet pushed it past its rated output for an extended stretch without triggering a shutdown or loud fan noiseB2.
Real-world use skews toward exactly the buyers you'd expect. Reviewers ran it through a multi-day camping trip powering a compressor fridge, phones, and laptops without issue, and drone pilots have adopted it as a favorite for topping off flight batteries while still running other gearB4. Charging back up is also reported as fast, with the fan staying unobtrusive even at full charging speedB3.
“Whisper-quiet operation — one of the quietest power stations in its class, nearly silent under normal loads; sound only becomes noticeable past 1,500W, and even then it's a soft whoosh rather than the high-pitched whirring you'd get from BLUETTI or EcoFlow.”

What owners complain about
Bought and tested it: 140W is out of the USB-C port's league.
Chargingmeasuredowner9 agreedsource →
The 400W MPPT modules run hot and throttle solar watts until he added copper heatsinks.
Build qualitymeasuredowner5 agreedsource →
Says the inverter draws about 50W, which DJI never mentions but which decides real autonomy.

What owners praise
Ordered one on Amazon for under $400 in a November deal.

Confirms DJI's quietness claim while charging is not exaggerated.

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.
Who Should Buy Which
Buy the RIVER 2 if you…
- →Buy the RIVER 2 if your backup job is small: phones, a laptop, a router, maybe a fan, the kind of load that fits inside 256Wh and where $189 is the whole budget conversation.
- →It's also the right call if portability is non-negotiable. At 7.8 pounds it rides in a backpack or a car door pocket, and you'd rather carry less and recharge more often than haul a heavier station you rarely use at full capacity.
Buy the Power 1000 if you…
- →Buy the Power 1000 if you need to actually run something for hours: a CPAP overnight, a fridge and lights at a tailgate, a laptop-heavy remote workday. Those are jobs the RIVER 2 measurably can't finish and this one covers with capacity to spare.
- →It's also the pick if you're budgeting for years of use rather than one trip. It costs less per kWh over its life than the RIVER 2, and with 1,000 more rated cycles, the higher price amortizes into the cheaper habit over time.

If neither fits
Skip both if your real load is a full weekend of off-grid camping, a multi-day blackout, or a van you live and work out of full time. Weekend Camping, the 8-Hour Blackout, Remote Workday, and Van Life Daily all demand more than even the Power 1000's 1,024Wh can deliver, some by several times over. That buyer needs a station built for 2,100Wh-and-up jobs with real expansion room, not a choice between these two.
The Bottom Line
The math keeps landing the same way: 4 times the capacity, a quieter rating on paper, and a lower cost per kWh over its life make the Power 1000 the better station, if you can absorb the $510 higher price and the extra weight on your back. That's a real cost, not a rounding error, so it's worth being honest about who it's for.
Buy the RIVER 2 for exactly what it is: a capable $189, 7.8-pound backup for small stuff, and don't apologize for not needing more. Buy the Power 1000 when the job is bigger than a phone charge: CPAP, tailgate, years of real cycling. Either way, buy for the load in front of you, not the one you imagine someday having.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the EcoFlow RIVER 2 run a CPAP machine all night?
Not reliably on its own. CPAP Overnight is a 320Wh job in this comparison's model, and the RIVER 2's 256Wh capacity comes up short — it would need 147% of what it holds to make it through the night. The Power 1000 covers the same night using just 37% of its capacity, with plenty of margin left.
Is the DJI Power 1000 worth the extra money over the EcoFlow RIVER 2?
If you'll actually use the extra capacity, yes. The Power 1000 holds 4 times the RIVER 2's 256Wh, wins the two scenarios in this comparison where a real appliance runs for hours (CPAP Overnight and Tailgate Party), and costs less per kWh over its life: seventeen cents against twenty-five. If your loads are small enough that the RIVER 2 already covers them, the extra $510 buys capacity you'll never touch.
Which is quieter, the EcoFlow RIVER 2 or the DJI Power 1000?
The Power 1000, by a wide margin on the spec sheet — it's rated at 23dB against the RIVER 2's 50dB. Reviewer accounts back the spec sheet up here too: the Power 1000 is consistently singled out as one of the quietest stations in its class, while the RIVER 2's fan is the most common complaint against it, particularly under load.
Can either of these run a fridge through a full camping weekend?
No. Weekend Camping is modeled here as a 2,100Wh job, and the RIVER 2 covers only a fraction of it while the Power 1000 falls short too, needing 241% of its own capacity to try. Both would need to be paired with solar or swapped for a larger station — this isn't a job either one finishes alone.
Can you add extra batteries to the RIVER 2 or the Power 1000 later?
No. Both are sealed, fixed-capacity units with no expansion path: 256Wh is the ceiling for the RIVER 2, 1,024Wh is the ceiling for the Power 1000. Size your purchase for the job you actually have, because neither one grows into a bigger job later.
