Head-to-head test
EcoFlow RIVER 3 vs DJI Power 1000
None of the six real-world loads we test are within the RIVER 3's reach, while the Power 1000 clears two outright and comes within reach of a third — that capability gap, not the $500 between their price tags, is what you're actually buying.

Spec deltas
Take the Power 1000 if you need an actual power station: at $699 it clears two of our six real-world load tests outright, CPAP Overnight and Tailgate Party, while the $199 RIVER 3 clears none of the six. The capacity gap explains why. 1,024Wh against 245Wh is better than four times as much, for three and a half times the price ($699 versus $199).
None of that is about brand. It's about what $199 actually buys. The RIVER 3 runs $0.81 per watt-hour of capacity; the Power 1000 runs $0.68. Play it out over the warranty and the gap holds: $0.27 per lifetime kWh for the RIVER 3 against $0.17 for the Power 1000. The cheaper unit is still the worse deal per watt-hour, both up front and over its life. You're not buying a discount, you're buying less.
So why does the RIVER 3 exist at all? Because 7.8 lbs goes in a daypack and 28.7 lbs is something you carry with both hands and set down deliberately. If your real need is topping off a phone and a laptop on a day trip, the Power 1000's extra capacity is weight and money you'll never use. If your real need is any of the six scenarios on this page, the RIVER 3 was never going to clear them, whatever it costs.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
solar input
DJI scaled the solar port harder than the battery. 800W is 7.3 times the RIVER 3's 110W, versus 4.2 times the capacity. Real sun is never a constant 800W or 110W for that long, so treat both numbers as best case, but the direction holds: the bigger, pricier unit is also the one that claws back a charge faster, not just the one that holds more to begin with.
RIVER 3: 110W max solar input, 245Wh capacityPower 1000: 800W max solar input, 1,024Wh capacityWeekend Camping needs 2,100Wh — more than either unit holds on its own
Why it mattersAnyone leaning on solar to bridge Weekend Camping's 2,100Wh gap should weight that decision on refill speed, not just capacity. The RIVER 3 is slower to refill and has less to refill in the first place.
The Power 1000 uses a little over a third of what it's got powering a CPAP overnight, with real headroom left, and at 23dB against the RIVER 3's 30dB it's the quieter machine too. For the one scenario on this page built around sleeping next to the unit, it wins on the spec that matters and the one that's a bonus.
CPAP Overnight needs 320WhRIVER 3 needs 154% of its usable capacity to run it (over capacity)Power 1000 needs 37% of its usable capacity for the same loadPower 1000 rated 23dB noise vs. RIVER 3's 30dB
Why it mattersIf you're buying to run a CPAP through the night, the RIVER 3 isn't a smaller, cheaper version of an adequate answer. It's short of the job by more than half; get the Power 1000.
600W of surge capacity isn't enough to switch on whatever the tailgate scenario throws at it, while the Power 1000's 4,400W surge, more than seven times the RIVER 3's, clears it without strain, on top of holding enough capacity to run the whole party (77% of usable capacity used, per the model).
RIVER 3 surge rating: 600WTailgate Party is the only scenario where the RIVER 3 can't power the peak load at allPower 1000 surge rating: 4,400W
Why it mattersFor tailgate-style loads with a real inrush spike, coolers, blenders, a portable induction burner, the RIVER 3 isn't a smaller option, it's a non-starter. This is a Power 1000 job or nothing.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Whether either unit can actually carry a real camping trip, blackout, or CPAP night is the only question that matters here, and the RIVER 3 doesn't clear a single one of the six loads we test.
Six scenarios, and the RIVER 3 finishes zero of them. At the extreme (Van Life Daily) it needs 2,250% of its usable capacity, more than twenty times over, and even at its best showing it isn't in range. It's sized for a different job entirely: keeping a phone, tablet, and laptop alive for a day away from an outlet, not carrying a campsite or a blackout.
The Power 1000 does better, but 'better' still has a ceiling. It clears CPAP Overnight and Tailgate Party without strain, needs just 105% of usable capacity for Remote Workday (its closest miss), and then falls well short of the multi-day and whole-load scenarios: 241% for Weekend Camping, 189% for an 8-Hour Blackout, 538% for Van Life Daily. Buying it doesn't mean you've bought whole-cabin backup. It means you've bought the one of these two that can actually run a single appliance through the night, which is the question most people shopping this price range are actually asking.
Lifetime Value
Selected because: A $699 price tag looks steep next to $199 until you divide each by what it actually delivers, and the more expensive unit turns out to be the cheaper one per watt-hour.
cost / lifetime kWh
The RIVER 3's whole pitch is the $199 sticker, but sticker price and cost per watt-hour aren't the same question. The RIVER 3 runs $0.81 per watt-hour of capacity against the Power 1000's $0.68: the 'budget' unit is the more expensive one to buy energy from. Spread each unit's full lifetime output across its price and the gap holds: $0.27 per lifetime kWh for the RIVER 3, $0.17 for the Power 1000. The Power 1000 costs more, full stop, but it isn't the premium option in the sense that actually matters. Dollar for dollar, it's the cheaper energy.
Portability & Form Factor
Selected because: 7.8 lbs versus 28.7 lbs is the one spec that actually argues for the cheaper unit, and it's the real reason to consider the RIVER 3 at all.
weight
7.8 lbs goes in a daypack next to a water bottle and you forget it's there. 28.7 lbs, nearly four times heavier, is a two-hand lift you set down deliberately, not something clipped to a hip belt.
The Power 1000's own portability catch isn't the box, it's the accessory bag: it has no built-in solar charge controller, so pulling power from a panel means packing DJI's proprietary adapter too. The RIVER 3 has no such asterisk. It's smaller, but everything it does, it does on its own.
Brand Trust
Selected because: EcoFlow's recall history and DJI's thin power-station track record are both real considerations for a five-year purchase, pulling in opposite directions.
EcoFlow is the establishment here: 12 to 15 models deep, the largest community in the category, and the fastest-charging tech in the business (their X-Stream system). That scale comes with scale's problems. EcoFlow recalled the DELTA Max 2000 in October 2025 over an overheating and fire risk (six incidents), and tested a subscription paywall on app features in early 2025 before backing off under community pressure. Neither event touches the RIVER 3 specifically, but they're the track record of the company standing behind it.
DJI is the opposite bet: four power station models total, on the market since 2024, with no dedicated power-station community yet. Discussion of the Power 1000 lives inside r/dji, a drone-focused subreddit of roughly 250,000 members. What DJI brings instead is a repair and support network built over a decade of drone hardware, plus a caveat of its own: no built-in solar charge controller, and battery expansion exists on the newer Power 2000 and Power 1000 V2 but not on this base model. Newer company, thinner power-station track record, backed by a hardware maker that already knows how to run a repair network.
What the Specs Don't Tell You
Selected because: Both flagged gotchas are about how these numbers age: one turns out to be a red herring, the other is the most useful year-by-year comparison on the page.
rated cycles
Cost per warranty year looks like it favors the RIVER 3, $40 a year against the Power 1000's $140, but both units carry the same 5-year warranty, so that gap is just the $199-versus-$699 price difference wearing a different unit. It isn't telling you anything the price tag didn't already say.
Cycle life is the more useful number of the two. The Power 1000 is rated for 4,000 cycles against the RIVER 3's 3,000; run either one daily and that's 11 years for the Power 1000 versus 8.2 for the RIVER 3, a real gap if you're actually cycling one every day. Weekend-only use pushes both past the point it matters, 28.8 and 38.5 years, which is the honest caveat on this whole section: most buyers will retire either unit for a better one long before the battery itself quits.
Strengths & trade-offs
EcoFlow RIVER 3
Strengths
- +Costs $500 less
- +Lighter by 20.9 lb
Trade-offs
- –Weaker inverter (-1,900W) limits appliance compatibility.
- –Shorter-lived battery — rated for 3,000 charge cycles vs the Power 1000's 4,000, so it wears out sooner.
DJI Power 1000
Strengths
- +Larger battery capacity
- +Higher AC output
- +Faster solar charging
- +Rated for 4,000 charge cycles — much longer battery lifespan
Trade-offs
- –Substantially more expensive (+$500) than the RIVER 3.
- –Significantly heavier (+20.9 lbs), making it harder to move.

Scenario verdicts
We ran the math on six real-world scenarios. Here's which unit survives your actual life.
SCN-01 · 2 nights · needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Neither of these is sized for a full weekend off-grid. The RIVER 3 needs more than ten times its usable capacity, the Power 1000 close to two and a half times its own. The Power 1000 gets meaningfully closer, but 'closer' still means packing a way to recharge mid-trip either way.

LOAD Phone Charger 15W×6h · LED Lights 40W×8h · Box Fan 75W×14h · CPAP Machine 40W×16h
SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
An 8-hour blackout outdraws both of these badly. The RIVER 3 needs nearly eight times its usable capacity, the Power 1000 almost twice its own. If a whole-home blackout is the actual scenario you're buying for, neither box is it; you want something sized for the job, not scaled up from a travel charger.
Battery budget usedlower = more headroom
LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Power 1000
This is the Power 1000's cleanest win on the page: it uses a little over a third of its usable capacity for the night and does it quietly. The RIVER 3 doesn't have the capacity to finish the night at all. This scenario isn't close.
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
Neither unit
The Power 1000 comes right up to the line here, 105% of usable capacity, its closest miss on the page, while the RIVER 3 needs more than four times its own. Call the Power 1000 'almost' rather than 'yes': a slightly lighter workday and it clears this one too.
Battery budget usedlower = more headroom
LOAD Laptop 60W×8h · External Monitor 30W×8h · Router + Modem 20W×8h · Phone Charger 15W×2h
SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Power 1000
The RIVER 3 doesn't just run short here, it can't even start the peak load; its 600W surge rating isn't enough to switch things on. The Power 1000 handles both the peak and the sustained draw without issue. Not a photo finish.

SCN-06 · 24 hours · needs 4,685Wh
Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Van life's daily draw is the biggest number on this page, and both units miss it by a mile. The RIVER 3 needs over twenty-two times its usable capacity, the Power 1000 more than five times its own. This scenario is a different shopping category entirely: a vehicle-integrated system with real solar, not either of these.

Conclusion
August 1, 2026
Verdict: the Power 1000, on Power Score margin
Buy the Power 1000. It's the only one of these two that clears real-world loads on this page: CPAP Overnight and Tailgate Party outright, Remote Workday within 105% of usable capacity. The RIVER 3 clears none of the six. It also costs less per watt-hour ($0.68 vs. $0.81) and less per lifetime kWh ($0.17 vs. $0.27) despite costing $500 more upfront, so the higher price buys a genuinely better-value unit, not just a bigger one. Pick the RIVER 3 only if your real need is under 245Wh and 7.8 lbs is the deciding spec; otherwise the extra weight and price buy a machine that can actually finish the job.

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 3 rates 4.4/5 (62nd percentile of 22 Personal-class units), and Power 1000 rates 3.9/5 (35th percentile of 24 Everyday-class units).

The Warranty-Year Math Is a Red Herring
Cost per warranty year looks like it favors the RIVER 3, $40 a year against the Power 1000's $140, but both units carry the same 5-year warranty, so that gap is just the $199-versus-$699 price difference wearing a different unit. It's not a separate signal; it's the price tag, restated.
Cycle Life, Converted to Actual Years
3,000 cycles for the RIVER 3 and 4,000 for the Power 1000 sound like abstractions until you convert them: daily use gets you about 8.2 years out of the RIVER 3 and 11 out of the Power 1000. Weekend-only use stretches both past the point it matters, 28.8 years and 38.5 years, which is the honest caveat here: most buyers will retire either unit for a better one long before the battery itself gives out.

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. Supports up to 180kWh modular expansion with DELTA Pro Ultra X.
Worth knowing
The recall and the paywall test aren't about the RIVER 3 itself, but they're EcoFlow's most recent public missteps, and worth knowing before you commit to their ecosystem for the next five years.
DJI
Ecosystem
New entrant (2024) — 4 power station models: Power 500, Power 1000 V2, Power 1000 Mini, Power 2000
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, at the quiet end of the category. Fastest wall-charging speeds (~56 min for V2). 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
DJI is making its first power-station warranty claims on a decade of drone-repair infrastructure, not power-station-specific experience. A reasonable bet, but still a bet, on a base Power 1000 that, unlike DJI's newer models, has no expansion path if you outgrow it.
Analyst note
EcoFlow is the safer ecosystem bet by sheer size: more models, more community, more history to judge them by, warts included. DJI is the newer, quieter, less-tested one. Neither caveat should decide this specific purchase on its own; both belong in the file, not the verdict.
Growth path
RIVER 3
FIXED CAPACITYFixed at 245Wh, 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 3
What field commentary exists for the RIVER 3 is comparative rather than owner-reported: reviewers measuring it against its predecessor rather than long-term owners logging months of useA1A3. The consistent theme is that it improves on the RIVER 2 across the board, quieter, more rugged, and more capableA1A2A4, and it's recommended as the better buy for most 2026 use cases including camping and van lifeA3. That's a real signal, but it's a signal about the RIVER 3 relative to EcoFlow's older model, not about how it performs against a fundamentally larger unit like the Power 1000.
“The RIVER 3 operates under 30 dB — EcoFlow calls it 'whisper quiet,' quieter than a library — one of the most significant upgrades over the louder RIVER 2.”

DJI Power 1000
Owners and reviewers are consistent on one point: this is a quiet machine, only becoming audible past roughly 1,500W and even then as a soft whoosh rather than a whineB1. It also runs past its own spec sheet without complaint: one test ran it at 2,400W, above its 2,200W rating, for 20 minutes with no shutdown and no unusual noiseB2, and AC charging from empty takes about 70 minutes with a fan that's barely audible even at full charging speedB3. Real-world use skews toward exactly the load profile this page's numbers predict: a week-long camping trip running a 45W fridge, phones, laptops, and lights, plus a following among drone pilots charging batteries alongside other devicesB4.
“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.”

Who Should Buy Which
Buy the RIVER 3 if you…
- →Backpackers and dayhikers who need to keep a phone, tablet, and laptop alive and are counting ounces: 7.8 lbs disappears into a daypack.
- →Anyone whose real use case isn't on this page's scenario list at all, like a desk-to-desk backup, a car-charger replacement, or keeping a router and a webcam alive during a short outage.
- →Buyers who've priced out the Power 1000's 1,024Wh and know they'll never draw anywhere near it. Paying for headroom you won't use is its own kind of waste.
Buy the Power 1000 if you…
- →Anyone running a CPAP overnight: the only unit of the two that comfortably clears the load, and the quieter one doing it (23dB vs. the RIVER 3's 30dB).
- →Tailgate and car-camping setups with a real inrush spike, coolers, blenders, induction burners: its 4,400W surge rating is the only one of the two that starts those loads at all.
- →DJI drone owners who already have SDC-compatible batteries and gear, and get a genuine ecosystem benefit the rest of this comparison doesn't capture.
If neither fits
Anyone planning actual multi-day off-grid power, a full blackout backstop, or van-life daily use should skip both. Neither clears Weekend Camping, an 8-Hour Blackout, or Van Life Daily; even the Power 1000 needs up to 538% of its usable capacity on the worst of those (Van Life Daily), and neither unit expands to close the gap. That buyer needs a larger-capacity platform or one built to add battery modules, not the cheaper or the pricier of these two.
The Bottom Line
The Power 1000 wins because it's the only one of these two that shows up to the jobs a power station actually gets bought for. It clears CPAP Overnight and Tailgate Party outright, comes within reach of a third, and does it more quietly and for less money per watt-hour than the 'budget' RIVER 3. The RIVER 3 isn't a bad product. It's just not entered in this particular fight; judged against these six loads, it's a $199 phone charger, not a power station.
Buy the RIVER 3 only if you already know your real load fits in 245Wh and 7.8 lbs is the spec you actually care about. Everyone else weighing a camping trip, a blackout, or a CPAP night should spend the extra money and get the unit that's actually built to survive being asked.

Not on its own. A CPAP Overnight load in our model needs 320Wh, and the RIVER 3's 245Wh capacity means it needs 154% of what it can usably deliver, coming up short before morning. The DJI Power 1000 covers the same load using just 37% of its usable capacity, with room to spare.
Is the DJI Power 1000 worth $500 more than the EcoFlow RIVER 3?
If you need any of the six real-world loads we test, camping, a blackout, CPAP, a workday, a tailgate, or van life, yes: the RIVER 3 doesn't clear a single one, and the Power 1000 clears two outright. If your actual use case is charging phones and a laptop while traveling light, no. You'd be paying for 1,024Wh of capacity you'll never draw down, on a unit nearly four times heavier.
How much solar input do these need to recharge?
The RIVER 3 tops out at 110W of solar input for 245Wh of capacity; the Power 1000 accepts up to 800W for 1,024Wh. In full sun that pencils out to roughly 2.2 hours for a complete RIVER 3 charge against about 1.3 hours for the Power 1000, despite the Power 1000 holding four times as much power. Real-world sun is never that constant, but the Power 1000's solar ceiling is the one actually built to keep up with daily off-grid use.
Does either of these expand with add-on batteries?
No. Both are fixed-capacity units with no expansion path. The RIVER 3 is locked at 245Wh and the Power 1000 at 1,024Wh, so whatever you buy is whatever you'll have. Size the purchase for your actual needs now rather than planning to grow into it later.
Which one is quieter?
The Power 1000, rated at 23dB against the RIVER 3's 30dB, and owner reports back that up: reviewers describe it as inaudible under normal loads and only noticeable as a soft whoosh past roughly 1,500W. The RIVER 3 is also marketed as sub-30dB 'whisper quiet', but with only 245Wh of capacity, it won't be running long enough at CPAP-relevant loads to make the comparison a fair fight.
