Spec deltas
The RIVER 2 Max is EcoFlow's cheap, light answer to 'I just need backup power.' The Power 1000 is DJI's answer to the same question for buyers who need more of everything and are willing to pay for it: $699 (last listed price) against $289 (last listed price), 1,024Wh against 512Wh, 2,200W against 500W. This isn't a photo finish.
Thirteen pounds is a one-hand carry up a flight of stairs. Twenty-nine pounds is a two-hand, watch-your-back lift, and that gap tracks the capability gap. The RIVER 2 Max is sized for phones, laptops, and a CPAP. The Power 1000 is sized to run something that actually pulls power, like a compressor fridge or a space heater, without flinching.
That's the trade. EcoFlow built the RIVER 2 Max for the buyer who wants the lightest, cheapest box that still does the job. DJI built the Power 1000 for the buyer who wants the job done bigger and quieterB1, and is fine paying $410 more (on last listed prices) for it. For most people cross-shopping these two, the Power 1000 is the one to buy, but only if that extra weight and price are actually in budget.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
The Power 1000's 4,400W ceiling clears the same startup spike with room left over, which is the real reason the output gap matters more than the capacity gap. A bigger battery that can't start the appliance is just a heavier paperweight.
RIVER 2 Max: 500W continuous output, 1,000W surgePower 1000: 2,200W continuous output, 4,400W surge
Why it mattersBefore picking the cheaper unit for anything with a compressor, check that appliance's startup draw against 1,000W. On paper the RIVER 2 Max looks like it's in the running; in practice it may never turn the thing on.
solar input
That's the gap between a battery you refill over a full sunny day and one you can refill in a few hours with panels stacked, except the Power 1000 needs a separate proprietary adapter to accept solar at all, since it doesn't ship with a built-in charge controller the way the RIVER 2 Max's XT60 input does.
RIVER 2 Max solar input tops out at 220WPower 1000 solar input tops out at 800W
Why it mattersSolar-dependent buyers should price in that adapter before assuming the bigger input number is free.
rated cycles
A third more rated cycles on a battery that costs 2.4 times as much still edges ahead on lifetime cost, because the price gap doesn't scale as fast as the cycle-life gap does.
RIVER 2 Max: $289 (last listed price), rated for 3,000 cyclesPower 1000: $699 (last listed price), rated for 4,000 cycles
Why it mattersTreat the sticker price as a budget question, not a value question. On lifetime cost per kWh these two are close enough to call a wash, so let the capacity and output gap decide instead.
It's also why the engine calls CPAP Overnight for the Power 1000 even though the RIVER 2 Max has more than enough capacity for the load. Capacity was never the constraint on this one. The fan was.
RIVER 2 Max's own spec sheet flags it as the louder of the two under loadPower 1000 owners consistently report it staying quiet even pushed above its rated outputB1B2B3
Why it mattersIf a CPAP, a nightstand, or a desk you sit at all day is the actual use case, weight the noise gap heavier than the spec sheet does. It's the difference that wakes you up.
The specific dimensions that decide these two units — everything else is a tie.
What the Specs Don't Tell You
Selected because: The only spec-invisible flag with real decision weight is noise; the other three (UPS speed, warranty economics, cycle life) are real but minor.
rated cycles
Four flags fire on this pair, and only one is rated a warning: the RIVER 2 Max's fan noise under load. The other three, switchover speed, warranty economics, and cycle life, are real but minor. None of them would flip a buying decision on its own.
Noise is the one that can. Both units pass through power fast enough to protect sensitive electronics during an outage, both carry the same five-year warranty, and the Power 1000's extra rated cycles are a nice-to-have rather than a deciding factor for anyone who isn't cycling one daily. Fan noise is different. It's the one flag here that changes where you'd physically put the unit, and owners back it up consistently for the Power 1000B1B2B3.
Your Life, Your Pick
Selected because: Six real loads show the neither-is-big-enough pattern and explain why the two scenarios either unit CAN cover both land on the Power 1000.
Run all six real-world loads and a pattern falls out: whenever one of these two units is actually big enough to finish the job alone, it's the Power 1000. Camping for a weekend, riding out a blackout, working untethered from the grid, living in a van full time: none of those are a fair fight for either battery. They're jobs for something considerably bigger.
The two scenarios sized right for this pair, an overnight CPAP and a tailgate spread, both go to the Power 1000, for different reasons. CPAP overnight is a noise call, not a capacity call: the RIVER 2 Max has capacity to spare, it's just the louder of the two doing it. Tailgate Party is a straight capacity call the RIVER 2 Max can't cover from a single charge. If your use case looks like one of these two, that's the answer. If it looks like the other four, neither of these is actually the right product.
Portability & Form Factor
Selected because: 13.4 lbs vs 28.7 lbs is the most physically felt difference between these two and drives a chunk of who-buys-which.
weight
The Power 1000 weighs more than double what the RIVER 2 Max does, and that's not incidental. It's the direct cost of the bigger inverter and battery pack that make the output and capacity gap possible. You feel that difference the moment you're the one carrying it to the tailgate or up from the basement.
It partly earns the extra weight back in solar flexibility: its input ceiling is more than three times the RIVER 2 Max's, so on a sunny day it can take more panels at once. That's a real edge if you already own panels. For anyone who just wants the lightest box that'll keep a phone and a laptop alive, the weight gap is the whole story, and it's not close.
Lifetime Value
Selected because: cheaperToOwn favors the Power 1000 narrowly; has to be stated honestly even though it isn't the deciding factor.
Sticker price makes the RIVER 2 Max look like the value pick, and for anyone who won't run either unit especially hard, it is. You'll retire the box for other reasons long before you burn through 3,000 cycles. Run the math across each unit's full rated cycle life instead and the order technically flips: the Power 1000 lands a couple cents lower per lifetime kilowatt-hour.
That's a real number, not a rounding error, but it's also not the point. Nobody should buy a $699 (last listed price) battery to save two cents a kilowatt-hour. The decision is about whether you need the extra capacity and output, and the lifetime-cost math just confirms that paying more here isn't also paying a premium for nothing.
Growth Path
Selected because: Both are sealed and fixed-capacity, which closes off the 'can I add to it later' question buyers of either will ask.
solar input
Neither of these expands, and that's not a strike against either one. Both are sealed, complete units at their stated capacity, not a starter tier of something bigger. What you buy on day one is what you own for good.
The only real decision is up front. The Power 1000 gives you double the ceiling to grow into if your needs are still settling, while the RIVER 2 Max asks you to be confident that 512Wh is enough today, because there's no add-on tank, no second battery, no path to more once it ships.

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
A weekend of camping draws around 2,100Wh, more than four and a half usable charges from the RIVER 2 Max and better than two full charges from the Power 1000. Neither is sized for this trip solo; plan on a solar refill partway through, or step up to a larger station.

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 needs roughly 1,645Wh. The Power 1000 gets closer, about two usable charges, while the RIVER 2 Max would need almost four. Both fall short as a single-charge solution; this is where a generator or a bigger battery earns its keep.
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
Either unit
A CPAP overnight pulls about 320Wh. That's roughly three-quarters of a RIVER 2 Max charge and a little over a third of a Power 1000 charge. Both machines can finish the night on capacity alone, but the Power 1000 does it with well over half its charge still in reserve.
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
A full remote workday off-grid runs about 910Wh. The RIVER 2 Max needs roughly two charges to cover it, and even the bigger Power 1000 comes up just short of one, at 105 percent of a usable charge. Neither clears this solo; pair one with a solar panel or plan to top up midday.
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
A tailgate spread draws about 670Wh. The RIVER 2 Max would need more than one and a half charges to cover it solo; it's not close. The Power 1000 handles it in one, with about a quarter of its usable charge left over.
Battery budget usedlower = more headroom

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Van life runs about 4,685Wh a day, more than ten RIVER 2 Max charges or more than five Power 1000 charges. This isn't a fair fight for either box; van-life buyers should be shopping in a considerably bigger capacity class, ideally with dedicated solar input to match.

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 Max rates 3.7/5 (26th percentile of 20 Compact-class units), and Power 1000 rates 4.3/5 (58th percentile of 27 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.
RIVER 2 Max: 62dB Published
Push the RIVER 2 Max toward its rated output and the fan is the loudest thing in the room. The Power 1000 stays close to silent doing the same job. For a desk, a bedroom, or a CPAP a few feet away, that gap is the whole ballgame. Everywhere else, it's background noise.
RIVER 2 Max: Fixed Capacity
The RIVER 2 Max is sealed at 512Wh, and that is the ceiling. Normally the counterpoint would be that the Power 1000 can add expansion batteries, but that isn't a live option here: the Power 1000 is no longer sold, and DJI points owners to the Power 1000 V2. For a new purchase the expansion question doesn't arise between these two, so the RIVER 2 Max's fixed 512Wh is simply what you get.
UPS Switchover: ≤20ms vs ≤30ms
Both units switch to battery well under a second when the wall power cuts, 30ms for the RIVER 2 Max and 20ms for the Power 1000. Either is fast enough to save a router or a phone charger. The gap only starts to matter for gear that's genuinely picky about interruption-free power, like some CPAP machines or a desktop mid-save.
Warranty: No Difference
Both units carry an identical 5-year warranty, so length isn't the differentiator. What differs is what you're fronting for that coverage: the Power 1000 costs more than double the RIVER 2 Max up front, so its cost per warranty-year runs proportionally higher too. That's arithmetic on the price tag, not a statement about which battery is built to last longer.
Battery Lifespan in Real Years
The Power 1000 is rated for 1,000 more charge cycles than the RIVER 2 Max, 4,000 against 3,000, both on LFP chemistry built to shrug off daily use. Short of cycling one of these daily, both units are more likely to be replaced by a newer model than worn out by cycle count.

Analyst note
Neither is sold new any more, so there is no price left to work a cost per kWh from, and what either costs you now depends on the used market. The hardware comparison still holds: over its rated life the RIVER 2 Max delivers about 1,536 kWh and the Power 1000 about 4,096 kWh.
Brand trust
EcoFlow
Ecosystem
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.
Community
Largest community in the space — Reddit r/Ecoflow_community (~31K members), multiple Facebook groups, and an official community forum
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
EcoFlow's real edge is X-Stream fast charging and sheer product breadth, more than a dozen models spanning RIVER through DELTA Pro, plus solar panels and smart-home panels, all under one app.
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
DJI's pitch is tightly engineered, quiet hardware backed by drone-grade battery R&D. The operation is the quietest in the category, and the build quality reads like it.
Worth knowing
DJI has been in the power station business for about two years, against EcoFlow's much longer run, a shorter track record to judge long-term reliability against, even though the drone-era support network behind it is well established.
Analyst note
EcoFlow is the safer ecosystem bet: a bigger lineup, a bigger community, and more history to judge it by. DJI is the newer, more focused player, betting that quieter hardware and drone-grade engineering are worth walking in without that history. Neither brand risk is severe enough to override what the two units actually do.
Growth path
RIVER 2 Max
FIXED CAPACITYFixed at 512Wh, 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.
Power 1000
EXPANDABLESupports DJI expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 1,024Wh.
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.
Expansion batteries are DJI-specific. You're investing in the DJI ecosystem.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Neither of these is sold new any more, so there is no growth path to buy into on either side. If you already own one: the RIVER 2 Max is fixed at 512Wh and the Power 1000 takes expansion batteries. As a purchase decision, expandability isn't the question here.

DJI Power 1000
The consistent theme across reviews is quiet, even when pushed. Testers ran it above its rated output for a stretch with no loud noise and no shutoff, and one review flagged it as quieter than comparable EcoFlow and BLUETTI units doing the same jobB1B2. Charging is unobtrusive too: reviewers clock a full AC charge in well under ninety minutes with the fan barely audible the whole timeB3. Over a week of actual camping it ran a compressor fridge, phones, laptops, and lights without drama, and it's become a favorite among drone pilots for fast-charging batteries on the sideB4.
“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 2 Max if you…
- →Your loads are phones, laptops, a router, maybe a CPAP. Nothing with a compressor, nothing running eight hours straight. The RIVER 2 Max covers all of that for meaningfully less money and about half the weight of the Power 1000.
- →You want the lightest thing you can grab on the way out the door, into a car, a backpack, up from a basement, without needing a second person to help carry it.
- →You mostly use it outdoors, in a garage, or in the car, not at a bedside or a desk, so the RIVER 2 Max's fan noise under load never actually becomes a problem you notice.
Buy the Power 1000 if you…
- →You're running something with a compressor, a fridge, a window AC, or anything else that needs sustained real watts, not just a device that sips power. The RIVER 2 Max's output ceiling won't touch that; the Power 1000's more than quadruples it.

If neither fits
If you're planning a full weekend of camping, bridging a multi-hour blackout, working untethered for a full day, or living out of a van full time, skip both. Neither is sized for that job solo, and you'll be better served by a station sized for 2,100Wh or more instead.
The Bottom Line
The Power 1000 is the more capable machine here: double the capacity, more than four times the output, and a fan that stays out of the way while it does itB1B2B3. That capability costs $410 more (on last listed prices) and roughly double the weight, which is a real cost, not a footnote, and it's exactly why the RIVER 2 Max remains the right call for anyone whose actual loads are light.
But if you're cross-shopping these two at all, you probably need more than a phone charger, and on lifetime cost per kilowatt-hour the pricier unit isn't even asking you to pay a premium for the privilege. Buy the RIVER 2 Max for what it is: light and cheap. Buy the Power 1000 for what it does: more, and quieter.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DJI Power 1000 worth paying more for over the EcoFlow RIVER 2 Max?
If you need the extra capacity, output, or quiet, yes. The Power 1000 has double the usable capacity, more than four times the continuous output, and owners consistently describe it as the quieter of the two even under load. If your loads are just phones, laptops, and small electronics, the RIVER 2 Max does that job for meaningfully less money and less weight, and the premium buys headroom you may never use.
Can either of these power a full weekend of camping or a home during a blackout?
Not solo. A typical weekend camping load runs around 2,100Wh and an 8-hour blackout around 1,645Wh, both well past what either unit holds in a single charge. Pair one with solar panels to stretch it, or look at a station sized for 2,100Wh or more if multi-day use is the actual plan.
Is the RIVER 2 Max loud?
Loud enough to notice under real load. EcoFlow's own spec sheet flags it as the louder of the two units here, and the Power 1000 stays close to silent doing the same work according to consistent owner reports. If it's running near where you sleep or work, weight that gap more heavily than the price difference.
Can I add a battery later if I outgrow either one?
No. Both are sealed, fixed-capacity units with no expansion battery or add-on tank. Buy the capacity that covers your needs now: the Power 1000's 1,024Wh ceiling is double the RIVER 2 Max's 512Wh, but neither grows past what's in the box.
Which one should I buy for a CPAP?
The Power 1000. Both hold enough charge for a full night. A CPAP draws roughly 320Wh, a fraction of either battery, so capacity was never the constraint. Noise is, and owners consistently describe the Power 1000 as the quieter of the two under load, which matters when the unit is a few feet from your head all night.
