Head-to-head test
EcoFlow RIVER 3 PLUS vs DJI Power 1000
The extra $440 doesn't buy a fancier version of the same battery — it buys one that's 3.6 times bigger and cheaper per watt-hour to boot, so the RIVER 3 PLUS's entire case is the $440 itself, plus 18.3 pounds you don't have to carry.

Spec deltas
$259 buys 286Wh from EcoFlow's RIVER 3 PLUS. $699 buys 1,024Wh from DJI's Power 1000 — 738Wh more, nearly 3.6 times the capacity, for nearly 2.7 times the price.
Here's the twist a straight price-per-Wh read would miss: the pricier unit is also the more efficient one. The Power 1000 costs $0.68 per watt-hour of capacity against the RIVER 3 PLUS's $0.91, and $0.17 per lifetime kilowatt-hour it will ever deliver against $0.30. This isn't a premium tax — it's the bigger battery, and it's also the cheaper one by the watt-hour.
Take the Power 1000 if $699 clears your budget: it wins on capacity, noise, cycle life, and the two modeled scenarios sized to actually finish, CPAP Overnight and Tailgate Party. Take the RIVER 3 PLUS if $699 doesn't, or if 18.3 fewer pounds matters more to you than any of that — that's a real, honest reason, just not a capability argument.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
Factor in that the Power 1000 is also rated for 1,000 more charge cycles, and the gap widens further across ownership: $0.17 per lifetime kilowatt-hour delivered against the RIVER 3 PLUS's $0.30. The RIVER 3 PLUS isn't the value pick on any energy basis here — it's the smaller, pricier-per-watt-hour option that happens to carry the lower sticker.
RIVER 3 PLUS: 286Wh for $259, or $0.91 per watt-hourPower 1000: 1,024Wh for $699, or $0.68 per watt-hour
Why it mattersAnyone shopping this pair purely on which one is cheaper should be pricing capacity, not stickers. On that basis, the $440-more unit is the bargain.
That's not a coincidence specific to CPAP machines or tailgate parties. The same ratio shows up in all six modeled scenarios on this page, because percent-used is just load divided by usable capacity — a fixed gap between two batteries produces the same relative overrun no matter what's plugged in. There's no scenario on this page hiding a data-backed reason to prefer the RIVER 3 PLUS.
RIVER 3 PLUS holds about 243Wh usable after inverter losses; Power 1000 holds about 870Wh usableCPAP Overnight (320Wh needed): RIVER 3 PLUS uses 132% of its usable capacity, Power 1000 uses 37%Tailgate Party (670Wh needed): RIVER 3 PLUS uses 276%, Power 1000 uses 77%
Why it mattersStop scenario-shopping for a reason to justify the cheaper unit on capability grounds. The gap is structural, so decide on price and weight honestly instead of hunting for the one use case where the numbers happen to look closer.
weight
The physical read stays honest either way: 10.4 lbs is a one-hand, off-the-shelf grab, and 28.7 lbs is a two-hand lift you plan for. That doesn't disappear because the density math favors the Power 1000. If the unit needs to fit in a backpack or go up a flight of stairs solo, the RIVER 3 PLUS's absolute weight is what your back feels, not its watt-hours per pound.
RIVER 3 PLUS: 10.4 lbs for 286Wh, about 27.5 watt-hours per poundPower 1000: 28.7 lbs for 1,024Wh, about 35.7 watt-hours per pound
Why it mattersBuyers who need genuine one-hand portability should still lean RIVER 3 PLUS regardless of the efficiency numbers. Buyers who load it into a vehicle once and won't carry it much further should let the density math override the raw weight number.
Only past 1,024Wh does the RIVER 3 PLUS's expansion path actually overtake the Power 1000's fixed capacity. Short of that threshold, buying into the expansion ecosystem is a more complicated way to arrive at capacity you could buy outright, already assembled, in the Power 1000.
RIVER 3 PLUS accepts EcoFlow expansion batteries; Power 1000 is fixed at 1,024Wh with no expansion pathRIVER 3 PLUS starts at 286Wh, 738Wh below the Power 1000's fixed capacity
Why it mattersOnly shop the RIVER 3 PLUS for its expansion path if you already know your ceiling is well past 1,024Wh. If you just want more than 286Wh and don't know your ceiling yet, the Power 1000 gets you there in one box.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The core economic story: cheaper to buy inverts to more expensive to own once cycle life and capacity are priced in.
cost / lifetime kWh
The RIVER 3 PLUS is the cheaper purchase by $440, but the Power 1000 is the cheaper unit to own. Price it per lifetime kilowatt-hour — every unit of energy either battery will ever deliver across its rated cycle life — and the Power 1000 comes out at $0.17 against the RIVER 3 PLUS's $0.30. That gap is wider than the sticker-price gap alone would suggest, because the Power 1000 wins twice over: more capacity (1,024Wh against 286Wh) and more rated cycles (4,000 against 3,000), and both differences compound in the same direction.
Cycled daily, that works out to roughly 11 years of service from the Power 1000 against about 8.2 from the RIVER 3 PLUS. The counterweight is real: at $52 per warranty-covered year against $140, the RIVER 3 PLUS is the better-protected dollar, even though both promises run exactly five years. If the unit sits mostly idle as blackout insurance rather than working for a living, that cheap warranty-year math matters more than a lifetime-kWh figure you'll rarely fully cash in.
Growth Path
Selected because: The RIVER 3 PLUS's headline expandable spec needs the myth-busting math before it means anything.
solar input
The RIVER 3 PLUS's expandability looks like a clean advantage until you check where it starts: 286Wh, some 738Wh below the Power 1000's fixed 1,024Wh. A first EcoFlow expansion battery is mostly spent catching up to capacity the Power 1000 already ships with in a single box, not growing past it.
The math only flips once your real ceiling sits meaningfully above 1,024Wh — at that point, and only at that point, the RIVER 3 PLUS's ability to keep adding batteries starts to matter more than the Power 1000's fixed, sealed capacity. Solar tells a similar story: the Power 1000 accepts up to 800W against the RIVER 3 PLUS's 200W, a 4 times wider intake for anyone actually planning to refill from panels rather than a wall outlet.
Your Life, Your Pick
Selected because: The Power 1000 sweeps both winnable scenarios, and the overrun ratio is constant across all six, which is itself the finding.
Two of six modeled scenarios are sized for a battery in this class to actually finish, and the Power 1000 takes both: CPAP Overnight (320Wh needed, Power 1000 uses 37% of capacity) and Tailgate Party (670Wh needed, 77%). The RIVER 3 PLUS overruns both instead of finishing them — 132% and 276% of its own usable capacity — meaning it doesn't just fall short, it isn't close.
The other four scenarios overrun both batteries, so neither wins them outright. What's notable is that the overrun ratio barely moves: the RIVER 3 PLUS needs roughly 3.6 times the share of its own capacity that the Power 1000 needs, in all six scenarios, camping and blackout included. That consistency means the gap is the battery, not the appliance list — there's no scenario on this page hiding a capability win for the cheaper unit.
What the Specs Don't Tell You
Selected because: Four cards fire and split unevenly: three nominal RIVER 3 PLUS wins that mostly wash out, one substantial Power 1000 win that doesn't.
rated cycles
Four cards fire, and three nominally favor the RIVER 3 PLUS, though two barely matter in practice. Its 10ms UPS switchover beats the Power 1000's 20ms, but both are fast enough that a desktop PC, router, or CPAP machine never notices either one. Its warranty costs $52 per covered year against $140 for the Power 1000 — a real number, but both warranties run the identical five years, so it's the sticker-price gap wearing a different label, not new information.
The real substance sits in the fourth card: the Power 1000's 4,000 rated cycles against 3,000 translate into years, not just a bigger spec number — roughly 11 years of daily use against 8.2. The expansion card nominally favors the RIVER 3 PLUS too, but as the growth-path math shows, it doesn't pay off until you're past 1,024Wh. Read honestly, this section is one substantial Power 1000 win and three RIVER 3 PLUS technicalities.
Brand Trust
Selected because: A long-established generalist against a two-year-old specialist, with a real trust trade-off worth naming on both sides.
EcoFlow is the established generalist here — the largest lineup in portable power, the largest community in the category, and years of ownership data across dozens of models. That scale comes with scale's problems: a late-2025 recall on a different, larger DELTA Max model, and a floated app-subscription plan the company walked back after user pushback. Neither touches this specific unit directly, but both are part of what you're buying into with the brand.
DJI is the two-year-old specialist, leaning on a drone-repair network and battery patents built for a different product category. It has no dedicated power-station community yet and no expansion ecosystem at all — this 1,024Wh is the permanent ceiling. That youth is a real, if modest, risk, and it's the reason DJI's case has to be won on the spec sheet in front of you rather than on a decade of owner track record.

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 two-night camping load of about 2,100Wh overwhelms both batteries. The RIVER 3 PLUS would need to drain more than 8 times its usable capacity to cover it; the Power 1000 needs a bit over 2.4 times its own. Neither is sized for this alone — solar input or a shorter appliance list closes the gap faster than switching between these two.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
An overnight blackout running a fridge, router, and lights needs about 1,645Wh. The RIVER 3 PLUS falls well short, needing nearly 7 times its usable capacity; the Power 1000 comes up short too, needing almost twice its own. This calls for a bigger class of unit or a supplemental battery, not either box as it ships.

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
An overnight CPAP run needs about 320Wh. The RIVER 3 PLUS's usable capacity doesn't stretch that far, while the Power 1000 covers the night on well under half its capacity and finishes with plenty still in reserve. For a bedside medical device, that reserve margin is the entire point.
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 off-grid workday — laptop, monitor, router — needs about 910Wh. The RIVER 3 PLUS isn't close, and even the Power 1000 slightly overruns its own usable capacity here. Both point to the same fix: a wall or solar top-up partway through the day, or a bigger unit if this is a regular routine rather than an occasional one.
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 game-day setup — speaker, TV, blender for drinks — draws about 670Wh over the afternoon. The RIVER 3 PLUS can't cover it alone, needing nearly three times what it holds; the Power 1000 handles it comfortably on well under its full capacity, with plenty left for the drive home.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
A full day of van life — a fridge running around the clock, plus a laptop, lights, and a fan — needs about 4,685Wh. Both units are the wrong category for this alone: the Power 1000 would need refilling several times over, and the RIVER 3 PLUS closer to twenty. Daily van life is an argument for a larger fixed-capacity unit or a real solar array, not a choice between these two.

Conclusion
July 28, 2026
Verdict: the Power 1000, on Power Score margin
Buy the Power 1000 if $699 fits the budget. It has 738Wh more capacity, costs less per watt-hour ($0.68 against $0.91) and less per lifetime kilowatt-hour ($0.17 against $0.30), runs quieter (23dB against 30), and is rated for 1,000 more charge cycles — and it's the only one of the two that actually clears the CPAP-overnight and tailgate-party scenarios modeled on this page, not just approaches them. The RIVER 3 PLUS answers with a real case of its own: it costs $440 less, weighs 18.3 fewer pounds, and its 10ms UPS switchover edges the Power 1000's 20ms, though both are fast enough that neither a router nor a CPAP machine notices the difference. Its expansion batteries look like an equalizer but mostly aren't — a first one mostly buys back capacity the Power 1000 already ships with, and the path only pulls ahead once you'd need more than 1,024Wh. Take the Power 1000 if the price clears; take the RIVER 3 PLUS if $699 is a hard ceiling or the extra pounds are the actual dealbreaker, not the price.

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 PLUS rates 5.0/5 (99th percentile of 22 Personal-class units), and Power 1000 rates 3.9/5 (35th percentile of 24 Everyday-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Expandable, But Behind Before It Starts
The RIVER 3 PLUS accepts EcoFlow's own expansion batteries; the Power 1000 is a sealed 1,024Wh unit with no add-on path. That sounds like a clean win for the RIVER 3 PLUS until you note its starting point: 286Wh, which is 738Wh behind the Power 1000 before you've added anything. A first expansion battery mostly buys back capacity the Power 1000 already ships with. The expansion path only pulls ahead once your ceiling is well past 1,024Wh.
Ten Milliseconds Against Twenty
The RIVER 3 PLUS switches to battery in 10ms, a line-interactive spec; the Power 1000 takes 20ms, standby-class. Both are fast enough to be invisible to a desktop PC, a router, or a CPAP machine — the gap only matters for equipment that can't tolerate any interruption at all, which is a small slice of what either unit is bought to run.
Same Five Years, Priced Differently
Both units carry a 5-year warranty, so the only variable is what that coverage costs: $52 per covered year for the RIVER 3 PLUS against $140 for the Power 1000, which works out to 19.3 years of coverage per $1,000 spent against 7.2 — 2.7 times more warranty per dollar for the RIVER 3 PLUS. It's real, but it's the sticker-price gap doing the work; the warranty term itself is identical on both sides.
4,000 Cycles Against 3,000
The Power 1000 is rated for 1,000 more charge cycles than the RIVER 3 PLUS. Cycled daily, that's roughly 11 years of service against about 8.2; cycled about twice a week, it stretches toward 38 years against 29. Past the rated count, neither battery quits outright — both settle to roughly 80% of original capacity, which is still a usable battery, just a smaller one.

Ecosystem
The largest lineup in portable power — a dozen-plus models spanning DELTA Pro, DELTA 3, and RIVER 3, plus solar panels and home energy panels. If you outgrow this unit, the next size up is already in the catalog.
Support
US-based phone, email, and chat support. The record is split — plenty of hassle-free prepaid-label replacements, but also long waits and refurbished swaps on some claims. Buying through Costco or Amazon adds a return safety net worth having.
Community
The biggest community in the category by a wide margin — a large dedicated forum presence across Reddit and Facebook, plus an official community. If something goes wrong, someone else has probably already posted the fix.
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
Fastest charging tech in its own lineup and the deepest ecosystem to grow into, up to whole-home modular systems.
Worth knowing
A late-2025 recall on a different, larger DELTA Max model (overheating risk) is worth knowing about the brand generally, even though it doesn't touch this unit. EcoFlow also floated a paid-subscription tier for app features before backing off after user pushback.
DJI
Ecosystem
A new line — four power station models total, launched starting in 2024. There's no accessory shelf to speak of yet beyond the stations themselves.
Support
Inherits DJI's established global repair network from its drone business, with a generally good reputation, but almost no power-station-specific track record to judge it by yet.
Community
No dedicated power-station community exists yet. What discussion there is happens inside DJI's much larger, mostly drone-focused 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
The quieter of the two, drone-derived battery engineering with a deep patent portfolio behind it, and proprietary fast-charge ports for DJI drone batteries.
Worth knowing
Solar panels need a separate proprietary DJI adapter — there's no built-in charge controller. And there's no expansion-battery ecosystem at all, so this 1,024Wh is the ceiling.
Analyst note
This is an established generalist against a two-year-old specialist. EcoFlow's case is scale: more models, a bigger community, more places for something to go right or get fixed. DJI's case is focus: one new product line built on drone-grade battery engineering, without the years of ownership data to back it up yet. Neither brand risk is severe enough to override the hardware case above, but it's a real reason DJI needs to win on the numbers, since it can't yet win on track record.
Growth path
RIVER 3 PLUS
EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 286Wh.
Accepts up to 200W of solar. Limited to a single portable panel.
Adequate ports for most setups, but heavy users may want a power strip.
Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.
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
Don't read the RIVER 3 PLUS's expandability as a straight win here: it starts at 286Wh, below the Power 1000's 1,024Wh, so a first expansion battery largely buys back capacity the Power 1000 already includes. It only pulls ahead if you'd grow past 1,024Wh — short of that, the Power 1000's larger fixed capacity is the simpler value.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 3 PLUS
Independent coverage of the RIVER 3 PLUS converges on the same handful of points: it's genuinely quiet, staying under 30dB in a way reviewers call remarkableA2, and it's light enough to be called highly portable at 10.4 lbs — a small-format station whose 1,200W X-Boost surge can still briefly run higher-draw kitchen gear like a coffee maker or microwaveA3. It ships with a real 600W inverter, not a token oneA1.
The pack underneath is straightforward LiFePO4 chemistry rated for 3,000 cyclesA4, the same class of cells EcoFlow uses across the RIVER 3 line. Nothing in this coverage raises a flag, but it leans on review-site testing rather than long-term owner forums, so treat the durability read as promising rather than proven.
“286Wh base, expandable to 572Wh (EB300) or 858Wh (EB600), with a genuine 600W inverter (1,200W X-Boost) and 220W solar input — twice the inverter and solar of the base RIVER 3.”

DJI Power 1000
Reviewers keep landing on the same word for the Power 1000: quiet. It's described as one of the quietest stations in its class, staying nearly silent through normal loads and only announcing itself as a soft whoosh once you push it hardB1. Testers who deliberately ran it past its rated output for a sustained stretch reported no shutdowns and no loud complaints from the fanB2, and even a full-speed wall charge reportedly leaves the fan barely audibleB3.
In the field it held up over a week of camping — a compressor fridge, phones, laptops, and lights running the whole time — and drone pilots single it out for fast-charging flight batteries while it powers everything else at onceB4. This is a newer product line than EcoFlow's, so the record is shorter, but what exists so far is consistently positive.
“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.”

“AC charging takes about 70 minutes from 0% to 100% (about 50 minutes to 80%), and during full-speed charging the fan barely makes a sound.”

“Over a week-long camping trip it powered a 45W compressor fridge, phones, laptops, and LED lights; it's also a favorite of drone pilots for fast-charging DJI batteries while running other devices.”

Who Should Buy Which
Buy the RIVER 3 PLUS if you…
- →The $699 Power 1000 is simply outside the budget, and $259 for 286Wh covers what you actually run — phones, lights, a laptop, small stuff, not an overnight CPAP or a blackout fridge run.
- →It needs to be a one-hand carry. At 10.4 lbs against the Power 1000's 28.7, this is the unit you grab off a shelf without thinking about it, not one you plan a lift around.
- →You already know your ceiling is well past 1,024Wh and you're building toward it with expansion batteries from day one — that's the one path where expandable actually pays off.
Buy the Power 1000 if you…
- →The real use case is an overnight CPAP run or a multi-hour tailgate — the two scenarios modeled on this page that a unit this size can actually finish, and the Power 1000 clears both with capacity to spare while the RIVER 3 PLUS doesn't come close.
- →Noise matters — a bedroom, a quiet campsite, a shared space. 23dB against 30 is a real, spec-sheet difference, not a marketing one.
- →You're pricing this by the watt-hour, not the sticker. At $0.68 per watt-hour and $0.17 per lifetime kilowatt-hour, it's the better deal on both counts despite costing $440 more upfront.
If neither fits
If the real job is an 8-hour blackout with a fridge running, a full remote workday off-grid, or a full day of van life, both of these are the wrong category. The blackout load alone, about 1,645Wh, overruns the Power 1000's usable capacity, let alone the RIVER 3 PLUS's, and van life, about 4,685Wh, overruns both several times over. That calls for a bigger fixed-capacity unit, an expansion battery bought on day one, or a real solar array, not a choice between these two.
The Bottom Line
Take the Power 1000 if $699 clears your budget. It has 738Wh more capacity, costs less per watt-hour delivered ($0.68 against $0.91) and less per lifetime kilowatt-hour ($0.17 against $0.30), runs quieter, and is the only one of these two that actually finishes the CPAP-overnight and tailgate scenarios modeled on this page rather than just approaching them.
The RIVER 3 PLUS's case is real, just narrower than expandable makes it sound: $440 less at checkout, 18.3 fewer pounds to carry, and an expansion path that only pays off once your needs pass 1,024Wh. If that's your actual ceiling, or if $699 simply isn't in the budget, buy the RIVER 3 PLUS and don't second-guess it. Otherwise, the Power 1000 is the better machine and, watt-hour for watt-hour, the better deal too.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DJI Power 1000 worth $440 more than the EcoFlow RIVER 3 PLUS?
If $699 fits your budget, yes. The Power 1000 isn't just a bigger battery — it's a cheaper one per watt-hour, $0.68 against the RIVER 3 PLUS's $0.91, and cheaper per lifetime kilowatt-hour too, $0.17 against $0.30. It also runs quieter and clears the CPAP and tailgate scenarios modeled on this page outright. The RIVER 3 PLUS's case is the $440 saved and 18.3 fewer pounds to carry, not equal capability at a discount.
Can the RIVER 3 PLUS run a CPAP machine all night?
Not on its own. An overnight CPAP run needs about 320Wh, and the RIVER 3 PLUS's usable capacity comes in under that, so it runs out before morning. The Power 1000 covers the same night using well under half its capacity and finishes with plenty in reserve.
Does the RIVER 3 PLUS's expandable battery make it the smarter long-term buy?
Only if you already know you'll need more than 1,024Wh eventually. It starts at 286Wh, 738Wh below the Power 1000's fixed capacity, so a first expansion battery mostly buys back ground the Power 1000 already covers in one box. Short of that 1,024Wh threshold, the Power 1000's larger fixed capacity is the simpler, cheaper-per-watt-hour path to more power.
Which is quieter, the RIVER 3 PLUS or the Power 1000?
The Power 1000, by spec: 23dB against the RIVER 3 PLUS's 30dB. Reviewers also describe the Power 1000 as one of the quietest units in its class even under load, while the RIVER 3 PLUS's sub-30dB operation is itself called remarkable by reviewers — both are quiet units, but the Power 1000's number is the lower one.
Can either one power a fridge through an overnight blackout?
Not fully, no. An 8-hour blackout running a fridge, router, and lights needs about 1,645Wh, more than either battery's usable capacity, with the RIVER 3 PLUS falling shorter than the Power 1000. Both switch over fast enough, 10ms and 20ms, that the fridge won't notice the grid dropped, but neither one gets you through the whole night without a recharge.
