Spec deltas
$1,299 against $7,999, and 48.5 lb against 298.7 lb. These two aren't competing for the same buyer, and the most useful thing this page can do is tell you which buyer you are.
The DELTA Pro Ultra X is a whole-home system. It runs 12,000W continuous at 120/240V with surge handling to 45,000W, enough to carry every circuit including a 5-ton air conditionerA1, and the quick-connect install EcoFlow advertises still takes about seven daysA4. It wins five of the six load scenarios on this page, and it should: 12,288Wh against 2,048Wh is exactly six times the tank. What that sweep doesn't tell you is that two of those wins involve a 298.7 lb appliance notionally attending a tailgate.
The Power 2000 is the right buy for almost everyone who lands here. It covers the blackout, the workday, the CPAP night and game day, one person can put it in the back of a car, and the gap between $1,299 and $7,999 is $6,700 that buys a lot of other things. Where it stops is the second night unplugged, and that limit is worth knowing before you click.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
So the price gap isn't buying cells. It's buying one 12,000W inverter that speaks 240V and can take a well pump or a 5-ton ACA1, where the six-box version is six separate 3,000W islands with their own outlets. Identical energy, completely different machine.
DELTA Pro Ultra X: $7,999 for 12,288WhPower 2000: $1,299 for 2,048WhDELTA Pro Ultra X delivers 12,000W continuous at 120/240V, surge to 45,000W, rated to carry whole-house circuits including a 5-ton ACA1
Why it mattersIf your problem can be solved with extension cords, you're buying a capability you'll never switch on; if your problem is a breaker panel, no number of Power 2000s solves it.
What rescues it is refill speed rather than reserve: about 75 minutes to full from 1,800W of solarB1 means a sunny second morning resets the tank before lunch. A January outage with three overcast days doesn't offer that morning, and 96Wh of spare capacity is not a plan.
8-Hour Blackout needs 1,645Wh; the Power 2000 has 1,741Wh usable, leaving 96WhWeekend Camping needs 2,100Wh; the Power 2000 is 359Wh short1,800W solar input, a full solar charge in about 75 minutesB1
Why it mattersBuy the DJI if your outages come with sun, a running car, or a grid that returns within a day; if they come with snow, stop comparing these two and price capacity instead.
solar input
It's buying the right to point a rooftop array at the thing. 10,000W of panels is not four folding units in a field, and the box they feed is a 298.7 lb two-person lift that takes about a week to commissionA4. The solar ceiling and the install week are the same fact wearing two hats: this is a house system.
DELTA Pro Ultra X: 10,000W solar input into 12,288WhPower 2000: 1,800W solar input into 2,048WhDELTA Pro Ultra X weighs 298.7 lb and installs over about seven daysA4
Why it mattersIf you don't own the roof, renters and van dwellers included, the EcoFlow's biggest advertised number is one you can't spend.
continuous output
That gap is smaller than it sounds for ordinary loads and larger than it sounds for one buyer: the person shopping specifically to start a compressor. Hands-on reports that it took everything thrown at itB4 are encouraging, but an electrician can't size a circuit off an impression.
Power 2000: 3,000W continuous output, with no published surge figure in our recordDELTA Pro Ultra X: 12,000W continuous with surge to 45,000WA1Reviewers report the Power 2000 handled surges consistently across their testingB4
Why it mattersIf you're buying to start one known, difficult motor, resolve the Power 2000's startup headroom with DJI before you order, or buy the unit that publishes the number.
The specific dimensions that decide these two units — everything else is a tie.
Portability & Form Factor
Selected because: One of these gets installed and the other gets carried: 298.7 lb against 48.5 lb.
weight
48.5 lb is a suitcase you're mildly annoyed about. 298.7 lb is a delivery. The DJI has a handle and a slot in the back of a car; the EcoFlow is a two-person lift you position once and then live with, and even the quick-connect install EcoFlow markets runs about seven daysA4.
That isn't a trade you weigh against capacity. It's a fork. If this needs to go in a van, on a boat, to a campsite, or into a friend's basement next weekend, the EcoFlow isn't heavy, it's disqualified. If it's going to sit beside a breaker panel for a decade, the DJI's 48.5 lb stops being a feature and goes back to being a smaller battery.
Your Life, Your Pick
Selected because: The Power 2000 clears four of the six modelled loads and misses two, and the model has no category for a unit that gets wired in place.
Our scenario model has no category for an installed system. Weekend Camping and Tailgate Party score every unit as though it drove itself there, and the scoring explicitly rewards the lighter box, so a 298.7 lb wired appliance can sweep them while being the wrong purchase. The DELTA Pro Ultra X wins five of six here. Treat two of those wins as arithmetic rather than advice.
The scenarios that carry information are the ones the Power 2000 fails or barely survives. It clears the 1,645Wh blackout with 96Wh left of 1,741Wh usable, misses the 2,100Wh camping weekend by 359Wh, and misses the 4,685Wh van-life day by 2,944Wh. Those usable figures come from a flat 85% derate this site applies to every unit's nameplate, so read them as planning numbers rather than measurements. Read as a set, the answer is clean: one night unplugged, yes. Two nights, no. That line has nothing to do with which unit is better.
Runtime: Will It Power Your Gear?
Selected because: 12,288Wh against 2,048Wh is exactly six times the tank, for $7,999 against $1,299.
continuous output
12,288Wh against 2,048Wh is exactly six times the tank, and storage is the only spec on this page that scales cleanly with the price. Everything else about the EcoFlow, the 12,000W continuous rating, the 45,000W of surge headroom, the 240V output, is inverter and wiring rather than battery.
For load sizing there's one asymmetry worth naming. The EcoFlow publishes a continuous figure and a surge figure, so you can size it against a specific motor on paperA1. We have no published surge figure for the Power 2000, so plan against its 3,000W continuous rating and nothing else. Reviewers report it took every load they put on it without complaintB4, which is reassuring and is not the same thing as a number.
Lifetime Value
Selected because: $0.19 per lifetime kWh against $0.16 is close enough to settle nothing, and the years column settles less.
cost / lifetime kWh
Cost per lifetime kWh lands at $0.16 for the DJI and $0.19 for the EcoFlow, and three cents shouldn't move anyone. The years-of-life row is the one to distrust: 3,500 cycles renders as 9.6 years of daily use and 4,000 cycles renders as 11, and the calculation never asks how much energy a cycle actually moves. One of those cycles moves 12,288Wh and the other moves 2,048Wh, six times the work for the same tick of the counter.
Which makes this table decorative for a pair this mismatched. Neither number is wrong; both are answering a question nobody standing between a $1,299 portable and a $7,999 installed system is asking.
Growth Path
Selected because: Both take expansion batteries, so the question isn't whether you can grow but what you can plug in.
solar input
Both take expansion batteries, so neither is a dead end, and the recommendation the engine reaches here is the right one for once: the difference is intake. One of these can absorb a rooftop array; the other takes folding panels. If your growth plan involves more sun, that's the deciding fact.
Two catches before you plan around it. The Power 2000 has no onboard solar charge controller, so panels reach it through DJI's own adapter, which is a cost and a dependency rather than a dealbreaker. And the published figures for the DELTA Pro Ultra X's expansion ceiling don't agree with each other across our sourcesA2, so we're not printing one. What we can say is that the ceiling is a multi-inverter, many-battery configuration, not the $7,999 base unit that arrives on the truck.

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
2,100Wh across the weekend, and the Power 2000 has 1,741Wh usable, so it comes up 359Wh short. One night with a fridge running it does comfortably. The second night is where it stops. The DELTA Pro Ultra X finishes the whole weekend at 20% used.

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
DELTA Pro Ultra X
Both make it through. The Power 2000 lands with 96Wh spare out of 1,741Wh usable, which is a pass rather than a margin, while the DELTA Pro Ultra X finishes at 16% used with the following night still in the tank. If your outages have a habit of running long, that difference is the entire argument.
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
320Wh for the night, and both cover it several times over, so capacity decides nothing here. Noise won't decide it either, because both units are rated 30 dBA. What's left is placement and price: at 48.5 lb and $1,299 the Power 2000 goes on the bedroom floor, while the DELTA Pro Ultra X is a fixed 298.7 lb appliance at the end of an extension cord.
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
DELTA Pro Ultra X
910Wh for the day, and the Power 2000 ends it at 52% used. That's one workday, not two, unless it charges overnight. The DELTA Pro Ultra X ends at 9% and never gives it a thought.
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 2000
670Wh is a light afternoon and both walk it, the Power 2000 at 38% used. The win goes to the bigger battery because capacity is what's being scored, and capacity is the one thing a parking lot never tests.

Van Life Daily
A full day of mobile living — the ultimate endurance test
DELTA Pro Ultra X
4,685Wh a day is where the Power 2000 stops being a candidate. It's 2,944Wh short, and careful use doesn't close a gap that size. The DELTA Pro Ultra X covers the day at 45% used.

Conclusion
August 9, 2026
Verdict: the DJI Power 2000
Buy the DJI Power 2000 at $1,299 unless you are wiring a breaker panel. It covers the eight-hour blackout, the remote workday, the CPAP night and the tailgate load, it weighs 48.5 lb, and a full solar refill from 1,800W of panels takes about 75 minutesB1. The DELTA Pro Ultra X is the better machine by every capacity number here, 12,288Wh of storage behind a 12,000W 120/240V inverter with surge handling to 45,000WA1, and none of that is relevant to a buyer who hasn't already decided to spend $7,999 on a fixed installation. Where the DJI genuinely stops is the second day off-grid: it misses the 2,100Wh camping weekend by 359Wh and the 4,685Wh van-life day by 2,944Wh. If that's your load, the answer is a bigger portable, not a house system.

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, DELTA Pro Ultra X rates 4.3/5 (61st percentile of 29 Whole-Home / Off-Grid-class units), and Power 2000 rates 4.3/5 (56th percentile of 26 Large-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
298.7 lb: You Place It Once
Two people, bent knees, and a decision about where it lives, because it isn't coming back out. This is a 298.7 lb appliance with an install measured in days, not a box you reposition when the furniture moves. Measure the doorway and the turn at the bottom of the stairs before delivery, not after. The DJI beside it is 48.5 lb: one person, one trip.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The Power 2000's figure is a maximum rather than a guarantee — it depends on buying from DJI's own store, which is where the full five years is advertised. Worth saying because the per-dollar framing can suggest otherwise: the Power 2000 works out at 3.8 years of cover per $1,000 spent against the DELTA Pro Ultra X's 0.6, but that spread is the price gap, not the terms.

Analyst note
Both units have similar long-term ownership costs ($0.19/kWh vs $0.16/kWh). The price difference is what you see on the sticker — neither is a hidden bargain or rip-off. One caution on the lifespan row: the Power 2000 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the DELTA Pro Ultra X still delivers more over its shorter horizon (43,008 vs 8,192 kWh). Years measure wear, not usefulness.
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
X-Stream fast charging, the deepest catalogue in portable power, and the fastest release cadence in the category. The DELTA Pro Ultra X scales well past its 12,288Wh base by stacking inverters and batteries, though published figures for the ceiling disagree with each other, so we won't quote one.
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 to power stations in 2024, with a short line: the Power 500, the Power 1000 and its V2 refresh, the Power 1000 Mini, and this Power 2000 at the top.
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
Quiet and quick to refill. This unit is rated 30 dBA, and 1,800W of solar input against a 2,048Wh pack is a full refill in a bit over an hour. Behind it sits 700+ battery patents from the drone business, SDC ports that charge DJI drone batteries directly, and LFP cells rated for 4,000 cycles.
Worth knowing
A recent entrant to power stations, arriving long after the established players, so there is less long-term field data than for EcoFlow, Jackery or BLUETTI — though DJI brings a deep hardware track record from drones. No built-in solar charge controller (requires a separate proprietary adapter). SDC ports are proprietary to the DJI ecosystem, so their fast-charging advantage mostly benefits people who already own DJI gear. Battery expansion is available on the newer Power 2000 and Power 1000 V2, but not on the earlier Power 1000 or Power 500 — check the specific model.
Analyst note
EcoFlow brings the deeper catalogue and the larger user community; DJI arrived in power stations in 2024 with a much longer track record in batteries from another business entirely. On a $1,299 portable that trade is easy to make. On a system you wire into a panel and expect to keep servicing long after the 5-year warranty lapses, time spent in this specific category is worth more than it looks.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA Pro Ultra X
There is no owner record for the DELTA Pro Ultra X. Every entry in our file traces to EcoFlow's own material and launch-window reviews: the 12kW whole-home output with surge handling to 45kWA1, the expansion configurationsA2, the EV-grade LFP cells with 24/7 BMS oversightA3, and the CES 2026 Innovation Award alongside a quick-connect install rated at about seven daysA4. That tells you what the system is designed to do and nothing about what it does in year three.
One thing to name plainly: the entry describing the expansion range is a platform-level claim spanning several inverter and battery configurationsA2, not a description of the base unit you'd actually receive. If you're buying this because of the top-end capacity figure, you are also buying additional inverters and a rack of batteries to get there.
“Base config delivers 12kW continuous at 120/240V — enough to power every circuit including a 5-ton AC — scaling to 12-36kW with surge handling to 45kW via Adaptive Start.”

DJI Power 2000
Field evidence on the Power 2000 is review-desk work rather than long ownership, and it's consistent. About 29 dB at five feet when the fan engages, and still among the quietest units tested under heavy loadB2. A full wall charge in roughly 90 minutes, with some testers measuring closer to an hour, and about 75 minutes from 1,800W of solarB1. A build described as eightfold protection with 26 temperature sensors, 21 fuses and structural reinforcement rated to a one-ton static loadB3.
The most useful reviewer note for a buyer is that it ran everything put in front of it and handled startup surges consistentlyB4. That's the closest thing to a surge answer we have, and it's a hands-on impression, not a rating. Nobody in this file has owned one long enough to say how it ages.
“Among the fastest-charging tested — a full wall charge in about 90 minutes (reviewers measured even faster, roughly an hour), and up to 1,800W of solar input for a full solar charge in about 75 minutes.”

What owners complain about
With the expansion battery he only gets 2800Wh on DC.

DJI told him all Power 2000 units have an EMI issue with no fix; his Mac Mini coil-whined.

3600W surge is not bad but lower than some comparable units.

What owners praise
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 DELTA Pro Ultra X if you…
- →You're backing up a breaker panel rather than a power strip: 120/240V, well pump, a 5-ton air conditioner, the whole boardA1.
- →You own the roof and intend to put a real array on it. This is the only one of the two that can absorb 10,000W of solar.
- →You've already made peace with a 298.7 lb two-person lift that gets placed once, commissioned over about a weekA4, and never moves again.
Buy the Power 2000 if you…
- →You want one box ready for the next power cut. The 1,645Wh blackout is covered, for $1,299.
- →You're the one loading it. 48.5 lb into the back of a car, no second person and no appointment.
- →You already fly DJI, in which case the SDC ports charging drone batteries directly is a real reason to prefer it over an equivalent rivalB4.
If neither fits
If your actual load is a two-day camping weekend or a full van-life day, both of these are the wrong answer. The Power 2000 is 359Wh and 2,944Wh short of those two respectively, and the fix isn't a $7,999 installed system, it's a portable one class up: something that covers 4,685Wh in a box you can still lift into a vehicle.
The Bottom Line
Buy the Power 2000. Six of them hold the same 12,288Wh as one DELTA Pro Ultra X and cost less doing it, which tells you what the extra money on the EcoFlow is actually for: a 12,000W, 120/240V inverter wired into your houseA1, and the week of installation that goes with it. If that isn't the problem you have, it isn't the box you need.
The line to watch is the second night. One night unplugged, the DJI is comfortable. Two nights, or a full van-life day, and it's short by amounts no amount of careful rationing closes, and the answer there is a bigger portable rather than a wired system. Work out which side of that line you're on, then spend accordingly.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DJI Power 2000 enough to get through a power outage?
For the eight-hour outage we model, 1,645Wh of fridge, lights, router and devices, yes, with 96Wh left of its 1,741Wh usable. That's a pass rather than a cushion. If your outages tend to run overnight into a second day, plan on recharging it mid-outage instead of riding it out.
Why is the DELTA Pro Ultra X six times the price of the Power 2000?
Because the money isn't going into cells, even though you do get exactly six times the capacity at 12,288Wh against 2,048Wh. It buys a 12,000W inverter that puts out 120/240V and can carry whole-house circuits, plus the installation. Six Power 2000s would match the stored energy for less cash and still couldn't run a 240V well pump.
What is the surge rating on the DJI Power 2000?
We don't have a published surge figure for it, so size your loads against the 3,000W continuous rating and treat anything above that as unverified. Reviewers report it handled startup surges consistently across their testing, which is encouraging but isn't a number you can hand to an electrician. If you're buying specifically to start a large compressor, resolve that before you order.
Can I move the DELTA Pro Ultra X after it's installed?
Realistically, no. It's 298.7 lb, which is a two-person lift, and the install itself runs about seven days. Decide where it lives before it arrives, and check the route to that spot for stairs you'd regret.
Which one is cheaper to own over its lifetime?
The DJI, marginally: $0.16 per lifetime kWh against $0.19, off 4,000 cycles versus 3,500. Three cents per kWh isn't a reason to choose either. Ignore the years-of-life figures while you're there, because 9.6 years against 11 is just those cycle counts rescaled, with no account of the fact that an EcoFlow cycle moves 12,288Wh and a DJI cycle moves 2,048Wh.
