Head-to-head test
EcoFlow DELTA 3 Ultra vs DJI Power 2000
Same $1,299 either way: the EcoFlow stores half again as much energy, the DJI puts it back more than twice as fast from the sun, and whether panels are riding along settles which of those you actually need.

Spec deltas
The DELTA 3 Ultra and the Power 2000 both list at $1,299, and one of them holds 1,024Wh more than the other. That isn't a tiebreak, it's the whole argument: 3,072Wh against 2,048Wh for the same money, the same 4,000-cycle cells, and the same five-year warranty.
What DJI sells you instead is 23.6 pounds and a much faster refill. The Power 2000 swallows 1,800W of solar against the Ultra's 800W ceiling, so the smaller pack fills more than twice as fast from the same sun.
Divide either one out and they land within half a watt-hour per pound of each other, around 42. There's no packaging advantage hiding in the DJI; there's just less inside it. Which makes this a plain question about what you intend to carry, and unless panels are coming along, more is the right answer.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
weight
The DJI's 23.6 lb advantage is subtraction, not cleverness. At an identical $1,299 that shows up as $0.63 per watt-hour instead of $0.42, which is what you pay for the privilege of carrying 1,024Wh less.
Both units list at $1,299DELTA 3 Ultra: 3,072Wh at 72.1 lbPower 2000: 2,048Wh at 48.5 lbCost per watt-hour: $0.42 for the Ultra, $0.63 for the Power 2000
Why it mattersIf you pick the Power 2000, pick it because you genuinely won't carry 72.1 lb, not because lighter reads as better engineered.
solar input
That inverts the capacity argument, but only if you've bought your way to it. Enough panel to feed 1,800W is a substantial purchase on top of the station, and DJI's input needs its own adapter because there's no charge controller inside. Under clouds, or with one folding panel in the trunk, the Power 2000 is simply the unit with 1,024Wh less.
DELTA 3 Ultra solar input caps at 800WPower 2000 accepts up to 1,800W of solarReviewers measured a full solar charge on the Power 2000 in about 75 minutesB1DJI ships no built-in solar charge controller and requires a separate proprietary adapter
Why it mattersIf you already own a large array, the DJI's smaller tank stops mattering by lunchtime. If solar is a someday plan, buy the capacity now.
continuous output
The Power 2000 is very likely fine, and the field reports say exactly thatB4. But 'very likely fine' and a printed 7,200W are different purchases when the load on the list is a well pump or a window air conditioner. The Ultra's number is checkable before you spend the money. The DJI's has to be taken on someone else's bench.
DELTA 3 Ultra: 3,600W continuous with 7,200W of surge publishedPower 2000: 3,000W continuous, with no surge figure on its spec sheetReviewers report it ran everything they threw at it and handled surges consistentlyB4
Why it mattersIf a compressor load is the reason you're buying at all, the published headroom is worth the extra 23.6 lb.
Capacity
Expandability only starts paying above 3,072Wh, and above that line the Power 2000 is the only unit here that can get there at all, because the Ultra's growth path is a second Ultra. Below that line you'd be buying the same kilowatt-hours twice, on cells that carry the identical 4,000-cycle rating either way.
The Power 2000 accepts DJI expansion batteries; the DELTA 3 Ultra is fixed at 3,072Wh with no expansion portThe Power 2000's base capacity is 2,048WhBoth are rated for 4,000 cycles and carry five-year warranties
Why it mattersIf your loads are genuinely climbing toward RV or off-grid territory, the DJI is the only one of the two with a road. If they'll stay a house-during-an-outage load, that road is just a longer way to 3,072Wh.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: Both units cost $1,299, so the 1,024Wh capacity gap and the 800W-versus-1,800W solar gap are the only things left to weigh.
continuous output
A kilowatt-hour is a night, not a spec-sheet increment. The extra 1,024Wh on the EcoFlow side is a fridge running while you sleep, or a CPAP and a fan and a phone with margin left at breakfast, and it costs nothing extra because the two prices are the same.
The refill story runs the other direction and runs hard. The Ultra tops out at 800W of solar input, so filling 3,072Wh from empty is just under four hours of strong sun. The Power 2000 takes 1,800W into a smaller pack, which puts it back in a fraction of a good solar morning. One of these units spends the day charging. The other is done before you've broken camp.
Your Life, Your Pick
Selected because: The weekend-camping load lands at 2,100Wh, which is more than the Power 2000's 2,048Wh label holds.
The camping weekend is where this stops being abstract. Our model puts two nights at 2,100Wh. The Power 2000's label reads 2,048Wh. It's behind before the inverter takes its cut, which is why it comes out at 121% of what it can actually deliver while the Ultra sits at 80% and finishes the trip with a morning in reserve.
Everywhere else the pattern holds without drama. An eight-hour blackout costs the Ultra 63% and the DJI 94%, which are two very different mornings. A CPAP night is a dead heat at 12% and 18%, because neither unit notices 320Wh. And the van-life load asks for 4,685Wh a day, which neither of these can serve. That one isn't close for either box.
Portability & Form Factor
Selected because: 23.6 lb separates these two, and weight is the one thing extra capacity can't buy back.
weight
72.1 lb is a bent-knees, both-hands, find-someone-for-the-stairs lift. 48.5 lb is a suitcase you'd rather not carry far. Written down, 23.6 lb sounds like a rounding error. In practice it's the entire difference between a unit that moves whenever you want it to and one that moves when you've planned for it.
The honest version: if the Ultra lives in one spot and comes out during outages, its weight costs you almost nothing, roughly twice a year. If it's going in and out of a trunk every Friday, you'll resent it by October, and no amount of extra capacity fixes a lift you've quietly decided not to make.
Growth Path
Selected because: Only the Power 2000 takes expansion batteries, and it starts 1,024Wh below the capacity it would be expanding toward.
solar input
Only one of these grows, and it grows from behind. The Power 2000 accepts DJI expansion batteries. The DELTA 3 Ultra is a sealed 3,072Wh box with no expansion port at all. But look at where the DJI starts: its first added battery is largely a second purchase to reach the capacity the Ultra ships with, at the same $1,299.
That's not an argument against expandability. It's an argument about the line where expandability starts paying. Above 3,072Wh the Power 2000 is the only unit here with anywhere to go, since the Ultra's upgrade path is another Ultra. Below it, you're paying twice for kilowatt-hours you could have had once.
Lifetime Value
Selected because: Identical price, identical 4,000 cycles and identical five-year warranties mean the whole cost-per-kilowatt-hour gap is the capacity gap wearing a different hat.
cost / lifetime kWh
Eleven cents a kilowatt-hour against sixteen, over 4,000 cycles each. That figure isn't independent evidence and it's worth saying so out loud: same price, same cycle rating, same five-year warranty means the lifetime-cost gap is the capacity gap in a different costume.
What it does confirm is that the extra energy stays free over the long run. Across their rated lives the Ultra delivers 12,288 kWh and the Power 2000 delivers 8,192, from the same $1,299. There's no hidden column where the DJI wins that back.

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
DELTA 3 Ultra
Two nights of camping asks for 2,100Wh, and the Power 2000's label reads 2,048Wh. It's behind before you plug anything in, which is why it lands at 121% of what it can actually deliver. The Ultra covers the same weekend at 80% and still has a morning in hand. Bring 1,800W of panels and the DJI stops caring about any of this. Bring none, and it's the wrong unit for the trip.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
DELTA 3 Ultra
Eight hours of the essentials runs 1,645Wh. The Ultra spends 63% of itself on that; the Power 2000 spends 94%. Those are two different mornings, one where you're deciding what else to plug in and one where you're watching the percentage and hoping the grid wins the race. Both switch over in 10ms, so neither drops your router in the handoff. Only one has anything left when the lights come back.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A night on the machine is 320Wh, which is 12% of the Ultra and 18% of the DJI. Neither runs out and neither wakes you, since both are published at 30 dBA. It's a tie, so break it on the thing that genuinely differs: if the station gets carried to the bedroom and back, 48.5 lb beats 72.1 lb and that's the whole tiebreak.

DELTA 3 Ultra
The DELTA 3 Ultra clears the workday at 35% used, banking 1,701Wh — late work, extra calls, or a second laptop charge without arithmetic. The Power 2000 at 52% also finishes, with 831Wh of slack for the unplanned.

Tailgate Party
Game day power for the crew
DELTA 3 Ultra
Both handle game day; the DELTA 3 Ultra keeps more in reserve (26% used vs 38%). Tailgating is a light load, though, so the number you'll feel is weight: 48.5 lbs for the Power 2000 against 72.1 lbs for the DELTA 3 Ultra, from the trunk to the setup spot.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
A full day of van living asks for 4,685Wh, and neither of these is in range. The Ultra needs 179% of what it can deliver, the DJI 269%, which means recharging every single day on a schedule the road won't always cooperate with. If this is the plan, stop comparing these two and go look at systems you can build past 4,685Wh, or a house bank wired to the alternator.

Conclusion
August 2, 2026
Verdict: the DELTA 3 Ultra, on Power Score margin
Take the DELTA 3 Ultra. At an identical $1,299 it holds 3,072Wh against 2,048Wh, runs 600W more continuous output, and publishes 7,200W of surge headroom, and it clears every scenario we model except the van-life load that beats both units. The Power 2000's answers are real: 23.6 lb less to carry, and 1,800W of solar input against the Ultra's 800W. Both are conditional, though. The weight only pays if the unit actually moves, and the solar speed only pays if you own enough panel to feed it, plus DJI's separate solar adapter. If your station is going to sit in a garage waiting for an outage, or ride to one campsite and back, buy the bigger battery. If it's in and out of a hatchback every weekend with panels along, the DJI earns the 1,024Wh you're giving up.

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 3 Ultra rates 4.7/5 (80th percentile of 26 Large-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.
DELTA 3 Ultra: 72.1 lb Is a Commitment
This is the one column the Power 2000 takes without an asterisk. 23.6 lb of difference doesn't sound like much until you meet it at the moments you'd least like to: over a tailgate, down basement stairs, into a car that's already full. Decide where the Ultra is going to live before you buy it, because you won't want to relocate it on a whim.
DELTA 3 Ultra: What You Buy Is the Ceiling
The Ultra has no expansion port. 3,072Wh is what it is for the life of the unit, and if you outgrow it your upgrade path is a second unit. The Power 2000 does accept expansion batteries, which is a genuine advantage above 3,072Wh and a strange one below it, because its first added battery mostly buys back the 1,024Wh the Ultra already includes at the same price. Worth pausing on only if you know your loads are about to grow.
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.

Analyst note
The Power 2000 is cheaper to buy, but the DELTA 3 Ultra is cheaper to own. At $0.11/kWh over its lifetime vs $0.16/kWh, the DELTA 3 Ultra's higher cycle life and capacity make each dollar go further over the years. One thing to know reading the table: both carry the same 4,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.
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
Fastest-charging technology (X-Stream), deepest product ecosystem, and most active innovation cadence. At the very top of the range, the DELTA Pro Ultra platform stacks batteries and inverters into whole-home backup — a flagship path, not a line-wide feature.
Worth knowing
EcoFlow's support record is the coin-flip in this purchase. Some claims end in a prepaid label and a fast replacement; others end in long waits, or a refurbished unit against a new claim. Buying through a retailer with a generous return window is the cheap hedge, and it costs nothing to take.
DJI
Ecosystem
New entrant (2024) — five power station models to date: Power 500, Power 1000 (since superseded by the V2 but still sold), Power 1000 V2, Power 1000 Mini, Power 2000. Buying a "Power 1000" listing? Check which revision it actually ships.
Support
Leveraging DJI's established global support and repair center network from the drone business. Generally positive reputation inherited from drone operations, but limited power-station-specific track record.
Community
No dedicated power station community yet. Discussions happen within r/dji (~250K members, mostly drone users). Very small power-specific presence on Facebook and forums.
App experience
Rated 3.5/5 iOS and Android (DJI Home app ratings reflect entire DJI ecosystem including drones/cameras, not power-station-specific). Users report the on-device screen is more reliable than the app.
Unique strength
Runs quiet — 23-30dB published on most of the range (manufacturer best-case figures), at the quiet end of the category; our record carries no figure for the Power 1000 V2. Fast wall charging, quickest on the Power 1000 V2 at ~56 min — that figure is the V2's, not the whole line's. 700+ battery patents from drone R&D. SDC ports for ultra-fast DJI drone charging. Premium industrial design and build quality. LFP batteries rated for 4,000+ cycles.
Worth knowing
The 1,800W solar input is the Power 2000's headline number, and feeding it takes a part that isn't in the box. There's no built-in solar charge controller, so panels connect through DJI's separate proprietary adapter. Budget for it before you count the solar speed as a reason to buy.
Analyst note
EcoFlow has been building these for years and has the model range, the community and the field history to show for it, along with the messy support record that comes with volume. DJI has been in power stations since 2024 with essentially no long-term track record in the category, but it arrives carrying 700+ battery patents and a global repair network from the drone business. That's a real trade: a known quantity with known flaws against strong pedigree in a category it's new to.
Growth path
DELTA 3 Ultra
FIXED CAPACITYFixed at 3,072Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.
Accepts up to 800W of solar. Suitable for a 1-2 panel setup.
Generous port selection supports complex multi-device setups.
Power 2000
EXPANDABLESupports DJI expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 2,048Wh.

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
Don't read the Power 2000's expandability as a straight win here: it starts at 2,048Wh, below the DELTA 3 Ultra's 3,072Wh, so a first expansion battery largely buys back capacity the DELTA 3 Ultra already includes. It only pulls ahead if you'd grow past 3,072Wh — short of that, the DELTA 3 Ultra'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 DELTA 3 Ultra
Field data on the base DELTA 3 Ultra is thin, and most of what exists was written about its Plus sibling, which shares the chassis, the capacity and the inverter. Read it as borrowed rather than direct. What carries over is consistent: the fans never turn annoying even with the inverter at maximum outputA1A2, the casing, cable and sliding port covers all read as substantial rather than cost-engineeredA9A15, and the switchover is called seamless every time it's tested, with no dips or shutdowns when the wall feed is pulledA4A5A6.
The specifics are more useful than the praise. One reviewer ran a laptop, a desktop workstation and monitors through a full eight-hour workday and finished with 40% leftA8. Another pulled 300W to 600W from a single AC output and got a little over four and a half hoursA7. Two irritations turned up as well: the unit shuts down its 30A port first when you overload itA3, and the screen is unreadable in direct sun without cupping your hands over itA11.
“Even when you're pushing it hard, the DELTA 3 Ultra Plus runs much quieter than older EcoFlow models, like the DELTA 2 Max.”

DJI Power 2000
Reviews of the Power 2000 are uniformly warm and uniformly recent. A full wall charge lands at about 90 minutes, with some measurements closer to an hour, and a full solar charge at roughly 75 minutes on 1,800W of inputB1. It measured about 29 dB at five feet when the fan engaged and stayed among the quietest units tested even under the heaviest loadsB2. It ran everything thrown at it and handled surges consistentlyB4.
The build detail is where DJI's drone history shows: flame-retardant materials, a nano-coated BMS, 26 temperature sensors, 21 fuses, and a structure rated to hold a one-ton static loadB3. What's missing is time. Every account here is a fresh review rather than a multi-year ownership record, so none of it tells you how the unit behaves in year threeB1B4.
“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.”

“One of the quietest power stations tested — only about 29 dB at 5 feet when the fan kicked in, virtually silent, and it stayed among the quietest units even under the heaviest loads.”

Who Should Buy Which
Buy the DELTA 3 Ultra if you…
- →The station lives in a garage corner or a basement and comes out when the lights go. You'll move 72.1 lb about twice a year, and in exchange you get 3,072Wh every time you need it.
- →Your backup list has a compressor on it. The Ultra publishes 7,200W of surge against 3,600W continuous; the Power 2000's spec sheet publishes no surge figure at all, and for a well pump or a window air conditioner you want the printed number.
- →Your solar plan is one folding panel, or no panels. Without a big array the DJI's 1,800W input is a ceiling you never reach, and the comparison collapses back to which box holds more energy.
- →Two nights of car camping with a real load. The weekend model asks 2,100Wh, and only one of these clears it unassisted.
Buy the Power 2000 if you…
- →It goes in and out of a hatchback most weekends. 48.5 lb is one person and one trip, and that changes how often the thing actually gets used instead of admired.
- →You already own serious panels. At 1,800W in, reviewers measured a full solar refill in about 75 minutesB1, which turns the smaller battery into a rounding error on a sunny trip. Budget for DJI's separate solar adapter, since there's no charge controller built in.
- →You charge a laptop that pulls the full 140W over USB-C. The Ultra caps at 100W, and across a long day that shows up as a slower top-up rather than a spec-sheet footnote.
- →You know your needs are heading past 3,072Wh. The Power 2000 is the only one of the two that accepts expansion batteries, and above that line it's the only one with anywhere to go.
- →You fly DJI drones and want the SDC ports talking to gear you already own.
If neither fits
Anyone building for van life daily should close both tabs cheerfully. That load runs 4,685Wh a day, which needs 179% of what the Ultra can deliver and 269% of the DJI, so you'd be recharging on a schedule the weather gets a vote in. Look at a modular system you can build past 4,685Wh, or a proper house bank wired for alternator charging, and treat either of these as a supplement rather than the plan.
The Bottom Line
Buy the DELTA 3 Ultra. Same $1,299, 1,024Wh more energy, 600W more continuous output, and a surge figure you can read before you spend the money rather than after. Every scenario either unit can serve, it serves with more left over.
The Power 2000 wins one thing outright and it's a real thing: 23.6 lb, plus a solar input that puts its pack back in a fraction of the time. If the unit is riding in a car every weekend with panels along, that's worth the energy you're giving up. If it's waiting in a garage for the next outage, or heading to one campsite and back, carry the heavier box once and stop thinking about it.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
The DJI Power 2000 and the EcoFlow DELTA 3 Ultra cost the same. Which one should I buy?
The DELTA 3 Ultra, unless you're going to be carrying it often. At $1,299 each, the EcoFlow gives you 3,072Wh to the DJI's 2,048Wh, 600W more continuous output, and a published surge rating. The Power 2000's case is that it weighs 23.6 lb less and accepts 1,800W of solar instead of 800W, and both of those only pay off if you're genuinely moving it or you genuinely own the panels.
Can the DJI Power 2000 handle a weekend of camping?
Not on its own, by our model. A two-night camping weekend runs about 2,100Wh and the Power 2000 holds 2,048Wh on the label, so it's behind before inverter losses are counted. With panels it's a different question entirely, since reviewers measured a full solar refill in about 75 minutes at its 1,800W input. Without them, take the 3,072Wh unit.
Is the EcoFlow DELTA 3 Ultra expandable?
No. It's a sealed 3,072Wh unit with no expansion port, so what you buy is the ceiling and your upgrade path is a second unit. The Power 2000 is the one that accepts expansion batteries. Just note that it starts at 2,048Wh, so the first battery you add is largely buying back the 1,024Wh the Ultra already includes for the same $1,299.
How long does the DELTA 3 Ultra take to charge from solar?
Its solar input caps at 800W, so filling 3,072Wh from empty is just under four hours of strong sun (3,072 ÷ 800). That's most of a good solar day once conditions are less than perfect. The Power 2000 accepts 1,800W, which is why its smaller pack refills so much faster, though it needs DJI's separate solar adapter because there's no charge controller built into the station.
Which one is quieter for running a CPAP overnight?
Both are published at 30 dBA, and a CPAP night draws about 320Wh, so capacity isn't the question either: that's 12% of the Ultra and 18% of the DJI. The Power 2000 measured about 29 dB at five feet when its fan engaged, and the Ultra's fans were described as never becoming distracting even at maximum inverter output, though that testing was done on its Plus sibling. Either one will let you sleep.
