Spec deltas
The EcoFlow DELTA 3 Ultra Plus (3,072Wh) and DJI Power 1000 (1,024Wh) sit in different weight classes. The real question: do your power needs justify the larger unit, or would you be overpaying for capacity that sits unused? The DELTA 3 Ultra Plus has a slight edge, but the margin is close enough that your use case should break the tie.
What the spec gap means in practice: the DELTA 3 Ultra Plus's 3,600W inverter has the headroom for a window AC, a full-size fridge, and power tools. The Power 1000's 2,200W inverter still runs most single appliances; the DELTA 3 Ultra Plus's real edge is surge headroom for the biggest motor starts and stacking several heavy loads at once. On stamina, the DELTA 3 Ultra Plus keeps a fridge alive for roughly 17 hours vs the Power 1000's 6 hours. The cost? Portability. At 74.3 lbs, the DELTA 3 Ultra Plus is heavy enough to make you think twice about moving it. The Power 1000 at 28.7 lbs is something one person can actually carry.
Pick the DELTA 3 Ultra Plus if your primary use is weekend camping or 8-hour blackout. Go with the Power 1000 if you want the option to add expansion batteries later. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.
Bench Notes
What each unit does well, where it falls short, and the trade-offs that matter.
EcoFlow DELTA 3 Ultra Plus
With a massive 3,600W output (and 7,200W surge), the DELTA 3 Ultra Plus can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 74.3 lbs, this is not a unit you want to carry far. It's best suited as a stationary backup or RV companion. A standout feature is the value proposition: at roughly $0.52 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Faster solar charging
Trade-offs
- –Significantly heavier (+45.6 lbs), making it harder to move.
DJI Power 1000
The 2,200W inverter handles most daily devices like laptops, blenders, and TVs, but will struggle with heating elements that require over 1500W.
Strengths
- +Lighter by 45.6 lb
Trade-offs
- –Weaker inverter (-1,400W) limits appliance compatibility.

Weekend Camping
Two nights off-grid with essential comfort
DELTA 3 Ultra Plus
The Power 1000 doesn't finish — 870Wh usable against the 2,100Wh this needs leaves it 1,230Wh short, about 41% of the scenario covered. The DELTA 3 Ultra Plus covers it with 511Wh to spare.

DELTA 3 Ultra Plus
The Power 1000 doesn't finish — 870Wh usable against the 1,645Wh this needs leaves it 775Wh short, about 53% of the scenario covered. The DELTA 3 Ultra Plus covers it with 966Wh to spare.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP is about 40W for eight hours, so both of these cover the night at least twice over — capacity isn't the question here. The only published difference is fan noise, and it can't settle this: the Power 1000 is rated 23dB and the DELTA 3 Ultra Plus 30dB, but they are two makers' figures, each measured its own way. Neither settles which box is quieter at a bedside. Only the DELTA 3 Ultra Plus is still sold, so a new purchase here is just the DELTA 3 Ultra Plus; the Power 1000 is a used-market question.
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 3 Ultra Plus
The Power 1000 comes up just short — it needs 910Wh and has 870Wh usable, a 40Wh gap (its nameplate 1,024Wh actually clears this — the flat 15% conversion allowance is what tips it under). Trim that much — one small appliance's worth across the day — and it finishes. The DELTA 3 Ultra Plus covers it outright with 1,701Wh to spare.

Tailgate Party
Game day power for the crew
DELTA 3 Ultra Plus
Both handle game day; the DELTA 3 Ultra Plus keeps more in reserve (26% used vs 77%). Tailgating is a light load, though, so the number you'll feel is weight: 28.7 lbs for the Power 1000 against 74.3 lbs for the DELTA 3 Ultra Plus, from the trunk to the setup spot.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit covers this scenario's 4,685Wh: the DELTA 3 Ultra Plus comes up 2,074Wh short (about 56% covered), the Power 1000 3,815Wh (19%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

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 Plus rates 4.9/5 (96th percentile of 27 Large-class units), and Power 1000 rates 4.3/5 (58th percentile of 27 Everyday-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
DELTA 3 Ultra Plus: 74.3 lbs Is a Commitment
At 74.3 lbs, this is manageable but not fun to move. That's heavier than a large checked suitcase. How much it costs you depends on whether it rolls — wheels and a telescoping handle change the job completely at this weight, and our spec record doesn't track them, so look at the product photos before you plan on carrying it from the car.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The DELTA 3 Ultra Plus is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The Power 1000 is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The Power 1000'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 1000 is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the DELTA 3 Ultra Plus works out at $0.13/kWh over its rated life. If you already own the Power 1000, the hardware comparison still holds: over its rated life the DELTA 3 Ultra Plus delivers about 12,288 kWh and the Power 1000 about 4,096 kWh. 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

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 top of the range sit two whole-home paths: the TITAN line, one 5 kWh unit that grows to 30 kWh, and the DELTA Pro Ultra platform, which stacks batteries and inverters further — flagship paths, not line-wide features.
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
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
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 and DJI are close competitors. Both have established support channels and growing ecosystems. Compare their specific warranty terms and community size for your peace of mind.
Growth path
DELTA 3 Ultra Plus
EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 3,072Wh.
Accepts up to 1,600W of solar. Enough for a serious multi-panel array.
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
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
Growth only counts if you can still buy in, and the Power 1000 is no longer sold (DJI points owners to the Power 1000 V2). That leaves the DELTA 3 Ultra Plus: it starts at 3,072Wh and takes EcoFlow expansion batteries, so the ceiling moves if your needs do. The Power 1000's expandability still matters if you already own one, but it isn't a reason to pick it over the DELTA 3 Ultra Plus.
The Bottom Line
The full picture comes down to this. The DELTA 3 Ultra Plus edges ahead on our overall analysis, but the margin is narrow enough that your specific use case should drive the decision. Review the scenario verdicts above — if the Power 1000 wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the DELTA 3 Ultra Plus nor the Power 1000 feels like the right fit, your power needs probably sit outside what these two target. Use our comparison tool above to explore alternatives that better match your specific wattage and runtime requirements. Prices on portable power stations fluctuate frequently. Both EcoFlow and DJI discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
How does the 2,048Wh capacity difference actually affect daily use?
The DELTA 3 Ultra Plus's 3,072Wh battery keeps a mini-fridge running for roughly 17 hours vs the Power 1000's 6 hours. Where it really matters: during an 8-hour blackout running your fridge, router, lights, AND charging your phone simultaneously (about 1,645Wh total), the DELTA 3 Ultra Plus handles it while the Power 1000 runs dry. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The DELTA 3 Ultra Plus's extra capacity provides a critical cold-weather buffer. For occasional phone and laptop charging, both are overkill. This gap only matters for sustained, multi-appliance use.
Can I actually carry the DELTA 3 Ultra Plus, or is the Power 1000 the only portable option?
At 28.7 lbs, the Power 1000 is manageable for one person over short distances: parking lot to campsite, trunk to tailgate. The DELTA 3 Ultra Plus at 74.3 lbs? You'll want a buddy, a wagon, or wheels. For reference, 74.3 lbs is about the weight of a bag of concrete. If your use case involves any carrying, the Power 1000 wins decisively.
How fast can each unit recharge from solar panels in real conditions?
On paper, the DELTA 3 Ultra Plus accepts 1,600W vs the Power 1000's 800W of solar input. What the spec sheet won't tell you: solar panels typically deliver only 60-80% of their rated output due to panel angle, cloud cover, and temperature. In realistic conditions, expect full recharge in about 2.7 hours for the DELTA 3 Ultra Plus and 1.8 hours for the Power 1000. That gap widens on cloudy days, when the DELTA 3 Ultra Plus's higher input ceiling captures more of whatever sunlight is available. One more thing: summer gives you ~7 productive solar hours per day. Winter drops to ~4. If solar is your primary recharge method, the DELTA 3 Ultra Plus's advantage is substantial.
Is EcoFlow or DJI more reliable for long-term ownership?
Both brands have strengths and trade-offs. EcoFlow: Mixed. 2-5 years depending on model. Some users report smooth claims; others report runarounds. Register your product to extend coverage. DJI: 3-5 years depending on model. DJI has a reasonable track record from drone products. Too early for comprehensive power station warranty data. One piece of advice from the power station community: regardless of brand, buy from Costco or Amazon. Their return policies provide a safety net that manufacturer warranties alone can't match, especially for a product you'll rely on in emergencies. Both brands use LFP (lithium iron phosphate) batteries in their current lineup, the most proven chemistry for longevity and safety.
Bottom line: should I buy the DELTA 3 Ultra Plus or the Power 1000?
We'd buy the DELTA 3 Ultra Plus. The Power 1000 is no longer sold, so there is no price to weigh it against; the comparison on this page still helps if you own one.
