Superseded — buy the V2
DJI has superseded the Power 1000 with the Power 1000 V2 — same $699, with 2,600W output against 2,200W. The original may still be purchasable while stock lasts, but unless it is meaningfully discounted, buy the V2.
Power 1000 V2 · $699.00Spec deltas
The EcoFlow DELTA Pro (3,600Wh) 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 Pro 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 Pro'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 Pro's real edge is surge headroom for the biggest motor starts and stacking several heavy loads at once. On stamina, the DELTA Pro keeps a fridge alive for roughly 20 hours vs the Power 1000's 6 hours. The cost? Portability. At 99 lbs, the DELTA Pro 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 Pro if your primary use is weekend camping or 8-hour blackout. Go with the Power 1000 if you primarily need it for cpap overnight. Cost to own runs close here — about $0.15/kWh for the DELTA Pro against $0.17 for the Power 1000 — so it won't be the tiebreaker. 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 Pro
With a massive 3,600W output (and 7,200W surge), the DELTA Pro can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 99 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 $0.53 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
- –Substantially more expensive (+$1,200) than the Power 1000.
- –Significantly heavier (+70.3 lbs), making it harder to move.
- –Very heavy unit that may be difficult for one person to lift.
- –Can receive complaints about fan noise under heavy load.
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
- +Costs $1,200 less
- +Lighter by 70.3 lb
Trade-offs
- –Weaker inverter (-1,400W) limits appliance compatibility.
- –Sealed capacity — the DELTA Pro can add batteries to grow past 1,024Wh; this one can't.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Power 1000
A CPAP is about 40W for eight hours, so both of these cover the night several times over — capacity isn't the question here, and the percentages are a formality. What matters is the box next to your pillow, and the only published difference is a rating: the Power 1000 is rated 23dB against the DELTA Pro's 60dB. Each is the maker's own published rating, and the makers do not measure the same way, some quoting a best case and some a figure under load, so neither number describes a 40W draw and the two are not really comparable. Treat them as a reason to look for hands-on reports before either one goes next to a bed, not as a difference you can count on hearing.

DELTA Pro
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 Pro covers it outright with 2,150Wh to spare.

Tailgate Party
Game day power for the crew
DELTA Pro
Both handle game day; the DELTA Pro keeps more in reserve (22% 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 99 lbs for the DELTA Pro, from the trunk to the setup spot.

Neither unit
Neither unit covers this scenario's 4,685Wh: the DELTA Pro comes up 1,625Wh short (about 65% 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.

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 rates 3.9/5 (33rd percentile of 16 Home Backup-class units), and Power 1000 rates 3.8/5 (31st 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.
DELTA Pro: 99 lbs Is a Commitment
At 99 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.
DELTA Pro: 60dB Published
60dB is about as loud as a normal conversation. The Power 1000 is rated 23dB — lower, but published by a different maker measuring its own way, so the two figures are not a like-for-like gap. For most people, fan noise around 45dB and up is where sleep starts to suffer.
Power 1000: Fixed Capacity
The Power 1000 is sealed at 1,024Wh — fine if that covers you, but it's the ceiling. By contrast the DELTA Pro can add expansion batteries, though the first thing it has over the Power 1000 is its own 3,600Wh base — expansion is the step after that, for the buyer who would outgrow 3,600Wh as well.
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. Worth saying because the per-dollar framing can suggest otherwise: the Power 1000 works out at 7.2 years of cover per $1,000 spent against the DELTA Pro's 2.6, but that spread is the price gap, not the terms.
Full record above — the Test Desk pick is the DELTA Pro.

Cost per delivered kWh
│ warranty ends · Reaching the cycle rating means ~80% capacity remains — degraded, not dead.
Analyst note
The Power 1000 is cheaper to buy, but the DELTA Pro is cheaper to own. At $0.15/kWh over its lifetime vs $0.17/kWh, the DELTA Pro's higher cycle life and capacity make each dollar go further over the years. One caution on the lifespan row: the Power 1000 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the DELTA Pro still delivers more over its shorter horizon (12,600 vs 4,096 kWh). Years measure wear, not usefulness.
Brand trust

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
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 Pro
EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 3,600Wh.
Accepts up to 1,600W of solar. Enough for a serious multi-panel array.
Generous port selection supports complex multi-device setups.
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
The Power 1000 is sealed at 1,024Wh, which is fine if that covers you. The DELTA Pro starts at 3,600Wh and can grow beyond it with EcoFlow expansion batteries — real headroom the Power 1000 doesn't have if your needs climb toward partial-home backup.

The Bottom Line
The full picture comes down to this. The DELTA Pro 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 Pro 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.
Is the DELTA Pro worth $1,200 more than the Power 1000?
The short answer: yes, if you'll actually use the extra capability. The DELTA Pro costs $1,200 more, but that premium buys you 2,576Wh more battery capacity (that's 15 extra hours of running a mini-fridge); 1,400W higher AC output (opening the door to more demanding appliances); 800W faster solar charging for quicker off-grid recovery. On a cost-per-watt-hour basis, you're paying $0.53/Wh vs $0.68/Wh. Factor in cycle life and the math flips: the DELTA Pro costs $0.15/kWh over its lifetime vs $0.17/kWh. The "expensive" unit is actually cheaper to own. For regular use, we'd pay the premium.
How does the 2,576Wh capacity difference actually affect daily use?
The DELTA Pro's 3,600Wh battery keeps a mini-fridge running for roughly 20 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 Pro 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 Pro'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 Pro, 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 Pro at 99 lbs? You'll want a buddy, a wagon, or wheels. For reference, 99 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 Pro 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 3.2 hours for the DELTA Pro and 1.8 hours for the Power 1000. That gap widens on cloudy days, when the DELTA Pro'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 Pro's advantage is substantial.
What if I need more capacity than the Power 1000's 1,024Wh later?
The Power 1000 is sealed at 1,024Wh, so if you expect your needs to climb, the DELTA Pro is the more future-proof pick: it starts at 3,600Wh and adds EcoFlow-compatible batteries without replacing the base unit. That said, "not expandable" isn't a flaw on its own — if 1,024Wh comfortably covers your loads, the Power 1000 is a complete unit, not a downgrade.
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 (DELTA Pro Ultra line gets 10 years). 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 Pro or the Power 1000?
We'd pay the premium for the DELTA Pro. Yes, it costs more. The capability jump is real: you're stepping into a tier that handles appliances the base model can't start. The Power 1000 is still solid if budget is the priority, but the DELTA Pro will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
