EcoFlow DELTA 3 vs DJI Power 1000

DJI has replaced the Power 1000 with the V2, which leaves the DELTA 3 as the one to buy new. Both hold 1,024Wh. The DELTA 3 has six AC outlets to two, a faster switchover rating, and room for an EcoFlow expansion battery.

This was a close fight until DJI replaced the Power 1000 with the Power 1000 V2. This page shows the original no price, so the EcoFlow DELTA 3 is the one to order new. The comparison still matters if you own a Power 1000 or have spotted one on a clearance shelf.

The batteries are the same size. Each holds 1,024Wh of LFP, a lithium chemistry built for thousands of charges. What separates them is the box. The DELTA 3 has six AC outlets and a car socket. The DJI has two outlets and no car socket. If I were wiring a cabin corner for a router, a lamp, a small fridge and a phone charger, I'd run out of DJI sockets before I ran out of battery.

The DJI's advantages were real. Its inverter surges to 4,400W against the DELTA 3's 3,600W, which helps a stubborn compressor start. It takes more solar on paper, through a separate DJI adapter. Reviewers call it nearly silent under normal loadsB1.

02

What the Numbers Reveal

Each conclusion stated first β€” the numbers behind it on one line, the full analysis below.

F1

So the choice sits in the hardware around the cells. The DELTA 3's switchover rating is the faster class, the one a desktop power supply prefers. A review of a sibling DELTA 3 with the same rating saw routers and a CPAP ride through a cutA2.

Both units hold 1,024Wh and list 4,000 cyclesThe DELTA 3 costs $629; the Power 1000 has been superseded by the Power 1000 V2The DELTA 3 is rated to switch over in 10ms or less, the DJI in 20ms or less

Why it mattersFor a desk or a home office, the DELTA 3 is the box I'd want between the wall and the computer.

F2

continuous output

Surge is the short burst an inverter gives when a motor starts, and the DJI had more of it. Its solar figure needed a DJI adapter before any panel could charge it. The DELTA 3 takes a panel straight in.

DJI: 2,200W output, 4,400W surge. DELTA 3: 1,800W output, 3,600W surgeDJI solar: 800W through a separate DJI adapter; DELTA 3: 500W with the controller built inAC outlets: DELTA 3 six, DJI two

Why it mattersIf you own a Power 1000 and a hard-starting fridge, you have the stronger starter. If you're buying, check your hardest-starting appliance against the DELTA 3's surge rating.

The specific dimensions that decide these two units β€” everything else is a tie.

What the Specs Don't Tell You

Selected because: Switchover leans EcoFlow and the warranty ties.

Switchover leans to the DELTA 3, whose rating sits in the faster class for desktop power supplies. Warranty is a tie at five years, with DJI's full term tied to buying from DJI's own store.

Lifetime Value

Selected because: Same lifetime energy on paper, and only the DELTA 3 still has a price.

The same capacity and the same listed cycles give the same lifetime energy, 4,096 kWh from each. For the DELTA 3 that works out to $0.15 per lifetime kilowatt-hour. The DJI gets no figure here because it no longer has a price.

If you find a Power 1000 at a deep discount, divide the price by 4,096 and set it beside the DELTA 3's figure. Then check whether the seller's warranty matches the five years DJI offers through its own store.

Growth Path

Selected because: The DELTA 3 takes EcoFlow expansion batteries; the DJI question doesn't arise for a new buyer.

solar input

The DELTA 3 takes EcoFlow expansion batteries, so its 1,024Wh isn't the ceiling. If a trip or an outage outgrows it, an add-on battery is an accessory purchase rather than a second station.

Brand Trust

Selected because: EcoFlow's open solar input and range against DJI's adapter and a model already replaced.

EcoFlow's app rates 4.6 out of 5 on iOS. Its support record is mixed, so a retailer with an easy return window is worth the small effort.

DJI brought drone-grade engineering to power stations in 2024, and the Power 1000's quiet and its output drew steady praiseB1B2.

Conclusion

October 25, 2026

Verdict: the DELTA 3

Buy the EcoFlow DELTA 3. DJI has superseded the Power 1000 with the Power 1000 V2, which leaves the DELTA 3, at $629, as the one to buy new. Both hold 1,024Wh. The DELTA 3 has six AC outlets to the DJI's two and a faster switchover rating, and it takes EcoFlow expansion batteries. The old DJI has the stronger inverter and a fan reviewers call nearly silentB1. If you want a DJI, look at the Power 1000 V2.

Today the DELTA 3 is $599, $30 under its typical $629. The verdict weighs typical prices, not today's. Prices checked 28 days ago.

Owner claims

Statements about owner experience are cited to published reviews β€” see Sources & Research Notes below.

Runtime model

Runtime = (rated capacity Γ— 0.85 inverter efficiency) Γ· 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.

Class ranking (the star rating)

Each unit's star score is a category ranking, not customer reviews β€” 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 5β˜…. Here, DELTA 3 rates 4.5/5 (73rd percentile of 27 Everyday-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.

[NOTE]

10ms or Less vs 20ms or Less

These are the makers' ratings. Routers and most electronics ride through either. The fussiest desktop power supplies sit near the slower line, so a PC with unsaved work belongs on the faster rating.

A Tie, If It Came From DJI

Both carry five years. DJI advertises its full term for units bought from DJI's own store. A Power 1000 from a clearance listing may come with less, so ask before you pay.

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 works out at $0.15/kWh over its rated life. If you already own the Power 1000, the hardware comparison still holds: each delivers about 4,096 kWh over its rated life. 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 β€” the wear horizon is identical and decides nothing here.

Brand trust

EcoFlow

Ecosystem

Largest in portable power β€” 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 β€” 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 β€” Reddit r/Ecoflow_community (~31K members), multiple Facebook groups, and an official community forum

App experience

Rated 4.6/5 iOS (~8,400 ratings) Β· 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 β€” 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.

All EcoFlow power stations tested β†’

DJI

Ecosystem

New entrant (2024) β€” 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 β€” 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 β€” 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 β€” 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 β€” check the specific model.

All DJI power stations tested β†’

Analyst note

EcoFlow brings the deepest range in portable power, a solar input that works with standard panels, and an expansion path for this unit. DJI brought drone-grade build and a quiet box, with a DJI-only solar adapter and SDC ports aimed at its own drone owners. Most testing covers the DELTA 3's siblings, so its own record is thin.

Growth path

DELTA 3

EXPANDABLE

Supports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit β€” useful if your needs may climb past 1,024Wh.

Accepts up to 500W of solar. Suitable for a 1-2 panel setup.

Generous port selection supports complex multi-device setups.

Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.

Power 1000

EXPANDABLE

Supports DJI expansion batteries, so you can add capacity later without replacing the base unit β€” useful if your needs may climb past 1,024Wh.

DELTA 3Power 1000

Analyst note

Growth only counts if you can still buy in, and DJI has replaced the Power 1000 with the V2. That leaves the DELTA 3. It starts at 1,024Wh and takes EcoFlow expansion batteries, so the ceiling moves if your needs do.

What Owners Report

Patterns from published owner reports and long-term reviews β€” every claim cited to its source below.

EcoFlow DELTA 3

Field data on the standard DELTA 3 is thin. Most published testing covers its Plus and Max siblingsA0. Under 200W the fans often stay off, and at moderate load they're barely audible from three feet awayA1.

The UPS report comes from a review of a sibling with the same 10ms rating, so it's a hint rather than a test of this unit. It describes a cut that routers, fridges and CPAP machines rode throughA2.

β€œAt low loads (under 200W) the fans often stay completely off, making the Delta 3 effectively silent; under moderate load (500–800W) the fans are barely audible from three feet away.”

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.

Buy the Power 1000 if you…

  • β†’You already own a Power 1000. Its 4,400W surge and quiet fanB1 are good reasons to keep it.
  • β†’You fly DJI drones and found one discounted. The SDC ports fast-charge DJI packsB4.
  • β†’You want a new DJI. Look at the Power 1000 V2, the model DJI sells now.

If neither fits

Both hold 1,024Wh, so neither covers a full 8-hour blackout alone. The DELTA 3 can add a battery toward it. For whole-outage runtime in one box, step up a size class.

The Bottom Line

The DELTA 3 is the one to buy. DJI has moved on from the Power 1000. The DELTA 3 has more sockets and a faster switchover rating, and it can take an expansion battery.

The DJI was a fine unit with a stronger inverter and a reputation for quietB1. If you own one, keep it. If you want a new DJI, look at the Power 1000 V2 rather than leftover stock.
