EcoFlow DELTA 3 Classic vs DJI Power 1000

DJI has replaced the Power 1000 with the Power 1000 V2, so the DELTA 3 Classic is the only current model here. Both hold the same 1,024Wh. The Classic is rated to switch to battery faster. The old DJI kept the bigger inverter and the longer cycle rating.

DJI has replaced the Power 1000 with the Power 1000 V2, and this page shows the original no price. It may still be on sale while stock lasts. The one current model here is the EcoFlow DELTA 3 Classic.

They hold the same 1,024Wh. What differs is the hardware around the battery. The DJI's inverter, the part that turns battery power into household AC, is rated higher than the Classic's, and its cells are rated for more full charges. Reviewers found it nearly silent under normal loadsB1. One ran it past its own rating for twenty minutes without a shutdownB2.

The Classic's answer is the UPS switch, which is how fast a unit takes over when wall power drops. EcoFlow rates it at 10ms or less and DJI rates the Power 1000 at 20ms or less. If this were going on my cabin desk, it would feed a router and the laptop that logs my panels, and I'd want the faster rating between them and the wall.

02

What the Numbers Reveal

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

F1

solar input

The Classic's 500W is its weakest spec, and two reviewers flagged the capA5A9. It still works the afternoon the box arrives.

DJI max solar input: 800W, through a separate DJI adapter; no charge controller built inEcoFlow max solar input: 500W, controller built inMore than one review outlet calls the Classic's 500W solar cap low for a 2026 releaseA5A9

Why it mattersSolar buyers should count the DJI adapter as part of the DJI. Wall-charging buyers can skip this, since reviews clocked the Classic under an hour and the DJI a little overA1B3.

F2

The switchover is the cleaner spec. A desktop power supply can drop out if the handoff takes too long, and the Classic's rating sits in the faster class. A CPAP sips so little that either box still has charge at sunrise.

Published noise: DJI 23dB, EcoFlow 30dB, each measured its maker's own wayUPS switchover rating: EcoFlow 10ms or less, DJI 20ms or lessCPAP Overnight scenario: 320Wh, about a third of either unit's usable charge

Why it mattersFor a desk or a NAS, which is a small home file server, the Classic's rating is the safer one. For a bedside CPAP, either covers the night.

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

Lifetime Value

Selected because: Same capacity on both sides; the DJI's cycle rating is its long-run argument, and it no longer has a price.

The lifetime table hands the DJI every cycle its rating claims, a third more lifetime energy than the Classic. With no price here, the DJI gets no cost per kilowatt-hour.

For the Classic, the table works out to $0.16 per lifetime kilowatt-hour, which is its price divided by all the energy its rated cycles would deliver.

Growth Path

Selected because: The Classic is fixed at its size, and the DJI's expansion question doesn't arise for a new buyer.

solar input

The Classic is fixed at 1,024Wh. There's no expansion battery for it, so the size on the box is the size you live with.

The DJI's side of this question doesn't help a new buyer, because the V2 has taken its place in DJI's lineup. If you might outgrow a kilowatt-hour, shop a size up, or put the V2 directly against the Classic.

Your Life, Your Pick

Selected because: Every scenario ties because the capacity is identical; the tiebreaks live off the table.

Read down the results and you get the same outcome six times. A scenario can only spend watt-hours, and these two hold the same number. Two pass, the CPAP night and the tailgate. Four fall short: the weekend, the blackout, the workday and the van.

So the tiebreaks live off the table. For a computer that has to ride through a flicker, the Classic has the faster switchover rating. For a tailgate, it is two pounds lighter to carry across the lot.

What the Specs Don't Tell You

Selected because: Four flags fire: switchover leans EcoFlow, cycle life leans DJI, warranty ties, and the Classic is fixed.

rated cycles

The switchover note leans to the Classic and the cycle-life note to the DJI. The warranty is a tie on paper, with DJI's five years depending on where the unit was bought.

A cycle gap can't matter for years, even with daily use. A slow handoff can matter the first time the power blinks with a file open.

Brand Trust

Selected because: Cross-brand pair, and DJI has already replaced its half of it.

EcoFlow has the deepest range in portable power and the largest owner community. Its app rates 4.6 out of 5 on iOS. Its support record is mixed, so a retailer with an easy return path is a useful safety net.

DJI came to power stations in 2024 with drone-grade battery engineering and a global repair network. The thin part is everything around the box. Solar runs through a DJI adapter, the SDC ports only pay off if you fly DJI drones, and DJI has already replaced this model.

Weekend Camping

Two nights off-grid with essential comfort

Neither unit

A weekend of camp power wants 2,100Wh, about twice what either box holds. Neither does this trip alone. The Classic's 500W solar input takes a panel straight away, and the DJI's needs its adapter first.

Conclusion

October 25, 2026

Verdict: the DELTA 3 Classic

Buy the DELTA 3 Classic. DJI has superseded the Power 1000 with the Power 1000 V2, so the Classic is the current model on this page, at $499. Both hold 1,024Wh, and the Classic is rated to switch to battery in 10ms or less against 20ms or less. The old DJI kept a 2,200W inverter to the Classic's 1,800W, the longer cycle rating, and a fan testers found nearly silent under normal loadsB1. None of that is a reason to hunt for leftover stock. If you want a DJI, look at the Power 1000 V2.

Test Notes & Caveats

Hidden gotchas and advantages we spotted that you won't find on the product page.

[NOTE]

The Classic Stays at 1,024Wh

The Classic doesn't take an expansion battery, so what you buy is the ceiling. Size it for what you run today.

[NOTE]

10ms or Less vs 20ms or Less

These are ratings, not measurements. EcoFlow says the Classic switches to battery in 10ms or less when the grid drops. DJI says 20ms or less for the Power 1000. Routers and most electronics ride through either. The fussiest desktop power supplies sit near the slower line.

[NOTE]

Five Years Each, With One Condition

Both units carry five-year terms. DJI advertises its full five years for units bought from DJI's own store. If you find a Power 1000 at a third-party seller, check what term comes with it before you count on the full term.

[NOTE]

Cycle Ratings: The DJI Lists More

The DJI's cells are rated for 4,000 full cycles to the Classic's 3,000. At a cycle a day that's 11 years against 8.2. At a weekend pace both ratings run for decades. The battery keeps working past the rated count, at reduced capacity.

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 Classic works out at $0.16/kWh over its rated life. If you already own the Power 1000, the hardware comparison still holds: over its rated life the DELTA 3 Classic delivers about 3,072 kWh and the Power 1000 about 4,096 kWh.

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 and chat support behind a five-year warranty. Experiences vary, so buying through a large retailer adds its own return path on top of EcoFlow's.

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

In early 2025 EcoFlow tested paywalls for some app features and paused after owner pushback. There's no parts or service program once the warranty ends, so the five-year term is what you get.

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

DJI brought drone battery engineering, more than 700 patents of it, to a box built to run quietly. The SDC ports fast-charge DJI drone packs, so it suits one owner in particular, the DJI pilot.

Worth knowing

Support comes from the drone business, which is global and mature but new to power stations. Solar needs a DJI adapter, and the 3.5 out of 5 app score covers DJI's whole product line.

All DJI power stations tested β†’

Analyst note

The category's largest ecosystem against a recent entrant. EcoFlow brings the deepest range and a well-rated app, with uneven support and one app-paywall experiment behind it. DJI brings drone-grade engineering and a quiet box inside a closed loop of DJI connectors. DJI has already moved on from its half.

Growth path

DELTA 3 Classic

FIXED CAPACITY

Fixed at 1,024Wh, with no expansion β€” so size it for your needs up front rather than planning to add capacity later.

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

Adequate ports for most setups, but heavy users may want a power strip.

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.

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.

What Owners Report

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

EcoFlow DELTA 3 Classic

Field data on the DELTA 3 Classic is an early snapshot. It launched in March 2026, and most of what exists is hands-on review testing. One review clocked a wall recharge in just under 55 minutesA1 and measured idle draw around 17WA2. It found the fans quieter than the price predictedA3. Another called the app one of the best-designed on the marketA6. A third found the Storm Guard feature, which charges the battery when a storm warning comes in, genuinely usefulA12.

The repeated complaint is solar. Two outlets called the 500W input low for a 2026 releaseA5A9. One test found the 1,800W inverter could start a small window AC but couldn't run it for long on this batteryA10. Nothing here reads like a lemon. The long-term chapters are still unwritten.

DJI Power 1000

The DJI Power 1000's reviews keep returning to one word. Quiet. Reviewers called it nearly silent under normal loads, with sound only past 1,500W, and then a soft whoosh rather than a whineB1. One test ran it at 2,400W, above its rating, for twenty minutes without a shutdownB2. A wall recharge took about 70 minutes with the fan barely audibleB3.

The field reports lean toward camping and drones. One week-long trip ran a 45W compressor fridge, phones, laptops and lights off itB4, and drone pilots like it for fast-charging DJI packsB4. DJI has replaced this model with the V2, so the long-term owner record will stay thin.

β€œWhisper-quiet operation β€” one of the quietest power stations in its class, nearly silent under normal loads; sound only becomes noticeable past 1,500W, and even then it's a soft whoosh rather than the high-pitched whirring you'd get from BLUETTI or EcoFlow.”

    β€œAC charging takes about 70 minutes from 0% to 100% (about 50 minutes to 80%), and during full-speed charging the fan barely makes a sound.”

    β€œOver a week-long camping trip it powered a 45W compressor fridge, phones, laptops, and LED lights; it's also a favorite of drone pilots for fast-charging DJI batteries while running other devices.”

Who Should Buy Which

Buy the DELTA 3 Classic if you…

  • β†’You're buying new. DJI has replaced the Power 1000, and the Classic is the current model on this page.
  • β†’Your unit's day job is a desk UPS. The Classic is rated to switch over in 10ms or less, the faster class for a PC, router or NAS.
  • β†’You want solar that works without a second order. 500W is modest, but the controller is inside.
  • β†’You're happy with 1,024Wh for good. The Classic doesn't take an expansion battery.

Buy the Power 1000 if you…

  • β†’You already own a Power 1000 and want to know what you have: a 2,200W inverter, cells rated for 4,000 cycles, and a fan reviewers call nearly silentB1.
  • β†’You fly DJI drones and found one discounted. The SDC ports fast-charge DJI packs while the AC side runs campB4.
  • β†’You want a new DJI. The Power 1000 V2 is the current model.

If neither fits

Anyone who needs a whole outage or a whole weekend from one box. The blackout scenario needs 1,645Wh and the camping weekend 2,100Wh, against 1,024Wh in each of these. Buy a bigger station instead.

The Bottom Line

DJI has moved on from the Power 1000, so this comparison has one live answer. The DELTA 3 Classic holds the same 1,024Wh, is rated to switch to battery faster, and works with a panel out of the box. The old DJI has the stronger inverter and reviewers' praise for its quietB1, and an owner has no reason to regret it.

If you're buying new, take the Classic and size it honestly, because it won't grow. If a DJI is what drew you, look at the Power 1000 V2 instead of chasing leftover stock.

Frequently Asked Questions

Answers drawn from the spec record and cited owner research.

Is the DJI Power 1000 worth buying over the EcoFlow DELTA 3 Classic?

Not new. DJI has superseded the Power 1000 with the Power 1000 V2, so the Classic is the one to buy at $499. Both store 1,024Wh. The DJI had a stronger inverter, a longer cycle rating and, by reviewers' accounts, a quieter fan. If those matter to you, compare the Classic with the Power 1000 V2.

Which is quieter, the DELTA 3 Classic or the DJI Power 1000?

DJI publishes 23dB and EcoFlow 30dB, but each maker measures its own way, so the figures are not a like-for-like test. Reviewers describe the DJI as nearly silent under typical loads, and one review found the Classic quieter than its price class suggests. We have not measured either.

Can either one carry a household through an 8-hour blackout?

No. The blackout scenario budgets 1,645Wh and each unit stores 1,024Wh, so both come up short by the same margin. Both have the surge headroom (3,600W and 4,400W) to start a fridge compressor. The Classic can't add an expansion battery, so a full night needs a larger station.

Does the DJI Power 1000 need a special adapter for solar panels?

Yes. It lists 800W of solar input but has no built-in charge controller, so panels connect through a DJI adapter sold separately. The Classic's 500W input is lower but self-contained. Plug in a panel and it charges.

Should I buy the DJI Power 1000 V2 instead?

If you want a DJI, yes. DJI's current lineup lists the Power 1000 V2 in place of the original. This page covers the original, which we no longer price. Check the V2's current specs and price against the $499 Classic before deciding.
