EcoFlow DELTA 3800 Gen4 vs Jackery HomePower 3000Same Inverter, Bigger Battery. Will You Ever Use the Room to Grow?
The DELTA 4 (3800) is the one you can build on, with twice the solar input and a port for more batteries. I'd still buy the HomePower 3000 for a 3 kWh backup, unless you'll own more than 1,000 W of panels or buy that second battery.

Gunner’s take
Whole-Home Backup Tester
The extra money buys battery and headroom, not power.
Both units run 3,600 W and surge to 7,200 WA2. The DELTA 4 (3800) holds 3,763 Wh against the HomePower 3000's 3,072 Wh, 691 Wh more, and weighs 67.5 lb against 59.5 lbA1A7.
Most of what the EcoFlow adds is for later.
It takes 2,000 W of solar across two inputs, 1,000 W eachA5, where the Jackery takes 1,000 W. It also has a port for up to two extra batteries, and EcoFlow quotes 4 to 12 kWh in allA6. The Jackery is sealed at 3,072 Wh, so its upgrade is a second box.
Today, the Jackery is the better buy per watt-hour.
It costs about a fifth less for each watt-hour of battery, and it's on sale now. EcoFlow put the DELTA 4 (3800) on sale on November 4 and ships it in late NovemberA10. If 3 kWh is the whole plan, I'd take the HomePower and spend the difference on panels.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
Both get through the eight-hour blackout. The 691 Wh extra shows up the next evening, when the EcoFlow has most of a second night left and the Jackery a bit over half of one. That's real, but it's what any bigger battery buys, and the Jackery costs about a fifth less per watt-hour.
Both: 3,600 W continuous, 7,200 W surgeDELTA 4 (3800): 3,763 Wh; HomePower 3000: 3,072 Wh8-Hour Blackout: the DELTA 4 (3800) ends with 1,554 Wh left, the HomePower 3000 with 966 Wh
Why it mattersIf your outages last one night, the Jackery covers it for less; if they run to two, the bigger battery starts to earn the gap.
That only happens if you own more than 1,000 W of panels. Feed both the same 1,000 W and the EcoFlow's second input sits empty while its bigger battery takes longer to fill. The solar case is about panels you have or will buy.
DELTA 4 (3800): two solar inputs, 1,000 W each, 11 to 60 VA5HomePower 3000: 1,000 W of solar3,763 Wh against 3,072 Wh
Why it mattersCount your panel watts first. At 1,000 W or less, the EcoFlow's solar advantage is a port you'll never plug into.
EcoFlow sells it in a kit with one DELTA 3 Max Plus extra battery, 6 kWh in allA10, which clears the 4,685 Wh day on paper even after losses. The Jackery's only route there is a second unit. Our record doesn't price the extra battery on its own, so check that number before you count on growing.
DELTA 4 (3800): up to two extra batteries, DELTA Pro 3 or DELTA 3 Max Plus; EcoFlow quotes 4 to 12 kWhA6HomePower 3000: sealed at 3,072 WhVan Life Daily needs 4,685 Wh; the DELTA 4 (3800) comes up 1,486 Wh short, the HomePower 3000 2,074 Wh
Why it mattersIf 3 kWh is a first step rather than the whole plan, the DELTA 4 (3800) is the one to start on.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: The HomePower 3000 stops at 3,072 Wh and the DELTA 4 (3800) takes extra batteries. It's the one thing the Jackery can't add later.
solar input
This is the DELTA 4's best argument. Its battery port takes up to two of EcoFlow's extra batteries, the DELTA Pro 3 or the DELTA 3 Max Plus, through EcoFlow's expansion adapter, and EcoFlow quotes 4 to 12 kWh in allA6. The solar side keeps pace, with two inputs at 1,000 W eachA5.
The Jackery is a finished product. What you buy is 3,072 Wh, and the upgrade is a second unit. That's fine if you've sized your outages. It stings if the first long one shows you hadn't, and that's the buyer the extra money is for.
Your Life, Your Pick
Selected because: The extra 691 Wh wins the camping weekend and the blackout, and it shows up as a second night's margin.
The bigger battery wins the two rows where capacity counts. A camping weekend ends at 66% used on the EcoFlow and 80% on the Jackery. The eight-hour blackout ends with 1,554 Wh against 966 Wh left, most of a second night against a bit over half of one.
Everywhere else, the 691 Wh sits idle. A CPAP, a workday and a tailgate barely dent either battery, and Van Life Daily beats both. The EcoFlow is the one that can add a battery for a day like thatA6.
Portability & Form Factor
Selected because: 67.5 lb against 59.5 lb, for 691 Wh more battery.
weight
The Jackery is the one I'd rather carry. It's described as a one-person lift, and at 16.4 inches wide it fits spaces bigger units don'tB1. Our record says 59.5 lb, though some reviews put it a little higherB0.
The DELTA 4 (3800) packs more battery per pound, and you still lift every pound. It has a handle at each end, and EcoFlow sells a folding cart separatelyA7. At nearly 8 lb more than the Jackery, I'd want the cart for basement stairs.
What the Specs Don't Tell You
Selected because: A faster switchover rating on the EcoFlow, and a wall charger worth an electrician's glance.
rated cycles
The EcoFlow switches over faster, on paper. It's rated no worse than 10 ms, the Jackery no worse than 20 ms. A router rides through either. A desktop with a fussy power supply is where 20 ms gets close to the line, though one review did measure the Jackery under 20 msB4.
I'd watch the wall circuit on the EcoFlow. It charges at up to 1,800 W, which is 15 A at 120 V, the full rating of a 15 A circuitA4. Share that circuit with a fridge and the breaker will have opinions. The app lets you set the charge rate lowerA4, and I'd turn it down a notch anywhere something else is plugged in.

LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
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 several times over — capacity isn't the question here. The only published difference is fan noise, and it can't settle this: the HomePower 3000 is rated 30dB and the DELTA 3800 Gen4 40dB, but the HomePower 3000's is its maker's best case and the DELTA 3800 Gen4's is EcoFlow's maximum under heavy charge and discharge, so at a 40W draw the real gap can only be narrower than it looks, and may even run the other way. Neither settles which box is quieter at a bedside. Buy whichever is cheaper or easier to carry.
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
Either unit
Both power your workstation all day without strain. At these utilization levels the real difference is USB-C for direct laptop charging — 140W on the DELTA 3800 Gen4 against 100W — which beats the inverter for convenience and wastes less energy.

Conclusion
November 4, 2026
Verdict: the HomePower 3000
I'd buy the HomePower 3000, unless you'll add panels or a battery. Both run 3,600 W with a 7,200 W surge, so the $800 gap buys battery and headroom, not power. Today that's 691 Wh more, which turns the eight-hour blackout's 966 Wh margin into 1,554 Wh. Later it's a second 1,000 W solar inputA5 and a port for up to two extra batteriesA6. The Jackery costs about a fifth less per watt-hour, weighs nearly 8 lb less and is on sale now, while EcoFlow ships the DELTA 4 (3800) in late NovemberA10. If you'll own more than 1,000 W of panels or buy that extra battery, the EcoFlow is the one to build on.

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 3800 Gen4 rates 4.1/5 (48th percentile of 22 Home Backup-class units), and HomePower 3000 rates 4.5/5 (71st percentile of 29 Large-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.
67.5 lb for 691 Wh More
The DELTA 4 (3800) weighs 67.5 lb against the HomePower 3000's 59.5 lb, and the extra weight is battery. It lifts by a handle at each end, and EcoFlow sells a folding cart for it separately.
The HomePower 3000 Stops at 3,072 Wh
No expansion port, so the upgrade is a second unit. The DELTA 4 (3800) takes EcoFlow's extra batteries, the one thing on this page the Jackery can't add later.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The DELTA 3800 Gen4 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The HomePower 3000 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. Both figures are maximums rather than guarantees: EcoFlow's depends on registering the unit in the EcoFlow app, which adds two years to a three-year standard term; Jackery's on registering the unit with Jackery, which is what extends the base term to the full period. Worth saying because the per-dollar framing can suggest otherwise: the HomePower 3000 works out at 3.6 years of cover per $1,000 spent against the DELTA 3800 Gen4's 2.3, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The DELTA 3800 Gen4 is rated for 6,000 cycles vs 4,000. In real life: at daily use, that's 16.4 vs 11 years. At weekend use (twice a week), it's 58 vs 38 years. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.

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.

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.
Jackery
Ecosystem
12-15+ models across Explorer (portable) and HomePower (home backup) series, plus SolarSaga panel ecosystem and innovative form factors
Support
US-based support but widely criticized. Reddit reports describe slow/dismissive responses, scripted AI agents, strict receipt requirements for warranty claims, and refurbished replacements for clearly defective units. Strongly recommended: buy from Costco or Amazon for return protection.
Community
Smallest community of the major brands — Reddit r/Jackery has ~2,000 members. YouTube presence is solid due to brand recognition.
App experience
Rated 2.3-3.3/5 iOS and Android — the weakest app experience of the major brands. Multiple confusing apps (Jackery app vs Jackery Home) and mandatory login even offline.
Unique strength
Highest brand recognition and widest retail distribution (Costco, Home Depot, Best Buy, Amazon). The "Toyota" of power stations — dependable, proven, wide availability. Innovative form factors like the Solar Gazebo and Solar Mars Bot.
Worth knowing
A couple of older models still ship NMC chemistry with a shorter rated lifespan, so check the cycle rating on the specific unit — though most of the current line has moved to LFP. Generally perceived as overpriced for the specs offered compared to newer competitors. App experience is significantly behind rivals.
Analyst note
Both brands draw support complaints, so buy either from a store with an easy return, and Jackery's reach through Costco, Home Depot, Best Buy and Amazon makes that easy. EcoFlow's app is the stronger one, and on the DELTA 4 (3800) it's where you set the charge rate.

Analyst note
The HomePower 3000 is sealed at 3,072Wh, which is fine if that covers you. The DELTA 3800 Gen4 starts at 3,763Wh and can grow beyond it with EcoFlow expansion batteries — real headroom the HomePower 3000 doesn't have if your needs climb toward partial-home backup.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3800 Gen4
Nobody in the US owns a DELTA 4 (3800) yet. EcoFlow put it on sale on November 4 and ships it in late NovemberA10, so this side of the page is EcoFlow's US store page and our own arithmeticA1A5A6.
I'd want to split two arrays across its two solar inputs. Hypothetically, a south-facing string on one input and a west-facing string on the other, up to 1,000 W eachA5, on a short November day, then a look at the battery at sundown. That's the test of whether the second input earns its keep in winter.

Jackery HomePower 3000
Reviewers treat it as a home backup that gets on with it. One kept a standard refrigerator running for nearly two days and a 55-inch TV for around 30 hours, and measured the switchover under 20 millisecondsB4. Another describes it as light enough for one person to carryB1.
The long-term record is thinner. One roundup credits Jackery with the lowest rate of reported failures and warranty claims among the major brandsB2. Each of these is a single source, so I'd read them as reviews rather than a pattern.
“Described as the world's lightest and smallest 3kWh power station thanks to an advanced cell-to-body (CTB) design — one person can carry it at around 60 lbs, and its compact 16.4-inch width fits spaces that reject rivals.”

“AC input 100–120 V, 15 A, 50/60 Hz; X-Stream charging up to 1,800 W from a US wall outlet. Our arithmetic: 1,800 W at 120 V is 15 A, the full rating of an ordinary 15 A circuit, so on a shared circuit you would set the charge rate lower in the EcoFlow app.”

Who Should Buy Which
Buy the DELTA 3800 Gen4 if you…
- →You own more than 1,000 W of panels. It takes 2,000 W across two inputsA5.
- →You'll add a battery. EcoFlow quotes 4 to 12 kWh with up to two extra batteriesA6.
- →Your outages run into a second night. It ends the eight-hour blackout with 1,554 Wh left against 966 Wh.
- →A desktop PC sits on it. Switchover is rated no worse than 10 ms against 20 ms.
Buy the HomePower 3000 if you…
- →3 kWh is the whole plan. At $1,399 it costs about a fifth less per watt-hour.
- →You'll carry it. 59.5 lb against 67.5 lb.
- →It lives in an RV or a van. Our record gives it a 12 V car socket and an RV 30 A outlet, and the DELTA 4 (3800) has no car socketA3.
- →You need it before late November. It's on sale now, and EcoFlow ships the DELTA 4 (3800) thenA10.
If neither fits
If you want the whole house backed up, skip both. Even the DELTA 4 (3800) runs 3,600 W and tops out at 12 kWh by EcoFlow's figureA6, and neither has a 240 V outlet. Look at a whole-home system like EcoFlow's TITAN line.
The Bottom Line
For a 3 kWh backup you'll set and forget, buy the HomePower 3000. Same inverter, less per watt-hour, lighter, and on sale now.
If this is the first piece of a bigger system, buy the DELTA 4 (3800). Twice the solar and a port for more batteries are the two things the Jackery can't add later.
