EcoFlow DELTA 3800 Gen4 vs Jackery Explorer 5000 PlusOne Extra Battery Puts It Past the Jackery. Do You Need 240 V?
Add one EcoFlow battery and the DELTA 4 (3800) holds more than the Jackery, and the station itself weighs about half as much. For a house on 120 V I'd buy the EcoFlow, unless something you own runs on 240 V.

Gunner’s take
Whole-Home Backup Tester
The DELTA 4 (3800) starts behind the Jackery and sits one battery from passing it.
It holds 3,763 Wh against the Explorer 5000 Plus's 5,040 WhA1. One DELTA 3 Max Plus extra battery adds 2,048 Wh and takes it past the JackeryA6. You can buy that battery the day you find out you need it.
The station itself weighs about half as much.
It's 67.5 lb against 134.5 lbA7. EcoFlow lists it at $2,199 and the Jackery sells for $3,149, so the EcoFlow costs less per watt-hour before anything else comes into it.
The Jackery's case is 240 V and a bigger inverter.
It runs 7,200 W, surges to 14,400 W and has two 240 V outlets. The DELTA 4 (3800) runs 3,600 W from 120 V outletsA2, and no battery you add changes that. EcoFlow ships it in late NovemberA10, and the Jackery is on sale now.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
The Jackery asks you to pay for 5,040 Wh up front and park it where it lands. The EcoFlow lets you start at 3,763 Wh, live through a winter of outages, and add the battery only if the winter says so. If it never does, you've kept the money and a box one person can carry.
DELTA 4 (3800): 3,763 Wh, with a port for up to two EcoFlow extra batteriesA6DELTA 3 Max Plus extra battery: 2,048 WhA6Explorer 5000 Plus: 5,040 Wh in one 134.5 lb box
Why it mattersIf you don't know yet whether you need 5,040 Wh, the EcoFlow lets you find out before you pay for it.
rated cycles
Spread each price over that energy and the DELTA 4 (3800) comes to $0.10 a kWh against $0.16, more than a third less. That counts when the box works for a living, on solar every day or shaving a time-of-use bill. At one cycle a day the Jackery reaches its rating in 11 years and the EcoFlow in 16.4.
DELTA 4 (3800): 6,000 rated cycles on 3,763 WhExplorer 5000 Plus: 4,000 rated cycles on 5,040 WhOver the rated life: 22,578 kWh for the DELTA 4 (3800), 20,160 kWh for the Explorer 5000 Plus
Why it mattersIf it will cycle daily off solar, the EcoFlow is both the cheaper battery to own and the longer-rated one.
continuous output
Expansion lets the DELTA 4 (3800) run longer, never harder. A 240 V well pump has nowhere to plug in, with one extra battery or two. And when the microwave, the kettle and a space heater all run at once, 3,600 W is the ceiling whatever sits behind it. The Jackery's 14,400 W surge is built for the motors that stall smaller inverters.
Explorer 5000 Plus: 7,200 W continuous, 14,400 W surge, two 240 V outletsDELTA 4 (3800): 3,600 W continuous, 7,200 W surge, 120 V outletsA2EcoFlow's extra batteries add capacity, 4 to 12 kWh in allA6
Why it mattersWrite your 240 V list first. If it isn't empty, buy the Jackery.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: Both take extra batteries. The DELTA 4 (3800) starts at 3,763 Wh and gets there in pieces.
solar input
One battery puts the DELTA 4 (3800) ahead, and you pick the day. Its battery port takes up to two extra batteries through EcoFlow's expansion adapter, either the DELTA 3 Max Plus battery or the DELTA Pro 3 battery, and EcoFlow quotes 4 to 12 kWh in allA6. The first DELTA 3 Max Plus battery is the one that passes the JackeryA6. EcoFlow also sells the station and that battery together as a kit, 6 kWh in allA10.
The Jackery grows further and starts further along. Jackery quotes 60 kWh at the topB1, far past EcoFlow's 12 kWhA6. If you're planning a whole-house bank, that settles it. If you're planning for a fridge, a furnace blower and lights, the EcoFlow's ceiling is a long way above you.
Lifetime Value
Selected because: 6,000 rated cycles against 4,000, so the smaller battery delivers more energy over its rated life.
cost / lifetime kWh
Over a battery's life, the smaller box delivers more. EcoFlow rates the DELTA 4 (3800) for 6,000 cycles and Jackery rates its unit for 4,000, so the EcoFlow moves 22,578 kWh before it reaches its rating against 20,160 kWh for the Jackery. Per kWh that's $0.10 against $0.16, more than a third cheaper to own.
It only pays if the box works. Two storms a year won't bring either battery near its rating. Run one off solar every day and the Jackery reaches its rating in 11 years, when the EcoFlow is about two-thirds of the way through its own.
What the Specs Don't Tell You
Selected because: The Jackery surges to 14,400 W against 7,200 W, and the switchover ratings are 10 ms against 20 ms.
rated cycles
A big motor is the Jackery's best argument after 240 V. It surges to 14,400 W against 7,200 W. A well pump or a shop compressor pulls hardest at switch-on, and the surge ceiling decides whether it starts. A fridge or a sump pump starts on either.
The EcoFlow is the quicker of the two on switchover, on paper. Switchover is the gap between the grid dropping and the battery picking up the load. The DELTA 4 (3800) is rated no worse than 10 msA8 and the Jackery no worse than 20 ms, which is where the fussiest PC power supplies sit. EcoFlow's FAQ also says it doesn't support HID, the USB link that tells a computer to shut itself downA8.
Portability & Form Factor
Selected because: 67.5 lb against 134.5 lb, and the EcoFlow's extra battery is a separate box.
weight
Two boxes you can lift beat one you can't. The DELTA 4 (3800) is 67.5 lb with a handle at each end, and EcoFlow sells a folding cart for itA7. I'd carry the station down basement stairs alone, and the extra battery makes its own trip.
The Jackery moves once, on its wheels. It has real wheels, a sturdy suitcase handle and side handles for a two-person liftB3, and at 134.5 lb you'll use all of them. Beside the panel, that's fine. On the way to the cabin, it isn't.

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 Explorer 5000 Plus is rated 30dB and the DELTA 3800 Gen4 40dB, but the Explorer 5000 Plus'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.

The Explorer 5000 Plus at 134.5 lbs is not a take-along — it rolls off a truck bed if it travels at all, so this scenario belongs to the DELTA 3800 Gen4 by default — and it earns it, covering the 670Wh with 2,529Wh to spare. Capacity was never the Explorer 5000 Plus's problem here; getting to a tailgate was.

Conclusion
November 4, 2026
Verdict: the EcoFlow DELTA 3800 Gen4
For a house on ordinary 120 V outlets, I'd buy the DELTA 4 (3800). It holds 3,763 Wh against 5,040 Wh, but it weighs 67.5 lb against 134.5 lb, costs less per watt-hour at $2,199 against $3,149, and is rated for 6,000 cycles against 4,000, which works out to $0.10 per lifetime kWh against $0.16. One DELTA 3 Max Plus extra battery takes it past the Jackery's 5,040 Wh whenever you decide you need itA6. Buy the Explorer 5000 Plus instead if anything runs on 240 V, if you run more than 3,600 W at once, or if the outage can't wait for EcoFlow's late-November ship dateA10.

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 Explorer 5000 Plus rates 4.8/5 (90th percentile of 22 Home Backup-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.
One Lifts Alone, One Takes Two
The DELTA 4 (3800) is 67.5 lb, a one-person lift. The Explorer 5000 Plus is 134.5 lb on wheels and stays where you roll it. For a box that lives by the panel, that difference is paid once.
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 Explorer 5000 Plus 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 DELTA 3800 Gen4 works out at 2.3 years of cover per $1,000 spent against the Explorer 5000 Plus's 1.6, but that spread is the price gap, not the terms.
The Smaller Battery Delivers More
The DELTA 4 (3800) is rated for 6,000 cycles and the Explorer 5000 Plus for 4,000. Over those ratings that's 22,578 kWh against 20,160 kWh, so the smaller battery moves more energy before it reaches its limit. It counts only if the box cycles often.

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.
Community
Largest community in the space — Reddit r/Ecoflow_community (~31K members), multiple Facebook groups, and an official community forum
App experience

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
EcoFlow and Jackery are close competitors. Both have established support channels and growing ecosystems. Compare their specific warranty terms and community size for your peace of mind.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3800 Gen4
Nobody owns a DELTA 4 (3800) yet. EcoFlow put it on sale in the US on November 4 and ships it in late NovemberA10, so this page works from EcoFlow's US store page and our arithmeticA1A6A9.
I'd want to see the station and its extra battery behave like one box. Hypothetically, I'd connect a DELTA 3 Max Plus batteryA6, run a fridge, a furnace blower and the lights for two nights, and watch whether the pair drains as one with no hiccup when the station starts drawing on the add-on.

Who Should Buy Which
Buy the DELTA 3800 Gen4 if you…
- →You'd rather start smaller and grow. 3,763 Wh now, EcoFlow's extra batteries when you need themA6.
- →Everything you'd back up runs on 120 V: a fridge, a furnace blower, the router and lights.
- →It will cycle every day. 6,000 rated cycles against 4,000.
- →One person has to move it. 67.5 lb against 134.5 lb.
Buy the Explorer 5000 Plus if you…
- →Something runs on 240 V, like a well pump or a feed into the panel.
- →Big loads run at once. 7,200 W against 3,600 W, and twice the surge.
- →You want 5,040 Wh in one box today. It's on sale now, and EcoFlow ships the DELTA 4 (3800) in late NovemberA10.
- →You own a big solar array. It takes 4,000 W against 2,000 W.
If neither fits
If the outage is a laptop and a lamp for an afternoon, close this tab. Our remote workday uses 28% of the DELTA 4 (3800). A small portable unit covers that for a fraction of either price.
The Bottom Line
If your house runs on 120 V, I'd buy the DELTA 4 (3800) and add a battery when the outages ask for one. A single DELTA 3 Max Plus battery takes it past the Jackery's 5,040 WhA6, and the station weighs about half what the Jackery does.
If anything runs on 240 V, buy the Explorer 5000 Plus. No battery you add gives the EcoFlow an outlet it doesn't have, and the Jackery ships today.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
How much is the DELTA 4 (3800) in the US, and when does it ship?
EcoFlow lists it at $2,199 on its US store. It went on sale on November 4, 2026, and EcoFlow says it ships in late November. The Explorer 5000 Plus sells for $3,149 and is on sale now.
Can the DELTA 4 (3800) hold more than the Explorer 5000 Plus?
With one extra battery, yes. A DELTA 3 Max Plus extra battery adds 2,048 Wh, which takes it past the Jackery's 5,040 Wh. The Jackery grows too, to 60 kWh by Jackery's figure.
Does the DELTA 4 (3800) have 240 V outlets?
No. Its outlets are 120 V only, and extra batteries add capacity, not outlets. The Explorer 5000 Plus has two 240 V outlets.
Which one is cheaper to own over its life?
The DELTA 4 (3800). EcoFlow rates it for 6,000 cycles and Jackery rates the Explorer 5000 Plus for 4,000, so the EcoFlow comes to $0.10 per lifetime kWh against $0.16. That only matters if the battery cycles often.
Which one is easier to move?
The DELTA 4 (3800), at 67.5 lb against 134.5 lb. The Jackery has wheels and a suitcase handle, but it is a two-person lift.
