EcoFlow DELTA 3800 Gen4 vs Jackery HomePower 2000 Plus v2Two and a Half Times the Solar. Do You Have the Panels for It?
The DELTA 4 (3800) takes two and a half times the Jackery's solar and grows with extra batteries, at 67.5 lb. I'd buy it for a house you'll back up on solar; if the box has to travel, the Jackery is the one you'll actually carry.

Gunner’s take
Whole-Home Backup Tester
The DELTA 4 (3800) is the step up that keeps going.
Jackery's HomePower 2000 Plus v2 holds 2,048 Wh for $1,069. EcoFlow lists the DELTA 4 (3800) at $2,199 for 3,763 WhA10, and it takes two more batteriesA6, so its own battery is the floor rather than the ceiling.
The bigger difference is on the roof.
The DELTA 4 (3800) has two solar inputs, each taking 1,000 W at 11 to 60 V, for 2,000 W in allA5. The Jackery takes 800 W. That's two and a half times the solar, and in an outage that outlasts the battery, refill speed is what keeps the fridge on.
You pay for it in weight and a little per watt-hour.
The DELTA 4 (3800) is 67.5 lb against the Jackery's 41.45 lb, and EcoFlow ships it in late NovemberA10. If this box goes camping, that weight decides the page on its own.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
solar input
So in a long outage it puts back more of itself per hour of sun than the Jackery can. The Jackery's 800 W suits a 2,048 Wh battery. Hang Jackery expansion batteries off it and that same 800 W has more to fill every day.
DELTA 4 (3800): two solar inputs, 1,000 W each, 2,000 W in all at 11 to 60 VA5HomePower 2000 Plus v2: 800 W solar input3,763 Wh against 2,048 Wh
Why it mattersIf panels are part of the plan, the DELTA 4 (3800) is the box that can use them.
continuous output
A grown Jackery is a bigger tank behind 2,400 W of output and 800 W of solar. A grown DELTA 4 (3800) is a bigger tank behind 3,600 W and 2,000 W. For a box that ends up feeding house circuits, the front end you start with is the one you keep.
DELTA 4 (3800): up to two extra batteries, the DELTA Pro 3 battery or the DELTA 3 Max Plus batteryA6EcoFlow quotes 4 to 12 kWh in allA6Output: 3,600 W against 2,400 W
Why it mattersIf this is the first piece of home backup, start on the EcoFlow.
cost / lifetime kWh
Neither cost bites if the box parks by a transfer switch and stays. Both bite every trip if it goes to a campsite, where the Jackery also brings a 12 V car socket the EcoFlow doesn't haveA3.
67.5 lb against 41.45 lbBoth rated for 6,000 cycles$0.10 against $0.09 per lifetime kWh
Why it mattersIf it travels, buy the Jackery.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: Both take extra batteries. Only one grows behind a 3,600 W inverter and 2,000 W of solar.
solar input
Both grow. Only one grows into a house. The DELTA 4 (3800) takes up to two extra batteries through EcoFlow's expansion adapter, either the DELTA Pro 3 battery or the DELTA 3 Max Plus battery, and EcoFlow puts the total at 4 to 12 kWhA6. The Jackery takes Jackery's own expansion batteries.
What doesn't grow is the front end. Add batteries to either and the output and solar input stay put: 2,400 W and 800 W on the Jackery, 3,600 W and 2,000 W on the EcoFlow. On a transfer switch feeding the fridge, the furnace blower and the lights, that front end is what you live with for as long as you own it.
Your Life, Your Pick
Selected because: The 8-Hour Blackout leaves the Jackery with 96 Wh and the DELTA 4 (3800) with 1,554 Wh.
On a blackout night, the same number turns up on both sides. The Jackery finishes the 8-Hour Blackout at 94% used, with 96 Wh left. The DELTA 4 (3800) finishes with 1,554 Wh, 94% of a second night.
Camping is where the scenario wins need an asterisk. The Jackery comes up 359 Wh short of the Weekend Camping profile, and the EcoFlow covers it with 1,099 Wh spare. That's a real win, but it belongs to a 67.5 lb box someone has to get to the campsite.
Portability & Form Factor
Selected because: 67.5 lb against 41.45 lb is what everything above costs you to lift.
weight
This one rides on a cart. The DELTA 4 (3800) is 67.5 lb with a handle at each end, and EcoFlow sells a folding cart for it separatelyA7. The Jackery is 41.45 lb, a one-person trunk lift.
For a box that parks by the panel, the weight is paid once. For a box that goes to the lake every summer, it's paid every trip, and the Jackery also brings the 12 V car socket the EcoFlow left offA3.
Lifetime Value
Selected because: Both carry 6,000-cycle ratings, so the Jackery's lower price per watt-hour carries through its whole life.
cost / lifetime kWh
Over a battery life, the Jackery is a little cheaper per kWh. Both are rated for 6,000 cycles, so the difference is just price per watt-hour: $0.10 a lifetime kWh for the DELTA 4 (3800) against $0.09 for the Jackery. The extra $1,130 buys battery at a slightly higher rate, plus the solar input and the expansion the Jackery's price doesn't include.
If you'll never use those, you're paying for headroom. A box that never sees a panel or an extra battery gets the bigger tank and the bigger inverter from that $1,130, and nothing else it can use.

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 2000 Plus v2 is rated 30dB and the DELTA 3800 Gen4 40dB, but the HomePower 2000 Plus v2'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.

Conclusion
November 4, 2026
Verdict: the DELTA 3800 Gen4, on Power Score margin
I'd buy the DELTA 4 (3800) if it will live at home and grow. It holds 3,763 Wh against 2,048 Wh, takes 2,000 W of solar across two inputs against 800 W, and adds up to two extra batteries, which EcoFlow puts at 4 to 12 kWh in allA6. It costs a little more per lifetime kWh, $0.10 against $0.09, and weighs 67.5 lb against 41.45 lb. If the box travels, if you'll never add a panel or a battery, or if you need power before EcoFlow ships in late NovemberA10, the Jackery is the better buy.

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 2000 Plus v2 rates 4.3/5 (61st percentile of 29 Large-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Lifted Once, or Every Trip
The DELTA 4 (3800) weighs 67.5 lb and the Jackery 41.45 lb. Parked beside a transfer switch, that's lifted once. Taken camping, it's lifted every trip, and the Jackery is the easier one-person carry.
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 2000 Plus v2 works out at 4.7 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.

Analyst note
Both units have similar long-term ownership costs ($0.10/kWh vs $0.09/kWh). The price difference is what you see on the sticker — neither is a hidden bargain or rip-off. One thing to know reading the table: both carry the same 6,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.
Brand trust
EcoFlow
Ecosystem
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
Rated 4.6/5 iOS (~8,400 ratings) · 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 — 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.
Growth path

Analyst note
Both expand, but the DELTA 3800 Gen4's higher solar ceiling (2,000W vs 800W) gives it the stronger off-grid growth path — more panels can feed a bigger bank as it grows.
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 on November 4 and ships it in late NovemberA10, so this page runs on EcoFlow's US store page and our own arithmeticA1A5A6.
I'd want to see the 2,000 W before I counted on it. Hypothetically, I'd run a string of panels into each input on a clear winter day and watch whether the display ever reads close to the 2,000 W EcoFlow listsA5, or whether the low sun holds it well under. That reading decides how long a solar-fed outage it can ride.

Jackery HomePower 2000 Plus v2
Field data on this Jackery is thin. It launched in June 2026, and the only substantive source is launch coverage rather than a hands-on testB0. That coverage sells the weight: lighter than a Honda portable generatorB1, and about a third lighter than the model before itB2.
Nobody has reported how it behaves under load yet. Fan noise, idle drain and runtime against the rating are all missing from the recordB0, so for now the Jackery's case rests on its spec sheet, the same as the EcoFlow's.
“At 41.5 lb., the new model weighs less than a 5-gallon water cooler bottle — a Honda EU2000i portable generator (1800W rated/2200W peak, versus 2400W rated/3800W peak here) still weighs more at 47.4 lb. dry.”

“At 41.5 lb., the new model weighs less than a 5-gallon water cooler bottle — a Honda EU2000i portable generator (1800W rated/2200W peak, versus 2400W rated/3800W peak here) still weighs more at 47.4 lb. dry.”

“A ~21 lb., or 34%, weight reduction in the HomePower 2000 Plus v2 over its predecessor — that weight might still be a challenge for some people, but it is much easier to lift and move than many competing portable power sources.”

Who Should Buy Which
Buy the DELTA 3800 Gen4 if you…
- →Panels are part of the plan. It takes 2,000 W of solar across two inputs, against 800 W.
- →This is the first piece of home backup. Two extra batteries take it to as much as 12 kWh, by EcoFlow's figureA6.
- →You already own a DELTA Pro 3 or DELTA 3 Max Plus extra battery. Either one works with its expansion adapterA6.
- →It will park and stay, so 67.5 lb is a one-time lift.
Buy the HomePower 2000 Plus v2 if you…
If neither fits
If anything you'd back up runs on 240 V, close this tab. Neither unit has a 240 V outlet, so a deep well pump or an electric dryer needs a split-phase home battery instead.
The Bottom Line
If this box will live at home and grow on solar, I'd buy the DELTA 4 (3800). It takes two and a half times the solar, grows behind a 3,600 W inverter, and ends a blackout night with most of a second one still in it.
If it travels, or the outage won't wait for late November, buy the Jackery. EcoFlow ships the DELTA 4 (3800) thenA10. The Jackery is 41.45 lb and on sale now, and it covers a single night on its own.
