EcoFlow DELTA 3000 Gen4 vs BLUETTI Elite 320Twice the Inverter, a Smaller Battery. Who Needs 3,600 W?

The Elite 320 holds more battery for less money, and the EcoFlow answers with twice the inverter and 17.7 lb less to carry. I'd buy the Elite unless the things you run at once pass 1,800 W or the box lives at the bottom of a staircase.

Gunner’s take

Whole-Home Backup Tester

The BLUETTI holds more and costs less.

The Elite 320 has a 3,200 Wh battery and sells for $1,100. EcoFlow's DELTA 4 (3000) holds 3,072 WhA1 and lists at $1,699. That's 128 Wh less battery for $599 more.

What the extra money buys is an inverter.

The DELTA 4 (3000) runs 3,600 W at 120 V and surges to 7,200 WA2. The Elite 320 runs 1,800 W and surges to 3,600 W. The battery decides how long the lights stay on. The inverter decides how much runs at the same moment.

It also buys 17.7 lb and a longer cycle rating.

The DELTA 4 (3000) weighs 57.3 lb against about 75 lb, and EcoFlow rates it for 6,000 cycles against the Elite's 3,000A9. EcoFlow says it ships in early DecemberA10. For a house that runs a fridge, a router and the lights, I'd still take the Elite.

02

What the Numbers Reveal

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

F1

continuous output

A fridge, a router, lights and a furnace blower run together inside 1,800 W, and the Elite's 3,600 W surge starts the fridge compressor. The limit bites when two big loads overlap, like a microwave and a kettle at breakfast. The DELTA 4 has the inverter to load its 30 A twist-lock to the rating, since 3,600 W at 120 V is 30 AA3.

Elite 320: 3,200 Wh, 1,800 W continuous, 3,600 W surgeDELTA 4 (3000): 3,072 Wh, 3,600 W continuous at 120 V, 7,200 W surgeA2DELTA 4 (3000): one 30 A twist-lock among its five outletsA3

Why it mattersAdd up what runs at the same moment in your outage. If it stays under 1,800 W, the bigger inverter is headroom you paid for and never use.

F2

rated cycles

By the page's lifetime math the DELTA 4 (3000) works out at $0.09 per lifetime kWh against $0.11 for the Elite. That math assumes you cycle it. At one outage night a month, 3,000 cycles takes a couple of centuries.

DELTA 4 (3000): rated for 6,000 cyclesA9Elite 320: rated for 3,000 cycles, 8.2 years at one cycle a dayThe Elite 320 costs far less per watt-hour of battery

Why it mattersIf it will cycle daily off solar, count the cycles. If it waits in a closet for storms, don't.

F3

weight

Across a kitchen or a garage slab, wheels make the Elite's extra 17.7 lb disappear. On basement stairs or into a trunk, wheels do nothing and the weight is all that counts. The Elite also keeps a car-style 12 V outlet for a cooler or a tire pump.

DELTA 4 (3000): 57.3 lb, a handle at each end, folding cart sold separatelyA7Elite 320: about 75 lb on oversized wheels with a telescoping handleB2Elite 320: one 12 V car outlet; DELTA 4 (3000): noneA3

Why it mattersOne floor, the Elite. Stairs, the DELTA 4 (3000).

The specific dimensions that decide these two units — everything else is a tie.

What the Specs Don't Tell You

Selected because: The inverters are 3,600 W against 1,800 W, and the Elite's heater mode does nothing for motors.

rated cycles

1,800 W is plenty until two things start at once. The Elite 320 surges to 3,600 W, twice its running rating, which covers a fridge compressor's kick. What it won't do is run a microwave and a kettle together. The DELTA 4 (3000) has twice the continuous output, and that's most of what the extra money buys.

Power Lifting makes a kettle slower. It runs resistive loads up to 2,700 W by feeding them less than they ask forB1. A pump or a saw gets the plain 3,600 W surge. EcoFlow has its own version, X-Boost, and its US store page sends you to the manual for the figureA2.

Portability & Form Factor

Selected because: 57.3 lb on two handles against about 75 lb on wheels.

weight

I'd rather roll 75 lb than carry 57.3. On a flat floor, anyway. Reviews describe the Elite 320 on oversized wheels with a telescoping handleB2, so it goes from the closet to the fridge like carry-on luggage.

Stairs reverse it. The DELTA 4 (3000) has a handle at each end and no wheels, and EcoFlow sells a folding cart separatelyA7. Down to a basement, where the electrical panel usually lives, I'd take the lighter one every time. Wheels don't help on stairs.

Lifetime Value

Selected because: 6,000 cycles against 3,000, which counts only if the box cycles often.

cost / lifetime kWh

On paper, the DELTA 4 (3000) is the cheaper one to own. EcoFlow rates it for 6,000 cyclesA9, twice the Elite's 3,000, and that's enough to beat the Elite per lifetime kWh despite the higher price. Even so, the Elite lasts 8.2 years at one full cycle a day.

A storm box never collects on that. Backup that runs a few nights a year won't come near 3,000 cycles in the years you'll own it. The lifetime math pays off only with daily cycling, off solar at a cabin or in a van.

Your Life, Your Pick

Selected because: Every scenario but Van Life Daily goes to both, so the battery doesn't split them.

Capacity doesn't decide this pair. The eight-hour blackout needs 1,645 Wh, and the two finish with 966 Wh and 1,075 Wh left. A CPAP night, a remote workday and a tailgate leave most of either battery untouched.

Van Life Daily beats both, and neither one grows. It needs 4,685 Wh. The DELTA 4 (3000) has no extra-battery portA6, and the Elite 320 is sealed too. If your days look like that, start with an expandable unit.

Brand Trust

Selected because: Both warranties reach 5 years only with conditions, and the two support setups differ.

Both warranties reach 5 years, each with a condition. EcoFlow gives 3 years plus 2 more when you register the DELTA 4 (3000) in its appA9. BLUETTI's 5 depends on buying direct or registering, since a reseller purchase carries a shorter term.

Support is where they differ. EcoFlow runs a US phone line alongside email and chat. BLUETTI works mostly by email across China time zones, so I'd buy the Elite direct from BLUETTI if I could.

Weekend Camping

Two nights off-grid with essential comfort

Either unit

Both cover the 2,100 Wh weekend with room left. The DELTA 4 (3000) is the one you'd carry to the site. The Elite 320 is the one you'd roll.

8-Hour Blackout

Keep the essentials running through a night without power

Either unit

Both finish the 1,645 Wh night, with 966 Wh and 1,075 Wh left. The Elite's slightly bigger battery is the only gap, and it's a small one.

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. What would separate them is fan noise, but Elite 320 doesn't publish a figure, so there's nothing to hold it to. Buy on price, weight, and whether you can live with a fan you haven't heard.

Tailgate Party

Game day power for the crew

Either unit

Both handle game day easily. Since capacity isn't the deciding factor, weight is: at 57.3 lbs the DELTA 3000 Gen4 is the one you'll be glad you brought. Fan noise under load is worth a listen too — it's audible in the lulls between songs.

Conclusion

November 4, 2026

Verdict: the Elite 320

Buy the Elite 320, unless what you run at once passes 1,800 W. It holds 3,200 Wh against 3,072 WhA1, rolls on wheelsB2, costs far less per watt-hour and is on sale now. The DELTA 4 (3000) answers with 3,600 W and a 7,200 W surgeA2, 17.7 lb less weight and twice the cycle rating. Those are real advantages, but a fridge, a furnace blower, a router and the lights never ask for them.

Today the Elite 320 is $936.25, $163.74 under its typical $1,099.99. The verdict weighs typical prices, not today's. Prices checked 31 days ago.

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 3000 Gen4 rates 4.8/5 (86th percentile of 29 Large-class units), and Elite 320 rates 4.1/5 (46th percentile of 29 Large-class units).

Test Notes & Caveats

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

[NOTE]

Heavier, but It Rolls

The Elite 320 is about 75 lb against the DELTA 4 (3000)'s 57.3 lb. It rolls on wheels with a telescoping handle, so a flat floor is easy. Stairs and car trunks are where the extra 17.7 lb shows up.

[NOTE]

Elite 320: Power Lifting to 2,700W

The Elite 320 has BLUETTI's Power Lifting mode, which runs a resistive appliance rated up to 2,700W from its 1,800W inverter. It does that by delivering less power than the appliance asks for, not more than the inverter has: the heater still works, it just heats more slowly. Two things follow. BLUETTI scopes the mode to purely resistive loads — a heater, a kettle, an incandescent lamp — so it does nothing for a fridge compressor, a pump or a power tool; for motor loads the figure to read is the Elite 320's separate 3,600W surge peak, not this one. And it is not a reason to size down, because running a load that big from 3,200Wh is a short session either way. Genuinely useful if a heater or a kettle is why you're buying; beside the point otherwise. EcoFlow's X-Boost works the same way, running a resistive load past the inverter's rating at reduced power, but our record for the DELTA 3000 Gen4 carries no X-Boost figure, so check EcoFlow's spec sheet before comparing the two ceilings.

[NOTE]

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; BLUETTI's on buying direct from BLUETTI or registering the unit, since reseller purchases carry a shorter term. Worth saying because the per-dollar framing can suggest otherwise: the Elite 320 works out at 4.5 years of cover per $1,000 spent against the DELTA 3000 Gen4's 2.9, but that spread is the price gap, not the terms.

[NOTE]

Battery Lifespan in Real Years

The DELTA 3000 Gen4 is rated for 6,000 cycles vs 3,000. In real life: at daily use, that's 16.4 vs 8.2 years. At weekend use (twice a week), it's 58 vs 29 years. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.

[NOTE]

Elite 320: Noise Level Not Disclosed

The DELTA 3000 Gen4 publishes its noise level (40dB); the Elite 320 doesn't publish one. That isn't evidence the Elite 320 is louder — it means there's no figure to hold it to, and no way to compare the two on this without hearing them. If you're buying for a bedroom, a CPAP, or an apartment, treat the DELTA 3000 Gen4's 40dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the Elite 320 before deciding.

Full record above — the Test Desk pick is the Elite 320.

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.

BLUETTI

Ecosystem

One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.

Support

The most inconsistent support in the space. Heavily email-based with China timezone delays. Some users get smooth, efficient service; others report weeks of troubleshooting runarounds, being offered discounts on new units instead of repairs, and confusing third-party purchase claim processes. Buying direct from Bluetti's website tends to produce better support outcomes.

Community

Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.

App experience

Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.

Unique strength

Among the best capacity-to-price ratios available — several Elite and Apex units are the lowest $/Wh in the catalog. Widest product diversity including industry-firsts like sodium-ion cold-weather units and dual solar+alternator vehicle hubs. LFP across the rest of the range, though rated cycle life spans 2,500 (EB3A) to 6,000, and it varies WITHIN the Elite range rather than tracking it — the Elite 300 and Elite 200 V2 are rated 6,000 while the Elite 30 V2, Elite 10 Mini, Elite 320 and Elite 400 are rated 3,000+ and the Elite 100 V2 4,000+, so check the specific model. Dual-voltage (120V/240V) in flagships.

Worth knowing

Customer support inconsistency is the #1 risk factor. Older/discontinued units may become unrepairable — no spare parts policy for some models. Some reports of erratic communication from support agents.

Analyst note

EcoFlow positions itself as a mid-to-premium brand with stronger support infrastructure, while BLUETTI competes on value. The question is whether the EcoFlow ecosystem and support premium is worth it for your use case.

Growth path

DELTA 3000 Gen4

FIXED CAPACITY

Fixed at 3,072Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.

Accepts up to 1,000W of solar. Enough for a serious multi-panel array.

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

Elite 320

FIXED CAPACITY

Fixed at 3,200Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.

Accepts up to 1,000W of solar. Enough for a serious multi-panel array.

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

DELTA 3000 Gen4Elite 320

Analyst note

Neither expands, and that's no knock on either — each is a complete unit at a fixed size. Buy the capacity that covers your needs now (the Elite 320 gives you the larger ceiling); you can't add to either later.

What Owners Report

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

EcoFlow DELTA 3000 Gen4

Nobody owns a DELTA 4 (3000) yet. EcoFlow put it on sale in the US on November 4 and says it ships in early DecemberA10, so everything here is EcoFlow's store page and FAQ, plus our own arithmeticA1A4.

I'd want to run the full 1,800 W wall charge on a real garage circuit. That's 15 A at 120 V, the whole rating of a 15 A circuitA4. I'd plug it in beside a chest freezer on the same breaker, see which one complains first, and then turn the charge rate down in the app.

“Capacity 3,072 Wh, LFP (LiFePO4) cells. EcoFlow sells it as the DELTA 3000 Gen4; buyers and the press call the pair the DELTA 4.”

BLUETTI Elite 320

Our Elite 320 file is launch coverage, not owners. Reviews describe a suitcase-style home-backup unit on oversized wheels with a telescoping handle, introduced at CES 2026B1B2.

The fridge claims don't compare. Coverage repeats a claim of over 66 hours of refrigeration from the Elite 320B3, and EcoFlow claims up to 58 hours for the DELTA 4 (3000)A12. Neither names the fridge, so I'd treat both as a rough promise rather than a contest.

“A 3,200Wh LiFePO4 battery delivering 1,800W continuous (2,700W Power Lifting, 3,600W peak), with 10ms UPS protection — a suitcase-style rolling home-backup station introduced at CES 2026.”

Who Should Buy Which

Buy the DELTA 3000 Gen4 if you…

  • →Two big loads share your outage, like a microwave beside a kettle. 3,600 W against 1,800 W.
  • →It goes up and down stairs. 57.3 lb on two handles, 17.7 lb less than the Elite.
  • →It will cycle every day off solar. 6,000 cycles against 3,000.
  • →You want a fast refill from the wall. Up to 1,800 W by EcoFlow's figureA4.

This is you — check the DELTA 3000 Gen4 price

Buy the Elite 320 if you…

  • →Everything you'd run at once fits under 1,800 W: a fridge, a router, lights and a CPAP.
  • →It lives on one floor. Wheels and a telescoping handle move its 75 lbB2.
  • →You run 12 V gear, like a cooler, from a car-style outlet the DELTA 4 (3000) doesn't have.
  • →You want it before December. It's on sale now at $1,100, and the DELTA 4 (3000) ships in early DecemberA10.

This is you — check the Elite 320 price

If neither fits

If your days look like Van Life Daily at 4,685 Wh, neither covers it and neither takes an extra battery. Start with an expandable unit, like the bigger DELTA 4, instead.

08

The Bottom Line

If everything you'd run at once fits under 1,800 W, buy the Elite 320. A slightly bigger battery, wheels, and far less per watt-hour.

If two big loads overlap, or the box lives at the bottom of a staircase, the DELTA 4 (3000) earns its price. Twice the inverter is the gap the Elite can't close.

Frequently Asked Questions

Answers drawn from the spec record and cited owner research.

How much is the EcoFlow DELTA 4 (3000), and when does it ship?

EcoFlow lists it at $1,699 on its US store and says it ships in early December. The BLUETTI Elite 320 sells for $1,100.

Which has the bigger battery, the DELTA 4 (3000) or the Elite 320?

The Elite 320, at 3,200 Wh against 3,072 Wh. That's 128 Wh apart. Neither one takes an extra battery, so what you buy is what you keep.

Can the BLUETTI Elite 320 run a space heater?

Yes, with Power Lifting, which runs resistive loads up to 2,700 W by giving them less power, so the heater warms more slowly. It still delivers no more than 1,800 W. At that rate the battery lasts about an hour and a half.

Which one is easier to move?

The DELTA 4 (3000) on stairs, the Elite 320 across a floor. The DELTA 4 (3000) is 57.3 lb and carries by two handles. The Elite 320 is about 75 lb but rolls on wheels with a telescoping handle.

Does the DELTA 4 (3000) have a 12 V car outlet?

No. EcoFlow lists no 12 V car socket on it. The Elite 320 has one, for a cooler or a tire pump.
