Gunner’s take
Whole-Home Backup Tester
Set these two side by side and the spec sheets nearly cancel out.
The DELTA 4 (3000) holds 3,072 Wh and weighs 57.3 lbA1A7. BLUETTI's Elite 300 holds 3,014 Wh and weighs 58 lb. Both run on LFP cells rated for 6,000 cyclesA9B1, and both switch to battery in no worse than 10 ms when the grid drops.
The difference is the inverter, and it's a big one.
The DELTA 4 runs 3,600 W continuously at 120 V and surges to 7,200 WA2. The Elite 300 runs 2,400 W and surges to 4,800 W. That's half again the running power, from a box that weighs seven-tenths of a pound less.
You pay for those watts.
EcoFlow lists the DELTA 4 (3000) at $1,699 against $1,199 for the Elite, and it ships in early DecemberA10. A fridge, a furnace blower and a router, the loads I'd wire to a box this size, run together well under 2,400 W. If that's your list too, the Elite is the buy.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Below 2,400 W the two behave the same. Above it, only the DELTA 4 keeps going, and its 7,200 W surge gives a compressor or a pump more room to start, since a motor pulls two to three times its running draw for a moment at startup. For an RV the catch runs the other way: the Elite's socket takes an RV cord as it is, and the DELTA 4's twist-lock needs an adapter.
DELTA 4 (3000): 3,600 W continuous, 7,200 W surge, 120 VA2Elite 300: 2,400 W continuous, 4,800 W surgeDELTA 4 (3000): one 30 A twist-lock outletA3; Elite 300: an RV-style 30 A outlet
Why it mattersAdd up what you'd run at once. Under 2,400 W, the bigger inverter is money spent on a number you'll never reach.
weight
Not one of our six scenarios, from a CPAP night to a tailgate, asks either unit for more than 400 W. A sixth of the Elite's inverter covers the busiest of them. The DELTA 4's extra 1,200 W only earns its keep on loads none of these everyday jobs come near.
Capacity: 3,072 Wh against 3,014 Wh; weight: 57.3 lb against 58 lbBoth rated for 6,000 cyclesA9B1Busiest of our six scenarios peaks at 400 W
Why it mattersIf your plan looks like our scenarios, buy the Elite 300 and keep the difference.
What's left to separate them is the fan, and only EcoFlow has put a number on that. It's a ceiling EcoFlow publishes, not our measurement, and a 40 W CPAP sits far below the load that ceiling covers. BLUETTI's silence isn't proof the Elite is louder. It just leaves nothing to hold it to.
DELTA 4 (3000): 40 dB or less up to 1,800 W, by EcoFlow's figureA8Elite 300: no published noise figureCPAP Overnight: about 40 W, 12% of either battery
Why it mattersIf the box will sit beside your bed, the DELTA 4 is the one with a written promise about noise.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Every scenario goes the same way for both, and the busiest peaks at 400 W.
Nothing in our six scenarios makes either inverter work hard. The busiest, a tailgate, peaks at 400 W, a sixth of what the Elite can run. The 1,645 Wh blackout leaves 966 Wh in the DELTA 4 (3000) and 917 Wh in the Elite 300, a 49 Wh difference nobody will feel.
Van Life Daily beats both by the same margin. It asks for 4,685 Wh, and they fall 2,074 Wh and 2,123 Wh short. Neither takes an extra batteryA6, so a day like that needs a bigger class of box or a second power source.
What the Specs Don't Tell You
Selected because: Two heater modes, and only one of the two units publishes how loud it gets.
Both makers built a heater trick, and neither helps a motor. BLUETTI's Power Lifting runs a resistive load rated up to 4,800 W by feeding it less than it asks for. EcoFlow's X-Boost works the same way and switches off while the unit charges from the wall or runs in bypassA2. For a compressor or a pump, the numbers that count are the surge peaks, 7,200 W against 4,800 W.
Only one of these tells you how loud it gets. EcoFlow rates the DELTA 4 at 40 dB or less up to 1,800 W and 50 dB or less at the full 3,600 WA8. BLUETTI publishes nothing for the Elite. Those are EcoFlow's ceilings, not our measurement, but a published ceiling beats a blank when the box lives in a bedroom.
Brand Trust
Selected because: With hardware this close, the company that answers when it breaks counts for more than usual.
When the hardware is this close, the support line becomes part of the spec. Our brand file rates EcoFlow's US support as polarized, with phone, email and chat on offer. It rates BLUETTI's as the least consistent in the category, mostly email and running on China's clock. Neither is a reason to skip the brand. Each changes where I'd buy.
Buy the Elite direct, and register the DELTA. BLUETTI support goes better when you bought from BLUETTI, and its five-year term depends on buying direct or registering. EcoFlow's five years is three plus two once you register it in the EcoFlow appA9, and buying it through a big retailer gives you an easier return if the first unit is bad.
Portability & Form Factor
Selected because: 57.3 lb against 58 lb, and both makers claim the smallest box in the class.
weight
Seven-tenths of a pound is all the scale can find. Both are a one-adult lift into a trunk. The DELTA 4 carries by a handle at each end, and EcoFlow sells its folding cart as a separate purchaseA7.
Both makers claim the smallest box, and both can be right. The Elite 300 was certified the smallest 3 kWh station by volume as of January 2026B2. EcoFlow calls the DELTA 4 the smallest and lightest in its class, then defines the class as 3 kWh and 3,600 WA7, which leaves the Elite out on its inverter alone. Our record has no dimensions for the Elite, so I can't settle it with a tape measure.

Conclusion
November 4, 2026
Verdict: the BLUETTI Elite 300
I'd buy the Elite 300, unless you run more than 2,400 W at once. The two hold 3,072 Wh and 3,014 Wh, weigh 57.3 lb and 58 lb, and are both rated for 6,000 cyclesA9B1, so the $500 between $1,699 and $1,199 mostly buys one thing: a 3,600 W inverter against 2,400 W. The DELTA 4 (3000) also charges from the wall at up to 1,800 WA4 and publishes a noise ceiling the Elite doesn'tA8. The Elite takes 200 W more solar, has a 12 V car socket and an RV outlet, and is already in owners' handsB4, while the DELTA 4 ships in early DecemberA10. If your heaviest moment stays under 2,400 W, the extra money buys headroom you won't touch.

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 3000 Gen4 rates 4.8/5 (86th percentile of 29 Large-class units), and Elite 300 rates 4.6/5 (75th percentile of 29 Large-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Elite 300: Power Lifting to 4,800W
The Elite 300 has BLUETTI's Power Lifting mode, which runs a resistive appliance rated up to 4,800W from its 2,400W 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 300's separate 4,800W surge peak, not this one. And it is not a reason to size down, because running a load that big from 3,014Wh 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.
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 300 works out at 4.2 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.
Elite 300: Noise Level Not Disclosed
The DELTA 3000 Gen4 publishes its noise level (40dB); the Elite 300 doesn't publish one. That isn't evidence the Elite 300 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 300 before deciding.
Full record above — the Test Desk pick is the Elite 300.

Analyst note
The Elite 300 wins on both sticker price and long-term value. At $0.07/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. 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.
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.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3000 Gen4
Nobody in the US owns a DELTA 4 (3000) yet. EcoFlow put it on sale on November 4 and says it ships in early DecemberA10, so everything here comes from EcoFlow's US store and spec sheet, plus our own arithmeticA2A4A8.
I'd want to set it beside a bed running a CPAP and listen. EcoFlow says it stays at 40 dB or less up to 1,800 WA8, and a CPAP draws about 40 W, so it should sit far below that ceiling all night. I'd want to hear whether its fans spin up at all, with the Elite running the same machine on the other side of the room.

“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 3000 Gen4 if you…
- →Your load tops 2,400 W at once. Only the DELTA 4 (3000) carries more, up to 3,600 W.
- →You start big motors. Its surge peaks at 7,200 W against 4,800 W.
- →You recharge from the wall between outages. It takes up to 1,800 W, the full 15 A of an ordinary circuitA4.
- →It will sit by your bed. It's the only one of the two with a published noise ceilingA8.
Buy the Elite 300 if you…
- →Your heaviest moment stays under 2,400 W. Then the Elite does everything the DELTA 4 does here for $500 less.
- →You charge mostly from the sun. It takes 1,200 W of solar against 1,000 W.
- →You travel in an RV. Its 30 A outlet is the RV kind and it has a 12 V car socket. The DELTA 4 has no car socket, and its 30 A outlet is a twist-lockA3.
- →You want it before December. The Elite is already in owners' handsB4, and the DELTA 4 ships in early DecemberA10.
If neither fits
If you need 240 V, skip both. Neither has a 240 V outlet, so a 240 V well pump or dryer needs a home backup system that has one.
The Bottom Line
I'd buy the Elite 300. The same battery to within a rounding error, the same rated life, the same weight on your arms, and the lower price.
Pay for the DELTA 4 (3000) only for its inverter. 3,600 W and a 7,200 W surge are real, and so is a published noise ceiling. If nothing you own pulls past 2,400 W at once, the Elite does the job for $500 less.
Frequently Asked Questions
