Gunner’s take
Whole-Home Backup Tester
The DELTA Pro Ultra does one thing the Apex 200 + B300K can't: it puts out 240V. BLUETTI built the Apex 200 for 120V only and sends buyers who need 120/240V to the Apex 300B2. If your outage plan includes a well pump, an electric dryer or central air, check that first.
If it doesn't, the comparison turns on what you'd pay for headroom. The DELTA Pro Ultra runs 7,200W to the Apex system's 3,600W, holds 819Wh more and takes 5,600W of solar to 3,000W. The Apex system costs $2,000 less, weighs 57 lb less and is rated for 6,000 cycles to the DELTA Pro Ultra's 3,500.
One more difference sits in the fine print. EcoFlow classifies the DELTA Pro Ultra as no-break, an online UPS that runs the load through the inverter all the timeA3. BLUETTI lists a UPS mode on the Apex 200, off by default, with a switchover of 15ms or lessB10. That is a short gap, but it is still a gap. For a desktop computer or medical equipment, no-break is the safer design.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
So 240V settles this page before anything else does. Owner reviews credit the EcoFlow with running a 3-ton central air conditionerA4, a load the Apex can't reach. In a house that only needs a fridge, lights and a furnace fan through an outage, the extra 3,600W of continuous output would sit unused.
DELTA Pro Ultra: 240V output, 7,200W continuous, 10,800W surgeApex 200: 120V only; BLUETTI points buyers who need 120/240V to the Apex 300B2Home Depot owner reviews credit the DELTA Pro Ultra's 7,200W inverter with running a 3-ton central ACA4
Why it mattersBefore reading further, check your breaker panel for double-pole breakers, the wide ones that feed 240V circuits, on the loads you need in an outage.
cost / lifetime kWh
Pair that with the lower price and the Apex system costs $0.07 per lifetime kWh against $0.20 for the DELTA Pro Ultra, about a third as much. If you plan to cycle the battery daily against time-of-use rates, which the BLUETTI app schedulesB11, that's the figure that pays the bill.
DELTA Pro Ultra: 3,500 rated cycles on 6,144WhApex 200 + B300K: 6,000 rated cycles on 5,325WhCost per lifetime kWh: $0.20 vs $0.07
Why it mattersDaily cyclers who don't need 240V should treat this as the deciding number.
solar input
That matters most if you're building toward whole-home backup with more batteries later, which is where EcoFlow aims itA1. For a modest array the Apex gives up less than the numbers suggest: its high-voltage input takes panels wired for higher voltage at the end of a long cable run, in the base unit, with no extra hardwareB5B16.
DELTA Pro Ultra: 5,600W solar inputApex 200 + B300K: 3,000W solar input, 2,000W of it through a 60 to 280 V high-voltage inputB5Capacity: 6,144Wh vs 5,325Wh
Why it mattersBuyers planning a big array for a growing bank should lean EcoFlow; buyers with a few panels on a shed roof lose little with the Apex.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The less expensive system here is also rated for more cycles, so the cost of owning them splits further than the sticker.
cost / lifetime kWh
The Apex system is the cheaper one to own by a wide margin, $0.07 per lifetime kWh against $0.20. It gets there from two directions at once: it costs $2,000 less, and BLUETTI rates it for 6,000 cycles to EcoFlow's 3,500.
The warranty is where the DELTA Pro Ultra pulls one back. EcoFlow gives it 5 years, and BLUETTI hasn't published a term for the Apex 200B13. On a system this size, I'd want to see that term before spending the money.
Growth Path
Selected because: Both expand, and the question is which one ends where your house needs it to.
solar input
The DELTA Pro Ultra is built to grow into whole-home backup, up to 90kWh across a system by EcoFlow's figureA1, with 5,600W of solar input to feed it. The Apex 200 grows too, to six B300K or B500K batteries and 33.28 kWh per unit, with two or three units linking through BLUETTI's Hub A1 to 6,000WB9.
Both are real paths. The EcoFlow's runs toward a whole house with 240V circuits on it. The BLUETTI's runs toward a very large 120V system, which is plenty for most outages and useless for a well pump that needs 240V.
Portability & Form Factor
Selected because: Neither moves after install day, but one is 57 lb lighter to get there.
weight
Both of these are installs. The DELTA Pro Ultra is 181.8 lb as EcoFlow's modular systemA0. The Apex system is 124.5 lb, split between the 59.5 lb base unit and a B300K of about 65 lbB8B21.
You'll move either one twice in its life, into place and out again when you sell the house. The Apex is the one you can probably manage without calling a friend.
Brand Trust
Selected because: The two brands' support records differ more than their batteries do, and you'll own either one for a long time.
EcoFlow offers US phone, email and chat support, and buying through a big retailer adds a return safety net on top. BLUETTI's support runs mostly by email and has the least consistent record of the major brands, though buying direct from BLUETTI tends to go better.
On a battery you'll own for a decade, that's worth weighing. If I bought the Apex, I'd buy it from BLUETTI directly and register it the same day.

Scenario verdicts
We ran the math on six real-world scenarios. Here's which unit survives your actual life.
SCN-01 · 2 nights · needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Scoring these two at a campsite is a category error: neither travels — the DELTA Pro Ultra is 181.8 lbs and the Apex 200 + B300K 124.5 lbs, and at those weights they roll off a truck bed if they go anywhere at all. The 2,100Wh here is trivial for either — it's the going that doesn't happen. If you need power away from the building, you're shopping the wrong class.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Either unit
Both get through the night with most of the battery left. The difference is the switchover. EcoFlow classifies the DELTA Pro Ultra as no-break, and BLUETTI prints a switchover of 15ms or less for the Apex 200. If a desktop is running when the lights go out, that's this row's real question.

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. What would separate them is fan noise, but Apex 200 + B300K 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.
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 Apex 200 + B300K against 100W — which beats the inverter for convenience and wastes less energy.

Neither unit
Scoring these two at a tailgate is a category error: neither travels — the DELTA Pro Ultra is 181.8 lbs and the Apex 200 + B300K 124.5 lbs, and at those weights they roll off a truck bed if they go anywhere at all. The 670Wh here is trivial for either — it's the going that doesn't happen. If you need power away from the building, you're shopping the wrong class.

Van Life Daily
A full day of mobile living — the ultimate endurance test
DELTA Pro Ultra
On capacity this row goes to the DELTA Pro Ultra, which finishes a 4,685Wh day with 537Wh to spare. The Apex system falls 159Wh short after the conversion allowance, one small appliance's worth. At these weights neither is a natural van battery.

Conclusion
November 4, 2026
Verdict: the BLUETTI Apex 200 + B300K
Unless your house needs 240V, take the Apex 200 + B300K. It covers a 120V outage with 5,325Wh, 3,600W and a 6,000-cycle rating for $2,000 less, and it costs less per lifetime kWh, $0.07 against $0.20. The DELTA Pro Ultra earns its price in one situation: a home with 240V loads that need 7,200W and a 10,800W surge rating behind them. If that's your house, the Apex 200 can't serve those circuits at all, because BLUETTI built it for 120V onlyB2.

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 Pro Ultra rates 4.9/5 (95th percentile of 22 Home Backup-class units), and Apex 200 + B300K rates 4.4/5 (62nd percentile of 22 Home Backup-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Weight Reality Check
Neither unit is grab-and-go. The Apex 200 + B300K (124.5 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. The DELTA Pro Ultra (181.8 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 57 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
UPS Switchover: 0ms-rated vs ≤15ms
Both list a UPS mode, at different rated speeds. The DELTA Pro Ultra is rated 0ms — a no-break design on paper, which is the maker's classification rather than a stopwatch result. The Apex 200 + B300K is rated ≤15ms — 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.
Battery Lifespan in Real Years
BLUETTI rates the Apex system for 6,000 cycles and EcoFlow rates the DELTA Pro Ultra for 3,500. At a full cycle every day, that's 16.4 years against 9.6. Reaching the rated count doesn't end either battery. It marks the point where capacity has faded to the maker's stated end-of-life level, and both keep working past it.
Apex 200 + B300K: Noise Level Not Disclosed
The DELTA Pro Ultra publishes its noise level (30dB); the Apex 200 + B300K doesn't publish one. That isn't evidence the Apex 200 + B300K 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 Pro Ultra's 30dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the Apex 200 + B300K before deciding.

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 sells the DELTA Pro Ultra as the top of its whole-home line, and BLUETTI pitches the Apex 200 as the value step into a home system. Support is the clearer split. EcoFlow offers US phone, email and chat, while BLUETTI runs mostly on email with less consistent results, which improve when you buy direct.

“80% of 2,560 Wh is 2,048 Wh. Delivered in 45 minutes from empty that averages about 2,700 W, nearly twice what a 15 A, 120 V wall outlet supplies (1,440 W), and faster than BLUETTI's own 1.6 hours through a 30 A campground cable. Treat the 45 minutes as unconfirmed until BLUETTI says where it starts and what circuit it needs.”

“The Apex 300's solar inputs top out at 60 V, so an array a long cable run from the house either loses power in the cable or needs BLUETTI's $699 Solar X 4K. The Apex 200's 60–280 V high-voltage input takes the same panels wired for more volts and less current, in the base unit.”

Who Should Buy Which
Buy the DELTA Pro Ultra if you…
- →Your house has 240V loads, a well pump, a dryer or central air, that have to keep running in an outageA4.
- →You're building toward whole-home backup with a large solar array and more batteries laterA1.
- →You run sensitive electronics or medical equipment and want a published no-break UPS classificationA3.
Buy the Apex 200 + B300K if you…
- →Your outage list is all 120V: fridge, freezer, lights, internet and a furnace fan.
- →You'll cycle the battery daily on solar or time-of-use rates, where its 6,000-cycle rating does the most workB1B11.
- →You want the travel trailer's 12 V gear on a 12 V/30 A Anderson port on the same system that backs up the houseB4.
If neither fits
You want something to take camping. Both of these are installs that stay where you put them, and a single box you can carry with one hand is the category to look at.
The Bottom Line
Check for 240V loads first. If your house has them, buy the DELTA Pro Ultra, because the Apex 200 can't serve them at any price. If it doesn't, buy the Apex 200 + B300K: it covers a 120V outage with room to spare, costs $2,000 less and is rated for far more cycles. I'd keep the difference and spend some of it on panels.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DELTA Pro Ultra worth it over the BLUETTI Apex 200 + B300K?
Only if you need 240V or more than 3,600W. The DELTA Pro Ultra delivers both, with 7,200W continuous. If your loads are all 120V, the Apex system does the job for $2,000 less and is rated for more cycles.
Can the BLUETTI Apex 200 run 240V appliances?
No. BLUETTI built the Apex 200 for 120V only and points buyers who need 120/240V to the Apex 300. The DELTA Pro Ultra has a 240V output.
Which is cheaper to own over its life, the DELTA Pro Ultra or the Apex 200 + B300K?
The Apex 200 + B300K, at $0.07 per lifetime kWh against $0.20. It costs less up front, and BLUETTI rates it for 6,000 cycles to the DELTA Pro Ultra's 3,500.
How heavy are the DELTA Pro Ultra and the Apex 200 + B300K?
The DELTA Pro Ultra weighs 181.8 lb. The Apex 200 + B300K weighs 124.5 lb in total, split between the 59.5 lb Apex 200 and a B300K of about 65 lb. Neither is portable in any everyday sense.
