Head-to-head test
EcoFlow TITAN 5000 Classic vs BLUETTI Apex 300 + B500K
Two inverters within 160 W of each other, so the Classic's lower price is paid in battery and voltage: the BLUETTI holds 2,867 Wh more and lists a 240 V outlet the 120 V-only Classic doesn't have.

Spec deltas
The BLUETTI Apex 300 + B500K holds 7,884.8 Wh. The TITAN 5000 Classic holds 5,017.6 WhA5. That 2,867 Wh difference is the first thing the Classic gives up for costing $700 less, and the second is voltage: the Classic is 120 V onlyA1, while the Apex's record lists a 240 V outlet.
What the Classic doesn't give up is muscle. It runs 4,000 W continuous to the Apex's 3,840 W, a 160 W edge you'd never notice from the kitchen. So you're looking at two inverters of the same size bolted to different amounts of battery, and the bigger battery is the cheaper one per watt-hour.
That makes the Apex the pick for nearly anyone wiring backup into a house. The Classic keeps two honest arguments: a 3,200 W solar input that out-pulls the Apex's 2,400 WA3, and a smaller bill for a home where every circuit that matters runs at 120 V.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Expansion doesn't close it. Six Classic packs make 30,105.6 WhA6 and still not one volt of 240, because a pack adds watt-hours, not voltage. A well pump, dryer or central air on a 240 V breaker stays dark on the Classic at any size, while the Apex at least has the outlet, drawing on the same 3,840 W as everything else plugged in.
TITAN 5000 Classic: 4,000 W continuous at 120 V only, no 240 V split-phaseA1Apex 300 + B500K: 3,840 W continuous, one 240 V outlet on recordClassic expands to 30,105.6 Wh across six packsA6
Why it mattersIf anything on your must-run list sits on a 240 V breaker, cross the Classic off before price comes up.
Capacity
And it isn't expensive reserve. The $700 between them buys 2,867 Wh, and the Apex costs less per watt-hour than the Classic on our record. The Classic is the smaller check; the Apex is the better-priced battery.
Apex 300 + B500K: 7,884.8 Wh; TITAN 5000 Classic: 5,017.6 WhA58-Hour Blackout: the Apex ends with 5,057 Wh usable, 3.1 more nights like it; the Classic ends with 2,620 Wh, 1.6 more nightsCost per watt-hour on our record: the Apex is lower than the Classic
Why it mattersAnyone whose outages outlast one evening gets more from the extra money than the Classic's savings are worth.
solar input
With a big array on the roof, that shrinks the capacity gap to a question of cloudy days. A tank that refills in under half the time can be smaller and still keep up, so the Classic's real case is solar-first, all-120 V, and cheaper.
TITAN 5000 Classic solar input: 3,200 W max across 30–250 VA3Apex 300 + B500K solar input: 2,400 WClassic 5,017.6 Wh against Apex 7,884.8 Wh
Why it mattersA homeowner with a large array and no 240 V loads can take the Classic and let the panels cover the battery it lacks.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: The Apex's 2,867 Wh lead is the biggest spec gap on this page, and with the inverters this close, capacity decides how long the house stays on.
continuous output
Run the same house off both and the Classic taps out first, every time, by a margin worth more than half its own tank: the Apex holds 57% more. With the two inverters a wash, there's nothing on the output side that buys those hours back.
Runtime stops mattering only when something keeps refilling the battery, a solar array sized for the job or a generator. Without one, repeat the 8-Hour Blackout load night after night and the Classic runs dry during the third night (4,265 Wh usable at 1,645 Wh a night), while the Apex gets through a fourth on its 6,702 Wh.
Growth Path
Selected because: Both expand, and the Classic takes 3,200 W of solar to the Apex's 2,400 W, but every pack it adds is still 120 V only.
solar input
On growth, the Classic leads twice. It takes 3,200 W of solar across a 30–250 V windowA3, 800 W more than the Apex, and it scales to 30,105.6 Wh with six identical packsA6. The Apex expands too, with BLUETTI batteries, so neither one traps you at its starting size.
The catch is the one running through this whole page: the Classic grows at 120 V. Six packs make it last longer, not reach further. If a 240 V well pump is going on the backup list next year, the expansion path won't take you there.
Your Life, Your Pick
Selected because: The heavy-day row and the CPAP row show where the capacity gap bites and where it stops mattering.
The heaviest row is the one the Classic doesn't finish. A 4,685 Wh day leaves it 420 Wh short on the engine's flat 85% derate, though its nameplate 5,017.6 Wh would clear it, while the Apex covers the day with 2,017 Wh to spare. The Apex has margin where the Classic has a rounding argument.
The CPAP row shows the opposite. A night of CPAP uses 8% of the Classic and 5% of the Apex, so capacity decides nothing. The Classic's label also places it in a utility space, outside bedroomsA9, so it powers a CPAP from down the hall, not from the nightstand.
Brand Trust
Selected because: A unit that sits in a utility room for years makes each maker's support record part of the price.
Each maker's track record sends you to a different checkout. EcoFlow's support is US-based with a phone line but uneven in quality, and buying through Costco or Amazon gives you a stronger return net. BLUETTI's is mostly email on China hours and the least consistent in the category, and buying direct from BLUETTI tends to produce better support outcomes.
After the warranty, both get thin: EcoFlow offers no parts or service out of warranty, and BLUETTI has no spare-parts policy for some models. On a box you expect to keep for years, the purchase channel is part of the spec.

Scoring these two at a campsite is a category error: neither travels — the TITAN 5000 Classic is 102.5 lbs and the Apex 300 + B500K 183 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.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
TITAN 5000 Classic
A CPAP is about 40W for eight hours, so both of these cover the night several times over — capacity isn't the question here, and the percentages are a formality. What matters is the box next to your pillow, and the only published difference is a rating: the TITAN 5000 Classic is rated 30dB against the Apex 300 + B500K's 45dB. Each is the maker's own published rating, and the makers do not measure the same way, some quoting a best case and some a figure under load, so neither number describes a 40W draw and the two are not really comparable. Treat them as a reason to look for hands-on reports before either one goes next to a bed, not as a difference you can count on hearing.

Conclusion
October 4, 2026
Verdict: the BLUETTI Apex 300 + B500K
Buy the Apex 300 + B500K. Its 3,840 W inverter is within 160 W of the Classic's 4,000 W, so neither runs more of your house at once, and the extra $700 buys 7,884.8 Wh against 5,017.6 Wh plus a 240 V outlet the Classic can't offer at any sizeA1. On our record it's also the cheaper battery per watt-hour. The Classic is the right call for an all-120 V house where the budget stops at $2,599, especially one with a big solar array, since it takes 3,200 W of panels to the Apex's 2,400 WA3.
EcoFlow has not published this price yet. We priced the TITAN 5000 Classic at $2,599 from EcoFlow's pre-launch store listing, so treat it as an estimate. We will update this comparison when the price is published.

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, TITAN 5000 Classic rates 3.8/5 (32nd percentile of 20 Home Backup-class units), and Apex 300 + B500K rates 3.5/5 (11th percentile of 29 Whole-Home / Off-Grid-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.
Weight Reality Check
Neither unit is grab-and-go. The TITAN 5000 Classic (102.5 lbs) is a two-person lift. The Apex 300 + B500K (183 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's an 81 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
Apex 300 + B500K: 45dB Published
45dB is about as loud as a running refrigerator. The TITAN 5000 Classic is rated 30dB — lower, but published by a different maker measuring its own way, so the two figures are not a like-for-like gap. For most people, fan noise around 45dB and up is where sleep starts to suffer.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The Apex 300 + B500K is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The TITAN 5000 Classic 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. The Apex 300 + B500K's figure is a maximum rather than a guarantee — it depends 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 TITAN 5000 Classic works out at 1.9 years of cover per $1,000 spent against the Apex 300 + B500K's 1.5, but that spread is the price gap, not the terms.
Full record above — the Test Desk pick is the Apex 300 + B500K.

Analyst note
The TITAN 5000 Classic has no published cycle rating, so its lifetime rows use the average of the 28 LiFePO4 units EcoFlow does rate: about 3,400 cycles. That's a fair baseline for the brand but not a rating for this unit, so cost to own isn't scored on it. Judge these two on price, capacity and warranty, and read the rows marked "est." as a ballpark.
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 brings the bigger ecosystem, including a 120 V Smart Home Panel 10 sold to pair with the Classic. BLUETTI brings the value positioning, and on this pairing the value shows up as watt-hours: the Apex is the lower price per watt-hour of the two.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow TITAN 5000 Classic
The evidence for the Classic so far is EcoFlow's own rating label and store page, plus our arithmetic on themA0. They establish a 5,017.6 Wh pack shared with the TITAN 5000 and PlusA5, 4,000 W at 120 V onlyA1, three 120 V 20 A sockets and one 120 V 30 A portA2, 3,200 W of solar inputA3, a 30,105.6 Wh ceiling across six packsA6, and siting in a utility space rather than a living areaA9. By our count the 204.8 V pack works out to 64 cells in the LFP voltage rangeA11.
“4,000 W continuous output at 120 V only — no 240 V split-phase.”
BLUETTI Apex 300 + B500K
Field reports for this exact pairing are thinB0. Our research found none that confirm the B500K combination specifically, most describe the bare Apex 300 or its B300K bundle, and nothing covers six months of ownershipB0. Treat what follows as the base unit's character, not a verdict on this bundle.
On character, reviewers consistently describe the fans as even and tame under loadB1B2B13, and one owner singles out the 240 V output as a highlightB5. The weak spot is firmware: owners report an update that locked the unit in Backup modeB7 and another that ended in an inverter-output errorB9, though at least one app glitch cleared after a later updateB8.
“Turns out the Apex 300's noise control is on par with the quietest power stations on the market, like those on offer from EcoFlow and DJI.”

Who Should Buy Which
Buy the TITAN 5000 Classic if you…
- →The all-120 V house with panels on the roof: every circuit on your backup list is a standard breaker, and 3,200 W of solar inputA3 refills the Classic's 5,017.6 Wh faster than the Apex refills its bigger tank.
- →The buyer whose budget stops at $2,599 and who'd rather start at 5,017.6 Wh and add packs toward 30,105.6 WhA6 than pay for the capacity up front.
- →Someone building around EcoFlow's 120 V Smart Home Panel 10, the panel EcoFlow bundles with the ClassicA4.
- →The all-120 V house that already has rooftop solar: EcoFlow says the TITAN Series AC-couples with compatible existing panels via the Smart Home Panel 10 and a CT sensorA18.
Buy the Apex 300 + B500K if you…
- →The house with a well pump, dryer or central air on a 240 V breaker: the Apex lists a 240 V outlet, and the Classic has noneA1.
- →The family that loses power for two or three days at a stretch and wants the bigger reserve waiting after night one.
- →Anyone who'd rather spend the extra $700 on battery that's cheaper per watt-hour than keep it in the bank.
If neither fits
The camper looking for one box to carry to the truck should close this tab: the Classic's label puts it in a utility spaceA9, the Apex 300 + B500K weighs 183 lbs across its boxes, and a portable station you can lift with one hand is a different, far cheaper category.
The Bottom Line
Same-sized inverters, a battery 2,867 Wh bigger, and a 240 V outlet on only one side: the Apex 300 + B500K is the better home-backup buy, and on our record it's the cheaper battery per watt-hour too.
Take the Classic if your house is all 120 V and a big array will do the work its smaller tank can't. Otherwise, spend the difference and get the Apex.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the EcoFlow TITAN 5000 Classic run a 240V well pump?
No. The Classic is 120 V only, with no split-phase output, and adding expansion packs raises capacity, not voltage. If a well pump or other 240 V appliance is on your backup list, look at the Apex 300 + B500K, which lists a 240 V outlet, or at EcoFlow's split-phase TITAN 5000.
How much more battery does the Apex 300 + B500K have than the TITAN 5000 Classic?
2,867 Wh more: 7,884.8 Wh against 5,017.6 Wh, or 57% more. On an 8-hour blackout load, the Apex wakes up with 5,057 Wh usable against the Classic's 2,620 Wh.
Which recharges faster from solar, the TITAN 5000 Classic or the Apex 300 + B500K?
The Classic. It accepts up to 3,200 W across a 30–250 V input, against 2,400 W on the Apex. At full rated input that refills the Classic in about an hour and a half, while the Apex's bigger battery needs more than three hours at its ceiling.
Is the TITAN 5000 Classic worth buying over the Apex 300 + B500K to save money?
Only for an all-120 V home. The Classic saves $700, but its 4,000 W inverter is within 160 W of the Apex's 3,840 W, so the saving comes out of battery and voltage rather than output. If you need 240 V or more than a night of reserve, the Apex's extra cost buys more than the Classic saves.
What does the TITAN 5000 Classic add beyond the spec sheet?
EcoFlow lists the Classic as UL 9540 certified and tested to UL 9540A, with a factory pre-wired 120 V Smart Home Panel 10 that controls 10 circuits from the app. EcoFlow also says the TITAN Series AC-couples with compatible existing rooftop solar, using the panel and a CT sensor, and sells a 7-day installation service in limited ZIP codes. OASIS 3.0, with its 3-day solar forecast, is marked as a subscription feature in the EcoFlow app.
