EcoFlow TITAN 5000 vs BLUETTI Apex 300 + B300K
This page is decided in watts, not watt-hours: the TITAN 5000 runs 7,200W of split-phase power, nearly double the Apex's 3,840W, and that is the ceiling a 240V home panel hits first.

Spec deltas
Seven thousand two hundred watts against 3,840. The TITAN 5000 nearly doubles the Apex 300 + B300K's continuous output and delivers it as 120/240V split-phase through an L14-30 twist-lockA1A2. Thirty amps at 240 volts works out to exactly 7,200W, so the outlet and the inverter are sized to each other with nothing stranded.
The Apex comes back with a bigger tank and a smaller bill: 5,529.6Wh to 5,017.6Wh, at $2,599 against $3,199. For a house whose essentials are a fridge, the internet and a few lights, it's the better buy, and nobody should pay $600 for headroom they'll never draw.
Whole-home backup through a 240V panel is a different job. EcoFlow sells the TITAN 5000 with its 240V Smart Home Panel 10A5, and that pairing is the point: this is a box meant to carry several circuits at once, and the Apex's 3,840W is the number those circuits run into first.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Whole-home backup isn't one big load; it's several medium ones overlapping on their own schedule. With 3,360W more headroom, the TITAN keeps a well pump running while the fridge and furnace blower are already going. On the Apex, a stack like that is where you start deciding which circuit waits.
TITAN 5000: 7,200W continuous, 120/240V split-phase at 30AA1Its 240V outlet is one L14-30 marked 120V/240V 30AA2Apex 300 + B300K: 3,840W continuous across all its outlets
Why it mattersIf you're wiring a 240V transfer panel and want several circuits live together, the TITAN 5000 is the one sized for the job.
solar input
In an outage that lasts days, recharge is a survival spec. Once your panels add up to more than 2,400W, only the TITAN can use the excess, and on a good day that's the difference between finishing the afternoon full or not. Below 2,400W of panels, the solar ceiling stops mattering.
TITAN 5000 solar input: 40–450V, up to 4,000WA3EcoFlow's display image shows 4.00kW inA4Apex 300 + B300K solar input: 2,400W
Why it mattersAnyone planning more than 2,400W of panels should count the solar input as a TITAN point.
Capacity
For a buyer whose loads are 120V and modest, those are the specs that actually get used, while the TITAN's split-phase headroom sits idle. That buyer keeps the price difference and gets a battery that goes further on a heavy day.
Apex 300 + B300K: 5,529.6Wh to the TITAN 5000's 5,017.6WhVan Life Daily asks 4,685Wh: the Apex ends with 15Wh, the TITAN 5000 falls 420Wh shortThe Apex lists a 30A RV outlet; the TITAN 5000 has none
Why it mattersIf nothing you'll back up sits on a 240V breaker and your peak stays under 3,840W, save the money and take the Apex.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: Output decides what can run together: 7,200W against 3,840W matters more here than the 512Wh capacity gap.
continuous output
Runtime and output pull in opposite directions on this page. The Apex stores more, 4,700Wh usable after the derate against 4,265Wh, so a light load lasts longer on it. The TITAN has the higher ceiling, so a heavy load runs on it that the Apex can't carry at all.
For whole-home use, the ceiling is what you hit first. Stack a 240V circuit on top of the kitchen and the furnace and 3,840W stops looking generous; the overload ends the evening before the Apex's extra hours ever come into play.
Growth Path
Selected because: 4,000W of solar to 2,400W, plus a ceiling of 30,105.6Wh, shapes how each one scales.
solar input
The TITAN's label allows six identical packs, 30,105.6Wh in allA7, fed by a 40–450V solar input up to 4,000WA3. Against the Apex's 2,400W from the roof, that's the bigger growth story on both axes at once: more bank, and a faster way to fill it.
The 450V window is the quiet advantage for anyone wiring a serious array: higher string voltage means less current in the cable for the same power. It's not a reason to buy on its own, but it's one more sign the TITAN is built to sit at the center of a large system.
Your Life, Your Pick
Selected because: Most rows are easy for both; the 4,685Wh Van Life day goes to the Apex's bigger tank.
Most of the table says both units are overqualified. An 8-hour blackout uses 39% of the TITAN and 35% of the Apex, and a remote workday barely dents either.
The exception is Van Life Daily, a 4,685Wh day the Apex finishes with 15Wh while the TITAN runs 420Wh short. That's the Apex's bigger tank doing its one job well, and it's the honest catch on our pick: 7,200W of output doesn't make 5,017.6Wh last any longer.
Brand Trust
Selected because: A whole-home battery stays in the house for years, so the support record behind it is part of the purchase.
EcoFlow is the brand with a whole-home system built around this unit: the TITAN 5000 is sold in bundles with EcoFlow's 240V Smart Home Panel 10 and marketed as whole-home backupA5. BLUETTI's profile leans on value instead, with some of the lowest cost per Wh in the catalog, which is the Apex's whole pitch on this page.
EcoFlow's caveats are about policy: it tested subscription paywalls on advanced app features in early 2025 before pulling back, and it stops at the warranty line with no parts afterwards. BLUETTI's are about people, with email-first support that varies widely from one case to the next.

Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Scoring these two at a campsite is a category error: neither travels — the TITAN 5000 is 119 lbs and the Apex 300 + B300K 148.8 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
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 is rated 39dB against the Apex 300 + B300K'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.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h

Either unit
Both power your workstation all day without strain. At these utilization levels the real difference is USB-C for direct laptop charging — 100W on the Apex 300 + B300K against 60W — which beats the inverter for convenience and wastes less energy.

Van Life Daily

Apex 300 + B300K
The TITAN 5000 doesn't finish — 4,265Wh usable against the 4,685Wh this needs leaves it 420Wh short, about 91% of the scenario covered (its nameplate 5,018Wh actually clears this — the flat 15% conversion allowance is what tips it under). The Apex 300 + B300K covers it with only 15Wh left — well under half a percent of what the day asks, so it finishes with nothing behind it.

Conclusion
October 4, 2026
Verdict: the EcoFlow TITAN 5000
Buy the TITAN 5000. It delivers 7,200W continuous at 120/240V split-phaseA1 against the Apex 300 + B300K's 3,840W, so with a well pump, the fridge and the furnace blower all running, there's 3,360W more room before something has to wait. It also takes 4,000W of solar to 2,400WA3 and grows to 30,105.6WhA7. The Apex stores 512Wh more and costs $600 less; if your must-run circuits never add up past 3,840W, that's the better deal.

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 rates 4.6/5 (79th percentile of 20 Home Backup-class units), and Apex 300 + B300K rates 4.3/5 (58th percentile of 20 Home Backup-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 (119 lbs) is a two-person lift. The Apex 300 + B300K (148.8 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 30 lb difference.
Apex 300 + B300K: 45dB Published
45dB is about as loud as a running refrigerator. The TITAN 5000 is rated 39dB — 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 + B300K 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 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 + B300K'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.
Full record above — the Test Desk pick is the TITAN 5000.

│ warranty ends · Reaching the cycle rating means ~80% capacity remains — degraded, not dead. est. = no published cycle rating; the brand’s average is used instead.
Analyst note
The TITAN 5000 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 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.

Analyst note
Both expand, but the TITAN 5000's higher solar ceiling (4,000W vs 2,400W) gives it the stronger off-grid growth path — more panels can feed a bigger bank as it grows.

The Apex's record is early: reviewers on test units, with no owner threads on this exact bundle and no longevity dataB0. Its heaviest test speaks to this page directly. A washing machine took about an hour and 35% of the charge, and a heat pump dryer pulled it on down to 20%B9B10; one reviewer said it felt like it could genuinely replace a generatorB4.
The gap reviewers point at is low-voltage power: the Apex 300 offers six AC plugs and high-voltage connectors with no USB or DC of its ownB1, and the B300K's USB-C managed only 8W into one reviewer's phoneB6.
“The Apex 300 doesn't have USB ports, DC ports, or much of anything beyond its six AC plugs and high-voltage connectors.”

Who Should Buy Which
Buy the TITAN 5000 if you…
- →You're wiring a 240V transfer panel and want the well pump, fridge and furnace blower live together: 7,200W of split-phase through an L14-30A1A2.
- →You're planning more than 2,400W of panels, or a bank that grows toward six packs: 4,000W of solar input and a 30,105.6Wh ceilingA3A7.
- →You already have rooftop solar on a house with a 240V panel: EcoFlow says the TITAN Series AC-couples with compatible existing panels via the Smart Home Panel 10 and a CT sensorA19.
Buy the Apex 300 + B300K if you…
- →Your backup list is 120V circuits whose combined draw stays under 3,840W, and you'd rather keep the difference in price.
- →You have an RV or van with a 30A RV inlet: the Apex has the matching outlet, and the TITAN 5000 has none.
- →You care more about how long a light load lasts than how much can run at once: 5,529.6Wh to 5,017.6Wh.
If neither fits
If you can't touch your home's wiring, in a rental or a condo, the TITAN's split-phase advantage is unreachable and the Apex is more box than a few extension cords need; a mid-size portable station is the honest fit. And if the goal is the whole house, central air and all, through a long outage, a standby generator does that job better than any battery on this page.
The Bottom Line
Buy the TITAN 5000. On a 240V panel the thing that runs out first is watts, and it carries 7,200 of them through a twist-lock rated for exactly that, against 3,840W on the Apex.
The Apex 300 + B300K is the smarter spend for a 120V house with modest peaks: more tank, less money. But if you're wiring circuits rather than plugging in appliances, buy the machine that can run them all at once.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the EcoFlow TITAN 5000 have 240V output?
Yes. EcoFlow's rating label gives it 7,200W at 120/240V split-phase, 30A, through an L14-30 twist-lock alongside three 120V 20A sockets. Its AC IN/OUT port also takes split-phase input and can pass up to 7,200W through to the outlets in bypass mode.
Is the TITAN 5000 more powerful than the BLUETTI Apex 300 + B300K?
On continuous output, by a wide margin: 7,200W to 3,840W. The Apex stores more, 5,529.6Wh to 5,017.6Wh, so a small load runs longer on it. The TITAN carries far more at once, which is what a whole-home panel needs.
How fast does the TITAN 5000 recharge from solar?
Its solar input takes 40–450V and up to 4,000W, and EcoFlow's display image shows 4.00kW in. On paper, 5,017.6Wh at 4,000W is under an hour and a half of full-rated input, though real panels rarely hold their rating all day. The Apex 300 + B300K tops out at 2,400W from solar.
Can the TITAN 5000 charge from a normal wall outlet?
Yes, through a 100–120V inlet at up to 15A, with draws above 12A limited to under three hours. The faster grid path is the AC IN/OUT port, which accepts 120/240V split-phase input at up to 30A.
What does the TITAN 5000 add beyond the spec sheet?
EcoFlow says the TITAN Series AC-couples with compatible existing rooftop solar, using the Smart Home Panel 10 and a CT sensor. X-Fusion 2.0 runs solar to the house first and the battery at peak rates, and EcoFlow says it can power loads beyond the backed-up circuits through the main panel. Storm Mode charges the battery before severe weather, with switchover under 20 ms.
