EcoFlow TITAN 5000 vs BLUETTI Apex 300 + 2×B300K
The Apex has the bigger 240 V plug but the TITAN has the bigger 240 V inverter, 7,200 W to 3,840 W, for less money; the Apex wins only when outages run long on small loads.

Spec deltas
The TITAN 5000 puts 7,200 W through a 30 A split-phase twist-lock. The Apex 300 bundle has the bigger plug, a 50 A NEMA 14-50R, and a smaller inverter behind it: 3,840 W shared across every outletA1A2B18. The TITAN also costs $500 less, and the Apex's answer to all of it is storage, 8,294.4 Wh across three boxes against one 5,017.6 Wh pack.
That plug is worth seeing through. 3,840 W at 240 V is 16 A, so the Apex's receptacle carries about a third of the current its shape advertises. The TITAN's L14-30 is matched to its inverter, since 7,200 W at 240 V is exactly 30 A. On a split-phase transfer panel, which is how EcoFlow bundles this unitA5, that's room for a 240 V load and the 120 V circuits together, where the Apex has to ration.
The catch: big watts drain a small tank fast. At full output the TITAN's 4,265 usable Wh last about half an hour, and in the 8-hour blackout the Apex wakes up with twice the nights in reserve. If your outages are long and your loads are small, the Apex is the better battery, and the TITAN's inverter is muscle you'll never flex.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
On a split-phase transfer panel, which is how EcoFlow sells the TITANA5, total output is the budget every circuit draws from. The TITAN's budget is nearly double, so a 240 V load can run while the 120 V circuits keep going. On the Apex, a 240 V load drawing near 16 A takes the whole 3,840 W and the rest of the house waits.
TITAN 5000: 7,200 W continuous, 120/240 V split-phase at 30 AA1TITAN 5000 outlets: three NEMA 5-20R plus one L14-30 marked 120V/240V 30AA2Apex 300 + 2×B300K: one NEMA 14-50R (120/240 V, 50 A), 3,840 W max in totalB18
Why it mattersIf a 240 V appliance has to run during an outage alongside everything else, the TITAN is the only one of the two with room for it.
The TITAN's inverter is a sprinter's gift. At the small, steady loads of a real blackout the extra watts sit idle, and the Apex's extra 3,276.8 Wh becomes twice the nights in reserve. For long outages lived on essentials, it's the better tool.
Usable energy after the 85% allowance: TITAN 4,265 Wh, Apex 7,050 WhContinuous output: TITAN 7,200 W, Apex 3,840 W8-Hour Blackout: Apex keeps 3.3 more nights in reserve, TITAN 1.6
Why it mattersIf you'll ration lights, fridge and internet through multi-day outages and never call on a big load, the Apex's storage beats the TITAN's output.
solar input
With panels on the roof, the storage gap narrows every sunny day, and one extra pack lifts the TITAN to 10,035.2 Wh (2 × 5,017.6), past the Apex bundle, at a price this page doesn't cover. The output gap never closes the other way: two B300K packs in, the Apex still tops out at 3,840 W.
TITAN 5000 solar: MPPT 40–450 V, 16 A, 4,000 W maxA3Apex bundle solar: 2,400 WTITAN expands to 30,105.6 Wh, six packs of 5,017.6 Wh eachA7
Why it mattersSolar households should treat the TITAN's smaller pack as a shortfall they can buy their way out of, and the Apex's 3,840 W as one they can't.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: Watts against watt-hours is this whole matchup, and the runtime table is where the Apex's storage earns its keep.
continuous output
At any load both can carry, the Apex runs about two-thirds longer, because 7,050 usable Wh outlasts 4,265. The TITAN's 7,200 W doesn't buy a single extra minute on a lamp or a fridge.
What a runtime table can't draw is the load only one of them can hold. Anything between 3,840 W and 7,200 W, or a 240 V draw past 16 A, runs on the TITAN and overloads the Apex. Read these hours as the price of the TITAN's headroom, then decide whether you'll ever use it.
Growth Path
Selected because: The TITAN's 4,000 W solar input and six-pack ceiling decide whether its smaller pack stays smaller.
solar input
Here the TITAN's smaller pack starts to look temporary. A 4,000 W solar input across a 40–450 V window refills it faster than the Apex refills its bigger one, and EcoFlow's label allows six packs, 30,105.6 Wh, on the same inverterA3A7. The Apex bundle expands with more of BLUETTI's packs too, but it already carries two and its output stays 3,840 W.
The 450 V ceiling also changes how a roof gets wired. 4,000 W through a 16 A input needs a string of at least 250 V (4,000 ÷ 16), so the TITAN wants long series strings, while an aggregation of owner reports says the Apex's 60 V input ceiling is its most common complaintB8. If the panels are going on the roof anyway, the TITAN is the easier array to build.
Your Life, Your Pick
Selected because: The blackout and daily-draw rows are the Apex's best case, and worth reading before you pay for watts.
Read the outage rows before falling for the watts. In the 8-hour blackout the Apex finishes with 5,405 Wh left, 3.3 more nights like it; the TITAN keeps 2,620 Wh, good for 1.6. Neither of those rows asks for more than 150 W at peak, so none of the TITAN's inverter shows up.
The daily-draw row is sharper: a 4,685 Wh day leaves the TITAN 420 Wh short while the Apex clears it with 2,365 Wh to spare. It's the conversion allowance tipping a near-pass under, but it repeats every day you live that way, and it's the clearest sign the Apex is the battery for long outages.

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 + 2×B300K 213.9 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.

Apex 300 + 2×B300K
Both survive the night. The Apex 300 + 2×B300K finishes at 23% used with 5,405Wh left — 3.3 more nights like it. The TITAN 5000 finishes at 39% with 2,620Wh, 1.6 more nights like it. If your outages tend to run past one evening, that difference is the whole argument between them.

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 + 2×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.

Conclusion
October 4, 2026
Verdict: the TITAN 5000
Take the TITAN 5000. It runs 7,200 W through a 30 A split-phase twist-lock, nearly double the Apex bundle's 3,840 W, takes 4,000 W of solar against 2,400 W, and costs $500 lessA1A3. The Apex's case is storage, 8,294.4 Wh against 5,017.6 Wh, and it's a real one: in the 8-hour blackout it keeps twice the nights in reserve. If your plan is rationing essentials through a multi-day outage, buy the Apex. If a 240 V load has to run while the rest of the house does, only the TITAN has the headroom.

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 + 2×B300K rates 3.4/5 (7th percentile of 29 Whole-Home / Off-Grid-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 TITAN 5000 (119 lbs) is a two-person lift. The Apex 300 + 2×B300K (213.9 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 95 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
Apex 300 + 2×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 + 2×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 + 2×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.

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.

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.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow TITAN 5000
The evidence so far is EcoFlow's own published ratings. They establish 7,200 W of split-phase output at 30 AA1 through three NEMA 5-20R sockets and an L14-30 twist-lockA2, a 5,017.6 Wh packA6, a 4,000 W solar input across 40–450 VA3, and a second AC port that passes up to 7,200 W through in bypass modeA14. The label sites the unit indoors in a utility spaceA10 and allows six packs, 30,105.6 WhA7, and our reading of its 204.8 V pack voltage points to LFP cellsA12. None of this is hands-on experience.
“7,200 W continuous output with 120/240 V split-phase at 30 A.”
BLUETTI Apex 300 + 2×B300K
The Apex's field record is short and centred on chargingB0. Posters in one DIY Solar Power Forum thread report units charging from the grid at different rates, one full while another sits at halfB1, say BLUETTI couldn't show them an Apex 300 charging above 1,200 WB2, and were told by support this is normal, which one called a bad sign for off-grid useB3. A roundup of owner reports adds the 60 V solar ceiling and a firmware bug that drops solar detection until the cables are repluggedB8B9.
The positives are real but narrower. One owner uses the 240 V output to charge a plug-in hybrid at 3.3 kW on the roadB5, and a reviewer cites a 20 W AC idle drain that stretches runtime across a long outageB15. Long-term data is missing: our research found nothing past about six months of ownershipB0.
“For me the 240V output is great. I can stick it in the back of my PHEV and use the 240V output to charge at 3.3KW when I stop.”

Who Should Buy Which
Buy the TITAN 5000 if you…
- →Your outage list includes a 240 V load on a two-pole breaker, and you want it running alongside the rest of the house rather than instead of it.
- →You're wiring into a split-phase transfer panel and want 7,200 W of budget behind it, not 3,840 W.
- →Panels are going on the roof, and you'd rather have a 4,000 W, 450 V input refilling a smaller pack than a 2,400 W one refilling a bigger pack.
- →A buyer whose permit or insurer asks for UL 9540: EcoFlow lists the TITAN 5000 as certified and tested to UL 9540AA15; check the Apex stack's listing for the same standard before you compare.
Buy the Apex 300 + 2×B300K if you…
- →Your outages run for days and you'll live on essentials: lights, fridge, router. In the 8-hour blackout the Apex keeps 3.3 nights in reserve to the TITAN's 1.6.
- →Your daily draw runs near 4,685 Wh, where the TITAN falls 420 Wh short and the Apex has 2,365 Wh left.
- →You want an RV plug at home: the Apex carries a TT-30R, and the TITAN 5000 has none.
If neither fits
If the plan is the whole house, central air and all, through days of outage with no sun, neither is the answer: flat out, the TITAN empties in about half an hour and the Apex in about two. Look at a standby generator, with or without a battery alongside it.
The Bottom Line
Take the TITAN 5000. The Apex's 50 A plug sits on a 3,840 W inverter; the TITAN's 30 A plug sits on 7,200 W, and it costs $500 less for the privilege. On a split-phase panel that's room for a 240 V load and the rest of the house at once.
Buy the Apex only if you know your outages are long, quiet and lived on essentials, because then its extra 3,276.8 Wh is worth more than watts you'll never call on. Everyone else should take the bigger engine and let the roof refill the smaller tank.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the Apex 300's 50 A outlet mean it can power more than the TITAN 5000?
No. The Apex's NEMA 14-50R is a 50 A receptacle, but the whole unit tops out at 3,840 W, which is 16 A at 240 V. The TITAN 5000's L14-30 is rated 30 A and its inverter fills it, 7,200 W at 240 V.
Which lasts longer in a power outage, the TITAN 5000 or the Apex 300 with two B300K?
The Apex, at any load both can carry. It stores 8,294.4 Wh against 5,017.6 Wh, and in the 8-hour blackout it finishes with 3.3 more nights in reserve against the TITAN's 1.6. The TITAN only wins on loads above the Apex's 3,840 W, which the Apex can't run at all.
Can I add more batteries to the TITAN 5000?
Yes, up to six packs and 30,105.6 Wh with EcoFlow's EF-TT-E5-G1 extra battery. One extra pack takes it to 10,035.2 Wh, past the Apex bundle's 8,294.4 Wh. The Apex also expands with BLUETTI's packs, but this bundle already includes two and still tops out at 3,840 W.
Does the Apex 300 have USB ports?
Not on the unit. Its two 100 W USB-C ports, two USB-A ports and 12 V output come with the Hub D1, which BLUETTI sells separately, and one reviewer called it an extra $300 to bolt on after the fact. The TITAN 5000 carries a 60 W USB-C and an 18 W USB-A port on the unit.
What does the TITAN 5000 add beyond the spec sheet?
EcoFlow lists it as UL 9540 certified and tested to UL 9540A, with a factory pre-wired Smart Home Panel 10 that controls 10 circuits from the app. Storm Mode charges the battery before severe weather, and X-Fusion 2.0 has solar power the home first with the battery covering peak-rate hours. EcoFlow's OASIS 3.0 is a subscription feature in the app.
