EcoFlow TITAN 5000 vs BLUETTI AC300 + 4×B300
The BLUETTI holds almost two and a half times the energy but can't put a watt on a 240 V circuit, while the TITAN 5000 runs 7,200 W split-phase, so the call turns on whether your house has a 240 V load you'd miss in an outage.

Spec deltas
The BLUETTI AC300 + 4×B300 has a 240 V problem no amount of battery can fix: its record lists no 240 V output, so nothing on a two-pole breaker will run from it. The TITAN 5000 outputs 120/240 V split-phase at 7,200 WA1, with an L14-30 twist-lock rated 120/240 V, 30 A on the frontA2. If your house has a 240 V well pump, you can stop reading here.
The arithmetic is tidy. 240 V at 30 A is 7,200 W, the inverter's full rating, so the TITAN can hand its entire output to one 240 V circuit. The BLUETTI's 3,000 W at 120 V is 25 A. One of these feeds both legs of a home panel; the other feeds a set of 120 V circuits and stops there.
What the BLUETTI does have is storage: 12,288 Wh against the TITAN's 5,017.6 WhA6, almost two and a half times as much. In the engine's 8-hour blackout it finishes with 5.3 more nights left in it, against 1.6 for the TITAN. If every load you care about is 120 V and modest, that buffer is a real argument. If any of them is 240 V, it isn't one.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Through EcoFlow's 240 V Smart Home Panel 10, which the TITAN is bundled withA5, the well pump, the dryer or a central-air condenser can stay on the backed-up list. With the BLUETTI those circuits fall off the list entirely, however much energy it has in reserve.
TITAN 5000: 7,200 W continuous, 120/240 V split-phase at 30 AA1TITAN 5000 outlet: L14-30 twist-lock marked 120V/240V 30AA2BLUETTI AC300 + 4×B300: 240 V outlets 0, 3,000 W continuous
Why it mattersAny household with a 240 V load it can't do without for a day should stop comparing capacity and buy the TITAN.
Capacity
That's the BLUETTI's case, and it holds only while the load stays light and on 120 V. Its 3,000 W ceiling caps what can run at once, so the extra nights buy duration, not reach. The TITAN makes the opposite trade: less time per charge, but more than twice the load at once and the 240 V circuits on top.
BLUETTI: 12,288 Wh, 10,445 Wh usable after the flat 85% derateTITAN 5000: 5,017.6 WhA6, 4,265 Wh usable8-Hour Blackout (1,645 Wh): BLUETTI 5.3 more nights, TITAN 1.6
Why it mattersA household riding out long outages on a fridge, lights and the internet, with nothing on 240 V, is the one buyer who should take the BLUETTI's extra nights over the TITAN's extra watts.
solar input
A small tank behind a big tap behaves differently in an outage. With a full array, the TITAN can carry a daytime load off the panels and still have its pack full by evening, then spend the night on battery. The BLUETTI carries more into the dark, but a cloudy stretch leaves it climbing back slowly at 2,400 W.
TITAN 5000 solar input: 4,000 W max across 40–450 VA3EcoFlow's product image shows the display at 4.00 kW inA4BLUETTI solar input: 2,400 W max into 12,288 Wh
Why it mattersIf your outage plan is panels on the roof rather than nights on a full tank, the TITAN's 4,000 W input makes it the better solar system.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Every scenario here peaks at 400 W or less, which shows the BLUETTI's storage at its best and never asks for 240 V.
Read these rows for what they measure, which is stored energy. The BLUETTI takes the 8-Hour Blackout, the Remote Workday and Van Life Daily, and the CPAP night is a tie at 8% used against 3%. None of these loads comes near 3,000 W, so none of them tests the one thing the BLUETTI can't do.
Van Life Daily is the row to notice. At 4,685 Wh it leaves the TITAN's single pack 420 Wh short after the 85% derate, covering about 91%, while the BLUETTI finishes at 45% used. A daily draw that size calls for a second TITAN pack, or for the BLUETTI if your loads are all 120 V.
Runtime: Will It Power Your Gear?
Selected because: The BLUETTI's 10,445 usable Wh against the TITAN's 4,265 is the honest counterweight to the 240 V argument.
continuous output
Hour for hour, the BLUETTI simply has more in the tank: 10,445 Wh usable against 4,265 Wh, on the same flat 85% allowance. Whatever appliance the table lists, the BLUETTI runs it a little under two and a half times as long.
What the table can't show is the ceiling. Every running time assumes the load fits, and above 3,000 W it doesn't fit the BLUETTI at all, while the TITAN carries up to 7,200 WA1. Long and light favours the BLUETTI; big and short belongs to the TITAN.
Growth Path
Selected because: A 30,105.6 Wh ceiling and 4,000 W of solar input are how a 240 V buyer closes the storage gap over time.
solar input
The TITAN's storage gap is one you can buy your way out of. Each EF-TT-E5-G1 pack brings another 5,017.6 Wh, up to six packs and 30,105.6 WhA7, and two added packs already take it to 15,052.8 Wh, past the BLUETTI's 12,288.
Its 4,000 W of solar inputA3 is sized for that bigger bank rather than the base pack: three packs still refill in under four hours of rated sun (15,052.8 ÷ 4,000). The BLUETTI arrives already built out to 12,288 Wh behind 2,400 W of solar input, so it starts ahead on storage and behind on input.

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 TITAN 5000 is 119 lbs and the AC300 + 4×B300 367.2 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.

Keep the essentials running through a night without power
AC300 + 4×B300
Both survive the night. The AC300 + 4×B300 finishes at 16% used with 8,800Wh left — 5.3 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
Either unit
A CPAP is about 40W for eight hours, so both cover the night with room to spare and capacity decides nothing. Fan noise would — but AC300 + 4×B300 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.

Conclusion
October 4, 2026
Verdict: the TITAN 5000
Buy the TITAN 5000. It delivers 7,200 W at 120/240 V split-phaseA1 through an L14-30 twist-lockA2, more than twice the BLUETTI's 3,000 W, and the BLUETTI's record lists no 240 V output at all, so a well pump, dryer or central-air condenser on a 240 V circuit can only run from the TITAN. It also costs $2,397 less. The BLUETTI's 12,288 Wh outlasts the TITAN's 5,017.6 WhA6 by a wide margin on long, light outages, and that's the only reason to choose it: an all-120 V household that wants the most nights per charge.

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 AC300 + 4×B300 rates 3.3/5 (1st 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 AC300 + 4×B300 (367.2 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 248 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
Warranty: 5 Years vs 4
The TITAN 5000 is covered for 5 years against the AC300 + 4×B300's 4 years. An underrated factor if you're keeping this unit for years.
AC300 + 4×B300: Noise Level Not Disclosed
The TITAN 5000 publishes its noise level (39dB); the AC300 + 4×B300 doesn't publish one. That isn't evidence the AC300 + 4×B300 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 TITAN 5000's 39dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the AC300 + 4×B300 before deciding.

What happens after you buy — true cost of ownership, brand trust, and growth potential.
Lifetime value

│ 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
These are the two biggest communities in portable power, and both brands come with a support caveat. EcoFlow's support experiences are polarized, and it offers no parts or service out of warranty. BLUETTI's support is the most inconsistent in the space by our brand record, and some older models have no spare-parts policy. For hardware wired into a home panel, buy BLUETTI direct, and buy EcoFlow from a retailer with a strong return policy.

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, and they describe what the hardware is rather than how it behaves. The rating label gives 7,200 W at 120/240 V split-phase, 30 AA1, an L14-30 outlet beside three 120 V 20 A socketsA2, 4,000 W of solar inputA3 and a 5,017.6 Wh packA6 that expands to 30,105.6 WhA7. Our arithmetic on the pack voltage points to LFP cellsA12.
“7,200 W continuous output with 120/240 V split-phase at 30 A.”
BLUETTI AC300 + 4×B300
Field reports on the AC300 are mostly about living with it, and the fan comes out well. Owners and reviewers consistently describe it as audible but quiet for the size: one reviewer said you'll forget it's thereB5, and one owner heard only air moving, no motorB6. The app gets weaker marks, called basic by one reviewerB7 and stuck on loading for one ownerB8.
Two caveats from our research carry over to this stack. Most of the measured figures in the ledger come from an AC300 with a single module, not this four-module system, so its runtimes and charge times don't transferB0. And one owner's head unit died with no repair parts available from BLUETTIB9B10.
“I was immediately impressed with the unit's quality, finish, and clever design.”

Who Should Buy Which
Buy the TITAN 5000 if you…
- →Your well pump, dryer, range or central-air condenser sits on a 240 V circuit, and you want it on the backed-up list through EcoFlow's 240 V Smart Home Panel 10A1A5.
- →You need more than 3,000 W at once: the TITAN carries 7,200 WA1, enough for several heavy circuits across both legs of the panel together.
- →You'd rather refill from 4,000 W of panelsA3 than sit out an outage on stored energy alone.
- →You already have rooftop solar and want to keep it: EcoFlow says the TITAN 5000's AC coupling works with compatible existing panels through the Smart Home Panel 10 and a CT sensorA19.
Buy the AC300 + 4×B300 if you…
- →Every circuit you back up is 120 V, your outage load is a fridge, lights and a router, and you want the 5.3 extra nights the BLUETTI posted in the 8-hour blackout.
- →You want 12,288 Wh in one purchase rather than building toward it with extra packs.
If neither fits
If you want the whole house, central air included, running for days at a time, a battery this size is the wrong tool: a standby generator or a permanently installed home battery bank belongs on that list. And if all your loads are 120 V and you'd rather spend less, EcoFlow's TITAN 5000 Classic carries the same 5,017.6 Wh packA6 without the split-phase inverter.
The Bottom Line
Buy the TITAN 5000. It runs 7,200 W split-phase where the BLUETTI tops out at 3,000 W on 120 V, it reaches the 240 V circuits the BLUETTI can't touch, and it costs $2,397 less.
The BLUETTI's 12,288 Wh is the honest reason to pause, and it applies to one household: all 120 V, light loads, long outages. If that's yours, take the extra nights. If there's a two-pole breaker in your panel you'd miss in a blackout, the TITAN is the one that can keep it on.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the BLUETTI AC300 + 4×B300 run a 240 V well pump?
No. Its record lists no 240 V output, so a pump on a two-pole 240 V breaker won't run from it. The TITAN 5000 outputs 120/240 V split-phase at up to 7,200 W through an L14-30 outlet, which is what that circuit needs.
Which lasts longer in a power outage, the TITAN 5000 or the BLUETTI AC300 with four B300s?
The BLUETTI, on 120 V loads. In the engine's 8-hour blackout, a 1,645 Wh night, it finishes 16% used with 5.3 more nights left, against 39% and 1.6 nights for the TITAN. The TITAN closes that gap only with extra packs, at 5,017.6 Wh each.
How much more power does the TITAN 5000 deliver than the AC300?
It runs 7,200 W continuous against 3,000 W, more than twice as much. 240 V at 30 A is exactly 7,200 W, so the TITAN can put its whole rating on one 240 V circuit.
Does the TITAN 5000 work with a home transfer panel?
EcoFlow sells it bundled with its 240 V Smart Home Panel 10 and markets the line as whole-home backup. The label places it in a utility space rather than a bedroom or living area, so plan for a garage or utility-room install.
Is the BLUETTI AC300 + 4×B300 worth the extra money over the TITAN 5000?
Only for storage. The extra $2,397 buys 12,288 Wh against 5,017.6 Wh, but no 240 V and less than half the continuous output. If your loads are all 120 V and light, that storage is worth paying for; if they aren't, it isn't.
What does the TITAN 5000 add beyond the spec sheet?
EcoFlow sells the TITAN 5000 with a factory pre-wired Smart Home Panel 10 controlling 10 circuits from the app, and says it is UL 9540 certified and tested to UL 9540A. TITAN AC coupling works with compatible existing rooftop solar when the Smart Home Panel 10 and a CT sensor are installed. Storm Mode charges the battery before severe weather, and the unit expands from 5 kWh to 30 kWh. OASIS 3.0 is marked a subscription feature in the EcoFlow app.
