EcoFlow TITAN 5000 vs BLUETTI AC500 + 2×B300K

The TITAN 5000 runs your 240 V circuits and the AC500 stack can't, so the stack's one real comeback, 512.4Wh more battery, is a consolation prize rather than a counterweight.

The TITAN 5000 puts 7,200W on a 120/240 V split-phase outletA1; the AC500 + 2×B300K stops at 5,000W on 120 V. That line settles the page for anyone with a well pump, an electric dryer or central air, because the BLUETTI has no way to reach a 240 V breaker however much battery sits behind it.

The unusual part is the price. The machine with more output, split-phase and a bigger solar input is the cheaper of the two here, by $749. Split-phase is usually the thing you pay extra for. This time the stack charges more and leaves it out.

The BLUETTI's real counter is capacity, 5,530Wh to the TITAN's 5,017.6WhA6, plus two 100W USB-C ports to one 60WA9. That's worth something on the desk side of a home office. It isn't worth giving up the 240 V half of your house.

What the Numbers Reveal

Each conclusion stated first — the numbers behind it on one line, the full analysis below.

F1

continuous output

Wired through a 240 V transfer panel, which is how EcoFlow sells itA5, the TITAN keeps a well pump or a central-air condenser in the plan. The stack, at any battery size, keeps the 120 V circuits and leaves every double breaker dark. A 240 V load is a yes-or-no question, and the stack's answer is no.

TITAN 5000: 7,200W, 120/240 V split-phase at 30AA1Outlets: three 120V 20A sockets plus one L14-30 twist-lock marked 120V/240V 30AA2AC500 + 2×B300K record: no 240 V outputSold bundled with EcoFlow's 240 V Smart Home Panel 10 as whole-home backupA5

Why it mattersIf one load on your must-run list sits on a double breaker, stop comparing: it's the TITAN.

F2

No house runs flat out for long; a well pump cycles and a condenser rests. But the stack's extra 436 usable Wh buys only minutes at that kind of draw, while each TITAN pack adds 5,017.6WhA7. If heavy 240 V loads are why you're buying, a second pack is the real capacity plan, and the cheaper base unit leaves room for it.

TITAN 5000: 7,200W continuousA1Usable after the flat 15% derate: TITAN 4,265Wh, stack 4,701WhExpandable in matching 5,017.6Wh packs to 30,105.6WhA7AC500 + 2×B300K: 5,000W continuous

Why it mattersHeavy-load households should weigh the TITAN's expansion path, not the stack's head start in capacity.

F3

solar input

Real sun never holds the ceiling, so the ratio is what survives: the TITAN takes a third more solar into a smaller pack. In a multi-day outage that means more of each sunny day spent full instead of filling, and the gap widens as you add packs for the same panels to feed.

TITAN 5000 solar: 40–450V, 4,000W maxA3AC500 + 2×B300K solar: 3,000W maxPack sizes: 5,017.6Wh vs 5,530WhEcoFlow's product image shows the display at 4.00 kW inA4

Why it mattersAnyone planning a big rooftop or ground array for long outages gets more out of every panel on the TITAN.

The specific dimensions that decide these two units — everything else is a tie.

Runtime: Will It Power Your Gear?

Selected because: The TITAN's 7,200W split-phase output against the stack's 5,000W on 120 V decides more here than the 512.4Wh capacity gap.

continuous output

The output gap is bigger than the capacity gap, and it runs the TITAN's way. 7,200W against 5,000W is 2,200W of extra headroom, delivered across two 120 V legs or at 240 V through the L14-30A2. The stack's extra battery, 512.4Wh on paper and 436Wh after the flat 15% derate, is about a tenth of either pack.

In the profiles we run, that tenth barely registers: the 8-hour blackout takes 39% of the TITAN's usable battery and 35% of the stack's, so both have a full second night in reserve. The 240 V circuit the stack can't feed doesn't get a first night.

Growth Path

Selected because: The TITAN takes 4,000W of solar to the stack's 3,000W and grows in 5,017.6Wh packs to 30,105.6Wh.

solar input

Both expand, but the TITAN grows with more behind it: matching 5,017.6Wh packs to a ceiling of six and 30,105.6WhA7, fed by a 4,000W solar input that accepts strings up to 450VA3. The stack adds BLUETTI batteries behind a 3,000W solar ceiling, so on any array bigger than that, every pack it gains fills more slowly than a TITAN pack would.

One honest catch on the TITAN's side. EcoFlow's label sites it in a utility spaceA10 and rates charging only from 32°F upA11. In an unheated garage in January it can still run the house, but it won't refill until it warms, so pick a spot that stays above freezing.

Brand Trust

Selected because: The TITAN's evidence is its maker's label and the stack's is a handful of single-battery reports, so where you buy matters.

This is a choice between two imperfect support records. EcoFlow's file shows polarized experiences with a US phone line, and no parts or service once the warranty runs out; BLUETTI's shows the least consistent support in the category, mostly by email across time zones. Neither file picks a side for you. Both argue for a retailer with a clean return policy.

On the stack itself, the reports are thin and cover the AC500 with one B300KB0. One owner had to chase support for a battery cable left out of the boxB6, and a reviewer's inverter stayed dark while its battery powered onB7. If you go BLUETTI, test the whole stack the week it lands.

Will It Power Your Gear?

Scenario math and per-appliance runtimes, modeled from the spec record.

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 TITAN 5000 is 119 lbs and the AC500 + 2×B300K 196.1 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.

8-Hour Blackout

Keep the essentials running through a night without power

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 AC500 + 2×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 — 100W on the AC500 + 2×B300K against 60W — which beats the inverter for convenience and wastes less energy.

Tailgate Party

Game day power for the crew

Neither unit

Scoring these two at a tailgate is a category error: neither travels — the TITAN 5000 is 119 lbs and the AC500 + 2×B300K 196.1 lbs, and at those weights they roll off a truck bed if they go anywhere at all.

Van Life Daily

A full day of mobile living — the ultimate endurance test

AC500 + 2×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 AC500 + 2×B300K covers it with only 16Wh left — well under half a percent of what the day asks, so it finishes with nothing behind it.

Conclusion

October 4, 2026

Verdict: the TITAN 5000

Buy the TITAN 5000. It's the only one of the two with 120/240 V split-phase output, through an L14-30 outlet rated 30AA1A2; it carries 7,200W against the stack's 5,000W, takes 4,000W of solar against 3,000WA3, and costs $3,199 to the BLUETTI's $3,948. The AC500 + 2×B300K answers with 512.4Wh more battery and stronger USB-C, a fair trade only for an all-120 V home that will never wire in a 240 V load.

Today the AC500 + 2×B300K is $3,299, $649 under its typical $3,948. The verdict weighs typical prices, not today's. Prices checked 28 days ago.

EcoFlow has not published this price yet. We priced the TITAN 5000 at $3,199 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.

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 AC500 + 2×B300K rates 4.1/5 (47th percentile of 20 Home Backup-class units).

Test Notes & Caveats

Hidden gotchas and advantages we spotted that you won't find on the product page.

[CAUTION]

Weight Reality Check

Neither unit is grab-and-go. The TITAN 5000 (119 lbs) is a two-person lift. The AC500 + 2×B300K (196.1 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 77 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.

[NOTE]

Warranty: 5 Years vs 4

The TITAN 5000 is covered for 5 years against the AC500 + 2×B300K's 4 years. An underrated factor if you're keeping this unit for years.

[NOTE]

AC500 + 2×B300K: Noise Level Not Disclosed

The TITAN 5000 publishes its noise level (39dB); the AC500 + 2×B300K doesn't publish one. That isn't evidence the AC500 + 2×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 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 AC500 + 2×B300K before deciding.

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.

All EcoFlow power stations tested →

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.

All BLUETTI power stations tested →

Analyst note

A support line you can phone against one that mostly answers by email. EcoFlow's record is polarized and stops at the warranty, with no parts or service after it; BLUETTI's is the least consistent in the category and runs smoother when you buy direct. Neither should decide this page, but on a system you wire into the house, get the retailer's return policy in writing.

Growth path

TITAN 5000

EXPANDABLE

Supports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 5,018Wh.

Accepts up to 4,000W of solar. Enough for a serious multi-panel array.

Adequate ports for most setups, but heavy users may want a power strip.

What Owners Report

Patterns from published owner reports and long-term reviews — every claim cited to its source below.

EcoFlow TITAN 5000

The TITAN 5000's side rests on EcoFlow's own published ratings, not field reports. The label sets the output at 7,200W on 120/240 V split-phase at 30AA1, the pack at 5,017.6WhA6 and the solar input at 4,000W across 40–450VA3, and EcoFlow's product image shows the display at 4.00 kW in and 7.20 kW outA4. Its AC IN/OUT port can also pass up to 7,200W straight through from a 240 V feedA14.

Day to day it reads well: one owner found it quieter than a smaller PecronB1, another reports near-flawless running from day oneB12, and a reviewer calls the app decent for the basicsB9.

The rough edges are specific. One owner measured about 35W more draw than the actual load when it switched to grid powerB3, and found it has to be disconnected before it will fully shut downB4. A reviewer warns that the indicator lights stay bright all the time, which rules out a bedroomB11.

“So far pretty darn happy, and it's much quieter than the small Pecron E1500LFP I have.”

Who Should Buy Which

Buy the TITAN 5000 if you…

  • →A house with a well pump, electric dryer or central air on a 240 V breaker that has to stay on through an outage: only the TITAN reaches itA1.
  • →Someone wiring backup through EcoFlow's 240 V Smart Home Panel 10, the way the TITAN is soldA5.
  • →An off-grid or long-outage plan built on a big array: 4,000W of solar input against 3,000WA3.
  • →A time-of-use-rate home that wants peak hours handled automatically: EcoFlow lists X-Fusion 2.0 for the TITAN 5000A23, and OASIS 3.0 adds off-peak charging as a subscription feature in the EcoFlow appA17.

Buy the AC500 + 2×B300K if you…

  • →An all-120 V home that will never back up a double-breaker load and wants the extra 512.4Wh on day one.
  • →An RV owner who wants to plug a 30A RV cord straight into the box: the stack has an RV-style 30A outlet and the TITAN does not.
  • →A home office running laptops directly off the unit: two 100W USB-C ports against one 60WA9.

If neither fits

A household that just wants the fridge, the router and a few lights through a night. Both of these are panel-scale systems; a mid-size portable power station covers that job without a utility-room install.

08

The Bottom Line

Buy the TITAN 5000. It's the one that reaches your 240 V circuits, it has 2,200W more output and a third more solar input, and it costs $749 less. The stack's extra 512.4Wh would have to outweigh all of that, and for a house with even one double-breaker load it can't.

Frequently Asked Questions

Answers drawn from the spec record and cited owner research.

Does the BLUETTI AC500 support 240V?

Not the AC500 + 2×B300K covered here: our record lists no 240 V output for it, so it runs 120 V circuits only. The TITAN 5000 delivers 120/240 V split-phase at 30A through an L14-30 outlet, which is what a well pump, dryer or central air on a double breaker needs.

TITAN 5000 vs AC500: which charges faster from solar?

The TITAN 5000. It accepts up to 4,000W of solar across 40–450V, against 3,000W for the AC500 stack. At those ceilings the TITAN refills its 5,017.6Wh pack in about an hour and a quarter of perfect sun, while the stack's 5,530Wh takes just under two hours.

How much battery does the TITAN 5000 have compared with the AC500 + 2×B300K?

Less, by 512.4Wh: the TITAN 5000 holds 5,017.6Wh and the AC500 stack 5,530Wh across its two B300K batteries. Both expand, the TITAN in matching packs up to six and 30,105.6Wh, the AC500 with more BLUETTI batteries.

Can the TITAN 5000 back up a whole house?

It can back up the circuits you choose, 240 V ones included, and EcoFlow sells it that way, bundled with its 240 V Smart Home Panel 10 as whole-home backup. The base 5,017.6Wh pack goes quickly under heavy load, so a whole-house plan usually means adding packs, up to 30,105.6Wh.

What does the TITAN 5000 add beyond the spec sheet?

EcoFlow lists X-Fusion 2.0 for the TITAN 5000: solar powers the home first, the battery covers peak-rate hours, and working with the grid through the main panel it can power loads beyond the backed-up circuits. Storm Mode also charges the battery before severe weather. It is UL 9540 certified and tested to UL 9540A, and EcoFlow's OASIS 3.0 forecasts solar 3 days ahead and charges off-peak, but the store marks it a subscription feature in the EcoFlow app.
