EcoFlow DELTA 3 Ultra vs EcoFlow TITAN 5000

The TITAN 5000 puts 120/240 V split-phase on an L14-30 twist-lock and the Ultra has no 240 V output at all, so whether anything on a 240 V breaker has to run in an outage settles this before capacity even comes up.

The TITAN 5000 does something the DELTA 3 Ultra can't do at any price: it puts out 120/240 V split-phase, 7,200 W of it, through an L14-30 twist-lock beside three 120 V 20 A socketsB1B2. The Ultra tops out at 3,600 W, all of it on 120 V.

So this page turns on a breaker-panel question. If a well pump, an electric dryer or anything else on a double-pole breaker has to keep running in an outage, the Ultra isn't the smaller option, it's no option, and the TITAN 5000 is our pick. Its bigger pack and faster solar refill are real, but they're the supporting cast.

If nothing you care about runs on 240 V, the logic flips. The twist-lock sits idle, the extra $1,800 buys margin rather than capability, and the Ultra at $1,399 is the sensible box, or the 120 V Classic if one night won't be enough.

02

What the Numbers Reveal

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

F1

continuous output

That's the line between powering appliances and powering circuits. Through EcoFlow's 240 V Smart Home Panel 10B5, the TITAN 5000 can reach the double-pole breakers a house puts its heaviest loads on. The Ultra can't reach them at all, however much battery it has left.

TITAN 5000: 7,200W continuous, 120/240V split-phase at 30AB1TITAN 5000: one L14-30 twist-lock marked 120V/240V 30AB2DELTA 3 Ultra: 3,600W continuous, no 240V outlet on record

Why it mattersIf a 240 V circuit is on your must-run list, take the Ultra off the shortlist.

F2

solar input

The 450 V ceiling says what kind of array it expects: a long rooftop string, and EcoFlow sells the unit bundled with panelsB5. Paired with one, a long outage stops being a countdown and becomes a daily cycle. The Ultra's 800 W can keep pace with a fridge-and-lights night; it was never sized to refill a house.

TITAN 5000 solar: 40–450V, up to 4,000WB3DELTA 3 Ultra solar: up to 800WPacks: 5,017.6WhB6 against 3,072Wh

Why it mattersRooftop-solar households should weigh this second only to the 240 V question.

F3

In a 120 V-only home, the TITAN 5000's headline feature is a socket nothing plugs into. You'd be paying $1,800 for split-phase you never touch, while the cheaper box has the more useful face.

DELTA 3 Ultra: six AC outlets, two USB-C ports at 140WTITAN 5000: three 120V 20A sockets, one L14-30, one 60W USB-CB2B98-Hour Blackout (1,645Wh): Ultra ends at 63% used

Why it mattersGas dryer, city water, nothing on a double-pole breaker you need? The Ultra is the better buy.

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

Your Life, Your Pick

Selected because: Every scenario here is a 120 V load, the Ultra's whole territory, so the table measures margin; the 240 V circuit that decides this page sits outside it.

This table understates the matchup, and it's worth knowing why. Every profile is a 120 V load, from a 40 W CPAP to a 400 W tailgate peak, and the Ultra passes every one except the heaviest daily draw. Where the TITAN 5000 wins a row, it wins on what's left over, not on whether the job gets done.

The decisive load isn't in the table. A well pump or an electric dryer runs on a 240 V breaker, and the Ultra has no 240 V output to offer it, while the TITAN 5000's L14-30 carries split-phaseB2. If one of those circuits is on your list, read the percentages for interest only; the Ultra was out before the first row.

Runtime: Will It Power Your Gear?

Selected because: Five times the solar input into 1.6 times the battery changes what a multi-day outage looks like on the TITAN 5000.

continuous output

Refill is where the TITAN 5000's numbers stack. Its 40–450 V input takes up to 4,000 WB3, five times the Ultra's 800 W, so the pack that's 1.6 times larger still comes back sooner in absolute hours.

One caveat on our own pick, straight off its label: it charges only between 0 °C and 45 °CB11, the floor you'd expect from the LFP cells its pack voltage points toB12. The label also wants it in a utility spaceB10. If that space is an unheated garage in a northern winter, the panels can be producing and the pack still won't take a charge until the room climbs past 32 °F.

Growth Path

Selected because: The TITAN 5000 adds packs up to 30,105.6 Wh, and 240 V loads are the ones that need them; the Ultra's 3,072 Wh is final.

solar input

The Ultra's 3,072 Wh is the last capacity figure it will ever have. The TITAN 5000 adds identical 5,017.6 Wh packs up to six, 30,105.6 WhB7, and EcoFlow sells it bundled with that extra battery and the 240 V Smart Home Panel 10 under a whole-home backup bannerB5.

That pairing is the tell. Split-phase loads are the heavy ones, and heavy loads are what empty packs, so a 240 V house that sizes for one pack today is a likely customer for a second. The TITAN 5000 makes that an add-on; the Ultra never had the option.

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

DELTA 3 Ultra

The TITAN 5000 at 119 lbs is not a take-along — it rolls off a truck bed if it travels at all, so this scenario belongs to the DELTA 3 Ultra by default — and it earns it, covering the 2,100Wh with 511Wh to spare. Capacity was never the TITAN 5000's problem here; getting to a campsite was.

8-Hour Blackout

Keep the essentials running through a night without power

TITAN 5000

Both survive the night. The TITAN 5000 finishes at 39% used with 2,620Wh left — 1.6 more nights like it. The DELTA 3 Ultra finishes at 63% with 966Wh, 59% of a second night. If your outages tend to run past one evening, that difference is the whole argument between them.

SCN-03 · 8 hours · needs 320Wh

CPAP Overnight

Sleep therapy without interruption — the #1 medical use case

DELTA 3 Ultra

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 DELTA 3 Ultra is rated 30dB against the TITAN 5000's 39dB. 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.

TITAN 5000

The TITAN 5000 clears the workday at 21% used, banking 3,355Wh — late work, extra calls, or a second laptop charge without arithmetic. The DELTA 3 Ultra at 35% also finishes, with 1,701Wh of slack for the unplanned.

DELTA 3 Ultra

The TITAN 5000 at 119 lbs is not a take-along — it rolls off a truck bed if it travels at all, so this scenario belongs to the DELTA 3 Ultra by default — and it earns it, covering the 670Wh with 1,941Wh to spare. Capacity was never the TITAN 5000's problem here; getting to a tailgate was.

Van Life Daily

A full day of mobile living — the ultimate endurance test

Neither unit

Neither unit covers this scenario's 4,685Wh: the DELTA 3 Ultra comes up 2,074Wh short (about 56% covered), the TITAN 5000 420Wh (91%) (its nameplate 5,018Wh actually clears this — the flat 15% conversion allowance is what tips it under). Either gets you most of the way, so this is a scenario you plan around rather than one you should rule them out for.

Conclusion

October 4, 2026

Verdict: the TITAN 5000, on Power Score margin

Buy the TITAN 5000 if any 240 V circuit has to stay live when the grid drops. Split-phase output at 30 AB1 is something the Ultra lacks outright, and it arrives with twice the continuous output (7,200 W against 3,600 W), 1.6 times the battery, five times the solar inputB3 and a ceiling of 30,105.6 WhB7. If every load you need plugs into a 120 V socket and one night covers you, the Ultra does that for $1,800 less, and the TITAN's twist-lock would just sit there.

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.

Owner claims

Statements about owner experience are cited to published reviews — see Sources & Research Notes below.

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, DELTA 3 Ultra rates 4.7/5 (84th percentile of 26 Large-class units), and TITAN 5000 rates 4.6/5 (79th 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 DELTA 3 Ultra (72.1 lbs) is manageable solo but heavier than a large checked suitcase. The TITAN 5000 (119 lbs) is firmly a two-person lift. It goes where you put it and stays there. That's a 47 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.

[NOTE]

DELTA 3 Ultra: Fixed Capacity

The DELTA 3 Ultra is sealed at 3,072Wh — fine if that covers you, but it's the ceiling. By contrast the TITAN 5000 can add expansion batteries, though the first thing it has over the DELTA 3 Ultra is its own 5,018Wh base — expansion is the step after that, for the buyer who would outgrow 5,018Wh as well.

[NOTE]

UPS Switchover: ≤10ms vs ≤20ms

Both list a UPS mode, at different rated speeds. The DELTA 3 Ultra 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.

[NOTE]

Warranty: No Difference

Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. Worth saying because the per-dollar framing can suggest otherwise: the DELTA 3 Ultra works out at 3.6 years of cover per $1,000 spent against the TITAN 5000's 1.6, but that spread is the price gap, not the terms.

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.

Growth path

DELTA 3 Ultra

FIXED CAPACITY

Fixed at 3,072Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.

Accepts up to 800W of solar. Suitable for a 1-2 panel setup.

Generous port selection supports complex multi-device setups.

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.

Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.

DELTA 3 UltraTITAN 5000

Analyst note

The DELTA 3 Ultra is sealed at 3,072Wh, which is fine if that covers you. The TITAN 5000 starts at 5,018Wh and can grow beyond it with EcoFlow expansion batteries — real headroom the DELTA 3 Ultra doesn't have if your needs climb toward partial-home backup.

EcoFlow DELTA 3 Ultra

Reviewers describe the Ultra's switchover as seamless: one compared it to an APC unit cutting in the instant the power dropsA5, and another saw no shut-offs or dips when pulling the wall plugA6. The fans get similar praise, quieter than older EcoFlow models even with the inverter pushed to its maximumA1A2. The caveat is provenance: almost all of this was written about the DELTA 3 Ultra Plus, which shares the base model's capacity, output and chassis, so it describes the Ultra's character rather than measuring itA0.

Who Should Buy Which

Buy the DELTA 3 Ultra if you…

  • →The home on city water with a gas dryer and window AC, where nothing on a 240 V breaker matters in an outage and one night of 120 V loads is the job.
  • →The workspace that wants plenty of sockets on the box: six AC outlets and two 140 W USB-C ports, against the TITAN 5000's three 120 V sockets and one 60 W portB2B9.
  • →Anyone keeping solar to a few portable panels, well inside the Ultra's 800 W input.

Buy the TITAN 5000 if you…

  • →The house on a well: the pump lives on a 240 V breaker, and the TITAN 5000 is the only one of these two with split-phase output to reach itB1.
  • →The household wiring backup through EcoFlow's 240 V Smart Home Panel 10 so the dryer, the range or other double-pole circuits stay in playB5.
  • →The rooftop-solar owner with a high-voltage string, up to 450 V and 4,000 WB3, who wants a long outage to become a daily cycle.
  • →The homeowner who already has rooftop solar and wants to keep it: EcoFlow says the TITAN Series AC-couples with compatible existing panels, using the Smart Home Panel 10 and a CT sensorB19.

If neither fits

If the goal is a whole house running as though nothing happened, central air included, through a multi-day outage, one 5,017.6 Wh pack is a starting point rather than an answer. Price the TITAN 5000 with extra batteriesB7 against a standby generator before you buy either of these.

08

The Bottom Line

This one is settled at the breaker panel. The TITAN 5000 has 120/240 V split-phase and the Ultra has none, so if a well pump, a dryer or any double-pole circuit has to stay on through an outage, the TITAN 5000 is the only candidate on the page, and its bigger pack and faster solar refill come along for the ride.

If every load you care about is 120 V, keep the $1,800; the Ultra does the job. If even one of them isn't, buy the TITAN 5000.

Frequently Asked Questions

Answers drawn from the spec record and cited owner research.

Does the EcoFlow DELTA 3 Ultra have a 240V output?

No. Our record lists no 240 V outlet on the DELTA 3 Ultra, and its 3,600 W runs through 120 V sockets. The TITAN 5000 puts out 120/240 V split-phase at 30 A through an L14-30 twist-lock, and that is the deciding difference between these two.

What plugs into the TITAN 5000's L14-30 outlet?

The L14-30 is a four-prong twist-lock marked 120V/240V 30A, the same style many generator inlets and transfer switches use. At 240 V and 30 A it can carry the full 7,200 W, and EcoFlow's route into the house wiring is its 240 V Smart Home Panel 10.

How fast does the TITAN 5000 recharge from solar compared with the DELTA 3 Ultra?

Five times faster at full rated input: up to 4,000 W across 40–450 V against the Ultra's 800 W. That refills the TITAN's 5,017.6 Wh in about an hour and a quarter of full-rated sun and the Ultra's 3,072 Wh in about four. Real panels rarely hit their rating, so treat both as best cases.

Can the TITAN 5000 charge in a cold garage?

Not below freezing. Its rating label gives a charging range of 0 °C to 45 °C (32 °F to 113 °F), while it will discharge down to −10 °C (14 °F). If its utility space drops below 32 °F in winter, it keeps powering the house but won't refill until the room warms up.

Is the TITAN 5000 overkill if I don't need 240V?

Mostly, yes. Without a 240 V circuit to feed, its split-phase output idles and the extra $1,800 buys margin: 1.6 times the battery and five times the solar. If you need that runtime on 120 V, EcoFlow's Classic is the TITAN built for that house; if one night is enough, the Ultra covers it.

What does the TITAN 5000 add beyond the spec sheet?

EcoFlow lists it as UL 9540 certified and tested to UL 9540A, which is the paperwork a permit office or insurer may ask a home battery for. It is sold with a factory pre-wired Smart Home Panel 10 that controls 10 circuits from the app, and its X-Fusion 2.0 mode sends solar to the house first and runs the home from the battery at peak rates. OASIS 3.0 scheduling and its 3-day solar forecast are marked as a subscription feature in the EcoFlow app.
