Head-to-head test
EcoFlow DELTA 3 Ultra vs EcoFlow TITAN 5000 Classic
Both stop at 120 V, so this comes down to how many nights you need covered: the Classic holds 1.6 times the energy, refills from four times the solar input and grows to six packs, which pays off the moment an outage outlasts one evening.

Spec deltas
Neither of these puts out 240 V, so they run the same kinds of loads and the real question is for how long. The TITAN 5000 Classic carries 5,017.6 Wh to the DELTA 3 Ultra's 3,072 Wh, takes 3,200 W of solar where the Ultra takes 800 W, and adds packs up to six; the Ultra is sealed at what you buyB1B3B6.
That makes the Classic our pick for a house that has to ride out more than one night. On the engine's 8-hour blackout the Ultra finishes with 966 Wh in hand, a bit over half of a second night, while the Classic finishes with 2,620 Wh, enough for 1.6 more nights like it. EcoFlow sells the Classic with its 120 V Smart Home Panel 10, so those extra hours reach the circuits in your breaker boxB4.
The Ultra's case is real, and it's mostly money. It costs $1,399 to the Classic's $2,599, puts six AC outlets and two 140 W USB-C ports on its face against the Classic's four outlets and single 60 W portB2B8, and if one evening's outage is the whole job, 3,072 Wh does it with room to spare.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
solar input
The refill math widens that gap instead of closing it. Replacing the night's 1,645 Wh takes the Ultra's 800 W input about two hours of full-rated sun and the Classic's 3,200 W input about half an hour. Give both a grey day with a couple of good hours and the Ultra falls just short of putting one night back, while the Classic refills completely with sun to spare.
DELTA 3 Ultra: 3,072Wh, 800W max solar inputTITAN 5000 Classic: 5,017.6Wh, 3,200W max solar inputB3B58-Hour Blackout (1,645Wh): Ultra ends with 966Wh left, Classic with 2,620Wh
Why it mattersIf your outages run longer than a night, or panels will be doing the recharging, buy the Classic.
continuous output
So the Classic doesn't unlock new appliances. A well pump or an electric dryer stays dark on either one. What the extra money buys is duration, delivered to your 120 V circuits through a panel EcoFlow sells for exactly that jobB4. That's a fine thing to buy, as long as you know it's the thing you're buying.
TITAN 5000 Classic: 4,000W continuous at 120V only, no 240V split-phaseB1DELTA 3 Ultra: 3,600W continuous, no 240V outlet on recordEcoFlow bundles the Classic with its 120V Smart Home Panel 10B4
Why it mattersAnyone hoping the bigger box would run 240 V loads should be looking at the TITAN 5000, not the Classic.
Capacity
Add one extra pack and the Classic doubles its nameplate, comfortably past that day even after the same 85% allowance. The Ultra's ceiling is the box it came in. The Classic's is nearly ten times the Ultra's, so a household whose must-run list keeps growing adds a pack instead of starting over.
DELTA 3 Ultra: sealed at 3,072Wh, no expansion portTITAN 5000 Classic: expands to 30,105.6Wh, six packs of 5,017.6WhB6Van Life Daily (4,685Wh): Ultra 2,074Wh short, Classic 420Wh short
Why it mattersIf your daily use is heading past what 3,072 Wh can hold, start on the Classic; the Ultra can't follow you there.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: The Classic's extra 1,945.6 Wh (5,017.6 against 3,072) and its 3,200 W solar input decide how many outage nights each unit covers and how fast it recovers.
continuous output
Night one is never the hard part; both units get through it. Day three is, when the question becomes how much each box can put back between sunrise and dark. The Classic's 30–250 V input takes up to 3,200 WB3, four times the Ultra's 800 W, and at full rating that refills its whole 5,017.6 Wh in about an hour and a half, where the Ultra needs about four hours for its 3,072 Wh.
The catch sits on the roof, not in the box. A 3,200 W input only pays off if you buy 3,200 W of panels to feed it, and that's a rooftop-scale purchase on top of $2,599. If your solar plan is a couple of folding panels, the Classic's input mostly idles and the runtime gap shrinks back to the capacity gap.
Growth Path
Selected because: Only the Classic adds capacity, up to six packs and 30,105.6 Wh; the Ultra stops at 3,072 Wh.
solar input
The Ultra is a finished product: no expansion port, so 3,072 Wh is its number for life. That's no flaw for the one-night buyer. It's a wall for anyone whose list of must-run loads is still getting longer.
The Classic starts higher, at 5,017.6 Wh, and takes extra packs that each match it, up to sixB6. Nobody needs 30,105.6 Wh on day one. The point is that the second pack is an add-on rather than a replacement, which is the difference between upgrading and selling the first unit.
Your Life, Your Pick
Selected because: Both units are 120 V only, so every scenario row here comes down to capacity rather than capability.
Every row the Classic takes here, it takes by margin. The Ultra passes the weekend, the workday, the tailgate and the blackout too; it just finishes each with less in hand. That's the shape of the whole page: the Classic runs the same 120 V loads as the Ultra, for longer.
The one row neither clears is the heaviest daily profile, 4,685 Wh. The Classic's nameplate would cover it, but the flat 85% usable allowance leaves it 420 Wh under, against 2,074 Wh for the Ultra. Treat that row as the line where one pack stops being enough, and notice which of the two can add a second.

The TITAN 5000 Classic at 102.5 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 Classic's problem here; getting to a campsite was.

A CPAP is about 40W for eight hours, so both cover the night many times over and the capacity margin is a formality.

Conclusion
October 4, 2026
Verdict: the TITAN 5000 Classic, on Power Score margin
Buy the Classic if your backup has to last past one night or you plan to run real solar into it. It holds 5,017.6 Wh against the Ultra's 3,072 Wh, ends the engine's 8-hour blackout with 2,620 Wh still in it against the Ultra's 966 Wh, accepts up to 3,200 W of panels against 800 WB3, and grows to 30,105.6 WhB6. What it doesn't do is add 240 VB1, so don't pay $1,200 more expecting a well pump or a dryer to come back on. If one evening of 120 V loads is the whole plan, the Ultra covers it for less.

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, DELTA 3 Ultra rates 4.7/5 (84th percentile of 26 Large-class units), and TITAN 5000 Classic rates 3.8/5 (32nd 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 DELTA 3 Ultra (72.1 lbs) is manageable solo but heavier than a large checked suitcase. The TITAN 5000 Classic (102.5 lbs) is firmly a two-person lift. It goes where you put it and stays there. That's a 30 lb difference.
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 Classic 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.
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 Classic 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. 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 Classic's 1.9, but that spread is the price gap, not the terms.
Full record above — the Test Desk pick is the TITAN 5000 Classic.

Analyst note
The TITAN 5000 Classic 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.

Analyst note
The DELTA 3 Ultra is sealed at 3,072Wh, which is fine if that covers you. The TITAN 5000 Classic 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.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Ultra
Most of the field record for the Ultra comes from reviews of the DELTA 3 Ultra Plus, a sibling with the same capacity, output and chassis, so read it as character rather than proof for the base modelA0. One reviewer worked an eight-hour remote day on it, laptop, desktop workstation and monitors, and finished with 40% leftA8. Another pulled 300 to 600 W from a single outlet for a GPU benchmark and got a little over 4.5 hoursA7; divide the Ultra's 2,611 Wh usable figure by 4.5 hours and you get about 580 W, right inside that range.
“Even when you're pushing it hard, the DELTA 3 Ultra Plus runs much quieter than older EcoFlow models, like the DELTA 2 Max.”

EcoFlow TITAN 5000 Classic
Everything on record for the Classic is EcoFlow's own documentation and our reading of it, not field useB0. The rating label sets the pack at 5,017.6 WhB5, the inverter at 4,000 W on 120 V onlyB1, the solar input at 30–250 V and up to 3,200 WB3, and the ceiling at six packs, 30,105.6 WhB6. Those ratings are what this side of the page argues from.

Who Should Buy Which
Buy the DELTA 3 Ultra if you…
- →The household whose outage plan is one night of fridge, router, lights and phones: the Ultra gets through the 8-hour blackout with margin, and you keep $1,200.
- →The desk that runs two laptops off the battery: two 140 W USB-C ports against the Classic's single 60 W portB8.
- →Anyone whose solar setup will never be more than about 800 W of panels, where the Classic's 3,200 W input would sit idle.
Buy the TITAN 5000 Classic if you…
- →The house that wants backup on its 120 V circuits through EcoFlow's 120 V Smart Home Panel 10B4, and needs it to last beyond one night.
- →The rooftop-solar owner with a string that can actually feed 3,200 W across a 30–250 V windowB3.
- →Anyone who expects the must-run list to grow: matching packs take the Classic to 30,105.6 WhB6, and the Ultra can't add any.
- →A home that already has rooftop solar it wants to keep, or whose permit or insurer asks for UL 9540: the Classic is listed as certifiedB14 and can AC couple to compatible existing panelsB18.
If neither fits
If a well pump, electric dryer or central air on a 240 V circuit has to run in an outage, close this tab: neither unit has 240 VB1, and the TITAN 5000 is the split-phase one. And if the job is a CPAP and some phones, both are oversized; a 320 Wh night is work for a 1 kWh-class portable.
The Bottom Line
Both of these stop at 120 V, so what $1,200 buys with the Classic is time: 1.6 times the energy, four times the solar input, and packs you can add when the list grows. In an outage that rolls into a second and third day, that's the difference between topping up every afternoon and counting watt-hours.
If one night is the plan, the Ultra does it and you keep the difference. If it isn't, buy the Classic.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the EcoFlow TITAN 5000 Classic run 240V appliances?
No. The Classic's rating label gives it 4,000 W at 120 V only, with no split-phase output, and the DELTA 3 Ultra has no 240 V outlet either. For a well pump, dryer or central air on a 240 V circuit, you need the TITAN 5000 or another split-phase unit.
How much longer does the TITAN 5000 Classic last than the DELTA 3 Ultra in a blackout?
About 1.6 times as long on the same load, because that's how much more battery it has: 5,017.6 Wh against 3,072 Wh. On the engine's 8-hour blackout profile the Ultra ends at 63% used and the Classic at 39%, so the Classic still has more than one and a half further nights in hand while the Ultra has a bit over half of one.
Can you add an extra battery to the DELTA 3 Ultra?
No. The base DELTA 3 Ultra is sealed at 3,072 Wh with no expansion port. The TITAN 5000 Classic takes EcoFlow's EF-TT-E5-G1 extra battery, each one matching its own 5,017.6 Wh, up to six packs and 30,105.6 Wh in total.
Is the TITAN 5000 Classic worth the extra money over the DELTA 3 Ultra?
It is if your outages run past a night or you'll feed it serious solar. The extra $1,200 buys 1,945.6 Wh more battery (5,017.6 Wh against 3,072 Wh), four times the solar input and room to grow; it does not buy 240 V or new kinds of loads. If one evening of 120 V loads is the whole job, the Ultra does it for $1,399.
Where does the TITAN 5000 Classic go in the house?
Its rating label places it in a utility space, outside bedrooms and other living areas. EcoFlow pairs it with its 120 V Smart Home Panel 10, so plan on it as part of the house wiring rather than something you set on the kitchen counter during a storm.
What does the TITAN 5000 Classic add beyond the spec sheet?
EcoFlow lists the TITAN 5000 Classic as UL 9540 certified and tested to UL 9540A. The TITAN 5000 Classic ships with a factory pre-wired Smart Home Panel 10 that controls 10 circuits from the app. Storm Mode charges the battery ahead of severe weather. The TITAN 5000 Classic can AC couple with compatible existing rooftop solar, which needs the Smart Home Panel 10 and a CT sensor.
