EcoFlow DELTA Pro Ultra X vs EcoFlow TITAN 5000 Plus
Take away the solar and grid power flowing in and the Plus is a 7,200 W battery, so the big 240 V circuit its 41.7 A outlet promises only stays fully fed through a night-time blackout on the Ultra X.

Spec deltas
The TITAN 5000 Plus's rating label says 10 kW, then notes in parentheses that 7,200 W of it is for discharge onlyB1. The rest needs solar or grid power flowing in at the same time. On battery, which is the reason anyone buys one, the Plus delivers the same 7,200 W as the TITAN 5000B1, against the DELTA Pro Ultra X's 12,000 WA1.
That changes what its signature outlet means. The four-pin 14-50-pattern socket is rated 41.7 A at 120/240 VB2B3, roughly a 10,000 W circuit (41.7 × 240). With the grid up, the Plus can pass that through. With the grid down, its inverter caps the circuit at 30 A (7,200 ÷ 240), and the Ultra X has 12,000 W to give it.
So the Ultra X takes this page, by a moderate margin. The Plus has a genuine trick, an 8 kW charging path from a 240 V feedB5B15, and it costs $4,300 less. But per watt-hour of battery the Ultra X is the cheaper of the two, and it's the one that does with the grid down what the Plus's faceplate implies.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
The Ultra X's 12,000 W from battery covers the full 10,000 W that circuit is rated for, with room left over for the 120 V side of the house. The capability the Plus shows off with the grid up is the capability the Ultra X keeps with the grid down.
Plus label: 10 kW max total, 7,200 W for discharge onlyB1Plus outlet: four-pin 14-50-pattern, 120/240 V 41.7 AB3Ultra X: 12,000 W continuous at 120/240 VA1
Why it mattersIf a big 240 V load has to run during an outage, the Ultra X is the one that runs it at full size.
solar input
In a blackout that feed is gone unless you supply your own 240 V source. Without one, the Plus refills from the sun at up to 8,000 W across its two inputs, or from a 120 V wall inlet that's as dead as the grid. The Ultra X takes up to 10,000 W of solar.
Plus display shows 8.00 kW inB5AC IN/OUT port: up to 7,660 W charge-only from a 120/240 V split-phase sourceB15Plus solar: 8,000 W on 2 inputsB4; wall inlet: 100–120 V, 15 AB9Ultra X solar: up to 10,000 WA3
Why it mattersThe fast charge is worth paying for only if you own a 240 V source you'll run in an outage; otherwise judge the Plus by its 8,000 W of solar.
Capacity
What the Plus adds over the TITAN 5000 is grid-side: the 41.7 A rating and the 8 kW charge pathB2B5, not more battery or more inverterB1B7. A buyer who needs neither is paying for ratings that don't show up in a blackout.
Plus: 5,017.6 Wh packB7, expandable to 30,105.6 WhB8Ultra X: 12,288 Wh base, expandable to 61.44 kWh on one inverterA2Catalogue cost per watt-hour: lower for the Ultra X than for the Plus
Why it mattersIf you're choosing the Plus for capacity or output, you're choosing the wrong TITAN; if you're choosing it for those two grid-side ratings, be sure you'll use them.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: With the grid down the Plus is a 7,200 W, 5,017.6 Wh battery, and the outage rows show what that means beside the Ultra X's 12,288 Wh.
Read the outage rows as a 7,200 W unit's results, because that's what the Plus is when the grid drops. An 8-hour blackout at 1,645 Wh leaves it at 39% used and the Ultra X at 16%. Both pass that, and both shrug off a CPAP night.
Where the Plus claws something back is between outages, provided you have a 240 V source: its 7,660 W charge pathB15 puts back a 1,645 Wh night in well under half an hour (1,645 ÷ 7,660 ≈ 0.2 h). It still can't stretch one pack across the 4,685 Wh day, falling 420 Wh short where the Ultra X finishes with 5,760 Wh spare.
Runtime: Will It Power Your Gear?
Selected because: The Ultra X's 10,445 Wh usable against the Plus's 4,265 Wh is a gap no outlet rating changes.
continuous output
Every runtime here favors the Ultra X by roughly the battery ratio, 10,445 Wh usable against 4,265 Wh after the flat 15% derate. No outlet rating changes the size of the tank.
Run the Plus's headline circuit through the numbers. A load drawing the full 10,000 W a 41.7 A, 240 V circuit allows would last about an hour on the Ultra X's battery (10,445 ÷ 10,000 ≈ 1.0 h). On the Plus's battery it's more than the 7,200 W discharge rating coversB1, so the question never gets as far as runtime.
Growth Path
Selected because: The Plus grows to 30,105.6 Wh and charges at up to 7,660 W from a 240 V feed; the Ultra X grows to 61.44 kWh on one inverter and takes 10,000 W of solar.
solar input
Both expand, on different scales: the Plus to six packs and 30,105.6 WhB8, the Ultra X to 61.44 kWh on one inverter and 184.32 kWh across threeA2.
The Plus's real growth asset is its charge path rather than its ceiling: up to 7,660 W into the pack through the AC IN/OUT port from a 120/240 V split-phase sourceB15. It's the one rating on this page we can't match on paper for the Ultra X, whose AC charge rate isn't part of this comparison. On solar the order reverses, 8,000 WB4 against 10,000 WA3, and solar is the source still working when the grid is down and the fuel has run out.

Two nights off-grid with essential comfort
Neither unit
Scoring these two at a campsite is a category error: neither travels — the DELTA Pro Ultra X is 298.7 lbs and the TITAN 5000 Plus 121.3 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.

Both survive the night. The DELTA Pro Ultra X finishes at 16% used with 8,800Wh left — 5.3 more nights like it. The TITAN 5000 Plus 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
DELTA Pro Ultra X
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 Pro Ultra X is rated 30dB against the TITAN 5000 Plus'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.

Conclusion
October 4, 2026
Verdict: the DELTA Pro Ultra X, on Power Score margin
Buy the Ultra X if the reason you're looking at the Plus is a big 240 V load that has to keep running when the grid is down. The Plus's 10 kW and 41.7 A figures need solar or grid power flowing in; from its battery alone it delivers 7,200 WB1, which is 30 A at 240 V. The Ultra X delivers 12,000 W from batteryA1, more than the roughly 10,000 W a 41.7 A, 240 V circuit can draw (41.7 × 240), holds about 2.4 times the energy (12,288 ÷ 5,017.6), and is the cheaper battery per watt-hour despite costing $4,300 more. The Plus wins only for the owner who has a 240 V source to feed its 7,660 W charge pathB15 and whose outage loads fit inside 7,200 W.

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 Pro Ultra X rates 4.3/5 (61st percentile of 29 Whole-Home / Off-Grid-class units), and TITAN 5000 Plus rates 4.7/5 (84th percentile of 20 Home Backup-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 Plus (121.3 lbs) is a two-person lift. The DELTA Pro Ultra X (298.7 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 177 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The DELTA Pro Ultra X 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 Plus 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 TITAN 5000 Plus works out at 1.4 years of cover per $1,000 spent against the DELTA Pro Ultra X's 0.6, but that spread is the price gap, not the terms.

Analyst note
The TITAN 5000 Plus 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.

- →The owner with a 240 V source on hand who wants the pack refilled fast between outages: the AC IN/OUT port accepts up to 7,660 W charge-onlyB15, a full refill in well under an hour.
- →The grid-tied household that wants a 41.7 A, 240 V circuit fed through the unit every day, with a 7,200 W battery behind it when the grid dropsB1B2.
- →A time-of-use household that wants the battery to shave peak-rate hours on its own: EcoFlow's X-Fusion 2.0 runs the home on stored energy at peak ratesB25, with OASIS 3.0 as a subscription feature in the EcoFlow appB18.
If neither fits
If your outage loads fit inside 7,200 W and you have no 240 V source to feed a fast charge, skip both: the TITAN 5000 has the same pack, the same box and the same 7,200 W from batteryB1B14, without the grid-side ratings you wouldn't use. And if what you need is power for a trip rather than a house, neither belongs on your list; both are home-backup equipmentA0B11.
The Bottom Line
The Ultra X wins this one because the Plus's most impressive numbers are grid numbers. With the grid down, the Plus is a 7,200 W battery with a 41.7 A outlet it can only fill to 30 A at 240 V, and the Ultra X is the machine that runs that circuit at full size, from a bigger battery that costs less per watt-hour.
Buy the Plus if you own a 240 V source and want its pack back in well under an hour between outages; that's a real advantage, and nothing on this page matches it on paper. Otherwise, if a big 240 V load is why you're here, the Ultra X is the one to buy.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the EcoFlow TITAN 5000 Plus really output 10 kW?
Only with solar or the grid feeding it. EcoFlow's label lists 10 kW max total and 7,200 W for discharge only, so the difference needs solar or grid power flowing in at the same time. On battery alone the Plus delivers 7,200 W, while the DELTA Pro Ultra X delivers 12,000 W.
How fast does the TITAN 5000 Plus recharge?
Fastest from a 120/240 V split-phase feed into its AC IN/OUT port, at up to 7,660 W charge-only, which refills the 5,017.6 Wh pack in well under an hour (5,017.6 ÷ 7,660 ≈ 0.7 h). From solar it takes up to 8,000 W across two inputs, and its 120 V wall inlet is limited to 15 A. EcoFlow's display image shows 8.00 kW in; solar and the 240 V port are both fast paths.
What can the TITAN 5000 Plus's 14-50 outlet run during a power outage?
On battery, whatever fits inside 7,200 W, which works out to 30 A at 240 V (7,200 ÷ 240), not the 41.7 A on the outlet. The 41.7 A rating is reachable with solar or grid power flowing in. For a load that needs the full circuit from battery, the Ultra X's 12,000 W covers it.
Is the DELTA Pro Ultra X better value than the TITAN 5000 Plus?
Per watt-hour of battery, yes: at listed prices the Ultra X costs less for each watt-hour it stores, even though the Plus is $4,300 cheaper overall. It also holds 12,288 Wh to the Plus's 5,017.6 Wh. The Plus is the better buy only if you'll use its 240 V fast-charge path and your loads fit in 7,200 W.
What does the TITAN 5000 Plus add beyond the spec sheet?
EcoFlow sells the TITAN 5000 Plus with a factory pre-wired Smart Home Panel 10 and app control of 10 circuits, and lists it as UL 9540 certified and tested to UL 9540A. For a grid-tied home, EcoFlow says X-Fusion 2.0 lets solar power the home first and the battery cover peak-rate hours. X-Boost 2.0 offers up to 5 kW on each 120 V leg. The OASIS 3.0 scheduling that automates this is a subscription feature in the EcoFlow app.
