EcoFlow TITAN 5000 vs Goal Zero Yeti PRO 4000
The Yeti PRO 4000 has no 240 V output at all, while the TITAN 5000 sends 7,200W of split-phase power through an L14-30, so any house with a well pump or dryer on a 240 V breaker is settled before price comes into it.

Spec deltas
The TITAN 5000 has a 240 V outlet and the Yeti PRO 4000 doesn't, which means one of these can put power on a well pump's circuit in a blackout and the other can't. EcoFlow's label gives the TITAN 7,200W at 120/240 V split-phase, 30 A, through an L14-30 twist-lockA1A2. Our record lists no 240 V output on the Yeti at all.
Look at that twist-lock's own rating: 240 V at 30 A is exactly 7,200W. EcoFlow sized the inverter to the plug, which is what a box built to back up a panel looks like, and it's sold alongside EcoFlow's 240 V Smart Home Panel 10A5. The Yeti tops out at 3,600W on 120 V, half the output and none of the voltage.
And the 240 V machine is the cheaper one, by $801, with about a quarter more battery. The Yeti's best counter is a desk full of USB-C devices, which isn't the problem anyone shopping at this size is trying to solve.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
The loads a house most often can't do without in an outage, a well pump, an electric dryer, a range, central air, sit on two-pole 240 V breakers, and no 120 V box reaches them however big its battery. The TITAN puts 240 V on those circuits through a transfer panel, and EcoFlow sells it with the 240 V Smart Home Panel 10A5. The Yeti can't reach them at all.
TITAN 5000: 7,200 W continuous at 120/240 V split-phase, 30 AA1Outlet: one L14-30 twist-lock marked 120V/240V 30AA2Yeti PRO 4000: 3,600 W continuous, 240 V outlets: 0
Why it mattersIf a well, dryer or air conditioner on a 240 V breaker has to work in an outage, the Yeti is out and this page is decided.
That's the honest catch with a 7,200W inverter on one 5,017.6Wh pack: the 240 V capability is real, but at full tilt a single pack is a sprint. A well pump that runs a few minutes at a time fits it well. A dryer or central air running for hours is a job for extra packs, up to six counting the one insideA7.
Usable after the flat 15% derate: TITAN 5000 4,265 WhTITAN 5000 maximum continuous output: 7,200 WA1Expandable to 30,105.6 Wh, six packs, with the EF-TT-E5-G1 extra batteryA7
Why it mattersBuyers who plan to lean on heavy 240 V loads for hours should budget for extra packs from the start rather than treat the base unit as whole-home coverage.
solar input
So the TITAN takes no longer to fill while banking about a kilowatt-hour more per refill, and its 450 V ceiling lets an installer run long series strings with fewer cable runs. Across a multi-day outage with panels on the roof, that's roughly a kilowatt-hour a day more in the bank, every day the sun shows up.
TITAN 5000 solar: 4,000 W max across 40–450 VA3Yeti PRO 4000 solar: 3,000 W, empty to full in under 2 hoursB2Capacity: TITAN 5000 5,017.6 Wh, Yeti PRO 4000 3,994 Wh
Why it mattersSolar-backed whole-home buyers get more stored energy per sunny day from the TITAN without waiting longer for it.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: Twice the output on a pack about a quarter larger changes how long heavy loads last, and the arithmetic cuts both ways.
continuous output
Twice the output turns into a warning label here. At the Yeti's ceiling of 3,600W its usable 3,395Wh lasts a little under an hour; at the TITAN's 7,200W, the usable 4,265Wh lasts about half an hour (4,265 ÷ 7,200). Bigger inverter, faster drain. Nobody runs either flat out for long, but a 240 V load is exactly the kind that tempts you to.
Turn the load down and the range of this box is striking. On a 40W CPAP the same pack runs about 106.5 hours against the Yeti's 85 (4,265 and 3,395, each divided by 40). Half an hour at full tilt, more than four days at a whisper. Plan the battery around which end of that range your house actually lives at.
Growth Path
Selected because: A 7,200W inverter wants more battery behind it, and the six-pack ceiling and 4,000W solar input are how you give it that.
solar input
A 7,200W inverter on a single pack is a big engine with a modest tank, and EcoFlow's answer is more tank: up to 30,105.6Wh, six identical 5,017.6Wh packs counting the baseA7. The Yeti expands with Goal Zero batteries tooB2, but it's adding fuel to a 3,600W, 120 V engine.
Solar scales with it. The 4,000W input across 40–450 VA3 takes a third more panel wattage than the Yeti's 3,000W, and the high voltage window means fewer, longer strings. If the plan is a big roof array feeding a growing bank, the TITAN is the one built to keep up.
Your Life, Your Pick
Selected because: The everyday rows show how little of either pack ordinary loads use, which is why 240 V, not capacity, settles this pair.
The blackout row is the useful one. An 8-hour outage at 1,645Wh leaves the TITAN with 2,620Wh in reserve and the Yeti with 1,750Wh, so the TITAN finishes the night holding about half another outage the Yeti doesn't have (870 ÷ 1,645).
Van Life Daily asks 4,685Wh and neither covers it after the flat 15% derate: the TITAN is 420Wh short, the Yeti 1,290Wh. On nameplate the TITAN's 5,017.6Wh actually clears that load. Notice what none of these rows test, though: 240 V. That's the axis that decides this pair, and the scenarios can't see it.

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 Yeti PRO 4000 115.7 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.

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 Yeti PRO 4000 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.

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 Yeti PRO 4000 against 60W — which beats the inverter for convenience and wastes less energy.

Neither unit covers this scenario's 4,685Wh: the TITAN 5000 comes up 420Wh short (about 91% covered) (its nameplate 5,018Wh actually clears this — the flat 15% conversion allowance is what tips it under), the Yeti PRO 4000 1,290Wh (72%). 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
Buy the TITAN 5000. It delivers 7,200W at 120/240 V split-phaseA1, twice the Yeti's 3,600W, and the Yeti has no 240 V outlet to answer with. It also carries 5,017.6Wh against 3,994Wh, takes 4,000W of solar against 3,000WA3, and costs $3,199 to the Yeti's $4,000. The Yeti's real advantages sit at the small end, three USB-C ports at up to 100W against one 60W portA9, and they won't move anyone shopping at this size.
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.
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 Yeti PRO 4000 rates 3.6/5 (16th 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 Yeti PRO 4000 (115.7 lbs) is a two-person lift. The TITAN 5000 (119 lbs) is firmly a two-person lift. It goes where you put it and stays there. That's a 3 lb difference.
UPS Switchover: ≤15ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The Yeti PRO 4000 is rated ≤15ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. 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.
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 works out at 1.6 years of cover per $1,000 spent against the Yeti PRO 4000's 1.3, but that spread is the price gap, not the terms.
Yeti PRO 4000: Noise Level Not Disclosed
The TITAN 5000 publishes its noise level (39dB); the Yeti PRO 4000 doesn't publish one. That isn't evidence the Yeti PRO 4000 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 Yeti PRO 4000 before deciding.
Full record above — the Test Desk pick is the TITAN 5000.

│ 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.
Goal Zero
Ecosystem
Focused — a compact current line (6th-gen Yeti and Yeti Pro series), the previous-gen X series now out of stock across every model on Goal Zero's own store (checked 2026-09-13: 200X, 500X, 1000X, 1500X, 3000X, 6000X, some listed only as open-box), so buying one new means finding retailer stock, Sherpa power banks for the under-100Wh tier, plus Alta coolers, Nomad/Ranger solar panels, and vehicle integration kits
Support
US-based company (Salt Lake City, owned by NRG Energy). Historically considered premium support, but 2025-2026 reports describe long wait times, unresponsive email communication, and tickets going unaddressed for weeks. The "premium support justifies premium pricing" argument is weakening.
Community
Small but loyal — strong following in overlanding and preparedness communities. Official community forums were recently shuttered, frustrating long-time users.
App experience
Rated 4.4/5 iOS (~1,200 ratings) but recent reviews skew negative — recurring connectivity issues, crashes, and stability problems.
Unique strength
Pioneer of the portable power market — strongest brand heritage. US-based company with ruggedized, weather-resistant designs (IP ratings vary by model). Integrated "Yeti-Ready" ecosystem with coolers, lights, and vehicle kits.
Worth knowing
Typically the priciest brand per watt-hour — though individual pairings vary, and on some pages the Yeti is the cheaper energy. Support quality has declined from its "premium" standard. Perceived as competitively stagnant vs. faster-innovating Chinese competitors. Reliability reports on newer models are concerning.
Analyst note
This is where EcoFlow's breadth stops being a slogan: it makes the 240 V home panel this unit is sold with, so the whole backup chain comes from one company and one support line. Goal Zero's ecosystem points the other way, toward coolers, lights and vehicle kits, which suits a rig better than a breaker box.

Analyst note
Both expand, but the TITAN 5000's higher solar ceiling (4,000W vs 3,000W) 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 on the TITAN side is EcoFlow's own published ratings, with our arithmetic on top. The label establishes 7,200W at 120/240 V split-phase, 30 AA1, an L14-30 outlet beside three 120 V 20 A socketsA2, 4,000W of solar across 40–450 VA3, and a second AC port that passes up to 7,200W through in bypass modeA14. None of this is owner or reviewer experienceA0.
“7,200 W continuous output with 120/240 V split-phase at 30 A.”
Goal Zero Yeti PRO 4000
Goal Zero and reviewers agree on the solar: 3,000W in, empty to full in under two hours, with idle efficiency that drew praiseB2. Reviewers also call the build one of the most durable they've seen and credit the American support teamB1, and the unit has a following as RV and camping backupB4.
Against that sits a reliability thread from owners: some report 12V errors, one of them on a replacement unit that then wouldn't take solarB3. It's a minority entry in our ledger, but worth reading before you count on the Yeti through a long outage.
“Weighs about 115.7 lbs — a two-person unit to move — with one of the most durable builds reviewers have seen, backed by American-based support and a great app.”

Who Should Buy Which
Buy the TITAN 5000 if you…
- →The rural homeowner on a well whose pump sits on a 240 V breaker and has to keep running when the grid doesn't; the TITAN's L14-30A2 reaches that circuit and the Yeti has nothing that does.
- →The household wiring a 240 V transfer panel now, using EcoFlow's 240 V Smart Home Panel 10A5, with a roof array ready to feed a 4,000W solar inputA3.
- →A home that already has rooftop solar and a 240 V panel to feed: EcoFlow says the TITAN 5000 AC-couples to compatible existing solar through the Smart Home Panel 10 and a CT sensorA19.
Buy the Yeti PRO 4000 if you…
- →The RV or overland traveller whose rig runs entirely on 120 V and already carries Goal Zero's Yeti-Ready coolers and vehicle kits.
- →The buyer who'd rather have three USB-C ports rated up to 100W on the box than an inverter brick for every laptop.
If neither fits
Anyone whose loads are all 120 V: the TITAN 5000's split-phase is wasted on you, and EcoFlow's 120 V-only TITAN 5000 Classic puts the same 5,017.6Wh packA6 in a cheaper box. And anyone hoping to run central air all day from one battery should price a standby generator, or plan on several extra packs.
The Bottom Line
One of these has a 240 V outlet sized exactly to its 7,200W inverter, and the other has no 240 V at all. That settles it for anyone with a well pump or dryer on a two-pole breaker, and the TITAN is also the bigger battery and the cheaper box, by $801. Buy the TITAN 5000, and if you plan to lean on that 240 V for hours, buy a second pack with it.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the Goal Zero Yeti PRO 4000 run a 240V well pump?
No. Our record lists no 240 V output on the Yeti PRO 4000; it delivers 3,600W at 120 V. The TITAN 5000 has a 120/240 V split-phase L14-30 outlet rated 30 A, so it can supply a 240 V circuit the Yeti can't reach.
What 240V outlet does the EcoFlow TITAN 5000 have?
One L14-30 twist-lock marked 120V/240V 30A, beside three 120 V 20 A NEMA 5-20R sockets. 240 V at 30 A works out to 7,200W, which is exactly the TITAN's rated continuous output.
How long does the TITAN 5000 last at full power?
About half an hour. After the flat 15% derate the pack holds 4,265Wh usable, and 4,265 ÷ 7,200 is roughly 0.6 hours. At light loads it's another story: a 40W CPAP would run for more than four days. Extra packs take it to 30,105.6Wh.
How fast does the TITAN 5000 recharge from solar?
In about an hour and a quarter of strong sun from empty at its full 4,000W input (5,017.6Wh ÷ 4,000W). The Yeti PRO 4000's 3,000W input fills its smaller pack in under two hours, so the two take similar time while the TITAN stores about a kilowatt-hour more.
What does the TITAN 5000 add beyond the spec sheet?
The TITAN 5000 is UL 9540 certified and tested to UL 9540A, and EcoFlow sells it with a pre-wired Smart Home Panel 10 with app control of 10 circuits. EcoFlow says it couples to compatible existing rooftop solar through that panel and a CT sensor, and its Storm Mode charges the battery before severe weather. OASIS 3.0 scheduling is marked a subscription feature in the EcoFlow app.
