EcoFlow TITAN 5000 Classic vs Goal Zero Yeti PRO 4000
Neither box puts out 240 V, so this comes down to a straight 120 V count, and the Classic wins it with about a kilowatt-hour more battery, 400W more output and the lower price.

Spec deltas
The TITAN 5000 Classic costs $1,401 less than the Yeti PRO 4000 and carries about a quarter more battery: 5,017.6Wh against 3,994Wh. Most of what follows explains why nothing on the Yeti's side reverses that.
Neither of these speaks 240 V, which is what makes the comparison so clean. EcoFlow's rating label gives the Classic 4,000W at 120 V with no split-phase outputA1, and our record shows no 240 V output on the Yeti either. Neither will reach a well pump or dryer on a 240 V breaker, so this is a like-for-like count of battery, output, solar and price. The Classic wins all four.
The Yeti keeps one honest card: three USB-C ports rated up to 100W, against a single 60W port on the ClassicA8. If your outage plan is mostly laptops charging straight off the box, that's a real convenience. It's also the smallest job either of these will ever do.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
On that level field the Classic leads on every shared line: 1,023.6Wh more battery (5,017.6 minus 3,994), 400W more continuous output, and 200W more solar inputA3, while being the cheaper of the two. There is no trade-off to weigh. The cheaper unit is also the bigger one.
TITAN 5000 Classic: 4,000 W continuous, 120 V only, no 240 V split-phaseA1Yeti PRO 4000: 3,600 W continuous, 240 V outlets: 0Capacity: Classic 5,017.6 Wh, Yeti PRO 4000 3,994 Wh
Why it mattersA household whose backup list is all 120 V circuits can stop considering the Yeti here.
solar input
The bigger pack doesn't cost you anything on the roof. At full rated input both refill from empty in under two hours of strong sun (5,017.6Wh ÷ 3,200W is about an hour and a half; the Yeti's under-two-hours is Goal Zero's own figureB2), and the Classic is holding about a kilowatt-hour more when it's done.
Usable after the flat 15% derate: Classic 4,265 Wh, Yeti PRO 4000 3,395 Wh8-Hour Blackout scenario load: 1,645 WhSolar input: Classic 3,200 WA3; Yeti PRO 4000 3,000 W, empty to full in under 2 hoursB2
Why it mattersIn a multi-day outage with panels, the Classic buys you roughly half an extra blackout per charge without a slower refill.
That splits the jobs cleanly. The Yeti's extra USB-C ports save you a laptop brick or two. The Classic's 30 A port is the one that matters for a whole-home hookup, and EcoFlow sells this unit with its 120 V Smart Home Panel 10A4. One is a desk convenience; the other is how the box reaches the circuits your house actually runs on.
Classic: one USB-C at 60 W and one USB-A at 18 WA8Yeti PRO 4000: three USB-C ports rated up to 100 W and three USB-AClassic: three 120 V 20 A sockets and one 120 V 30 A portA2; Yeti PRO 4000: four AC sockets
Why it mattersOnly a buyer whose backup is mostly laptops and phones should give the Yeti's ports any weight, and even then not the price difference.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: Both stop at 120 V, so runtime on the loads they share is the cleanest test, and 5,017.6Wh against 3,994Wh decides it.
continuous output
Take the flat 15% off both packs and 870Wh separates them: 4,265Wh usable against 3,395Wh. On a 40W CPAP that's nearly 22 hours more (870 ÷ 40).
The 400W of extra continuous output is the smaller win, but it's the margin that keeps a stacked evening load, a microwave plus whatever else is running, from tripping the inverter. Both are 120 V boxes, so the Classic is simply the roomier one on the circuit they share.
Brand Trust
Selected because: The Yeti's case leans on the Goal Zero name, so the brand record has to justify the higher price by itself.
If the Yeti's higher price is buying anything, it's the badge, and the badge has had a rough couple of years. Goal Zero's support, once the reason to pay its prices, has slid into long waits, unanswered emails and tickets that sit for weeks across 2025 and 2026, and its official community forums were shut down. EcoFlow's record is mixed too, from painless prepaid-label replacements to long waits, and it offers no parts or service out of warranty.
Neither record is clean enough to be worth $1,401 on its own. Reviewers do rate the Yeti's build as one of the most durable they've seenB1, and that's the best argument for the Goal Zero name. Toughness pays off in a truck bed. In a utility room, where EcoFlow's label sites the ClassicA9, it's a lot to pay for.
Growth Path
Selected because: Both expand, but only the Classic's ceiling is stated: six packs, 30,105.6Wh.
solar input
The Classic's ceiling is written on its label: 30,105.6Wh, six packs counting the one inside, each extra battery matching the base unit's 5,017.6WhA6. The Yeti expands tooB2, but our ledger states no ceiling for it, so only the Classic gives you a number to plan a growing system against.
One wiring catch before you plan a big array: the Classic's solar input tops out at 250 VA3, so long series strings are off the table and a large roof array goes in parallel instead. It's a detail for whoever does the wiring, not a dealbreaker, and the 3,200W ceiling still edges the Yeti's 3,000W.
Your Life, Your Pick
Selected because: The everyday scenarios show how much of each pack a real load uses, and the Classic finishes each one with more left or less missing.
Most of these rows are a reminder that both units are big. A CPAP night uses 8% of the Classic and 9% of the Yeti; a remote workday, 21% and 27%. At loads like that capacity decides nothing, and you're back to choosing on price, which already points one way.
Van Life Daily is the row that stretches them: a 4,685Wh day that neither covers after the derate. The Classic comes up 420Wh short, about 91% covered; the Yeti is 1,290Wh short at 72%. Either gap closes in well under an hour of strong sun at rated input (420Wh into 3,200W, 1,290Wh into 3,000W), so treat it as a planning note rather than a disqualifier.

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 Classic is 102.5 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.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h

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
Scoring these two at a tailgate is a category error: neither travels — the TITAN 5000 Classic is 102.5 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.

Neither unit
Neither unit covers this scenario's 4,685Wh: the TITAN 5000 Classic 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 Classic
Buy the TITAN 5000 Classic. With both units capped at 120 V, the usual reason to pay more for a station this size, split-phase output, is off the table, and what's left is a count the Classic wins on every line: 5,017.6Wh against 3,994Wh, 4,000W continuous against 3,600WA1, 3,200W of solar against 3,000WA3, and $2,599 against $4,000. The Yeti's clearest published edge is USB-C charging, three ports at up to 100W against one 60W portA8, and nobody backing up a house should pay $1,401 for that.
EcoFlow has not published this price yet. We priced the TITAN 5000 Classic at $2,599 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 Classic rates 3.8/5 (32nd percentile of 20 Home Backup-class units), and Yeti PRO 4000 rates 3.6/5 (16th 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 TITAN 5000 Classic (102.5 lbs) is a two-person lift. The Yeti PRO 4000 (115.7 lbs) is firmly a two-person lift. It goes where you put it and stays there. That's a 13 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 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 TITAN 5000 Classic works out at 1.9 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 Classic publishes its noise level (30dB); 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 Classic's 30dB 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 Classic.

│ 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 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.
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
EcoFlow and Goal Zero are close competitors. Both have established support channels and growing ecosystems. Compare their specific warranty terms and community size for your peace of mind.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow TITAN 5000 Classic
The evidence on the TITAN side is EcoFlow's own published ratings plus our arithmetic on them. The rating label puts the pack at 5,017.6Wh and 204.8 VA5, the output at 4,000W on 120 V onlyA1, and the solar input at 3,200W across 30–250 VA3; the pack voltage works out to 64 LFP cells by our count, not by EcoFlow's statementA11. None of it is owner or reviewer experienceA0.
“4,000 W continuous output at 120 V only — no 240 V split-phase.”
Goal Zero Yeti PRO 4000
Reviewers rate the Yeti PRO 4000's build as one of the most durable they've handled, and credit it with American-based support and a well-liked appB1. Its 3,000W solar input takes it from empty to full in under two hours by Goal Zero's and reviewers' accountsB2, and it's praised as RV and camping backupB4.
The caution comes from owners: some report 12V errors, including one buyer whose first unit went back and whose second threw a 12V error and stopped charging from solarB3. It isn't a broad pattern in our ledger, but it's a fault in exactly the path you'd lean on 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 Classic if you…
- →The homeowner whose backup list is the fridge, the furnace blower, the lights and a sump pump, all on 120 V circuits, who wants the most battery per dollar and plans to wire it through EcoFlow's 120 V Smart Home Panel 10A4.
- →The solar-backed planner who'll add packs over time and wants a stated ceiling to build toward: 30,105.6Wh, six packs in allA6.
- →A buyer in storm country who wants the battery full before the outage: EcoFlow lists Storm Mode, which alerts and charges the battery ahead of severe weatherA17.
Buy the Yeti PRO 4000 if you…
- →The overlander or RV owner already built around Goal Zero's Yeti-Ready coolers and vehicle kits, for whom the Yeti's standing as RV and camping backupB4 is the point.
- →The remote worker who wants several laptops charging straight off the box, through three USB-C ports rated up to 100W, with no inverter in the loop.
If neither fits
Anyone with a well pump, electric dryer or central air on a 240 V breaker: neither box has 240 V output, so that buyer belongs on EcoFlow's split-phase TITAN 5000 or pricing a standby generator. And if the job is a CPAP and a phone overnight, both are oversized several times over; a CPAP night uses under a tenth of either pack.
The Bottom Line
Same 120 V ceiling, different box sizes, and the bigger one costs less. The Classic carries about a kilowatt-hour more battery, gets through roughly half an extra blackout per charge, and still refills inside two hours of strong sun, all for $1,401 less than the Yeti. Unless your whole plan is USB-C laptops, buy the Classic and put the difference toward panels.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the EcoFlow TITAN 5000 Classic run 240V appliances?
No. EcoFlow's rating label lists 4,000W at 120 V only, with no split-phase output. The Yeti PRO 4000 has no 240 V output in our record either, so neither can run a well pump, dryer or range on a 240 V circuit. For that, EcoFlow's split-phase TITAN 5000 is the model to look at.
Is the Goal Zero Yeti PRO 4000 worth more than the TITAN 5000 Classic?
Not on the published numbers. The Classic costs $2,599 against the Yeti's $4,000, carries 5,017.6Wh to the Yeti's 3,994Wh, and puts out 400W more continuously. The Yeti's clearest edge is USB-C: three ports rated up to 100W against one 60W port.
How many blackouts will the TITAN 5000 Classic get through on one charge?
About two and a half of our 8-hour blackout scenario, which draws 1,645Wh. After the flat 15% derate the Classic has 4,265Wh usable, so the arithmetic is 4,265 ÷ 1,645; the Yeti's 3,395Wh usable covers about two. Solar at up to 3,200W refills the Classic in about an hour and a half of strong sun at rated input.
Can you add batteries to the TITAN 5000 Classic?
Yes. It expands to 30,105.6Wh, six packs counting the one inside, using EcoFlow's EF-TT-E5-G1 extra battery. The Yeti PRO 4000 also takes Goal Zero expansion batteries, though our ledger doesn't state its ceiling.
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 and sells it with a factory pre-wired Smart Home Panel 10 that gives app control of 10 circuits. Storm Mode charges the battery before severe weather, and AC coupling lets it work with compatible existing rooftop solar, which needs the Smart Home Panel 10 and a CT sensor. EcoFlow lists no X-Fusion or grid-connection row for the Classic, and its OASIS 3.0 forecasting and off-peak charging is marked a subscription feature in the EcoFlow app.
