Head-to-head test
EcoFlow TITAN 5000 Plus vs Goal Zero Yeti PRO 4000
Against a 120 V-only Yeti, the Plus brings a 41.7 A split-phase outlet and a 240 V charging input that refills its pack in under an hour, and it still costs less, so the only thing left to check is whether your house can use what it's built for.

Spec deltas
The TITAN 5000 Plus is cheaper than the Yeti PRO 4000 by $301, holds 5,017.6Wh to the Yeti's 3,994Wh, and has the one thing the Yeti can't offer at any price: 240 V. EcoFlow's label gives it a 120/240 V split-phase outlet rated 41.7 AA2. The Yeti tops out at 3,600W on 120 V.
The headline figure needs a translation. The Plus is marked 10 kW total, but the battery delivers 7,200W and the rest needs solar or grid power flowing inA1. 240 V at 41.7 A comes to just over 10,000W, which is where that number lives. The bigger outlet is about circuit size and power flowing in, not a stronger battery.
The other half of the Plus is charging. Feed its AC IN/OUT port 240 V and it takes up to 7,660W in charge-only modeA15, enough to fill the pack from empty in under an hour (5,017.6Wh ÷ 7,660W). That speed needs a 240 V source; on the ordinary 120 V, 15 A wall inletA9 it's back to 1,800W at most (120 × 15).
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Against the Yeti, that still leaves the Plus with twice the battery output and a 240 V circuit the Yeti has no way to supply. What the 41.7 A rating adds on top is room for a large 240 V circuit to run on grid power through the Plus day to day, with the battery standing by behind it.
Plus: 10 kW total output, 7,200 W for discharge only; the rest is grid pass-throughA1Split-phase outlet rated 120/240 V, 41.7 AA2, a four-pin 14-50-pattern socketA3Yeti PRO 4000: 3,600 W continuous, 240 V outlets: 0
Why it mattersBuy the Plus to put a big 240 V circuit on your backup system, but size your outage loads to 7,200W, not to the 41.7 A on the socket.
With the grid down, the only 240 V source most homes have is a split-phase generator, and that's where the Plus earns its charging path: run the generator for under an hour, shut it off, and live on quiet battery until the next refill. Fuel and noise both shrink with generator hours. The Yeti's fastest published refill is solar, under two hours from 3,000WB2.
AC IN/OUT port: 120/240 V split-phase input, up to 7,660 W charge-onlyA15Display reads 8.00 kW inA5Wall inlet: 100–120 V, 15 A max, limited to under three hours above 12 AA9
Why it mattersAnyone with a 240 V generator who wants short, infrequent runs get the most from the Plus; without a 240 V source, its headline charging speed never appears.
That's by design. The Plus is meant to feed a panel, where its one big outlet does the work of every circuit behind it. Skip the panel and you're running extension cords from two sockets, which is the one setup where the Yeti's four look better than they should.
Plus outlets: two 120 V 20 A sockets and one 14-50-pattern 41.7 A outletA3Yeti PRO 4000: four AC socketsPlus is sold in bundles with EcoFlow's 240 V Smart Home Panel 10A6
Why it mattersBuyers who won't wire a transfer panel should look at EcoFlow's TITAN 5000 or Classic rather than settle for two sockets on the Plus.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: The Plus's case is how it refills and grows: an 8,000W solar input, a 240 V charging path and a six-pack ceiling.
solar input
The Plus has two fast ways back to full. Solar takes 8,000W across two 40–450 V inputsA4, 5,000W more than the Yeti's 3,000W, and the 240 V AC port takes up to 7,660WA15. Capacity goes to 30,105.6Wh, six packs counting the baseA8, and the charging paths are sized for a bank that big.
The Yeti expands with Goal Zero's batteriesB2, though our ledger states no ceiling. It refills on solar in under two hoursB2, which is quick for its size, but every pack you add still comes out of a 120 V, 3,600W inverter.
Runtime: Will It Power Your Gear?
Selected because: On battery the Plus is a 7,200W machine whatever its outlet says, and runtime shows what that pack actually delivers.
continuous output
Pair the battery with its charger and the Plus has a property the Yeti doesn't. Flat out at 7,200W, its 4,265Wh usable lasts about 0.6 hours (4,265 ÷ 7,200); at 7,660W from a 240 V feed, the 5,017.6Wh pack refills in about 0.65 hours (5,017.6 ÷ 7,660). Empty to full takes about as long as full to empty. The Yeti at its own 3,600W ceiling drains in a little under an hour (3,395 ÷ 3,600) and needs up to two hours of sun to come backB2.
At everyday loads both are comfortable. The 8-hour blackout scenario uses 39% of the Plus and 48% of the Yeti, and a CPAP night takes under a tenth of either. What separates them is everything above 120 V.
Brand Trust
Selected because: A box sited in a utility room for the long haul puts weight on support and service, so both brands' records matter here.
A box sited in a utility roomA11 makes after-sale support part of the price, and neither brand's record is spotless. EcoFlow's support ranges from painless prepaid-label replacements to long waits, and it offers no parts or service once the warranty ends. It also tested subscription paywalls for advanced app features in early 2025 before pausing the plan.
Goal Zero is a Salt Lake City company owned by NRG Energy, and its support, once the justification for its premium, has slipped into long waits and tickets left for weeks through 2025 and 2026. Reviewers still rate the Yeti's app and support teamB1. Call it even on service, and let the 240 V hardware decide.

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 Plus is 121.3 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.

8-Hour Blackout
Keep the essentials running through a night without power
Either unit
Both survive the blackout with similar margin, and both list a UPS mode — compare their stated switchover classes, and remember those are manufacturer ratings, not measurements.

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. The Yeti PRO 4000 lists 100W of USB-C for direct laptop charging; the TITAN 5000 Plus carries no USB-C at all, so a laptop there goes through the inverter and you are carrying its brick.

Neither unit
Scoring these two at a tailgate is a category error: neither travels — the TITAN 5000 Plus is 121.3 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 covers this scenario's 4,685Wh: the TITAN 5000 Plus 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%).

Conclusion
October 4, 2026
Verdict: the TITAN 5000 Plus
Buy the TITAN 5000 Plus over the Yeti PRO 4000. It puts 7,200W from the battery onto a 120/240 V split-phase outlet rated 41.7 AA1A2, against the Yeti's 3,600W at 120 V only; it holds 5,017.6Wh to the Yeti's 3,994Wh; and it costs $3,699 to $4,000. Its catch is the face of the box: two 120 V sockets beside the big outletA3, against the Yeti's four, because it's built to feed a 240 V panel rather than a fan of extension cords. If you won't wire one, the Plus is the wrong TITAN, not the wrong brand.

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 Plus rates 4.7/5 (84th 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 Plus (121.3 lbs) is firmly a two-person lift. It goes where you put it and stays there. That's a 6 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 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.
Yeti PRO 4000: Noise Level Not Disclosed
The TITAN 5000 Plus 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 Plus'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.

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.
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.

Both expand, but the TITAN 5000 Plus's higher solar ceiling (8,000W 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 Plus
Everything on the TITAN side here is EcoFlow's own published ratings, plus our arithmetic. They establish 7,200W from the battery within a 10 kW total that needs solar or grid power flowing inA1, a 41.7 A split-phase outletA2, and a 240 V charging input rated up to 7,660WA15; the 204.8 V pack voltage points to LFP cells by our arithmetic, not by EcoFlow's statementA13. None of it is owner or reviewer experienceA0.
“"Total Output: 10 kW Max (7200W for discharge only)" — the battery delivers 7,200 W, the same as the TITAN 5000; the 10 kW total includes grid pass-through.”
Goal Zero Yeti PRO 4000
The Yeti PRO 4000's field record leans positive. Reviewers single out a durable build, a good app and American-based supportB1, and its 3,000W solar input draws praise for filling it from empty in under two hoursB2. It's well regarded as RV and camping backupB4.
Some owners report 12V errors, including a replacement unit that then stopped charging from solarB3. It's a single thread in our ledger, but it lands on the solar path the Yeti's reputation rests on.
“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.”

“X-Fusion 2.0: solar powers the home first, then charges TITAN for after dark; at peak rates TITAN runs the home on stored energy, and working with the grid through the main panel it can power loads beyond the backed-up circuits.”

Who Should Buy Which
Buy the TITAN 5000 Plus if you…
- →The homeowner with a 240 V split-phase generator who wants to run it for under an hour, refill the pack at up to 7,660WA15, and spend the rest of the outage on quiet battery.
- →The house wiring EcoFlow's 240 V Smart Home Panel 10A6 with a large 240 V circuit it wants on grid pass-through day to day, up to 41.7 AA2.
- →A home that already has rooftop solar and wants to keep it: EcoFlow lists AC coupling with compatible existing solar for the Plus, using the Smart Home Panel 10 and a CT sensorA20.
Buy the Yeti PRO 4000 if you…
- →The camper or RV traveller who wants four plain AC sockets on the box and Goal Zero's Yeti-Ready accessories around it.
- →The buyer charging a stack of laptops and tablets straight from USB-C, where the Yeti's three ports rated up to 100W beat the Plus, which has no USB portsA10.
If neither fits
Anyone without a 240 V feed or a 240 V panel: the Plus's two headline features go unused, and EcoFlow's TITAN 5000 or 120 V-only Classic carries the same 5,017.6Wh packA7 for less.
The Bottom Line
The Plus beats the Yeti on battery, output and price, and adds two things the Yeti can't do at all: put a 41.7 A split-phase circuit on the backup system and refill from 240 V in under an hour. Both need your house to cooperate, with a 240 V panel to feed and a 240 V source to charge from. If yours does, buy the Plus. If it doesn't, the answer is still a TITAN, just a cheaper one.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the EcoFlow TITAN 5000 Plus really output 10kW?
Not from the battery. EcoFlow's label reads 10 kW total with 7,200W for discharge only, so the rest needs solar or grid power flowing in. In an outage, plan on 7,200W, which is still twice the Yeti PRO 4000's 3,600W.
How does the TITAN 5000 Plus charge at 8 kW?
Through its AC IN/OUT port on a 240 V split-phase feed, which takes up to 7,660W in charge-only mode; EcoFlow's display shows 8.00 kW in. At that rate the 5,017.6Wh pack fills from empty in under an hour. The 120 V, 15 A wall inlet is far slower.
What outlets does the TITAN 5000 Plus have?
Two 120 V 20 A sockets and one four-pin 14-50-pattern outlet marked 120V/240V 41.7A. The Yeti PRO 4000 has four AC sockets and no 240 V output in our record, so it has more places for 120 V cords and nothing for a 240 V circuit.
Is the Goal Zero Yeti PRO 4000 cheaper than the TITAN 5000 Plus?
No. The Plus is $3,699 and the Yeti $4,000, so the bigger, 240 V-capable unit is also the cheaper one, by $301. The Yeti's edges are smaller ones: USB ports, which the Plus lacks, and two more plain 120 V sockets on the box.
What does the TITAN 5000 Plus add beyond the spec sheet?
EcoFlow lists X-Fusion 2.0 for the Plus: solar powers the home first, the battery covers peak-rate hours, and working with the grid through the main panel it can power loads beyond the backed-up circuits. AC coupling lets it work with compatible existing rooftop solar, which needs the Smart Home Panel 10 and a CT sensor. It is UL 9540 certified and tested to UL 9540A, and EcoFlow's OASIS 3.0 forecasts solar 3 days ahead and charges off-peak, but the store marks it a subscription feature in the EcoFlow app.
