Head-to-head test
BLUETTI AC240P vs Goal Zero Yeti 1500 (6th Gen)
At the same checkout price, the BLUETTI AC240P is the bigger battery (1,843Wh to 1,505Wh), the stronger inverter, and the faster solar refill; the Yeti 1500 (6th Gen)'s one real answer is weighing 19 pounds less, so buy on how often you actually lift it.

Spec deltas
The BLUETTI AC240P costs $38 less than the Goal Zero Yeti 1500 (6th Gen), $1,462 against $1,500, and hands you 338Wh more battery, 1,843Wh to 1,505Wh. That's the whole tension in one line: the pricier unit is also the smaller one.
Spec for spec, the BLUETTI is the more capable box. It runs 2,400W continuous to the Yeti's 2,000W, pulls 1,200W of solar to the Yeti's 900W, carries a 6-year warranty against 5, and can bolt on expansion batteries when the Yeti is sealed at 1,505Wh for life. It's also rated IP65, proven in a six-hour rainstorm and on a saltwater-sprayed sailboatA2, where the Yeti's aluminum shell is splash-resistant IPX4.
The Yeti pushes back in exactly one place, and it's a real one. It weighs 52.75 lbs against the BLUETTI's 72, 19 pounds you feel every time the unit leaves the floor. Everything else here is a footnote to that single tradeoff: a lighter, US-built box you pay more for and get less of, against a heavier one that out-specs it for less money.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Add the AC240P's 1,200W solar input against the Yeti's 900W and its 6-year warranty against 5, and the pattern is total. The Yeti isn't the budget pick that trades power for a lower price; it's the pricier unit that trades away power.
The BLUETTI AC240P is $1,462; the Yeti 1500 (6th Gen) is $1,500The AC240P holds 1,843Wh and runs 2,400W continuous; the Yeti holds 1,505Wh and runs 2,000W
Why it mattersCross-shop these as same-price rivals and the AC240P is the default; the Yeti needs a specific reason, and there's only one, to overcome it.
cost / lifetime kWh
Since the two are a wash on lifetime economics, weight is the tiebreaker the Yeti actually wins. For a unit that lives on a shelf and backs up the house, the 19 pounds never comes up; for one that rides in and out of a truck bed or up basement stairs every week, it's the only spec that touches your hands.
The Yeti 1500 weighs 52.75 lbs; the AC240P weighs 72 lbsLifetime cost is nearly identical: $0.23 per kWh for the BLUETTI, $0.25 for the Yeti
Why it mattersFrequent solo carriers should genuinely look at the Yeti; anyone who sets it down and leaves it is paying more for a lightness they'll never use.
rated cycles
At daily cycling that's 9.6 years for the BLUETTI against 11 for the Yeti, both far past their 6- and 5-year warranties. The Yeti's cycle-count lead is real on the sheet and invisible in a garage; neither battery dies of cycles before it dies of age.
The Yeti is rated for 4,000 cycles; the AC240P for 3,500The AC240P's larger 1,843Wh tank moves more energy per cycle, 6,451 total lifetime kWh against the Yeti's 6,021
Why it mattersDon't pay the Yeti's premium on the strength of its 4,000-cycle rating: it's not the longer-lived buy in kWh terms, and both outlast the warranty many times over.
The Yeti still kept a modem and router alive through a winter storm in testingB5, so 25ms backs up a home office fine. But for a desktop without its own battery, or a jobsite in the rain, the AC240P's faster, better-sealed answer is the safer one, and it's the cheaper unit here, not the dearer.
The AC240P is rated IP65 and switches to battery in 15ms; the Yeti is IPX4 and switches in 25msIP65 is dust-tight and low-pressure water-jet resistant; IPX4 is splash resistance only
Why it mattersOutdoor, jobsite, and sensitive-electronics buyers lean AC240P; pure indoor backup can treat the UPS gap as a non-issue.
The specific dimensions that decide these two units — everything else is a tie.
Portability & Form Factor
Selected because: Weight is the only axis the Yeti wins and the single reason to pick it; the 19 lb gap deserves top billing.
weight
This is the section the Yeti wins, and it wins it cleanly. At 52.75 lbs it's 19 pounds lighter than the 72-lb AC240P, the line between hauling the unit alone and wanting a second set of hands. Reviewers landed on 'luggable, not carryable' for the YetiB8, which puts the heavier BLUETTI firmly in plan-your-lift territory.
Weigh that against what the weight buys. The BLUETTI's extra pounds are partly its bigger 1,843Wh battery and partly its IP65-sealed, rugged build, mass with a purpose rather than padding. If the unit mostly stays put, none of it costs you anything. If you're the one lifting it in and out of a vehicle several times a month, the Yeti's lighter aluminum body is worth real money to your back, and it's the honest reason to pass on the cheaper, more capable BLUETTI.
Lifetime Value
Selected because: Lifetime cost is nearly tied ($0.23 vs $0.25); state it honestly so it isn't oversold as a BLUETTI blowout.
cost / lifetime kWh
The two units cost almost the same to own over their lives, and that's the honest headline: $0.23 per kWh for the BLUETTI against $0.25 for the Yeti. The BLUETTI's lower price and bigger tank push one way; the Yeti's higher 4,000-cycle rating pushes back, and they nearly cancel. This is not the lifetime-cost blowout some BLUETTI-versus-premium matchups turn into.
Where the BLUETTI does pull clear is total energy and warranty coverage. Its larger capacity and 3,500 cycles add up to 6,451 lifetime kWh against the Yeti's 6,021, some 430 kWh more over the life of the unit, and its 6-year warranty spreads the purchase across more covered time, $244 per warranty year against $300. Close on cents per kWh, a step ahead on everything the cents don't capture.
Growth Path
Selected because: AC240P expandable vs Yeti sealed at 1,505Wh, a real structural difference for buyers who may grow.
solar input
The AC240P can grow; the Yeti can't. BLUETTI's unit takes expansion batteries that push it past its 1,843Wh base toward partial-home-backup territory, while the Yeti 1500 (6th Gen) is sealed at 1,505Wh: the size it is on the shelf is the size it is for life. For a buyer whose needs are stable, that's a non-issue. For one who suspects next year brings a bigger fridge, a well pump, or a longer outage, it's a door left open on one unit and welded shut on the other.
One caveat in the Yeti's favor: buying expandable and never expanding is just carrying a base unit with a port you never use. But the AC240P is already the cheaper, larger, longer-warrantied box before expansion enters the picture, so here the growth path is a free option on top of a unit that was ahead anyway, not a premium you pay for maybe-someday.
What the Specs Don't Tell You
Selected because: UPS speed (15 vs 25ms), disclosed vs undisclosed noise, shared 3,600W surge: the concrete spec-true differentiators.
rated cycles
Three concrete differences sit outside the capacity headline. The BLUETTI switches to battery in 15ms, inside the sub-20ms window that makes a true standby UPS; the Yeti's 25ms is a hair slower, in basic-standby range, fine for a router, a gamble for a bare desktop mid-save. Both units share an identical 3,600W surge ceiling, so they start the same motors; the BLUETTI just sustains more afterward, 2,400W continuous to the Yeti's 2,000W.
The noise line is the telling one. BLUETTI publishes 45dB under load, audible but a number you can plan a room around. Goal Zero publishes no noise figure at all for the Yeti, and reviewers confirm its fans do come up near full outputB1; the quietest spec on the Yeti's sheet is the one it declines to print. A disclosed 45dB beats an undisclosed unknown every time you're deciding where in the room the thing goes.
Brand Trust
Selected because: Cross-brand: BLUETTI value plus inconsistent support vs Goal Zero US heritage plus declining support and a few reliability reports.
Cross-brand, this is BLUETTI's value engine against Goal Zero's heritage. BLUETTI builds the widest lineup in the category and the best capacity-per-dollar in it, and the AC240P is a clean example: more Wh, more output, more warranty, less money. The catch is support, the most inconsistent in the space, email-based with timezone lag, smooth for some buyers and a weeks-long runaround for others, and buying direct tends to go better than through a third party.
Goal Zero is the US-based pioneer, Salt Lake City built, with a rugged reputation the aluminum Yeti earnsB6. But its old 'premium support justifies premium price' bargain is fraying: 2025-2026 reports describe long waits and unanswered tickets, and a couple of REI buyers hit outright charging failures and firmware-triggered connectivity problems on this new SKUB10B11, against an otherwise positive professional-review consensus. Neither brand has a clean support edge right now, which leaves the hardware and the price to decide it, and both favor the BLUETTI.

Two nights off-grid with essential comfort
Neither unit
Neither unit covers this scenario's 2,100Wh: the AC240P comes up 533Wh short (about 75% covered), the Yeti 1500 (6th Gen) 821Wh (61%). Either gets you most of the way, so this is a scenario you plan around rather than one you should rule them out for.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
Neither unit quite covers a full 8-hour whole-home-style blackout load. The BLUETTI gets closest, landing just over its own usable ceiling, while the Yeti falls further short. Treat both as strong partial-outage or single-room backups rather than whole-house boxes; for a true 8-hour whole-home cushion, size up.

SCN-03 · 8 hours · needs 320Wh
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 1500 (6th Gen) 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
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
AC240P
This is the one everyday scenario that separates them, and the BLUETTI takes it. A full laptop-monitor-router workday leaves it more headroom, well under two-thirds of its capacity, than the Yeti, which handles the same day with less room to spare. Both finish it; the BLUETTI just finishes it easier.
Battery budget usedlower = more headroom

SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Either unit
Both handle game day easily. Since capacity isn't the deciding factor, weight is: at 52.8 lbs the Yeti 1500 (6th Gen) is the one you'll be glad you brought. Fan noise under load is worth a listen too — it's audible in the lulls between songs.

Conclusion
July 18, 2026
Verdict: the AC240P
Buy the BLUETTI AC240P unless you're carrying it often and alone. For $38 less than the Yeti 1500 (6th Gen) you get 338Wh more capacity, 400W more continuous output, 300W more solar input, a year more warranty, and a battery you can actually expand later, none of which the Yeti answers. The two are nearly tied on the number that usually settles these, lifetime cost per kWh ($0.23 against $0.25), because the Yeti's higher 4,000-cycle rating offsets its smaller tank. So this isn't a longevity blowout; it's a same-money, more-machine call. The Yeti earns its keep on exactly one axis the spec sheet can't oversell: at 52.75 lbs it's 19 pounds lighter than the 72-lb BLUETTI, the difference between a one-person carry and a two-hands, bent-knees lift. Move it in and out of a truck weekly and that matters more than any single spec; leave it parked and it never shows up.

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, AC240P rates 4.1/5 (48th percentile of 24 Everyday-class units), and Yeti 1500 (6th Gen) rates 3.4/5 (4th percentile of 24 Everyday-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.
The AC240P's One Real Cost: 72 Pounds
This is the honest catch on our pick. At 72 lbs the AC240P is a two-hands, bent-knees lift you plan around, not one you do casually on stairs, 19 pounds more than the Yeti. Most of that mass is a bigger battery and a rugged, sealed shell, so it's weight with a purpose, but your back doesn't care about the reason. If you move the unit often and alone, this is the one line on the page that favors the Yeti.
AC240P: 45dB Under Load
45dB is about as loud as a running refrigerator. The Yeti 1500 (6th Gen) publishes no figure to compare it against, which cuts both ways. For most people, fan noise around 45dB and up is where sleep starts to suffer.
Yeti 1500 (6th Gen): Fixed Capacity
The Yeti 1500 (6th Gen) is sealed at 1,505Wh — fine if that covers you, but it's the ceiling. By contrast the AC240P can add expansion batteries, so if your needs grow past 1,505Wh it has somewhere to go the Yeti 1500 (6th Gen) doesn't — though at this size expansion buys longer runtimes on the same loads, not a home-backup system.
Surge Power: Same Ceiling, Different Ratio
Both units surge to the same 3,600W. The Yeti 1500 (6th Gen) shows a higher surge-to-continuous ratio (1.8× vs 1.5×) only because its continuous rating is lower — the ratio is the same ceiling divided by a smaller number, not extra starting ability. On what either can actually start, they are identical; the difference is what they can hold afterwards.
Warranty Comparison
The AC240P is covered for 6 years against the Yeti 1500 (6th Gen)'s 5 years. An underrated factor if you're keeping this unit for years.
One Published Number Beats None
BLUETTI prints 45dB under load for the AC240P, audible, but a figure you can plan a room around. Goal Zero publishes no noise number for the Yeti at all. A disclosed weakness you can design around is worth more than an undisclosed unknown you meet only after the fans spin up.
Full record above — the Test Desk pick is the AC240P.

Analyst note
Both units have similar long-term ownership costs ($0.23/kWh vs $0.25/kWh). The price difference is what you see on the sticker — neither is a hidden bargain or rip-off. One caution on the lifespan row: the Yeti 1500 (6th Gen) takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the AC240P still delivers more over its shorter horizon (6,451 vs 6,021 kWh). Years measure wear, not usefulness.
Brand trust
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.
Support
The most inconsistent support in the space. Heavily email-based with China timezone delays. Some users get smooth, efficient service; others report weeks of troubleshooting runarounds, being offered discounts on new units instead of repairs, and confusing third-party purchase claim processes. Buying direct from Bluetti's website tends to produce better support outcomes.
Community
Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.
App experience
Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.
Unique strength
Among the best capacity-to-price ratios available — several Elite and Apex units are the lowest $/Wh in the catalog. Widest product diversity including industry-firsts like sodium-ion cold-weather units and dual solar+alternator vehicle hubs. Full LFP standardization across the lineup, though rated cycle life spans 2,500 (EB3A) to 6,000 (Elite units) — check the specific model. Dual-voltage (120V/240V) in flagships.
Worth knowing
Customer support inconsistency is the #1 risk factor. Older/discontinued units may become unrepairable — no spare parts policy for some models. Some reports of erratic communication from support agents.
Goal Zero
Ecosystem
Focused — a compact current line (6th-gen Yeti and Yeti Pro series), the previous-gen X series still widely sold, 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
Goal Zero positions itself as a premium brand with stronger support infrastructure, while BLUETTI competes on value. The question is whether the Goal Zero ecosystem and support premium is worth it for your use case.
Growth path
AC240P
EXPANDABLESupports BLUETTI expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 1,843Wh.
Accepts up to 1,200W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
Expansion batteries are BLUETTI-specific. You're investing in the BLUETTI ecosystem.
Yeti 1500 (6th Gen)
FIXED CAPACITYFixed at 1,505Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 900W of solar. Suitable for a 1-2 panel setup.
Generous port selection supports complex multi-device setups.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
The Yeti 1500 (6th Gen) is sealed at 1,505Wh, which is fine if that covers you. The AC240P starts at 1,843Wh and can grow beyond it with BLUETTI expansion batteries — though at this size expansion means longer runtimes on the same loads, not a path to home backup. More hours, not more house.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
BLUETTI AC240P
Field reports on the AC240P center on its rugged, weatherproof build. One reviewer left it out in a six-hour rainstorm and found water beading off with the interior bone dry, and ran it through constant saltwater spray on a sailboat with no moisture intrusion after a wipe-downA2. The one caveat is that the IP65 rating only holds with every port cover closed: plug a cable in and run it in the rain and you've broken the sealA1.
Beyond weatherproofing, the AC240P reads as the premium, higher-capacity end of BLUETTI's rugged line, LFP chemistry, a fast wall charge that reaches most of full quickly, and headroom to expand into a large multi-kWh bank laterA4. The 1,843Wh version is the bigger-tank option in the family, wearing the high-visibility orange IP65 shell for buyers who want the extra capacity and don't mind being seen with itA3.
“IP65 water- and dust-resistant, but the protection applies only when all port covers are closed; using it with cables plugged in compromises the rating, and it shouldn't be used in the rain that way.”

Goal Zero Yeti 1500 (6th Gen)
The Yeti 1500 (6th Gen) is new enough, it launched around early 2026, that long-term ownership data is still thin, so the field signal leans on hands-on reviews and a small early buyer sample. What's there is mostly positive: a full wall charge in just over an hour, a CPAP run overnight that still left well over half the battery by morning, and a clean handoff that kept a modem and router alive through a winter stormB2B4B5. The aluminum enclosure drew praise for a tool-like, premium feel that shrugged off rocky roads and speed bumpsB6.
The knocks are real but fewer. Reviewers note the fans become audible pushing near the 2,000W limitB1, the solar recharge runs slower than Goal Zero's claim once clouds and angles are honestB3, and the proprietary 6mm ports don't play with older Yeti Tank batteriesB9. The one that would give me pause: a couple of early REI buyers reported the unit refusing all charging inputs outright, plus firmware-update connectivity trouble, paired with slow supportB10B11. A minority signal on a new SKU, but the kind worth watching before the warranty is your only recourse.
“When pushing the inverter near its 2,000W limit, the internal cooling fans become audible — not loud, but noticeable in a quiet room.”

Who Should Buy Which
Buy the AC240P if you…
- →Anyone cross-shopping these at the same price who wants the most battery, output, and solar for the money: the AC240P beats the Yeti on all three and costs $38 less.
- →Buyers who might grow into more capacity later: the AC240P expands past its 1,843Wh base; the Yeti is sealed at 1,505Wh for good.
- →Outdoor, jobsite, and wet-weather users who need the IP65 seal and the 15ms standby-UPS handoff for sensitive gear.
Buy the Yeti 1500 (6th Gen) if you…
- →People who lift and carry the unit often and alone: 52.75 lbs against 72 is 19 pounds your back notices every trip.
- →Buyers who want a US-built, aluminum-bodied unit and value its 4,000-cycle rating and 140W USB-C charging over raw capacity.
- →Existing Goal Zero owners with Yeti-Ready coolers, lights, or vehicle kits already in the ecosystem.
If neither fits
Anyone sizing for an actual weekend camp, a full 8-hour whole-home blackout, or daily van-life draw should look a class up: both fall short of all three, the Yeti needing up to 366% of its capacity and the BLUETTI up to 299% of its own. Loads like that want a 2,000Wh-plus unit with real expansion, not either of these asked to punch well above 1,843Wh.
The Bottom Line
Buy the AC240P. At $38 less than the Yeti 1500 (6th Gen) it's the bigger battery, the stronger inverter, the faster solar refill, and the only one of the two you can expand, and it's a near-tie on the lifetime cost per kWh that usually settles these, so none of that extra capability costs you anything long-term.
The Yeti has exactly one answer, and it's a good one for the right person: 19 pounds less to lift, in a US-built aluminum body. If you carry the thing often and alone, that's worth paying more to get less. If you don't, the cheaper, more capable BLUETTI is the easy call.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the BLUETTI AC240P better than the Goal Zero Yeti 1500 (6th Gen)?
For most buyers, yes, and it costs $38 less. The AC240P gives you 338Wh more capacity, 400W more continuous output, 300W more solar input, an extra year of warranty, and room to expand, while the two are nearly tied on lifetime cost per kWh. The Yeti's one clear win is weight: at 52.75 lbs it's 19 pounds lighter than the 72-lb BLUETTI, which matters if you carry it often.
Which is lighter, the AC240P or the Yeti 1500?
The Yeti, by 19 pounds, 52.75 lbs against the AC240P's 72. That's the difference between a one-person carry and a two-hands, bent-knees lift, so if the unit rides in and out of a vehicle regularly, the Yeti is the easier one to live with. If it mostly stays put, the weight gap rarely comes up.
Can the BLUETTI AC240P expand when the Yeti 1500 can't?
Correct. The AC240P accepts BLUETTI expansion batteries to grow past its 1,843Wh base, while the Yeti 1500 (6th Gen) is sealed at 1,505Wh with no expansion path. If you might need more capacity down the road, that's a real point for the BLUETTI; if your needs are fixed, it doesn't matter.
Is the new Yeti 1500 (6th Gen) reliable?
Professional reviews of this 2026 LiFePO4 model are mostly positive on charging speed, CPAP endurance, and UPS backup. But it's a new SKU with thin long-term data, and a few early REI buyers reported total charging failures and firmware-related connectivity issues alongside slow support. That's a minority signal against a positive review consensus, worth watching rather than panicking over.
Do the AC240P and Yeti 1500 work as a home backup or UPS?
Both do, with an edge to the BLUETTI. The AC240P switches to battery in 15ms, inside the sub-20ms window for a true standby UPS, while the Yeti's 25ms is basic-standby, still enough to keep a router or modem alive through an outage as one winter-storm test showed. For a bare desktop with no battery of its own, the faster BLUETTI handoff is the safer pick.
