Spec deltas
The AC70 costs $359 and the Yeti 700 costs $700, and the cheaper one is also the bigger, stronger, faster-charging box. 768Wh against 677Wh. A 1,000W inverter against 600W. 500W of solar input against 200W. BLUETTI wins the specs that cost money to win, and it wins them at 47 cents a watt-hour to Goal Zero's $1.03.
Goal Zero's counterarguments are narrow and real. The Yeti 700 is rated for 4,000 charge cycles to the AC70's 3,000, it weighs 19.3 lb against 22.5, and its case carries an IPX4 rating and handles temperature extremesB2. If your version of this purchase involves walking somewhere with it, those 3.2 pounds are the one thing on this page that $341 cannot buy back.
Most of what buyers expect to separate these two doesn't. Both carry five-year warranties, both push 100W over USB-C, and both hand off to battery in 20ms when the grid drops. That last one is a genuine dead heat, which takes the UPS question off the table entirely. What's left is whether three pounds is worth more to you than every other number here.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
solar input
When neither box can carry the trip on a single charge, capacity stops being the deciding spec and refill speed becomes it. The AC70 tops up over lunch and goes back to work. The Yeti spends most of an afternoon climbing back to less than the AC70 started with, and on a cloudy day that is the difference between topping up and falling behind.
AC70: 768Wh capacity, 500W maximum solar inputYeti 700: 677Wh capacity, 200W maximum solar inputWeekend Camping needs 2,100Wh — 322% of the AC70's usable capacity and 365% of the Yeti's, so neither finishes on one charge
Why it mattersIf a solar panel is part of your plan, compare charge windows rather than watt-hours; this gap decides your second day out, not your first.
rated cycles
The longevity advantage is real and it expires before you can spend it. Both units run decades past their five-year warranty on weekend duty, so a cell rated to last 38 years instead of 28 is not selling you more use. It is selling you a bigger number on a spec sheet you will have replaced long before either battery is tired.
Yeti 700: 4,000 cycles, 2,708 kWh of total lifetime energy, $700AC70: 3,000 cycles, 2,304 kWh of total lifetime energy, $359Both carry a five-year warranty; on weekend use the cycle ratings work out to 38.5 years for the Yeti and 28.8 for the AC70
Why it mattersIf cycle count is why you were leaning Goal Zero, it is the wrong reason — neither of these dies of old age in a weekend-use household.
A near-miss is only a problem once, provided you can fix it. Bolt an expansion battery onto the AC70 and the tailgate stops being a coin flip and the workday stops being a stretch. The Yeti's answer to "I needed slightly more" is to buy a second Yeti, which is the most expensive way to add 677Wh anywhere in this comparison.
Tailgate Party needs 670Wh: 103% of the AC70's usable capacity, 116% of the Yeti'sRemote Workday needs 910Wh: 139% of the AC70's usable capacity, 158% of the Yeti'sThe AC70 accepts BLUETTI expansion batteries; the Yeti 700 is sealed at 677Wh
Why it mattersIf your real load list lands anywhere near these numbers, buy the expandable one, because near-misses do not stay near.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: $359 against $700, and the cheaper unit is also the cheaper energy over the life of the cells, even though the Yeti is rated for a third more cycles.
cost / lifetime kWh
Goal Zero's cycle rating is the strongest card in its hand and it still loses the money argument. Across the full life of the cells the Yeti moves 2,708 kWh to the AC70's 2,304, roughly 400 kWh more energy, and it charges $341 for the privilege. That works out to 26 cents a lifetime kilowatt-hour against 16.
Here is the version that is easier to feel. Both units carry the same five-year warranty. One costs $72 a year to own across that term and the other costs $140. The extra money is not buying you more coverage, more capacity or more output. It is buying you the same warranty at nearly twice the price.
Runtime: Will It Power Your Gear?
Selected because: The AC70 holds 768Wh to the Yeti's 677Wh and runs 1,000W continuous to its 600W, so it is both the longer-lasting and the stronger of the two.
continuous output
The only load on this page either unit actually finishes is the CPAP night, and both walk it. A 320Wh night is around half of what each can usefully deliver, so you wake with reserve either way. Everything else on the list runs them flat. Once that is true, the interesting number stops being how much either one holds. It is what you do at 40%, and only one of these two has a fast answer.
Worth saying before the spec table talks you into it: the AC70's 1,000W inverter is not the reason to buy the AC70. The Yeti's 600W clears the peak draw of every scenario modeled here, so nothing on the list refuses to start on it. The extra output is headroom for the appliance you buy next year without reading the label, not capability you will miss on a normal Saturday.
Portability & Form Factor
Selected because: The Yeti 700's one clear win, and the only one money cannot undo: 19.3 lb against 22.5 lb.
weight
Three pounds is the Yeti 700's entire physical case, and it is a real three pounds. 19.3 lb against 22.5 lb is the line between grabbing something one-handed and committing to it with both, and reviewers read the unit exactly that way — light and simple, built for quick trips rather than heavy workB3. It also carries an IPX4 rating and tolerates temperature extremesB2, which is more than the AC70's sheet claims.
Then price the pounds. Those 3.2 lb cost $341, and on the way out they cost you 91Wh of capacity, 400W of continuous output and 300W of solar input. If you are walking a trail with this thing on your back, that might still be your trade to make. If it rides in a trunk and gets carried twenty feet to a picnic table, you have paid a premium to lift less, once a weekend.
Growth Path
Selected because: The AC70 takes BLUETTI expansion batteries; the Yeti 700 is sealed at what you buy.
solar input
677Wh is not merely what the Yeti holds. It is what the Yeti will always hold. That is a defensible choice on a unit built to be light and simpleB3, and it becomes a real constraint sitting next to a rival that starts higher and keeps going.
The price per watt-hour makes the ceiling sting more. The AC70 stores energy at 47 cents a watt-hour and the Yeti at $1.03, so every watt-hour you eventually add to the Yeti arrives at the worse rate, inside a whole second purchase. Expansion is not a feature you use on day one. It is the reason day four hundred does not cost you full price all over again.
What the Specs Don't Tell You
Selected because: The AC70 doubles to a 2,000W surge where the Yeti reaches 1,000W, and only BLUETTI publishes a noise rating at all.
rated cycles
One card here has a consequence you can feel. The AC70 doubles from 1,000W continuous to a 2,000W surge. The Yeti goes 600W to 1,000W, a smaller multiple on a smaller base. Both clear the peak draw of every scenario modeled on this page, so nobody's compressor is refusing to start. What the AC70 has is margin, and margin is what you spend on the load you did not plan for.
The rest mostly cancels: same warranty term, same USB-C ceiling, same handoff speed when the power goes. The one card that does not cancel is noise, and it does not cancel because only one of the two brands filled it in.

Scenario math and per-appliance runtimes, modeled from the spec record.
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
Neither unit covers this scenario's 2,100Wh: the AC70 comes up 1,447Wh short (about 31% covered), the Yeti 700 1,525Wh (27%). Treat this as partial cover — enough for the essentials in it, not the whole list.
Battery budget usedlower = more headroom
LOAD Phone Charger 15W×6h · LED Lights 40W×8h · Box Fan 75W×14h · CPAP Machine 40W×16h
SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
Neither box finishes this one, and the gap is too wide to argue about. Eight hours of these loads wants 1,645Wh, and the AC70 can usefully deliver well under half of that. The Yeti delivers less again. Both can start everything on the list, which is the frustrating part: they empty out well short of morning and leave you in the dark holding a perfectly good inverter.
Battery budget usedlower = more headroom
LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Both finish this one and neither breaks a sweat. A 320Wh night is about half of what either can usefully deliver, so you wake with reserve whichever you own. The tiebreak is not capacity, it is the fan two feet from your head. BLUETTI rates the AC70 at 45dB under load; Goal Zero publishes no noise figure for the Yeti 700 at all. On the one night you are actually listening, take the number over the silence.
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
Neither unit
Neither unit covers this scenario's 910Wh: the AC70 comes up 257Wh short (about 72% covered), the Yeti 700 335Wh (63%). Either gets you most of the way, so this is a scenario you plan around rather than one you should rule them out for.
Battery budget usedlower = more headroom
LOAD Laptop 60W×8h · External Monitor 30W×8h · Router + Modem 20W×8h · Phone Charger 15W×2h
SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Neither unit
Neither one goes the distance, and on the AC70's side it is agonizing: 670Wh of party against 103% of what it can usefully deliver. It misses by a hair. The Yeti misses by more, at 116%, and it misses permanently, because the AC70 can bolt on an expansion battery and turn a near-thing into a comfortable one. Score it a loss for both, with only one of them holding a rematch.
Battery budget usedlower = more headroom
LOAD Blender 400W×0.5h · LED TV (55") 80W×4h · Bluetooth Speaker 15W×4h · Phone Charger (×3) 45W×2h
SCN-06 · 24 hours · needs 4,685Wh
Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit covers this scenario's 4,685Wh: the AC70 comes up 4,032Wh short (about 14% covered), the Yeti 700 4,110Wh (12%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Conclusion
August 2, 2026
Verdict: the AC70
Take the AC70. It holds 91Wh more, runs a 1,000W inverter against 600W, accepts 500W of solar to the Yeti's 200W, can add expansion batteries later, and costs $341 less — and the cheaper unit is also the cheaper energy across the full life of the cells, at 16 cents a lifetime kilowatt-hour against 26. Goal Zero's 4,000-cycle rating and its 3.2-pound weight saving are both genuine, and neither is worth close to double the price unless you are carrying the unit a real distance on foot. One caveat worth taking seriously before you buy: BLUETTI's customer support is the most inconsistent in this category, and buying direct from BLUETTI rather than through a marketplace reliably produces better claim outcomes. That single choice is what de-risks this pick.

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, AC70 rates 4.8/5 (89th percentile of 20 Compact-class units), and Yeti 700 rates 3.6/5 (16th percentile of 20 Compact-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.
AC70: 45dB Published
45dB is about as loud as a running refrigerator. It is BLUETTI's own rating rather than a reading on a shared bench — makers differ on whether they quote a best case or a figure under load, so treat it as a starting point rather than what you would hear at a bedside. For most people, fan noise around 45dB and up is where sleep starts to suffer.
2x surge, and what it is actually for
The AC70 doubles its 1,000W continuous rating to 2,000W on startup surge. The Yeti 700 goes from 600W to 1,000W, a smaller multiple. Both clear the peak draw of every scenario modeled on this page, so this is not about whether your fridge starts today. It is about the appliance you plug in next year without checking the label first.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The AC70's figure is a maximum rather than a guarantee — it depends on buying direct from BLUETTI or registering the unit, since reseller purchases carry a shorter term. Worth saying because the per-dollar framing can suggest otherwise: the AC70 works out at 13.9 years of cover per $1,000 spent against the Yeti 700's 7.1, but that spread is the price gap, not the terms.
Where the Yeti actually wins
4,000 cycles against 3,000 is a genuine advantage and it belongs to Goal Zero. On weekend use that is 38.5 years of battery against 28.8, both so far past the five-year warranty that the number stops being a purchasing input and becomes a curiosity. Longevity is the Yeti's best card, and it still is not enough to carry the price.
No published noise number for the Yeti 700
You cannot compare a rating that does not exist. The AC70 arrives with 45dB under load printed on the sheet; the Yeti 700 arrives with nothing, so your first honest data point is the night you are trying to sleep beside it. That is not an accusation of loudness. It is a decision you are being asked to make blind, on the one spec you will never return a unit over.

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. LFP across the rest of the range, though rated cycle life spans 2,500 (EB3A) to 6,000, and it varies WITHIN the Elite range rather than tracking it — the Elite 300 and Elite 200 V2 are rated 6,000 while the Elite 30 V2, Elite 10 Mini, Elite 320 and Elite 400 are rated 3,000+ and the Elite 100 V2 4,000+, so check the specific model. Dual-voltage (120V/240V) in flagships.
Worth knowing
BLUETTI's support is the real risk inside this recommendation. It is email-driven with China-timezone delays, and outcomes range from efficient to weeks of runaround, with some owners offered a discount on a new unit instead of a repair. Buying direct from BLUETTI rather than through a third party measurably improves how a claim goes, and on a unit at this price that is the one piece of process worth getting right.
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
Goal Zero is a US company out of Salt Lake City, and that used to be the entire premium-price argument. It is weaker now: 2025-2026 reports describe long waits and tickets going unanswered for weeks, and the official community forums were shut down. The heritage is genuine. The service that justified the markup is not what it was.
Analyst note
Neither brand is a reason to pick the other one. BLUETTI brings the broader lineup, the better-rated app and support that is a coin flip. Goal Zero brings a US company, rugged design and support that no longer clearly outperforms it. If you were hoping the brand column would break this tie for you, it does not. Go back to the price and the specs.
Growth path
AC70
FIXED CAPACITYFixed at 768Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 500W of solar. Suitable for a 1-2 panel setup.
Adequate ports for most setups, but heavy users may want a power strip.
Yeti 700
FIXED CAPACITYFixed at 677Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 200W of solar. Limited to a single portable panel.
Adequate ports for most setups, but heavy users may want a power strip.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Neither expands, and that's no knock on either — each is a complete unit at a fixed size. Buy the capacity that covers your needs now (the AC70 gives you the larger ceiling); you can't add to either later.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
BLUETTI AC70
Coverage of the AC70 is broad and consistently positive, and the praise clusters on speed and size. Turbo mode refills it in under an hour, and pass-through works cleanly enough that you can charge from AC, solar or the car while it is powering somethingA2. At roughly 22 pounds it reads as a carry-it-anywhere unit that still runs a day of devicesA4. Testing turned up no faults, and the warranty runs three years standard with an automatic two-year extension when you buy direct, for five years totalA3.
The one recurring caveat is the fan. Quiet at light draw, clearly audible once you push the output, described as an old laptop or a gaming PC working hardA1. Nobody calls it intrusive. It is simply the sound the unit makes when it is earning its keep.
“Under light loads the fan is quiet, but push past heavier output and it ramps up to a noticeable but not obnoxious level — comparable to an old laptop or gaming PC under load.”

Goal Zero Yeti 700
The Yeti 700's record is thinner and reads more like product documentation than long-term ownership. What exists is consistent: sixth-generation LiFePO4 chemistry rated past 4,000 cycles, which Goal Zero frames as a decade-plus of daily useB1B4, an IPX4 case that handles temperature extremesB2, and a reviewer read of it as light and simple rather than powerful, aimed at quick tripsB3.
What is missing is anyone reporting back from year three with oneB1B3. Treat the durability claims as engineering specification rather than field-proven, and weight the parts of this comparison you can verify yourself accordingly.
“A 6th-generation 677Wh compact power station on upgraded LiFePO4 chemistry rated for 4,000+ cycles — daily use for over 10 years.”

Who Should Buy Which
Buy the AC70 if you…
- →You are buying your first power station and want the most capable box for the money: 768Wh, a 1,000W inverter and a 2,000W surge, for $359.
- →You camp with a solar panel. The AC70 takes 500W of input to the Yeti's 200W, and that is the spec that decides whether day two starts full.
- →You suspect your load list is going to grow. It is the only one of the two that can add capacity without a second full purchase.
- →You want a published noise figure before the thing shares a room with you overnight.
Buy the Yeti 700 if you…
- →You carry it on your body for real distances. 19.3 lb is the only advantage in this matchup that money genuinely cannot undo.
- →It lives outside. The IPX4 rating and the extreme-temperature tolerance are on the Yeti's sheet and not the AC70'sB2.

If neither fits
If your real load list looks like the bigger scenarios on this page — 2,100Wh for a weekend of camping, 4,685Wh for a day of van living — neither of these is your unit, and no panel fixes a battery this small. Both are one-night boxes. Buy something two to three times this size once, instead of buying one of these and then buying again.
The Bottom Line
Take the AC70. It holds more, pushes more, refills from the sun in a fraction of the time, costs less to own across the entire life of the cells, and it is the only one of the two that can get bigger later. Goal Zero's reply is 3.2 pounds and a weather-rated case, and that reply costs $341.
The specs buyers assume will separate these two are the ones that tie: same warranty term, same USB-C ceiling, same 20ms handoff when the power goes. Strip the ties out and what remains is one box doing more for roughly half the money. If you are hiking it in, buy the Yeti and enjoy the lighter arm. Everyone else, this is settled.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Goal Zero Yeti 700 worth nearly twice the price of the BLUETTI AC70?
Not unless weight decides your purchase. For $341 more the Yeti gives you 3.2 fewer pounds, a 4,000-cycle rating instead of 3,000, and an IPX4 case built to take weather. It gives up 91Wh of capacity, 400W of continuous output, 1,000W of surge and 300W of solar input to do it. If you carry the unit any real distance, the weight is a fair reason to pay; otherwise the AC70 is both the better machine and the cheaper one.
Which one is the better backup for a home office?
The AC70, though not because of the switchover. Both hand off to battery in 20ms when the grid drops, so that spec is a dead heat and should not factor into your choice. The AC70 wins on what it can hold up once it is running: a 1,000W inverter and 768Wh against 600W and 677Wh, which is the difference between covering a desk and covering a desk plus whatever else shares that circuit.
Will either one run my CPAP all night?
Both will, comfortably. A 320Wh night is around half of what either can usefully deliver, so capacity is not the question here. The question is fan noise two feet from your head, and only BLUETTI publishes a figure: 45dB under load on the AC70, nothing at all on the Yeti 700. If the unit is sleeping in your bedroom, take the number you can actually check.
Can either one get me through an 8-hour blackout?
No, and it is not close for either one. The eight-hour load list here wants 1,645Wh, which is more than double what the AC70 can usefully deliver and further still beyond the Yeti. Both units can start everything on that list, so peak draw is not the failure mode; they simply run out of stored energy partway through. If riding out outages is why you are shopping, buy something two to three times this size rather than picking between these two.
Can I add more capacity to either one later?
Only to the AC70. It accepts BLUETTI expansion batteries, so 768Wh is a starting point rather than a ceiling. The Yeti 700 is sealed at 677Wh and always will be, which makes its upgrade path a second unit at full price. If you are at all unsure whether this size is enough for you, that difference matters more than any single spec on the page.
