Head-to-head test
BLUETTI AC200L vs Goal Zero Yeti 500
The axis is whether you're buying a box to carry or a load to cover: the Yeti 500 goes in one hand, and the AC200L is the only one of the two still running at hour eight of a blackout.

Spec deltas
The AC200L holds four times the battery for $399 more, and the bigger pack is also the cheaper energy to own. That is 2,048Wh against 499Wh, $899 against $500. It reads like the extravagant answer, and it isn't.
What the Yeti 500 actually sells you is a 16.1 lb box that goes in one hand. The AC200L is 62.4 lbs, which is both arms, bent knees, and a bad idea on basement stairs. That 46.3 lb gap is the only thing here capable of reversing the call, and for one kind of buyer it does.
Of the six load profiles we run, the Yeti 500 finishes exactly one: a CPAP night, spending 75% of its usable energy to do it. The AC200L finishes four, including the eight-hour blackout, and comes up short on the same two the Yeti 500 misses by a mile. Take the AC200L unless you're buying for that one night, or you're the one carrying it.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
solar input
Which means the spec that decides a real outage isn't capacity, it's refill. 2,048Wh against 1,200W of panel input is under two hours of good sun on paper; 499Wh against 200W is about two and a half. The AC200L can be back to full before lunch on day two, while the Yeti 500 spends most of a morning putting back 499Wh that wouldn't have covered last night either.
The 8-hour blackout profile needs 1,645Wh; the AC200L has 1,741Wh usable and finishes with 96Wh to spareThe Yeti 500 has 424Wh usable and ends that same night 1,221Wh shortAC200L solar input: 1,200W. Yeti 500 solar input: 200W
Why it mattersIf you're buying for storms rather than trips, weigh the charge input as heavily as the pack, because an outage doesn't schedule itself around your panels.
weight
So you can't buy your way out of the weight problem inside this pair. The heavy unit doesn't finish the camping weekend either, and the fix for that is more battery still, which means more pounds and not fewer. The weight gap only earns its keep if what you need lands between 424Wh and 1,741Wh of usable energy, which is exactly where the blackout, the workday and the tailgate sit and exactly where the camping weekend doesn't.
AC200L: 62.4 lbs for 2,048Wh. Yeti 500: 16.1 lbs for 499WhThe weekend camping profile needs 2,100Wh; the AC200L has 1,741Wh usable and comes up 359Wh shortThe Yeti 500 has 424Wh usable, about a fifth of that weekend
Why it mattersIf you're shopping this pair for multi-day camping, you're shopping a size up, not sideways.
cost / lifetime kWh
Priced over everything each pack will ever deliver, the cheaper box is the expensive energy. The Yeti 500 costs roughly two thirds more per kilowatt-hour across its rated life, and the extra thousand cycles never claw that back, because each one of them is a quarter the size.
Yeti 500: 4,000 rated cycles, and a cycle is 499Wh. AC200L: 3,000 rated cycles, and a cycle is 2,048Wh$899 for the AC200L against $500 for the Yeti 500Cost across the rated life: $0.15 per kilowatt-hour for the AC200L, $0.25 for the Yeti 500
Why it mattersIf you're using cycle counts to decide this, check what a cycle is worth on each unit before you trust the column.
continuous output
The Yeti 500 doesn't fail by refusing to start things. It fails by starting them and then running out, which is the worse of the two failures because you find out at the end of the afternoon rather than the beginning. The AC200L's 3,600W ceiling is insurance for the loads that aren't on this page: the well pump, the circular saw, the compressor whose switch-on draw is a number of watts and not a multiple of anyone's inverter rating.
AC200L: 2,400W continuous and 3,600W surge. Yeti 500: 500W continuous and 1,000W surgeAcross all six load profiles, both units start and hold every peak; the biggest is the tailgate's 400WThe Yeti 500 runs 246Wh short of the 670Wh tailgate and 1,221Wh short of the 1,645Wh blackout
Why it mattersIf you've been comparing surge ratios, stop and compare watt-hours against your actual afternoon instead.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: The Yeti 500 finishes one of the six load profiles below; the AC200L finishes four.
One night is where the Yeti 500 lives. A CPAP at about 40W for eight hours is 320Wh, and the Yeti covers it with 104Wh left over. That's enough headroom for a phone, not enough for a phone and a lamp and the bad-sleep wake-up where you go looking for something to plug in. The AC200L finishes the same night having spent 18% of itself.
Everything larger than that night breaks the tie hard, and the interesting part is watching where the AC200L breaks too. It clears the workday with 831Wh in hand and the tailgate with 1,071Wh, then misses the camping weekend by 359Wh, which is the frustrating kind of miss: close enough that you'd try it, short enough that you'd be rationing by Sunday morning. Two of these six rows aren't a choice between these units at all.
Portability & Form Factor
Selected because: 46.3 lbs separates these two units, and it is the only gap capable of reversing the verdict.
weight
Sixteen pounds goes in one hand, over a tailgate, up a ladder into a roof tent, and that is the entire case for the Yeti 500. It's a better case than the spec gap makes it look, because weight is the one comparison you feel every single time rather than once a year. 62.4 lbs is a planned route and a clear floor, and one lower-confidence review calls repositioning awkward at that weight with no wheels to helpA17.
The question isn't which is easier to lift, it's how often you'll lift it. A unit that lives on a shelf in the garage until the power goes out gets carried twice a year, and 62.4 lbs twice a year is a non-event. A unit that goes in and out of a truck every weekend gets carried a hundred times, and then the lighter box wins on the only axis it can win on.
Lifetime Value
Selected because: The cheaper unit to buy is the more expensive energy to own, and the cycle counts hide it.
cost / lifetime kWh
Cycle counts are the trap here, and the Yeti 500 wins the count. 4,000 rated cycles against 3,000 reads like the longer-lived unit, and by the calendar it is: at daily use, 11 years against 8.2. At weekend use, both numbers run past any sane ownership horizon. Then you remember that a cycle isn't a unit of time, it's a unit of energy, and it's four times bigger on one of these units than the other.
Cycle limits also aren't cliffs. Both packs are rated to the point where they've faded to roughly 80% of original capacity, and a pack at 80% is still a pack. Whichever you buy, what ends its service life will almost certainly be your needs changing rather than the cells giving up.
What the Specs Don't Tell You
Selected because: Seven cards fire on this pair, and two of them land on the unit we recommend.
rated cycles
A compressor doesn't care about ratios. The Yeti 500 keeps twice its continuous rating in reserve against the AC200L's one and a half, which is the better-engineered number and the less useful one, because a motor draws a quantity of watts at switch-on rather than a multiple of somebody's inverter rating. On this pair the ratio and the ceiling point in opposite directions, and the ceiling is the one that decides whether a thing starts.
The warranty pair looks like a dead tie and carries one asymmetry. Both units are five years. The AC200L's five is a maximum that depends on buying direct from BLUETTI or registering the unit, and a reseller purchase carries a shorter term; Goal Zero's five is just five. That isn't a reason to switch units. It's a reason to buy the BLUETTI from BLUETTI and spend the two minutes registering it. The two noise cards are the ones to read slowly: they look like a gap between the units and they aren't one.
Brand Trust
Selected because: A cross-brand pairing where the support record is the one column our pick loses.
BLUETTI's support is the reason to buy this unit from BLUETTI. It's email-first and timezone-delayed, and the bad outcomes are genuinely bad: owners describe support loops where the fix offered is the thing they already tried, or a discount on a new unit in place of a repairA2A3. Buying direct improves the odds and is also how you get the full warranty term, so both arguments push the same way here. That's the honest cost of our pick, and it's a real one.
Goal Zero's answer to all of that used to be that it's a US company in Salt Lake City with premium service. That's the part that's worn thin: email waits run long, tickets can sit for weeks, and the official community forums were shut, which took the peer-support fallback with them. Neither of these is a brand you buy for the phone call. Buy the hardware you're least likely to need to call about, from a seller with a real return window, and register it the day it lands.

Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Nobody wins this one. A 2,100Wh weekend is 359Wh more than the AC200L has to give, which is the frustrating kind of miss: close enough that you'd try it, short enough that you'd be rationing by Sunday morning. The Yeti 500 isn't in the conversation with 424Wh usable. If this row is your actual use, the answer is a bigger station rather than the better of these two.

8-Hour Blackout
Keep the essentials running through a night without power
AC200L
The AC200L reaches morning with 96Wh left, which is a pass and not a cushion. That's why the number to look at here isn't capacity, it's refill: the AC200L takes six times the solar input, and day two is the part of an outage nobody plans for. The Yeti 500 doesn't reach the end of night one, stopping 1,221Wh short.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Both finish the night, so capacity decides nothing and the smaller unit is the smarter buy for this one job. The difference is what's left in the tank: the AC200L ends the night having used 18% of itself, the Yeti 500 having used 75%, so if the night also includes a lamp, a phone and a middle-of-the-night wake-up, the Yeti's 104Wh of headroom is the figure that matters. The other difference is the one nobody can settle, because you'll be sleeping an arm's length from a fan that Goal Zero publishes no figure for.

AC200L
The Yeti 500 doesn't finish — 424Wh usable against the 910Wh this needs leaves it 486Wh short, about 47% of the scenario covered. The AC200L covers it with 831Wh to spare.

AC200L
Both units start the 400W peak without complaint; only one keeps feeding it. The Yeti 500 runs 246Wh short of a 670Wh afternoon, which in practice is the blender working beautifully right up until the music stops. Five AC sockets against two settles the rest of it.

Neither unit covers this scenario's 4,685Wh: the AC200L comes up 2,944Wh short (about 37% covered), the Yeti 500 4,261Wh (9%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Conclusion
September 13, 2026
Verdict: the AC200L, on Power Score margin
Take the AC200L. It finishes four of the six load profiles we run to the Yeti 500's one, it swallows a startup spike a 1,000W ceiling would argue with, and it takes six times the solar input, which is what turns surviving one night into surviving a weekend without power. It also works out cheaper per kilowatt-hour over the pack's rated life despite the higher sticker, so the cycle count that flatters the Yeti 500 never turns into cheaper energy. Buy the Yeti 500 instead if the honest description of your needs is a CPAP, a laptop and phones, and you are the person carrying it: 16.1 lbs against 62.4 lbs is the one gap the AC200L cannot close, and at that size you are not paying for capacity you will never reach. Anyone whose shortlist has a fridge and a blackout in it should stop comparing and buy the BLUETTI.

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, AC200L rates 3.9/5 (36th percentile of 26 Large-class units), and Yeti 500 rates 4.5/5 (71st percentile of 22 Personal-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.
62.4 lbs against 16.1: the one card that can flip this
This is our pick's real weakness and it deserves saying plainly rather than in a footnote. 62.4 lbs is a two-hands, bent-knees lift and a genuinely bad idea on basement stairs, while the Yeti 500 goes over a tailgate in one hand without thinking about it. The thing to weigh isn't which is heavier, it's how often you'll lift it: twice a year from a garage shelf, 62.4 lbs is a non-event, and every weekend into a truck bed, it's the whole decision. If you'll be lifting more often than draining, buy the light one and ignore the rest of this page.
How to read the 50dB figure
50dB is a published spec rather than a measurement, and makers normally publish the best case, often a capped quiet mode or a light load. So treat it as the quiet end of the AC200L's range, not a description of the unit fast-charging in your bedroom. It also isn't half of a comparison, because the Yeti 500 publishes nothing to set it against. It's one data point about one unit.
Yeti 500: Fixed Capacity
The Yeti 500 is sealed at 499Wh — fine if that covers you, but it's the ceiling. By contrast the AC200L can add expansion batteries, though the first thing it has over the Yeti 500 is its own 2,048Wh base — expansion is the step after that, for the buyer who would outgrow 2,048Wh as well.
Surge Power: Ratio and Ceiling Disagree
The Yeti 500 holds the higher surge-to-continuous ratio (2× vs 1.5×), but the AC200L holds the higher absolute surge ceiling — 3,600W against 1,000W. These measure different things. The ratio says how much headroom an inverter keeps above its own rating; the ceiling says how big a startup spike it can actually swallow. A motor draws a number of watts at switch-on, not a multiple of someone else's rating, so on raw starting ability the AC200L is the stronger unit here — while the Yeti 500 is the one running further below its own limit at steady state.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The AC200L'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 Yeti 500 works out at 10 years of cover per $1,000 spent against the AC200L's 5.6, but that spread is the price gap, not the terms.
More cycles, less energy
The Yeti 500's 4,000 cycles beat the AC200L's 3,000, and by the calendar that's 11 years of daily use against 8.2. Then remember what a cycle is on each unit: 499Wh on one, 2,048Wh on the other, which works out to roughly 1,996 kWh of lifetime energy against 6,144. The longer-lived pack delivers about a third of the power. Neither figure is an expiry date, either. A pack at its rated cycle count has faded to roughly 80% of original capacity, which is still a working battery.
No figure for the Yeti 500, and no way around that
An absence isn't evidence. Goal Zero not publishing a noise number doesn't make the Yeti 500 loud and doesn't make it quiet. It means there's nothing to hold it to and no honest comparison to run, so any page that hands you a difference here has invented one. This matters for exactly one kind of buyer, and it's a buyer worth protecting: if the unit is going in a bedroom, beside a crib, or next to a CPAP, you're choosing between a number that at least exists and a unit you'd want to hear first. Borrow one, or buy where you can send it back.

Analyst note
The Yeti 500 is cheaper to buy, but the AC200L is cheaper to own. At $0.15/kWh over its lifetime vs $0.25/kWh, the AC200L's higher cycle life and capacity make each dollar go further over the years. One caution on the lifespan row: the Yeti 500 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the AC200L still delivers more over its shorter horizon (6,144 vs 1,996 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 weakest part of buying BLUETTI, and the honest cost of our pick here. It's email-first, it runs on a China timezone, and outcomes are wildly uneven: some tickets are handled cleanly, others turn into weeks of troubleshooting runarounds, confusing third-party claim processes, or an offer of a discount on a new unit in place of a repair. Buying direct measurably improves the odds, and it's also how you get the full warranty term, so both arguments point at the same checkout page.
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 per dollar in the category, and by some distance the widest lineup in it, from tiny units to sodium-ion cold-weather packs and balcony storage. Rated cycle life varies by individual model rather than by product family, so check the model rather than the range name.
Worth knowing
Older and discontinued models can become effectively unrepairable, since there's no spare-parts commitment across the whole lineup. Buy something current, buy it direct, and register it.
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
A US company in Salt Lake City, which used to be the answer to everything above. That's the part that's worn thin: email waits run long, tickets can sit for weeks, and the official community forums were shut, which took the peer-support fallback with them.
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
The brand that started this category, with the most ruggedized-feeling hardware on the shelf and a genuinely integrated kit around it: coolers, lights, panels, vehicle mounts. If you're already in that ecosystem, it stays worth something.
Worth knowing
The previous-generation X series is out of stock across Goal Zero's own store as of 13 September 2026, with some models listed only as open-box. That's a buying note rather than a verdict on the current line, and the Yeti 500 here is the newer LFP unit. It is, though, why a stray 500X listing is leftover stock of an older battery chemistry rather than a cheaper version of this one.
Analyst note
Neither of these is a brand you buy for the phone call. BLUETTI gives you more hardware for the money and service you may have to chase; Goal Zero gives you the category's original hardware and a US company whose service no longer matches its reputation. The practical move is identical either way: buy from a seller with a real return window, register the unit the day it arrives, and choose the hardware you're least likely to need help with.

Analyst note
The Yeti 500 is sealed at 499Wh, which is fine if that covers you. The AC200L starts at 2,048Wh and can grow beyond it with BLUETTI expansion batteries — real headroom the Yeti 500 doesn't have if your needs climb toward partial-home backup.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
BLUETTI AC200L
The AC200L's field record reads as a good machine with a bad app. Owners consistently run into connectivity trouble: a new unit that wouldn't join a home WiFi network, with support repeating steps already triedA2, an iOS app that drops its cloud session whenever the owner leaves the houseA3, and a four-month hands-on test whose biggest complaint was that monitoring means standing within Bluetooth range, which is exactly where you are not when an outage startsA14. One owner three days in couldn't get the AC200L to see a brand-new B230 expansion battery at allA4, which is worth knowing if expandability is part of why you're buying it. App-store reviews echo the same theme, though they can't be pinned to this modelA5.
Where it has been measured, it measures well. A reviewer clocked the wall-to-battery handoff at 13.1 milliseconds against a spec of no worse than 20msA7, recorded the fans at roughly 40dB on low and 48dB on high from three feetA8, and ran a full-size refrigerator for 32 hours from a full charge with 7% left in the tankA9. A separate bench test pulled 1.77kWh out of it in 49 minutes at 86.0% to 92.6% efficiencyA11, which is useful context for the flat 85% usable derate this site applies to every unit. There is no equivalent figure of any kind for the Yeti 500, published or measured, so treat all of that as facts about one unit rather than a comparisonB0.
The honest catch on the quiet claim: the fans cycle. One owner describes them running 25 seconds out of every 60 at idle, alongside a PV relay that clicks at sunrise and sunsetA1. Quiet under load and fidgety at rest is a real combination, and if you plan to sleep beside this unit it's the behaviour to listen for in the first week while you can still return it.

Goal Zero Yeti 500
Field evidence on the Yeti 500 is thin, and most of what exists traces back to Goal Zero's own materials rather than to people who've lived with oneB0. The one useful independent data point is a 2026 reviewer who put 180-plus charge and discharge cycles through it with minimal observed degradationB4. That's early, but it points the right way against a 4,000-cycle ratingB1. Goal Zero's claim of up to six hours of full-size-fridge backup is the manufacturer's ownB2, and six hours is not a night.
Two things to check before you buy, both from our own research rather than from ownersB0. First, the LFP Yeti 500 is not the Yeti 500X: the older X is an NMC pack rated around 500 cycles, and listings conflate the two. Second, nobody has characterised this unit's fan the way you'd want. There's no published figure and nothing in our files to stand in for one, so if it's going in a bedroom, buy it somewhere you can send it back.
“The Yeti 500's LiFePO4 battery is rated for 4,000+ cycles, meaning daily use for over 10 years (to 80% capacity at 75F).”

Recurring owner themes
- App/WiFi connectivity is a recurring pain point — owners report failed WiFi pairing, cloud disconnects, and no remote (non-Bluetooth) monitoring option. [AC200L · 4 entries]
- Fan/relay cycling behavior gets mixed reports: some owners flag frequent on/off cycling at idle/solar cutover, while a hands-on tester measured the fans as relatively quiet under load. [AC200L · 2 entries]
- UPS switchover is fast and reliable in practical tests, but reviewers note the 20ms spec (vs newer 10ms competitors) could risk flicker for very sensitive electronics. [AC200L · 2 entries]
- Independent runtime/capacity and cycle-health tests have generally matched or come close to the advertised 2048Wh rating and cycle-life claims. [AC200L · 3 entries]
- Weight and lack of wheels/accessory-integration quirks are recurring physical/practical gripes despite otherwise positive reception. [AC200L · 2 entries]
- High 4,000+ cycle LFP rating and outage-backup capability (including running a fridge for hours) are the standout points. [Yeti 500 · 2 entries]

Who Should Buy Which
Buy the AC200L if you…
- →You're prepping for the outage that outlasts one night. 1,645Wh of blackout is where the Yeti 500 stops and the AC200L keeps going, and six times the solar input is what makes day two survivable rather than theoretical.
- →The fridge is the thing you're actually protecting. A 3,600W surge ceiling starts a compressor without drama, and one hands-on test ran a full-size fridge for 32 hours on a chargeA9.
- →You work out of a truck bed or a half-built job site all day. The remote workday profile is 910Wh and the AC200L finishes it with 831Wh still in hand, which is the difference between using a power station and rationing one.
- →You want one box for the tailgate. Five AC sockets against two, and a 400W peak that neither unit struggles to start but only one has the energy to keep feeding.
Buy the Yeti 500 if you…
- →The whole job is a CPAP and a phone. 320Wh a night out of 424Wh usable means you wake up with 104Wh spare, and you carry the thing in one hand.
- →You lift it more often than you drain it. Roof tents, canoe portages, a fourth-floor walk-up: 16.1 lbs is the spec that decides this one, not watt-hours.
- →Nothing you own draws more than 500W and you know it. Laptop, lights, phones, a fan, a router. The Yeti 500 runs all of that and you'll never meet its ceiling.
- →You're replacing a tired Yeti 500X and want the LFP pack's 4,000 cycles this time aroundB0B1.
If neither fits
If your real list is a 2,100Wh camping weekend or a 4,685Wh day in a van, close this page. Neither unit finishes either one, and the fix isn't picking the better of two misses. Clearing 2,100Wh at the 85% derate takes more than 2,470Wh of nameplate capacity, and the van wants more than twice that again, so you're shopping a station above that mark, a station with a second battery beside it, or the AC200L plus expansion if you'd rather grow into the capacity than buy it all at once.
The Bottom Line
Take the AC200L. Four times the battery, four of six load profiles finished against one, and cheaper energy across the pack's rated life despite the higher sticker. The cycle count that flatters the Yeti 500 is counting 499Wh cycles against 2,048Wh ones, and no number of small cycles adds up to a big pack.
The Yeti 500's case is 16.1 lbs, and it's a real case rather than a consolation. If the honest description of your needs is one CPAP, one laptop and a box you can carry with one hand, buy it and don't let the rest of this page talk you out of it. Everyone else: register the BLUETTI the day it arrives, make peace with its appA2A3, and stop worrying about night two.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the BLUETTI AC200L worth $399 more than the Goal Zero Yeti 500?
If you'll ever need more than 424Wh in one sitting, yes. That's everything the Yeti 500 has to give after the 85% usable derate, and it's why it finishes one of our six load profiles while the AC200L finishes four. If your list genuinely stops at a CPAP and a laptop, the extra money buys capacity you will never reach and 46.3 lbs you'd rather not lift.
Will the Goal Zero Yeti 500 run a CPAP all night?
Yes. Call it 40W for eight hours, or 320Wh, against 424Wh of usable energy, so you finish the night with 104Wh spare. What nobody can tell you is how the fan behaves while it does it, because Goal Zero doesn't publish a noise figure for this unit and there's no hands-on report in our files to stand in for one. If it's sleeping next to your head, buy it somewhere with a return window.
Is the Yeti 500 the same thing as the Yeti 500X?
No, and the difference is large. The Yeti 500 is the LiFePO4 unit rated for 4,000 cycles; the 500X is the older NMC pack rated around 500, and listings do conflate the two. Goal Zero's own store has the entire previous-generation X series out of stock as of 13 September 2026, some of it open-box only, so a cheap 500X found elsewhere is leftover stock of a different unit rather than a bargain version of this one.
Can either of these keep a refrigerator running through a blackout?
The AC200L, comfortably. Its 3,600W surge ceiling starts a compressor without argument, and one hands-on test ran a full-size fridge for 32 hours from a full charge. The Yeti 500 is a several-hour bridge at best, with Goal Zero's own materials claiming up to six hours. Our eight-hour blackout profile needs 1,645Wh and leaves the Yeti 500 1,221Wh short of the morning.
Do both units really come with a 5-year warranty?
Both are listed at five years, with one condition attached. The AC200L's five is a maximum that depends on buying direct from BLUETTI or registering the unit, and a purchase through a reseller carries a shorter term. The Yeti 500's five years stand as published. Warranty length isn't a tiebreaker between these two, but it is a reason to buy the BLUETTI from BLUETTI and register it.
