Head-to-head test
BLUETTI AC70 vs Goal Zero Yeti 500
The Yeti 500 costs $141 more than the Bluetti AC70 and gives you less of nearly everything: less capacity, half the output, slower solar, and even less lifetime energy despite its higher cycle count.

Spec deltas
Spend less and get more of almost everything — that's the Bluetti AC70 against the Goal Zero Yeti 500. At $359 the AC70 brings 768Wh, a 1,000W inverter, and up to 500W of solar input. The Yeti 500 asks $500 for 499Wh, a 500W inverter, and a 200W solar ceiling. The cheaper box is the bigger one.
The Yeti has two honest advantages, and you should know them before the verdict lands. It's lighter — 16.1 pounds to the AC70's 22.5, a real difference if you carry it any distance. And it's rated for 4,000 charge cycles against 3,000. That second number looks like the Yeti's trump card. It isn't, and the lifetime-energy math is where it comes apart.
Take the AC70. It's cheaper to buy, cheaper per lifetime kilowatt-hour, and it out-specs the Yeti on capacity, output, and solar. The Yeti 500 earns a look only if its lighter body genuinely decides your purchase, or if you're buying into Goal Zero's US-based, cooler-and-kit ecosystem on purpose. For the spec sheet alone, it's the pricier way to get less.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
3,000 cycles of 768Wh beats 4,000 cycles of 499Wh — 2,304 kWh against 1,996 kWh over the rated life. The AC70 delivers about 308 more kilowatt-hours across its lifetime while costing less up front. The Yeti's headline durability spec is the rare one pointing the wrong way.
Yeti 500 rated for 4,000 cycles; AC70 for 3,000A Yeti 500 cycle is 499Wh; an AC70 cycle is 768WhLifetime energy: 1,996 kWh (Yeti) vs 2,304 kWh (AC70)
Why it mattersIf you were leaning Yeti because 4,000 cycles sounds like the longer-lived unit, that's the exact reasoning this pairing punishes: the cheaper AC70 is the one that lasts, measured in energy delivered.
cost / lifetime kWh
The Yeti's energy also costs more to own: $0.25 per lifetime kilowatt-hour against $0.16, about 56% more. So the premium buys a smaller, weaker box that then charges you more per watt-hour for the rest of its life. Whatever justifies the Yeti's price, it isn't on the spec sheet.
AC70 $359; Yeti 500 $500AC70 768Wh / 1,000W; Yeti 500 499Wh / 500WCost per lifetime kWh: $0.16 (AC70) vs $0.25 (Yeti 500)
Why it mattersBuyers who assume costs-more-must-be-more should flip the default here: start from the AC70 and make the Yeti prove its case on weight or brand.
weight
Per watt-hour, the AC70 is actually the denser pack — 34 Wh/lb to the Yeti's 31 — so the weight gap is less battery, not better engineering. The Yeti wins the bathroom-scale test in absolute pounds; the AC70 wins the energy-you-can-carry test.
Yeti 500 weighs 16.1 lbs; AC70 weighs 22.5 lbsAC70 holds 768Wh; Yeti 500 holds 499WhEnergy density: 34 Wh/lb (AC70) vs 31 Wh/lb (Yeti 500)
Why it mattersIf you truly carry it far and don't need the extra capacity, the Yeti's 6.4 pounds are worth it. If you just want it light for its size, the AC70 already is.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The cheapest unit to buy is also the cheapest to own — $0.16 vs $0.25 per lifetime kilowatt-hour — and the cycle-life spec that seems to favor the Yeti actually doesn't.
cost / lifetime kWh
The AC70 is cheaper to buy and cheaper to keep. It works out to $0.16 per lifetime kilowatt-hour against the Yeti 500's $0.25 — the Yeti's energy costs about half again as much across the years you own it. That's the price gap compounding: you paid more up front for a smaller battery, and every kilowatt-hour you pull out afterward carries that premium.
The counterintuitive part lives in the cycle numbers, and it's worth slowing down for. The Yeti is rated for more charge cycles, which reads like the longer-lived unit — but a cycle only means as much as the battery behind it, and the AC70's is bigger. Fewer, larger cycles win the lifetime-energy math outright. The durability spec people reach for Goal Zero to get is, on this pairing, working against them.
PowerScore Breakdown
Selected because: Capacity, output, surge, and solar input all favor the AC70 (768Wh and 1,000W vs 499Wh and 500W), and this is where that gap adds up.
overall power score
Every spec that describes how much work the unit can do lands with the AC70. It holds 768Wh to the Yeti's 499, and inverts at 1,000W to the Yeti's 500 — which means anything drawing between 500 and 1,000 watts runs on the AC70 and simply won't start on the Yeti. Surge headroom follows the same split, 2,000W against 1,000. The composite power score, 2,507 to 1,727, is those gaps added together.
Solar is the quiet one. The AC70 takes up to 500W of panels; the Yeti caps at 200W. On paper a full 768Wh refill at 500W is a bit over an hour and a half of ideal sun, while the Yeti needs roughly two and a half hours to refill less — and real sun is never ideal, so both stretch. In an outage where you recharge every day, the wider input is the difference between a morning chore and an all-day one.
Portability & Form Factor
Selected because: The Yeti 500's one clear win — 16.1 lbs against 22.5 — and the section that decides how much it's worth to you.
weight
16.1 pounds you carry one-handed; 22.5 you carry with both, or set down sooner than you meant to. That 6.4-pound gap is the Yeti 500's clearest advantage, and it's a real one — for the person walking gear to a backcountry site or lowering it into a boat, weight is the spec they feel on every single trip.
It stops mattering the moment the unit lives in one place. In a garage, a closet, a truck bed, or on the nightstand next to a CPAP, that saving is just a number on a page, and everything the AC70 gives you for it — more capacity, more output, faster solar — is on the table every day. Buy the Yeti for its weight only if you'll actually be holding it.
Your Life, Your Pick
Selected because: Both are compact units; this shows which real-world loads each actually covers, and where the AC70's larger tank pulls ahead.
These are both compact units, and the scenario table is honest about it: the big days — a full weekend's 2,100Wh, a realistic van-life 4,685Wh — are beyond both, and no verdict here pretends otherwise. What the table shows is subtler. Wherever the load is small enough to matter, the AC70 covers more of it, because it starts with 653 usable watt-hours to the Yeti's 424.
The one scenario both fully cover is the one closest to home for a lot of buyers: a CPAP. At about 40W it barely touches either unit — the AC70 finishes the night with 333Wh unused, the Yeti with 104Wh — so capacity is a non-issue and the decision moves to noise and weight. Everywhere the load climbs from there, the extra 229 usable watt-hours in the AC70 is simply more evenings before you're hunting for a wall socket.
Brand Trust
Selected because: The Yeti's price leans on Goal Zero's premium-brand promise, so it's worth checking how well that promise still holds.
The Yeti's price has always leaned on a brand promise: American company, premium support, buy-it-for-life heritage. Goal Zero pioneered this category and still builds rugged, US-designed hardware with a real ecosystem of coolers, panels, and vehicle kits around it. That part is true, and it's worth something to the right buyer.
But the premium-support half of that promise is the part fading fastest. Through 2025 and 2026 the picture is long waits and unanswered tickets, and Goal Zero shuttered its official community forums. BLUETTI's support is genuinely inconsistent too — email-based, often on China time — but it never charged you a premium to justify. If you're paying more for the Yeti expecting white-glove service, make sure that's still what the money buys before it decides your purchase.

Neither unit
Neither unit covers this scenario's 2,100Wh: the AC70 comes up 1,447Wh short (about 31% covered), the Yeti 500 1,676Wh (20%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

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 500 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.

Game day power for the crew
Neither unit
670Wh is a near-miss for one unit and a real miss for the other. The AC70 stops 17 watt-hours short — skip a single phone top-up or accept a slightly shorter evening and you've covered it. The Yeti 500 lands 246 watt-hours short, closer to a third of the party missing. Neither finishes it on the spec sheet, but only one is asking you to trim a rounding error.

Conclusion
August 30, 2026
Verdict: the AC70
The AC70 wins on price ($359 to $500), capacity (768 to 499Wh), output (1,000 to 500W), solar input (500 to 200W), and cost per lifetime kilowatt-hour ($0.16 to $0.25) — and because its 3,000 cycles move a bigger battery, it also delivers more total lifetime energy than the Yeti's 4,000. The Yeti 500 is genuinely lighter (16.1 vs 22.5 lbs) and carries Goal Zero's US-brand heritage and ecosystem, so the buyer who hauls it far or already lives in that ecosystem has a real case. Everyone else pays more for less. Buy the AC70.

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 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.
The Fan Is the AC70's One Tell
45dB under load — about a running refrigerator. Quiet when it's sipping power, clearly present once you push it. That's the honest catch on the unit we're recommending: park it in a bedroom and you'll hear it work. A light load like a CPAP sits closer to the quiet end, but if silence is the whole point, this is the AC70's one soft spot.
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 500's 10, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The Yeti 500 is rated for 4,000 cycles vs 3,000. In real life: at daily use, that's 11 vs 8.2 years. At weekend use (twice a week), it's 38 vs 29 years. One caution reading years across different sizes: a cycle is 499Wh on the Yeti 500 and 768Wh on the AC70, so count lifetime energy — roughly 1,996 kWh against 2,304 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.
Yeti 500: Noise Level Not Disclosed
The AC70 publishes its noise level (45dB); the Yeti 500 doesn't publish one. That isn't evidence the Yeti 500 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 AC70's 45dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the Yeti 500 before deciding.

Analyst note
The AC70 wins on both sticker price and long-term value. At $0.16/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. 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 AC70 still delivers more over its shorter horizon (2,304 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 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
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 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
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

Goal Zero Yeti 500
Field data on the Yeti 500 is thinner — the LFP version is new, and much of the coverage leans on its headline 4,000-cycle rating and its use as outage backupB0B1. One 2026 long-term reviewer logged more than 180 charge/discharge cycles with minimal degradation, a promising early signal but still earlyB4.
Two cautions. First, the model name is a trap: this LFP Yeti 500 (4,000 cycles) is a different battery from the older NMC Yeti 500X (about 500 cycles), and some listings still conflate themB0. Second, Goal Zero's claim that it will run a full-size fridge for up to six hours comes from Goal Zero's own site, not independent testing — useful as a ballpark, not proofB2.
“The Yeti 500's LiFePO4 battery is rated for 4,000+ cycles, meaning daily use for over 10 years (to 80% capacity at 75F).”

Who Should Buy Which
Buy the AC70 if you…
- →The value-first buyer who wants the most watt-hours and watts per dollar: 768Wh and a 1,000W inverter for $359 is the better hardware deal on this page.
- →The blackout-prep household running a fridge, a router, and phones in shifts — the AC70's 653 usable watt-hours and 500W solar input outlast and refill faster through a daytime outage.
- →Anyone who might run a load between 500 and 1,000 watts — a mid-size power tool, a countertop appliance, a space heater on low — that the Yeti's 500W inverter can't start at all.
Buy the Yeti 500 if you…
- →The person who carries their power station rather than just moving it: 16.1 pounds against 22.5 is a real saving on a long walk to a campsite or into a kayak, if you don't need the extra output.

Anyone whose real load looks like the big scenarios here — a full camping weekend (2,100Wh), a long blackout (1,645Wh), or a van-life day (4,685Wh). Both units cover only a fraction of those. The right buy is a much larger station sized to the 1,645Wh-and-up these days actually demand, not the cheaper of two boxes that are both too small.
The Bottom Line
The AC70 is the cheaper unit and the better one — an unusual combination that makes this an easy call. You pay less up front and get more capacity, more output, faster solar refills, and a lower cost per lifetime kilowatt-hour. The Yeti 500's higher cycle count is the one spec that seems to argue back, and it's the one that falls apart on inspection: more cycles of a smaller battery still add up to less energy than the AC70 delivers over its life.
Buy the Yeti 500 if the 6.4-pound weight saving genuinely changes how you'll use it, or if you're committing to Goal Zero's ecosystem with eyes open. For everyone else, the AC70 is more power station for less money, and the rest of this page is a footnote to that.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Goal Zero Yeti 500 worth the extra money over the Bluetti AC70?
On the spec sheet, no. The AC70 costs about $141 less and gives you more capacity (768 vs 499Wh), double the output (1,000 vs 500W), and faster solar input (500 vs 200W). The Yeti 500's real arguments are its lighter 16.1-pound body and Goal Zero's US-based brand and ecosystem, not its performance.
The Yeti 500 has more charge cycles — doesn't that mean it lasts longer?
Not in the way that matters. The Yeti is rated for 4,000 cycles to the AC70's 3,000, but a cycle is only as big as the battery behind it: 4,000 cycles of 499Wh is 1,996 kWh of lifetime energy, while 3,000 cycles of 768Wh is 2,304 kWh. The AC70 delivers more total energy over its life despite the lower cycle number. And neither battery dies at its limit — both settle to about 80% capacity and keep going.
Can either of these run a refrigerator during a power outage?
For a while, yes. Both can start a typical fridge — surge headroom isn't the problem — but capacity is: the AC70's 653 usable watt-hours will outlast the Yeti 500's 424 on the same fridge. Goal Zero cites up to six hours running a full-size fridge on the Yeti, which is a manufacturer figure rather than a tested one. Neither is an all-night or whole-home solution; for that you want a much larger station.
Which is quieter for a CPAP or a bedroom?
Impossible to say cleanly, because only one of them tells you. The AC70 lists 45dB under load — about a running fridge, and a spec-sheet best case rather than a measurement. The Yeti 500 publishes no noise figure at all. At a CPAP's roughly 40W draw both have enormous headroom (the AC70 keeps 333Wh in reserve, the Yeti 104Wh), so capacity is irrelevant and the whole question is fan behavior — which you can't compare when one side is blank. If a silent bedroom is the priority, find a hands-on noise test of the Yeti before you commit.
I want one for van life or a long outage — which should I get?
Probably neither, if you're honest about the load. A van-life day runs roughly 4,685Wh and a long blackout around 1,645Wh; these units deliver 653 (AC70) and 424 (Yeti) usable watt-hours, so you'd cover a fraction and spend the outage rationing. Buy a larger station sized to the job. If your real need is a weekend of light devices or a CPAP, the AC70 is the better-value pick of these two.
