Head-to-head test
Goal Zero Yeti 500 vs Goal Zero Yeti 700
Both Yetis surge to the exact same 1,000W ceiling, so the 700's extra continuous output and 178Wh come at $200 and 2.8 lbs, not at a stronger inverter.

Spec deltas
The Yeti 500 holds 499Wh for $499.95. The Yeti 700 holds 677Wh for $699.95. That's 178Wh more for $200 more — a straightforward capacity upgrade within the same family, not a different generation of hardware.
What doesn't change between them is more interesting than what does. Both are rated for 4,000 cycles, both carry a 5-year warranty, and both surge to the same 1,000W ceiling. The 700's higher continuous rating — 600W against 500W — is real, but it isn't backed by a bigger inverter ceiling, just a bigger everyday number.
This is closer to picking a size than picking a winner. The lifetime cost per kWh is within a penny either way, so the decision comes down to how much capacity and continuous output you actually use on a given night, not which one is the better-built battery.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Price
Relative to its own continuous rating, the Yeti 500 actually has more surge headroom — 1,000W over a 500W rating is a full 2x cushion, while the Yeti 700's 1,000W over 600W is a smaller 1.67x cushion. Fridge and AC compressors spike 2-3x their rated draw on startup, so the smaller unit has proportionally more room to absorb that spike before hitting the same wall.
Yeti 500 surges to 1,000WYeti 700 also surges to 1,000W
Why it mattersBuyers upgrading to the 700 specifically to start a bigger compressor load should know the surge ceiling didn't move — only the continuous rating and the price did.
cost / lifetime kWh
Both also work out to 11 years of daily use before hitting meaningful capacity loss, because that figure is driven by cycle count alone, not battery size — the 700's extra 178Wh doesn't buy it a longer life, just a bigger one.
Yeti 500: $499.95, 4,000 cycles, $0.25 per lifetime kWhYeti 700: $699.95, 4,000 cycles, $0.26 per lifetime kWh
Why it mattersThis isn't a value argument either way — decide on how much capacity and continuous output you actually need, not on which one lasts longer, because they last the same.
Capacity
That extra capacity shows up concretely overnight: running a CPAP, the 700 finishes with noticeably more of its tank untouched than the 500 does. If you're pairing a CPAP with anything else — a fan, a phone charger, a second device — that spare headroom is the 700's real argument.
Yeti 700 holds 677Wh against the Yeti 500's 499WhYeti 700 costs $200 more and weighs 2.8 lbs more
Why it mattersBuyers running more than one device overnight, or wanting real margin rather than a tight fit, should pay the $200 for the 700; a single-device overnight job doesn't need it.
The specific dimensions that decide these two units — everything else is a tie.
PowerScore Breakdown
Selected because: Both surge to the identical 1,000W ceiling — the more interesting number is the ratio to each unit's own continuous rating.
overall power score
Both units cap their surge at 1,000W, so a sudden compressor spike hits the same ceiling whichever one you own. What differs is the continuous rating underneath it — 500W for the Yeti 500, 600W for the Yeti 700 — which means the 500 actually has the wider cushion between its everyday output and its surge limit, not the 700. Paying more here buys sustained output, not a stronger inverter.
Lifetime Value
Selected because: Near-identical cost per lifetime kWh and identical years-of-daily-use make this close to a genuine ownership-cost tie.
cost / lifetime kWh
$0.25 per lifetime kWh for the Yeti 500, $0.26 for the Yeti 700 — as close to a coin flip as this metric gets. Both are also rated for 11 years of daily use before losing meaningful capacity, because that figure tracks cycle count, which is identical at 4,000 on both units, not capacity. The 700's $200 premium and 178Wh aren't buying a longer-lived battery; they're buying a bigger one.
Portability & Form Factor
Selected because: 178Wh, $200, and 2.8 lbs is the entire delta between these two — worth stating plainly in one place.
weight
The Yeti 700 weighs 19.3 lbs against the Yeti 500's 16.5 — 2.8 lbs more to lift for 178Wh more capacity and 100W more continuous output, at a $200 premium. None of that is a bad trade if you need the extra headroom regularly; all of it is money and weight spent on nothing if you don't.
Your Life, Your Pick
Selected because: CPAP Overnight is the one scenario with daylight between them, driven purely by the capacity gap.
Weekend Camping, the 8-Hour Blackout, Remote Workday, Tailgate Party, and Van Life Daily all defeat both units by a wide margin — the 178Wh gap between them doesn't change that outcome, so it's not worth paying for in those scenarios.
CPAP Overnight is the exception: the 700 finishes with real spare capacity where the 500 is working harder relative to its tank. Pairing a CPAP with a second device overnight is the concrete case where that extra headroom earns its $200.

Conclusion
July 14, 2026
Verdict: the Goal Zero Yeti 500
Default to the Yeti 500. Its lifetime cost per kWh is within a penny of the Yeti 700's ($0.25 vs $0.26), both are rated for exactly 4,000 cycles, and both work out to 11 years of daily use before losing meaningful capacity — cycle count drives that number, not battery size. The 700's entire case is 178Wh more capacity and 100W more continuous output for $200 and 2.8 lbs. That's a real reason to step up if you're running more than one device overnight or need sustained 600W output, and the 700 does win the modeled CPAP Overnight scenario on spare capacity. For a single typical overnight or daytime job, the 500 does the same thing for less.

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, Yeti 500 rates 4.7/5 (81st percentile of 22 Personal-class units), and Yeti 700 rates 3.6/5 (17th percentile of 19 Compact-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Same Surge Ceiling, Different Cushion
Both units cap out at 1,000W of surge power. Measured against each one's own continuous rating, the Yeti 500 actually has the bigger cushion — 2x its 500W rating, against the Yeti 700's 1.67x over its 600W rating. The bigger unit doesn't get a stronger inverter, just a higher everyday number.
Same Warranty Length, Different Yearly Cost
Both units carry a 5-year warranty, so the coverage itself is identical. Divide price by warranty length and the Yeti 500 costs $100 a year to the Yeti 700's $140 — the 700's premium shows up here too, not just on the sticker.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Goal Zero Yeti 500
Goal Zero frames the Yeti 500 as blackout insurance as much as a camping battery: plug in a full-size fridge during an outage and it'll run for about six hours before it's emptyA2. That's backed by a 4,000-plus cycle LiFePO4 rating, good for well over a decade of daily useA1. One 2026 long-term reviewer's early cycle testing hasn't shown meaningful degradation so far, encouraging for a battery this size being asked to do daily dutyA4. At roughly 16.5 lbs, it's the one you grab without thinking twice — the tradeoff is simply less capacity than its own bigger sibling.
“The Yeti 500's LiFePO4 battery is rated for 4,000+ cycles, meaning daily use for over 10 years (to 80% capacity at 75F).”

Goal Zero Yeti 700
The Yeti 700 is part of Goal Zero's 6th-generation LiFePO4 lineup, carrying the same 4,000-plus cycle rating as the Yeti 500B1B4 — the family's upgrade from the older NMC X-series shows up as reliability, not just a bigger number. It adds a rated water-resistance spec not present in the Yeti 500's own listing here, plus a build meant to handle temperature extremesB2. One reviewer's take is candid about the tradeoff: it's not the most powerful or capable unit in the lineup, just a light, simple one aimed at people who prioritize portability over raw outputB3 — a fair description of where it sits next to the 500, bigger, but still built for grab-and-go use.

Who Should Buy Which
Buy the Yeti 500 if you…
- →You want the cheaper, lighter unit and your typical draw is one device overnight — the ownership economics are essentially tied, so there's no cost penalty for choosing smaller.
- →You're buying primarily for grab-and-go portability and don't need more than 500W of continuous output.
Buy the Yeti 700 if you…
- →You're running more than one device overnight, or a CPAP alongside something else — the 700's extra headroom shows up concretely in that scenario.
- →You need 600W of sustained output rather than 500W; the surge ceiling is the same on both, but the continuous rating is where the 700 actually leads.
If neither fits
If your real need is a two-night camping trip (about 2,100Wh) or an 8-hour multi-appliance blackout (about 1,645Wh), both fall well short — look at a larger Yeti X-series or Alta unit instead of choosing between these two.
The Bottom Line
The Yeti 500 and Yeti 700 are closer to siblings than rivals: identical 4,000-cycle rating, identical 1,000W surge ceiling, and lifetime cost per kWh within a penny of each other. The entire gap is 178Wh, 100W of continuous output, $200, and 2.8 lbs.
Default to the Yeti 500 — there's no ownership-cost penalty for buying smaller. Pay the $200 for the 700 only if you actually need the extra capacity or continuous output on a regular night, not because a bigger number feels safer.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
What's actually different between the Yeti 500 and Yeti 700?
Capacity, continuous output, price, and weight. The 700 holds 677Wh against the 500's 499Wh, outputs 600W continuous against 500W, costs $200 more, and weighs 2.8 lbs more. Cycle life, warranty length, and surge ceiling — 4,000 cycles, 5 years, 1,000W — are identical on both.
Is the Yeti 700 worth $200 more than the Yeti 500?
Only if you regularly need the extra 178Wh or 100W of continuous output. The lifetime cost per kWh is nearly identical between them — $0.25 for the 500, $0.26 for the 700 — so you're not paying a premium for better economics, just for more capacity.
Does the bigger Yeti 700 have a stronger inverter?
No. Both units surge to the same 1,000W ceiling. The 500 actually has the wider cushion between its everyday 500W output and that ceiling — a full 2x — versus the 700's 1.67x, so a sudden compressor spike doesn't get any easier to handle on the bigger unit.
Which one lasts longer?
Neither — they're tied. Both are rated for 4,000 cycles and work out to 11 years of daily use before losing meaningful capacity, because that figure depends on cycle count, not battery size. The 700's extra capacity doesn't extend its lifespan.
Which should I buy?
Take the Yeti 500 by default — it's cheaper, lighter, and the ownership economics are essentially a tie with the 700. Step up to the 700 only if you're regularly running more than one device overnight or need 600W of sustained output rather than 500W.
