Spec deltas
Both carry the Goal Zero name, but they're built for different buyers. The Sherpa 100AC (95Wh, 100W) and the Yeti 700 (677Wh, 600W) come from different product lines with different engineering priorities and a $450 price gap. The Yeti 700 has a slight edge, but the margin is close enough that your use case should break the tie.
The Yeti 700 holds 582Wh more than the Sherpa 100AC — about 4 hours on a fridge against 1 — a real but modest edge that shows up mainly on longer outages. For camping, tailgating, or keeping devices charged, both have the headroom, so price, weight, and longevity lead the decision instead.
Pick the Yeti 700 if your primary use is cpap overnight or afternoon off-grid. Go with the Sherpa 100AC if its specific strengths below line up better with your use. Most buyers stop at the sticker price and miss this: over a full lifespan the Yeti 700 works out to about $0.26/kWh against the Sherpa 100AC's $5.28, a gap that compounds in the Yeti 700's favor the more you cycle it. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.

We ran the math on seven 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 Sherpa 100AC comes up 2,020Wh short (about 4% covered), the Yeti 700 1,525Wh (27%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Keep the essentials running through a night without power
Neither unit
The Sherpa 100AC can start the 150W peak but not hold it — 150W of surge gets it going, then the 100W continuous rating takes over, so capacity never gets a say. This is the wrong size of unit for the job rather than a close call. The Yeti 700 doesn't have the energy either — 575Wh usable against 1,645Wh, 1,070Wh short — so neither route works.

Neither unit
The Sherpa 100AC can't run the 400W peak at all — 150W is the most its inverter will pass even momentarily, so capacity never gets a say. This is the wrong size of unit for the job rather than a close call. The Yeti 700 doesn't have the energy either — 575Wh usable against 670Wh, 95Wh short — so neither route works.

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, Sherpa 100AC rates 3.3/5 (1st percentile of 25 Personal-class units), and Yeti 700 rates 3.6/5 (16th percentile of 20 Compact-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Sherpa 100AC: No App Control
Without app control, you have to physically walk to the Sherpa 100AC to check battery level, adjust settings, or monitor power draw. The Yeti 700 lets you do all that from your phone, including getting low-battery alerts.
Only the Yeti 700 Lists a UPS Mode
The Yeti 700 can sit between the wall and your gear and hand it to battery when the grid drops — rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. Worth it for a router, a desktop PC, or a CPAP. The Sherpa 100AC's spec sheet lists no UPS mode, so anything plugged into it rides an outage only as far as your reaction time.
Warranty: 5 Years vs 2
The Yeti 700 is covered for 5 years against the Sherpa 100AC's 2 years. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The Yeti 700 is rated for 4,000 cycles vs 500. In real life: at daily use, that's 11 vs 1.4 years. At weekend use (twice a week), it's 38 vs 5 years. One caution reading years across different sizes: a cycle is 677Wh on the Yeti 700 and 95Wh on the Sherpa 100AC, so count lifetime energy — roughly 2,708 kWh against 47 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.

FIXED CAPACITYFixed at 95Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 60W of solar. Limited to a single portable panel.
Limited ports. You'll likely need a power strip or splitter.

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 Yeti 700 gives you the larger ceiling); you can't add to either later.
The Bottom Line
The full picture comes down to this. The Yeti 700 edges ahead on our overall analysis, but the margin is narrow enough that your specific use case should drive the decision. Review the scenario verdicts above — if the Sherpa 100AC wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the Sherpa 100AC nor the Yeti 700 feels like the right fit, your power needs probably sit outside what these two target. If you're planning whole-home backup or running power-hungry appliances (electric heaters, window AC), you'll want a larger system in the 3,000–5,000Wh range with expansion battery support. Prices on portable power stations fluctuate frequently. Both Goal Zero discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Yeti 700 worth $450 more than the Sherpa 100AC?
The short answer: yes, if you'll actually use the extra capability. The Yeti 700 costs $450 more, but that premium buys you 582.3Wh more battery capacity (that's 3 extra hours of running a mini-fridge); 500W higher AC output (opening the door to more demanding appliances); a longer-lasting battery rated for 4,000 cycles — that's 11 years at daily use; 140W faster solar charging for quicker off-grid recovery. On a cost-per-watt-hour basis, you're paying $1.03/Wh vs $2.64/Wh. Factor in cycle life and the math flips: the Yeti 700 costs $0.26/kWh over its lifetime vs $5.28/kWh. The "expensive" unit is actually cheaper to own. For regular use, we'd pay the premium.
How does the 582.3Wh capacity difference actually affect daily use?
The Yeti 700's 677Wh battery keeps a mini-fridge running for roughly 4 hours vs the Sherpa 100AC's 1 hours. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The Yeti 700's extra capacity provides a critical cold-weather buffer. For occasional phone and laptop charging, both are overkill. This gap only matters for sustained, multi-appliance use.
Can I actually carry the Yeti 700, or is the Sherpa 100AC the only portable option?
The Sherpa 100AC at 2.1 lbs is genuinely grab-and-go. Toss it in a backpack, carry it one-handed to a picnic, take it on a boat. The Yeti 700 at 20.3 lbs is a different story. It's like carrying a large suitcase full of books. If you're setting up and breaking down camp frequently, this weight difference will exhaust you by day two.
"4,000 vs 500 cycles" — what does that actually mean for me?
In real years: the Yeti 700 (4,000 cycles) lasts 11.0 years at daily use, 38 years at weekend use (twice a week), or 167 years at twice-monthly camping trips. The Sherpa 100AC (500 cycles): 1.4 years daily, 5 years weekends, or 21 years twice-monthly. What most people miss: hitting the cycle limit doesn't kill your battery. Capacity drops to about 80%. Your 677Wh unit becomes a ~542Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
Can I use the Yeti 700 as a home UPS to protect my electronics during blackouts?
Yes. The Yeti 700 has UPS mode with true 0ms switchover (double-conversion). Even hospital-grade equipment won't notice. Plug in your desktop PC, router, NAS, or CPAP machine and it switches to battery seamlessly when the grid drops. The Sherpa 100AC does not have this feature. Without UPS, a blackout means: your PC reboots (potentially corrupting unsaved work), your NAS may corrupt its drive array, your CPAP alarms and wakes you up, and your security cameras go dark until you manually switch them over. If always-on power protection matters, this is a dealbreaker advantage for the Yeti 700.
Bottom line: should I buy the Sherpa 100AC or the Yeti 700?
We'd pay the premium for the Yeti 700. Yes, it costs more. The capability jump is real: you're stepping into a tier that handles appliances the base model can't start. The Sherpa 100AC is still solid if budget is the priority, but the Yeti 700 will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
