Spec deltas
Both carry the Goal Zero name, but they're built for different buyers. The Sherpa 100AC (95Wh, 100W) and the Yeti 200X (187Wh, 120W) come from different product lines with different engineering priorities. We'd buy the Yeti 200X.
On stored energy these two are effectively matched — 187Wh vs 95Wh, both good for roughly 1 hours on a fridge — so runtime isn't what decides this. The call comes down to cycle life, warranty, and the details — charging speed, app, and build — covered below.
Pick the Yeti 200X if you want the unit that wins the head-to-head on balance. 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 200X works out to about $2.35/kWh against the Sherpa 100AC's $5.28, a gap that compounds in the Yeti 200X's favor the more you cycle it. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.

Conclusion
July 10, 2026
Verdict: the Yeti 200X
The Yeti 200X takes the lead. It packs 92.3Wh more capacity and delivers 20W more power than the Sherpa 100AC. With a price tag that is $30 lower, it provides significantly better value.
Overall score margin: 693 vs 975 (−40.7%)

Statements about owner experience are cited to published reviews.
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.

Hidden gotchas and advantages we spotted that you won't find on the product page.
Only the Yeti 200X Has UPS Protection
The Yeti 200X can act as an uninterruptible power supply. Plug your PC, router, or CPAP into it and it switches to battery seamlessly during an outage. The Sherpa 100AC doesn't have this feature, so connected devices will experience a power interruption.
Warranty Value Comparison
The Yeti 200X gives you 9.1 years of warranty per $1,000 spent, vs the Sherpa 100AC's 8 years. That's 1.1× more coverage per dollar. An underrated factor if you're keeping this unit for years.

Analyst note
The Yeti 200X wins on both sticker price and long-term value. At $2.35/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner.

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.

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 200X gives you the larger ceiling); you can't add to either later.
The Bottom Line
The full picture comes down to this. The Yeti 200X 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 200X 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.
Can I use the Yeti 200X as a home UPS to protect my electronics during blackouts?
Yes. The Yeti 200X has UPS mode that keeps your devices running through power transitions. 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 200X.
Bottom line: should I buy the Sherpa 100AC or the Yeti 200X?
We'd buy the Yeti 200X. Cheaper and more capable. That combination is rare. The Sherpa 100AC doesn't offer a compelling reason to spend more unless you specifically need a feature unique to the Goal Zero ecosystem (expansion batteries, app integrations). Otherwise, clear call.
