Spec deltas
Both carry the Goal Zero name, but they're built for different buyers. The Sherpa 100AC (95Wh, 100W) and the Yeti 300 (297Wh, 350W) come from different product lines with different engineering priorities. The Yeti 300 has a slight edge, but the margin is close enough that your use case should break the tie.
The Yeti 300 holds 202Wh more than the Sherpa 100AC — about 2 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 300 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 300 works out to about $0.29/kWh against the Sherpa 100AC's $5.28, a gap that compounds in the Yeti 300's favor the more you cycle it. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.
Bench Notes
What each unit does well, where it falls short, and the trade-offs that matter.
Goal Zero Sherpa 100AC
At 100W, this unit is strictly for personal electronics (phones, laptops) and small CPAP machines. Do not expect to run kitchen appliances. At only 2.1 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party.
Strengths
- +Costs $100 less
- +Lighter by 11.6 lb
Trade-offs
- –Lacks smartphone app control for remote monitoring.
- –Shorter-lived battery — rated for 500 charge cycles vs the Yeti 300's 4,000, so it wears out sooner.
Goal Zero Yeti 300
At 350W, this unit is strictly for personal electronics (phones, laptops) and small CPAP machines. Do not expect to run kitchen appliances. At only 13.7 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Longer warranty
- +Faster solar charging
- +Rated for 4,000 charge cycles — much longer battery lifespan
Trade-offs
- –Substantially more expensive (+$100) than the Sherpa 100AC.
- –Significantly heavier (+11.6 lbs), making it harder to move.

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.
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 300 lets you do all that from your phone, including getting low-battery alerts.
Only the Yeti 300 Has UPS Protection
The Yeti 300 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 300 gives you 14.3 years of warranty per $1,000 spent, vs the Sherpa 100AC's 8 years. That's 1.8× more coverage per dollar. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The Yeti 300 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. After hitting the cycle limit, the battery doesn't die. It drops to ~80% original capacity, which is still very usable.

Analyst note
The Sherpa 100AC is cheaper to buy, but the Yeti 300 is cheaper to own. At $0.29/kWh over its lifetime vs $5.28/kWh, the Yeti 300's higher cycle life and capacity make each dollar go further over the years.

Growth path
Sherpa 100AC
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.
Yeti 300
FIXED CAPACITYFixed at 297Wh, 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 300 gives you the larger ceiling); you can't add to either later.
The Bottom Line
The full picture comes down to this. The Yeti 300 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 300 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 actually carry the Yeti 300, 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 300 at 13.7 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 300 (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 297Wh unit becomes a ~238Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
Can I use the Yeti 300 as a home UPS to protect my electronics during blackouts?
Yes. The Yeti 300 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 300.
Bottom line: should I buy the Sherpa 100AC or the Yeti 300?
We'd pay the premium for the Yeti 300. 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 300 will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
