Goal Zero Sherpa 100AC vs Goal Zero Sherpa 100PD
Both carry the Goal Zero name, but they're built for different buyers. The Sherpa 100AC (95Wh, 100W) and the Sherpa 100PD (95Wh, 100W) come from different product lines with different engineering priorities. We'd buy the Sherpa 100PD.
The Sherpa 100PD's 95Wh keeps a fridge going for 1 hours. The Sherpa 100AC's 95Wh manages 1 hours. The bigger unit rides out a full weekend outage. The smaller one needs a recharge by Saturday night. But if your actual use case is camping, tailgating, or keeping devices charged, the Sherpa 100AC does the job at 2.1 lbs and $250 — no overkill, no regret.
Pick the Sherpa 100PD if you want maximum capability and room to grow. Go with the Sherpa 100AC if you need the heavier-duty specs for demanding loads. Most buyers overlook this: the Sherpa 100PD costs ~$4.22/kWh over its full lifespan, which adds up significantly over years of regular use. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.

The Bottom Line
The full picture comes down to this. The Sherpa 100PD 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 Sherpa 100PD 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%.
