An extraordinary amount of research, design, technology, and innovation goes into the creation of every Goal Zero product, from the earliest CAD drawings to the final phases of production. In our From the Engineers series, we get a behind-the-scenes look at the development of our portable power, solar, and lighting products, straight from the engineers who design them.

Rugged and reliable, the original Sherpa 100 has been a favorite among photographers, videographers, and off-grid adventurers for years; but it was time to bring this tried-and-true power bank up to speed with the latest charging technology and innovations. We redesigned the Sherpa to be sleeker, faster, and even more versatile than its predecessor. In the video below, we sat down with Goal Zero Project Manager Alex Henry and Electrical Engineering Technician Kirstie DiTomasso to get the inside scoop on what's changed, why those changes were made, and what users can expect from the new Sherpa 100AC.
