Fitbit Charge activity tracker

The Fitbit Charge series is a line of advanced fitness trackers designed to monitor heart rate, sleep quality, and physical activity. Originally developed by Fitbit Inc., a company founded in San Francisco in 2007, the brand became a pioneer in the wearable technology market. In 2021, Fitbit was officially acquired by Google, integrating it into the tech giant's hardware ecosystem. While specific assembly often occurs in China to leverage global electronics supply chains, the engineering and branding are spearheaded by Google's headquarters in Mountain View, California. Today, the Charge series remains a core part of Google's health-oriented wearable portfolio.
