Highly integrated portable products—such as cell phones, PDAs, MP3 players and digital still cameras—are powered by single-cell Li-ion batteries, and use a computer's USB port to transfer data files. A USB port provides bidirectional data transfer, as well as power and ground, from the host system. Using a USB port as a charging power source allows a user to simultaneously download or update files and recharge the battery for their portable product.
