The USB 2.0 Type A Male to Mini Type B Male Cable - 4.9' (1.25m) from Panasonic is a standard USB transfer cable, with the added convenience of a winding base that pulls both ends back inside it, in order to minimize tangling and maximize portability.
It acts as a bridge between normal Type A USB devices, like a computer or printer, and Mini Type B USB devices like a digital camera or smartphone. Use this convenient and versatile cable to transfer or backup photos and videos from your camera to your PC. Or print them straight from your camera via any USB port on the printer. Because of how universal these two USB types are, there are dozens of other possible ways to transfer files and data with this cable depending on your particular devices and needs.
