A USB-C to USB-A charging cord is included for your convenience. Charging will function properly using a USB power source having a minimum charging current of just 0.5A (3.0A max). The battery is compatible with cameras using the Sony NP-FZ100 battery. In addition to its own on-board charging port, the battery also works with in-camera charging as well as external chargers. The battery is packaged in a terrific case that doubles as a protective storage unit. The case has two internal compartments for safely storing the battery as well as the included USB-C charging cable. Alternatively, you can remove the cable and store a second battery in its place. This case ensures the battery will remain clean and its contacts will not accidentally touch any metal objects or get damaged while the battery is being stored and transported.
