The camera is rechargeable with the USB cable provided. A full charge should last you up to 2 hours of continuous use. However, it is important to note that the battery will only drain if the camera is in use. If the camera is not in use, the battery will last significantly longer. In order to use the camera continuously without needing to charge it every time, you can keep it plugged in. This will ensure that you have a continuous power supply and do not need to worry about the battery life.
