The waterproof USB-C charging port cover for the Insta360 X4 Air -360 camera allows for long shooting sessions where the battery life would not be sufficient without an external power source. This cover allows you to connect the camera to an external power source while the camera's own battery is in place.
The cover is weatherproof when used with the USB-C charging cable, making it suitable for use in nature, for example for timelapse photography of the starry sky.
