Hot shoe adapters are small accessories that attach to the hot shoe mount of a camera. The hot shoe mount is a rectangular slot typically found on top of a camera. Here's a breakdown of the possible functions of the LITELONG LTL-K100:
Flash Adapter: an adapter that allows you to use a studio flash (flashgun) on your camera that doesn't have a standard hot shoe mount.
Microphone Adapter: the LTL-K100 is an adapter specifically designed to mount an external microphone on your camera's hot shoe.
