This is a USB wall wart charger with a hidden talent: it also records audio and video with the use of a built-in spy-camera. It records to a removable 32GB TF Card. The camera gets its power from the house power, no battery necessary. The camera has 2 modes: either constant record or record when motion is detected. To watch recorded video, remove TF Card and put into the included USB card reader OR, alternatively, unplug the whole unit and plug into your computer using the included USB A to A cable. In either case, the TF Card should show on your computer as another drive, where you can copy videos to computer or play them directly. Very handy.
Two possible problems: firstly the camera lens is so close to the USB charging connector that is you have a charging cable plugged in part of the view is blocked by the cable. secondly, the unit's house power plug is sideways, meaning that the video is rotated 90 degrees when stored on the TF Card.
All in all, this is quite a handy device for keeping an eye on what is happening in your home when you aren't home. Understand: this is not wifi enabled, so you can't see what's happening on your phone. Still, for 25 bucks, it is quite a nice unit.
