This is an USB charger most commonly used by various "popular electronic brands", originally made by "a Chinese company" that changes the logo on the housing according to the request of the client company it is selling to. If you own a tablet or hybrid computer, there is a good chance you own one of these yourself.
The 3D model is quite detailed, with true to life measurements, and makes good use of the subdivision modifier. It is suited for both far and close up shots (the USB port is a separate object and can be hidden away when not visible).
The materials are organized and easy to understand. You can switch the logos for your own, move, and resize in under 5 minutes. Check the documentation for more information.
