What's in the Chromecast box?

Google Chromecast is a small media streaming device that can be purchased from JB Hi-Fi and Dick Smith Electronics for $49. It's a simple device that can be used to stream YouTube and other content to your TV. Here's what it comes with.
As you can see, the packaging is neat.
It flips open to give you info about the connections that need to be made, and how to set it up. There is no manual.
Here's the device itself. It's noticeably bigger than a USB stick, for example, but still small enough to be discretely hidden behind a TV.
It plugs in to one of your TV's HDMI ports.
The rear has a micro-USB port for power.
There's nothing on the bottom.
Beneath the Chromecast dongle is where all the cables are packed.
Google supplies a wall adapter with an attached USB cable to power the device. However, if your TV has a powered USB port, you can just plug the other end of the USB cable into that and save yourself from having to find a wall outlet for the adapter.
An extension cable for the HDMI cable can be used if your HDMI ports are in a location where the Chromecast can't fit. We recommend using it in any case, just to give it a bit of clearance from the TV (and because if you don't use it you'll probably end up losing it).
