The Raspberry Pi 4 Basic Kit includes everything you'll need to get up and running with the new Raspberry Pi 4 2GB. The Pi 4 moves to a MicroHDMI Connector for monitors and a USB Type C connector for powering the board. Inside the kit you will find a MicroHDMI to HDMI cable and USB Type C Wall Adapter; two things needed to run the Pi, but that you probably didn't have sitting around already. The wall adapter provides 15.3W of power, enough to properly power the Pi and most projects.
