Please note that you MUST sign into Google with your in order to have a fully functional browser when used portably. Unlike other browsers, some components of Chromium are locked to a given PC and will be lost if you move from PC to PC including extensions, extension settings and data, homepage and search settings, etc. This is by design of the Google Chrome team.

Passwords are not portable by default but can be made portable using a configuration option within the launcher's INI file. They may be portable while signed into Google.

Certificates and Chromium apps installed outside the browser are not portable and are installed on the local machine.

You can make Chromium Portable more portable by using a fresh profile and some settings detailed on the Chromium Portable homepage.
