Sumatra PDF Portable is obviously the portable version of the very popular Sumatra PDF. Essentially, it allows you to run Sumatra PDF from a portable device like a USB drive or memory stick.
Sumatra PDF itself is a very capable PDF viewer which beats Adobe's own PDF reader hands down. Thanks to its low memory footprint, crashes when running this program are very rare.
Apart from just reading PDF files, Sumatra PDF Portable is capable of viewing other types of documents such as eBooks (ePub, Mobi) and book files like CBZ and CBR formats.
If you're looking for a PDF reader that's portable, then Sumatra PDF is probably your best choice.
