Does Beatport Link/offline download work with just USB/CDJ or does it require you to DJ from laptop?

Getting back into DJing after years, prepping for a big gig.

Reminded how expensive music buying for shows can get with beatport. Intrigued by their new subscription model. i read the highest tier one lets you download the tracks offline. but its not clear if i then have to DJ from my laptop where i organize rekordbox, or would i be able to export said offline tracks to a USB to bring to the show?
