Yes the Keurig Mini does use regular K cups that the regular Keurig uses.
The mini Keurig also is compatible with all brands of K Cups so you can use either the Keurig brand of K Cups or you can use any other K Cups for making coffee.
I love my Keurig so I can just make the amount of coffee that I need or want to drink at that time and with the old way I would make an entire pot of coffee and have to either drink it up throughout the day or use a coffee thermos to keep the coffee warm.
With the Keurig coffee machine I can make a single cup of coffee and head off to work or wherever I'm going and it's much fresher.
