A:AnswerThere is a K-cup filter basket you can purchase that will fit in the keurig just like a k-cup. You just add your own grounds, snap the lid shut, put it in the right way so the lid closes & brew as normal. I use one with my favorite flavored coffee.
There is NoT a warming plate as this brewer only makes single cups
A:AnswerThe difference between the K-Mini and the K-Mini Plus.
K-Mini Plus has an extra storage container for your K-Cups and also has a button to brew the coffee stronger. I own both the K-Mini and the K-Mini Plus.
