Both the Keurig K-Mini and the K-Compact have been used in my home hundreds of times. I have liked using both machines because of their small size and I consistently recommend these units to my readers due to the value you get out of both of these machines – they cost very little and perform well.
If you are trying to decide which unit to pickup though then there are a few things that set these coffee makers apart. Let’s quickly summarize the most important differentiating factors that you should consider before making a purchase.
The K-Mini is a water-in-water-out coffee maker that can brew any amount of coffee between 6-12 ounces in size whereas the K-Compact has a small water reservoir located in the back and can only brew 6, 8, and 10-oz cup sizes. Neither machine has a strong button however the K-Mini Plus does making it the best option for making full bodied coffee.
I usually advise people to pick up the K-Compact over the K-Classic because it’s a better value and I advise the K-Mini Plus over the K-Mini or K-Slim because it makes better coffee but the lack of a dedicated water reservoir and a charcoal water filter are significant cons to the Mini and Mini Plus.
If you look at my best Keurig list I have actually included the K-Mini Plus on my list of best value machines and the K-Compact on my list of best entry level (cheap) machines so I do like them both.

I’m going to go into greater depth in this comparison further down this page but first I want to give you the opportunity to see a couple other related comparisons that might make more sense to you.
► In Spring of 2021 Keurig released the new K-Express, it’s a basic entry level machine that may be even better than the K-Compact. You can see my head-to-head comparison here: K-Express vs K-Compact

Now with all of that out of the way let’s look at the Mini and the Compact a little more closely by starting with this video I made a while back where I reviewed everything there is to know about the K-Mini Plus.
Basically the K-Compact brews faster than the Mini or the Mini Plus resulting in weaker brewed coffee. Each unit uses the standard single point needle instead of the multi-stream technology used in the K-Supreme line of coffee makers.
The K-Mini brewers are also a bit louder than the Compact but not by much.
