I’ve read all of the other search results answering this question, and these are their explanations:
- They have slightly different dimensions and/or weight
- The K55 has advanced Auto-On functionality
- The K55 is compatible with a charcoal water filter
Wrong, wrong, wrong.
Do you really want to know the difference between the Keurig K50 and K55? Here’s the truth.
They’re exactly the same.
Don’t believe me? Check out this side-by-side comparison.
Keurig K50 vs K55
Literally every single row is the same!
So, why did Keurig market the K50 and K55 as different models?
Simple: To Sell More Coffee Makers
The K50 was released first. Not long after Keurig decided to brand future versions as the K55 just to make it seem better.
Shady? Maybe a little. In reality the K40, K45, K50 and K55 are all basically the same machine. If you’re interested in these models — they’re your most basic single serve coffee makers without temperature control, strength control or display panels — just go with the one that’s the cheapest.

Make sure you don’t go straight by the price tag, though. On Amazon some listings come with a water filter or a K-cup variety pack, and thus may cost a little more.
Reviewing the K50 and K55
Both the Keurig K50 and K55 are part of Keurig’s original line of brewers, now called the Keurig 1.0 line. These brewers feature your basic “pop in a pod” technology whereby users — err… — pop in a pod.
There aren’t a lot of features, there’s little additional functionality, and the brew sizes are limited to a modest 10 oz.
The pros of these models? They’re relatively inexpensive, the brewing technology is simple and proven, and they’re about as intuitive as it gets.
However, that simplicity could be construed as a downside.
Because these models don’t have all the bells and whistles of the Keurig 2.0 brewers (models K200-K575), you don’t have much control over your final coffee.
For example, let’s say you want an 8 oz coffee. You pop in a pod, the machine pumps enough water to brew the 8 oz coffee, and you’re done.
Now you want a 10 oz coffee. You pop in a pod, the machine pumps more water…but did you add more coffee? No, you didn’t. This mean a 10 oz coffee will be slightly weaker than an 8 oz coffee, and there’s nothing you can do to fix this except get a compatible reusable pod. This way you can add ground coffee to your desired volume.
Is the Keurig K50 or K55 right for me?
As mentioned above, these models are your low-end, most basic single serve brewers. If you’re just looking for a cost-effective, convenient cup of coffee, these machines will do just fine.
