Tremendous value for the money!
Color: Gray
As a certified espresso nerd and aficionado, I knew I had to find something to get my fix while traveling on a recent vacation. This portable espresso maker more than fit the bill!
Its compact size makes it versatile to carry in a carry-on bag for travel. The rechargeable battery will get you 2-3 shots of espresso depending on if you preheat water or start from cold. When starting from cold it easily heats to 198 when it starts extracting.
The machine is easy to use and includes bases for either ground coffee or Nespresso original capsules. I used the capsules on my trip and was more than impressed by the results. The espresso quality is great and clean up is very easy with a simple towel.
The battery does take a bit to charge with the included cable, but using a high output usb-c power source makes a world of difference.
For the money, it’s a tremendous value. Under $100 for a feature packed machine is fantastic!
Definitely a must and a must buy if you’re a coffee/espresso fan like me!

Turns on and shuts off with out pulling
Color: Gray
Mine worked once and never worked again. Continuously turns on, gets to 120 degrees and then shuts off without pulling the shot. When I requested a refund, the associate talked me into them sending a replacement instead and it was never sent. As a former barista who wanted a portable option for travel this all was very disappointing

As a true coffee lover, I’m absolutely thrilled with this portable coffee machine! It’s compact, easy to use, and makes a delicious cup every time. I can now enjoy my favorite coffee wherever I go—whether I’m traveling, at work, or just relaxing outdoors. The taste is excellent, just like from a regular machine. It’s been a game changer for my daily routine. Highly recommend to any coffee enthusiast!
