It's a Handpresso

You just add hot water and your favorite ESE pods--or, I think it takes ground espresso too. Then you pump it up like a ball pump and it builds pressure. It actually makes a decent cup. Not as good as you can do at home, but for what it is, it's pretty good.
I've had it for years. I don't fly anywhere without it and it's been all over.
I don't drink regular coffee. I have a Rocket machine at home and a Nespresso at work. I used to go to Starbucks on vacation, but I don't really like their espresso. I wanted to bring my own. Typically, I will use Kimbo or Caffe Moreno. I like that Neapolitan espresso.
