If you're looking for a portable solution to making true espresso, two options are the $149 Mypressi Twist and the $85 Handpresso Domepod. Both use freshly ground coffee, though there is a version of the Handpresso that works with espresso pods, and there is a pod adapter that comes with the Mypressi Twist. One of the major differences between the two is how they are powered. The Mypressi is powered by n2o whip cream chargers, while the Handpresso is powered by your own elbow grease.
I was looking for a way to make espresso while on the road or camping with the family. I was seeking a quick and easy solution, and after doing considerable research on both of these devices, I decided to try them both in order to have a head to head comparison.
Bottomline: For my needs, which is mostly pulling double shots, the Mypressi produced more consistent, flavorful shots with good mouth feel. The shots from the Mypressi came close to what can be produced on a good home espresso machine.

This isn't to say that the Handpresso is capable of making decent shots. It just was much more difficult to pull off consistent shots that weren't on the bitter side and a bit watery. There are also several advantages that the Handpresso has over the Mypressi Twist.

I paired both devices with a Kyocera hand grinder to complete my mobile espresso solution. (More on this competent grinder in another post).
I should also mention that at home, I use an Expobar Brewtus II (now they are on to the Brewtus III) paired with a Macap MC4 doserless grinder. With this combination and a great espresso like Espresso Aficionado from Counter Culture Coffee and I am able to pull some very good coffees in the morning. In seeking a mobile solution, I wasn't looking to match what is capable from a home machine, but rather something that would come as close as possible.
First, the Handpresso Domepod. The Domepod uses a small filter basket in which you place freshly ground coffee. It has a bicycle pump-like design that allows you to pressure the device to 16 bar using your own strength. It charges quickly, and it wasn't difficult or tiring to pump, though you probably wouldn't be cranking out shot after shot for your camping crew. Once the filter basket is full, you add hot water to the dome, lock it all in place and then pull the trigger.
I found the Hanpresso capable of making pretty good shots, though I was never able to pull shots with good crema. The shots, while tasting good, were always a bit on the watery side, and that was even with using a tamper (which, in my opinion you absolutely need). Again, these shots were good, and, especially when used to make a milk-based espresso drink.
The Handpresso coffee baskets hold approximately 8 ounces of coffee, and this is where the Mypressi Twist moves in. In making a true double shot, the basket for the Mypressi Twist is capable of holding up to 18 ounces of ground coffee, making it a true double shot.
Unlike the Handpresso, the water is forced through the grounds by pulling the trigger which releases the gas in the n20 charger. No pumping necessary. The shots from the Mypressi were consistently good, with crema, good mouth feel, but a bit on the bitter side (probably due to the relatively low temps of the water).
So, the n2o charger employed by the Mypressi Twist seems to give it an advantage, though some have said the shots produce feel "gassy." The downside of course is that you have to find and use these chargers. You can't bring them on an airplane, so if you were traveling via airplane, you'd have to arrange to have the n2o chargers waiting for you at your hotel, or acquire them somewhere at your new destination. I can see several situations where this would be pretty unrealistic (i.e. multiple flights and destinations in a short period time like during a business trip).
The Handpresso's simplicity is a huge plus. You can travel with it easily. Pack it up with some good coffee and your hand grinder and you're all set. This simplicity compelled me to pick up the Handpresso first. However, after comparing the quality of the shots pulled, I ended up choosing the Mypressi Twist. I don't travel enough that the chargers are a big issue.
If you make milk-based drinks (latte, cappuccino, etc.) you'll need to figure out a way to heat and froth milk. If you're in a hotel and have access to electricity, the Nespresso Aeroccino is a great option. I'll write more on this later. There are also manual hand frothers that work quite well. There are even some options available under the accessory page on both the Mypressi and Handpresso websites.
Lastly, with either device you'll need a way to make hot (boiling) water. If you're camping, you've always got the camp stove and that works great. If you're traveling in hotels, I highly recommend picking up a small electric kettle. The water made in a hotel room coffee maker simply will not be hot enough to pull a good shot with either machine.
