Jetboil personal cooking system (AKA Jetboil pcs) is really a revolutionary propane stove. Much more efficient than old time stoves. The big names like MSR or Primus followed Jetboil enterprise. MSR with their reactor and Primus and the Etapower stoves.
The Jetboil PCS was really a revolution back in 2004. This is when it got most of the awards. The big deal about it, is that it was the first to use a heat exchanger on the bottom of the pot. Given that, along with a lid and some built in windscreen, you get an amazingly efficient stove. Another cool feature they got is that the whole thing is packed in the pot itself. Naturally, you do have to get the full system, not just the burner.
Some of the tricks they used are well known like use a lid or try to fit some windscreen. The feature you can't make at home is the special pot. They welded some fins to the bottom of the pot and created a heat exchanger. It gets more heat from the flames and transfers it to the pot. This way, much more heat is used for cooking other than just blowing in the wind.
Well, they were the first with this pack-it-all-in-a-special-pot-with-heat-exchanger. Besides the efficiency, they made the whole thing real neat. The lid, for instance, is made of rubber. It sits real tight on the pot. It also got all kinds of accessories like a tripod or an option to hang the whole thing in the air. Another feature I like is its cover. The pot is coated with some isolating cloth. The result is that you can hold the pot while the stove is running. You can actually boil water without putting it on the ground. It can be useful if you don’t find any flat surface. As I mentioned, Jetboil added the ability to hang the personal cooking system. The pot is holding the burner pretty firmly. If you hang the pot or the burner, the whole thing is in the air!
Jetboil also got the Flash version of the PCS. It's the same as the standard Personal cooking system but with a color-changing heat indicator on the pot. It lets you know when the content is hot. Nice feature, but the rest remains pretty much the same. The flash is very colorful, BTW, it comes in more than one color.
Another feature they added here is a plastic cup you can assemble on the bottom of the pot after you disconnect it from the burner. I guess it helps keeping the pot from getting harmed.
Here is what I think about the Jetboil personal cooking system:
