Description : Simmer, fry, or sauté for groups with this flexible 1.5 liter system. Ideal for gourmet cooking, scouts, family camping, snow melting.
Jetboil’s new Group Cooking System (GCS) features the same burner unit as the Original Jetboil PCS Personal Cooking System but instead of a large cup for one it has a 1.5 litre pot for 2 or 3 . Like the Large cup the pot features Jetboil’s patent-pending FluxRing™ heat exchanger to double heat transfer efficiency and enable super-fast boil times.
Like the original Jetboil®, the GCS is twice as fuel efficient as traditional camp cooking systems and will bring two cups of water to boil in about two minutes, or a liter in about four minutes. Its FluxRing™ heat exchanger allows the GCS to boil up to 50 cups (12 Liters) of water from one micro-canister of Jetpower fuel.
The GCS can also be used with traditional flat bottomed cookware (like a fry pan) but without the flux ring is the same effciency as a standard gas stove.
The GCS integrates a burner with built-in igniter, 1.5 liter pot, pot support, and stabilizer into one compact unit. The 1.5 liter pot is made from hard-anodized aluminum for even heating and superior heat transfer, and features a wide aperture for easy frying and simmering, an insulating Neoprene cozy, and a snap on plastic lid for secure storage. All components, as well as fuel, stow within the pot so you can take it anywhere.
Weight 540g (without gas canister)
