Per the manufacturer: "This system lights with the click of a button and in just over 2 minutes provides two cups of boiling water for cocoa, coffee, instant soup or a gourmet freeze-dried meal."
Keurig is 1 1/2 minutes for BREWED coffee, not just hot water, ready to add coffee, wait, then press. But the Jetboil does potentially look like a smaller stored package, depending on if you bring spare fuel cans. If I was still into backpacking, I'd seriously consider one. I'm getting old, and RVing is more my speed...
