What fuel can I use for Jetboil?

Any fuel canister with an “EN417” nozzle will work with JetBoil stoves. This is a common standard that includes isobutane/propane fuel canisters from MSR, Primus, GasOne, and Snowpeak. You can also use butane/propane mixtures, such as Coleman. Basically, as long as the canister fits, it will work.
