One compatible fuel source for the GrillGun is a MAPP gas canister. Typically, these canisters power handheld plumbing blowtorches. The GrillGun is not playing around.
You can hook the GrillGun up to propane gas too. Here I've attached its hose (included) to a standard 15-pound tank. The gadget is also compatible with small 1-pound propane canisters.
