The EXPRESS II provides a safe and very affordable way to prepare hot meals away from the traditional rustic kitchen. Ideal for boaters on-the-go or in a setting with limited space, the fully contained EXPRESS II can be easily stored out of sight and out of the way. Fueled by a 7.9 oz. disposable fuel cartridge, the self igniting burner provides more than 9,925 B.T.U.s of instant heat, enough to boil one quart of water in just 6 minutes. Simply drop a KENYON fuel cartridge into the gas compartment and turn the knob. Each disposable cartridge provides up to 2-3 hours of cooking.
