Charcoal: Charcoal grills are the simplest in construction and depending on size, can be very portable. The flavor produced by Charcoal grilling cannot be beat.
Electric:The Electric Grill is the least common for outdoor grilling and produces the most subtle bbq grill flavor. However, apartment or town house owners with minimal space find these portable grilling machines ideal
Gas:The gas grill construction is rather simple with burners, a system such as lava rocks to disperse the heat from the burners and cooking grates. A grill with multiple burners is more desirable as it ensures the heat will be even and no cold spots will arise.
