Access to electricity has its downfalls. First, if the cord isn’t long enough you will need to make sure you have a proper extension cord. Using the wrong cord is a fire hazard. Do the math (watts / volts = amps) and make sure you have the right extension cord. The smoker is also less mobile, and if it's stored outside it absolutely must have a cover. Electrical components and weather don’t mix.
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
