PID: For the most precise temperature control, some pitmasters feel that a grill with a proportional-integrative-derivative (PID) controller is the way to go. A PID controller uses algorithms to keep the temperature within a couple of degrees of the setting. It doesn’t use fixed cycles to release the pellets. Instead, the controller only adds pellets when it’s necessary to maintain the desired temperature.

Meanwhile, it also has a 15-pound pellet capacity comparable to Camp Chef SmokePro (not as large but big enough to eliminate continuous wood pellet refills) and folding legs for better portability. However, certain users who’ve already bought their own REC TEC Grills Mini Portable Pellet Grill have complaints about it, like inconsistent heat distribution of the grill and poor quality control (certain grills break down easily).
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.
