Today, all serious players in the pellet smoker market have switched to digital thermostatic controllers that dictate pellet-feed commands based on a temperature sensor inside the cooking box. Just like with the oven in your kitchen, you set the desired cooking temperature, and the heating system kicks on and off to maintain that set point. An LED display shows your set temp, and most models allow you to toggle between set temp and actual temp readings from the internal thermostat. Actual temperatures will fluctuate a bit as the controller switches on and off to hover around your set temp, but many sophisticated touch-pad controllers can maintain tighter tolerances than your indoor oven. Some pellet controllers also have integrated probes that let you monitor the internal temperature of whatever you're smoking. Wireless remote control and monitoring from your smartphone or tablet are also increasingly common. (You can learn more about pellet smokers on AmazingRibs.com.)
I use to have a charcoal/wood fired smoker and it was a nightmare maintaining temperature especially on a long brisket cook. Instantly I've fallen in love my YS640 coupled with a fireboard. You literally set the temp load it up and walk away with no stress or worries about maintain temperature. It provides great smoke flavor too. Yes it is an expensive purchase but that is because this thing is built like a tank and will last for decades.
Up next to find its place in our pellet grill review is the REC TEC’s mini portable pellet grill. It has a 341 square inch cooking surface with 180 degrees to 550 degrees Fahrenheit temperature limit, with 5 degrees increment. But it can easily reach 600 degrees Fahrenheit in full mode. It has a satisfactory pellet hopper capacity and has folding legs. It is great for travel and movement as it is compact and small in size.
