The built-in cords on outdoor cooking devices are often not long enough, and although regular household extension cords will work for rotisserie kits, they will not carry enough juice to keep you pellet smoker or electric smoker going. They could become a fire hazard as they heat up trying to deliver power to the unit. To extend the cord you need a large capacity cable as measured in amps. Here's how to figure out what you need:

I'm a certified BBQ Judge and found the following; The new portable Traeger Ranger seems to be not well thought out. All the cooking directions are for the large units and over cook everything in the smaller unit. All the pellet smoke is wasted, it is drawn out the back vent and very little ever reaches what you're cooking. They have a grease bucket on the back that is supposed to catch the grease but doesn't, Grease coats the inside of the bbq and runs down the sides and out of the grill landing on whatever you have the grill on. I've been using this Traeger Ranger since June 18, 2018.

Kevin, your recommendation rocked. The Pro is one of the best pieces of grilling and smoking iron I have had my hands on in a long time! Better than the Backwoods? Well depends on how much work you want to do! Maybe not, they are first class, but ease of use? I use the Backwoods a couple times a year, the Pro has already done 8 cooks in 5 weeks. Love it.
The Smokepro comes with many of the extras that define the Camp Chef line of products, such as the easy-to-use ash removal system as well and an interior fan. This model comes with easy-to-use controls and an LED temperature readout so you can monitor internal temperature at all times, even if you're cooking at night. The unit also comes with a convenient meat probe for ensuring that perfect finish.
With 341 square inches of cooking space and a digital control board that sets the temperature from 180 to 500 degrees, you’ll be cooking whole meals in this grill, even though it’s the smallest model that Pit Boss makes. It will hold up to a dozen burgers for parties, or a chicken and vegetables for the family dinner. When cooking is done, the porcelain coated grill grates are easy to clean.
