When looking at a pellet grill also consider the material its made from. A majority of pellet grills on the market are made from painted steel. However, the quality of that steel and the paint can vary. A good high-temp powder coat paint can stand up to high heat without blistering or flaking. This is essential, because once the steel is exposed, it will rust. Even if the grill body is painted well, you have to look inside. The fire pot and diffuser plate have the potential to corrode and are two of the most common parts that need replacing. With some painted steel grills, such as Traegers®, you can can upgrade the grill and hopper lids to stainless steel, as well as the firepot, diffuser, and drip pan.

This grill is mounted on a bracket with a sawhorse design with wheels that provide it mobility in all terrains. It has a steel construction with a powder-coated finish, giving it a great look and a sturdy body. It has a hopper capacity of 18 pounds but it’s enough to continuously cook and smoke food in its 380 sq. inches of cooking area. Its porcelain-coated grill grates give you a no-rust and non-stick cooking experience that you won’t forget.


Perfect for traveling and tailgating, or even just a smaller patio space, the Traeger Junior Elite 20 is small in size, but delivers big wood-fired barbecue taste. Impress your friends by grilling, smoking, roasting, baking, braising, or BBQing at any tailgate or outdoor activity. The integrated Digital Elite Controller keeps temps within +/- 20 degrees F and makes setting the grill temperature as easy as turning a dial.
Central to all pellet cookers is a digital controller similar to the controllers on modern indoor ovens. You select a temp you want, and there is an LED display that tells you the actual temp. Some of the controllers also are programmable so you can cook at a certain temp for a determined time. Some have leave-in meat probes that can dial back the ovento a holding temp when the meat hits its mark.
From the models and brands that I have reviewed here, I highly recommend the REC TEC 680 Wood Pellet Grill as the best pellet smoker. This comes with a grill technology, which gives you more convenience, whether you are a novice or an experienced grill master. If you have found this article to be helpful, please share it with your friends and family and help them make the right decision.
A few other mentionable features are that it has a highly durable temperature proof textures powder coat finish, it features auto start. The REC TEC Wood Pellet Grill accommodates temperatures from 180 degrees Fahrenheit to 500 degrees Fahrenheit with 5 degrees increment. This amazing temperature control features let you be in control of how much heat you want to cook your food in, without having to worry about it getting dry or burnt. This low increment allows you to cook delicate meats like fishes and seafood as well! It smart grill tech makes sure that the temperature you set is always consistent and constant. It also has an “Extreme” smoke feature from the 180 to 250 degrees Fahrenheit setting that intensifies the smoke in the grill.
There are no food probes with this controller as there are on the MAK Pellet Boss, and the controller is mounted to the surface with two screws and no gasket so I fear rain could get into the electronics, but after more than a year of sitting out without the cover in rain and snow, the controller on the IPT I tested is still working fine. Ortech recommends covering your smoker.
Due to having such features and being the best Lousiana Grills Product, the Louisiana Grills LG Pellet Grill 1100 could not escape our vigilant gaze when we did our research. However, it had some shortcomings, mainly due to its build and price that did not allow it to make it into our pellet smoker review. Regardless, we could compare it with some of our products that it had tied with. But as always, we could only choose the top 10 products for this review and this had to go. Regardless, this still is a great product, worth mentioning.

With over 375 reviews, this product had an impressive review rate. On its first 22 days, it got its first 10 positive reviews. Ten days after, it got its 2nd set of 10 positive reviews, and its 3rd set of 10 positive reviews after seventeen days. Online reviews have shown that, just like us, customers have been satisfied with the overall performance of this smoker from Traeger.
Sometimes an inexpensive, less efficient pellet blend might be just fine for burgers or chicken breasts. Other times, you may want to step it up with a premium flavored pellet where whole turkeys, prime rib roasts, or a nice brisket can really shine. No matter what you read in any grouping of pellet grill reviews, know this: pellets are not all made equally. You will wind up with one or two “go to” brands over time that you simply prefer – sometimes for their efficiency (leaving little ash), others for their flavor.
Wood pellet grills are a great addition to any home because they combine everything you love about a smoker with a standard grill. Depending on the model that you buy, you can make smoked dishes like brisket and sausage at the same time that you make burgers, hot dogs and other dishes on the grill. These grills are great for family dinners in the summer and for parties and special occasion celebrations.
Hey Jimmy, thanks for commenting here about your experience. I’m sorry to hear your experience was less than optimal. I have only cooked on the Traeger pro models. I do know that it is good practice to vacuum out the burn pot after cooks of a few hours or more. Not sure this was where your problems were initiated. Did you contact Traeger support? If so, what was their response?

Alex Coleman’s family has been farming in the Piedmont region of North Carolina longer than anybody remembers. The area is famous for “Lexington Style” barbeque, which focuses on pork shoulder barbeque served up with a variety of sauces based on ketchup, vinegar, and peppers. But Alex’s daddy taught him so much more than that about grilling and smoking...Read more
PID Controller–PID Controllers (Proportional Integral Derivative) are devices that most of the grill manufactures don’t fully utilize yet. They can be found as a separate device attached to the grills if you’re handy enough, but all the manufacturers aren’t fully considering them yet. Using a PID controller, you can accurately maintain the temperature while cooking and ensure that the food is cooked automatically to perfection without much supervision.

-Warranty-(Forgive my soapbox here, folks.) I'd give it 5 stars if Camp Chef would give it a real warranty. One year is pathetic and WAY below the industry standard. Camp Chef, I know you are reading this because you guys are too excited about your great new product to not pay attention to feedback like this. Nut up and stand behind your awesome product. Why would anybody buy a product from an industry newcomer with no track record when you yourself are only willing to stand behind it for 1 lousy year?... Especially when the "industry leader" will guarantee their product for 3 years?!?! You are communicating that you have 1/3rd the amount of trust in your product that Traeger does. That's terrible! You should exceed what they are offering just to make the point in the industry! At a minimum, you should at least match their warranty just so it doesn't become a stumbling block to potential customers. Look, you basically took the lil tex and said "ok boys, so how can we make this better?!?" You did that! You totally knocked it out the park! Why cheap out with the warranty?!? As a customer, it makes me nervous that you know something I don't.


The digital controller controls temperatures from 150F to 500F in 5-degree increments; that’s the most precise we’ve found on a pellet grill, and gives you a good, precise burn. There’s also Sense-Mate, a thermal sensor that monitors the smoker’s internal temperature, so you can keep an eye on it remotely on your phone via Wifi, letting you adjust the temperature from the app.
Thanks Kevin for the reviews and content. Like many of the folks I too will be purchasing a pellet pooper. I have narrowed my choices to a MAK 2 star and a Memphis Elite. One of the earlier posters indicated on the Memphis that the effective direct grilling space was about 1 square foot. I am assuming that with the smaller footprint of the MAK that the direct “flame zone” is less than that. I’m just wondering how much less.
You want even grilling: One of the downsides of using a charcoal grill is ensuring that the entire grilling area is evenly heated. Spreading the charcoal evenly and avoiding hot spots is difficult. Traeger’s pellet grilling system overcomes this problem with a fan that evenly distributes the heat throughout the grilling area, much like a wood-fired oven would have.

Hey Tom, first, thank you so much for reading the article and expressing your approval of it. It means a lot to me that the information posted on this site is useful for the people. To your question about pellet grills, yes. You must always use BBQ grilling pellets with these cookers. You cannot use raw wood with them. However, should you find yourself with access too hard woods like Hickory or maple, or fruit woods like apple, cherry, or peach – this is something that could be readily used in a charcoal smoker.
Pit Boss Wood Pellet Grills are filled by all regular BBQ wood pellets. The computerized control board lights the grill and permits you to set the cooking temperature from 180° to 500°F. Fan constrained convection cooking takes out the requirement for a rotisserie and makes an adaptable situation for grilling, simmering, smoking, braising and preparing. The Pit Boss 340 has 340 sq. in. total cooking surface with porcelain covered cooking grids. With complete structural quality and strength, the Pit Boss 340 is made to last.
This unit will not let even a single pellet go to waste. No need of worrying whether you’re out of pellets or not. You can carry pellets at a maximum of 20 pounds, with the digital thermostat ensuring the pellets are being used properly. This saves you loads of cash and gives you smoking food simultaneously without wasting time in refilling pellets.
With the Camp Chef PG24S, you won’t have to constantly refill your hopper. Your pellets will be used as efficiently as possible, as this product comes with a hopper that can hold up to 18 pounds of wood pellets. With the digital heat control system, it instantly feeds the pellets into the grill to maintain the ideal cooking temperature. This ensures that food is cooked most satisfyingly.
Central to all pellet cookers is a digital controller similar to the controllers on modern indoor ovens. You select a temp you want, and there is an LED display that tells you the actual temp. Some of the controllers also are programmable so you can cook at a certain temp for a determined time. Some have leave-in meat probes that can dial back the ovento a holding temp when the meat hits its mark.
GrillGrates(TM) amplify heat, prevent flareups, make flipping foods easier, keep small foods from committing suicide, kill hotspots, are easier to clean, flip over to make a fine griddle, and can be easily removed and moved from one grill to another. You can even throw wood chips, pellets, or sawdust between the rails and deliver a quick burst of smoke to whatever is above. Every gas grill needs them.
So far this smoker is fabulous! There is a learning curve, and this is not a "set it and forget it" smoker. You have to make sure you don't run out of pellets as the smoker will shut down. Tried a pork butt, but I wasn't watching it close enough, so I had to finish it in the oven. Still delicious. Next made some boneless skinless chicken breasts which turned out wonderfully.
Each grill is porcelain coated, like you’d find on professional grills, for exceptional heat transfer and easy wipe cleaning. This attention to excellence is extended over the whole machine, with everything made out of heavy gauge steel and top quality material. The only real let down is the wheels, which are kind of low quality, but they’re real simple to switch out.
Camp Chef's Woodwind Pellet Smoker is a quality smoker and super searing grill wrapped up in one. As I mentioned above, though pellet smokers are often referred to as pellet grills, most have a limited grilling capability at best. To fill this gap, in 2017, Camp Chef introduced its optional LP gas Sear Box, which can be added to any of its current SmokePro pellet smokers. Woodwind is a package deal that comes standard with the Sear Box and sells for about $50 less than a SmokePro with the optional Sear Box. As a bonus, Camp Chef is one of the few brands on the market with an ash-removal system that deposits ash in a cup under the smoke box for easy disposal.

Right off the bat I could tell this smoker was made in America! While putting it together the holes actually matched up! ATBBQ- beat the 5-6 week lead time and delivered in two weeks out to California. This thing is a beast- the heavy weight I was looking for in a smoker and it has the most consistent temp I have ever had with a pellet grill. I messed up on the first pellet grill that starts with a "T" and should have started out with the Yoder YS640. If you are on the fence or wondering if it's truly worth the cash. All I can say is yes...YES it is. Pull the trigger and order this now- you won't be disappointed. I don't work for Yoder or ATBBQ- I'm just a experienced BBQ'r that could not be happier! Thanks Yoder and ATBBQ,

Hello John. Thank you for your comment and questions here! In short, you will not get the same smoke profile on a pellet smoker that you do with your BGE or PBC. That said, I do think there are some ways to mitigate this. Yes, I do feel the Smoke Tube and Mojo Cubes add smoke flavor that is detectable. Fred at Mojo Bricks does good work, and I recommend his products without reservation. This said, I have been happy with the smoke level I see in the pellet smokers I’ve used. Starting low does and ramping up later is a technique I’ve used with success when extra smoke is desired. The Rec-Tec grill gets high reviews across the board. I have no hesitation backing them, along with Green Mountain Grills. Both are made in China, but the companies have great customer service support and strong user communities. I believe each has a well-contributed Facebook group or two.
I bought a Yoder YS480 three years ago. I still use my cheaper pellet grill for everyday smokes, but I use the Yoder when I want to get serious. It does a beautiful job on baby back ribs (can do up to 8 racks laying flat on the grate) and I have smoked two complete turkeys at a time. The only time I have had a problem after 2 1/2 years of smoking was caused by a failed temperature probe. I got a new probe, installed it in a few minutes, and was back up and smoking again.

Just like your kitchen oven, a pellet grill must keep a consistent temperature in order to produce great food. To get tender brisket, the temperature needs to stay as close as possible to 250°F for the entire 12-plus hours its cooking. A pellet grill’s ability to do that is largely determined by its control board, which is essentially the brains of the pellet grill. There are different types of controllers, and their precision and consistency varies. Most can hold a consistent temperature in ideal conditions, but not all controllers can maintain a tight temperature in the cold, wind, and rain.
From the models and brands that I have reviewed here, I highly recommend the REC TEC 680 Wood Pellet Grill as the best pellet smoker. This comes with a grill technology, which gives you more convenience, whether you are a novice or an experienced grill master. If you have found this article to be helpful, please share it with your friends and family and help them make the right decision.
How much food are you going to smoke? This is important because some of the top pellet smokers are relatively large. And if you’re not looking at smoking a lot of meat, you might purchase a unit that’s too big. Conversely, if you buy a unit that’s too small, you are going to be frustrated because you’re going to make some delicious meat just not as much as you need.
The MAK Pellet Boss will increase or decrease with the press of a button in 5°F increments and has a probe in the oven that keeps the temp pretty solid. As with any thermostatically controlled oven, even your indoor oven, the thermostat cycles heat on or off as needed. So it you set it for 225°F it cycles on til it hits 225°F, then off until it drops to 220°F, then on to 225°F. There are three meat probes and the Boss can be programmed to change the cooker temp when the meat hits a target. I've had one for several years outdoors in the Chicago winters and summers without a cover and no problems.
Buying factory direct means that you are purchasing a product directly from the manufacturer, which eliminates the need for a middleman. There’s no need for the product to go through any kind of supply chain and acquire additional costs in order to reach you. The price tag that’s displayed on factory direct products doesn’t contain any markup to compensate for additional costs. Buying factory direct gives you the best chance at receiving the lowest price possible for the product you’re purchasing.
This pellet grill has a 440 square inch cooking surface and weighs 73 pounds. It measures 36 by 18 by 39 inches in dimensions and is made out of durable steel and heavy duty 16 gauge steel construction. It has a dial-in control with an LED read-out. Its temperature reaches from 180 degrees to 500 degrees Fahrenheit. It also comes with a meat probe. This Pit Boss is a worthy name to be in our pellet grill review’ list.
Now comes the best part about pellet smokers: they can conveniently do all these three. Coming with a large cooking space and a lid, the top rated pellet smokers would allow you to keep them open or closed, depending on what results you are looking for. With a dedicated space for putting your charcoal, you can use it as a charcoal grill, smoker or a barbecue. Or you can use it like a kitchen oven using the direct fire from the firepot. Finally, it does what it was made for – pellet smoking. Using small hardwood pellets running over the firepot in a corner, this smoker uses a fan to distribute the heat and smoke throughout the grilling area. This indirect heat ensures that the food is slow-cooked and smoked over long periods of time.
As the launcher of the pellet smoker trend, it’s only natural that the innovative Traeger Pellet Grill Company would perfect its pellet grill technology and come up with some of the most affordably priced smokers around costing $300 upwards. It’s the Ford Motors of the pellet grilling world and many a pellet griller on the market to date owes the existence of their industry to this one company.
As another one of the most important elements to consider when it comes to a quality grill, we wanted to make sure that the grill was easy to use, turn on, and cook with. With this, we discovered that all brands have the same design system when it comes to using the grill. The best quality grills, which we have shared, come with an electronic auto-start ignition so individuals do not have to deal with starting a fire or having to light a propane grill. Everything is done with a flip of a switch or a press of a button. With that said, this happens to be one of the best design elements of the grill that makes it easy to cook. The next is the controller system, which quickly became a criterion on its own.

Because the wood pellets are the grill’s fuel, you should pay careful attention to the pellet hopper, the chamber that holds the pellets. You want a large enough hopper to hold all the pellets you need for a single cooking session. Look for a hopper with at least an 18-pound capacity if you want to slow cook for longer periods without having to refill the hopper.
Pellet grills come in many different sizes that accommodate food as per those sizes. However, even the smaller kinds are able to cook up a meal for a large family of 4 to 5 at a time! The larger ones are obviously able to accommodate large portions of meat and other food in it. In fact, some large pellet grills are used to cook up a whole baby lamb or large fishes at a time! This is one appliance that has been proven ideal for feeding a lot of heads at a time without the stress and the hard work of course, making it great for small to medium parties and get-together.
Heating pellets, meanwhile, can consist of a variety of woods, including softwoods like pine, which contains resin that infuses food with a bitter unappetizing taste. Because it doesn’t really matter what’s in heating pellets, so long as they burn, they can also include bark and leaves and other impurities that can adversely affect food flavor and possibly pose a health risk if ingested. Because less care goes into the production of heating pellets and they're not guaranteed to be 100% pure hardwood, heating pellets are significantly less expensive than BBQ pellets, making them appealing to budget conscious shoppers. However, resist the temptation to save a few bucks and never use heating pellets in a pellet smoker.
The Pit Boss Grills 340 Wood Pellet Grill is a great grill with dial-in digital control and led read-out. Pellets are 100% natural hardwood. This grill has got an automatic start and cool down. It’s heavy duty with 16 gauge steel construction. It’s easy to assemble. It’s a little expensive. However, other grills are more expensive and seeing that I would recommend this to anyone.

Craft amazing wood-fired creations with the Trager renegade Elite pellet grill. From grilled steak, to smoked ribs, & even a freshly baked Apple Pie, the set it & forget it ease of use allows any home chef to cook it all. Swap the gas & charcoal barbecue for 100% pure hardwood pellet flavor & grill, smoke, roast, bake, braise, or BBQ your next masterpiece.

From the second I ordered the YS640 to the day it arrived the service and dialogue with ATBBQ was first rate. They actually care about the customers service experience! One word of caution for anyone thinking about buying this beast. Make sure you have someone strong to help you unload it off the pallet! My neighbor was amazed at the heft and build quality!


I bought this directly from Traeger. Beware that this model is now discontinued. They replaced it with the Traeger Renegade Pro without notice. The new model has an updated saw horse design and a new digital controller with probes. It does not come with the handy spice rack however. To each their own but I'd check with Traeger prior to purchase. That said, I paid more from them so if this is discounted, grab it. I love mine!

Hey Drew – thank you for your comment. All told, most pellet grills are going to average about 1.2 to 1.5 lbs per hour. of pellets per hour at 225, and closer to 1.75 lbs. as you get up to 275. It’s tough to gauge, which is why you are probably seeing different figures across the web. Ambient temperature and pellet composition play a role as well as grill temp. Sorry I don’t have better information for you.
You want to easily switch to different smoky flavors: Changing flavors in your Traeger grill is as easy as changing the pellets that you place in the hopper. Through its website, Traeger offers several different smoky flavors of hardwood pellet offerings, including hickory, mesquite, apple, maple, cherry, and oak. And Traeger’s website provides information on which types of hardwoods provide the best smoky flavor for certain types of foods, which can help you successfully use this grill immediately out of the box.

Renegade Pro is built to suit all your cooking needs; it can cook, braise, broil, char, sear, bake, smoke, roast, grill, and barbecue your food to that “melt-in-the-mouth” perfection. To bring about this versatility, it offers different temperature settings, such as “Hot and Fast” and “Low and Slow” that can be controlled using its Digital Pro Controller.

However, with a pellet smoker, you can ensure that new pellets are being fed into the fire automatically, ensuring that it burns for longer and while it burns, it imparts with its flavors. It doesn’t need to be soaked and fed into a burning pile of coal to work. Above that, sawdust, when separated by the heat and being burned, gets a larger surface area to burn with and thus sends out a bigger burst of flavor per pellet.

The Rainier is also hearty as hell. It survived banging around in the bed of my truck for four years. And I didn’t exactly baby it, cramming it into the limited storage space in my truck with paddles, helmets, and all manner of gear. But I never worried that it wouldn’t fire up to cook another meal. Once, one of the stubby rubber legs popped off as I was pulling the Rainier out of my truck. The stove sat crooked for a weekend, but I eventually found the leg and simply screwed it back on.
With the internal temperature sensor, meat temperature probe, and a digital temperature readout, the PG24 pellet smoker takes the guesswork out of your cooking process. An advanced digital temperature chip gives a more steady smoke and temperature, eliminating large temperature swings and giving a more consistent cooking temperature. The patented Ash Can Cleanout System makes clean up the easiest out there.
3-Position Controller - 3 position controllers, also called LMH controllers, have just 3 temperature settings—low, medium, and high—which correlate to roughly 225°F, 325°F, and 425°F. They feed pellets in fixed cycles that are determined by which setting you choose. With just three settings to choose from, though, you have less control over cooking temperatures than more advanced controllers. These controllers are often found on lower priced pellet grills.
You’re concerned with ongoing costs for fuel and power: The wood pellets used with Traeger grills are more expensive than propane or charcoal. You can expect to spend $1 to $3 per grilling session using wood pellets. Propane is far less expensive to operate in a grill, while charcoal fits somewhere in the middle of the cost range. And beware of cheap pellets from third-party manufacturers that contain softwoods like pine. They burn much faster than hardwoods, so the end cost won’t be that much different because you’ll use more of them. And they can introduce unwanted chemicals and contaminants to your food. You will also have some electrical power costs with these Traeger pellet grills.
We have reviewed the best pellet smokers on the market today after doing our extensive comparative research. However, there were some hidden gems that could not make it to our top 10 product list because of one reason or another e.g. due to their high prices, unavailabilities in some regions, and other factors. Also, some just failed to get in our top 10 list only because it was a top 10 list and not a top 20 list. Regardless of the reasons, here are a few honorable mentions that failed to make it to this top 10 best pellet smoker review, but are still worthy in their own rights:
Camp Chef is the company that perfected the pellet grill formula that Traeger made up, hence its introduction of an effective pellet auger that dispenses pellets only when needed and a large capacity hopper that reduces the need for pellet refills (that people find really annoying). It’s economical in terms of fuel rationing even though the griller itself is quite expensive.
After about 10-15 hours of cooking, you should remove the burn cup and dump the ash. If the ash builds up it can prevent ignition. Ash also accumulates in the bottom of the unit, but doesn't impact cooking. A vacuum cleaner with a hose makes short work of it. Only a few manufacturers, such as Blaz'n Grill Works and Camp Chef have a slide out combustion cup that makes cleanup much easier, but you still have to get underneath the deflector occasionally and suck out fly ash that has scattered around the lower part of the grill body.
I am a pellet grill newby and a recent convert from the backyard charcoal grill to the Yoder YS640. After a ton of research on pellet grills, I jumped in the deep end with this grill and have won raving Family fans after four grilling adventures. I have never cook ribs...tried three racks using a special rub and several ours on the Yoder...and my wife who isn't fond of ribs was eating the left overs the next day! This grill is easy to use and creates fantastic tasting food. My only regret is that I didn't purchase the grill a lot sooner.
If you live in an area where wood furnaces are used (not like down here in FL where a few heat strips will do the trick), you may also be familiar with pellet furnaces. In short, pellets compressed from sawdust and wood shavings fill a hopper and are then fed into a burn pot using an electric auger system. The auger, which is basically a long screw, delivers pellets to the burn pot based on the speed dictated by the unit’s thermostat.
