Managing authentic low-and-slow barbecue traditionally demands constant vigilance, including regular vent adjustments, fuel restocking, and continuous thermal monitoring. For working professionals with demanding schedules, spending an entire Saturday tending live coals is rarely practical. The Masterbuilt 40-Inch Digital Electric Smoker addresses this time constraint directly by substituting unpredictable solid fuels with a digitally regulated electric heating element. Designed specifically for outdoor cooks who prioritize repeatable results and high-volume capacity over the constant manual labor of fire maintenance, this upright cabinet streamlines the smoking process into a structured, automated workflow.
In this focused masterbuilt mb20070122 review, the verdict is definitive: this unit is a purpose-built, high-capacity solution for cooks who want set-and-forget reliability without sacrificing authentic wood flavor. By pairing an external woodchip intake system with fully insulated alloy steel walls, it achieves remarkably stable temperatures across prolonged cooking sessions. When evaluating a vertical electric smoker vs charcoal for an efficient household, the consistency of electric heat eliminates the steep learning curve and constant oversight of traditional pit management.

02 Masterbuilt 40-Inch Digital Electric Smoker Features Explained
01 Digital Time and Temperature Controls
The central command point of this vertical smoker is its push-button digital control board, engineered to eliminate guesswork. Users can set their exact cook duration and regulate heat levels up to a maximum threshold of 275°F. This straightforward interface ensures that the electric heating element maintains a uniform thermal profile throughout the entire cycle, shielding delicate meats from the aggressive temperature swings common to manual venting systems.
Because the unit relies on steady current to drive the heating element, Masterbuilt notes that the smoker must be plugged directly into a standard wall outlet rather than an extension cord. When connected properly, the system reaches working heat in under an hour. If the cabinet takes longer than 60 to 70 minutes to reach target temperature, checking the secure engagement of the door latch and power directness quickly restores optimal thermal recovery. This level of precise regulation makes exploring the masterbuilt 40 electric smoker temperature range simple even for beginners.
02 Patented Side Wood Chip Loader
Traditional smokers force cooks to open the primary cabinet door whenever the wood supply depletes, dumping built-up heat and billowing smoke into the yard. The masterbuilt side wood chip loader solves this operational flaw by moving fuel replenishment entirely outside the cooking chamber. Cooks load their preferred wood chips into an external cylindrical chute, slide it into the smoker body, and rotate the handle to deposit the chips directly onto the internal burner tray.
This isolated mechanism maintains the internal chamber climate undisturbed, guaranteeing that delicate low-and-slow meats retain their ambient smoke bath without dropping cooking temperatures. By maintaining an unbroken thermal environment, the unit produces clean, continuous smoke infusion that enhances bark formation on lengthy cooks while keeping your hands-on intervention to a bare minimum.
03 Expansive Vertical Cooking Capacity and Racks
With an expansive 970 square inches of internal cooking area, the masterbuilt 40 digital electric smoker capacity easily outperforms standard residential horizontal grills. The upright design organizes this vast footprint across four durable, chrome-coated smoking racks that can be configured or removed depending on the size of your protein cuts. By stacking food vertically, the smoker optimizes backyard space while providing generous airflow across every level.
In real-world quantities, this interior volume accommodates up to 16 chickens, 4 whole turkeys, 8 pork butts, or 8 full racks of ribs at one time. This cavernous capacity makes the masterbuilt electric smoker for ribs and brisket a premier choice for meal prep enthusiasts or individuals responsible for catering large gatherings. The natural vertical draw allows rising heat and wood smoke to circulate evenly over each rack before venting cleanly through the top.
04 Cabinet Insulation and Monitoring Window
The smoker cabinet is built with a dual-wall design featuring an alloy steel outer shell and a stainless steel inner liner, creating a fully insulated barrier against shifting ambient outdoor weather. Securing this insulated chamber is a heavy-duty lockable door latch that creates a firm seal around the perimeter, locking both moisture and thermal energy inside for the duration of the smoking cycle.
To prevent the urge to peek inside, Masterbuilt integrated a wide glass viewing window into the front door. This transparent portal allows cooks to evaluate exterior color development, bark formation, and fluid levels without breaking the cabinet seal. Combined with the elevated clearance provided by the masterbuilt 40 vertical smoker with leg kit, the viewing window positions the cooking chamber at a comfortable, ergonomic height for effortless monitoring.
05 Integrated Moisture and Grease Management
Managing food juices and moisture is critical for achieving tender barbecue, and this model integrates a dedicated removable water bowl positioned directly above the heating element. This pan introduces gentle steam to the chamber, preventing lean cuts from drying out during extended eight-to-twelve-hour smoking cycles while simultaneously catching hot drippings from the racks above.
Cleanliness is addressed through a removable rear grease tray that collects liquid run-off channeled away from the bottom floor. After the cook completes, the grease tray slides out easily for swift disposal and washing. Coupled with an adjustable top-mounted air damper that lets the user fine-tune smoke density and moisture exhaust, the system manages interior humidity and grease accumulation with minimal fuss.

06 Before You Buy
Before purchasing the Masterbuilt 40-inch smoker, verify your outdoor electrical setup. The manufacturer explicitly mandates plugging the unit directly into a grounded wall outlet, cautioning that extension cords can cause voltage drop and prevent the unit from heating within the standard 60-to-70-minute window. Furthermore, the unit weighs 72.1 pounds and measures 50 inches in height with the leg kit attached; ensure your patio or deck has a stable, level, non-flammable surface that can accommodate its dimensions. If you need portable or apartment-balcony options where open vertical smokers are prohibited, consider checking our review of the ninja woodfire outdoor grill for a smaller tabletop alternative.
Buyers should also be aware of what is omitted from the package. The box includes only the smoker cabinet with its legs, racks, water bowl, and grease assembly; it does not include an integrated meat probe thermometer, wood chips, or a weather-resistant protective cover. If your cooking routine requires wireless smartphone app connectivity to track meat temperatures remotely, you might explore the masterbuilt 710 wifi digital electric smoker as an upgraded smart alternative, whereas this model MB20070122 relies strictly on onboard digital keypad programming.

What is the maximum food capacity of the cooking chamber?
Thanks to its 970 square inches of space across four chrome-coated racks, the smoker can accommodate up to 16 whole chickens, 4 turkeys, 8 pork butts, or 8 full racks of ribs in a single cooking session.
What materials are used in the smoker cabinet construction?
The smoker features a durable alloy steel exterior finished in black and an interior lining made of stainless steel. The cabinet walls are fully insulated and sealed with a heavy-duty lockable door latch to preserve heat and smoke.
How do you manage grease and drippings during long cooking sessions?
The smoker comes equipped with a removable water bowl placed beneath the racks to catch falling drippings while adding moisture, alongside a removable rear grease tray that collects channeled grease run-off for fast, mess-free disposal after cooking.
