Updated September 14, 2026 · Research-based review
Our verdict
A set-and-forget electric smoker for beginners who want digital temperature and time controls without managing charcoal or an open flame. The 710 square inch capacity across four racks handles a real cookout, but it needs an outdoor power outlet and will not produce the same deep bark as a charcoal or wood smoker.

Who this smoker is built for
This Masterbuilt model is aimed at people new to smoking meat, or anyone who wants consistent results without babysitting a fire. Because it runs on electricity rather than charcoal or wood, temperature is set and held by a digital control panel rather than manually adjusted vents and fuel, which removes most of the guesswork that trips up first-time smokers. It needs to be plugged into a grounded outdoor outlet, so anyone without easy outdoor power access, on an apartment balcony without an outlet, for example, should confirm they have a place to run it safely before buying. It suits home cooks smoking ribs, whole chickens, turkeys or pork butts for a family gathering rather than competition barbecue cooks chasing the deepest possible smoke ring.
Capacity, controls and construction
The smoker offers 710 square inches of cooking space across four chrome-coated racks, enough capacity for up to six chickens, two turkeys, four pork butts or four racks of ribs according to the manufacturer, so it can realistically feed a full table. The digital control panel manages on and off, cooking temperature and cook time with push buttons, and the unit heats up to 275 degrees Fahrenheit, a wide enough range for most low and slow smoking as well as higher-heat finishing. The body is fully insulated to help retain heat in cooler weather, and a side wood chip loader lets the user add more wood chips during a long cook without opening the main door and losing heat and smoke. Overall dimensions run about 23.6 inches wide, 42.1 inches high and 22.8 inches deep.
Setup, daily use and care
Initial setup involves attaching the included leg kit and doing a seasoning burn before the first real cook, standard practice for any electric or charcoal smoker to burn off manufacturing residue. During cooks, the side wood chip loader is the main point of interaction beyond setting the digital controls, letting the user top up chips without opening the main door and losing accumulated heat. A removable water bowl adds moisture during long smokes and also catches drippings, while a rear grease tray is designed to be pulled and emptied for cleanup. Because it depends on an electric heating element rather than a live fire, temperature swings from wind or cold weather are less of a factor than with charcoal smokers, though very cold outdoor temperatures can still slow preheating and reduce maximum internal heat somewhat.
Trade-offs and how it compares
The clearest trade-off with any electric smoker is flavor and bark: without a live charcoal or wood fire, this unit will not develop quite the same deep smoke ring or bark that dedicated charcoal or offset smokers produce, even with the wood chip loader running throughout the cook. Against other electric smokers in the same guide, the Bradley Smoker 6-Rack Digital Vertical Electric Smoker offers a similar rack-based layout with a comparable score, while Masterbuilt's own 40-inch MB20070122 and MB20072918 models step up in size for larger households at the same overall score tier. The Pit Boss PBV3D1 3 Series Digital Vertical Electric Wood Smoker is a lower-scoring alternative in the same category. This model's need for continuous chip loading during long cooks is the main day-to-day inconvenience compared to pellet smokers that auto-feed fuel.
Bottom line
This smoker earns our score of 8.4 out of 10, with strong marks for fit for the job and value, reflecting how approachable it is for beginners at this size and capacity. It ranks first in the site's electric smoker guide and is a solid pick for anyone who wants reliable, low-maintenance smoking without managing charcoal, provided they have outdoor outlet access and realistic expectations about bark compared to charcoal or wood smokers. Cooks chasing maximum smoke flavor or bark development, or anyone without a convenient outdoor power source, should look at a charcoal or pellet smoker instead, since this unit is built around convenience and consistency rather than replicating a live-fire cook.
