The Masterbuilt Gravity Series 800 is a digital charcoal grill, griddle, and smoker that merges the rich, authentic flavor of real charcoal cooking with the automated convenience typically reserved for indoor kitchen ranges. Operating with a vertical gravity-fed charcoal hopper and an electronically managed airflow system, this model eliminates the constant vent adjustments, ash management headaches, and guesswork that traditionally intimidate backyard cooks. Our comprehensive masterbuilt gravity 800 review reveals an appliance built to deliver consistent low-and-slow barbecue as smoothly as it handles high-heat griddling, establishing a dependable standard for outdoor culinary versatility.
This hybrid cooker is an outstanding match for beginners seeking genuine smoke flavor without enduring a punishing learning curve, as well as gift-givers looking to impress an outdoor enthusiast with a feature-packed centerpiece. It also serves cooks who love the concept of backyard smash burgers and breakfast hash alongside slow-smoked brisket. However, buyers with severely restricted balcony footprints, those who lack access to an outdoor electrical outlet, or campers seeking portable gear should explore lighter, non-powered alternatives.

Automated Airflow and Digital Temperature Control
The core innovation defining this masterbuilt 800 charcoal grill is its proprietary GravityFed hopper and automated DigitalFan assembly. In conventional charcoal kettles or offset smokers, managing chamber heat requires manual adjustment of intake dampers and exhaust vents, alongside constant vigilance over the fuel bed. With this design, fuel sits vertically inside a sealed tower. When lit at the base, gravity pulls fresh charcoal down as the bottom layer combusts. The integrated DigitalFan pulses automatically, feeding oxygen to the embers precisely when needed to achieve and maintain your set target temperature while minimizing heat fluctuations.
Controlling the cooking cycle is as straightforward as using an everyday kitchen appliance. Users can set heat and cook timing directly through the onboard digital control panel or adjust settings remotely via smart device connectivity using WiFi or Bluetooth. The digital display provides clear visibility of current chamber readings, supported by an internal temperature gauge and a plug-in meat probe thermometer that monitors internal food doneness. For individuals who appreciate automated ease similar to a dedicated masterbuilt 30 digital electric smoker, this charcoal unit brings that same hands-off predictability into an authentic lump charcoal and briquette environment.
Smart device pairing through the mobile application lets you track ambient pit heat and meat internal temperatures from inside your home. This capability proves invaluable during overnight brisket sessions or winter cooks, sparing you from repeatedly stepping outside into adverse weather. By standardizing airflow, the unit eliminates sudden temperature spikes and steep drops, delivering an even heat profile across the entire cook chamber.
Dual Cooking Surfaces and Griddle Versatility
Versatility is where this cooker sets itself apart from standard smokers. The package arrives equipped with traditional cast iron grill grates as well as a custom flat top griddle insert. Cast iron provides superior heat retention, radiating energy directly into steaks, poultry, and vegetables to create rich sear marks and caramelized surfaces. Swapping in the masterbuilt gravity series 800 griddle insert transforms the machine into a wide flat-top station capable of cooking smash burgers, pancakes, bacon, eggs, fajitas, and stir-fry directly over real hardwood charcoal heat.
Across its configurations, the unit supplies 800 total square inches of cooking space. This area includes the primary cooking zone along with two porcelain-coated smoking racks that sit elevated in the cook chamber. These upper warming and smoking tiers let you separate delicate foods from direct heat or hold prepared sides at serving temperature. Whether you are batch-cooking appetizers for a large neighborhood gathering or slowly infusing racks of ribs on the upper shelves, the spacious interior prevents crowded food placement and uneven cooking.
Because the griddle insert sits inside a closed, heat-regulated chamber, it cooks differently than an unhooded outdoor flat top. The lid traps charcoal-infused heat, gently browning burger buns and quickly melting cheeses without demanding specialized melting domes. The porcelain coating on the secondary racks facilitates easy food release and simple cleanup, while the cast iron cooking surface builds a robust natural non-stick patina when properly seasoned after every session.
Rapid Preheating and Broad Temperature Range
A frequent objection to charcoal cooking is the extended preparation time required to ignite the fuel bed and wait for coals to turn white. The Masterbuilt Gravity Series 800 tackles this delay directly through high-output forced-induction airflow. According to the manufacturer specifications, the grill reaches 225 degrees Fahrenheit in just 8 minutes, climbs to 450 degrees Fahrenheit in 10 minutes, and achieves a blistering 700 degrees Fahrenheit in 14 minutes. This rapid ramp-up rivals conventional gas grills while reaching searing thresholds that many residential cookers cannot match.
This wide operational range unlocks multiple culinary methods within a single footprint. At the low end, running the hopper at 225 degrees Fahrenheit transforms the unit into a masterbuilt gravity series 800 smoker that can cruise undisturbed for long stretches. The hopper holds up to 10 pounds of lump charcoal or 16 pounds of briquettes, supplying up to 10 hours of continuous heat without requiring mid-cook refueling. When high-heat pizza or restaurant-style steak searing is on the menu, dialing the unit to 700 degrees Fahrenheit yields intense radiant energy reminiscent of dedicated countertop cookers like the granitestone piezano pizza oven.
Switching between low-temperature smoking and high-temperature searing does not require rebuilding or relighting the fire bed. By simply punching a higher target into the control panel, the digital fan spools up to supply maximum oxygen, lifting chamber heat in a matter of minutes. This dynamic responsiveness lets cooks execute reverse-sear strategies effortlessly, smoking thick roasts at low temperatures before ramping the heat up to finish with a crisp, savory crust.
Build Quality, Footprint, and Setup Considerations
Evaluating the masterbuilt gravity 800 specs reveals a substantial, heavy-duty backyard cooker. Engineered with an iron outer construction and stainless steel inner components, the assembled unit weighs 204.2 pounds. The masterbuilt gravity 800 dimensions span 30.5 inches in depth, 55.1 inches in width, and 50.9 inches in height. This substantial footprint provides exceptional stability during breezy conditions and heavy lid lifts, though it requires a dedicated, level area on your deck or patio.
Because the DigitalFan, control display, and smart sensors depend on electricity, you must position the grill within reach of an outdoor power outlet or run a suitable outdoor extension cord. Unlike purely mechanical charcoal kettles, this hybrid machine cannot function without electrical power. The assembly process involves multiple panels, electrical leads, switches, and heavy cast components, making it a project best tackled with two people and a set of basic hand tools.
The black finish and charcoal accents present a rugged, professional visual profile that fits nicely alongside other outdoor appliances, such as a large-capacity master built xl electric fryer. Storing the unit under a weatherproof cover when not in use is critical to shield the electronics, hopper gaskets, and iron housing from moisture, protecting your investment for many seasons of dependable cooking.
