Key Features

Reaches 225 F in 8 minutes, 450 F in 10 minutes, or 700 F in 14 minutes
  • Includes a flat top griddle insert and cast-iron grates for low and slow smoking or high heat searing
  • DigitalFan for precise temperature control
  • GravityFed Charcoal Hopper holds 16 lbs of briquettes or 10 lbs of lump charcoal for up to 10 hours of fuel
  • Convenient fold out storage behind side shelf to prevent loss or damage to the power supply
The Masterbuilt Gravity Series is transforming the way you grill with charcoal. This innovative digital charcoal grill + smoker delivers the classic flavor and versatility of charcoal cooking, paired with the ease and precision of a pellet grill. Its GravityFed design continuously feeds fresh charcoal to the fire, while variable-speed DigitalFan technology maintains your set temperature with accuracy, controlled directly from the intuitive PID controller or your smartphone.

In just 10 minutes, it can reach smoking temperatures as low as 225 F, or climb to 700 F in only a few minutes more for a perfect steak sear. The vertical charcoal hopper holds up to 10 lbs of lump charcoal or 16 lbs of briquettes, providing up to 8 hours of consistent cooking time. As gravity pushes fresh charcoal toward the fire, spent ash drops into the bin below for easy cleanup. For shorter cooks, simply insert the included slides to cut off airflow, extinguish the fire, and save your unused charcoal for next time. Enhance flavor by adding wood chunks either to the charcoal hopper or the ash bin to generate rich, smoky notes. Heat and smoke flow evenly through a precision-engineered manifold with graduated ports, ensuring consistent results across the entire cooking chamber. The main cooking area features cast iron grates and an optional flat-top griddle insert, giving you plenty of space and versatile cooking options for entertaining any party.

Best bbq ever

The Masterbuilt 800 Charcoal Grill Griddle Smoker has become my go-to for backyard barbecues, delivering the rich, smoky flavor of charcoal without the hassle of constant tending. I recently fired it up for a 27-person cookout, and the digital temperature control was a game-changer: set it to 250°F, and it held steady through hours of smoking pork ribs and brisket, freeing me to mingle instead of babysit the fire. Toss a handful of hickory or applewood chunks into the hopper, and you get that non-stop, authentic smoke infusion that elevates everything from meats to veggies. I've flipped between the griddle and grill sides seamlessly—the griddle shines for smash burgers with crispy edges and perfectly charred vegetables, while the grill handles ribs, steaks, and hot dogs like a champ. Easy cleanup, versatile performance, and that unbeatable charcoal taste make this smoker a must-have for anyone who wants pro-level results with minimal effort.

Tons of Room

I've had my Masterbuilt 1050 for about 3 years and have been able to provide incredible smoked meats for personal and company events. Recently, we had a retirement party for one of my staff and i was able to put 2 large briskets and 2 pork shoulders on the smoker at the same time. These meats came out perfect and were enjoyed by the attendees. Having that much space in the Masterbuilt 1050 made this cook so much easier.

Great fuel with great flavor

These lumps burn smooth and even and provide that perfect smoke flavor. The fire starter blocks make getting my gravity grill going super easy.

End effect…deliciousness!

Kind of lasts

I still have my original cover on my 560 from 2019. It is very faded, ripped in one place and the draw cord has basically disintegration, but it still holds and keeps most of the unit covered and safe so I still use it

Great Concept, Major Design Fault

I bought this 3 years ago with high expectations. I have been grilling for decades and this machine seemed like the answer to those of us who prefer charcoal. I am sad to say that in my hands, he machine had a fatal flaw concern the partially used coal blocked the air flow such that the entire hopper has to be emptied to clean out the coal catcher that was blocking the fan. Because the partially burned coal blocked the removal of the coal catcher, I have stopped using the machine for two years and will have to get a Weber which I am very good at using.

When will my item arrive?

Once shipped, items usually arrive within 3-5 business days. While UPS and FedEx are our carriers for smaller items, be aware that larger items and orders are shipped via freight. The freight process is a bit more complicated than what we've all come to expect for small parcels, so it's important that you're prepared and understand what's required of you well before delivery day.

  • Most freight products ship on a pallet
  • Some carriers will call to schedule a delivery window, while others will deliver the shipment to a reasonably accessible location closest to your residence (their goal is to deliver as near a garage door as they can).
  • We'll specify which process you can expect in your shipping confirmation email.

For carriers that schedule delivery appointments:

Carriers that schedule delivery appointments require you to be home for delivery and provide your signature. The delivery is made with a semi-truck with lift gate services, and the shipment is dropped off at the curb. If you authorize the shipping company to leave the delivery without a signature, BBQGuys can't be held responsible for damages that occur during delivery. As complicated as this process may seem, we've only scratched the surface here — please review our detailed guide to freight delivery so there are no surprises when a freight shipment heads your way.

For carriers that deliver without an appointment:

Carriers that deliver without an appointment don't require you to be home or set up a delivery window, and you aren't required to sign for the pallet(s). Instead of scheduling an appointment, arranging your schedule to be home for the delivery, and signing to confirm receipt, you can sit back and let your items come to you. If you're home at the time of the drop-off, you can request the driver place your delivery in the garage; if you're out of the house, the driver will leave it near the garage or doorstep.

This item leaves our warehouse within 3-5 Business Days

30-Day Returns

Return all new, unused, and unassembled items in their original packaging, and we'll give you a full refund minus the cost of the original AND return shipping.
