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.

Protect the MasterBuilt

The 1150 cover is big enough with strings at the bottom to pull and tighten it down. I love the big logo on the front as well

Great grill that is easy to use

I bought my Masterbuilt 1050 3 years ago. The only issue that I have had is with the display. After contacting Masterbuilt, a new one was sent out to me. I love the gravity feed of charcoal and controlling temp through the app or manually on the control panel. This is a well constructed grill that I think you will enjoy.

Can handle it all

The Autoignite is the best grill investment I've made. You get so much value for the price. First of all, we all know there's nothing like cooking with wood and charcoal, right? This unit holds more than enough fuel to grill up plenty of food for my backyard parties. The digital control panel makes it so easy to get it to temperature I want to cook at. And the Masterbuilt app allows me to control what's happening at the grill even when I have to step back into the house. Highly recommend!

Extremely Versatile

I have had mine for a few years and it has held up well. Smokes and grills wonderfully. I love that you can control the temperature so easily. The attachments like the griddle top really help give you a variety of cooking styles.

Great oven, brick oven alt

User this at a party. It had great results. The bottom was perfectly done, and the top crust was delicious. I put the dough in first by itself, cooked it for 5ish minutes, then pulled it out and out the toppings and sauce on, then finished cooking it. Turned out crispy, toasty, smokey, and delicious. I am trying to convince my wife to buy one! Used in Orem Ut.

Great product!

I typically dont like pellet grills, however this one takes smoking and grilling to another level. It really is a similar process as a pellet grill, but has a better overall flavor, and doesnt get clogged up as much as a pellet grill dors. I tried this out once at a party and it made some delicious steaks!

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

$49 Flat-Rate Shipping

Anything under $49 ships at one low price. If your order increases, your shipping stays the same!

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.

No Restocking Fee

Most companies charge a restocking fee. We just don't do business that way.
