What Is the Big Joe III?
The Big Joe III is the 24-inch version of Kamado Joe's Series III ceramic grill. Kamado Joe currently publishes 450 square inches of cooking space and a grill heat range of 225 to 750°F.
Current manufacturer specifications list model KJ15041021 at 51.6 inches wide, 55.1 inches tall and 406.3 pounds. Series III equipment includes the 3-tier Divide and Conquer system, SloRoller insert, Kontrol Tower top vent, Air Lift hinge, stainless charcoal basket, AMP firebox, stainless cooking grates, thermometer, folding aluminum side shelves and ash tool.
There is a point where an 18-inch kamado stops matching the way you cook. Full briskets, multiple pork shoulders, rib racks, poultry and side dishes all compete for grate space. The Big Joe III is designed for buyers who want the larger 24-inch platform and the Series III feature package in one cart-equipped grill.
The XL Big Green Egg currently publishes 452 square inches of cooking surface, while Kamado Joe publishes 450 square inches for the Big Joe III. The capacities are therefore very close on the primary published cooking-space figure. Read Kamado Joe vs Big Green Egg for the broader feature and ownership comparison.
Why the 24-Inch Cooking Surface Matters
More room for large cuts
Kamado Joe's current published figure is 450 square inches of cooking space. The 24-inch diameter gives large proteins and multiple dishes more room than an 18-inch kamado, while the 3-tier rack system adds flexibility in how food is positioned vertically.
Ceramic Mass and Fire Management
AMP firebox and charcoal basket
The ceramic body stores heat while the lower and upper vents regulate airflow to the charcoal. The multi-piece AMP firebox is designed to handle thermal expansion, and the stainless charcoal basket helps separate reusable charcoal from ash between cooks.
The practical advantage of a kamado is that the ceramic cooker and controlled airflow can support long low-temperature cooks once the fire is established. Fuel use and temperature stability still depend on setup, weather, vent position and how often the dome is opened.
The SloRoller Is a Low-and-Slow Tool
The SloRoller sits below the cooking grate and is designed to redirect smoke and heat through the chamber for smoking. Kamado Joe currently describes the SloRoller as engineered for slow cooking from 150 to 300°F.
The Four Parts You Touch on Every Cook
A 24-inch ceramic dome is substantial, so airflow controls, lift assistance and ash management matter more than they might on a smaller cooker.
Kontrol Tower top vent
Kamado Joe says the Kontrol Tower maintains its airflow setting when the dome is opened and closed. It is the upper control point used with the lower vent to manage airflow through the charcoal fire.
Air Lift hinge
Kamado Joe describes the Air Lift hinge as significantly reducing the dome weight you feel while opening the grill. That lift assistance is especially useful on the larger Big Joe body.
Built-in dome gauge
The integrated thermometer gives you a chamber-temperature reference at the dome. For food doneness, use an appropriate food thermometer in addition to the grill gauge.
Slide-out ash drawer
The ash drawer provides direct access for routine ash removal, helping keep the lower airflow path clear between cooks.

Read the Size GuideCall 833-777-2962Who the Big Joe III Is For
- Cooks who regularly need a larger primary cooking surface. The 24-inch platform is the main reason to move up from a Classic Joe.
- People who want smoking and higher-temperature charcoal cooking from the same ceramic grill. The included SloRoller supports the low-and-slow side of that range when used within its published operating guidance.
- Buyers with room for a 51.6-inch-wide cart-equipped grill and a safe delivery route.
- Buyers who want the Series III feature package included. The current product page lists the 3-tier Divide and Conquer system, SloRoller, charcoal basket, cart, folding side shelves and other Series III hardware.
If you mostly cook for a smaller group, the Classic Joe III uses an 18-inch cooking surface. For digital charcoal control and app connectivity, compare the 18-inch Konnected Joe. For an outdoor kitchen, consider the Big Joe III Standalone and confirm its model-specific installation requirements.
Common Questions About the Big Joe III
How much bigger is the Big Joe than the Classic Joe?
The Big Joe III uses a 24-inch cooking surface with 450 square inches published by Kamado Joe. The Classic Joe III uses an 18-inch surface. Compare the current dimensions and weight of the exact two models before deciding, because the larger grill also requires more patio and delivery space.
How does the Big Joe III compare to an XL Big Green Egg?
Big Green Egg currently publishes 452 square inches for the XL EGG, while Kamado Joe currently publishes 450 square inches for the Big Joe III. Primary cooking-area figures are therefore very close. Package contents, airflow hardware, cooking systems, warranty terms and accessory choices differ, so compare the current complete setups rather than cooking area alone. Our Kamado Joe vs Big Green Egg comparison covers the broader decision.
Will Classic Joe accessories fit the Big Joe?
Do not assume they will. Many covers, grates, deflectors, stones and other accessories are sized to a specific Kamado Joe body. Confirm the accessory's current compatibility list or part number before ordering.
How is Series III different from earlier Big Joe series?
Series III is the configuration that includes the 3-tier Divide and Conquer system and SloRoller along with the current Series III cart and other listed hardware. If you are comparing against an earlier model, use the exact current product pages because included equipment can vary by series and package.
Can one person move it?
Kamado Joe currently publishes the Big Joe III at 406.3 pounds. Do not plan to lift or reposition that weight alone. Arrange appropriate help and equipment for uncrating and moving the grill safely.
Does it use more charcoal than a Classic?
Fuel use varies with temperature, cook duration, weather, airflow settings and the amount of food in the grill. A larger chamber can require more fuel to heat, but there is no single fixed charcoal-use ratio that applies to every cook. Our fire-building lesson covers charcoal setup and airflow.
How does the Kamado Joe warranty work?
Kamado Joe's current warranty is component-based: key ceramic parts carry limited lifetime coverage for the original purchaser, while key metal and cast-iron parts, electronics and other components have shorter stated terms. The current warranty requires product registration, and Kamado Joe says purchases through unauthorized dealers void coverage. Review the manufacturer's current warranty terms for the exact product.
How will it be delivered?
Review the current Smokeforges product and Shipping Policy details at the time of purchase. Large grills may ship by scheduled freight, so confirm access, inspect the shipment at delivery and keep packaging until assembly and inspection are complete.
