Few grills spark curiosity quite like a kamado. One glance at the egg-shaped body, the thick ceramic walls, and the promise of restaurant-quality pizza in your own backyard, and it is easy to understand why these cookers have built such a loyal following.
The Sunjoy Charcoal Grill 20-Inch Kamado Grill aims to bring that premium kamado experience to home cooks who want a grill that can sear steaks, smoke brisket, and bake crispy pizzas without filling the patio with multiple appliances.
Kamado grills have a reputation for versatility, but not every model delivers the same experience. Build quality, temperature control, cooking space, and ease of use can make the difference between an unforgettable barbecue weekend and a frustrating afternoon spent wrestling with airflow vents.
This review takes a close look at the Sunjoy Charcoal Grill 20-Inch Kamado Grill, covering everything from assembly and construction to cooking performance and long-term value.
By the end, you should have a clear idea of whether this outdoor egg grill deserves a permanent spot on your deck.
Sunjoy 20-Inch Kamado Grill at a Glance
Before firing up the charcoal, here is a quick overview of what the grill brings to the table.
Key Specifications
- Grill type: Ceramic kamado charcoal grill
- Cooking surface: 20-inch grilling area
- Fuel source: Charcoal
- Included accessory: Pizza stone
- Temperature control: Dual vent system
- Built-in thermometer: Yes
- Mobility: Wheeled stand with side shelves
- Primary cooking styles: Grilling, smoking, roasting, and baking
The biggest selling point of the Sunjoy Charcoal Grill 20-Inch Kamado Grill is its ability to function as several outdoor cookers rolled into one package.
It is equally comfortable cooking burgers for a weeknight dinner or holding low temperatures during an all-day smoke session.
Unboxing and First Impressions
Opening the box reveals a substantial piece of equipment. Kamado grills are not lightweight gadgets that disappear into the corner of the patio. The ceramic body immediately communicates durability, and moving the components around quickly becomes a two-person job.
Inside the package, you will generally find:
- Ceramic grill body
- Cooking grates
- Pizza stone
- Cart and wheel assembly
- Side shelves
- Hardware and fasteners
- User manual
The packaging does a respectable job protecting the heavy ceramic shell. Given the grill’s weight, careful handling during delivery matters. Nobody wants their weekend barbecue plans derailed by cracked ceramic.
The first impression is simple: this grill feels serious. The finish is clean, the lid has reassuring heft, and the entire setup gives off the vibe of a backyard centerpiece rather than an impulse purchase.
One small joke among barbecue enthusiasts is that buying a kamado grill often starts with dreams of smoking ribs and somehow ends with debates about airflow science at family gatherings. This grill definitely invites that kind of obsession.
Assembly Process
Kamado grills are famous for excellent cooking performance, but few owners would call assembly the highlight of the experience.
How Easy Is It to Assemble?
Setting up the Sunjoy Charcoal Grill 20-Inch Kamado Grill requires patience. Expect to spend anywhere from one to three hours, depending on your comfort level with tools and outdoor equipment.
Helpful tips include:
- Assemble the cart first.
- Have a second person assist with lifting.
- Double-check the hinge alignment before tightening everything.
- Keep all hardware organized.
The ceramic body carries most of the weight, making solo assembly difficult. Attempting to wrestle it into position alone is a bit like trying to move a sleeping Saint Bernard that weighs two hundred pounds.
Instruction Quality
The instructions are reasonably straightforward, although certain steps may require some trial and error. Most users should have the grill assembled in an afternoon, but setting aside extra time is a smart move.
The reward comes once the final bolt is tightened. Suddenly, the pile of parts transforms into a sleek outdoor cooker ready to tackle steaks, pizzas, and smoked ribs.
Design and Build Quality
A kamado grill lives or dies by its construction, and this is where the Sunjoy Charcoal Grill 20-Inch Kamado Grill makes its strongest argument.
Ceramic Construction
The thick ceramic shell serves several important purposes:
- Excellent heat retention
- Improved fuel efficiency
- Stable temperatures
- Protection against temperature swings
Unlike traditional metal grills that lose heat quickly, ceramic kamados trap warmth inside. That means less charcoal consumption and more consistent cooking.
The insulation becomes especially noticeable during long smoking sessions. A pork shoulder that takes ten hours to cook demands steady heat, and ceramic grills excel in this area.
Exterior Design
Visually, the grill checks all the right boxes. The classic egg-shaped silhouette looks premium without feeling overly flashy.
Key design elements include:
- Smooth exterior finish
- Built-in thermometer
- Side shelves for prep work
- Sturdy wheeled stand
The overall footprint is substantial but manageable for most patios and outdoor kitchens.
Lid and Hardware
The lid opens smoothly and seals tightly, an essential feature for maintaining temperature control. Small gaps around the lid can wreak havoc on smoking performance, so the solid seal is a welcome detail.
The hinges feel sturdy, though regular maintenance and occasional tightening are always good habits with heavy grills.
Cooking Performance
Everything comes down to this section. A grill can look fantastic, but performance determines whether it earns a permanent place in your backyard rotation.
Heat Retention and Temperature Control
The standout feature of the Sunjoy Charcoal Grill 20-Inch Kamado Grill is its heat retention.
Once properly heated, the ceramic body holds temperature impressively well.
The dual vent system allows for fine adjustments, although newcomers may need a few sessions to master airflow management.
Important takeaway: small vent adjustments make a huge difference.
Open the vents too far, and temperatures climb rapidly. Close them too much, and the fire struggles. Learning that balance is part of the kamado experience.
Fortunately, once you understand the system, maintaining steady temperatures becomes surprisingly easy.
Grilling Meat and Vegetables
High-heat grilling is where the Sunjoy truly shines.
Steaks develop attractive grill marks and rich crusts. Burgers cook evenly, while chicken stays juicy thanks to the moisture-retaining ceramic design.
Vegetables benefit as well:
- Bell peppers char beautifully.
- Corn develops smoky sweetness.
- Zucchini cooks evenly without drying out.
One memorable cook involved a batch of ribeye steaks that disappeared so quickly the conversation shifted from sports to whether another round could fit on the grill. That is usually a good sign.
Smoking Performance
Low-and-slow cooking is often the ultimate test for any kamado grill.
The Sunjoy Charcoal Grill 20-Inch Kamado Grill handles classic barbecue favorites with confidence:
- Brisket
- Pork shoulder
- Spare ribs
- Whole chickens
- Turkey
The ceramic construction minimizes temperature fluctuations, reducing the need for constant adjustments.
For backyard pitmasters who enjoy weekend smoking projects, this consistency is one of the grill’s strongest advantages.
Pizza-Making Experience with the Included Pizza Stone
Including a pizza stone is more than a bonus feature. It dramatically expands what the grill can do.
Kamado grills are famous for reaching temperatures that many home ovens simply cannot match. Combined with the pizza stone, the Sunjoy becomes a capable outdoor pizza oven.
Pizza Results
The pizza stone produces:
- Crisp crusts
- Even cooking
- Nicely browned cheese
- Authentic wood-fired flavor
Getting the best results requires preheating the stone thoroughly. Rushing the process can leave you with uneven crusts.
A properly heated kamado delivers the kind of pizza that makes guests ask, “Wait, you made this outside?”
The answer, accompanied by a slightly smug grin, is part of the fun.
Baking and Roasting Capabilities
One of the most surprising strengths of the Sunjoy Charcoal Grill 20-Inch Kamado Grill is its versatility.
Beyond barbecue, it can handle:
- Roasted chicken
- Bread
- Baked potatoes
- Casseroles
- Desserts
The ceramic walls create an oven-like environment that distributes heat evenly.
Many first-time owners buy a kamado for steaks and burgers but end up experimenting with dishes they never expected to cook outdoors.
Ease of Use
Kamado grills come with a learning curve, but the Sunjoy remains approachable.
Lighting the Grill
Starting charcoal takes some practice.
The process typically involves:
- Add lump charcoal.
- Light the charcoal in multiple spots.
- Leave vents open initially.
- Allow the grill to preheat.
- Adjust airflow to target temperatures.
Compared to gas grills, startup takes longer. Patience pays off.
Temperature Gauge and Vent System
The built-in thermometer provides a useful reference point, although experienced grillers often supplement it with digital probes for greater accuracy.
The vent system responds well once you understand its behavior.
Key point: kamado cooking rewards patience more than speed.
This is not the grill for someone who decides to cook burgers five minutes before kickoff.
Cooking Capacity
The 20-inch cooking surface offers enough room for:
- Multiple steaks
- A whole chicken
- Several racks of ribs
- Family-sized meals
- Homemade pizzas
For average households, the capacity strikes a practical balance between versatility and manageable size.
Cleaning and Maintenance
No grill review would be complete without discussing cleanup. Thankfully, maintaining the Sunjoy Charcoal Grill 20-Inch Kamado Grill is relatively straightforward.
Cleaning the Grates
Routine care includes:
- Brushing grates after cooking.
- Removing food residue while surfaces remain warm.
- Periodic deep cleaning.
Regular maintenance keeps flavors fresh and extends the life of the grill.
Ash Removal
Charcoal grills inevitably produce ash, and occasional cleaning prevents airflow problems.
A quick cleanup after several cooking sessions helps maintain consistent performance.
Long-Term Maintenance
To maximize longevity:
- Use a grill cover.
- Protect the ceramic shell from impacts.
- Inspect hinges and hardware.
- Store accessories properly.
Ceramic grills are durable, but they are not indestructible. Dropping heavy tools onto the shell is a mistake you only make once.
Pros and Cons
Every grill involves compromises, and the Sunjoy Charcoal Grill 20-Inch Kamado Grill is no exception.
Pros
✔️ Excellent heat retention
✔️ Versatile cooking options
✔️ Includes a pizza stone
✔️ Fuel-efficient ceramic design
✔️ Strong smoking performance
✔️ Premium appearance

Cons

How It Compares to Competitors
Sunjoy vs. Big Green Egg
The Big Green Egg remains the benchmark in the kamado world, but it also commands a premium price.
The Sunjoy offers:
- Similar cooking versatility.
- Comparable ceramic heat retention.
- Included accessories like the pizza stone.
- Better value for budget-conscious buyers.
The Big Green Egg still wins in brand recognition and ecosystem support, but the price gap may not justify the difference for every household.
Sunjoy vs. Kamado Joe Classic
Kamado Joe grills include premium features and clever accessories, but they also cost significantly more.
The Sunjoy competes by focusing on the essentials:
- Solid construction.
- Dependable performance.
- Multi-purpose cooking.
For buyers who want the kamado experience without entering luxury territory, Sunjoy presents an attractive option.
Sunjoy vs. Char-Griller Akorn
The Char-Griller Akorn uses insulated steel rather than ceramic construction.
Compared with the Akorn, the Sunjoy Charcoal Grill 20-Inch Kamado Grill delivers:
- Better heat retention.
- Superior insulation.
- More traditional kamado performance.
The trade-off is increased weight and a higher upfront investment.
Who Should Buy the Sunjoy 20-Inch Kamado Grill?
This grill makes sense for several types of outdoor cooks.
Ideal Buyers
- Backyard barbecue enthusiasts.
- Home pizza fans.
- Families who entertain regularly.
- Weekend smokers.
- Grillers seeking versatility.
Buyers Who May Want Another Option
- Apartment dwellers.
- Casual users who grill infrequently.
- Shoppers seeking ultra-portable options.
- Anyone who prefers instant gas grilling convenience.
Kamado cooking rewards people who enjoy the process as much as the meal itself.
Price and Overall Value
The value proposition behind the Sunjoy Charcoal Grill 20-Inch Kamado Grill becomes clearer once you consider how many cooking styles it supports.
Instead of buying:
- A traditional grill
- A smoker
- A pizza oven
- A roasting setup
You get a single cooker capable of handling all four roles.
That versatility is the grill’s greatest strength.
The ceramic construction, included pizza stone, and efficient charcoal usage combine to create long-term value that extends well beyond the initial purchase price.
