The promise of an all in one grill is that you never have to choose between a quick weeknight burger and a weekend-long smoke session. You get one machine that handles the convenience of gas and the flavor of charcoal or wood. But the trouble starts when the “all in one” claim doesn’t actually cover the cooking styles you need, or when the build quality makes switching between modes feel like a chore. This guide cuts through the smoke and ranks the real multi-fuel performers by what matters most: cooking versatility, total surface area, and how easily they switch between fuels.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
If you want a single machine that does both fast propane searing and slow charcoal smoking without eating up your whole patio, the all in one grill category has never been stronger — here are the nine combos that actually deliver on that promise, ranked by real-world performance and durability.

How To Choose The Best All In One Grill
An all in one grill sounds simple — one machine, many cooking styles — but real-world performance varies wildly depending on how the fuel systems, cooking area, and build quality come together. Here are the three most important factors to weigh before you buy.
1. Cooking Surface Area vs. Actual Useable Space
Manufacturers quote total square inches that often includes warming racks and offset chambers you might not use every cook. Focus on the primary grate size first. For a family of four, you want at least 400 square inches of main cooking surface. If you regularly cook for a crowd (10+ people), look for 800 square inches or more. Remember that an offset smoker adds capacity for slow-cooked meats, but it’s not ideal for direct searing.
2. Fuel Switching — Charcoal, Gas, or Both?
A dual-fuel grill (gas + charcoal) gives you the speed of propane for weeknights and the flavor of charcoal for weekends. But not all designs make switching smooth. Some require you to remove one burner system entirely. Others let you run both fuels simultaneously across separate chambers. If you value convenience, look for a design where each fuel source has its own dedicated cooking zone without disassembly.
3. Build Quality and Assembly Difficulty
Combo grills are heavier and more mechanically complex than single-fuel models. A unit weighing over 100 pounds demands two-person assembly and a sturdy permanent spot on your patio. Check whether the grates are cast iron or porcelain-enameled — cast iron holds heat better but requires more oiling to prevent rust. Also, look for features like dampers and temperature gauges that let you actually control the heat, not just guess.

In‑Depth Reviews
1. Ninja FlexFlame Grill and Smoker | PG301BL
The smartest all in one grill that blends propane searing with electric-powered convection and woodfire smoking
This 5-in-1 system grills, smokes, roasts, griddles, and makes pizzas — and it does all of them with precision you don’t get from a standard gas knob. The digital control panel lets you set an exact temperature from 200°F to 600°F, so you aren’t guessing. A high-velocity convection fan (Super-Heated Continuous Air) circulates heat and smoke evenly around the food, which means your chicken comes out crispy on the outside and juicy inside, as buyers consistently report. The propane side fires up to 600°F in about 7 minutes, while the woodfire smoker uses just 2 cups of pellets for authentic bark and a smoke ring.
It is heavier than it looks at 130 pounds, and unlike a pure gas grill, you need a 3-prong outdoor extension cord to power the fan and electronics. Buyers report that the 424 sq. in. main cooking space fits up to 3 whole chickens or 14 steaks. Some owners mention that the wood pellets only last 30-45 minutes, and you need to buy the pizza stone and griddle plates separately. But the 10-year limited warranty on the build gives you long-term confidence that most combo grills don’t offer.
Why it earns the top spot
- Digital temperature control (set 200°F to 600°F precisely) removes the guesswork
- Convection fan delivers even cooking and crispy results that pure gas grills can’t match
- Woodfire smoker creates real BBQ bark and smoke ring without a separate offset chamber
The real-world tradeoffs
- Requires an electrical outlet — not suitable for off-grid tailgating
- Pellet consumption runs about 30-45 minutes per load, so long smokes need refills
- Accessories like the pizza stone and griddle plates are sold separately, raising the total cost
Reach for this if: you want a single machine that can switch between gas grilling, electric smoking, and griddling without learning a separate system — the digital precision makes it especially good for beginners who want pro results.
Think twice if: you don’t want to run an extension cord to your grill, or you prefer the hands-on simplicity of a pure charcoal fire.
2. Oklahoma Joe’s Canyon Combo DLX
The heavy-hitting dual-fuel combo that gives you a serious offset smoker and a 3-burner gas grill in one frame
With a total cooking space of 1,434 square inches, this is the biggest grill on this list by a wide margin. The charcoal side is a true offset smoker with an adjustable firebox and smokestack dampers, letting you run low-and-slow at consistent temperatures. The gas side cranks out 36,000 BTUs across three burners for quick searing. The integrated fuel gauge on the propane tank shows you exactly how much gas is left — no more running out mid-cook. One executive chef owner reports loving the versatility of switching between briquettes, smoke, or gas depending on the meal.
At 191 pounds, this is not a grill you move around the yard casually — it needs a dedicated spot. Assembly takes about 90 minutes according to buyers, and you need two people for the heavy barrel section. Some customers have reported missing parts, but the manufacturer support is responsive and ships replacements free. The painted steel interior is less premium than porcelain-coated options, but the heavy-gauge build and wagon-style wheels make it a long-term investment for serious outdoor cooks.
What makes it special
- True offset smoker + 3-burner gas grill in one unit — no compromise on either side
- Fuel gauge on the propane tank prevents mid-cook gas runouts
- Massive 1,434 sq. in. total area can feed a large party with room to spare
Where it falls short
- Weighs 191 pounds — not portable, needs a permanent patio position and two-person assembly
- Painted steel interior is more prone to rust than porcelain-enameled options without regular care
- Some units arrive with missing hardware, though manufacturer support reportedly handles it fast
Grab this if: you cook for crowds regularly and want both a dedicated offset smoker for low-and-slow and a gas grill for quick midweek meals.
Look elsewhere if: your patio space is tight or you want a grill you can move around your yard easily.
3. Char-Griller E5030 Dual-Function
The ingenious dual-fuel design that runs propane on one side and charcoal on the other, each with its own thermometer
This combo grill separates the two fuel sources into dedicated chambers: the left side runs on 24,000 BTUs of propane with two stainless steel burners, and the right side is a full charcoal grill with an EasyDump Ash Pan. Combined, the two sides give you 870 square inches of cooking space — that is roughly 2.6 times the area of compact combos like the SKOK 3-in-1. The dual temperature gauges let you monitor each side independently, so you can sear steaks on gas at 500°F while smoking ribs on charcoal at a lower temperature. Owners mention that the gas temp regulation is tricky — one burner low runs around 300°F, both low about 350-375°F, and high up to 500°F — but the versatility is class-leading in this price bracket.
The unit weighs around 125 pounds, so assembly is a two-person job. The porcelain-coated cast iron cooking grates hold heat well and clean up easier than bare cast iron. A reviewer who bought it by accident ended up loving it: they use the gas side for veggies and the charcoal side for meat, calling it “low tech amazing value” that made their Traeger and Kamado-owning friends jealous. One wrinkle: the charcoal side reportedly struggles to stay below 400°F, so it is better for direct grilling than low-and-slow smoking from the start.
The dual-fuel advantage
- Dedicated gas and charcoal chambers let you cook two ways simultaneously without swapping parts
- 870 sq. in. total area gives you room for a large cookout
- Porcelain-coated cast iron grates combine heat retention with easier cleanup
What to watch for
- Gas temperature regulation requires some practice — the low setting may still run hot
- Charcoal side tends to run above 400°F, making true low-and-slow smoking difficult without modifications
- Heavy assembly (~125 lbs) needs a second person
Best for: the cook who wants true dual-fuel flexibility without spending premium money — you get both gas and charcoal in one well-designed package.
Not for: anyone wanting a dedicated low-temperature offset smoker; the charcoal side runs hot by default.
4. Sophia & William Offset Smoker
The one-piece offset smoker that seals heat properly so you can actually control your low-and-slow temperature
Unlike many offset smokers that use a two-piece chamber design — which leaks heat and smoke — Sophia & William builds the main cooking chamber as a single welded unit. That means you get a true seal, which is the difference between fighting temperature swings all day and holding steady at 225°F for hours. The total cooking area is 941 square inches, split between 551 sq. in. of primary grates, a 198 sq. in. warming rack, and a 192 sq. in. offset firebox grate. One reviewer with 48 years of grilling experience says this is the last charcoal grill they will ever need, praising the heavy steel build and the fact that after seasoning, a single load of charcoal was only 33% burnt after three hours.
At 123 pounds, you will want help getting it off the delivery truck. The thermometer is color-coded with “SMOKING” (100-250°F), “Bar-B-Q” (250-350°F), and “GRILLING” zones — a thoughtful touch that makes temperature targeting intuitive even for beginners. Some owners mention it can leak a bit of grease at the end of the barrel, missing the drip bucket, so you may want to position it over a paver or tray. But for pure charcoal smoking performance at this price, the build quality and seal are tough to top.
what separates it
- One-piece smoker chamber eliminates the heat and smoke leaks common in two-piece designs
- Color-coded temperature gauge makes it easy to find and hold smoking temps
- Heavy-gauge steel and large 10-inch wheels provide exceptional stability
Watch out for
- Grease can leak from the barrel end, missing the drip bucket — sit it on a protective surface
- Weighs 123 pounds, so you need a second person for assembly and positioning
- No gas option — this is a pure charcoal machine, so it takes longer to fire up than a dual-fuel model
Buy it for: the best charcoal smoking experience in this price range — the sealed chamber gives you temperature control that cheaper offsets simply cannot match.
skip it if: you want the speed of gas for quick weeknight cooks; this is a dedicated low-and-slow machine.
5. MELLCOM 3-in-1 Pizza Griddle Grill
The 74,000 BTU propane monster that swaps between a griddle, a pizza oven, and four burners of grill space
This gas grill stands out because it comes with a pizza oven and pizza stone as included accessories — not sold separately. The left side of the grill accepts a griddle plate or the pizza oven, turning your standard cookout into a pizza night or a breakfast-on-the-griddle session. It uses 5 burners total (four main + one side burner) and pushes out 74,000 BTUs, which is more raw power than any other grill on this list. The porcelain-enameled cast iron grates are rust-resistant and non-stick, making cleanup less of a chore.
Assembly, however, is a major undertaking. Several buyers describe it as very time-consuming, with multiple pieces that need adjustments to fit properly. There are also reports of shipping damage (dents, scratches) and quality control issues like a hinge rod that required drilling. Some users say the direct flame exposure can burn food even at low settings due to insufficient shielding. If you get a well-built unit, the cooking performance across griddle, pizza, and standard grilling is solid. But the manufacturing consistency seems to be a gamble at this price point.
Why it stands out
- Pizza oven and griddle are included in the box, not aftermarket add-ons
- 74,000 BTUs across 5 burners offers more raw heat output than any other pick here
- Porcelain-enameled cast iron grates resist rust and clean up easily
What gives us pause
- Assembly is notoriously difficult and time-consuming according to many buyers
- Quality control issues include shipping dents, scratched parts, and misaligned holes
- Flame shielding may be insufficient — some report burning food even on low heat
Perfect for: the backyard chef who wants to make pizzas regularly and doesn’t mind spending a weekend assembling the grill.
Think twice if: you want a low-maintenance out-of-box experience with consistent quality; the manufacturing variance here is real.
6. Royal Gourmet GD4002T Tailgater
The portable grill-and-griddle combo that packs 40,000 BTUs into a tailgate-friendly 11-inch tall frame
This 4-burner propane grill is designed for tailgating and camping trips where you need both a traditional grill grate and a flat-top griddle. The ceramic-coated griddle plate sits alongside the cast iron cooking grates, so you can cook bacon and eggs on one side while searing steaks on the other. Each burner pushes 10,000 BTUs for a total of 40,000 BTUs across the 430 sq. in. cooking surface. The spark electronic ignition lights the grill with one push of a button, and the slightly grooved drip tray channels oil into the grease cup for mess-free cleanup.
At just 11.02 inches tall when folded, this is among the most portable options here. It runs on standard propane tanks, and the 2-in-1 design means you barely need to reassemble when switching between modes — the griddle and grates are both integrated from the start. The tradeoff is that you lose both the charcoal flavor and the smoker capability, so this is really a gas-only combo for quick, versatile outdoor cooking on the go. If you want wood-fired flavor at a tailgate, this won’t deliver it.
Portability perks
- Compact folded height (11 inches) makes it easy to transport and store
- 4 independently controlled burners give you flexible heat zones across the 430 sq. in. surface
- Ceramic-coated griddle and cast iron grates let you switch from pancakes to steaks without swapping parts
Where it limits you
- No charcoal option — this is pure propane, so you miss out on smoky flavor
- Not a true smoker; no offset box or dedicated smoking chamber
- Cooking area (430 sq. in.) is on the small side for feeding a crowd
Best for: the tailgater or camper who wants a fast, portable grill-and-griddle combo that sets up in minutes.
Not for: anyone wanting charcoal flavor or low-and-slow smoking — this is a gas-only, on-the-go machine.
7. SKOK 3-in-1 Combo
The compact 3-in-1 combo that runs on charcoal and propane, with a cast iron griddle for true camping versatility
This SKOK grill packs three cooking modes into a tabletop-friendly footprint (32.7 x 18.9 x 17.5 inches). It runs on either charcoal or propane, and includes a cast iron griddle plate and an enameled cooking grate so you can choose your surface. The griddle area measures 184.51 sq. in. for teppanyaki-style cooking, while the grilling area adds 146.48 sq. in. for traditional barbecue. The dual-lid design helps retain heat better than single-lid portable grills. Customers note that a major perk is the ability to hook up a full-size 20-pound propane tank instead of the disposable 16-oz cans, cutting down on waste and cost.
A customer reported using it on a camping trip and cooking a wide variety of foods without any issues. The included extras — paper towel holder, bottle opener, thermometer, storage shelf, and hooks — make this feel like a complete kit rather than a stripped-down portable. The main limitation is the 331 sq. in. total cooking area, which is small compared to the 870 sq. in. of the Char-Griller E5030. For a family of four, you can manage, but for a large party you will be cooking in batches. It is a true 3-in-1 for its size, just not for big crowds.
Why it works for camping
- Accepts a full-size 20-lb propane tank in addition to small camping canisters
- Includes cast iron griddle, enameled grate, and charcoal box for maximum cooking flexibility
- Comes with useful extras: paper towel holder, bottle opener, thermometer, and hooks
The size tradeoff
- 331 sq. in. total area is small relative to full-size dual-fuel combos like the Char-Griller (870 sq. in.)
- Primarily a tabletop unit — not as sturdy as a freestanding cart grill on uneven ground
- Charcoal mode may be less convenient to switch to mid-cook compared to gas
Grab this for: camping trips, tailgates, or small patios where you want charcoal, gas, and griddle options in a portable package.
pass on it if: you regularly cook for more than 4-6 people at once — the cooking surface is too limited.
8. Royal Gourmet CC1830W Offset Smoker
The entry-level offset smoker that gives you 811 square inches and an authentic side firebox for real smoke flavor
For the price of a mid-range gas grill, you get a full charcoal offset smoker with an 811 sq. in. total cooking area — 443 sq. in. on the main porcelain-enameled steel wire grates, plus a 184 sq. in. warming rack and 184 sq. in. offset smoker chamber. The side firebox lets you burn hardwood chunks or charcoal to generate real smoke, not just gas-fired flavor. The 2-level height-adjustable charcoal pan holds up to 4.4 lbs of coal and gives you some heat control. One buyer who used it 10-12 times for steaks, burgers, and chicken called it a good, inexpensive grill for the money.
The powder-coated finish over alloy steel looks decent but is not as thick as premium options, so expect some rust after a couple of seasons if you don’t keep a cover on it. The wood-painted side tables offer good prep space, and the mesh bottom shelf holds up to 20 lbs of accessories. Assembly is straightforward, and buyers consistently mention “sturdy” and “easy to put together” in their reviews. The biggest tradeoff is that this is charcoal-only — no gas option — and the offset smoker design means you need to tend the fire to maintain temperature. It is a great starter smoker for someone wanting to learn authentic low-and-slow without spending +.
What you get for the money
- Genuine offset smoker design with a side firebox for authentic charcoal smoke
- 811 sq. in. total cooking space at this price is excellent value for budget buyers
- Adjustable 2-level charcoal pan gives you some control over heat zones
Where corners are cut
- Charcoal-only — no gas burner, so every cook requires a full fire start and tending
- Powder-coated finish is thinner than premium grills — rust may appear without diligent cover use
- Single wall construction means more heat loss in cold weather compared to insulated smokers
Best for: the budget-conscious buyer who wants to learn offset smoking without a big investment — it covers the basics well for the price.
Not ideal for: anyone who needs the speed of propane or wants a low-maintenance experience; this needs hands-on fire management.
9. Ninja Woodfire OG321
The plug-in electric grill that smokes, bakes, roasts, air fries, and broils without a single propane tank
If you live in an apartment, condo, or on a balcony where open flames and propane tanks are not allowed, this Ninja is your all in one solution. It runs on 1760 watts of electricity and creates real wood-fired smoke using just half a cup of wood pellets — no gas, no charcoal, no open flame. The 6-in-1 functionality covers grilling, smoking, baking, roasting, air frying, and broiling. It fits 6 steaks or 30 hot dogs on the 141 sq. in. nonstick grate, and you can air fry up to 3 lbs of wings or BBQ smoke a 9-lb brisket. The weather-resistant build means you can leave it outdoors, though Ninja recommends storing it under a cover.
At just 28.8 pounds, this is the lightest grill on the list by a factor of four compared to the 125+ pound dual-fuel units. That also means the cooking area (141 sq. in.) is proportionally small — you won’t be cooking for a crowd. Buyers rave about the even heating and easy cleanup, with one calling it the best grill they have ever owned. A reviewer noted that the initial burger cook produced too much smoke until they learned to let it dissipate first. The wood pellets add an authentic flavor that electric grills usually lack, but the small surface area means you will cook in batches for more than two people.
Why it wins for compact spaces
- Fully electric — no propane, no charcoal, no open flame, making it balcony-safe
- Real woodfire flavor from wood pellets in 6 different cooking modes
- Weighs only 28.8 lbs, so you can move it from storage to patio with one hand
The size limitation
- Cooking surface is just 141 sq. in.— very small compared to the 870 sq. in. charcoal/gas combos
- Requires a nearby electrical outlet; not usable off-grid
- Only suitable for 1-3 people per batch; not practical for large gatherings
Perfect for: apartment dwellers, balcony cooks, and anyone who wants real smoke flavor in a small electric package with no fuel storage hassle.
Not for: large families, weekend entertainers, or anyone who wants searing power above what 1760 watts can produce.
Understanding the Specs
BTU vs. Cooking Area
BTU (British Thermal Unit) measures raw heat output, but it is misleading on its own. A 24,000 BTU burner on a 24-inch grill will sear nicely, while 24,000 BTUs spread across 48 inches will feel weak. Always divide the total BTUs by the cooking area in square inches to gauge how hot that specific surface actually gets. The MELLCOM’s 74,000 BTUs on a compact frame, for example, will heat up faster than the Oklahoma Joe’s 36,000 BTUs across its enormous 1,434 sq. in. footprint.
Offset Smoker vs. Direct Charcoal
An offset smoker has a separate firebox attached to the side of the main chamber. Heat and smoke from the firebox flow horizontally through the main chamber and out the smokestack, cooking food indirectly at lower temperatures (typically 225-275°F). This is the classic setup for low-and-slow barbecue. A direct charcoal grill, by contrast, has the coals directly under the grate, producing higher heat (350-600°F) for searing burgers and steaks. All in one grills like the Char-Griller E5030 let you use both methods in the same unit by dedicating one side to each.
