The classic backyard dilemma: do you fire up charcoal for that deep, smoky bite, or turn the gas knob for a quick weeknight dinner? A combo grill ends the argument by putting both fuels side-by-side in one cart, so you can sear steaks over gas while a pork shoulder smokes low and slow on the charcoal side. This guide breaks down the combo BBQ grill picks that actually earn their patio space, focusing on total cooking area, BTU output, and how honestly each one handles the dual-fuel promise.
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.
You want one machine that grills fast and smokes slow, and this roundup of the best combo bbq grill models sorts the versatile winners from the finicky ones so your money buys real cooking flexibility.
Our Picks at a Glance
How To Choose The Best Combo BBQ Grill
Buying a dual-fuel grill means deciding how you actually cook. The right pick balances your charcoal patience against specs like cooking-area split, burner count, and charcoal-pan adjustability.
Decode the cooking area
Manufacturers advertise a single big number, but that total mixes primary grates, warming racks, and sometimes an offset smoker. Look for the breakdown, like the ZH3005Y’s 1020 sq. in. total split into a 666 sq. in. main area, a 157 sq. in. warming rack, and a 197 sq. in. smoker. A bigger total only helps if the primary grates where you actually sear are generous enough for your crowd.
Weigh BTU against burner count
BTU (British Thermal Units) measures raw heat output, but more burners often matter more for even cooking. A single powerful burner can create hot spots, while three independently controlled burners let you build zones. Check both the total BTU and how that power splits across burners, especially if you plan to use one side for low-heat sides while the other sears.
Check the charcoal side’s controls
The gas side is easy — turn a knob. The charcoal side is where design matters. An adjustable charcoal pan that raises or lowers the coals gives you temperature control without dumping fuel, and a front access door lets you add coals mid-cook without lifting the grates. Slide-out ash trays and removable grease cups turn cleanup from a chore into a quick pull.

In‑Depth Reviews
1. Char-Griller Dual-Function 2-Burner Combo (E5030)
Our pick — 4.5★ from 400+ verified ratings; the strongest balance of quality and price.
The dual-fuel workhorse that sears fast, smokes slow, and still leaves room for sides.
This is the combo that earns its “Best Overall” tag by nailing the hardest part: real cooking flexibility. With 870 sq. in. of total space, you can run the two stainless burners to sear steaks on one side while the other zone roasts ribs at a gentler heat. The 24,000 BTU output on the gas side gets you up to searing temperatures without waiting around.
The charcoal side performs too, and buyers report it converts into a smoker by firing the side box with wood — no pellets needed. A owners mention notes you can smoke meats using the burner or use charcoal for other meats at the same time, which is the whole point of a combo. The EasyDump Ash Pan and push-button electronic ignition mean less time fussing and more time actually cooking.
What wins people over is the build quality — it’s a heavy, sturdy unit that owners say beats their previous grills outright. The trade-off is temperature control: the gas side hits 300°F on one burner low, 350-375°F with both low, and 500°F+ on high, but keeping charcoal under 400°F takes real attention. Assembly is the other hurdle, with some owners reporting it took 3-4 times the claimed 45 minutes and a few missing washers.
What You Get
- 870 sq. in. total space across gas, charcoal, and smoker zones
- Dual temperature gauges to watch each side separately
- Porcelain-coated cast iron grates hold heat for good sear marks
What To Expect
- Charcoal side runs hot — holding under 400°F takes practice
- Assembly is genuinely challenging and may need extra hands
- An occasional unit arrives missing small hardware
Reach for this if: you want one heavy-duty cart that genuinely does gas grilling, charcoal flavor, and smoking without upgrades.
Look elsewhere if: you want precise low-temp charcoal control straight from the start — this one rewards patience.
2. Grills House ZH3005Y 2-Burner Combo
A 1020 sq. in. beast that holds 36 burgers while the attached smoker works its magic.
If you cook for a crowd, this is the combo to beat on sheer capacity. The 1020 sq. in. total breaks down into a 666 sq. in. primary area — split evenly at 333 sq. in. for gas and 333 sq. in. for charcoal — plus a 157 sq. in. warming rack and a 197 sq. in. offset smoker. That’s room for 36 burgers at once, which is a whole block-party cookout on one cart.
The offset smoker is the star here, working as either a traditional smoker or an extra charcoal grill. A side door lets you add charcoal and pull ashes without disturbing the cooking grates. Power comes from two 12,000 BTU stainless burners plus a 10,000 BTU side burner, totalling 34,000 BTU, and the piezo ignition fires it up without needing a battery.
Owners praise the build quality, and the smoked chicken comes out excellent. One owner’s kids ages 16, 14, and 12 assembled it without help — a nice testament to the instructions. The 3-level adjustable charcoal pan (max capacity 3.3 lb in the grill, 1.5 lb in the smoker) gives you real heat control for slow-cooking, searing, or smoking. The recurring gripe is assembly: some owners hit parts that don’t line up perfectly, and directions can be unclear.
Capacity King: The biggest total cooking area in this lineup, and the only one that pairs a true offset smoker with even-split gas and charcoal zones.
The Catch: More parts mean more assembly friction — go in prepared with tools and patience.
3. Royal Gourmet ZH3002N 2-Burner Combo
The combo built around zero-fuss cleanup, with a slide-out ash tray and a big grease cup.
This one wins the “you’ll actually use it on a Tuesday” award because cleanup is genuinely quick. The charcoal side has a slide-out ash tray, and the gas side has a large-capacity grease cup plus a removable grease tray — so you dump and go instead of scraping. That slide-out ash tray and removable grease cup make this the fastest-cleanup combo in the lineup.
The 759 sq. in. total cooking area splits into 592 sq. in. of cooking grates and a 167 sq. in. warming rack, enough for 30 burgers at once. Two side shelves with three integrated hooks each keep tools and seasonings in reach. It rolls on two 6-inch wheels and two 3-inch lockable casters, so you can park it anywhere and lock it down.
Owners chose it partly for the looks — the bottom doors hide the propane tank and the branded hood plate adds polish. Performance gets real praise too: pork roasts, wings, rotisserie chickens, and fries all came out excellent. The honest caveat is durability; the frame feels less sturdy than pricier rivals, and a few units arrived with missing parts. Assembly is also a marathon, with some owners spending hours and wishing the instructions emphasized a few key steps.
Low-Mess Pick: The slide-out ash tray and removable grease cup make post-cook cleanup the fastest in this lineup.
Who This Isn’t For: Buyers who want tank-like build quality — this leans lighter and needs care during assembly.
4. GRILL DEPOTS 2-in-1 Gas & Charcoal Combo
A 41,500 BTU powerhouse with a griddle insert that turns breakfast into a backyard event.
This is the hottest gas side in the lineup, and it shows. Three independently adjustable burners at 10,000 BTU each plus a 9,000 BTU side burner give you 41,500 BTU total, so getting to searing temps is quick and even. The double-layer stainless steel lid locks in heat and resists warping even after months of use.
The versatility comes from the cast iron grill grates and a grooved griddle pan combo — you can sear burgers and steaks, then swap in the griddle for eggs, pancakes, and smash burgers at the same cookout. The perforated grill pan lets heat and smoke pass through food quickly for even results on meat, fish, and veggies. The 673.1 sq. in. total splits into 510.48 sq. in. of cast iron cooking grids and a 162.62 sq. in. warming area.
Assembly is the thing people love most — customers note the instructions are clear and simple, and that it’s a quick job with two people. The pull-out oil drip tray catches grease effectively, and the four wheels make it easy to roll across a patio. The honest limitation: if you prefer to use only gas or only charcoal, the surface area on each side is more limited than dedicated grills, and the metal isn’t the heaviest gauge.
Heat & Griddle Champ: The 41,500 BTU output is the highest here, and the included griddle pan adds a whole cooking style.
Keep In Mind: Each individual fuel side is smaller than a dedicated grill, so plan your cook for both zones.
5. Captiva Designs Gas & Charcoal Combo
The 61-inch-long counter that heats evenly across both zones and cleans up in two pulls.
This combo is built around even cooking, and that starts with the porcelain-enameled cast iron grates. They combine the heavy-duty nature of cast iron with the non-stick, rust-resistant benefit of enamel, and working with three stainless burners plus an enameled charcoal tray, they distribute heat evenly across the 690 sq. in. of cooking area. That’s 520 sq. in. of primary grates plus a 170 sq. in. stainless warming rack.
Reviewers point out temperature control is spot on, with the charcoal pan height letting you dial in the heat. The 61-inch-long cooking counter means you can run gas and charcoal simultaneously and still have room to plate. Cleanup is the standout: a tilt-designed grease tray for the gas side flows drippings directly into a hanging grease box, and both the grease tray and ash tray are full-sized and slide out.
Owners praise the build quality, with dual-fuel capability the second most-praised feature. Assembly runs about 1.5 hours and genuinely needs two people — the gas line runs long and the side racks feel awkward. The honest trade-off is that both cooking sides are a bit small, fitting roughly two steaks max, so this suits smaller gatherings rather than big block parties.
What Shines
- Porcelain-enameled cast iron grates heat evenly and resist rust
- Tilt grease tray and slide-out ash box make cleanup fast
- Clear installation instructions praised by owners
What To Know
- Each cooking side is compact — roughly two steaks max per zone
- Assembly needs two people and about 1.5 hours
- Odd knob order and awkward side racks take getting used to
Best for: smaller households and couples who want even heat and fast cleanup, not massive cook surface.
Not ideal if: you regularly feed a big crowd from both zones at once.
6. Char-Griller Flex Fuel Plus 3-in-1
Gas, charcoal, smoker, and a pre-seasoned griddle — four cooking styles on 1260 square inches.
This is the combo that tries to do everything, and it mostly succeeds. The 1260 sq. in. total cooking surface is the biggest here, and the included pre-seasoned flat-top griddle means you can pull the gas grates, drop in the griddle, and cook breakfast, fajitas, or smash burgers without a second pan. That’s a genuine 3-in-1 setup.
The gas side packs three stainless burners delivering 30,000 BTU with push-button automatic ignition, so weeknight meals are fast. The charcoal side has an adjustable tray and dual dampers to control smoke levels, letting you go from low-and-slow smoking to a hot sear on the same fuel. Owners use it every weekend and report the griddle is perfect for frying bacon.
Assembly is laborious and needs an impact driver, and there are real quality concerns — a couple of owners received units with rust already forming on the sheet metal, and one grilling tray rusted from water exposure. The pair of flue-adjustable wood boxes is a nice touch, and the thermometer reads accurately. If you want maximum cooking styles in one footprint, this delivers, but it demands care with moisture and assembly.
Four-Way Cooker: The only pick here that ships with a griddle insert and still handles smoking, searing, and charcoal.
The Trade-Off: Rust resistance and assembly quality are the weak spots — keep it covered and dry.
7. Flintex Gas & Charcoal Combo with Griddle
A 48-inch-wide profile when the side tables fold down, made for tight patios and garages.
This combo thinks about your space. Fold both side tables down and the grill shrinks a full 16 inches — from 64 to 48 inches wide — so it tucks against a wall or into a narrow patio corner for winter storage. That’s a genuinely useful detail most combos ignore. The 720 sq. in. total cooking area fits 36 four-inch burgers and feeds 8-12 guests.
The gas side features six stainless burners that heat fast and even, and the porcelain-enameled cast iron grates sear steaks with hard crusts. Lift out the two grate sections and set in the included heavy-duty cast iron griddle, and the gas side becomes a griddle station for pancakes, eggs, and smash burgers. The charcoal side has a front door so you can refill coals mid-cook without lifting the grates, plus a side crank that raises and lowers the charcoal tray.
The burners bring the grates to 850°F in 10-15 minutes, so steaks sear hard outside and stay juicy inside. Owners praise the even heat distribution and sturdy build. Assembly runs a few hours — one owner clocked about 4 hours — but the result is solid. The full-sized slide-out ash tray and removable grease collector keep cleanup quick, and the foldable tables are the standout space-saver.
Why It Stands Out
- Foldable side tables cut width from 64 to 48 inches for storage
- Six stainless burners reach 850°F in 10-15 minutes
- Front door and side crank make charcoal management easy
The Cost
- Assembly is a multi-hour job, around 4 hours for some owners
- Heavy-duty griddle and grates add weight to move around
Reach for this if: patio space is tight and you want a griddle, grill, and charcoal station that stores compact.
Think twice if: you want a quick out-of-the-box setup — budget a full afternoon for assembly.
8. Sophia & William 3-Burner Combo with Offset Smoker
The attached offset firebox forces smoke across the meat for a real smoke ring — not a token add-on.
This is the combo for buyers who take smoking seriously. The attached offset firebox functions as both a traditional smoker and an extra charcoal grill, and its offset design forces smoke and heat to flow horizontally across the meat, delivering that deep smoke ring and rich flavor. A side access door lets you add charcoal and clean ash without lifting the cooking grate.
The 840 sq. in. total splits into a 568 sq. in. main cooking surface, a 131 sq. in. warming rack, and a 141 sq. in. offset smoker, fitting 30 burgers at once. The gas side has three stainless burners delivering 30,000 BTU, heating up fast and holding consistent temperature. The porcelain-enameled cast iron grates resist rust and peeling while creating restaurant-style sear marks.
On the charcoal side, a 3-level adjustable charcoal pan lets you raise it for high-heat searing or lower it for indirect slow-cooking and smoking. Owners call the quality excellent and worth the money, with one reporting a smoked beefsteak came out “SO GOOD.” Assembly takes some effort, and a few wish the top warming rack moved back when opening the lid, but that’s not a dealbreaker. A full-size removable ash tray and a slide-out grease tray keep maintenance simple.
Smoke Enthusiast’s Pick: The true offset design plus 3-level charcoal pan gives genuine low-and-slow control.
Know Before Buying: Expect a longer assembly session, but the cooking payoff is real.
9. Oklahoma Joe’s Canyon Combo Dual Fuel
A 36,000 BTU gas side meets a firebox smoker with dampers that give you pitmaster-level command.
This is the serious pitmaster’s combo, with temperature control that goes beyond the usual knob-twisting. The adjustable firebox and smokestack dampers help maintain consistent temperatures and smoke flow, so you can smoke low-and-slow with indirect heat using charcoal and hardwood splits, then grill fast on the 36,000 BTU 3-burner propane side. Dual lid-mounted temperature gauges show accurate temps in both the smoker and grill.
The capacity is crowd-ready: a 750 sq. in. primary lets you smoke up to 2 pork shoulders and grill up to 12 burgers, plus a 281 sq. in. firebox grate that fits up to 15 wings or 6 burgers. That firebox doubles as bonus grilling space, which is a clever use of what’s usually wasted area. The porcelain-coated cast-iron grates resist rust, clean easier, and hold heat for even cooking.
Owners love grilling and smoking simultaneously, and the heavy-duty build with easy assembly gets consistent praise. Assembly runs about an hour with clear directions. The recurring gripe is durability — some shoppers say the side shelves rusting if left uncovered, so a cover is essential. The gas side works great even after weeks of use, and the storage space under the grill is a handy bonus.
What Impresses
- Dual dampers plus firebox give real pitmaster temperature command
- 281 sq. in. firebox grate doubles as extra grilling space
- Porcelain-coated cast-iron grates resist rust and hold heat
What To Watch
- Side shelves can rust if left uncovered — buy a cover
- Store under the grill is open, so utensils are exposed
Choose this for: serious smoking control and the flexibility to grill and smoke a full meal at once.
Skip if: you don’t want to manage a cover and dampers — this rewards attentive owners.
Understanding the Specs
Cooking Area & Zone Split
The headline square-inch number mixes primary grates, warming racks, and offset smokers. What matters is how that space splits between gas and charcoal, since that decides how much you can actually sear or smoke at once. A 1020 sq. in. total with only 333 sq. in. per fuel side means each zone cooks a modest batch, not a whole herd.
BTU & Burner Configuration
BTU (British Thermal Units) measures raw heat output, and higher numbers mean faster preheating and better searing. But burner count matters just as much: multiple independently controlled burners let you create heat zones, so you can sear on one side while keeping sides warm on the other. A single high-BTU burner can create uneven hot spots.
