You want the smoky kiss of charcoal on a brisket, but you also need the instant convenience of gas for a Tuesday-night burger. Buying a barbecue grill combo means you no longer have to choose between flavor and speed — but you do have to choose between dozens of models with wildly different BTU ratings, cooking areas, and smoker capabilities. One wrong pick and you could be stuck with a flimsy frame that rusts before Labor Day or a cramped cooking surface that won’t hold a rack of ribs.

I’m Min — the co-founder and writer behind Gadgets Feed. I’ve spent hundreds of hours analyzing the technical specs, customer feedback, and real-world performance data across the dual-fuel grill market to separate the genuine workhorses from the backyard disappointments.

Whether you are outfitting a patio for weekend gatherings or upgrading a camping setup, this guide to the best barbecue grill combo on Amazon will help you invest in a rig that delivers consistent heat, easy cleanup, and lasting construction.

How To Choose The Best Barbecue Grill Combo

Buying a dual-fuel grill means you are balancing two cooking systems in one chassis. Most buyers focus on the total cooking area, but the real differentiators are the quality of the charcoal pan adjustment, the total BTU from the gas burners, and the material of the grates. A high BTU number on paper means nothing if the burners are cheap stainless steel that rusts or the heat distribution is uneven across the cooking surface.

Charcoal Pan Adjustability

A fixed charcoal grate limits you to a single heat zone. Models with a height-adjustable charcoal pan let you raise the coals for searing or lower them for low-and-slow smoking. This single feature determines whether your combo grill can function as a proper smoker or just an oversized charcoal burner.

Grate Material and Construction

Porcelain-enameled cast iron grates retain heat better than bare steel or chrome-plated wire, and they resist rust far longer. Painted steel grates are cheaper but will flake and corrode after a few seasons. For a combo grill you plan to keep for years, insist on porcelain-enameled cast iron on at least the primary cooking area.

Burner Configuration and Side Burner

A gas grill with three main burners gives you better zone control than a two-burner model. A dedicated side burner adds versatility for simmering sauces or boiling corn while the main grills are occupied. Look for at least 24,000 total BTU from the gas side to get reliable searing temperatures.

Best Overall

1. Captiva Designs Propane Gas and Charcoal Grill Combo

690 sq. in.3 Main Burners

The Captiva Designs combo hits the sweet spot between price, performance, and build quality. Its 520 square inches of porcelain-enameled cast iron primary cooking grates retain heat for even searing while resisting rust far better than painted steel alternatives. The three stainless steel burners deliver enough BTU to reach searing temperatures quickly, and the independent gas and charcoal controls let you run both sides simultaneously without cross-contamination of fuel types.

Assembly takes about 90 minutes with two people, and the slide-out grease tray and ash box make post-cook cleanup significantly easier than models where grease collects in hard-to-reach corners. The side burner adds a useful 8,530 BTU for sides or sauces, and the locking casters keep the 105-pound frame stable on uneven patio stones.

Customer feedback consistently highlights the even heat distribution on the gas side and the charcoal pan’s height adjustability, which allows for real temperature control when smoking. The primary drawback is that the storage cabinet under the grill isn’t fully enclosed, so wind can blow ash around if you don’t remove the tray immediately after each use.

Why it’s great

  • Porcelain-enameled cast iron grates for heat retention and rust resistance
  • Three main burners plus side burner for versatile cooking zones
  • Easy-clean slide-out grease tray and ash box

Good to know

  • Storage cabinet is not fully enclosed
  • Gas line hose is longer than necessary for some setups

2. GREEN PARTY 3-Burner Propane Gas and Charcoal Grill Combo

37,000 BTUAdjustable Charcoal Pan

With three main burners producing 37,000 BTU total, the GREEN PARTY combo offers the highest gas-side output in this mid-range group. That extra thermal power translates to faster preheating and better recovery when you open the lid to flip a rack of ribs. The charcoal side features a crank-adjustable pan that lets you dial in the distance between coals and food without burning your knuckles.

The lid-mounted dampers and invisible front air vent work together to maintain airflow without opening the lid, which minimizes heat loss during long smokes. The 685 square inch cooking area is split between porcelain-enameled cast iron grates on the primary section and warming racks above, giving you enough space for about 24 burgers simultaneously.

The grease management system funnels drippings into a removable cup, and the ash collection tray slides out for quick disposal. A handful of user reports mention uneven heat distribution on the gas side when using only one burner, and the metal grill plates can warp if subjected to a direct flame without food for extended periods. The included customer service has a strong reputation for sending replacement parts without hassle.

Why it’s great

  • Highest gas BTUs in its class for fast preheating
  • Crank-adjustable charcoal pan for precise heat control
  • Air flow dampers designed for minimal heat loss during smoking

Good to know

  • Some users report uneven gas heat on single-burner use
  • Metal grill plates can warp under high direct heat without food

3. Sophia & William Charcoal and Propane Gas Grill Combo

690 sq. in.Porcelain Cast Iron Grates

The Sophia & William combo differentiates itself with a focus on heat retention and even distribution. The porcelain-enameled cast iron grates on the 520-square-inch primary cooking area pair with porcelain-enameled flame tamers to minimize hot spots — a common complaint on cheaper dual-fuel models. The gas side’s three stainless steel burners deliver 28,650 BTU, and the 8,530 BTU side burner handles side dishes without stealing main cooking real estate.

The charcoal side uses an adjustable tray with a crank handle, allowing you to move between searing and smoking temperatures without lifting the grate. Both the grease tray and the ash tray are full-size slide-out units, making post-cook cleanup faster than models with tiny collection cups that overflow during long smokes. The 105-pound weight and locking casters keep the grill planted on uneven ground.

Some buyers have reported that the burners and splash guards show surface rust if left uncovered in wet climates, and the sheet metal on the side shelves feels thinner than the main body. The cooking height from grate to closed lid is 10 inches, which is adequate for whole chickens but tight for taller cuts like beer-can chicken. Despite these caveats, the heat consistency and build quality at this price point are impressive for a mid-range dual fuel grill.

Why it’s great

  • Porcelain-enameled cast iron grates and flame tamers for even heat
  • Full-size slide-out grease and ash trays for easy cleanup
  • Crank-adjustable charcoal pan for versatile cooking styles

Good to know

  • Side shelves feel less robust than the main frame
  • Burners may show surface rust in humid environments without a cover
Best Value Combo

4. Char-Griller Dual-Function 2-Burner Gas and Charcoal Grill E5030

870 sq. in.Electronic Ignition

The Char-Griller E5030 is a well-established model that prioritizes straightforward operation over flashy extras. Its 870 square inches of total cooking space — including a 157-square-inch warming rack — give you room for large batches, and the electronic push-button ignition eliminates the need for matches or batteries. The two stainless steel main burners produce 24,000 BTU combined, which is adequate for medium-heat grilling but may struggle to reach screaming sear temperatures on cold, windy days.

The EasyDump ash pan is a genuinely useful feature that lets you empty charcoal ashes mid-cook without pulling the entire grate assembly apart. The dual temperature gauges mounted in the lid allow you to monitor both the gas and charcoal sides independently. The charcoal side includes an adjustable pan for basic heat control, though it lacks the fine-tuning crank found on more expensive models.

Customer feedback notes that the assembly instructions are confusing — a common theme across this category — but online assembly videos solve most of the challenges. The heavy-gauge steel body and matte powder coat finish feel substantially sturdier than budget options from lesser-known brands. The primary limitation is that the charcoal side tends to run hot even with the vents closed, making true low-and-slow smoking difficult without constant attention to air dampers.

Why it’s great

  • Heavy-gauge steel body with matte powder coat finish for durability
  • Electronic push-button ignition for instant lighting
  • EasyDump ash pan for mid-cook ash removal

Good to know

  • Charcoal side runs hot, making low-temp smoking challenging
  • Assembly instructions are unclear; online video recommended
Budget Champion

5. Grills House ZH3005 2-Burner Gas and Charcoal Combo Grill

34,000 BTU823 sq. in.

The Grills House ZH3005 is a classic entry-level dual fuel that delivers impressive value for its price point. It splits 823 total square inches into a 333-square-inch gas section and a 333-square-inch charcoal section plus a 157-square-inch warming rack. The two stainless steel main burners each output 12,000 BTU, and the side burner adds another 10,000 BTU for a combined 34,000 BTU — competitive output for a two-burner system.

The charcoal side includes a height-adjustable pan, a smoke stack, and a side air vent that give you genuine temperature control capability despite the budget price tag. Dual lid-mounted thermometers let you monitor each side independently. The piezo ignition system sparks without batteries, which is one less thing to replace over the grill’s lifetime.

Assembly takes about two hours with the help of an online video, as the included paper instructions are challenging to follow. Several buyers noted minor cosmetic dents from shipping, and the cooking area, while generous on paper, feels tight when cooking for more than six people simultaneously. The 78-pound weight makes it easy to move around a patio, but the lighter gauge steel means it won’t hold up to harsh winters as well as heavier models.

Why it’s great

  • Impressive 34,000 BTU output for a budget-priced two-burner grill
  • Height-adjustable charcoal pan with smoke stack for temp control
  • Piezo ignition requires no batteries

Good to know

  • Lighter gauge steel is less durable in harsh weather
  • Assembly instructions are difficult to follow without a video
Best for Smoking

6. Grills House ZH3005Y Gas and Charcoal Combo with Offset Smoker

1020 sq. in.Offset Smoker

The ZH3005Y builds on the standard ZH3005 by adding a 197-square-inch offset smoker box, bringing the total cooking area to 1,020 square inches. This attachment functions as either a traditional smoker for low-and-slow briskets or as an extra charcoal grill for high-heat cooking. A side door on the smoker box allows you to add charcoal chunks or wood chips and remove ashes without disturbing the main cooking chamber.

The 3-level adjustable charcoal pan on the main charcoal side gives you three distinct heat zones — high for searing, medium for direct grilling, and low for smoking. The offset smoker itself has a 1.5-pound charcoal capacity, which is modest but sufficient for a few hours of smoking before needing a refill. The gas side retains the same 24,000 BTU from two stainless steel burners plus the 10,000 BTU side burner.

Like its sibling, the assembly process is arduous without video guidance, and cosmetic shipping damage is a recurring theme in customer reviews. The overall 87-pound weight is manageable, but the extended 67.72-inch width means you’ll need ample patio space. The offset smoker adds real smoke flavor capability that the standard two-burner model lacks, making this the choice for budget-conscious buyers who prioritize smoking over pure grilling.

Why it’s great

  • Includes offset smoker box for authentic low-and-slow cooking
  • 3-level adjustable charcoal pan for multiple heat zones
  • Side door on smoker for easy fuel and ash access

Good to know

  • Overall width of 67.72 inches requires significant patio space
  • Smoker charcoal capacity is limited to 1.5 pounds

7. Char-Griller Flex Fuel Plus 3-in-1 Gas and Charcoal Grill

1260 sq. in.Includes Griddle

The Char-Griller Flex Fuel Plus redefines what a barbecue grill combo can be by including a pre-seasoned flat-top griddle that replaces the gas side grates. This turns the grill into a three-in-one station: gas grilling, charcoal grilling, and griddle cooking for breakfast, fajitas, and smash burgers. The 1,260 total square inches of cooking space is the largest in this lineup, and the three stainless steel burners on the gas side deliver 30,000 BTU.

The charcoal side uses an adjustable tray and dual dampers for temperature and smoke control. The firebox is large enough to hold standard charcoal briquettes or lump charcoal, and the dampers give you meaningful control over oxygen flow for smoking. The automatic ignition fires the gas side with a button push, and the grate hook and tool holder keep your workspace organized.

Early customer feedback praises the griddle’s performance for breakfast cooking but notes that the included flat-top rusted quickly when exposed to rain or moisture without immediate drying. The assembly process is labor-intensive — a reviewer recommended using an impact driver — and the thin sheet metal on the grill body has disappointed some buyers who expected thicker-gauge steel at this price point. The griddle insert is a genuine differentiator, but the build quality shows some cost-cutting compromises.

Why it’s great

  • 3-in-1 capability: gas grill, charcoal grill, and flat-top griddle
  • Massive 1,260 square inches of total cooking space
  • Automatic ignition and adjustable dampers for smoke control

Good to know

  • Griddle surface rusted quickly in some units without immediate drying
  • Thin sheet metal body may not match premium build expectations
Serious Smoker’s Choice

8. Oklahoma Joe’s Canyon Combo Dual Fuel Smoker and Grill

1031 sq. in.Offset Firebox

Oklahoma Joe’s brings pitmaster-level design to the dual-fuel market with the Canyon Combo. It pairs a dedicated offset smoker firebox (281 square inches of grate space) on the charcoal side with a 36,000 BTU three-burner propane grill on the gas side. The total 1,031 square inches of cooking area includes 750 square inches of primary space — enough to smoke two pork shoulders and grill 12 burgers simultaneously.

The offset smoker features adjustable firebox and smokestack dampers that give you real control over temperature and smoke flow, which is essential for low-and-slow cooking. The firebox door provides easy access to add charcoal or wood chunks without opening the main smoking chamber. The gas side uses porcelain-coated cast iron grates that resist rust and retain heat for even cooking. Dual lid-mounted temperature gauges let you monitor both chambers independently.

The heavy-gauge steel construction with a high-temp finish is built to last, though the grill ships with only two locking casters — some buyers recommend upgrading to four for easier mobility on uneven ground. The fire management requires more attention than a pellet smoker; users report needing to tend the fire about every 25 minutes to maintain stable temperatures. When running both gas and charcoal sides simultaneously, heat spillover can push the gas side above 300°F even with only one burner lit.

Why it’s great

  • Dedicated offset firebox for serious low-and-slow smoking
  • Adjustable dampers on firebox and smokestack for smoke control
  • Porcelain-coated cast iron grates for heat retention and rust resistance

Good to know

  • Requires frequent fire tending (~25 min intervals) for temperature stability
  • Only two locking casters included; four recommended for mobility

9. Weber Genesis E-325 Liquid Propane Gas Grill

PureBlu BurnersSear Zone

The Weber Genesis E-325 is a premium gas-only grill that delivers category-leading heat consistency and build quality. Its three PureBlu burners feature a unique tapered design that creates a consistent flame across the entire grilling surface, with raised flame openings that prevent food debris from clogging the burner ports. The extra-large sear zone concentrates intense heat on a specific area, allowing you to get restaurant-quality crust on steaks without overheating the entire cooking surface.

The porcelain-enameled cast iron grates are thicker than those found on mid-range grills, providing superior heat retention and searing power. The FLAVORIZER bars sit above the burners and catch drippings, vaporizing them for smoky flavor while funneling grease away from the burners to prevent flare-ups. The grease management system uses a pull-out tray located under the cookbox — accessible without removing grates or flavorizer bars — for mess-free disposal.

The 641 square inch cooking area is smaller than many combo grills, but the efficient layout and even heat distribution mean you can cook more food per square inch without rotating pans. The Weber Crafted Outdoor Kitchen Collection (sold separately) adds optional accessories like a pizza stone, griddle, or Dutch oven. The side tables are sturdy enough to hold platters and seasonings, and the warming rack keeps food hot while the main grates are in use. The BILT app provides 3D assembly instructions, though some users note the app has occasional navigation quirks.

Why it’s great

  • PureBlu tapered burners for consistent flame and even heat across the grate
  • Extra-large sear zone for restaurant-quality char on steaks
  • FLAVORIZER bars add smoky flavor while preventing flare-ups

Good to know

  • Gas-only design; no charcoal side for smoky flavor purists
  • Cooking area is smaller than combo models at 641 square inches

FAQ

Can I use both the gas and charcoal sides at the same time?
Yes, most dual-fuel grill combos are designed with separate fireboxes that allow independent operation. Running both sides simultaneously can create a larger cooking zone for big gatherings, but be aware that heat spillover from the charcoal side may raise the temperature on the gas side by 50°F to 100°F depending on wind and proximity of the two chambers. Dual temperature gauges help you monitor both zones independently.
How do I clean a barbecue grill combo with both gas and charcoal chambers?
The gas side requires periodic burner cleaning to prevent clogging from grease and debris — use a wire brush on the burners and check the venturi tubes for spider webs. The charcoal side needs ash removal after each use; slide-out ash trays make this simple. Both sides benefit from a high-heat burn-off after cooking to burn away food residue. Porcelain-enameled grates should be cleaned with a brass brush to avoid damaging the coating.
Is a 34,000 BTU grill powerful enough for searing steaks?
Yes, 34,000 BTU from two main burners is sufficient for searing, though you’ll need to preheat for 10-15 minutes with the lid closed to get the grates up to 500°F-600°F. Three-burner models with 36,000+ BTU heat up faster and offer better zone control for searing one side while keeping the other zone at a lower temperature for finishing thicker cuts. If searing is a priority, look for a grill with a dedicated sear zone burner.
How much assembly time should I expect for a dual-fuel grill combo?
Plan for 1.5 to 3 hours depending on the model and your experience level. Combo grills have more components than single-fuel units because they include two separate fireboxes, dual fuel lines, and often an offset smoker. Using a cordless drill with a hex bit can cut assembly time significantly. Many buyers report that following a YouTube assembly video is easier than the paper instructions that come with most mid-range models.

Final Thoughts: The Verdict

For most users, the best barbecue grill combo winner is the Captiva Designs Dual Fuel Grill because it balances a generous 690-square-inch cooking area with porcelain-enameled cast iron grates, three main burners, and a side burner at a price that doesn’t demand a second mortgage. If you want dedicated smoking capability with a real offset firebox, grab the Oklahoma Joe’s Canyon Combo. And for pure gas grilling performance with unmatched build quality and a dedicated sear zone, nothing beats the Weber Genesis E-325.
