You’re standing in the middle of a big-box store, staring at a massive hunk of steel that looks like a steam engine. It’s got two lids. One side promises the searing, smoky soul of a Texas barbecue joint. The other side offers the "I just got home from work and the kids are screaming" convenience of propane. It’s the charcoal grill gas grill combo, the supposed Swiss Army knife of the suburban backyard. It feels like a no-brainer. Why choose when you can have both?
But honestly? Most of these things are absolute junk.
I’ve spent a decade testing outdoor kitchens and burning my eyebrows off more times than I care to admit. The reality of owning a hybrid is often far messier than the glossy marketing photos suggest. You think you’re getting the best of both worlds, but without some serious vetting, you’re just buying a heavy, rust-prone headache that does two things mediocrely instead of one thing exceptionally. We need to talk about why these beasts are so tempting, where they fail, and how to actually pick one that won't end up at the local scrapyard in three years.
The obsession with the charcoal grill gas grill combo
Convenience is a hell of a drug. We live in a world where we want the weekend ritual of lighting a chimney of lump charcoal, but on a Tuesday night, we just want to sear a chicken breast in ten minutes. That’s the core appeal. Brands like Char-Griller and Oklahoma Joe’s have built entire empires on this specific craving.
The "Dual Fuel" movement isn't just about cooking; it's about real estate. If you have a small patio, fitting a dedicated Weber kettle and a three-burner Spirit side-by-side looks cluttered. A combo unit solves the footprint problem. Or it tries to.
What most people get wrong is thinking that "more features" equals "more value." In the grilling world, the opposite is often true. When a manufacturer tries to hit a $500 price point for a machine that has two fireboxes, two sets of grates, a gas manifold, and a cart, they have to cut corners somewhere. Usually, that "somewhere" is the gauge of the steel. Thin steel loses heat. It leaks air. It rusts through the moment a humid summer hits.
The engineering nightmare no one tells you about
Let’s get technical for a second, but keep it real. A gas grill needs ventilation to keep the burners from flickering out. A charcoal grill—specifically if you’re trying to use the charcoal side as a smoker—needs to be airtight to control temperatures. These two design philosophies are diametrically opposed.
When you combine them into one chassis, you often get a charcoal side that’s "leaky." You try to shut down the dampers to kill the fire, but air sucks in through the shared frame or the thin lid seals. Your charcoal keeps burning. Your "low and slow" ribs turn into "hot and charred" disasters because you can't keep the temp below 300 degrees.
Then there’s the galvanic corrosion factor. You’ve got different metals and high heat. Cheap combos use low-grade hardware to bolt the two sides together. Within two seasons, those bolts often fuse or snap. I’ve seen combos where the gas side works perfectly, but the charcoal floor has literally fallen out due to rust. It's heartbreaking.

Real-world winners: Who actually makes a good one?
If you're dead set on this, don't buy the $299 special at a pharmacy or a grocery store. You’ll regret it by July.
If you want something that actually lasts, look at the Oklahoma Joe’s Longhorn Combo. It’s heavy. That’s a good thing. Thermal mass is your friend. It uses a heavy-gauge steel that holds heat better than the tin-can stuff you find elsewhere. It also includes an offset firebox, which technically makes it a "triple threat": gas, charcoal, and a dedicated smoker.
Another interesting player is Pit Boss. They’ve leaned heavily into the "Memphis Ultimate" style, which even adds an electric glass-door smoker cabinet into the mix. Is it overkill? Probably. But for the person who wants to host a massive 4th of July party and needs to cook 40 burgers while simultaneously smoking a brisket, it’s a functional beast.
But let’s be real for a minute. If you’re a purist, you might hate these. Steven Raichlen, the guy who basically wrote the bible on barbecue (The Barbecue Bible), often emphasizes that the tool should fit the technique. A combo is a compromise. You’re trading a bit of performance on both ends for the sake of a single footprint.
The maintenance tax: It’s double the work
People forget that a charcoal grill gas grill combo requires twice the cleaning. You have the ash management of the charcoal side, which is caustic and will eat through steel if left damp. Then you have the grease management of the gas side.
On a standard gas grill, grease falls into a tray. On many combos, because of the weird shared geometry, grease traps can be hard to reach or poorly designed. If you don't clean that charcoal ash out immediately, it absorbs moisture from the air, turns into a salty paste, and destroys the metal. You're essentially maintaining two separate appliances that are welded together.
- Seasoning is mandatory. You have to treat the charcoal side like a cast-iron skillet. Coat it in oil and heat it up to create a carbonized barrier against rust.
- Cover it or lose it. You cannot leave a combo unit exposed to the rain. The complexity of the joints means more places for water to sit and rot the frame.
- Burner care. The gas burners on cheap combos are often the first to go. Look for stainless steel or porcelain-coated cast iron. Avoid the thin "tuna can" burners that flake away after a year.
Heat distribution and the "Hot Spot" problem
The gas side of a combo is usually smaller than a standalone four-burner grill. Because the firebox is cramped, you often end up with massive hot spots. The back-left corner might be 500 degrees while the front-right is barely hovering at 300.
This happens because the airflow is weird. The air has to move around two different cooking chambers. On the charcoal side, you lack the depth of a traditional Weber Kettle. The coals are often too close to the meat, making indirect cooking—the holy grail of barbecue—difficult to achieve without burning the edges of your steak.
To fix this, seasoned grillers often use a "baffle" or just get really good at moving meat around like a chess match. It’s a learning curve. If you’re used to a high-end Weber, a combo will feel like driving a bus compared to a sports car.
The price-to-quality ratio
Think about the math. A decent mid-range gas grill is $500. A decent charcoal smoker is $300. To get both in one unit for $450, the manufacturer had to find $350 in savings.
Where did that money go?
- Thinner lids: Heat escapes instantly.
- Plastic wheels: They’ll snap if you try to move the grill across a bumpy lawn.
- Cheap Igniters: You’ll be using a handheld lighter by month three.
- Lower-grade grates: Expect the porcelain coating to chip, leading to rusted food surfaces.
If you’re going to buy a charcoal grill gas grill combo, your budget really needs to start at $600. Anything less is a "disposable grill." It sounds harsh, but the landfill is full of dual-fuel combos that didn't make it to their fifth birthday.
Is the "Infrared" combo worth it?
Some modern hybrids, like those from Char-Broil, use infrared technology on the gas side. This is actually a smart move for a combo. Infrared uses a perforated plate to distribute heat evenly and prevent flare-ups. Since combo grills often struggle with airflow and hot spots, the infrared plate acts as a buffer. It makes the gas side feel more "premium" and easier to control, even if the overall build quality is mid-tier.
Actionable steps for your backyard
If you’re still convinced the combo life is for you, here is how you win:
- Check the Weight: If you can lift the entire grill with one hand, don't buy it. You want heavy, thick-gauge steel. The heavier the grill, the better it will hold a steady temperature.
- Inspect the Seals: Look at where the lid meets the body. Is there a massive gap? If so, you’ll never be able to smoke meat properly on the charcoal side. You can fix this with aftermarket fireproof felt gaskets, but you shouldn't have to on a brand-new unit.
- Prioritize the Firebox: Make sure the charcoal tray is adjustable. Being able to crank the coals up close for a sear or drop them down for slow roasting is the only way to overcome the design flaws of a square charcoal box.
- Buy a Cover Immediately: Seriously. Don't even cook your first burger until you have a heavy-duty, waterproof cover. The "death" of these grills always starts at the seams where the two sides are joined.
- Focus on the Manifold: On the gas side, check the knobs. Are they flimsy plastic or sturdy? Does the gas manifold feel secure? Leakage on the gas side is a safety hazard, not just a cooking nuisance.
Stop looking at the number of burners and start looking at the thickness of the metal. A two-burner gas side made of thick 14-gauge steel will outperform a four-burner side made of thin sheet metal every single day of the week.

If you realize a combo is too much compromise, there is no shame in the "two-grill" lifestyle. A dedicated Weber Kettle and a separate, small gas grill often cost the same as a mid-tier combo but provide vastly better results. But if space is king and you’re willing to put in the maintenance work, the right combo can indeed be the centerpiece of your patio. Just go in with your eyes open and your grease scraper ready.
