Ninja FlexFlame ProConnect Grill & Smoker Review: Can a Jack-of-All-Trades Actually Cook?

Ninja’s first full-size outdoor grill is betting that most backyard cooks don’t need a smoker, a gas grill, and a pizza oven — they need one thing that does all three without fussing. The FlexFlame ProConnect (PG305) leans hard into that bet: a propane-fired cooking platform with an electric convection fan, app connectivity, and a side-mounted Woodfire smoke box. On paper, it replaces three appliances. In practice, it’s a genuinely capable high-heat grill that pretends to be a smoker and mostly succeeds at everything except the one thing it markets hardest.

Verdict: Buy the FlexFlame if you grill weeknight burgers, host griddle breakfasts, and enjoy the convenience of an app-guided cook. Skip it if your idea of a $1,100 grill investment is smoking briskets every month.

Street price (May 2026): $1,099.99 | List price: $1,300 | Who buys it: tech-forward cooks, small-lot entertainers, space-constrained patios | Who walks: low-and-slow purists, high-volume smokers, buyers who value simplicity over feature count

Who It’s For — and Exactly Who It Isn’t

This grill is built for the cook who:

• Grills more than they smoke (midweek burgers, steaks, chicken nights),
• Loves griddling and wants one appliance instead of swapping grates
• Entertains in weekend batches (10–20 people, mixed cook demands)
• Appreciates digital precision and app conveniences
• Has limited patio space and wants to consolidate appliances
• Values fast preheat and consistent heat over authentic smoke flavor
• Is willing to pay for versatility and assembly convenience

This grill is NOT for:

• The smoke-first pitmaster. If low-and-slow briskets happen weekly, a dedicated pellet or charcoal smoker will serve you far better.
• Buyers who plan all-day smokes. The 2-cup Woodfire smoke box requires manual refilling every 45 minutes. That’s four interruptions for a typical 12-hour brisket cook.
• Cooks who need zero learning curve. The four cooking modes (Grill/Pizza, 2-Zone, Roast/Bake, Low & Slow) require understanding which burners fire on each setting.
• Budget shoppers who value included accessories. The griddle and pizza stone are sold separately; a fully kitted system runs $1,275–1,400 with accessories.
• Charcoal and offset purists. This is a propane-first, electrically-dependent platform. It won’t replicate firebox management or the ritual of tending a real fire.

The Grill in Detail

The FlexFlame is a 60-inch-wide, stainless-steel box on a wheeled cart, weighing about 130 pounds. Assembly takes roughly one hour with hand tools; the instructions are unusually clear, and Ninja has laid out hardware in step-sequence bags to avoid the typical “find a bolt you don’t need yet” frustration.

The box itself:
Double-walled heavy-duty lid with porcelain-enameled cast-iron grates. Two side tables offer workspace. Storage below the cart holds a 20-pound propane tank bracket and accessory caddy space.

The burner arrangement:
Three horizontal burners (front, middle, back) running the width of the box. Unlike traditional gas grills with individual burner controls, the FlexFlame uses a single Function Dial and Temperature Knob to manage them. Different settings fire different burner combinations:

• Grill/Pizza: All three burners on (full sear platform, 450–600°F range).
• 2-Zone: Front and middle on, back off (direct + indirect zone, 350–500°F).
• Roast/Bake: Front and back on, middle off (convection-style configuration, 300–450°F).
• Low & Slow: Middle burner only (smoking mode, advertised 200–300°F range).

The electronics:
The right-side control panel houses an LED digital readout, the Function and Temperature dials, and crucially, a trigger that activates the CyclonicHeat-IQ fan. This is Ninja’s headline: a high-velocity convection fan that circulates heat around the grill cavity and smoke underneath the food. The fan runs whenever the lid is closed; lifting the lid kills the fan. There’s no manual override — this is both an asset and a constraint.

The Woodfire smoke system:
A small smoke box mounts on the right side of the grill body, separate from the propane burners. You fill it with wood pellets (Ninja recommends their branded pellets, but users report success with any food-grade wood pellets). A button labeled “Woodfire Flavor” ignites the pellets. They burn for approximately 45 minutes on a full 2-cup load, after which you must manually refill. This is not a traditional smoker auger — it’s a supplement to the propane heat, adding smoke flavor to any cooking mode.

Temperature sensing:
Built-in thermometer (no meat probe input on the base model — that’s app-dependent via the optional ProChef wireless probe, sold separately at ~$80). The display toggles between set and actual temps until the target is reached.

The app (ProConnect):
Requires 120V outlet and Bluetooth/Wi-Fi pairing. Once connected, you monitor temps in real-time, adjust burners remotely, receive alerts when your meat hits probe temperature, and access over 50 guided recipes. The app is reliable per owner reports; Ninja also pushes firmware updates OTA.

What the marketing doesn’t emphasize:
The grill requires an outdoor electrical outlet. Ninja ships a short power cord (approximately 10 feet) — most users need an extension cord rated for outdoor use (another $20–40). This is not negotiable; the fan, ignition system, and app connectivity are 120V-dependent. If you lose power, the grill still burns propane (manual ignition option), but you lose electronic temperature control and the fan.

The Good

Heat evenness is genuinely excellent. The CyclonicHeat-IQ fan does what Ninja claims: eliminates hot spots. Multiple field tests (AmazingRibs, Smoked BBQ Source, Girls Can Grill) confirm uniform browning across wings, griddle work, and roasted vegetables. You don’t need to shuffle food or rotate platters mid-cook. On a grill platform where this was a consistent weakness for $1,100 competitors, this is a legitimate win.

Preheating and responsiveness are exceptional. 600°F in 7 minutes is verified by independent testers. The digital burner control (vs. individual manual knobs) means you dial a temp, walk away, and the motorized propane valve adjusts to hold it steady. Even in 20 mph winds, one owner reported the display held within a couple degrees.

Grilling and searing work beautifully. Wings come out crispy and evenly browned in 30 minutes. Steaks develop a proper char at 550°F. The Grill/Pizza setting gives you the raw BTU output and heat distribution of a mid-tier Weber Genesis.

Griddle cooking is genuinely convenient. Swap the grates for an optional full or half griddle, and you’ve got a breakfast station or smash-burger platform. Owners report no sticking and even heat for pancakes, eggs, and hash. This mode alone justifies the grill for entertaining-focused buyers.

Pizza capability is real if you commit. The optional pizza stone ($60) works as advertised. Owner reports: 16-inch artisan pizza in 7–10 minutes at 550°F. Is it a wood-fired oven? No. Is it a convenient pizza night upgrade over a dedicated gas grill? Yes.

App convenience is legitimate. The ProConnect app isn’t gimmicky. You can start a preheat from your phone, get pinged when your probe hits temp, and adjust burners from the patio chair.

Warranty coverage is competitive. 10-year limited warranty on burners and lid, with porcelain-enameled grates and double-walled construction suggesting durability focus. SharkNinja is also offering a free premium grill cover ($99.99 value) with purchase as of May 2026.

The Not-So-Good

The short power cord is a constant annoyance. You will need an outdoor extension cord. Ninja’s inability to ship a 20+ foot cord or include one in the box is a head-scratcher at the $1,100 price tier.

The convection fan is louder than expected. Owners describe it as a “revving jet engine” sound when it’s cycling air. It doesn’t bother everyone, but night cooks or noise-sensitive neighbors may object. You can’t turn it off without opening the lid.

Grease tray cleaning is mandatory and messy. The drip pan underneath requires emptying after fatty cooks (ribeyes, chicken wings). It’s simple enough, but it’s a ritual you’d avoid with a traditional offset or pellet smoker.

No integrated light or tool hooks. AmazingRibs called this out directly: for a $1,100 grill, a simple LED under the lid and a couple hook mounts on the side shelves feel like omissions.

Accessories are aggressively separate purchases. The griddle half ($120–150), full griddle ($180–220), pizza stone ($60), expanded smoke rack ($40), and storage caddy ($30–50) add $300–500 to the core grill cost. Bundled pricing via Ninja is better, but MSRP-to-MSRP, the FlexFlame + accessories look more expensive than buying a dedicated gas grill.

The 2-cup Woodfire smoke box is really a 45-minute timer. For anything longer than a quick smoke cycle, you’ll interrupt to manually refill. It’s not a dealbreaker, but it’s not the “set and forget” system some marketing suggests.

The Dealbreaker: Low & Slow Smoking Is Compromised

This is the critical failure point, and it needs to be stated plainly:

You cannot reliably hold 200°F on this grill in warm weather.

Ninja’s official documentation and engineer responses (captured in AmazingRibs’ review) confirm: if outdoor ambient temps are above 60°F, the Low & Slow setting will not dip below 250°F. The reason: the CyclonicHeat-IQ fan is a double-edged sword. It’s essential for even heat distribution and fast cooking, but it’s fundamentally incompatible with the low-temperature dwell time required for traditional low-and-slow smoking.

What this means in practice:

• A traditional 225°F, 12-hour brisket becomes a 250–270°F, 8–10 hour cook. Faster, yes. Same result? No. The meat cooks out before developing proper bark.
• Smoke flavor is lighter than a dedicated pellet or charcoal smoker. Multiple field testers reported smoke rings on FlexFlame ribs were visibly shallower than side-by-side cooks on dedicated smokers.
• The Woodfire smoke box refill requirement (every 45 minutes) turns a “set it and forget it” smoke into an attended cook. You’ll refill 3–4 times for an extended brisket.
• Girls Can Grill’s competitive pitmaster reported: “I’ve smoked multiple briskets using the low & slow setting, and they’re so good, you can’t even tell they came off of a gas grill,” but this is because she’s using the FlexFlame for flavor-enhanced low-temp roasting, not traditional smoking.

The $100 Brisket Test: Would I trust a $100 packer on this thing?

No. Not as your primary cooker for that cook.

Here’s why: A 14-pound prime packer is unforgiving. A full brisket at 225°F on a proper pellet or charcoal smoker takes 12–14 hours. On the FlexFlame’s Low & Slow setting (running closer to 250–270°F due to ambient heat and the fan), you’re looking at 8–10 hours, which is fast enough that you’ll risk overshooting the stall window. More critically, the convection fan means the top surface dries out faster than the bottom gets tender. The smoke flavor won’t be deep enough to justify the cooking method.

Technique adjustment for the FlexFlame: If you’re committed to smoking on the FlexFlame, treat it as a high-heat roaster with smoke supplementation, not a low-and-slow platform. Cook at 250–275°F (not 225°F), manually refill the Woodfire smoke box every 45 minutes, and pull at probe-tender (203°F internal) around the 8–10 hour mark. You’ll get a respectable smoked brisket. It won’t have the bark and ring of a dedicated smoker. But it’ll be edible, and you’ll have tested the grill’s true capability.

Honest off-ramp: If your primary intent is smoking, buy a dedicated pellet or charcoal smoker. The FlexFlame will disappoint you on the one cook it markets hardest.

Everyday Cooking and Weekend Entertaining

Weeknight grilling (steaks, chicken, burgers):
The FlexFlame excels here. Preheat to 550°F, sear for 2–3 minutes per side, pull at your target temp. The digital readout holding steady and the fan ensuring no flare-ups mean consistent results night after night. Faster than a charcoal grill, more forgiving than a cheap gas grill, and the app’s optional monitoring removes guesswork.

Griddle work (breakfast, smash burgers, stir-fry):
If you invest in the griddle accessory, this is a revelation. One owner reported using the griddle “nearly every day” for eggs, bacon, hash, and cheese steaks. The even heat and grease drain design simplify cleanup.

Roasting (whole chickens, root vegetables, potatoes):
The Roast/Bake setting (front and back burners, middle off) creates an indirect zone. Results are fast and even — one tester reported whole chickens roasting 35% faster than traditional methods, with crispy skin and juicy meat.

Pizza:
With the optional pizza stone, you’ll need some skill. Frozen pizzas are forgiving (7–10 minutes, 550°F). Fresh dough requires watching. But owners report genuine pizza-night capability.

Smoking (short cycle, 4–6 hours or less):
Wings at 250–300°F with the Woodfire button engaged work well — smoky flavor, crispy skin, done in 30–45 minutes. Pulled pork at 250°F for 6 hours works. The smoke flavor is present and respectable. The time limit is the constraint, not quality.

The Competition — Gas Grills in This Price Band

At $1,100 street price, the FlexFlame competes directly with propane-fired grills. Here are the real rivals:

Weber Genesis E-325 ($949)

• Cooking surface: 669 sq in (larger than FlexFlame’s 424)
• Burners: Three main burners, one side burner (FlexFlame has no side burner)
• Control: Manual individual burner knobs (vs. FlexFlame’s digital preset modes)
• Heat range: Up to 600°F, same as FlexFlame
• Features: No smoke capability, no app, no convection fan
• Warranty: 10-year (burners and firebox), 5-year on lid
• Owner pattern: Praised for simplicity, durability, and sear consistency. No complaints about heat evenness because you manage it manually.
• Honest trade: E-325 is $150 cheaper, 245 sq in larger, and requires zero electricity. You lose app convenience, convection fan evenness, and all the mode-switching. If your primary cook is grilling steaks and burgers, the E-325 is the better value. If you want griddle versatility and app monitoring, FlexFlame wins.

Weber Genesis E-335 (~$1,050–1,100)

• Cooking surface: 669 sq in (same as E-325)
• Burners: Three main burners + dedicated sear burner (front right, independent control)
• Control: Manual knobs (sear burner is the upgrade over E-325)
• Heat range: Up to 700°F on sear burner, 600°F main grate
• Features: No smoke, no app, no griddle without separate purchase
• Warranty: 10-year (same as E-325)
• Owner pattern: Sear burner owners love the ability to reverse-sear steaks (sear at high heat, then move to indirect). Grilling performance is essentially E-325-level.
• Honest trade: E-335 and FlexFlame are price-matched at ~$1,100. E-335 gives you a true sear burner and larger surface; FlexFlame gives you app control, convection fan evenness, griddle mode, and smoke supplementation. If you sear steaks twice a week and grill only, E-335 wins. If you entertain with mixed menus (griddle, pizza, grill), FlexFlame wins.

Char-Broil Professional Series (~$1,100–1,200)

• Cooking surface: 540 sq in, four burners
• Control: Digital control panel with preset temps (similar to FlexFlame’s concept)
• Features: Stainless steel grates, electronic ignition, no app, no convection fan
• Warranty: Limited (typically 2–3 years, vs. FlexFlame’s 10)
• Owner pattern: Mid-tier reviews; performs solidly but lacks the fit-and-finish of Weber. Warranty reputation is weaker than Ninja or Weber.
• Honest take: Cheaper warranty and less brand trust. If budget is the only constraint and warranty matters less to you, Char-Broil is functional. But most buyers in this tier opt for Weber or Ninja for durability and resale.

Value Table (Gas Grills Only)

The honest bottom line on gas grills:

• Best pure searing: Weber E-335 (dedicated sear burner wins at technique).
• Best all-around versatility: Ninja FlexFlame (app, fan, griddle mode, smoke).
• Best simplicity + value: Weber E-325 ($150 cheaper, more cooking surface, zero complexity).
• Budget play: Char-Broil Pro (same price as FlexFlame, larger surface, weaker warranty).

Propane vs. Pellet vs. Charcoal — Which Fuel Wins at What

The FlexFlame is propane-fired. But a buyer at the $1,100 mark needs to understand when propane is the right choice and when another fuel would serve the mission better.

Propane (Ninja FlexFlame) vs. Pellet Smoker (Traeger Ironwood 650)

The Cook: Seared Steaks (High Heat)

• Propane (FlexFlame): 600°F in 7 minutes, sear a 1.5-inch ribeye in 3 minutes per side, perfect crust. Digital temp control holds steady. Winner: Propane by a wide margin. Pellet smokers max at 500°F and take 15+ minutes to preheat.
• Why Propane Wins: Direct flame contact, instant heat response, burner-level control. A propane grill is purpose-built for high-heat searing.

The Cook: 12-Hour Smoked Brisket (Low & Slow)

• Propane (FlexFlame): Cannot reliably hold 200°F in warm weather (floors at ~250°F). Cook time is 8–10 hours. Smoke flavor is supplemental (light ring). Woodfire smoke box requires four manual refills. You’re attending the cook.
• Pellet (Ironwood 650): Holds 225°F all day on a single 20-pound hopper fill. Deep smoke ring, bark, authentic low-and-slow results. Set and forget for 12 hours.
• Winner: Pellet by a landslide. If your primary cook is smoked brisket, propane is a poor substitute.

The Cook: Roasted Whole Chicken (Indirect, Fast)

• Propane (FlexFlame): 2-Zone mode, 375°F indirect, chicken done in 45 minutes with crispy skin. Convection fan ensures even browning.
• Pellet (Ironwood): Same temps, same timing, same results. Pellets add subtle smoke flavor (optional).
• Winner: Tie (slight edge to FlexFlame for speed). Both handle this equally well. Propane is marginally faster; pellets add optional smoke.

The Cook: Griddle Breakfast (Smash Burgers, Eggs, Pancakes)

• , Propane (FlexFlame): With griddle accessory, flat-top cooking at precise heat. Stovetop-like experience.
• Pellet (Ironwood): No griddle mode; you’d need a separate griddle accessory on the grates.
• Winner: Propane (FlexFlame). Griddle is natively built into FlexFlame’s design; pellet grills require third-party add-ons.

The Cook: Pizza (High Heat, Short Duration)

• Propane (FlexFlame): 550°F, 16-inch pizza in 7–10 minutes. Grill/Pizza mode is purpose-built.
• Pellet (Ironwood): Can reach 500°F, pizza takes 12–15 minutes. Slower, not ideal.
• Winner: Propane (FlexFlame). Propane’s speed advantage is real for pizza.

Verdict on Propane vs. Pellet:

• Choose Propane (FlexFlame) if: Your cook rotation is 60% grilling, 20% roasting, 10% griddle, 10% light smoking.
• Choose Pellet (Traeger/Weber) if: Your cook rotation is 60% smoking, 30% roasting, 10% grilling (and you accept slower preheat for smoking excellence).
• Honest take: These are different tools for different missions. Propane is the weeknight grill. Pellets are the weekend smoker. A buyer should pick based on which cook happens more often in their kitchen.

Propane (Ninja FlexFlame) vs. Charcoal (Kettle/Offset)

The Cook: High-Heat Seared Steak

• Propane (FlexFlame): 600°F, 7-minute preheat, precise temp control, zero flare-ups (fan suppresses them).
• Charcoal (Kettle): 600°F possible (chimney stack and open vents), 20–30 minute preheat, managing air intake for exact temp is an art. Single flare-up can ruin a sear.
• Winner: Propane decisively. Charcoal requires skill; propane is plug-and-play.

The Cook: 12-Hour Smoked Brisket

• Propane (FlexFlame): 250°F minimum in warm weather, 8–10 hours, light smoke.
• Charcoal (Offset Smoker): 225°F all day, 12–14 hours, deep smoke from live firebox. Bark and ring are authentic because you’re burning wood directly.
• Winner: Charcoal by a landslide. Offset smokers exist because low-and-slow smoking is their native function. Propane is a compromise.

The Cook: Roasted Vegetables (Indirect, Medium Heat)

• Propane (FlexFlame): 375°F, even heat, done in 20 minutes, crispy edges.
• Charcoal (Kettle in 2-zone): 375°F indirect, same timing, same result. Charcoal adds subtle flavor if you add a wood chunk.
• Winner: Tie (slight edge to Propane for consistency). Propane holds temp tighter; charcoal drifts slightly.

The Cook: Weeknight Burger or Hot Dog (Quick, High Heat)

• Propane (FlexFlame): Light burner, 400°F, 10-minute preheat, done in 10 minutes total.
• Charcoal (Kettle): 400°F, 20–30 minute preheat (coal lighting, building temp), done in 10 minutes total. Total time: 30–40 minutes.
• Winner: Propane decisively. For weeknight convenience, propane is unbeatable.

Verdict on Propane vs. Charcoal:

• , Choose Propane (FlexFlame) if: You value speed, consistency, and weeknight convenience. You’ll accept lighter smoke flavor.
• Choose Charcoal (Kettle/Offset) if: You enjoy the ritual of fire management, want authentic smoke flavor, or are willing to spend 30 minutes on preheat for superior low-and-slow results.
• Honest take: Propane is the modern convenience play. Charcoal is the purist play. They’re not in direct competition — they appeal to different cook philosophies.

The Three-Fuel Comparison at a Glance

Long-Term Ownership: What a Decade Actually Costs

What Breaks First (In Order of Likelihood)

1. The electrical components (fan motor, ignition, control board) — Outdoor exposure and voltage sags will eventually stress them. Best case: 5–7 years before a part needs replacement. Ninja’s 10-year warranty covers this; out-of-pocket replacement parts run $150–300.
2. The propane valve motor (automated burner control) — Ninja’s system relies on a motorized valve to adjust flame. After 3–4 years of use, drift is possible. Warranty repair: $0. Out of pocket: ~$200.
3. The porcelain-enameled cast grates — These are durable, but impacts and thermal shock can crack or chip them. Replacement: ~$80–100 per pair.
4. The Woodfire ignitor wire and box seals — The smoke box will eventually need re-sealing gaskets or ignitor maintenance. Low-cost items ($20–50).
5. The propane hose and regulator — Standard wear item, not unique to Ninja. Replacement every 5–8 years (~$40–60).

Warranty Service Reputation

Early reports from Best Buy and Home Depot reviews are positive. Ninja’s customer service phone line (1-800-365-0135) has responded to complaints with solutions and hasn’t shown patterns of denial. One user on Home Depot reported a return within the return window with no friction.

No widespread warranty-denial clusters reported yet (product is only 4 months old). Assuming Ninja’s reputation for kitchen appliances carries over, expect professional service. Outdoor gear historically has longer wait times for parts; budget 2–4 weeks if something fails.

10-Year Cost-of-Ownership Estimate

This is a planning estimate based on researched part and accessory prices, not a tested forecast.

Year 1 (New):

• Grill: $1,100
• Extension cord (rated for outdoor use): $30
• Propane tank rental/fill (annual budget): $50
• Grill cover (included now, ~$100 value): Free,
• Year 1 Total: $1,180

Years 2–5 (Annual Maintenance):

• Propane fills: ~$50/year × 4 = $200
• Pellets (experimental cooks, seasonal use): ~$100/year × 4 = $400
• Accessory investments (optional full griddle, pizza stone, expanded rack): $300 (one-time, amortized)
• Annual covers and care: ~$20/year × 4 = $80
• Years 2–5 Subtotal: $980

Years 6–10 (Higher Maintenance Risk):

• Propane fills: $50/year × 5 = $250
• Pellets: $100/year × 5 = $500
• Likely component replacement (fan motor, ignitor, seals, gaskets): ~$300 (one-time, warranty or out-of-pocket split)
• Grate replacement (one pair, ~$100): $100
• Propane valve or regulator replacement: $200
• Annual care and covers: $20/year × 5 = $100
• Years 6–10 Subtotal: $1,450

Total 10-Year Estimate: $3,610

This breaks down to $361 per year or $0.85 per grilling day (assuming 425 grill days over 10 years).

My Maintenance Regimen

• Hot-brush the grates after every cook (soak in hot water, wire brush, done in 60 seconds).,
• Empty the grease tray after fatty cooks. Don’t let it overflow and drip on the burners.
• Inspect the propane hose and regulator annually for cracks or corrosion. Replace if any visible damage.
• Cover the grill year-round (Ninja’s included cover or weatherproof option). Sun and rain age stainless steel and accelerate electronic corrosion.
• Check the electrical components quarterly — look for corrosion on the plug, moisture in the control box, or burnt smells. Address immediately.
• Run a propane-only ignition test monthly (manually light the burners with a match). This ensures you have a failsafe if electronics fail.
• Steam-clean the griddle after use (if you have the accessory) — high-heat steam burst, wipe down, dry.

When to Buy — The Price Pattern

Current Status (May 2026):
The FlexFlame launched at $1,300 MSRP in February 2026. It’s now settled at $1,099.99 (15% discount) across Amazon, Best Buy, and SharkNinja’s official site. This happened in three phases:

• March 2026: Big Spring Sale discount to $1,099.99.
• April 2026: Post-Easter promotion held the $1,099.99.
• May 2026: Continued at $1,099.99, with free $99.99 premium cover offer.

The Patient-Buyer Play:
Ninja is offering the cover incentive instead of further price cuts, suggesting they’re confident in $1,100 as the floor. Black Friday/Cyber Monday 2026 may push another 10% off if the grill doesn’t hit volume targets. But given that it’s only been on market for 4 months, I’d expect $1,099.99 to hold until fall.

Best time to buy: Now, or wait for Black Friday (November 2026). The free cover sweetens the deal. If you’re not in a rush, late October might see clearance pressure, but I wouldn’t count on it.

Avoid: The $1,300 MSRP. No retailer is holding that line; it’s a negotiation reference point only.

Long-Term Ownership: What a Decade Actually Costs

Frequently Asked Questions

Q1: Can I use this on a natural gas line instead of propane?, 
A: No. The FlexFlame is propane-only. Ninja has no natural gas conversion kit. If your home runs natural gas, you’ll need to maintain a separate propane tank (standard outdoor setup in propane-only areas).

Q2: Do I need to plug this in during propane-only operation?
A: No, but you’ll lose precision and convenience. Without 120V power, you can manually ignite the burners with a match, but the electronic temperature control won’t work. The fan won’t run. The app won’t sync. Propane will still flow and burn. This is a failsafe, not a primary mode.

Q3: Can I swap this grill indoors or under a covered patio?
A: No. This is an outdoors-only appliance. It requires continuous ventilation for the exhaust and ideally overhead clearance (no roof or enclosed ceiling). Even under a covered patio, carbon monoxide buildup risk is real. Treat it as a full-open-air grill.

Q4: How does the app work without Wi-Fi?
A: ProConnect uses Bluetooth (range: ~50 feet) as primary, with optional Wi-Fi for remote access outside Bluetooth range. Most owners operate via Bluetooth from the patio. Wi-Fi is useful if you want to start a preheat from inside the house or monitor from the garage. Bluetooth alone is reliable per user reports.

Q5: What’s the difference between the PG305 (ProConnect) and the PG301/PG302 (non-ProConnect models)?
A: The PG301 and PG302 are older, non-app versions. The PG305 added the ProConnect app integration, improved the control panel, and refined the burner sequencing. If you’re shopping new in 2026, the PG305 is the current model. Earlier versions are available used or clearance; if price is your only constraint, they’re still solid, but you’ll miss app convenience.

Q6: Are Ninja’s wood pellets required, or can I use any brand?
A: Any food-grade wood pellets work. Ninja’s are rebranded Bear Mountain pellets. Hickory, applewood, mesquite, cherry — all burn fine. Ninja doesn’t lock you into their brand, though they bundle two sample bags with the grill.

Q7: How loud is the fan really?
A: One owner described it as “a revving jet engine.” It’s noticeable. If you grill at 10 PM in a quiet neighborhood, your neighbors will hear it. During the day, especially with a crowd, it’s just part of the ambient noise. If quiet operation is critical, this grill isn’t for you.

Final Verdict

The Ninja FlexFlame is a genuinely capable platform that delivers on four of its five promises and falls short on the fifth in a way that matters if that fifth thing is your primary use case.

Buy the FlexFlame if:

• You grill 2–3 times per week and want to add weeknight griddling and monthly pizza nights without buying three appliances.
• You value app convenience and digital precision over manual burner control.
• Your patio space is limited and consolidation is a real problem.
• You’re willing to accept “good enough” smoke flavor instead of “authentic” for the sake of versatility.
• You entertain in batches and want one cooker that handles mixed menus (grilled mains, griddle sides, roasted vegetables, pizza).

Skip the FlexFlame if:

• Your primary cook is smoking whole packer briskets, and you do it monthly or more.
• You value simplicity and manual control over app-based convenience.
• You’re unwilling to manually refill a Woodfire smoke box every 45 minutes for smoking.
• You have unlimited patio space and would rather buy a dedicated gas grill + pellet smoker (better performance in each category, though more appliances to maintain).
• You’re a charcoal purist and see propane + electricity as a dealbreaker.

The practical choice: If you grill more than you smoke, the FlexFlame’s versatility is legitimately valuable. If you smoke more than you grill, a dedicated pellet or charcoal smoker at the same price is the better investment. There’s no bad choice here — it’s about honest self-assessment of how you actually cook.

At $1,100 with the included cover and current street pricing, the FlexFlame is fairly valued for what it is. It’s not the revolutionary all-in-one some marketing suggests. It’s a high-quality, feature-rich gas grill that dabbles in smoking and pizza, with app integration that actually works. That’s enough.
