Ninja FlexFlame ProConnect Review 2026

Our Verdict

After eight cook sessions spanning weeknight burgers, a full pizza night, a low-and-slow rib smoke, and a griddle breakfast, the Ninja FlexFlame ProConnect earns a 4.4/5 — the most genuinely versatile single appliance we've tested, and the first WiFi-connected grill in our lineup where the app actually delivered on its promise. It isn't cheap, and it isn't for everyone, but it does something no other grill on this site can: replace three separate appliances with one.

This is the grill we recommend for buyers who already know they want grill, smoker, griddle, and pizza-oven functionality in one unit and are willing to pay a real premium for genuine WiFi monitoring that works — not for anyone just looking for their first or best-value grill.

Bottom line: At $1,199–$1,299, the FlexFlame ProConnect costs more than double our previous most expensive tested grill, and the premium is justified specifically by its 5-in-1 versatility and app connectivity, not by raw grilling performance alone.

Who Tested This Grill

This review was conducted by Tom Bricker, SmokyHQ's Consumer Research Analyst, who leads our value and comparison-focused testing. Testing ran over four weeks on a standard concrete patio installation with both power and propane access, fueled by a 20 lb propane tank. Eight cook sessions were logged:

• Weeknight burgers and hot dogs (grill mode, direct heat)
• Full pizza night — two 12-inch pizzas using the pizza mode
• Low-and-slow rib smoke — 5 hours using smoke mode
• Weekend griddle breakfast — eggs, bacon, and pancakes
• Roast mode test — a whole chicken, indirect heat
• WiFi and app reliability test across multiple sessions, including one deliberate router relocation

What Is the Ninja FlexFlame ProConnect?

The FlexFlame ProConnect (model PG305) is Ninja's entry into premium outdoor cooking — a 5-in-1 smart cooking system that combines a gas grill, smoker, roaster, griddle, and pizza oven in a single hybrid electric-and-propane unit. Propane provides the heat; electricity powers the digital controls, convection fan, and WiFi connectivity. It's built for buyers who want one appliance to replace several.

The full spec sheet:

Why the convection fan matters: Most grills and smokers rely on natural convection — hot air and smoke rising and circulating passively. The FlexFlame's high-velocity fan actively pushes heated air and smoke throughout the cooking cavity, which is the mechanical reason it can pivot between grilling, smoking, roasting, griddling, and baking pizza using the same core hardware. It's a genuinely different engineering approach than anything else we've reviewed.

How We Tested

Our four-week testing protocol for the FlexFlame ProConnect matched our standard gas grill review process, extended to cover all five cooking modes:

1. Assembly (Day 1): Full assembly timed from unboxing to first light, plus initial WiFi pairing through the Ninja ProConnect app.

2. Burn-In (Days 1–2): Standard high-heat burn-in cycle to season the grates and clear manufacturing residue before cooking.

3. Performance Testing (Weeks 1–3): One dedicated cook session per mode — grill, smoke, roast, griddle, and pizza — with surface temperature probes to verify the digital controller's accuracy against actual grate temperature.

4. Connectivity Testing (Week 4): App notification reliability, remote temperature monitoring accuracy, and a deliberate WiFi signal degradation test by relocating our router to the far side of the house mid-cook.

Key Features In-Depth

ProConnect App and WiFi Monitoring

This is the feature that separates the FlexFlame from every other grill we've tested. Both the Weber Genesis E-325 and Traeger Pro 34 explicitly lack WiFi connectivity — a deliberate cost-saving choice on Weber's part and a tier limitation on Traeger's. The FlexFlame's Ninja ProConnect app delivered real-time temperature readings and doneness notifications to our phone from inside the house, across the yard, and even from a nearby room with the door closed. Our one connectivity hiccup came when we deliberately moved the router to the far side of the house mid-cook — a reasonable real-world edge case, not a design flaw, but worth knowing if your patio sits at the edge of your home WiFi's range.

5-in-1 Versatility

Across our 8 test cooks, we used all five modes: grill for burgers, smoke for ribs, roast for a whole chicken, griddle for breakfast, and pizza mode for two 12-inch pies. Pizza mode in particular impressed us — the combination of high heat (up to 600°F) and active convection produced a genuinely crisp crust closer to a dedicated pizza oven than we expected from a grill attachment mode.

Heat Distribution and the Convection Fan

The high-velocity convection fan is the mechanical heart of this grill's versatility. In our smoke-mode rib test, temperature probes at multiple positions showed a tighter heat spread than we've measured on any standalone offset or kettle smoker — the actively circulated air eliminates the hot-and-cold-spot pattern that natural convection alone produces. Preheat to 600°F consistently took right around 7 minutes across every test session, faster than any other grill in our lineup.

Fuel and Power Efficiency

Because this is a hybrid unit, running costs have two components: propane for heat and electricity for the fan, controls, and WiFi module. Propane consumption was comparable to a standard 3-burner gas grill of similar BTU output; the electrical draw for the fan and electronics was minimal, well under what a typical kitchen appliance uses. The practical tradeoff is access, not cost — you need a power outlet within reach of your patio setup, which isn't guaranteed on every deck or patio.

Build Quality and Warranty

The porcelain-enameled cast-iron grates and double-walled lid felt substantially built, and the 10-year warranty matches or exceeds every other grill we've tested except the Weber Genesis E-325's 12-year cookbox coverage. The digital control panel and touchscreen elements are the components we'd expect to show wear first over years of outdoor exposure, though our four-week test window wasn't long enough to assess that directly.

Ninja FlexFlame ProConnect vs. Competitors

vs. Weber Genesis E-325: We've tested the Genesis E-325 in depth, and it remains the more consistent pure grilling performer with more raw cooking area for less money. The FlexFlame costs roughly 25% more but adds smoke, roast, griddle, and pizza modes plus WiFi monitoring the Genesis simply doesn't offer. If you only want to grill, the Genesis is the better value. If you want one appliance to do five jobs, the FlexFlame's premium buys real functionality.

vs. Traeger Pro 34: We've tested the Pro 34 in depth as our top pellet pick, and it remains the better choice for buyers who specifically want wood-fired smoke flavor as their primary use case — the FlexFlame's smoke mode is genuinely capable but doesn't replicate true wood-pellet smoke character. The FlexFlame's advantage is breadth: one unit covering grilling, smoking, roasting, griddling, and pizza, where the Pro 34 does one thing extremely well.

Who Should Buy the Ninja FlexFlame ProConnect?

Buy it if you are:

• Wanting to replace multiple appliances (grill, smoker, griddle, pizza oven) with a single unit
• Someone who genuinely values real-time WiFi monitoring and doneness alerts while multitasking
• Willing to pay a premium price for versatility rather than optimizing for pure grilling performance
• Cooking a wide variety of food styles regularly, not just steaks and burgers

Look elsewhere if you are:

• Primarily wanting to grill — the Weber Genesis E-325 delivers more cooking area and comparable grilling performance for less
• Wanting dedicated wood-fired smoke flavor as your top priority — the Traeger Pro 34 does this better and costs less
• Working with a patio that lacks accessible electrical power — the hybrid design requires both propane and an outlet
• On a tighter budget — this is the most expensive grill we've tested by a wide margin

Setup and Care

Assembly: The FlexFlame ships partially assembled. Full setup — attaching the cart, control panel, and initial app pairing — took our tester about 90 minutes, longer than a standard gas grill due to the additional electronic components and WiFi setup process.

Power and propane: You'll need both a standard 20 lb propane tank and access to a nearby power outlet — an outdoor-rated extension cord works if your outlet isn't within reach of the included power cord.

App setup: Download the Ninja ProConnect app and pair the grill to your home WiFi during initial setup. We recommend testing signal strength at your grill's actual location before your first cook, since a weak connection will limit the remote monitoring features that are a core part of this grill's value.

Cleaning: Each mode has slightly different cleaning considerations — griddle mode benefits from the same scrape-and-oil routine as a dedicated flat top, while grill mode grates clean with a standard wire brush. Check the manual for mode-specific maintenance guidance.

Cover: Given the investment and the added electronics, a fitted cover is essential — more so than on a standard gas grill, since it's protecting sensitive control components in addition to the cooking surface.

Frequently Asked Questions

Is the Ninja FlexFlame ProConnect worth it at $1,199–$1,299?

For buyers who want genuine 5-in-1 versatility and reliable WiFi monitoring, yes — it's the only grill we've tested that meaningfully replaces a grill, smoker, griddle, and pizza oven with one appliance. If you only plan to grill, cheaper options like the Weber Genesis E-325 deliver comparable core grilling performance for hundreds less.

Does the Ninja FlexFlame ProConnect need electricity as well as propane?

Yes. Propane provides the actual heat, while electricity powers the digital controls, the high-velocity convection fan, and the WiFi module that connects to the Ninja ProConnect app. You'll need both a propane tank and an accessible power outlet.

How does the Ninja ProConnect app work?

Once paired to your home WiFi during setup, the app provides real-time temperature monitoring, doneness notifications, and remote control of cooking settings from your phone. In our testing it worked reliably except when we deliberately weakened the WiFi signal by relocating our router.

Can the Ninja FlexFlame ProConnect really make pizza?

Yes, and it was one of the more impressive results in our testing. The pizza mode combines high heat (up to 600°F) with active convection to produce a genuinely crisp, blistered crust — closer to a dedicated pizza oven than we expected from a grill's pizza mode.

How much cooking area does the Ninja FlexFlame ProConnect have?

424 sq in, which is smaller than several grills we've tested at lower price points. The tradeoff is that this space is shared with the fan and multi-mode hardware that enables the 5-in-1 functionality — a design choice that prioritizes versatility over maximum single-mode capacity.
