Outdoor cooking has come a long way from traditional charcoal grills and bulky propane setups. Today, smart outdoor grills like the Ninja OG751 Woodfire Pro and the Ninja OG850 Woodfire Pro XL offer the authentic smoky flavors of wood pellets combined with the convenience of electric power. Both models pack the brand’s signature Woodfire Technology, allowing you to grill, smoke, air fry, and bake outdoors without the mess of charcoal or the hassle of propane tanks.
At first glance, the OG751 and OG850 seem nearly identical, but there are some important differences in size, functionality, and cooking capacity that may determine which one is the right fit for your backyard, balcony, or tailgating setup. After carefully comparing both, I’ve broken down their features, pros, and cons to help you make an informed choice.
Key Difference Between Ninja OG751 vs OG850
The Ninja OG751 is a 7-in-1 outdoor grill with a built-in thermometer, giving you more versatility for different cooking styles, from grilling and smoking to roasting, dehydrating, and broiling. It’s also slightly lighter and more compact, making it a great option for smaller spaces.
The Ninja OG850, on the other hand, is the Pro XL model, designed with 30% more cooking capacity (180 sq. in. vs 141 sq. in.) large enough to handle two whole chickens, a full brisket, or 10 burgers at once. While it only lists 4-in-1 functionality (Grill, BBQ Smoke, Air Fry, Bake), its real strength is in handling bigger batches for entertaining.
In short, choose the OG751 if you want more cooking functions and flexibility, and the OG850 if you need extra cooking space for family gatherings or parties.

Detailed Comparison Analysis: Tried & Tested
Design & Build Quality
Both the OG751 and OG850 sport a stainless steel build with weather-resistant design, making them safe to store outdoors year-round. The OG751 comes in a grey finish, while the OG850 has a darker blue/grey tone for a slightly bolder look.
- The OG751 is lighter (30.6 lbs) and more compact, making it easier to move around, ideal for balconies or smaller patios.
- The OG850 is heavier (38.9 lbs) and bulkier, but that’s because of its larger cooking chamber and added grilling surface.
Both include Ninja’s exclusive Woodfire Pellets, designed for adding smoke flavor without serving as the actual power source. Since these grills are electrically powered, you don’t need to worry about flareups, propane tanks, or charcoal mess.

Cooking Performance
Ninja OG751 Woodfire Pro
The OG751 impressed me with its 7-in-1 versatility. Besides the core grilling and smoking functions, I found the roast and dehydrate modes useful for outdoor side dishes. The broil mode delivered restaurant-style searing, which is rare in portable grills. Its built-in thermometer takes the guesswork out of cooking, automatically alerting you when food reaches the desired temperature.
Ninja OG850 Woodfire Pro XL
Where the OG850 really shines is capacity. With 180 sq. inches of cooking space, I was able to grill two racks of ribs at once; something the OG751 couldn’t handle as easily. It’s designed for entertaining, with enough room to cook for a crowd without cycling batches. Although it only lists 4 functions, it still nails grilling, smoking, air frying, and baking with authentic smoky flavor.
Ease of Use
Both models are plug-and-play electric grills, making them easier to use than propane or charcoal setups. Ninja’s Woodfire Technology works seamlessly: just add ½ cup of pellets, select your function, and you’ll get consistent smoky results.
The OG751’s extra functions (like dehydrate and broil) make it better for culinary enthusiasts who want to experiment. Meanwhile, the OG850’s larger cooking surface means you don’t need to constantly rotate food when cooking for groups.
