I’ve been exploring different outdoor cooking gadgets lately, and Ninja’s Woodfire Pro grills caught my attention. The promise of grilling, smoking, air frying, and even baking outdoors in one compact machine sounded almost too good to be true.
After trying both the Ninja OG751 and the Ninja OG850, I realized these two models share the same DNA but are designed for different lifestyles. If you’re debating between them, my hands-on experience should help you figure out which one fits your cooking style, space, and family needs.

Detailed Comparative Review
Design and Build
The OG751 feels compact and sleek. Its slightly lighter build makes it easier to move around, and I found it more convenient when shifting it from my patio to the balcony. The stainless-steel finish is weather-resistant, and after a few rainy days, it still looked brand new.
The OG850, however, looks more robust. It’s heavier, no doubt, but the larger body translates into more grill space. If you have room in your backyard or plan to take it camping with an RV, the weight won’t be a dealbreaker. I’d describe it as sturdy, designed for people who cook for a crowd.

Ease of Use
Both models are straightforward to set up. Plug them in, add the woodfire pellets, and you’re ready to go. The built-in thermometer on both is a lifesaver, removing the guesswork and letting me socialize while the grill takes care of the cooking.
The OG751 shines when you want variety without fuss. Switching from roasting to dehydrating was as easy as tapping a button. Meanwhile, the OG850 impressed me during a weekend barbecue with friends. I fit two whole chickens and a rack of ribs without struggling for space, something the OG751 would’ve been too small for.
Cooking Functions and Performance
Here’s where the OG751 shows its versatility. With seven functions, I was able to not just grill and smoke but also roast veggies, broil salmon, and even dehydrate fruit slices for snacks. It’s the kind of model for someone who enjoys trying out new recipes.
The OG850, though, focuses on doing fewer things but on a bigger scale. The grilling surface is 30% larger, which makes all the difference when you’re feeding a group. I grilled 10 burgers in one go without overcrowding, and the smoky flavor from the pellets came through beautifully. For me, the OG850 is more about practicality when cooking for multiple people.

Space Considerations
The OG751 fits comfortably on smaller patios or balconies. If you live in an apartment with outdoor space, this is your friend. It’s compact enough to tuck away when not in use.
The OG850 demands more real estate. It’s not oversized, but the added width and height make it more suitable for backyards, decks, or larger patios. If space isn’t a limitation, the trade-off for the bigger cooking area is worth it.
Cleaning and Maintenance
Cleaning is surprisingly manageable for both. The nonstick grill grates wipe down easily, and I appreciated that the pellet usage is minimal—just ½ cup—so there’s no mess of ashes to deal with.
The OG751 being smaller means slightly less surface area to clean, but the OG850 includes a grease tray with disposable liners, which made post-barbecue cleanup almost effortless. Between the two, I’d give the OG850 a slight edge here.

My Recommendation / Conclusion:
After using both, here’s my take:
If you’re someone who loves variety and experimenting—roasting, dehydrating, broiling, and more—the Ninja OG751 is the smarter choice. Its compact design makes it ideal for smaller spaces, and it gives you maximum cooking styles without needing a giant backyard.
But if you often host friends, cook for family gatherings, or just want more room to grill big meals, the Ninja OG850 wins. The extra 30% grill space makes a huge difference when feeding multiple people, and the convenience of the grease tray system makes cleanup less of a chore.
Personally, I lean toward the OG850 because I often cook for groups, and that extra capacity saves me time. But if I lived in an apartment or wanted to experiment with different cooking techniques, I’d definitely pick the OG751.
At the end of the day, both models deliver the signature Ninja Woodfire flavor and make outdoor cooking easier than ever—it really comes down to whether you value versatility or capacity more.
