Outdoor cooking has changed a lot in recent years. Instead of juggling charcoal, propane, and bulky setups, many people are turning to electric grills that still deliver authentic smoky flavors. Ninja stepped into this space with its Woodfire series, and two of the most popular models are the OG701 and OG751.
At first glance, they look almost identical — both are compact, weather-resistant, and versatile enough to grill, smoke, and air fry outdoors. But if you dig deeper, there’s one key difference that might sway your choice. Let’s break it all down.
Key Difference Between Ninja OG701 Vs OG751 Woodfire Outdoor Grills
The main difference between the Ninja Woodfire OG701 and OG751 Woodfire Pro Outdoor Grill & Smoker is the built-in thermometer. The Ninja OG751, also known as the Ninja Woodfire Pro, includes this addition, giving it an edge over the Ninja OG701 in terms of convenience and precision in cooking.

Cooking Performance
Both grills use Ninja’s Woodfire technology, which combines electric power with natural wood pellets to infuse real smoky flavor into food. They heat up quickly, handle a variety of cooking styles, and are designed for year-round outdoor use.
OG701: Perfect for everyday grilling, smoking ribs or chicken wings, or even air frying fries outdoors.
OG751: Offers the same versatility but adds convenience — the built-in thermometer monitors internal food temps and alerts you when your dish is ready.
If you’re the type who likes to “set it and forget it,” the OG751 makes outdoor cooking more relaxed. If you don’t mind checking food with a separate thermometer, the OG701 is just as capable.
Price Comparison
Ninja OG701: Generally retails between $270–$320, depending on sales and bundles.
Ninja OG751: Priced slightly higher, around $350–$400.
The OG751 usually costs about $70–$100 more. For some, the thermometer alone justifies the extra price; for others, a standalone probe does the same job at a lower cost.
