Overview
The Ninja BN751 Professional Plus DUO is a 1400 peak watt countertop blender with a 72 ounce Total Crushing pitcher and two 24 ounce to go cups, aimed at households making smoothies and frozen drinks in both large and single serve batches.
Auto-iQ handles the pulse and blend timing for three preset programs, smoothies, frozen drinks and nutrient extraction, so the user does not have to guess how long to run the motor. The DUO pairing of a big pitcher with travel cups is the practical reason to pick this over a single container blender. Ninja positions it as an upgrade over its original Professional Blender on operating wattage.
- 1400 peak watts, Total Crushing blade system
- 3 Auto-iQ preset programs
- 72 oz pitcher, 64 oz max liquid capacity
- Two 24 oz to go cups with spout lids included
Who it's for
Fits a family or daily smoothie drinker who wants both a large batch pitcher and a grab and go cup from the same base. Less useful for someone who only ever blends single servings and does not need the 72 ounce pitcher.
