More from this brandAll Ninja countertop blendersOverview
A 1600 peak-watt countertop blender built around a twist-lock tamper that pushes ingredients into the blades while it runs. It ships with a 34 oz pitcher plus 24 oz and 18 oz to-go cups, aimed at smoothies, frozen drinks and thicker blends like nut butter.
Auto-IQ programs handle the pulse and pause timing automatically. Several buyers compare it favorably to much pricier blenders on smoothie duty, though more than one flags the noise level as a real tradeoff.
- 1600 peak watts, smartTORQUE motor
- 34 oz pitcher plus two to-go cups
- 5 functions including spreads and bowls
- Auto-IQ blend programs
Who it's for
Fits one or two person households wanting smoothies, protein shakes or bowls without buying a full-size pitcher blender. Anyone sensitive to blender noise, or needing to blend early morning without waking a household, should weigh the volume complaints before buying.
Pros and cons
- Twist tamper avoids stopping to shake or stir
- Compact pitcher and cup sizes suit one or two servings
- Included cups double as grab-and-go containers
- Loud enough that several owners wait for others to be awake
- Base has been reported to loosen and drip
Performance notes
Auto-IQ programs cycle blend and pulse patterns on their own, so the main manual input is choosing a function and twisting the tamper as needed.
