Overview
A battery-powered personal blender with a detachable 22-ounce cup, leak-proof travel lid and a twist-off motor base that cuts the cup's carry weight in half.
The Flex is built for blending away from an outlet, running on a 7.4V battery rather than plugging in during use. Reviewers who stick to protein shakes and juices report smooth results and an LED charge indicator that makes battery status easy to track, but several found the motor struggles with dense loads like a full cup of ice or won't run continuously while charging.
- 7.4V battery-powered motor
- 22oz detachable blending cup
- Leak-proof to-go lid
- Removable, dishwasher-friendly blade
What buyers say
From Amazon customer reviews.
Reviewers who use it for shakes and light smoothies describe it as easy to use, quiet and easy to clean, with a helpful LED battery indicator. Multiple reviewers report the battery draining fast under heavy loads like ice, and a few say the motor itself stopped charging within a few months, though NutriBullet support replaced the unit for at least one buyer. Several compare it unfavorably to a Ninja blender specifically for ice.
