A capable cordless blender for single smoothies away from an outlet, though a battery that needs frequent recharging and at least one overheating report are worth weighing against a corded alternative.

Overview
A cordless personal blender with a detachable 22-ounce vessel that twists off the rechargeable base for sipping on the go, running three preset programs for smoothies, crushing, and blending.
The base is what sets this apart from a corded personal blender: a full charge takes about 3 hours and a battery indicator shows remaining charge. The blade sits built into the vessel itself, so pre-blended drinks can go straight into the fridge without staying attached to the motor.
- 22 oz detachable Twist & Go vessel
- 3 Auto IQ programs: smoothie, crush, blend
- Rechargeable base, about 3 hours to full charge
- Lid and vessel are top-rack dishwasher safe
Who it's for
People who want to blend a smoothie or shake away from an outlet, whether that is a gym bag, a car, or a campsite, and who are fine with a single-serving 22-ounce capacity. Not for anyone blending large batches or needing continuous runtime without recharging.
Pros and cons
- Battery needs recharging every few days with regular use
- Plastic vessel can be harder to keep clean than glass
- At least one report of the unit overheating after weeks of use

Frequently asked questions
How long does the Ninja Blast Max battery last on a charge?
Ninja rates a full charge at about 3 hours, and several owners report the battery itself needs a recharge every couple of days with regular daily use.
Can the Ninja Blast Max vessel go in the fridge?
Yes, because the blade is built into the 22-ounce vessel rather than the base, it can detach and be stored or carried separately.
Is the Ninja Blast Max dishwasher safe?
The lid and vessel are top-rack dishwasher safe; the motor base should not be submerged.
