Ninja Blast Portable Blender Review: Would Owners Buy It Again?

How this review was made: We did not test this blender in person. This verdict is based on our analysis of expert reviews and owner themes, all listed at the end of this article. We looked hard for a pattern of failures; we found one report of it, but not enough to call it a skip. Our method.
Good at smoothies, but battery reliability is the open question
Testers found the Ninja Blast quiet, easy to clean and good at fruit smoothies and protein shakes, with a charge that covered roughly seven to twelve 30-second blends. Against that, one review aggregator reports that many units fail within days with charging and battery faults, and testers say ice and fibrous greens can jam the blades. The positive hands-on tests outweigh a single negative summary, so we call it a qualified yes for light smoothie use rather than a skip.
Check current price on Amazon → Prices and availability change often, so we don't list them here.Buy it again if you…
- make single-serve smoothies and shakes away from home
- want a quiet blender that doubles as a drinking cup
- mostly blend soft fruit, yogurt and powders
Skip it if you…
- crush a lot of ice or tough leafy greens
- need a blender that runs for many cycles per charge
- want to blend hot ingredients or thick nut butters
The Ninja Blast (model BC151) is a rechargeable personal blender with an 18 oz vessel, a flip-open drinking lid and a USB-C charging port. A 30-second blend cycle starts with one press.
We combed hands-on tests and owner themes. Hands-on tests are positive, but battery complaints appear in at least one aggregator, so we note where evidence is thin.

What owners complain about
How it holds up over time
We found no rigorous long-term test. The positive tests were short, and the one negative summary talks about early failures without giving numbers. If you buy one, charge it fully, test it early and keep the return window in mind.
Tips from testers
- Layer it right: liquid first up to the line, then fruit and powders, with frozen items or ice last.
- Use small or thin ice with enough water, not a cup of cubes alone.
- Skip very thick mixes such as nut butter, which can block the blades.
- Do not add hot ingredients; the manual warns against it.
