Overview
Cordless and USB-C rechargeable, the Ninja BC151PR Blast blends an 18-ounce vessel of frozen fruit or protein powder using a stainless steel BlastBlade assembly, then doubles as the cup you drink from via its sip lid.
Being cordless and rechargeable rather than plugged into a base is the entire point here, and reviewers who use it daily for protein shakes and fruit smoothies are largely positive on that tradeoff. The recurring friction points are blade cleaning, which several owners solve with a toothbrush, and battery longevity, which a minority describe degrading or failing within months.

- USB-C rechargeable, cordless operation
- Stainless steel BlastBlade Assembly
- Separate power and blend buttons
Who it's for
Blending on the move, away from an outlet, and drinking from the same cup is exactly what this suits, for shakes and smoothies especially. Regular blending of dense mixes like whole grains or very hard ice calls for a countertop model with more torque.
What buyers say
From Amazon customer reviews.
Daily users praise the convenience of blending and drinking from the same cordless vessel, especially for protein shakes and fruit smoothies, and several note it outperforms competitor portable blenders they'd tried. The most common complaints are battery reliability, with some units losing charge quickly within months, and occasional stalling on denser ingredients that requires shaking the vessel to clear.
