Ninja Blast Portable Blender, Cordless 16oz Personal Blender for Shakes & Smoothies, Up to 15 Blends per Charge, BPA Free, Leakproof Lid, USB‑C Rechargeable, Dishwasher Safe, Black, BC100BKC

Reddit users have observed a discrepancy regarding the vessel's capacity. While the official product specifications list 16 oz (454 g) for ingredient weight, some community discussions mention an 18 oz (approximately 532 ml) liquid volume capacity. This variance likely stems from different measurement conventions—weight versus liquid volume. For practical usage, users can anticipate fitting around 16 to 18 ounces of their chosen ingredients or liquid for a single serving, ensuring it doesn't exceed the fill line.

Cleaning the Ninja Blast, particularly around the stainless steel BlastBlade Assembly and the gasket, can be a point of contention for users, especially after blending powders like protein supplements. Forums like r/Smoothies suggest that while the lid and vessel are dishwasher-safe and a 30-second self-clean cycle is available, manual scrubbing may be necessary to remove fine residue or prevent gunk buildup under the gasket for optimal hygiene.

While user descriptions on r/KitchenStack characterize the Ninja Blast's noise as a 'buzz' rather than a 'jet engine' and quieter than full-size Ninja blenders, a specific decibel (dB) rating is not provided. Portable blenders typically operate between 70-90 dB. For context, a normal conversation is around 60 dB, and a vacuum cleaner can be 70-80 dB. The 7.4-volt motor and blade design likely contribute to its moderate noise profile, making it suitable for early morning use without excessive disturbance.
