Overview
This is an Amazon Renewed unit of Ninja's Blast cordless personal blender, an 18 oz USB-C rechargeable blender with a sip lid, built for shakes and smoothies away from an outlet.
Being cordless is the whole appeal here: the 7.4V base charges via USB-C and then blends without being plugged in, which several reviewers use specifically for the gym or their teenager's protein shakes. Separate power and blend buttons keep it from starting by accident. Because the motor base doesn't detach from the vessel, charging and drinking share the same footprint, unlike a wired blender with a removable jar.
- 18 oz BPA-free blending vessel
- Sip lid with hinged carry handle
- Self-clean cycle with water and dish soap
- USB-C rechargeable 7.4V base
Who it's for
Suits anyone who wants a cordless personal blender for shakes on the go and is comfortable buying a Renewed, previously used unit. Not for buyers who want a wired blender with a base that fully separates from the cup.
What buyers say
From Amazon customer reviews.
Owners say it handles ice and frozen fruit well for its size, holds a charge across multiple blends, and is easy to carry to the gym, work or on the go. The main criticism is that the motor base stays attached to the vessel rather than detaching the way a wired blender's jar does, and one buyer specifically wanted a plug-in model instead of a rechargeable one.
Strengths and trade-offs
Drawn from this product's published specifications.
- Cordless USB-C rechargeable base needs no nearby outlet
- Separate power and blend buttons prevent accidental starts
- 18 oz vessel doubles as a sip lid cup
- Motor base doesn't detach from the vessel
- Renewed unit, not new factory packaging or full warranty
- Not ideal for very hard ice cubes
Performance notes
The stainless steel BlastBlade assembly works with the vessel's ribbed interior to create a vortex that pulls frozen fruit and ice into the blades. A 30 second self-clean cycle with water and a drop of dish soap handles most cleanup, and remaining parts are dishwasher safe.

Questions about the Amazon Renewed BC151
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Is the Ninja BC151BK Blast blender new or used?
This listing is an Amazon Renewed unit, meaning it's a professionally inspected, previously used blender rather than new factory stock.
Does the Ninja Blast portable blender need to be plugged in while blending?
No, it runs on a 7.4V rechargeable base charged via USB-C, so it blends cordlessly once charged.
Can the motor base be removed from the blending vessel?
No, reviewers note the base stays attached to the vessel, so charging and drinking share the same footprint.
