Our take
The NJ1004 is best understood as a stackable set of four small chopper bowls sharing one power head. Ninja's guide states 16 ounces or 2 cups per bowl and lists four bowls, not one 8-cup work bowl. That distinction makes it a compact, small-portion option with a useful storage arrangement. Its manual supports chopping and pureeing with a four-blade assembly, while leaving disc cutting, dough preparation, and specialty kits outside the documented package.
For small chopped or pureed preparations where multiple separate 2-cup containers are more useful than one larger bowl..
It is not suitable for a single medium or family-size batch, a full-size slicing/shredding workflow, dough mixing, or anyone who needs one large bowl rather than several separate small containers.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The guide identifies four separate bowls, each with a 16-ounce or 2-cup capacity.
- A one-touch pulse button and four-blade assembly are documented for chopping and pureeing.
- Splash guards double as storage lids, and the bowls stack for cabinet or refrigerator storage.
What to weigh up
- A single bowl is limited to 2 cups; the four bowls cannot be added together as an 8-cup working vessel.
- The guide lists no slicing or shredding disc, dough blade, dicing kit, or spiralizer.
- The historical renewed ASIN and exact seller package are not independently verified.

| Model covered | NJ1004 |
|---|---|

What the features mean for you
Four two-cup bowls rather than one large processor
The NJ1004 manual lists four processing bowls, each with a 16-ounce capacity, and a 200-watt power head. That makes each individual batch a two-cup job. The four containers can be stored separately and stacked, but their capacities should not be added together when deciding whether a recipe fits. Someone who prepares a small salsa or chops a limited quantity may appreciate the arrangement; someone processing one larger batch should consider a full-size bowl processor instead.

The separate containers support staged prep
The guide's parts list includes four matching bowls and four splashguard/storage lids. Because the vessels are the same size, this is not the common large-bowl-plus-mini-bowl setup. The practical distinction is having multiple small containers available for separate ingredients or storing prepared portions. The available evidence does not describe a separate bowl as a different processing stage, and the matching profile does not claim a second mini bowl. Check the seller package for all four bowls if you are shopping from a renewed listing. [smallBowl]
Pulse control and chopping blades are the documented jobs
Ninja identifies a one-touch pulse button and its four-blade assembly, and the use instructions describe chopping and pureeing. Short pulses give the user a way to stop between bursts, while the manual advises against running longer than 15 seconds at a time. These are published operating instructions rather than evidence about how evenly the chopper handles a particular ingredient. The guide does not list a reversible disc or other tool for slicing or shredding, so this is not a substitute for a processor that cuts vegetables into repeatable slices. [sliceShred]
The tool list keeps specialty expectations narrow
The manual's included parts are the power head, four bowls, four lids or splash guards, and a four-blade chopping assembly. It does not identify a dough blade, dicing grid, spiralizer, or dedicated grinder attachment. Mincing with a chopping blade should not be confused with a separate meat-grinding assembly. This limited tool set is useful for a compact chopper, but a shopper looking for bread dough or prepared vegetable cuts should compare against an appliance whose source explicitly lists those components. [doughBlade, dicingKit]
Electrical and seller identity are documented separately
The guide names NJ1004 and specifies 120 volts, 60 hertz, and 200 watts. A frozen Amazon record used a renewed title, but its ASIN was not crosswalked to a current exact Amazon offer. We therefore use a tagged exact-model search rather than claiming that historical ASIN as a live product page. Confirm that the seller's item says NJ1004 and includes the separate bowls and splashguard lids. The profile describes the manufacturer's model kit and does not promise a seller's condition, color, price, or availability. [bowlCapacityCups]
What else to compare
For one compact bowl, compare the Ninja NJ110GR; for a documented large bowl and multiple cutting tools, compare the KitchenAid KFPW760OB.
