The catch
Zojirushi Induction NW-QAC10BA
Food height in the smaller steam tray is limited to 1.5 inches, and brown rice tops out at four dry cups.
Side by side
Zojirushi NW-QAC10 vs NW-QAC18: QAC18 makes batches larger but gives up one-cup quinoa and brown-rice lunches
Quick verdict
Go with the NW-QAC10 for half-cup white rice or steel-cut oats and one-cup quinoa or brown rice. Take the NW-QAC18 for larger batches or taller food, up to its steam-tray limit. Because the larger cooker starts at two cups for quinoa and brown rice, it can be a poor fit for small fresh lunches.
Before you buy
Why, and what it costs you
A small breakfast may count for more than a big dinner
Suppose one person makes half a measuring cup of steel-cut oats before work and later cooks one cup of quinoa. QAC10 handles both jobs, while QAC18 starts at one cup of oats and two cups of quinoa. Buying for the occasional large dinner would mean changing two regular meals and not just gaining spare room.
Where this comes from
This assumes those are the dry quantities you use. The manufacturer’s supplied cup holds about 180 mL, and no serving count is inferred.
The catch
Zojirushi Induction NW-QAC18BA
A two-cup minimum on brown rice and quinoa can leave you with leftovers you didn’t want.
Zojirushi Induction NW-QAC10BA
- Why pick it
- The same cooker has to turn out a small breakfast and a one-cup grain lunch.
- You’d like the shallower body and rarely go beyond four dry cups of brown rice.
- The catch
- Food height in the smaller steam tray is limited to 1.5 inches, and brown rice tops out at four dry cups.
Zojirushi Induction NW-QAC18BA
- Why pick it
- Batches of brown rice or quinoa above four cups are routine for you.
- The food for a separate steam cycle is taller than 1.5 inches on the tray, but stays within the 2.75-inch limit.
- The catch
- A two-cup minimum on brown rice and quinoa can leave you with leftovers you didn’t want.

What this page compares
Size your QAC by breakfast oats, brown-rice batches, how tall the food on the steam tray can be and where the cooker will be stored. The limits come from the US manual.
Both QAC sizes have the same grain programs. Minimum batches and steam-tray limits decide which one suits a household whose meals change through the week.

In practice
Differences you will notice
A small breakfast may count for more than a big dinner
Suppose one person makes half a measuring cup of steel-cut oats before work and later cooks one cup of quinoa. QAC10 handles both jobs, while QAC18 starts at one cup of oats and two cups of quinoa. Buying for the occasional large dinner would mean changing two regular meals and not just gaining spare room.
How we worked this out
This assumes those are the dry quantities you use. The manufacturer’s supplied cup holds about 180 mL, and no serving count is inferred.
A larger steam tray adds height and does not give you two dishes at once
In its steam tray, QAC18 takes food up to 2.75 inches high, against 1.5 inches in QAC10. That can help with a thicker item that fits the tray and a suitable steaming recipe. It doesn’t show that rice can cook underneath at the same time. Treat rice and steaming as separate jobs unless the supplied instructions specifically cover the combination.
How we worked this out
The height limits are taken from the US specification table. The steam instructions have you fill the pan with water. No tray volume or simultaneous rice capacity is inferred.
Cooking more grain takes a deeper permanent spot
Compared with QAC10, QAC18 is 1.125 inches wider and 1.125 inches deeper. On a shared counter, measure what space remains for a chopping board and other appliances before you pick the larger grain range. If the cooker is stored between uses, also check the shelf load and opening, and don’t rely on its nine-inch closed height.
How we worked this out
The manufacturer body sizes are 9.25 × 12.25 × 7.875 and 10.375 × 13.375 × 9 inches. Lid-opening and steam clearance are not included.

Spec by spec
Where they really differ
| Spec | Zojirushi Induction NW-QAC10BA | Zojirushi Induction NW-QAC18BA | In practice |
|---|---|---|---|
| Brown rice | 1 to 4 dry cups | 2 to 8 dry cups | Short and medium-grain brown rice is what these ranges cover. |
| Quinoa | 1 to 4 dry cups | 2 to 6 dry cups | More rice capacity doesn’t translate into ten cups of quinoa. |
| Steel-cut oats | 0.5 to 2.5 dry cups | 1 to 3 dry cups | A small breakfast may be reason enough to stay with the smaller cooker. |
| Steam food-height limit | 1.5 inches | 2.75 inches | Water goes in the pot in the steam instructions, so this isn’t a simultaneous rice-and-side capacity. |
Trade-offs
What each pick costs you
With Zojirushi Induction NW-QAC10BA
- You still have to wash the removable parts after a cleaning cycle runs.
With Zojirushi Induction NW-QAC18BA
- Running the cleaning cycle doesn’t take the place of washing the pot and removable lid.
Change of plan
When the answer changes
Your regular batch is one cup of brown rice or quinoa
Go with Zojirushi Induction NW-QAC10BA. That amount works on QAC10, while QAC18 starts at two.
Your recurring quinoa batch runs five or six cups
Go with Zojirushi Induction NW-QAC18BA. QAC18 handles that quantity, though you still need to check room and cleanup.
