NESCO NPC-9 Smart Canner: A Cooker and Canner in One

It costs less than the plug-in canners made just for canning, and it also makes dinner. Here is what is documented, with no verdict of our own. The full comparison of what the sources say about electric canners is on its own page.

What is the NPC-9?

NESCO is a registered trademark of The Metal Ware Corporation, per the guide. The NPC-9 is sold as the 9.5 Qt. Digital Smart Canner & Cooker. "Smart canner" is a product name, not a type of machine. On our guide to electric canner types it counts as a cooker and canner in one. It pressure cooks, slow cooks, steams and browns, and it also has water bath and pressure canning modes.

That sets it apart from the Presto Precise. Presto sells that one for canning only, and a temperature sensor runs it. The NPC-9 uses pressure regulators, also called jigglers. What's said about one doesn't carry over to the other. NESCO vs. Presto goes through the differences.

What does NESCO say about it?

Everything in this table is NESCO's own statement, from its Care/Use Guide and product page. None of it is a safety finding.

PSI is how pressure is measured. This site has no altitude table. The altitude page explains who does what, machine by machine. The National Center says the same pressure and time can't be used at all altitudes.

What do the experts say?

Who names it. We found no statement from the National Center or any government source naming NESCO or Carey. So saying the National Center calls this machine unsafe goes further than it has. Calling it safe skips what is missing.

What reaches it by type. Penn State's wording on combination appliances is above. NESCO's guide tells you to use the USDA Complete Guide for tested recipes and follow its instructions exactly. The National Center says its advice was written for stovetop pressure canners that hold four or more quart jars upright. It does not support USDA canning instructions in electric multi-cookers. The National Center hasn't said whether the NPC-9 counts as a multi-cooker. It does have the functions of one.

Why the jar count isn't the whole story. The National Center says the research behind the USDA's low-acid pressure instructions was done in canners most like today's 16-quart or larger models. It says the heating up and cooling down count toward the process. Holding four quart jars is only one of several conditions. It doesn't prove the heating, holding and cooling match the tested instructions. The temperature decides.

What isn't evidence here. A Utah State study covered three unnamed electric cookers. It names no model, so it isn't a test of this machine.

Which two passages in the guide should I read slowly?

The wording of the guide's canning sections can trip you up:

• The low pressure section says it is for high-acid foods (jam, most fruit, pickles) and names most fruits and sauces. The August 2025 guide's same section also named most vegetables and soup stocks, so check which version you have. The USDA counts all fresh vegetables except most tomatoes as low-acid.
• The section headed high pressure canning, which NESCO says is for low-acid vegetables, meats, soups and stews, opens with the words "low pressure canning."

If either passage leaves you unsure, ask NESCO customer service before you can, at 1-800-288-4545 per the guide. Ask your state's university extension office (free local food-safety advice) too. We won't guess for you.

What does one owner report?

Creative Canning is an affiliate blog. Its author writes that she owns a Nesco/Carey model and finds it much less automatic than the Presto. She says she once started the timer before the machine reached pressure and had to reprocess the jars. She doesn't recommend it because of that room for human error. That is one person's account, not a measurement, and we haven't checked it.

Who might it suit, and what do we suggest instead?

If you mainly want a pressure cooker and slow cooker, and would water bath the odd batch of pints, the NPC-9 is the machine to read about, with its warning in mind. It is mid-range in price.

Type

Combination cooker-canner with regulator weights

Pressure canning

Yes, by NESCO's statement only

Water bath

Pints and smaller only, per NESCO

Steam

NESCO's guide has a low-pressure/steam section; this is not what the Wisconsin and NCHFP steam-canner research covered

Liquid capacity

9.5 quarts

Jars per load

4 wide-mouth quarts, or up to 5 pints; dry-fit first

Altitude

Black regulator up to 1,000 feet, green regulator above; not above 7,500 feet, per NESCO

Price class

Mid-range

Stated in: NESCO NPC-9 Care/Use Guide (revision of October 27, 2026), read 2 November 2026

Why here: This is the machine this page is about. It is not a pick for low-acid canning.

Best for: You mainly want a cooker and have read the caution. Not a pick for canning low-acid foods (vegetables, meat, chicken, fish).

• Also pressure cooks, steams and slow cooks, says NESCO
• Lower price class than the plug-in canners made just for canning
• Two regulators for two altitude ranges, says NESCO

• Penn State Extension says it cannot recommend this kind of appliance, because the research is missing
• Four wide-mouth quart jars at most. NESCO asks you to dry-fit jars first
• No quart jars in water bath, says NESCO
• NESCO advises against use above 7,500 feet

Read this first

This is a combination cooker-canner. Penn State Extension (September 13, 2024) says combination canner/cooker appliances cannot be recommended because the research on their safety is missing. Penn State names no brand; placing the NPC-9 in that group is our reading. NESCO's guide sends users to USDA's tables, and NCHFP (February 1, 2019) says it does not support USDA canning processes in electric multi-cookers. We found no agency statement that names this machine.

If your goal is low-acid foods (vegetables, meat, chicken, fish) on the shelf, we suggest a stovetop canner in the same price range. It is the type the National Center wrote its advice for, and Presto says it holds 7 quart jars. The open question about combination machines doesn't apply to it. You do more watching yourself. The electric vs. stovetop comparison shows that trade-off. Our stovetop canner guide covers other sizes.

Presto

Presto 23-Quart Stovetop (01781)

A pot for your stove, the kind the USDA's canning steps were written for.

Yes

Water bath

Yes, quarts and smaller, per Presto

Jars per load

7 quarts, or 20 regular-mouth pints stacked

Altitude

You raise the pressure by altitude from the USDA tables. Water bath times also change with altitude.

Price class

Mid-range

Stated in: Presto Canner Comparison Guide (2025), read 2 November 2026

Why here: It is in the same mid-range price class as the NPC-9, and it is the type the National Center says its advice was written for.

Best for: You want to pressure can low-acid foods (vegetables, meat, chicken, fish) and can stay near the stove.

• The National Center's advice was written for stovetop canners
• Seven quart jars, or up to 20 regular-mouth pints stacked, says Presto
• Also works as a water bath canner for quarts and smaller, says Presto
• Works on gas and on electric coil and smooth-top ranges, says Presto

• You watch the gauge and adjust the heat yourself
• The dial gauge needs an accuracy test every year, says Presto
• Presto does not list induction for this pot. The 01784 is its induction version

What about the Carey DPC-9SS?

The DPC-9SS guide on NESCO's site calls Carey a registered trademark of The Metal Ware Corp, the parent company of NESCO. It gives the same size, jar counts and regulators as the NPC-9 guide. Neither guide says the two machines are identical. Only retailers claim that, so it stays unconfirmed. Our Carey page sets the two guides side by side. Carey has no listing in our Amazon data, so we don't link it, and nothing above is a statement about it.

What about parts, warranty and support?

The guide lists a removable silicone gasket, two racks and both regulators. For replacements and warranty claims, ask NESCO customer service. If you own an NPC-9, keep your guide close. Our manuals page helps you check you have the right version. The overview of canning machines shows your other options.
