Presto 12 Quart Digital Pressure Canner (02144): What to Know

Small batches are a good way to learn. A small machine on the counter can feel far less daunting than a big pot on the stove. Here is what this one offers, and where it stops.

Is the 12-quart Presto right for me?

It's the one to look at if you can in small amounts, don't need water bath quarts, and want the steps automated. It isn't our first suggestion for low-acid foods (vegetables, meat, chicken, fish). That remains a stovetop canner. Among the Presto Precise family, our pick is the 23-quart, for its jar count. Our Presto Precise overview covers the whole family.

What are its pros and cons?

What are the specs?

All from Presto: the current manual, the product page and the spec sheet.

Presto says capacity may vary by jar style, and you shouldn't force jars to fit. The other sizes are on our electric canner size chart.

One difference to check. Presto's 2022 manual for this model listed 4 wide-mouth quarts. The 2024 manual and the 2025 FAQ list 5. If your booklet says otherwise, go by the manual for your unit and ask Presto.

What is it like to use?

• Where it goes. The manual says countertop only, away from the edge and away from overhanging cabinets, because of steam. The 2024 manual also asks for a heat-resistant layer, such as a large cutting board, underneath.
• Weight. Fully loaded, it can weigh more than 42 pounds, per the manual. You add jars and water where it stands, and you don't carry it full.
• Power. Use a 120-volt outlet. If you need an extension cord, Presto's manual sets a minimum rating and a maximum length.
• Care. Keep the pot dry on the outside before it goes back in. Never put the canner body in water. Presto says the sealing ring and gaskets need regular replacing.
• Faults. It shows a code when something goes wrong. Our Presto error codes page helps you find the entry.
• Altitude. Presto says no adjustment is needed when pressure canning, because the sensor holds the temperature. Nobody outside the company has confirmed that. Water bath canning always needs an altitude adjustment. See canning at altitude.

What do the experts say about this model?

Kansas State links to this model's manual. Penn State describes its jar count. Ask Extension was asked about it by name. North Dakota State speaks of the Presto Precise in general.

• Kansas State, sharing the National Center's advice, says the University of Georgia has not verified Presto's marketing statements, and that you have to trust the maker. It calls Presto's minimum temperature target a positive sign. At the time, the manual left out at least two special USDA instructions. Presto has revised the manual since, and we haven't checked whether that gap remains.
• Penn State says the digital model automates steps and adjusts for altitude. It notes that it holds fewer jars: 5 quarts or 8 pints.
• North Dakota State treats the Presto Precise as a usable option. It says to follow its instructions and use tested recipes from sources such as the National Center or your state's university extension office (free local food-safety advice).
• Ask Extension, a free question service where university experts reply, gave one reply to a reader asking about this exact model. It says the research isn't yet there to recommend electric canners for low-acid foods. This is one expert's answer, not a school's position.

We add no verdict of our own. The full comparison of positions has more.

What are the alternatives?

• Same family, taller: the 17-quart digital holds the same 5 quart jars under pressure. Presto says it adds water bath quarts.
• Stovetop: the Presto 01781 holds 7 quart jars by Presto's chart. It's mid-range in price and asks you to watch a gauge. See the Presto 01781 on Amazon^* (paid link).
• Still weighing it up? Electric vs. stovetop walks through the trade-off without a sales pitch.
