Not every “canner” can actually can.
We list 7 stovetop pressure canners by how many quart jars one load holds, from 20 down to 4, with the gauge type and warranty for each. All 7 are in the stovetop equipment class USDA processes were written for. Electric multi-cookers with canning buttons are excluded and explained: NCHFP is on record. We show no prices and rank nothing by price. We publish no process times and no safety advice — we index the record.
What we measure
Four facts per canner, each from the maker’s page or NCHFP: jar capacity, equipment class, gauge type and warranty.
How many quart and pint jars one load holds, per the maker’s spec. The table is listed by quart jars, most first; a 16-quart and a 23-quart both hold 7 quart jars, and the bigger pot fits more pints.
Whether it’s the stovetop equipment class USDA processes were developed on — per NCHFP’s guidance. Electric multi-cookers are not.
Dial gauges need an annual accuracy check (your extension office does it); weighted gauges don’t — but give no readout. Some canners carry both.
From Presto’s 12-year to All American’s lifetime, as each maker states it.

Jars per load = the quart and pint jars one load holds, from each maker’s spec or retail listing; each canner’s page names the source and the read date. The table is listed by quart jars, most first, then by pint jars, then by name. It is an order, not a ranking, and no price enters it. Capacity is the pot’s liquid volume in quarts. USDA class means a stovetop pressure canner in the equipment class NCHFP’s guidance describes — the USDA and NCHFP publish guidance, not equipment approvals, and neither certifies canners. Dial gauges need annual accuracy checks; weighted gauges don’t. We publish no process times and no safety advice — for tested recipes use NCHFP, the USDA Complete Guide, or your extension office. Each row’s sources and read dates are in the dataset. Some product links are affiliate links — if you buy through them we may earn a commission, at no cost to you. As an Amazon Associate we earn from qualifying purchases. Links appear only on canners in the USDA equipment class — never on the excluded rows — and they never change the order.
Sold for canning — but the authorities never validated them
Electric multi-cookers and digital canners are marketed with canning buttons and even “meets USDA guidelines” claims. NCHFP is on record that USDA pressure processes were not developed for electric multi-cooker appliances, and no authority has validated one. They are kept out of the table entirely — each card links the full sourced answer.
Why this table is different
The canning button isn’t a process
USDA process times assume a stovetop canner’s heat-up, venting and cool-down. NCHFP’s statement on electric multi-cookers is public and quotable — we quote it. The Instant Pot answer →
“Meets USDA guidelines” ≠ USDA-recommended
One electric canner claims it — on the maker’s own thermocouple testing. Real engineering, still a manufacturer claim; extensions still say stovetop. The label, decoded →
The lids are the other trap
Counterfeit “Ball” lids on Amazon fail to seal — documented since 2020 and acknowledged by Ball’s parent. A jar that doesn’t seal is spoilage waiting. How to spot them →
