How many jars does it hold?

The canner has a 23-quart liquid capacity and a 17-quart canning capacity. The rack holds standard pint and quart jars in a single layer, so expect roughly 7 quarts or more pints per batch.

Does it work on a glass-top stove?

It is electric and plugs into a 120-volt outlet, so it does not sit on the stove at all. That makes it usable with any cooktop, including glass-top and induction.

Do I still need to adjust for altitude?

Yes. Pressure canning still depends on altitude, and the presets and manual let you set the right pressure for your elevation.

Is it worth it over a stovetop canner?

If you want guided presets, a digital readout and a free stove, yes. If you can only do a few batches a year and want to spend less, a stovetop pressure canner costs far less.

When is the best time to buy?

The best new price is $368.79 at Amazon as of November 5, 2026, near the top of its recent range. Canning gear tends to dip in late winter and early spring, before harvest season.
