Is the Mason Genie worth it?

If you already store food in mason jars, it is a cheap way to extend shelf life without a full vacuum-sealer machine. At $56.33 at Amazon as of November 5, 2026, it costs less than most countertop sealers.

Which jars and lids does it work with?

It fits regular- and wide-mouth mason jars, including Ball, Kerr and store brands, and the included lid adaptor lets it use store-bought lids. Some buyers found certain store-brand jars needed a second try.

How long does the battery last?

Mason Genie says a full USB-C charge is good for roughly 200 seals. A few buyers reported occasional error codes while charging.

How long does sealing take?

The listed sealing time is under 40 seconds, and the brand says one press removes about 99% of the air in 30 to 60 seconds.

What comes in the box?

The kit includes the sealer, a lid adaptor, five regular-mouth and five wide-mouth chalkboard-top lids, a USB charger and a keychain lid opener.

Does it work for liquids like guacamole?

It seals jars of liquids, but some buyers found guacamole still browned a little. It suits dry goods and fresh produce best.
