FreshLock Pro removes oxygen to slow staleness and spoilage — it is not a pressure canner and cannot sterilize food for wet canning. It excels with coffee, herbs, grains, and refrigerated leftovers.

Yes. FreshLock Pro is designed for all standard and wide-mouth mason jars, including popular brands like Ball and Kerr. If it has a flat lid, it almost certainly works.

Each seal uses just 2-3% of the battery, so a full charge typically powers 60 to 100 sealing cycles depending on jar size. The 30-day standby rating means it stays ready in your drawer without constant recharging — just grab it when you need it.

FreshLock Pro works well on most fridge items — avocados, sauces, and cut vegetables stay fresher noticeably longer. Avoid sealing hot liquids or carbonated drinks; it is not designed for wet canning.

The device stops on its own once optimal vacuum is reached — you'll feel and hear it click off. The digital display also shows elapsed time and remaining battery so you're always in the loop.

Coffee and herbs that go stale in weeks stay fresh for two to three months when vacuum-sealed. Dry grains that last six to twelve months can hold for two to five years stored cool and dark with FreshLock Pro.

Absolutely. All 10 included caps are built for repeated use. Rinse them with warm soapy water, let them dry fully, and they'll maintain a reliable seal cycle after cycle.

Oxygen absorbers are one-time use and need replacing every time you open a jar. FreshLock Pro removes up to 83% of oxygen with a reusable valve lid, which handles everyday pantry and fridge storage on its own.
