The Ultimate Electric Mason Jar Vacuum Sealer
Mason jars are incredibly versatile. But without removing the air, your food won't stay fresh as long as it could. Oxygen causes spoilage, staleness, and freezer burn. The electric Mason jar vacuum sealer solves this problem. It removes air from your jars with the push of a button, creating an airtight seal that keeps food fresh much longer.
This kit works with both wide mouth and regular mouth Mason jars. The cordless, rechargeable design means you can use it anywhere in your kitchen without being tethered to an outlet. No hoses. No complicated setups. Just place the sealer on top of your jar, press the button, and watch the vacuum do its work.
Perfect for dry goods, leftovers, sous vide, fermenting, and even vacuum sealing bags with the external attachment. This is the all-in-one food preservation tool your kitchen has been missing.

Works with Wide Mouth and Regular Mouth Mason Jars
The biggest challenge with jar sealers is compatibility. Many only work with one jar size. This electric Mason jar vacuum sealer is designed to work with both.
Wide Mouth Jars: The sealer comes with a wide mouth attachment that fits securely over standard wide mouth Mason jars. These are the jars typically used for canning larger items like whole fruits, vegetables, and larger batches.
Regular Mouth Jars: For standard size Mason jars, simply attach the included regular mouth converter. The converter inserts into the wide mouth seal, allowing you to seamlessly switch between jar sizes.
No Hoses Required: Unlike traditional vacuum sealers that require accessory hoses and separate attachments, this electric sealer sits directly on top of your jar. No complicated setup. No lost parts.
Cordless and Rechargeable – Freedom to Seal Anywhere
Traditional vacuum sealers tether you to an outlet. They require counter space and a nearby power source. This electric Mason jar vacuum sealer is completely cordless.
Rechargeable Battery: The built-in 2000mAh battery provides enough power for approximately 300 seals on a full charge. That's months of use for most home cooks.
USB Charging: Recharge with the included USB-C cable. Charge from your laptop, wall adapter, power bank, or car charger.
Use Anywhere: Take it to the pantry to seal jars of dry goods. Use it at the dining table for leftovers. Bring it to the farmers market to seal fresh produce. No cords, no limitations.
Travel Ready: The compact size and cordless design make it perfect for RVs, cabins, or vacation homes.
One-Button Operation – Incredibly Easy to Use
You don't need to be a food preservation expert to use this Mason jar vacuum sealer.
How It Works:
- Fill your Mason jar with food, leaving about 1 inch of headspace at the top.
- Place a standard Mason jar lid on the jar (the same lids you already use for canning).
- Place the electric sealer on top of the jar, centering it over the lid.
- Press the button once.
- The sealer automatically removes air and stops when the vacuum is complete.
- Remove the sealer. Your jar is now vacuum sealed.
No Monitoring Required: The automatic shut-off feature means you don't have to watch the clock or guess when to stop. The sealer senses when the vacuum is complete and turns off automatically.
Seal Only Mode: Some models also include a seal-only function for resealing bags and other applications.
Preserves Food Freshness
Why does vacuum sealing work? Because oxygen is the enemy of fresh food.
How It Works: Removing air from the jar eliminates oxygen. Without oxygen, the chemical reactions that cause spoilage slow dramatically. Mold, bacteria, and yeast also need oxygen to thrive.
Extended Shelf Life: Vacuum sealed foods can last 3 to 5 times longer than traditional storage methods.

No Freezer Burn: When freezing food in jars, vacuum sealing prevents freezer burn by eliminating the air that causes moisture loss.
Perfect for Canning and Fermenting
This electric sealer is a game changer for home canners and fermenters.
Fermentation: When fermenting vegetables like sauerkraut, kimchi, or pickles, vacuum sealing helps create the anaerobic environment needed for beneficial bacteria to thrive. The automatic vacuum removal ensures a consistent environment batch after batch.
Dry Canning: Vacuum sealing is perfect for dry goods like rice, beans, pasta, oats, and flour. Remove the air, seal the jar, and store in your pantry without worrying about pests or staleness.
Sous Vide: While not all electric jar sealers include this feature, many upgraded models can also vacuum seal sous vide bags using an external attachment. Check your specific model for compatibility.

Preserve Leftovers: That half jar of pasta sauce? Vacuum seal it. Leftover soup? Vacuum seal it in a jar. Cut herbs? Vacuum seal them.
Seasonal Produce: When berries are on sale, buy extra. Vacuum seal them in jars and refrigerate. They'll last weeks instead of days.
How to Use – Step by Step Guide
Step 1: Prepare Your Jar
Fill your Mason jar with food. Leave about 1 inch of headspace at the top. This space allows the vacuum to form properly.
Step 2: Add the Lid
Place a standard Mason jar lid on the jar. You can use regular canning lids – the same ones you already have.
Step 3: Position the Sealer
Place the electric sealer on top of the jar. Center it over the lid. For regular mouth jars, attach the converter adapter first.
Step 4: Press the Button
Press the power button once. The sealer will start automatically.
Step 5: Wait for Completion
The sealer runs for about 30-50 seconds, depending on the jar size and contents. It will stop automatically when the vacuum is complete.
Step 6: Remove and Serve
Lift the sealer off the jar. The lid should be depressed, indicating a successful vacuum seal. Store or serve as desired.
Pro Tip: For the best seal, ensure the rim of the jar is clean and dry before placing the lid. Any food residue can prevent a proper seal.
