【For All Your Vacuum Sealing Needs】Includes an electric vacuum sealer with a wide mouth sealing clamp, a standard mouth sealing adapter, 5 wide mouth jar lids, 5 regular mouth jar lids, a charging cable, and a user manual. Our vacuum sealing kit for food helps you remove air from your jars and extend the shelf life of your stored food. 【Portable Vacuum Sealer】Don't have a vacuum sealer? Don't worry!!! We offer you an electric jar sealer that you can use to extract air from your jars. Is the sealer too big to take with you when you travel or have a picnic? You can also use this cordless jar sealer instead. 【Easy to Use】The food vacuum sealer with a standard mouth sealing adapter is suitable for wide mouth and regular mouth jars (jars not included). Make sure the electric jar sealer is centered and pressed properly against the jar lid, press the button to start the vacuum pump for 30 seconds or more, and the air can be evacuated to the seal. By pressing the button again, the sealer will shut off. 【Suitable for Two Types of Jars】The electric jar sealer includes two sizes of mouth sealing clamps for your daily use. To get the jar with a standard mouth sealing, simply insert the red arrow into the standard mouth sealing adapter, align it with the unlock symbol on the main body, and then insert it into the silicone ring in the wide mouth sealing area and turn it clockwise. At this point, the arrow is aligned with the lock symbol, indicating a successful installation. 【Note】To ensure a good seal, do not fill the jars with liquid food and make sure the lids are dry. Too much liquid will cause a small difference in air pressure between the inside and outside of the jar, resulting in an improper seal.
