Electric vacuum machine
How It Works】Electric Mason Jar Sealer works by using the difference in air pressure to seal the lid. The machine takes out some air from the jar, making it feel like an invisible hand is pressing on the lid. So, please do not seal things that make gas easily, like cola—it can only stay sealed for a few minutes. But for things like water that don't make gas, you can seal them for a long time.【Free Up Your Hands】The machine will automatically stop after 30s of countdown work.Make sure you get it set on the lid properly (don't use the ring) then simply push the button and the unit counts down from 30 seconds for the seal. You can add or subtract time, we recommend 30 seconds. You no longer need to press the manual vacuum pump with both hands ten or twenty times.【plain to carry and place】 This rechargeable portable vacuum sealer is so convenient! No more digging out the big corded bag sealer and fighting with attachments, and it gives a better, and much easier, seal. Its compact size fit
