Automatic Electric Wine Cork Vacuum Cleaner - Convenient Reusable Wine Saver, 7 Days Freshness Preserver, 2 AAA Batteries (not included)

Superb build quality - An absolute friend to bartenders, our electronic wine saver vacuum pump is made from durable food-grade silicone on the inside and food-grade ABS on the outside. This makes each of our wine bottle stoppers non-toxic and safe to use. It also allows you to enjoy an open bottle of wine much longer without compromising its flavor.

Keeps your wine fresh - Once applied, our wine pourer and stopper becomes airtight and prevents oxidation by sucking the air out of the bottle. Our wine saver vacuum pump will help preserve the flavor of an open bottle of wine for weeks instead of just a few days. Our wine stoppers are a practical and functional solution for any home, bar, or restaurant.

Our electronic wine caps can accommodate bottles with an outer diameter of 29 mm ± 0.5 mm and an inner diameter of 20 mm ± 0.5 mm. Absolutely no leaks or spills – once attached to the bottle's neck, our electronic wine cap suction mechanism automatically creates an airtight seal and checks the air pressure inside the bottle. If the negative air pressure drops below -0.01 MPa, our intelligent wine preservation system automatically performs repeated pumping to ensure a constant suction level. Using our wine stopper ensures the contents inside stay fresh and also prevents leaks if the bottle isn't stored properly. Super easy to use – all you have to do is press one of our rubber wine stoppers into the bottle's opening. A blue digital breathing light will then appear to indicate a vacuum seal. Once the bottle is tilted at a 45-degree angle, our wine pump's anti-drop function activates and a red light flashes, allowing you to pour the contents. The vacuum sensor in the wine bottle stopper will then automatically reactivate once the bottle's angle is again less than 45 degrees. Like I said, super easy!
