1、Compared to the traditional wine vacuum pump that you need to manually press repeatedly to extract the vacuum inside the red wine bottle, our electric wine stopper only needs to be pressed into place while the blue evacuation indicator lights up. You can automatically evacuate the whole process, and just wait quietly for the evacuation indicator light to go out to easily keep the freshness of wine as ever. 2、The wine vacuum stopper will constantly and automatically detect the air pressure inside the bottle. When the bottle load pressure leakage exceeds ‑0.01MPa, the electric wine stopper will start again to exclude the air inside the bottle and keep the vacuum inside the bottle, so as to achieve a good preservation effect. 3、When the Wine Vacuum Pump is in working condition and the bottle is tilted to 45 °, it will trigger the anti‑pour‑out function, the red wine vacuum pump will automatically stop pumping vacuum and light up a red light to remind you. This prevents the bottle from tilting and continuing to pump air and causing the wine to flows back inside the soft red wine stopper causing a malfunction. When the bottle returns below 45 degrees, the wine stopper will work again. 4、The preservation effect of this electric wine stopper is more than that of other ordinary stoppers, so that you can enjoy each bottle, down to the last drop, which is suitable for all red and white wine. This stylish and functional stopper is a perfect gift for your favorite parents, your dear, your friends or yourself, and it is also the best gift for red wine lovers. 5、Whether youre starting a collection for your home or gifting your friend as souvenirs, these are all a good choice. It is suitable for birthdays, advertising promotions, anniversary celebration, festival, awards ceremony, wedding, business gifts, household items.
