This electric vacuum pump is a must-have! If you are currently using the accessory port on a large and loud electric bag sealer, you are going to love how quiet this vacuum pump is. It’s also very light - just under 7 ounces. The e-pump is rechargeable so it can go where you need it. It is designed for use with the That Seals It! Vacuum Lid. This e-pump also has a built-in automatic shut-off feature. Just firmly seat the pump into the lid recess, turn it on and walk away. Once a deep vacuum inside the container is reached it will shut off. This e-pump also works great with zippered vacuum bags. The clear vacuum chamber is removeable. Any liquid accidentally sucked out of the bag is collected in a reservoir and then the chamber can be removed and cleaned. The seal on the chamber is made with food-grade silicone. The This Sucks Big Time! e-pump is a convenience game changer!
