This is the compact device that reduces the amount of space your clothing takes up in a closet or suitcase. Simply place your clothes into the included zipper storage bag and attach the vacuum travel compressor to the built-in valve. It expels air from inside the bag, shrinking the size of the bag and any clothing, towels, or other soft essentials by up to 50% in less than five minutes. A smart sensor on the device automatically shuts the compressor off when all air has been removed. Ideal for storing off-season clothes or condensing articles when traveling, the compressor is about the size of a D-battery and easily fits into a drawer or backpack. USB plug.
