Material: Polyurethane (PU) Color: 2PC+Pump Product Dimensions: 27.6L x 21.6W x 1H Special Feature: Wireless Electric Pump, Double-Layer Fabric, Transparent, Exhaust Hole, Scratch-resistant, Sealing Zipper This travel vacuum bag measures 27.6 x 21.6 inches (uncompressed and laid flat) and weighs 0.52 pounds. It can store 45L of space. The wireless electric pump measures 3.3x2.3x2.3 inches and weighs 0.25 pounds. It is small, easy to carry, and does not take up space. It effectively compresses the soft down fabric to reduce the volume by more than 80%. The travel vacuum bags have a more excellent vacuum compression capability. Wireless Electric Pump: Double-click to turn on, single-click to turn off. 1200 mAh battery capacity, please fully charge before first use (3 hours). After fully charged, it can be used about 20 times. The red indicator light indicates that it is not fully charged, and the blue light indicates that it is fully charged. The charging port is under the sticker, and the air pump is used after the sticker is removed. Care Tips: Do not fill the vacuum storage bags too full, otherwise the zipper will be difficult to seal. Try to reduce the number of times the vacuum bag is machine washed to prevent the surface waterproof protective layer from falling off and being damaged due to multiple machine washing. Just wipe it. Zipper Tips: It is equipped with a sealing zipper similar to that on a diving suit, which is more difficult to pull than an ordinary zipper. Please pull the zipper completely to 100% of the top of the sealing mouth to achieve the best sealing effect, otherwise it will leak. If there is still leakage after pulling it to the top, repeatedly pull the zipper up and down more than 5 times to effectively reduce the zipper gap and restore the sealing state. Multifunctional Design: Equipped with a transparent viewing window to avoid the trouble of disassembling and confirming the items. The design of the waist exhaust hole allows more effective and uniform exhaust at the four corners to avoid the farthest gap from being unable to dry the air. The hand-held design makes it easy to carry and hang for washing and care. Double-Layer Fabric: Uses advanced 40DTPU and IP67 waterproof double-layer fabric, which has more excellent vacuum resistance and wear resistance. The outer nylon fabric adopts the most compact 300×300 woven process. The inner layer adopts 40TPU grade coating film. Each fabric connection is three-layer stitched. Under the premise of ensuring the product function, the modern geometric Crosshatch style X-shaped texture is designed. Tips for the Air Pump: Do not use it for more than 5 minutes each time, and let it cool down for 5 minutes before using it again. The charging voltage must not exceed 5V. The mini pump has limited suction power. If you want the ultimate vacuum effect, it is recommended to use a vacuum cleaner for better results. Do not place sharp objects together for compression. Upgraded Version: Reusable travel vacuum bags with pump different from ordinary transparent plastic bags, black is more private and can be recycled many times. The surface is scratch-resistant and will not age, scratch or leak. Protect items from external pressure during transportation or home arrangement. Whether in a humid environment or outdoors in the rain, it effectively prevents gas and liquid from penetrating.
