Compress a Week's Wardrobe into a Carry-On
This pocket‑sized vacuum pump weighs 84 g and uses a -50 kPa pull to extract air from fabric, shrinking a stack of sweaters, jackets, and jeans to roughly 20% of its original volume in about 15 seconds.
Powered by USB‑A or USB‑C sources you already carry, it works with a laptop, power bank, wall charger, or your phone charger. The unit measures 4 cm by 13 cm and weighs less than many paperbacks.
Sealed bags keep clothes dry, dust‑free, and mildew‑free while you travel, so garments exit the journey looking as fresh as when they went in—and you avoid baggage claim crumple.
VoltPack uses a universal valve that fits nearly all vacuum bag types, and it runs directly from USB power instead of traditional hand pumps. If a bag wears out, you can swap to replacement bags without replacing the pump, and it operates with less noise than many fan‑style pumps.
How a compact 4 cm × 13 cm device delivers carry‑on level suction: a -50 kPa vacuum draws air out from a stack of clothing until it sits at about one‑fifth of its former size, allowing a nine‑pullover pile to occupy the space of a single folded shirt.
The Quick Breakdown
- Packs a full 7‑day wardrobe into a personal‑item backpack or a single carry‑on
- Eliminates the need for pricey checked‑bag fees from your second flight onward
- Return trip: bags and pump fit back inside your suitcase for easy re‑use
Pack Your Trip in 4 Simple Steps
- Fill the bag by folding and stacking clothes inside, leaving about 2 inches at the zipper.
- Seal the zipper with the included slider clip, running it twice to lock the seam.
- Pump the air out: place VoltPack on the valve, press start, and wait 10–15 seconds until flat.
- Close the valve by twisting the red cap; the compression remains through the trip.

Will the bags stay compressed during the flight? Yes. After you twist the red valve cap closed, the seal holds for the entire journey with no slow reinflation in overhead bins.
Is this kit suitable for storing bulky bedding or comforters? Not designed for large household items; VoltPack targets travel clothing only. For bulky bedding, a larger home vacuum storage kit is recommended.
In practice, the kit supports dozens of trips under normal use, and when a valve eventually fails, the universal pump accommodates replacement bags.
