VGCUB Vacuum Backpack with USB Port, Beige
This VGCUB vacuum backpack combines the range's compression system with a wet-dry separation pocket and an external USB pass-through. A power bank sits inside the bag and a phone charges from a port on the outside, so the bag stays closed and on the shoulders. The front panel measures 37 by 21 centimetres.
What this model is built around
The USB port is a pass-through, not a battery, and the distinction is worth stating plainly because it is the thing buyers get wrong. There is no cell in the bag and nothing to charge overnight. A power bank the traveller already owns goes into an internal pocket, plugs into the inside end of the cable, and a phone plugs into the outside end. What it buys is not power but access: on a transit day the bag never has to come off a shoulder or be opened in a queue.
Compression is the same system as the other compression models - a sealed bag inside its own compartment and a manual hand pump.
- External USB pass-through — connect a power bank inside, charge a phone without opening the bag
- Wet/dry pocket keeps a swimsuit or a damp towel away from the rest
- Anti-theft pocket against the back panel
- Built-in vacuum compression, the same system as the rest of the range

What it holds, and what it does not
The wet-dry pocket is the second practical detail. A swimsuit, a damp towel or clothing worn in rain goes in there and stays away from everything dry, which matters more on a short trip than most specification lists suggest. An anti-theft pocket sits against the back panel, where it is covered by the wearer's own body in a crowd.
The laptop compartment is padded. As with the rest of the models shown here, measure a machine's footprint rather than trusting its screen diagonal, because two laptops sold as the same size can differ by a couple of centimetres.
Who it suits
Choose it if
Long transit days where a phone runs flat and the bag stays on the shoulders.
Look elsewhere if
Anyone expecting a battery — the port passes power through, it does not store it.
Against the other models
Choose this one for long transit days where a phone runs flat. Choose the khaki model instead if footwear has to be kept apart from the clothing, or the 40-litre model if capacity is the deciding factor. All three carry the same compression system, so the choice is genuinely about the extra rather than about how well the bag compresses.
Every model, side by side, is on the home page, and the mechanics behind these specifications are in the reference guides.
Vacuum Backpack, USB FAQ
Does the USB port charge the phone by itself?
No. It is a pass-through. A power bank inside the bag supplies the power; the port only routes it to the outside so the bag can stay closed.
Is a power bank included?
No. The traveller supplies their own.
What is the wet/dry pocket for?
Damp items - a swimsuit, a towel, clothing worn in rain - kept separate from everything dry in the bag.
Does it have the same compression system as the other models?
Yes. A sealed bag in its own compartment, emptied by a manual hand pump through a check valve.
Where is the anti-theft pocket?
Against the back panel, so it sits against the wearer's body and is out of reach in a crowd.
