SZLX Vacuum Backpack Travel Bag with Pump – Cabin-Friendly, 40x30x20 cm with 14-Inch Laptop Space
Product description
What it is and what it’s for
The SZLX Vacuum Backpack is designed as a compact travel bag that doubles as a lightweight cabin option with built-in vacuum compression. It aims to help travellers maximise space by expelling air from vacuum bags through an outlet valve, creating extra room for clothes and essentials on short trips. It also includes a practical laptop compartment and multiple pockets to keep items organised during flights and on the move.
How it works and practical use

The bag comes with an integrated vacuum pump, so you don’t need to buy a separate device. You can choose between fast electric compression or manual air release, which can save space when stowing within overhead lockers or under seats. The pump is charged via USB and Type-C, and various nozzles are supplied for different tasks. In use, you’d typically pack clothes in supplied or compatible vacuum bags, seal them, and pump to remove air before closing the airtight zip.
Design and comfort in use
Externally, the bag measures 40x30x20 cm, aligning with Ryanair and some Wizz Air cabin allowances, and it weighs about 1 kg. The back panel is padded with a honeycomb design and a breathable material, intended to cushion the load, while the shoulder straps are cushioned for comfort on longer travel days. A back zip pocket provides secure storage for valuables, and there’s a luggage strap to attach the bag to a rolling suitcase.



What stands out on paper
The vacuum feature and the included pump remove the need for an extra purchase, which is convenient for travellers who want to keep packing simple. The 180° opening enhances packing and access, turning the bag into a kind of flexible suitcase for quick stowage and retrieval. A dedicated laptop compartment helps protect a 14 inch device, which is useful for business trips or study travel.
Limitations and caveats

One notable point is that the vacuum seal is described as very tight, which may require extra effort to open the airtight zip. The system relies on vacuum bags to realise its space-saving potential, without them, you won’t gain the same level of compression. The bag is pitched primarily for cabin use, so heavier packing or non-standard items could compromise comfort or fit in smaller aircraft cabins.
Who it’s for and who it isn’t ideal for
It’s well suited for travellers who value compact cabin luggage with the ability to maximise space and keep a laptop readily accessible. If you regularly carry bulky items or require a larger capacity than a typical under-seat bag, this model may feel limiting. It also depends quite a bit on whether your airline’s cabin bag rules align with the 40x30x20 cm footprint.



When it makes sense to buy
- You travel light but want to squeeze in a bit more by using vacuum compression.
- You value organisation and a dedicated laptop compartment within a compact bag.
- You prefer not to buy extra accessories, since the pump is included and USB rechargeable.
When to think twice

- If you aren’t able to use vacuum bags effectively or if you’re packing non-standard shapes, the space gains may be marginal.
- If your travel often requires larger or multiple carry-ons, a bigger pack might be a better fit in the long run.
- If opening the airtight zip is particularly fiddly for you, consider how often you’ll access the main compartment during a trip.
What to check before buying
- Confirm that the vacuum system and pump function reliably with standard vacuum bags you already own or plan to buy.
- Ensure the laptop compartment fits your 14 inch device with any protective sleeve.
- Consider your usual airlines and aircraft types to verify the cabin size compatibility beyond Ryanair, Wizz Air, and similar operators.



Practical usage snapshot
Imagine arriving at the airport, packing smartly in the bag, blasting a quick compression to reclaim space, and dutifully securing the pack under the seat or in the overhead bin. The back pocket keeps your passport handy, while the luggage strap helps you wheel it alongside a carry-on suitcase.
What you’ll notice day to day
Expect a well-organised interior and a pragmatic approach to packing: space-saving compression when needed, plus easy access to the laptop area and essentials. The Venturi-like vacuum design can feel like a clever workaround on short trips where every centimetre matters.
FAQ (based on available information)
- Does the bag come with vacuum bags? Not specified, it emphasises a vacuum system and pump but does not confirm included bags.
- What size laptop fits? A 14 inch laptop fits in the dedicated compartment.
- Is the pump USB-C rechargeable? Yes, it’s charged via a Type-C USB connection.
Is it worth it?
Worth considering if you prioritise cabin-friendly packing with the convenience of an integrated pump and a dedicated laptop sleeve, and you travel on airlines with similar cabin restrictions. If your packing needs are more extensive or you require larger capacity, it may not be the best fit. A solid choice for efficient, compact travel rather than a high-capacity luggage solution.
