# SZLX Vacuum Compression Travel Backpack with Pump, 40 × 30 × 20 cm

The SZLX Vacuum Backpack is a travel rucksack with a vacuum-compression compartment and an electric pump. Its listed 40 × 30 × 20 cm dimensions and 14-inch laptop capacity suit buyers considering compact cabin luggage, but compression cannot guarantee that a packed bag will remain within an airline’s size limit.

- Vacuum-compression compartment is designed to release air through a valve, with electric pumping or manual air release described.
- Pump listing says it can inflate and deflate and includes different nozzles. It charges via USB-C.
- A dedicated compartment is listed for laptops up to 14 inches.

## Before you buy

- The listing is inconsistent about dimensions: it gives 40 × 30 × 20 cm in the feature text and size variant, while the dimensions field says 20D x 40W x 20H centimetres. Check the selected variant and airline rules, as loaded dimensions can differ. The claims that it meets Ryanair’s maximum and fits under a seat are not independently confirmed. The pump is described as included in the title and variant, but no explicit package inventory is supplied. The customer summary also reports mixed functionality and durability, including a snapped plastic handle on first use, without establishing how common these experiences are.

## A good fit for

- Travellers looking for a compact-format backpack with a vacuum-compression compartment and pump.
- People who want a separate compartment for a laptop up to 14 inches.
- Weekend travellers who may make use of the wet/dry organisation and suitcase strap.

## Less suited to

- Buyers needing a confirmed airline-approved fit for every packed load or carrier.
- Those carrying a laptop larger than 14 inches.
- Anyone who needs consistently effortless access to the compression compartment.

## Customer feedback

Customer feedback describes the backpack as convenient for travel, with positive reports about its quality, size and storage capacity. Some customers say it holds multiple items, including two pairs of shoes, and one reports using it for a five-day trip. Functionality and durability feedback is mixed, including reports that it did not work as expected and a plastic handle snapped on first use. These concerns matter particularly because compression is a central feature and the listing gives no independent performance or durability evidence. Overall ratings lean positive but include a substantial middle and lower-rated share, so they do not remove those practical uncertainties.
- Positive themes: Customer feedback mentions convenient travel use, storage capacity and a suitable size.
- Negative themes: The customer summary reports a snapped plastic handle during first use.
- Mixed feedback: Functionality feedback is mixed, with some customers saying the backpack did not work as expected.
- Mixed feedback: Durability feedback is mixed.
