# VANKEV Expandable Cabin Backpack, 45 × 34 × 20 cm

The VANKEV expandable cabin backpack is a soft-shell travel rucksack with a laptop compartment listed for devices up to 17 inches. Its expandable design is claimed to increase depth from 20 cm to 25 cm, trading a compact cabin profile for extra packing capacity when opened.

## At a glance

- Unzip the expansion section to increase the stated depth from 20 cm to 25 cm and capacity from 30L to 38L.
- Three compartments and nine pockets are listed, including a laptop compartment and a hidden anti-theft pocket.
- The listing describes RFID blocking, a luggage strap and a side cable opening. Power bank and cables are not included, according to the listing.
- The manufacturer claims the compartments can open 180° for packing and security checks.

## Pros

- Expandable layout offers a choice between a smaller profile and more packing space.
- The stated 17-inch device limit and multiple storage areas suit travel that combines a laptop with clothing and accessories.
- A luggage strap, quick-access pocket and claimed RFID-blocking pocket add useful organisation for trips.

## Cons

- Expanded depth is 25 cm, so using the full expansion may not suit cabin or under-seat limits that require a slimmer bag.

## Before you buy

- The listing gives conflicting capacity details: 34 Liters, 30L to 38L, and an expansion claim from 30L to 38L. It also presents 45 × 34 × 20 cm as the base size and 45×34×25cm when expanded. Check the selected airline's current size and baggage rules, especially if expanding the bag. The claimed fit for EasyJet, British Airways and Jet2 is not a guarantee of acceptance.

## A good fit for

- Travellers wanting a backpack that can expand for short breaks while carrying a laptop.
- Buyers who value separate storage pockets and a luggage strap for organising travel essentials.

## Less suited to

- Travellers who need a guaranteed cabin-bag allowance across airlines or plan to use the expanded 25 cm depth without checking current restrictions.

## Customer feedback

Customer feedback highlights perceived build quality and suitability for holidays or short breaks. That travel-friendly impression aligns with the expandable design and multiple compartments, while the mixed overall rating means experiences are not uniformly positive. Feedback does not establish performance or airline acceptance.
- Positive themes: Customers are reported to appreciate the build quality.
