MATEIN 100800blk 50L Laptop Backpack for 17.3-Inch Laptops

The MATEIN 100800blk laptop backpack is listed with 50-litre capacity, a padded compartment sized for laptops up to 17.3 inches and more than 20 pockets. Its spacious layout and padded straps suit travel, study or work, but listed size and model details vary across the page, so confirm the exact variant before buying.

At a glance

The listing describes three spacious main compartments and more than 20 pockets for separating travel or study items.
A padded laptop compartment is claimed to fit devices up to 17.3 inches. Actual fit depends on a laptop's dimensions, not screen size alone.
The feature description says it opens 90–180 degrees for airport security checks. This does not establish airline cabin-bag compliance.
Padded mesh shoulder straps and a ventilated back panel are described for carrying comfort.

What to know before buying

Listing details to confirm

Listing details are inconsistent: the title and laptop-size fields say 17.3 inches, while feature text mentions sizes up to 17 inches. The dimensions are listed as 10.2D x 20.1W x 15H centimetres, but another description gives 20x14.9x10.2 inches. Model identifiers also differ, with 100800blk in the model field and 100802BLK elsewhere. Confirm the exact variant, measurements and laptop fit on the selected listing. Water resistance is claimed, but the page does not establish waterproof performance.

Who is it for?

A good fit for

Travellers, students or commuters who want a high-capacity backpack with separate laptop storage and extensive organisation.
Buyers carrying a larger laptop who can confirm its measurements against the compartment before purchase.

Less suited to

People seeking a compact, lightweight day bag with minimal storage.
Anyone who needs confirmed waterproofing, exact cabin-bag compliance or a guaranteed laptop fit based only on screen size.

Customer feedback describes the backpack as spacious and functional, with positive comments on build, design and value. Durability experiences are mixed: some find it robust, while others report shoulder straps coming apart after one use. For buyers using the claimed 50-litre capacity, that disagreement matters if the bag will regularly carry a heavy load. Aggregate ratings lean positive overall, but ratings alone do not explain individual experiences.

Positive themes

Customers report that the backpack is spacious and useful, including feedback describing room for a 17-inch laptop and a 15-inch laptop in the rear pocket.
Feedback also praises its perceived build quality, design and value.

Negative themes

Some customers report that shoulder straps came apart after a single use.

Mixed feedback

Durability feedback is mixed, with some customers describing the bag as robust and others reporting strap failure.

Frequently asked questions

Will it fit a 17.3-inch laptop?

The title and compatible-device field state 17.3 inches, but feature text refers to laptops up to 17 inches. Check your laptop's physical dimensions against the selected version's compartment measurements.

Is the backpack waterproof?

The listing calls it water resistant and describes water-resistant materials and a zipper. It does not establish that the bag is waterproof.

Can it be used as an airline cabin bag?

The description claims a 90–180-degree opening to help with airport security checks. It does not confirm compliance with any airline's cabin-bag size rules.

How should it be cleaned?

The listed care instruction is to wipe it with a damp cloth.
