40 Litre 17.3-Inch Laptop Backpack

This 40 litre backpack fits laptops up to 17.3 inches in a dedicated padded compartment. Water-resistant tear-resistant fabric and double metal zippers give a sturdy exterior for daily use. Four main compartments and two elastic side pockets organise books, clothes, bottles and small accessories. Suitable for students, commuters and travellers who need high capacity in a single bag.

USB Pass-Through Charging Port

An external USB-A port connects to an internal cable so you can plug your own power bank inside and charge devices without opening the bag. The port delivers only the current your power bank supplies; no battery or charger is included. Cable length is fixed by the built-in routing and cannot be replaced separately. Charging stops when the power bank is empty or disconnected.

19.1 by 13.8 by 11.4 Inch External Dimensions

The bag measures 19.1 inches tall, 13.8 inches wide and 11.4 inches deep, defining the maximum item size it can hold. Rigid panels and thick padding reduce internal volume slightly compared with the external footprint. Buyers needing to carry objects larger than these three dimensions should consider a larger bag or a different carrying solution.
