Allentian SJ03 13-15.6 inch laptop backpack

This Allentian SJ03 backpack fits laptops from 13 to 15.6 inches and suits commuters or students who carry a device plus daily essentials.

Check laptop dimensions and power bank needs

Measure your laptop to confirm it sits within the 13 to 15.6 inch screen range and the 45 x 30 x 15cm internal space. The external USB charging port and headphone jack require your own power bank and wired headphones; neither is included. Ensure you have a compatible cable to connect the internal power bank to the port.

Waterproof polyester build with ergonomic straps

The double-strand polyester fabric resists water and daily abrasion. Ergonomic strap design distributes weight across the shoulders and back to reduce strain during long carries. The external USB port and headphone jack sit on the outside for quick access without opening the main compartment. All seams and zippers are built for repeated use.
