Extra Large 50L Laptop Backpack

The ProEtrade backpack provides 50 litres of storage across three main compartments and multiple pockets. It fits laptops up to 17.3 inches in a dedicated sleeve while the other sections organise clothes, documents and small accessories. The unisex black polyester design suits travel, work or daily use.

Opens 90 to 180 Degrees for Security Checks

The bag unfolds flat between 90 and 180 degrees to meet TSA screening requirements without removing the laptop. Double metal zippers run smoothly for quick access and an anti-theft pocket protects valuables. A top handle and luggage strap offer alternative carrying options.

USB Port Requires Separate Power Bank

An external USB charging port with built-in cable connects to your own power bank inside the pack; the bank is not included. A headphone port allows wired audio access without opening the main compartments. The polyester shell resists scratches but is not waterproof.

Questions about this item

How do I confirm the TSA-friendly opening works correctly after packing the 50L bag?

Unfold the backpack fully to 180 degrees; the main compartment should lay flat without forcing the double metal zippers.

What comes in the box and what must I supply for the USB charging port?

The backpack includes the built-in charging cable; you must provide your own power bank to use the external USB port.

Which capacity suits a 17.3 inch laptop plus overnight gear?

The single 50L version fits a 17.3 inch laptop in its dedicated compartment and leaves room for clothes in the second main compartment.
