Product details
Expandable USB Travel Backpack for Men
An expandable travel backpack with a USB connection port and a laptop compartment described for 17.3 in devices. Choose the current 37 L or 45 L label and color for your packing arrangement, then confirm the actual dimensions and device fit.
- Current 37 L and 45 L capacity labels
- Laptop compartment reference up to 17.3 in
- Expandable format; USB port and multiple interior pockets
Choose the capacity label for your travel load
The separate capacity options help distinguish the selected backpack configuration before packing. Interior pockets give the laptop, phone and smaller accessories their own positions, while the expandable format offers a packing feature to check on the chosen version.
Choose the actual capacity option
The selector distinguishes 37 L and 45 L versions, with several colors for each. Confirm the expansion range of the selected model rather than assuming one bag necessarily expands from 37 to 45 L.
Keep the laptop in a dedicated compartment
The 17.3 in reference gives a screen-size starting point for the laptop section. Compare the actual compartment dimensions with your device’s width, depth and thickness before choosing.
A connection port for compatible charging
The USB port offers a connection route when a suitable power source and cable are arranged. Confirm contents and electrical requirements; the port itself is not a battery.
