Questions about this item
Does the backpack come with a power bank for the USB charging port, or do I need to buy one separately?
The USB charging port is a pass-through only; you must supply your own power bank and place it inside the backpack to use the port.
Should I rely on the 22 L capacity or the expanded 35 L capacity for a five-to-seven-day business trip?
The bag normally holds 22 L and expands to 35 L when the outer zipper is opened, so the larger volume is available when you need extra space for a longer trip.
Will a 17.3 inch laptop fit securely in the dedicated compartment without sliding around?
Yes, the separate laptop compartment is designed to hold a 17.3 inch laptop and protect it from moving during travel.
