Expandable USB Charging Backpack for 15.6-Inch Laptops

Expandable USB Charging Backpack for 15.6-Inch Laptops

This expandable business backpack carries as a backpack, top-handle bag, or single-shoulder bag, and its built-in USB port lets you charge a phone on the go from a power bank stored inside, ideal for daily commuting and travel with a 15.6-inch laptop.

Expandable Capacity: A single zipper pull adds 6cm of depth, taking the main compartment from 26L to 39L for extra packing space when needed.

USB Charging Port: An external USB port connects to a power bank stored in an interior pocket, so a phone can charge without opening the bag.

Water-Resistant Oxford Fabric: The scratch-resistant, fadeless nylon exterior sheds light rain and holds its color with daily use.

Organized Storage: A padded 15.6-inch laptop sleeve, front zip pockets, and two side mesh pockets keep a laptop, water bottle, and accessories separated.

Trolley Sleeve: A rear strap fits over a rolling suitcase handle for easier movement through airports.

Nice Bags manufactures this expandable backpack under OEM/ODM programs, offering custom fabric, color, and branding options for business bag brands and corporate gift orders.
