Expandable Travel Backpack with USB Port Water-Resistant 17-inch Laptop Compartment Multiple Pockets for Carry-on Business and Travel

The day the office backpack becomes weekend luggage

That moment on Friday evening when your laptop backpack suddenly needs to become luggage for two nights. The return flight where the souvenirs you bought no longer fit in the space they occupied on the outbound flight. The business trip where you don't want to juggle a trolley and a shoulder bag at the airport. This travel backpack switches between both roles with a single zipper: slim as a commuter backpack, expanded as weekend luggage with a laptop compartment.

What makes this travel backpack different

• Expansion zipper for additional volume – A side-running zipper increases the main compartment from 37 L to 45 L. When closed, the backpack fits through tight carry-on checks; when open, it accommodates additional weekend clothing.
• Built-in USB port with internal wiring – A power bank (not included) is placed inside, and the cable leads to a USB port on the outside. You can charge your phone at the airport or on the train without having to take off your backpack.
• Padded laptop compartment for devices up to 17 inches – The compartment is close to the back, padded, and has its own zipper opening. At security checks, the laptop can be removed without completely unpacking.
• Water-repellent polyester outer material – Sudden rain, a spilled coffee at the airport, or slush on the platform beads off the material instead of soaking through. Internal electronics remain dry.
• Side compression buckles – If the backpack is not fully packed, the buckles pull the outer walls together and stabilize the luggage. The contents no longer slide back and forth inside.
• Water bottle pocket made of stretchy material on the side – A water bottle, thermos mug, or folded umbrella is easily accessible on the outside, without taking up space in the main compartment.
• Multiple separate interior compartments – Cables, travel documents, toiletries, and changes of clothes are separated from each other. You don't have to empty the main compartment to get to your passport.
• Top carry handle and padded shoulder straps – At the airport counter, the backpack can be lifted by the handle like a bag, and carried on your back during transit. The padding distributes the weight evenly, even when fully loaded.
• Trolley sleeve on the back – The backpack can be slid over the telescopic handle of a rolling suitcase and stays fixed there, instead of sliding off the suitcase with every step.

Who it's for

For commuters who switch between office and weekend trips during the week and don't want to juggle two bags. For business travelers on short-haul flights who want to keep their luggage within carry-on dimensions while carrying a laptop plus a change of clothes. For students with a laptop, documents, and sports gear for the week. For weekend travelers who want to travel without checked luggage. And for anyone who wears a backpack in everyday life that can become a travel bag when needed.

Pack, expand, connect

In standard mode, keep the expansion zipper closed – the backpack remains in the 37 L format and fits through standard carry-on templates. For longer trips, open the side zipper; the main compartment expands by approximately 8 L. Place your laptop in the padded back compartment, passport and tickets in the upper security compartment, clothes and toiletries in the main compartment. Before the first USB use, place your own power bank in the internal holder, connect the supplied connecting cable to the power bank and the internal USB input – you can then charge your phone at the external port. Before the flight, check whether the power bank you are carrying is below the airline's watt-hour limit; common 10,000–20,000 mAh models are permitted in most cabins. If the outer material gets dirty, wipe it with a damp cloth and mild soapy water; do not machine wash to preserve the water-repellent coating.

For everyone who wants to go to work, the airport, and the weekend with a single backpack.
