A 15.6-inch laptop backpack may seem easy to choose at first glance. However, small design details can make a big difference. A bag that looks spacious in the product photos may offer very little room for documents in practice. A USB port only works when connected to a power bank, and “water-resistant” does not automatically mean that the contents will stay dry in heavy rain.
For women and men carrying a laptop, A4 documents, lunch and everyday essentials, three pitfalls are particularly important:
Do not just look at the 15.6-inch designation. Also check:
A spacious laptop backpack should also have room for a charger, mouse, documents and possibly a tablet. For school or university, an A4 compartment and a separate front pocket are practical. If you use the backpack as a backpack for work and school, a well-organised layout is often more useful than one large main compartment without dividers.
Pay attention to the precise description of the material. Terms such as water-resistant or “water resistant” indicate that, according to the product description, the fabric is intended to repel moisture to some extent. They do not guarantee that the bag is completely waterproof.
Also check the zips and seams. A high backpack opening or a flap can provide extra protection, but the construction determines how easily rain can reach the laptop compartment. If you cycle for long periods in poor weather, consider carrying a separate rain cover.
For a laptop backpack for commuting, adjustable shoulder straps, a breathable back panel and a carry handle are useful features. A trolley strap is handy if you regularly travel with a wheeled suitcase.
Also consider the weight of the empty bag. A model with lots of compartments and insulation may be heavier. This is not necessarily a problem, provided the layout suits what you carry every day.
A USB connection is usually located on the outside of the bag. In most cases, you need to place your own power bank in an internal pocket and connect it with the cable. Check which type of connection you need in advance. The presence of a USB port does not automatically mean that the bag itself supplies power.
Why it suits this profile: The flip-top opening, drawstring closure and spacious design make it suitable for everyday use at school, work and around the city.

Why it suits this profile: The slim, business-style design is intended for the office, travel and commuting. The USB port can be useful on the go when used with a suitable power bank.
The product description mentions both a water-repellent outer material and a USB charging port. The bag remains relatively straightforward, so you do not pay for a lunch compartment you do not need.

No. The screen size does not represent the laptop’s complete external dimensions. Check the length, width and thickness of your computer and compare them with the laptop compartment. Also allow room for a protective case, if you use one.
A water-resistant laptop backpack can help keep out light rain, but it is not automatically waterproof. A rain cover is advisable during prolonged or heavy rain. If important documents need to stay dry, place them in a separate protective sleeve as well.
The USB port is usually connected to a cable inside the bag. You place your own power bank in an internal compartment and connect your phone or another device to it. Before buying, check that your cable and power bank are compatible. The power bank is not normally included with the backpack unless this is explicitly stated in the product details.
Check the dimensions of the lunch compartment, the insulating materials and whether the compartment can be removed. A removable lunch compartment makes the backpack more versatile: on days when you do not take lunch, you can carry more documents or clothing. Also consider the total weight, especially if you use the bag every day.
