A 15.6-inch laptop backpack may seem easy to choose at first glance. However, models vary considerably in carrying comfort, protection, organisation and material. A backpack that looks spacious in the product photo may not offer enough room in everyday use for a charger, lunchbox or documents. Terms such as “water-repellent” and “USB charging port” are not always as comprehensive as they sound, either.
This buying guide will help you assess marketing claims and choose a laptop backpack for work, school, commuting or travel.
The 15.6-inch measurement usually refers to the diagonal screen size. However, the external dimensions of laptops vary by brand and model. As a result, a business laptop with wide bezels or a sturdy protective case may fit more tightly than expected.
So check:
A backpack for a 15.6-inch laptop is therefore no guarantee that every model will fit without difficulty.
A water-repellent laptop backpack will generally protect against light rain or splashes. The product title may mention water repellency, but that does not automatically mean the seams, zips and base are completely waterproof.
For cycling or long walks in typical British weather, these points are particularly relevant:
Do not use a water-repellent backpack as a substitute for a waterproof laptop sleeve when travelling through heavy rain for extended periods.
A backpack with a USB port usually has a pass-through that allows you to connect a power bank inside the bag to a device outside it. The power bank itself is generally not included unless this is clearly stated in the product information. The USB port also does not replace a laptop charger.
Pay attention to how it works in practice:
Think of the USB feature primarily as a convenience while travelling, rather than as a standalone power source.
A separate laptop compartment prevents your computer from being loose among your other belongings. Do not only look at the maximum screen size; also check the lining, fastening and position of the compartment. A compartment positioned close to your back can keep the laptop more stable while you walk.
For everyday use, a combination of a laptop compartment and a second compartment for documents or accessories is practical. If you often travel with a laptop, tablet and charger, several compartments will be more useful than one large, open main compartment.
A large laptop backpack does not automatically provide a well-organised layout. Check whether there are separate compartments for:
A slim business backpack is convenient on trains, buses or at the office, while an expandable travel backpack offers greater flexibility when you are carrying extra clothing or accessories.
Look for wide shoulder straps, an adjustable chest strap and a back panel that does not feel unnecessarily hard or flimsy. A lightweight bag avoids adding extra weight, but a construction that is too thin may offer less support when you are carrying a lot.
Canvas can give a bag a casual appearance. Synthetic materials are often easier to clean. With every model, look at the specific product description and user feedback rather than relying solely on terms such as “premium” or “business”.

No. Screen size is only one indication. Measure your laptop’s length, width and thickness and compare these with the internal dimensions of the laptop compartment. Take the protective case and the space required for the zip into account.
Its lifespan depends on the load, material, seams, zips and daily use. A bag that is constantly filled with heavy items will wear out faster than one carrying only a laptop and a few accessories. Clean the backpack according to the product instructions and do not put excessive strain on the zips.
The USB port itself generally uses very little power; the connected device is what mainly determines consumption. The required energy comes from the power bank inside the backpack. Total usage time depends on the capacity of the power bank, the connected device and the cable being used.
