Choosing a 15.6-inch laptop backpack: practical buying tips and popular picks

A 15.6-inch laptop backpack needs to do more than just hold your laptop. Students often carry books and chargers, commuters travel by bike or train, and business travellers want to keep documents and clothes organised. However, marketing claims can be difficult to assess.

Three common pitfalls are:

  • Judging a laptop compartment by screen size alone. A 15.6-inch laptop may still be too wide or deep for the compartment because of its casing.
  • Confusing “waterproof” with water-resistant. Many product descriptions only mention a water-repellent or water-resistant outer layer. That does not guarantee protection in prolonged rain or if the bag is submerged.
  • Overestimating security features. A combination lock, hidden pocket or lockable zip may help deter unwanted access, but none can guarantee that your bag won’t be stolen.

What should you look for in a laptop backpack?

1. Check the dimensions of the laptop compartment

Don’t just look for “fits 15.6-inch laptops”. Check the compartment dimensions and measure your own laptop too. A laptop backpack with a padded compartment provides a physical barrier against scratches and minor knocks, but a good fit is still important.

For example, the Case Logic Era ERACV-116 has a laptop compartment measuring 385 × 265 × 31 mm and is designed for laptops up to 15.6 inches. A travel laptop backpack may also need extra room for a charger, mouse, headphones and documents.

Check models where the title and specifications don’t fully match, too. The Lenovo ThinkPad Professional is described in the product name as suitable for 16-inch laptops, while the description mentions protection for laptops up to 15 inches. Always check the latest product specifications and your laptop’s dimensions before ordering.

2. Choose capacity to suit your daily routine

A slim laptop backpack is handy for commuting, but may not have enough room for a lunch box, books or clothes. A larger laptop backpack is more practical for travelling, but gets heavier once you fill all its compartments.

Look out for:

  • Capacity in litres: the HP Travel has a capacity of 25 litres and can be expanded to 30 litres, according to the product information.
  • Compartment layout: separate compartments for a tablet, documents, cables and small accessories help keep everything organised.
  • Bag weight: a lightweight bag leaves more room within your overall carrying weight.
  • How it’s carried: adjustable, padded shoulder straps are useful if you travel with your bag every day.

For a business laptop backpack, a separate document compartment and a carry handle are often more important than a large main compartment. If you regularly travel with a suitcase, a trolley strap is also useful.

3. Be realistic about water resistance and security

A water-repellent laptop backpack may help protect against light rain, depending on its construction and fastening. Check whether the product information describes it as water-repellent, water-resistant or waterproof. These terms are not interchangeable.

It’s worth taking a realistic view of anti-theft laptop backpacks, too. A lockable zip or detachable combination lock can provide an extra deterrent. According to KONO’s product information, the lock is intended as a deterrent and does not provide absolute security. Don’t leave your laptop backpack unattended, even when all the zips are closed.

A laptop backpack with a USB port only works when you connect a suitable power bank and cable. The USB connection is a charging pass-through and does not contain a built-in battery. Use a certified power bank and check that the connection is compatible with your devices.

Frequently asked questions about 15.6-inch laptop backpacks

Will every 15.6-inch laptop fit in every laptop backpack?

No. Screen size is only one factor. The casing can vary from one model to another. Measure your laptop’s width, depth and thickness, then compare these measurements with those of the laptop compartment. Remember to allow for a protective case, too.

How long does a laptop backpack last?

Its lifespan depends on the material, zips, seams, how heavily it’s loaded and the conditions in which it’s used. Don’t overfill the bag, use both shoulder straps and clean stains with a soft, damp cloth if the product information recommends it. Many products are covered by the minimum two-year legal guarantee of conformity in the European Union; additional manufacturer terms may vary.

Does a laptop backpack with a USB port cost more to use?

The USB port itself doesn’t use any power. You’ll need your own power bank and a suitable cable. So running costs mainly depend on whether you already own a power bank or need to buy one. Always check the safety instructions and don’t leave electronic devices charging unattended.
