Choosing a 15.6-inch laptop backpack: how to avoid a bad buy

Choosing a 15.6-inch laptop backpack might seem straightforward at first. But models can vary considerably in protection, layout and carrying comfort. A backpack may look spacious, yet still have too little room for a laptop, charger and documents. Terms such as “waterproof”, “anti-theft” and “USB charging” don’t always mean what you might expect, either.

For students, commuters and business travellers, these are the three main pitfalls to watch out for:

  • A 15.6-inch label doesn’t guarantee a fit for every laptop. Laptop dimensions vary by make and model, so always check the measurements of the laptop compartment.
  • Water-resistant doesn’t mean waterproof. A coating may help repel light rain, but seams, zips and prolonged exposure to rain can still be a concern.
  • A USB port won’t charge your device on its own. You’ll need your own power bank and cable. The port is mainly a pass-through connection to the power bank inside the backpack.

Which specifications matter?

1. Laptop compartment and internal dimensions

Don’t just look for “15.6 inches”. Check:

  • the maximum laptop size in centimetres;
  • whether the compartment is padded;
  • how the laptop compartment closes;
  • the space between the laptop compartment and the bottom of the bag.

A separate, padded compartment helps prevent your laptop from coming into direct contact with other belongings. For a business backpack, compartments for A4 documents, a tablet and a charger are useful too. If you’re unsure, measure the length, width and thickness of your laptop and compare them with the product size chart.

2. Water-resistant fabric and zips

A water-resistant laptop backpack is suitable for everyday use in changeable weather, but check exactly how its protection is described. “Water-repellent” or “water-resistant” usually means the fabric is less likely to absorb water. It doesn’t guarantee that water won’t get in during prolonged or heavy rain.

Also look for:

  • covered or secure-closing zips;
  • a water-resistant outer layer;
  • a base that’s easy to clean;
  • care instructions, such as wiping it with a damp cloth.

Some brands state in their product information that a backpack is water-resistant, but not fully waterproof. Consider keeping important documents in an additional cover.

3. Comfort, capacity and security

A backpack for commuting can quickly become heavy when you add a laptop, adapter, lunch and water bottle. Padded shoulder straps, a breathable back panel and an adjustable chest strap can make it more comfortable to carry. When carrying a heavy load, wear both shoulder straps and distribute the weight evenly.

An anti-theft backpack may offer extra protection with a hidden pocket, lockable zips or a combination lock. Treat these features as a deterrent, not as complete security. Never leave valuables unattended.

A laptop backpack with a USB port is handy when you’re out and about. Put your own certified power bank in an internal pocket and check that the cable fits securely. The power bank isn’t included with the KONO model, for example.

Frequently asked questions about 15.6-inch laptop backpacks

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

No, not always. Screen size is only one indication. Check your laptop’s length, width and thickness, then compare them with the internal dimensions of the laptop compartment. A protective sleeve may also need extra room.

How long does a laptop backpack last?

It depends on the material, zips, seams, weight carried and how often you use it. A backpack used for daily commuting will wear out more quickly than one used occasionally. Don’t overfill the bag, and follow the care instructions. Many models should only be wiped with a damp cloth and shouldn’t be put in the washing machine.

Is a USB port on a backpack safe for my phone?

The USB port is usually a connection between your own power bank and cable. The backpack itself doesn’t supply power. Use a suitable, certified power bank, check the cable and remove the power bank from the bag when you’re not using it.
