Inateck 17-20L Expandable Carry-On Laptop Backpack: size, features, fit

The Inateck BP03006-14-BK is a compact travel backpack from the brand's Lightour series. It is built to fit the smaller carry-on or under-seat limits that some airlines set, while still holding a 14-inch laptop and a few days of clothes. The main compartment can expand when you need extra room.

Size and expansion

Inateck gives the unexpanded size as 40 x 25 x 17 cm (about 15.75 x 9.84 x 6.69 inches), which is 17 litres. Opening the main compartment through 180° and expanding it takes the depth to 20 cm (7.87 inches), or 20 litres. Inateck compares the expanded capacity to a 20-inch suitcase. The extra 3 cm of depth is useful on the way home, but it also makes the bag deeper, so it matters if you plan to use it as a personal item under a seat.

Airline sizes

The brand states that the bag meets the carry-on requirements of many airlines and lists several North American carriers. Allowances differ between airlines and fare types, and they change, so check your airline's current size limits before you fly. Compare the unexpanded and expanded sizes with whichever limit applies to you.

Pockets and organisation

According to the listing, the layout includes:

• a side bottle pocket
• two zipper pockets on the front
• two zipper pockets inside the main compartment
• a compartment for laptops up to 14 inches
• an anti-theft zipper pocket on the back panel
• a card pocket
• a sunglasses hanging strap on the right shoulder strap

The back-panel pocket is against your body when you wear the bag, which is why that position is often used for passports and valuables.

Three ways to carry

The bag can be worn on both shoulders, carried by hand, or slid over the handle of a wheeled suitcase using the trolley strap on the back. The strap is helpful in airports, where you may pull a larger case and want your bag supported by it.

Comfort and materials

Inateck says the back panel uses air mesh for ventilation, and that adjustable chest straps help to spread the weight and steady the load. The fabric is polyester, which the brand describes as splash-resistant and wear-resistant. Splash-resistant is not the same as waterproof, so a heavy downpour could still reach the contents. A small dry bag or rain cover is an easy precaution for electronics.

Who it suits

It suits short trips, commuting, and carry-on-only travellers who like to pack light. It is less suited to anyone who needs to carry a larger laptop, as the dedicated compartment is listed for up to 14 inches.

What to check before you buy

• Laptop size: measure your laptop, including any case, against the 14-inch compartment.
• Airline limits: check the bag's expanded and unexpanded sizes against your airline's current rules.
• Weight: the listing gives about 1.7 lb (roughly 0.8 kg) empty, which counts toward any weight limit.
• Packing: 17-20 litres goes quickly, so think through what you need.
• Trolley strap: confirm your suitcase handle is compatible with the strap.
• Care: check the brand's guidance for cleaning.
