Product guide

Aerolite TBPQU-SML-BLACK Quilted Underseat Trolley Backpack, 20L

Underseat: Aerolite TBPQU-SML-BLACK is a quilted cabin bag designed to work as a backpack, hand-carried holdall or wheeled trolley. Its 20-litre capacity, three zipped compartments and external USB port suit light travel, while the listed 2-kilogram weight is worth considering if you expect to carry it on your back.

At a glance

Three ways to carry it: roll it using the extendable handle, wear it as a backpack or carry it by the top handles.
Three zipped compartments include a main section with packing straps, a tablet pouch listed for screens up to 10.1 inches and a toiletries pocket described as waterproof.
The built-in USB port connects to your own power bank, which is stored inside the bag. The power bank is not included.
The manufacturer describes the outer material as showerproof recycled PET and says it is made from recycled plastic bottles.

Pros and cons

Pros

Convertible carry options can make the bag easier to handle across different parts of a journey.
Separate compartments, packing straps and a side water-bottle holder help organise a light travel load.
The external USB port lets you connect a separately supplied power bank without keeping it in a pocket.

Cons

The listed weight is 2 kilograms, a notable starting weight for a bag that can also be carried on the back.
At 20 litres, its capacity is aimed at travelling light rather than carrying a larger load.

What to know before buying

Listing details to confirm

Listing details are contradictory or inconsistent: the title and feature text identify Ryanair and Wizz Air compatibility and cite 40x20x25, while the highlighted listing text says 40x30x20. Dimensions are also shown as 40x20x25 and 25L x 20W x 40H centimetres. Confirm the selected bag's measurements and the airline's current allowance before travel. Water resistance is listed as “Water Resistant”, while the feature text calls the fabric showerproof. The power bank is not included, and the stated pocket fit is up to 18x8x2cm.

Who is it for?

A good fit for

Travellers packing light who want a bag that can be rolled, carried by hand or worn as a backpack.
Buyers who value separate compartments and an external USB connection for their own power bank.

Less suited to

Travellers prioritising a low carry weight, since the listed bag weight is 2 kilograms.
Anyone needing more than the stated 20-litre capacity or relying on unconfirmed airline dimensions without checking first.

Customer feedback praises perceived quality, appearance, portability and the option to use the bag as a backpack or trolley. Views on capacity and size are mixed, with some finding it smaller than expected, and some describe it as heavy. Those concerns are relevant to a 20-litre bag listed at 2 kilograms, especially if you plan to carry it on your back.
