PUSLOM Ryanair cabin-size underseat backpack 40x30x20 with USB charging port (Grey)
Product description
The essentials (and the problem it’s meant to solve)
If you’re trying to travel light and avoid the usual stress at the gate, cabin-size dimensions matter. This PUSLOM underseat travel backpack is built around a 40x30x20 cm “cabin bag” footprint, with an overall capacity claimed at 24L. On paper, that’s the sweet spot for Ryanair-style limits, and it’s also positioned as suitable for other major airlines’ cabin rules.
You also get a fairly complete internal layout for a bag of this size: a main zipped compartment with a compression strap, a front compartment that’s meant to organise small items, a dedicated padded laptop pocket, side mesh pockets for water bottles or an umbrella, plus a back zipped pocket for valuables. There’s even a separate “wet pocket” area for toiletries or items that need to stay separate.
It’s not trying to be a weekend rucksack you can cram with everything you own. It’s more “small trip, keep it neat, keep it hand-luggage friendly”. That’s where it tends to make the most sense.
Key features that you’ll notice day to day
Where this bag feels practical is in the way it’s organised for real journeys, not just a generic compartment layout.
- Wet pocket for toiletries or damp items. The wet pocket is made from high-density waterproof material, intended for wet towels or toiletries.
- Dedicated padded laptop compartment. It’s described as fitting 13/14 inch laptops, with a separate padded area designed to make it quicker to take in and out.
- Compression strap in the main compartment. It helps keep the contents from “puffing out” when you pack tightly, which is useful when you’re trying to stay within carry-on limits.
- USB charging port with built-in cable. There’s a charging cable built in, so you can route power to a phone or other device while you walk (you’ll still need your own power bank).
- Anti-theft zippered back pocket. A hidden pocket on the back is meant for valuables.
- Luggage strap for trolley handling. If you use airport luggage trolleys, the strap lets the backpack slide over the upright handle tube.
- Comfort for shoulder carry. It uses an airflow back design with breathable mesh and multi-panel ventilated sponge padding, plus wide adjustable shoulder straps and a foam-padded handle.
A small thing, but worth calling out: the chest fixed buckle is described as helping reduce “weight of loading”, which should take a bit of pressure off your shoulders when the bag is reasonably full.
What matters most for buying: fit, storage, and limitations
This is the kind of travel backpack that’s easier to recommend if your travel plan matches its size and layout.
It’s a good fit if you want a compact underseat/cabin rucksack for short breaks and you’ll be packing items like clothes, a book, a few tech essentials, and toiletries. The “3–4 days” use case is explicitly suggested in the description, and the compartment mix supports that (main compartment + front organiser + laptop pocket + wet pocket).
It may not suit you if you’re the type who needs a lot of bulk storage or you routinely carry bulky items you can’t compress. Also, because the size is specifically focused on cabin rules, it can feel a bit tight for longer trips unless you pack very strategically.
There’s also one practical limitation to keep in mind: while the bag includes a USB charging port, the bag itself can’t create power—so you’ll want to plan for a compatible power bank.
Who it suits (and who should think twice)
This bag is pitched as a cabin rucksack for modern travellers, and in practice it looks made for people who are organised and value quick access.
You’ll likely like it if: - you carry a laptop while travelling and want it in a separate padded compartment - you prefer a wet compartment for toiletries or damp items - you like having side access for water bottles/umbrellas rather than everything living in the main space - you want a backpack that can handle short trips without feeling oversized
It might not be for you if: - you want maximum carry capacity beyond cabin constraints - you don’t plan to use the extra pockets (then a simpler bag might be better value) - you prefer a roll-top or very minimal carry style (this one is more structured and compartment-led)
Quick practical example (how you might pack it)
Say you’re heading away for a few days with a laptop and basic toiletries. You could keep your clothes and everyday items in the main zipped compartment using the compression strap to keep things compact. Your laptop goes in the padded laptop section so it’s easier to grab quickly when you need it. A small organiser-style front compartment works for pens, charger cables, and small accessories. Toiletries stay in the wet pocket so nothing spills onto dry clothes. Finally, you keep your valuables in the back zip pocket where they’re harder to access when the bag is on your back.
That’s the “small trip” workflow this bag is built around.

Is it worth it?
This PUSLOM backpack looks worth considering if you’re specifically targeting a 40x30x20 cabin-size travel bag for short breaks, and you want more than “one big pocket” thanks to the wet pocket, organiser front section, and separate padded laptop compartment. The trolley strap, breathable back padding, and anti-theft-style back pocket also align well with frequent hand-luggage travel.
However, it’s not the best choice if you regularly need larger capacity or you want a very flexible, minimalist pack. For people who pack tightly and value organised access, it should feel like a sensible, practical cabin rucksack.
