Hayayu for Easyjet Cabin Bag 45x36x20: Underseat, Water-Resistant Travel Backpack with Charging Port
Product description
What it is
The Hayayu for Easyjet Cabin Bag is a compact, water-resistant underseat travel backpack designed to meet EasyJet’s cabin size guidelines (45x36x20 cm) while offering practical features for everyday flying. With an estimated 31 litres of capacity, it aims to balance bag space with the need to avoid extra charges when travelling light.
Who it’s for

If you frequently travel on short-haul flights and value a bag that sits under the seat, this model may suit commuters, weekend travellers and casual flyers who carry a laptop, a few outfits and essentials. It’s also compatible with other carriers that accept similar underseat dimensions, though you should always double-check individual airline rules.
What stands out


On paper, several design touches stand out: a dedicated 15.6-inch laptop compartment, internal wet/dry separation, and a back anti-theft pocket for valuables. The bag includes internal organisation such as a packing tape for tidying clothes and small mesh pockets for phone or passport. A charging port feature lets you power devices on the move by connecting an external battery, without having to rummage through pockets.

What to watch out for
While the specification is practical, real-world comfort hinges on how the load sits on your back. The straps are described as widened and thickened, with mesh padding to help distribute weight, but comfort will depend on your frame and how much is packed. The bag is marketed as durable and water-resistant, yet the level of water resistance and long-term wear should be considered if you frequently travel in poor weather or rough handling conditions.
How it fits into your luggage strategy

If you prioritise underseat capacity with a laptop pocket and a charge-while-travelling setup, this bag can sit in your toolkit as a reliable day-to-day carry-on. It isn’t pitched as a feature-rich premium backpack, rather, it focuses on practical organisation, safety pockets and travel convenience.


Pros and Cons in practice
Pros: - Meets EasyJet underseat dimensions and offers a main compartment with 31 litres capacity. - Separate laptop pocket for up to 15.6 inches, plus wet/dry separation for easier packing hygiene. - Water-resistant exterior and reinforced build, with a dedicated anti-theft pocket for valuables. - Integrated charging port option to power devices on the move.

Cons: - Comfort and ergonomics depend on the wearer’s build and packing style, some travellers may want more substantial cushioning for longer trips. - The charging port feature requires an external battery, you’ll need to supply and manage that separately. - It’s a practical, not extravagant, option—may not satisfy travellers seeking high-end materials or super-lightweight design.
What to check before you buy
- Confirm the exact airline requirements for cabin baggage if you mix carriers on a trip.
- Consider how you intend to accessorise with a power bank and whether you’ll need a dedicated USB-C/USB-A setup.
- Think about your typical on-board gear: will the 31-litre capacity comfortably hold clothes for your trips, or will you need to pack more efficiently?



How it compares to other approaches
This bag sits between a compact everyday backpack and a dedicated travel luggage option. If you want something truly lightweight or with more rigid structure, alternatives within similar dimensions may prioritise one or the other. If your priority is organisation and a security pocket plus a charging port, this model offers those pragmatic features without moving into premium-tier pricing.
Practical use case

Imagine a two-day city break: you pack a couple of outfits, a compact toiletries kit, a laptop for work, and a light jacket. The laptop pocket keeps the computer protected, the packing tape helps you squeeze in essentials neatly, and the anti-theft pocket holds a passport and wallet. You can charge your phone using a battery stored in the bag, without having to search pockets mid-journey.
FAQ
- How much can you fit in this bag? About 31 litres, within the EasyJet cabin size range, though actual space depends on packing style.
- Can it go under the seat on most flights? Yes, as designed for underseat use, and suitable for several other airlines with similar dimensions.
- Is the charging port ready to use out of the box? It supports charging with an external battery, you’ll need to supply your own power bank.
Is it worth it?
It’s a solid pick if you want a practical, underseat backpack with organised compartments and an anti-theft pocket, plus the convenience of a charging option. If your travel needs demand ultra-lightweight build, premium materials, or more expansive capacity, you may want to look at higher-tier options. In short, it makes sensible sense for regular short trips where underseat storage and device charging matter, but it may not satisfy travellers chasing top-tier materials or maximum luggage capacity.
