Large Capacity USB Backpack: 36-55 Litre Waterproof Oxford Cloth Travel Rucksack

This multifunctional USB backpack is designed as a practical solution for travel, commuting, and leisure activities where reliable storage and device charging are needed. Its core appeal lies in the combination of a substantial 36 to 55-litre capacity, durable waterproof construction, and integrated USB functionality. The urban simplicity style and neutral gender design make it a versatile choice for a wide range of users seeking a dependable, feature-focused rucksack for everyday adventures and organised trips.
Construction and Material Details

The backpack's build prioritises durability and weather resistance. It is constructed from specific materials chosen for their practical performance in travel scenarios.
Oxford Cloth Exterior
The main body of the backpack is made from Oxford cloth, a fabric known for its sturdiness and resistance to abrasion. This material contributes to the product's waterproof quality, helping to shield contents from light rain and moisture during travel. The construction includes sewing thread details, which are noted as a popular design element, suggesting a focus on clean seams and finished appearance.
Polyester Lining and Straps
Inside, the backpack features a polyester lining. Polyester is a commonly used lining material appreciated for its smoothness and resistance to tearing, helping to protect the backpack's interior and the items stored within. The bearing system utilises curved shoulder straps, a design intended to better distribute weight across the shoulders and back compared to straight straps, enhancing comfort when the pack is fully loaded.
Capacity and Functional Design

This backpack is built around adaptable storage and modern convenience features, targeting users who need to carry a significant amount for day trips or longer travel.
Adjustable 36-55 Litre Capacity
The backpack offers a variable capacity ranging from 36 to 55 litres. This flexibility allows it to function as a larger pack for extended travel or a more compact option for shorter excursions, adapting to the user's specific packing needs on different occasions. The internal organisation is designed to support this volume efficiently.
Integrated USB Port Function
A key functional feature is the integrated USB port. This allows users to connect a power bank stored inside the backpack to a cable port on the outside, enabling convenient charging of mobile devices like phones or tablets while on the move, without needing to open the main compartment.
Style, Colour and Practical Use

The design ethos is centred on straightforward utility and broad appeal, avoiding overly specialised styling to maximise its use-case range.
Urban Simplicity Style
The backpack follows an urban simplicity style, characterised by clean lines, solid colours, and a lack of excessive embellishment. This makes it suitable for city commuting, campus use, and casual travel, as it presents a neat and functional aesthetic.
Neutral Colour Options
It is available in three solid colour choices, all under the code 2233#: Black, Red, and Sky Blue. This palette offers classic, bright, and light options to suit different personal preferences. The design is explicitly noted as applicable to both men and women, reinforcing its unisex, neutral-gender appeal.
Intended Use Scenarios
The primary applicable scenario stated is leisure travel. This covers activities like weekend trips, sightseeing, hiking, and general day-out adventures where carrying water, layers, electronics, and personal items is required. Its feature set makes it equally viable for daily commuting, campus life, or as a carry-on bag for shorter flights.
