Comparison Xiaomi 90 Points A1 Suitcase 20 vs Wenger Tresa 100

The total volume of the suitcase in liters. On the one hand, the number of things that can be placed inside depends on this parameter, and on the other hand, the dimensions and weight of the suitcase itself. The optimal balance between these characteristics depends on the number of people for which the product is designed, as well as on the characteristics of the planned trips.

Conventionally, suitcases can be divided into 3 categories: small(up to 30 L), medium(up to 70 L), large(up to 100 L) and huge(over 100 L). The first option is well suited for those who are going to travel alone, and the duration of trips is not very long. Also in this category are children's suitcases, which are distinguished by a catchy design, compact size and special appearance. Medium models are suitable for two people (or, again, for one — with a long journey). And the largest suitcases can be called "family".

Also note that some models may have adjustable dimensions and, accordingly, adjust to the volume; for such suitcases, the maximum volume is indicated in the characteristics — in a fully unfolded state.

Dimensions of the suitcase in height, width and depth (it is assumed that the product stands vertically on wheels). For products with volume adjustment, the unfolded dimensions are usually indicated.

It is worth noting that with the same volume, different models may have different sizes; knowing these numbers, you can to some extent evaluate the features of the suitcase and choose the necessary model of hand luggage on the plane. For example, a large width provides stability when transported on wheels, but is not very convenient when transported on a train — the suitcase may not “fit” under the shelf on the side; wide bags (see "Type") are also less convenient to carry by the handle on the front side, etc.

The weight of the empty suitcase. The lower this value, the easier it will be to transport luggage (with the same weight of things placed inside). On the other hand, lightweight suitcases usually have a less dense body material. Therefore, it is worth choosing a model by weight, taking into account what balance between strength and lightness will be optimal for you.

Internal pockets allow you to sort small things from the general luggage. Mostly made with mesh, which additionally allows you to see what is in your pocket and quickly get access to the necessary "little things".

— Fabric. Most often, in suitcases, this term refers to various synthetic materials, in particular nylon or polyester. Depending on the density (see below), the properties of the fabric can vary significantly — from a soft, easily crushed shell that provides virtually no protection from impacts to a dense and thick “armor” comparable in protection to thin plastic (although for particularly fragile items, it is still better to use products made of hard materials). In any case, the fabric is quite inexpensive, often has a waterproof coating, and sometimes other special “features” — for example, the Rip-Stop system, which prevents the hole from getting bigger in the event of a rupture. It is also much easier to provide additional pockets (especially external ones) in the design of such suitcases than in plastic( ABS plastic, polycarbonate, polypropylene) or metal ones. Due to this, the fabric has become widespread.

— Plastic. Plastic is lightweight and inexpensive; however, due to its hardness, it protects fragile contents from various impacts and loads much better than fabric. However, the strength of this material can vary — there are many types of plastic that differ in characteristics and, accordingly, price. So, ABS plastic is hard due to its heavy weight, but u...nreliable. It can crack under a strong impact and is unsuitable for subzero temperatures. Emptiness when filled is critical and can lead to deformation under load. But ABS plastic is the cheapest and brightest (any colors and patterns are available). Polycarbonate is resistant to ultraviolet radiation, has increased strength, impact resistance and heat resistance. It is a kind of middle link among plastic models. And polypropylene, which rises above other types of plastic due to its resistance to mechanical damage. It is practically not subject to corrosion cracking, impact resistant. And its flexibility allows it to be used not fully loaded and even empty. After all, if polypropylene bends under the weight of another suitcase, it will restore its shape on its own.

— Metal. Metal gives the suitcase a solid appearance, while it combines hardness with high strength, significantly surpassing plastic in both of these characteristics — metal suitcases are considered the most protected. At the same time, the cost of this material is quite high, the weight is also significant, and the mentioned level of protection is not always required — for most travelers, the capabilities provided by lighter and cheaper plastic products are enough. In this regard, this option has not become widespread.

— Leather. Genuine leather can be considered a premium material. It provides a rich and “presentable” appearance, and costs accordingly — so owning a leather suitcase quite clearly confirms the owner’s status. On the other hand, such models are quite heavy and require quite a lot of care — otherwise, all respectability will be hidden behind cracks and scuffs. So, from a practical point of view, leather is noticeably inferior to fabric and plastic.

Compliance of the lock installed in the suitcase (see above) with the TSA standard. TSA is an acronym for Transportation Security Administration, i.e. United States Transportation Safety Administration; it was at the suggestion of this structure that similar castles appeared — after the September 11 attacks. These events led to increased security measures during customs inspection, including more frequent opening of luggage — but without an owner with a key, the lock often had to be broken, rendering the product unusable and causing indignation of passengers.

To remedy the situation, TSA locks were developed. They may differ in design and appearance, be built-in, mounted, etc.; however, all options have two ways of opening and closing — normal and service. The usual one involves the use of a digital code — this is how the owner of the suitcase works with the lock. To open the "service" way, a special key is used that is compatible with all TSA locks; only customs and security officials have such keys. Thanks to this, if necessary, experts can easily and quickly open the suitcase for inspection, and then return it to the owner with a closed and fully functional lock. Some models of locks have an indicator that indicates that it was opened with a service key.

TSA keys are currently used by US, Canadian, UK, and Israeli Customs. So suitcases with such locks are definitely recommended for traveling to these countries; in addit...ion, the list can expand, so before traveling it makes sense to clarify the features of customs inspection at the destination. Do not neglect this nuance: if they decide to inspect your luggage at the entrance, this will be done anyway, and it depends only on the type of lock whether it will be opened with a service key or brute-forced without the possibility of repair.

The presence of a side handle on the suitcase, which allows you to carry it not in a vertical, but in a horizontal position. This solution appropriately facilitates the transportation of the suitcase, for example, on stairs, on uneven roads (earth, gravel, sand), etc.
