Comparison Xiaomi 90 Seven-Bar Business Suitcase 24 vs Wenger Emme 68

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.

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 noticeably - from a soft, easily wrinkled shell, which provides practically no protection from impacts, to dense and thick “armor”, comparable in degree of protection to thin plastic (although for particularly fragile things, all It is equally better to use products made from solid materials). In any case, the fabric is quite inexpensive, often has a water-resistant impregnation, and sometimes other special “chips” - for example, the Rip-Stop system, which, in the event of a tear, prevents the hole from enlarging. Also, in the design of such suitcases it is much easier to provide additional pockets (especially external ones) than in plastic( ABS plastic, polycarbonate, polypropylene) or metal ones. Due to this, the fabric became widespread.

- Plastic. Plastic is light weight and low cost; at the same time, due to its hardness, it protects fragile contents much better from various impacts and loads than fabric. True, 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 i...ts heavy weight, but unreliable. It may crack if hit hard and is not suitable for sub-zero temperatures. The void during filling is critical and can lead to deformation under load. But ABS plastic is the cheapest and brightest (available in any colors and patterns). Polycarbonate is characterized by UV resistance, increased strength, impact resistance and heat resistance. It is like an average 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 and is impact resistant. And its flexibility allows it to be used not fully loaded and even empty. After all, having sagged under the weight of another suitcase, polypropylene will self-restore its shape.

- 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 degree of protection is not always required - for most travelers, the possibilities provided by lighter and cheaper plastic products are sufficient. Therefore, this option is not widely used.

- Leather. Genuine leather can be classified as premium materials. It provides a rich and “presentable” appearance, and at the same time costs accordingly - so owning a leather suitcase quite clearly confirms the status of the owner. On the other hand, such models are distinguished by significant weight and require rather troublesome maintenance - otherwise all respectability will be hidden behind cracks and abrasions. 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.
