Type
— Protective case. This type of security is found mostly in tablets and is almost never used in e-readers. By design, it is the simplest type of cases, covers only the back wall of the device and the ends, protecting them from bumps and scratches; the screen remains open. Thanks to this, you can safely put the tablet on hard surfaces — not the back cover will be scratched, but the cover covering it. At the same time, protective covers are poorly suited for transportation, because. do not protect the screen and may require a screen protector. Their main purpose is daily use within the same premises (home, office, etc.). This type of cases is not universal (see "Compatibility") and is always made for a specific tablet model, because. for successful use, it must exactly match not only the diagonal of the screen, but also other dimensions of the device, as well as the shape of its case. Accordingly, protective covers for different tablet models are usually not interchangeable.
— Cover. In full accordance with the name, these covers resemble the design of a book cover. At the same time, a tablet or an e-book is fixed motionless on one of the halves, the second one covers the screen. This design provides maximum versatility: when unfolded, it is similar in purpose to a protective cover (see above), and when folded, it provides good security during transportation, because. covers both the back of the device and the display. Also, the design may provide transformation int...o a stand (see below). Covers can be both specialized and universal (see "Compatibility"), they are found among tablets and are very common among readers, because. make it look like a real book.
— Flip. Like the protective case (see above), this type is found mainly in tablets and covers the device on one side only. However, it looks more like a cover (see above): usually the flip is attached to the tablet from the side or back and is made folding. Thus, during transportation, it covers the screen of the device, and in everyday use, you can flip the flip to the other side, so that you can safely put the tablet with the back cover on hard surfaces. Often this type can be transformed into a stand (see below for more details). Flips are almost never universal and are usually made for specific tablet models (see "Compatibility").
— A bag. A variety of covers designed to be used primarily when transporting a tablet or e-reader. In working condition, such a case covers the device from all sides (or leaves only one end open), and to use the gadget, you need to remove it. However there are exceptions — some models are made transparent, which allows you not to remove the device from the case — but they are quite rare. Bags more often than other types are equipped with additional devices for ease of carrying, such as a handle or a shoulder strap (see below for more details). It is also the most versatile type of case: usually the only determining factor for bags is the screen size (see above), and even specialized options (see "Compatibility") can be designed for not one, but several models at once.
— Keyboard Case. Almost all such models are designed for tablets and, in accordance with the name, combine the functionality of a protective case and a portable keyboard. Usually they have a design similar to the covers (see above) — a tablet is attached to one of the halves, the keyboard is located on the second. Almost all covers of this type have the ability to transform into a stand (see below), which allows you to actually turn the tablet into a netbook. The keyboard connection can be either wired (USB) or wireless (Bluetooth); in addition, in some models it can be made removable, and if necessary, the cover can be turned into a regular cover. The disadvantage of this type is the high price due to the presence of the actual keyboard.
Clasp
— Magnet. Clasp based on the action of a strong permanent magnet. When it is closed, the magnet “sticks” to a special metal element on the other half of the cover, or, in the case of flips (see “Type”), to the body of the tablet. The main advantages of such a fastener are simplicity of design and durability: the magnet practically does not wear out, does not lose efficiency over time, and does not suffer from frequent opening/closing. As a disadvantage, one can name a relatively weak fixation; however, magnetic fasteners are usually designed to minimize this disadvantage and are reliable enough for most applications. Thanks to this, the magnet is one of the most popular types of fasteners. At the same time, we note that when using covers with such clasps, you need to exercise some caution: they should not be placed next to credit or other magnetic cards, because a magnet may render such a card unusable.
— Hook-and-loop. The Hook-and-loop fastener consists of two surfaces: on one there is a layer of felt, on the other — microscopic hooks that catch on the felt fibers when the surfaces come into contact. This provides a fairly strong grip. The disadvantage of Hook-and-loop is increased wear with frequent use, because. with each opening, part of the fibers breaks out with hooks. Therefore, such fasteners are rather poorly distributed; they are mainly used in bags (see "Type"), where opening and closing the clasp is relatively infrequent.
— Elastic. Elasti...c fastening that holds the two halves of the case together. Due to its design features, it is used exclusively in covers (see "Type"), but among this type of covers it is only slightly less common than a magnet (see above). The fact is that the rubber band combines simplicity and reliability of holding, while it does not pose a danger to magnetic cards. Among the shortcomings, one can name a tendency to stretch with inaccurate use (due to which efficiency is lost), and in general, somewhat less durability than a magnet.
— Rivet. Another popular name is "button". By design, such a clasp is similar to a regular button used in clothes: on one half of it there is a curly protrusion, on the other — a recess with a special lock. When closed, the protrusion fits into the recess and locks into place, ensuring a secure fit. Actually, the reliability of retention is the main advantage of rivets. On the other hand, they may require considerable force to open and close. This, firstly, is not very convenient, and secondly, it wears out the material around the button a lot — up to loosening and falling out of the fastener with a relatively intact case. This puts forward separate requirements for the strength of the case itself. Because of all this, rivet fasteners are quite rare.
— Lightning. The zipper is used exclusively in bags (see "Type"), and more often than any other type of fastener. This is the best option given the main purpose of bags: zippers close and open easily and quickly, are quite durable and even provide some degree of additional protection at the ends.
— No zipper. Fasteners, by definition, do not have protective covers (see "Type"); also, models without fasteners are often found in bags that leave one end of the device open and are designed for the fastest access to a tablet or e-book. In other types, this option is quite rare. Also in this category are bags with a drawstring that tightens the inlet neck.
Carrying handle
The case has a special handle for easy carrying in the hand, in the manner of a regular bag. Actually, this function is found mainly in cases-bags, and also, occasionally, in covers (see "Type"). Carrying handles can be supplemented with special pockets or other devices that allow you to hide them until they are needed; this provides additional convenience and gives the case a neater appearance.
Auto on/off
With this function, the case actually turns into a control device for a tablet or e-book: when the screen is closed, the gadget is automatically put into sleep mode, when opened, it goes into working mode. This eliminates the need for the user to turn the device off/on manually every time, and also provides significant energy savings. This function is found only in specialized cases (see "Compatibility"), and the specialization must be extremely accurate — even similar models from the same manufacturer may not work correctly in such a case.
