A software product that ensures the correct operation of the installed software and convenient management of e-book functions. Conventionally, the family of "readers" is divided into two large camps: some work under the Android OS (in various versions of
Android 6.0,
Android 9.0,
Android 10,
Android 11,
Android 12), others run Linux. The Android system is not always well adapted to the features of the e-book interface, but a significant trump card up its sleeve is support for installing applications from the Google store.
Linux -led readers stay afloat longer in offline mode, but most of them cannot be installed with third-party applications.

— microUSB. Connector for direct connection of the reader to the USB port of the computer using a special cable. In e-books, this connection is used primarily for file sharing. MicroUSB is a universal standard that allows you to connect various gadgets through it with one cable.
— miniUSB. Similar to the one described above, the connector, which differs only in the size and shape of the connector.

USB-C. Symmetrical USB connector, which is gaining popularity and in the future is able to displace microUSB. At the same time, the connector has a high data transfer rate and is only a little larger in size.
The presence
of a case in the delivery set of the electronic reader.
The case facilitates transportation of the device, protects its body from dirt and scratches, and to some extent protects from impacts and vibrations. The design of such an accessory can be different. One of the popular implementations is the "book" format (the case opens in the image and likeness of a book cover), cases exclusively for the back panel of the e-reader are also often found.
