Best alternatives to Tagus
If you're looking for the best alternatives to the Tagus , we recommend these models that can compete in terms of quality, features, and the number of books available:
Kobo eReaders
No products found.
The Canadian company Kobo , owned by Rakuten, is one of the best alternatives to the Tagus from La Casa del Libro, as it surpasses it in features and has an even larger bookstore, such as the Kobo Store:
Kindle
No products found.
On the other hand, another titan in the world of eReaders is Amazon's Kindle . It also boasts similar features to the Kobo, a competitive price, and the largest online bookstore, with over 1.5 million titles.
PocketBook eReader
No products found.
Another great alternative for its quality and features is the PocketBook . These products also have a multitude of available functions, the latest technology, and the PocketBook Store.
Characteristics of the Tagus of La Casa del Libro

To compare with the alternatives we have proposed in the previous section, you should also know some of the most outstanding technical characteristics of the Tagus:
Cover Lens
The Cover Lens is a protective film designed to shield the Tagus from bumps and scratches. This makes it less fragile than other eReader models that lack any kind of protection.
e-Ink Letter
E -ink, or electronic ink , is a widely used option for eReaders, as it offers an experience similar to reading on paper. These types of e-paper screens also consume significantly less battery power, thus improving battery life.
On the other hand, its operation is simple, with small white (positively charged) and black (negatively charged) particles trapped in microcapsules and submerged in a transparent liquid. In this way, by applying charges, the pigments can be controlled so that they display the text or image that is needed. Also, once they display the screen, they won't consume any more power until it needs to be refreshed, which is tremendous energy savings.
However, the Tagus's screens use the Carta variant , a very specific e-Ink technology that was first introduced in 2013 and is quite popular among current eReaders . This variant has a resolution of 768×1024 px, a 6″ size, and a pixel density of 212 ppi.
WiFi
Of course, the Tagus from La Casa del Libro has WiFi connectivity so you can connect to the online bookstore and thus buy and download all the titles you need without having to transfer them first to your PC and then via cable to your Tagus.
Android
It's based on the Android operating system, version 4.4 . This might seem a bit outdated, since mobile devices now run versions like Android 11 or 12. However, you don't need to worry, as this version is more than sufficient for the Tagus eReader's needs, although it's true that this version is no longer supported.
Bluetooth 5.0
On the other hand, you can also see that the Tagus Astro features Bluetooth wireless connectivity . Thanks to this, you can connect your wireless headphones or speakers to enjoy the audiobooks this model can play, so you don't have to read and can enjoy literature while doing other tasks.
ecoactive
Another notable feature of the Tagus is its eco-active design , which is important nowadays. This means it's designed for environmentally conscious consumers who want these technologies to be as sustainable and environmentally friendly as possible. For example, by using recycled materials, eliminating certain toxins, and being more energy efficient.
Kindle vs. Tagus
No products found.
If you're hesitating between a Kindle and a Tagus, we recommend a Kindle . It's a technically superior product with a library offering many more books and categories. Plus, you'll also benefit from all the advantages Amazon provides, such as Kindle Unlimited for unlimited reading with this subscription service, and Amazon's cloud storage for all your books.
In the case of the Tagus, Casa del Libro doesn't have as many titles available as Amazon, with around 700.000 titles compared to 1.500.000, and it also lacks services like Kindle. However, you can link your Tagus to a Dropbox account to upload your books.
It's true that Tagus from La Casa del Libro doesn't have ads or other interruptions to distract you from what you really need. But in the case of Kindle, there are also versions that, for a little more money, allow you to get rid of ads, and even slightly more expensive versions that also include Kindle Unlimited.
Finally, it's also important to remember that if you have Kindle books in proprietary formats like AZW3 or AZW , which are Amazon's own, they won't be compatible with your Tagus. This could also be a significant limitation.
Who makes the Tagus?

Casa del Libro doesn't have its own factory for electronic products. Therefore, they need an external company to manufacture them for them. This task fell to the Spanish firm bq , which, as you know, has disappeared.
The bq company was the one that delivered both the Tagus and the Inves eReaders of El Corte Ingles. In turn, this brand did not directly manufacture these devices either, they brought them from China and renamed them and customized the interface for these clients.
What formats does the Tagus read?
The eReader Tagus from La Casa del Libro are somewhat limited in terms of format compatibility, since they allow eBooks to be read only in EPUB or PDF formats. While the audiobooks it supports can be uploaded in both MP3 and WAV formats.
Other eReaders, as you can see on this page, support many other formats, so they will give you more compatibility possibilities without having to use Calibre to convert from one format to another.
How to transfer books to eBook Tagus?
To download eBooks or audiobooks from La Casa Del Libro to your Tagus, the steps to follow are:
- The first thing is to have a user account on the web casadellibro.com.
- The second thing will be to turn on your Tagus and press Start.
- Connect to WiFi and link your Tagus with the casadellibro.com username and password.
- You will now be able to Synchronize the library.
- All the titles you buy will be stored in your Tagus profile and will be ready to be accessed for reading.
Where to buy a Tagus?

Finally, if you want to buy a Tagus from La Casa del Libro, your options are somewhat limited, as you'll only find it available at:
El Corte Inglés
El Corte Inglés also includes Tagus eReaders among its electronic products. Therefore, it is an alternative store where you can find these Casa del Libro devices. In this Spanish chain you can order it through its official website or go to any of its sales centers to buy it in person.
The book house
Of course, La Casa del Libro also allows you to buy your own eReader, both from its website so that it can be sent to your home or if you go to any store of this bookstore chain. In addition, from there they can also advise you if you have any questions.
