Characteristics of the Tagus of La Casa del Libro

To compare with the alternatives that we have proposed in the previous section, you should also know some of the outstanding technical characteristics of the Tagus:

Cover Lens

La Cover Lens it is a kind of protective film to make the Tagus protected against bumps and scratches. In this way, it will not be as delicate as other eReader models that do not have any type of protection.

e-Ink Letter

La e-Ink, or electronic ink, is a widely used variant for eReaders, as it offers an experience similar to reading on paper. This type of e-paper screens also consume much less battery, so it will help improve autonomy.

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 screens are of the Letter variant, which is a very specific e-Ink technology that was first introduced in 2013 and is quite popular with today's eReaders. This variant has a resolution of 768×1024 px, 6″ in size, and a pixel density of 212 ppi.


Of course, the Tagus of La Casa del Libro has WiFi connectivity so you can connect to the online book store 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.


It is based on the Android operating system in its version 4.4. It may seem like a somewhat outdated version, since mobile devices already have versions like Android 11 or 12. However, you don't have to worry, since this version is more than enough for what this Tagus eReader needs, although it's fine. It is true that this version is no longer supported.

Bluetooth 5.0

On the other hand, you can also see that Tagus Astro has wireless BT connectivity. Thanks to this, you can connect your headphones or wireless speakers to enjoy the audiobooks that this model is capable of reproducing, so you don't have to read and can enjoy literature while you do other tasks.


Another remarkable feature of the Tagus is that it is a design ecoactive, something important today. In other words, designed for green consumers who want these technologies to be as sustainable as possible and respectful of the environment. For example, using recycled materials, eliminating certain toxins, being more energy efficient, etc.

Kindle vs. Tagus

If you are hesitating between Kindle or Tagus, the truth is that we recommend a Kindle, since you are going to have a technically superior product and also a bookstore with many more books and categories available. In addition, you also have all the advantages that Amazon offers, such as its Kindle Unlimited service to read without limits under this subscription service, or the Amazon cloud to store all your books there.

In the case of Tagus, La Casa del Libro does not have as many titles available as in the case of the Amazon store, since it has some 700.000 titles compared to 1.500.000, and it does not have services like the Kindle either. What you can do is pair your Tagus with a dropbox account that you have to upload your titles.

It is true that Tagus from La Casa del Libro It has no ads or other interruptions that distract you from what you really need. But in the case of the Kindle there are also versions that for a little more money you can get rid of the ads, even slightly more expensive versions that also include Kindle Unlimited.

And, finally, we must not forget that if you have book titles purchased on Kindle, with proprietary formats like AZW3 or AZW, Amazon owners, will not be compatible with your Tagus. This could also be a major limitation.

Who makes the Tagus?
