Hachette cubes in Italy

[n-harari]

Hello,
just wanted to let you know that these audiobooks were sold by Hachette in Italy as well:
https://figlimoderni.it/2020/01/audiofiabe-la-nuova-collana-di-hachette.html
The series was suspended though.
I have all the books and sd cards, however the audio box broke down (it won't charge anymore) and I am desperate to find a substitute. Any idea of what device I can use? It seems impossible to find the Hachette cube on Ebay or other websites, I tried looking for the Mexican, Spanish, German version at no avail.
Thanks for helping out a total newbie!

Hi
I can suggest you to use a power bank attached externally or change the battery inside.
@oyooyo The Italy version is the blu one, before find this repo, I managed by myself thought mifare classic app and an android phone to generate all the tag that I had missed and worked good. Now tanks to the software in this repo I had also the mp3 version to listen in every device.
