Bonjour,
pour un projet, j'aurais besoin de communiqué avec une powerbank, pour configurer la sortie du cable USB A 3.0 en une sortie 10V, et non pas 5V comme par défaut.
Je n'ai trouvé aucune documentation sur internet avec des projets qui auraient déjà fait ça.
L'avez vous déjà vu ? Est-ce que ça vous semble faisable ? Avez vous des liens d'aide ?
Merci d'avance
Some sort of boost converter?
It will boost the voltage, but the power will remain the same. (Well, slightly less)
Not exactly.
I have a xiaomi powerbank 20000, which can provide several different power.
By default it provides 5v 3A, but I would need 10V 2.25A (it can provide it).
Normaly, you have to communicate with the battery (via the USB data cables) to ask it to provide a higher voltage than the basic one.
The problem is that I didn't see anyone doing it on the internet, and the USB protocol is too complex for me to develop this communication in a complete way
Is that a one-time action? Or do you have to repeat it each time that you connect it to USB?
Is there a PC application that allows you to do that configuration? If yes and it's a one-time action, hook it up to a PC and configure it.
A link to the user manual of the Xiami 20000 can be useful.
C'est -à-dire, il y a de l'USB type C?
Bonjour alk1426
Tu peux mettre un module de ce type à la sortie USB A 3.0:
