My Lenovo Yoga book takes 5 or 12 v A amp trough usb micro..anyone has an idea how i can make an usb C charger for this that charges via 12V usb c? If its a cable or something that's fine, I just wanna use the usb PD powerbank i have to charge the tablet.

boosting this to #engineering in the hope someone can help me with this issue because this is beyond my skillset, trough when i have a handle i can build the PCB and everything myself. I just don't know where to start with documentation or anything.

@tretron Only USB C plugs allow higher voltages than 5V...so, did you mean that?
USB PD (power delivery) includes a protocol that negotiates power between the upstream and downstream device. That happens on pins that a USB C connector has, but that the micro-USB connector lacks. So if you want 12V, you need USB C.

@PKL yes I want to convert the USB C PD to 12V micro usb. This tablet has what many equiptment i have from the time, while they charge with 5V, its not enough to run and charge them and such. So this tablet has an strange non standard way to charge it with 12V 2A via usb micro. but I have no idea how it works. I lost the charger which it comes with, I can buy one but that still leaves me with the want to have it charge from powerbanks and such.

@tretron oh that sounds super sketch and very much above my pay grade. :P What happens if you plug this "special" 12V charger into a regular USB micro device? 🔥 ?
