I would suggest avoiding chargers supplied by/for some phone manufacturers as well. One friend of mine fried his Kindle when they used the fast charger for his phone. Evidently, a USB-C plug does not mean guaranteed compliance with the USB-C Power Delivery specification. His old Android phone charger started at 9V though whether that was a issue with the Qualcomm quick charge technology, the hardware implementation of the charger (not sure if it was a Xiaomi supplied charger or a third party charger) or the hardware implementation in the Kindle was not clear.
