I am aware that the FP3 is not compatible with every usb-c chargers, and so not mine. I am waiting for the official one, but in the meantime I would like to try the Nintendo Switch chargeur. It is an usb c with two output : 5V/1.5A and 15V/2.6A. I would like to know if it is safe to use it. I mean, there are two possible output and this charger is not fit for the FP3, so is it possible that it would give it the wrong tension ? Is the FP3 protected from this ?
