I have a 7.2V power source which I use for my very powerful mountain-bike front light. Now I am wondering whether I can attach a USB-C cable to it and charge my Samsung Note phone as well (USB-C, PowerDelivery-enabled). Is that the perfect way to fry a $1000 phone, or does it make any sense? You are welcome to bash/shred me for my ignorance, I don't mind...
