OK, so, I have a phone and my power supply company has notified me that they are turning off the power for a few days to update the equipment. I want to charge my phone during this time but since the power will go off, the chargers in the outlet won't work. I've tried looking for 'wireless charging apps' (yeah, call me stupid but I did.) but they all tended to be prank apps or viruses according to the reviews so not much luck there. I've heard of wireless charging (the black circle that charges your phone) but, I'm not sure if it needs power to charge it. Help?
