I'm using a 5V boost regulator?
to charge a cell phone battery. BUT maximum current is 200 mA. That's not enough current I'm assuming, right? I need a continuous output of 5V but my students are most likely not going to get 5V from a shake charger (neodymium magnets going in and out through a coil of wire) which is why I was going to use a LM7805 but that needs 3 volts more than the output voltage. Any suggestions?? Thank you!
