So, like... I am a science teacher and I have the concern that the voltage is not quite what the phone expects. The phone wants 12V and is getting 9V. I know we are taking emergencies, so even if you fry your phone, it is probably worth it to save a life.But I want to know, IS THERE A BIG DEAL with the input being 9v verses the 12V it would want to have? Will the electronics inside the phone regulate the voltage?
Due to this being outdoors, I would recommend using SPAR urethane which is rated for just that. I have gotten even paper mache' to resist rain with SPAR. Anyone at the store can point it out to you.
