    After camping for a couple of days, I thought about a solar charger for my phone. I have a 2.4W 12v solar charger/maintainer. If I run it through a 7805 will I actually be able to get 480 mA (best) output?

    The phone wall wart has an output of 800 mA.

    Thanks!

    I think you can get 200 mA. Solar charger you have should work fine. It will simply take longer to charge the phone.

    I agree the 12v output is 200 mA, but will the 5 volt output hit 480mA?

    I would use a 12v charger made to plug into a cigarette lighter. It's designed for 12v in, and has the regulation already built into it.
