I was reading a few tutorials on creating a portable charger which will charge my iPod on the go. How many volts does the iPod Touch take? I bought a solar charger which worked perfectly on my video but didn't work at all on the Touch because I don't think it has enough power. And I also don't wanna fry my iPod. Is it 5v? Thanks. Once I successfully make this, I would be sure to post a step by step tutorial for noobs here.
