I just got my Nexus 4 and am wondering if I can use my Seidio car adapter I had for my old phone. I know the Nexus 4 is rated 5v 1.2a on the travel charger. The seidio car adapter is rated 5.3v +/-.3 and 1a. So I would think this would be fine. I just want to make sure the 5.3v is not going to be a problem.
