Using Moto Droid Car Charger with Samsung Galaxy Nexus I just upgraded my phone from the original Motorola Droid to the Galaxy Nexus. Both phones use the same micro USB port. Is there any reason I cannot use my Droid's car charger with the Nexus?
It should work fine -- Micro-USB is Micro-USB.  The only possible caveat is the phone and charger may not negotiate high speed charging.  However, that's unlikely.

My wife and I have shared wall and car chargers between her old Droid, current Droid X, and my Incredible without any problems.
