I bought this for charging my Motorola RAZR while at work and it does not work. I plug it in and the phone registers that the charger is attached but hours later my phone is still not charged. When I use the charger that came with my phone it charges the phone in less than two hours so I know there is something wrong with this one. I personally am very unhappy with this purchase and cannot recommend it.UPDATE: I ordered a travel charger directly from my cell phone company and, while it looks exactly like the one I ordered via Amazon, it performs 100% better - it charges my phone in about 90 minutes. So I now know for sure that this one is defective. 85 cents might sound appealing, but if it ends up in the landfill then it's nothing but junk.
