I went from a LG Envy3 to the Droid and have noticed that the Charger & cable look the same (charger puts out the same voltage). It is also two seperate peices like the Droid factory cable basicly a power supply and a cable with a USB end that plugs into the power supply. The end that plugs into the Droid has a letter B on it and the USB mark. Could I use that cablr & or charger on my Droid?
