Essentially this is the deal. If any of you got the new motorola phones you know they now are using the Mini-USB port as the charging port. I have a Motorola V325 and my work bought me a Motorola 8703e Blackberry. I also have the Bluetooth H500 earpeice for the blackberry. All three devices use the exact same mini-USB port. However, the blackberry's charger says on it 5V 0.75A while the V325 and the bluetooth earpiece charger both say 5V 550mA. Essentially I'm kind of scared that one day I might accidently plug the wrong charger into the wrong phone. I would think a company like motorola would make their phone chargers so that they can't be mismatched with each other. I don't know much about how the phone charging devices work so essentially my question is if I plug my 5V 0.75A charger into my bluetooth will it damage it or will it just use enough Amperage (like a car battery ) to charge it. I found that if I plug the lower amperage charger into the blackberry for some reason it still charges. Any comments.
