I just got a blackberry Curve 9330 from my work, and I also have a Original Moto Droid, and 2x plantronics 925 headset's that I use with both phones. All 3 devices use MicroUSB chargers, however each charger has a slightly different mA rating output. Blackberry Curve - 5.1V 850mA Moto Droid - 5.1V 750mA Plantronics Headset - 5.0V 350mA I'm wondering if its safe to use the different chargers with the different devices? At least for the blackberry and droid, can I use the other phones charger without problems from under powering? or powering? As for the headset, I have tried to charge my droid with it and it seems to get nothing, I assume its not enough power. But I would still wonder if I can charge the headest using the blackberry or droid charger without any issues. All the chargers I have are the original Manufacture charger that comes with the new device.
