I recently got a HTC Incredible and was wanting a charger to use while at work. I found an old SIRIUS AU505D wall charger for the S50 unit that has a USB port where I can plug in a micro USB cable. The output on it is 5.0V 1A just like the HTC Incredible wall charger. So at face value all looks good.
I have two other options, a Travel Charger 300535 micro USB charger with 5.0V 750mA output for a RAZR2, or I could just use micro USB cable plugged into my work laptop while I am at work.
Is there anything else I should be worried about internally (safety devices?) before using the SIRIUS charger even though it has the same output as the HTC Incredible charger?
