My point is that it is NOT necessarily that simple. That even if the charger is rated to provide adequate current, the phone may not accept its maximum current draw. If the current flow rates I observed remained consistent throughout the charge process, the DX and Bionic would charge about 13% slower on the HTC charger (assuming the entire current is used for charging the battery). Probably not a significant problem for most people but for power users that may rely on small bump charges on their drive to work/home to get them through the day, it might be critical. Could be even more important for people who use battery intensive applications while driving/charging. If the running apps draw 500mA then that may only leave 250mA available to charge the battery. 100mA less than that is a 40% difference. That would probably be significant to a lot more people...
All but one of my chargers are labelled with their output amperage, so I can choose either a more powerful one or not. The bionic charger is rated at 850 ma. My MiFi charger is 1.05 A. I have another that isn't rated, but it works. I have others that aren't handy at the moment for me to check their output, but they all work. Plugging into my PC is almost a waste of time as the USB output isn't enough to keep up with the phone's current requirements.
