Has anyone tried using an external USB power supply? I have a number of blue tooth devices (headset, cell phone, etc.) that I charge either from my computer or through an external USB power supply that plugs into a wall outlet or my car's cigarette lighter.
The connection is the same, USB mini. I'm certainly not an electrician but isn't there a de facto standard for USB devices. If I power my Procyan using a USB power adapter, could this cause damage or void my warranty?
