Well I have wired the sat nav in and placed the USB wire by the head stock. The sat nav is wired to the battery at the mo. Can anyone tell me what the USB will output? I assume 12V as its on the battery but does it step down? If not is it still safe to charge an iPhone on it?
USB output is 5 Volts of Direct current, the standards define the current available, however this is normally disregarded and 500mA is where it starts with most phones needing 2000mA (or 2 amps). No one talks about the voltage, just the current.
I would assume it`s 5V like all USB. 3. A powered USB Port is included with the motorcycle power cradle. This provides a new way to keep your phone or music player charged while riding your motorcycle. 7 Things You Should Know About the New Zumo 590LM - Touratech-USA Google is your friend
