How many Amps on the RHR USB port?
 
How many Amps does the USB port on the RHR output? I've noticed that when I'm running any apps on my phone that even with my phone charging off the USB on the NAVI that the battery percentage keeps on decreasing.

I bought a charger that plugs into the cigarette lighter that seems to do the trick now although kind of a waste of a good USB port if it can't keep up.

Re: How many Amps on the RHR USB port?
 
I assume the USB port complies with the standards. From an article

In terms of current capability, the USB 2.0 specification calls for 1 to 5 unit loads as the maximum capability of a USB port. One unit load is defined as 100mA, and whether the port can supply one or five unit loads depends on the port type. Low-power (100mA) ports are hub-based USB ports, whereas high-power (500mA) ports are host-based USB ports.


Today's higher-current devices (phones, tablets, etc) draw more current in operation than a 500ma source can provide.
