Why should it? If the FR can charge at 3 different rates (100, 500,  
1000mA), any charger that can give 500 or 1000mA is good enough... it  
all depends on how much time you want to wait for a charge... ;)

I tested it right now, and it does charge. The problem is that this  
"Trust" car cigarette lighter USB charger does not have the "ID pin"  
resistor [1].
Even when using a standard USB-to-miniUSB cable the FR recognizes the  
charger as a 100mA "host" port (and charges at 100mA, which is not  
good enough).
So I used the sysfs entries in [2] to force it to 500mA and 1000mA and  
all went well - it can charge just fine, but has to be forced because  
there is no auto detection.
So now I just install the usb charging control scripts in [2]... :)


Happy hacking!
