Better USB Charging

I have a 2011 SL, and the USB port is nearly useless for charging a contemporary cell phone--not nearly enough mA output. Likewise with the cigarette lighter port.
I assume this has been remedied in the later models, but has anybody successfully managed to overcome this limitation on the older ones? Would it be very difficult to pass a wire from elsewhere to power a USB port?

The "lighter" port should have enough power to charge a cell phone.

Correct, the cigarette lighter "should" be able to power a 20a+ 5v charger but of course you don't really see them much larger than 2.5a each and maybe a 3-4 port adapter. I personally use a dual 2a USB adapter and both my '12 and '13 power it just fine, but ya the built-in USB port is near useless for charging a modern cell phone.

I did just such a thing, now i have three USB ports with one over 2 amps. I don't really like how the little door sticks up when using the stock USB.

I have been using the multiple outlet adapter for years, and it has NO INSTALLATION. It plugs into the cigarette lighter, and you can use hook and loop pads to lay it on the little tray right below the power plug. It fits perfectly....

Oh shoot, folks, thanks for all the replies (and sorry I sort of left it hanging...)!
So it sounds like the bottleneck for charging the phones via the lighter port is the adapters I've been using--not the port itself!
So, yeah, I'll just buy a higher capacity one as suggested, and spurn the little built-in USB one--no biggie!
Cool... :)

The factory USB plug is really NOT for charging...

It is FANTASTIC to control your IPHONE or IPOD music or sound, with the information displaying on your radio display... I have a 160gb IPod permanently installed there, and have all the music I could want...

I removed the stock usb port and broke open a lighter adapter and replaced it with a dual 2.1/1Amp charge port
