yes this and most usb chargers that plug into the 12v only do 5watts (5v@1amp) as the usb is set as data, which will cause them not to charge as fast (or slowly drain under full load.) Pretty much your phone sees it as a usb instead of a wall charger.

I bought this one from Amazon and the one reviewer even mentions how he cracked it open to solder it so he can get full 2amps out of I just like it for its small profile and dual usb.

spiderpig So from the sunday-monday ride - 12v was able to keep my phone charged at 100% all the time. So it's all good.

spiderpig Ok will test today on the drive and let you guys know.

Now534 It might be a 2000mA plug splitting out 1000mA each. And it lights up blue inside the ports.

Now534 Usb output is more than likely 500mA. On my android I'm using a 3000mA dual Usb charger. It splits to 1500mA per connection. I got mine from bestbuy

emsvitil Get a high amp output 12v to 5v usb converter (minimum 1 amp) and try that.

The built in usb may not supply enough output amps.

goinloco1 best bet is to get a stand alone gps such as a garmin nuvi. they aren't all that expensive.
gps apps on phones are notorious resource hogs, both power (i.e. processor) and memory.
If you must use it and listen to music, use 12v and stream music via bluetooth. It can keep up with charging that way (if you have sync its easy to stream through bluetooth, you don't need usb)
