You can convert a USB cable into a charging cable by shorting the data pins (on the device side), or you can buy charging only cables. I've been using these cables on my S2, and now my S5: . I used a Galaxy Charging app to verify charging rate and it indicated 1.2A on both the Samsung wall-wart and cable as well as my Scosche 2.1A car charger w/ charging only cable.
I also bought a charger (Rapid USB Car Charger, that was able to charge up to 2.1 A, but when I connect my Nexus 5 (with OEM cable), I charge with speed of 500 mA. I expected least 1 A.

I'm not amused at all! End users shouldn't have to deal with this nonsense. This should work out of the box!

I have two alternative:

1. Buy this charging cable.
2. Change kernel to trick the phone to draw more power from the USB port.

This 2A charger from PowerGen has dual ports that are actually labeled for Apple and "Standard" charging. PowerGen 2.4Amps / 12W Dual USB Car charger Designed for Apple and Android Devices

Works fine with the stock cable also. I have this one in my wife's vehicle since she has an iPhone and I have a Samsung.

I heard that cables matter the most in charging. I always use cables that came with my phone and have had no issues charging my phone so far. Have used PowerGen and Avantek. Both charge my iPhone 5 and Samsung Galaxy S4 at full speed. High quality construction and seems pretty durable.

This car charger works flawlessly at 1800mAh, i have been using it for a few month now.

I tried at least 5 different chargers and none of them charged more then 450mAh, i was really depressed about it until i found the charger linked above. Also, the fast charging USB cable *charges on 750 - 850 mAh which is just enough to not let your phone loose battery percentage while the navigation is turned on.
