There are many, none of the iPhone so called universal USB chargers will work.
They us a iPhone protocol and limit the output regardless of the rating.
You need a 1 Amp charger for non-iphones.
I use the "GTMax Metalic Silver 2-Port USB Car Charger Adapter", just plug that in Amazon. Should be under $10 and comes in several colors.
One side is iPhone protocol and one side is non-iPhone.
Charges even while I have everything running, Navigator, Phone, Radio App and on a road trip for hours with screen lit the whole time.
I use the other side to charge my backup hands free. Even though its marked 2.1 Amps it will not provided that charge for an android.
The two data pins are shorted in the charger for non iPhone chargers and not for iPhones. Many generics use the iPhone protocol and say they are universal, they are not.
Use the 1.0 Amp non-iPhone side and it will work great.
Don't like that one, check the write ups. Look for one at 1.0 Amp and not for an iPhone.
