Not at all for charging, my truck is older and did not have ability to play music through them, that was added in 2010. When we're all in the truck, there's just too much junk to keep charged up! So the dual adapters that charge at 2.4A and 2.5A for both ports in the adapter works better for us. Bought a cell phone holder that fits in the cupholder that has cigar lighter sockets and USB ports too and it plugs into one of the truck's cigar lighters now on the dash. Plus I have a dash cam that is not permanently wired either.
