For most situations wireless charging is an option use a QI receiver just google it specific to the s5. I've purchase from amazon for my s3,4,note 3 and they work fine. The benefit of these are that it does not affect the physical dimensions so you able to use any case for the s5.
I have the samsung and a nokia purchased at verizon I find that the Nokia charges faster and tends to have better charging connectivity even with ruggedized cases, UAG, Trident, Otterbox, I'm a phone...well overall geek minus the pocket protector.
The beauty about the samsun is that it uses a micro usb so I have one mounted using velcro I purchased from walmart to use in my vehicle you obviously have to find a suitable location but I guess using the tradition cla in the car is much safer.
