I've been a big fan of these cables, charging performance seems fine: http://www.amazon.com/gp/product/B00FAADBHO/ref=wms_ohs_product?ie=UTF8&psc=1

Cloth wrapped and sturdy as heck.

Also this has a 1A and 2.1A socket plug and 2 of the traditional lighter plugs. http://www.amazon.com/gp/product/B003RQBKLC/ref=wms_ohs_product?ie=UTF8&psc=1 It charges my wife's iPad so I know it's putting out at least 1.8A out of the 2.1 socket. I can run GPS/Soundcloud and it will charge my N5 pretty quickly.
