So long deteriorating battery! The Rock Smart charger is a truly intelligent charger, and the first of its kind in South Africa. It auto-disconnects when your phone is fully charged, thereby saving power, and, more importantly, prolonging the lifespan of your battery! It also prevents Lithium-Ion batteries from overheating and swelling, thereby extending overall battery lifetime and protects your phone in the process. Each cable is 1 meter long as is available in lightning or Micro USB. In addition to the abovementioned awesomeness, it features an elegant silicone outer and an intelligent LED indication ring. Please take note that the lightning cables are not yet MFI certified.
