Is particularly satisfied with the replacement of several chargers with a single home RavPower RP-UC11 model i wanted the same accessory for charging batteries used dappareils in my vehicle. My choice sest fixed on a Dual USB Car charger 24W RP-CC02 model of the same designer. While the number dappareils used in my car is less important than those used in my home but I'm not looking for the adapter corresponding to each of my devices. Thanks to the iSmart technology that automatically dadapter the electrical load connected to the device according regardless dune possible overload. I tried without any difficulty devices each having a different USB connection (Iphone, GPS, handsfree and an external battery).
