This charger that plugs into the cigarette lighter socket is suitable for cell phones, tablets, MP3s or other devices with a micro USB. The 1.5m-long cable lets you power devices in the back of the car from the 12V power socket in the front. It has a distinct blue LED light that indicates when it is plugged in. You will also certainly appreciate the small size of the device, which is great especially for drivers of cars with the power socket very close to the driving controls so they don't have to deal with a large device. Operation safety is ensured by double protection against overloading and short circuit. Keep your phones or other devices always fully charged, even during a long drive.
