The Switronix 6' GoPro Regulator Cable allows you to power your GoPro Hero 3/3+ camera via a cigarette lighter whether in a vehicle or otherwise. The cable will convert the available 12v power to the proper operable voltage for the GoPro camera. The adapter locks into the battery receptacle on the back of the camera, so you no longer need to rely on the USB connection on the side of the camera which can come out easily.
Providing a reliable and secure power connection is essential when using the camera, since the GoPro's are often put in precarious, high impact situations. The adapter also allows the use of the front submersible housing of the GoPro and the skeleton back. Covering the back skeleton housing openings with some gaffer tape would prove to offer a splash/water resistant housing for many situations. The cable is offered in a 6' length which should provide plenty of length when mounted in or around a car and most other situations.
