A must for bikers

This device is great. I ride a motorcycle and as suffering once before the battery. I opted for the simple fermentation for this product, because it is of Black & Decker and the name stands for quality for me. That you could tell when you've unpacked the unit. The material is processed stable and excellent. One has the choice between 6V + 12V with a simple switch. Attach contacts and that's it.
I recommend it all the bikers.
