This actually works as described. Would highly recommend!
This device provides stronger engine starts and extended battery life , it is great for my older car, it is very convenient to have so when necessary there is not need to ask friends for help, or even worry about being in trouble far away from help, with this I feel much safer on the road!
This charger is a perfect maintainer for batteries in vehicles that aren't driven a lot.
Its easy to use and connect , if charge is needed the charge led blinks ,once battery is fully charged you have a steady light .
The price was also really good for its value.
