Review on 3 Socket Cigarette Lighter Splitter SUPERONE by Mike Sutton

The thing is perfect. You can check your voltage when the key is in the start position to check the health of the battery, and then check it again after it's running to check the health of your alternator. My wife's generator had a malfunction and we realized immediately what it was as the voltage dropped intermittently during operation. I like that you can smoke out of it. You just have to pull it out beforehand. If you don't, it will get hot and shoot out of the advertised car after the plastic melts. Although it's probably my cigarette lighter. It has a cord and can reach. Highly recommended.
