I bought this item to use in one of our work trucks because we have equipment that requires cigarette lighter adapters. There are times when we need to use two or more at one time, not including a phone charger. The three ports along with the USB ports allow us to plug in everything we need at one time. The quality of this product seems to be very well made. It has been in the work truck about a week now and works perfectly. I plan on buyiing another one for our second work truck as well.
