Bests & Worsts Reviews from Amazon

Bought this for son to charge his 120 watt laptop in the car, but it can't even The fan is very quiet, the cord is nearly 3 feet long which is sufficient, seems to be sturdy construction, but it can't charge my particular laptop. Update: Manufacturer contacted me to find out what model computer I was trying to charge. They then purchased a computer just like it and did some testing on their own. Turns out this computer runs on 19 volt and not 12 volt. I highly respect these guys for going through the trouble that they did in order to get to the bottom of my issue. Great Customer Service! So, in short, the problem was on my end. NOT the manufacturers! This product DOES charge laptops, just not some of the more powerful ones like my sons. I just didn't know any better, I was focused on wattage requirements and didn't understand the voltage requirements.
