Works Great!

The Poweradd 300 Power Inverter is Great ! It has a built in fan to keep from overheating, yet it is extremely quiet. I can't even tell that it is on, unless I put my ear right up to it. The cord is long enough to reach both the passenger's side and driver's side of our truck. It does not get hot, even when it has been in use for more than 2 hours. The inverter has enough power for my cellphone and laptop. I have not tried anything else with it yet, but I am betting that it will power exactly what the company claims that it will. It appears to be very well made. The cord is heavy duty and the unit itself is made of metal. There are USB outlets, as well as the wall outlet. I think this is a great item and a very good value. I would definately buy it again!
