    Very Happy With This Inverter: I received this Inverter and Installed it into my work van to run (2) 20 volt battery chargers, and also to use (3) of the USB outlets. Having used a couple of different brands of 400 Watt inverters, I was very happy to see that this did not get hot under the same power conditions of the previous 400 Watt inverters. It is made very well, and even though it’s early, it comes with a full 18 month warranty and I am very happy with this Inverter, it’s made of good quality, and runs very well…
