This is 150 watt power inverter is great for emergencieseemergenc, or customizing your vehicle, you can even run a blender in your car! The casing is native quality material and it feels very sturdy. I use it to power my plug-in LED lights on my truck, and it rarely heats up, when it does it has a full built-in fan that kicks in. I love the fact that it has 23.1 a usb chargers as well!
