I bought this hoping to power some low wattage lights and other low power equipment only to find that it does not even have a polarized plug! Who the heck puts a three prong grounded outlet on anything with a plug that is not polarized. I wish I had never purchased this item as almost all of my equipment has polarized plugs. I ended up going to the local electronics store and looking for one and sure enough there was not an inverter in the store that did not have a polarized outlet on it. I hope I can save a few others from making the same mistake I did by posting this review!

It does not have a polarized plug, it gets warm when working, and it is not 240 watts unless you count all the heat it puts out, and I would not recommend using it unless you are close by just in case it catches on fire.

I do use it with several new and old devices with non polarized plugs such as my AC cell phone chargers, my 50 year old lamp, and hard wired to many AC devices in my lab.

I am happy with my purchase, and 2 years later it still works and has never set anything on fire yet, but I paid $16 with free shipping in 2010, and it's not worth much more.
