Thank You very much for Your answer, all I need is to charge My cell, and batteries for My GPS, I will look for a proper inverter, for now I have a eliminator power box 400w, I didn't notice that it says "inverter" on it
I use it as a self rescue unit when I am in remote areas, to boost My car battery, charge My cell or other necessities, But is always in My car, will be more convenient to buy an inverter to have in My trailer.
