Review: Stable power - When I moved from America to Thailand my computer (not laptop) came with me. In America there is 110 power source. Here in Thailand there is only 220 power. This does not matter when charging your cell or tablet but it does when you are talking about a computer. I got what they called a converter from 220 to 110 but did not work that well. The computer would cut off at times seemed for no reason. I got this stepdown transformer and this is the best thing I could have gotten. 110 power is perfect and computer never cuts off. If you need 110 power this is the way to go.
