Query: Cheap and breakable

I bought two of these so I could easily move my slim PS2 around the house without hassling with wires and power bricks, etc. They work as advertised--for about two months. Here it is April, and both of the units I bought in December have now failed. The playstation will turn off after between 1 and 60 seconds. I've heard that the laser in the PS2 is very sensitive to voltage variations. I don't know if that's the problem here; I just know that switching to the original Sony power supply cured all my problems. These units feel cheap in comparison to the ones from Sony. The Sony power brick easily weighs 2 or three times more than these flimsy things. Don't be fooled. These are NOT the same as the Sony units, and you should avoid them!
