It's a nice power supply: has a potentiometer that can go up to 5.17v, input/output filtering, input protection (ntc+fuse), it can do 6A easily with no voltage dropping, the only issue it's that may not have output protection... I tested up to 9.5A and the PS keeps working (without any voltage drop!). This may be a huge issue, so the PS can work until its own destruction. Based on the L2263 IC.
There were dents here and there, I couldn't even plug in the cable without removing the seal and fixing the frame. Should be wrapped in bubble wrap.
