But guess what!? This cord works! And now I can sit here and write this review cause I can see the screen is on and I mounted it back up on my wall.

Plugged into an outlet surge suppressor, it worked perfectly for eight months, powering a small dehumidifier. Then it DIED. I am SO sick of faulty electronics.
