I have an old power strip which is probably from 2005 or so, and it really has been a great one, but the surge protector went out. It still works and everything, but I'm not sure if it's safe to use. The power light is dim too, but it might suppose to look like that. It's a Belkin F5C595-TEL. Do you think it's safe to use on devices like an iPad, an android phone and so on? Could it short my devices?
