Don't understand what you mean. Using a 13.5v feed instead of 12v is unlikely to damage your box, but you're saying that you plugged something into your box without an ac adapter? If you've connected 240vac mains feed directly into your box you will definitely have fried something, but you would almost certainly have heard / seen / smelt it, so I'm guessing you didn't actually do that!
