Questions about APC C2 power filter
Hi. Sorry if this is in the wrong forum. I bought an APC C2, wall mountable power filter and surge protector for $4 today. I didn't really need it, but I thought it was a great price, and maybe I would sell it. But then I reconsidered that idea, because I read that it has to have the original cord to work properly, and power cord in the picture looks different than the one I have. I also wasn't sure if there was a way I could test the noise filtering. If it's just going to be a surge protector, then maybe I should just return it? I was hoping somebody knows more about this part than me :)
Thanks.
