My car is about 4 months old and I want to know what you guys think because I have no time to goto the dealer.

One day I wasnt getting power to the adapters so I checked the fuse and yes, it was blown so I changed it with the spare.

I tried it again, I only had my radar detector plugged in, I got power to it, then when i went to plug in my cell charger on the other one, i lost all power again.. Blown fuse? yep again. So i changed it with one of my friends spare fuse and just got power to my radar detector but also had my cell adapter disconnected. I dont get it? So i disconnected my radar and put my cell charger in, I blown another one!.. Could it be something with my cell charger? That doesnt make sense, right? What do you guys think! i dont want to goto the dealership and just have them change a fuse and thats it. Any help will be appreciated.
I have done no mods to the stereo or any electronics. My only mods are intake, grounding, and exhaust

I would try another cell charger. Something might be shorted in the charger. A regular cell charger and radar detector shouldn't pull enough amperage to blow the fuse.
