I wish it were that simple. It's just a cell-phone charger. Nothing special, just a standard Cellet microusb charger. However, even when I plugged my new Escort Passport 9500ix charger into the cigar outlet, the fuse blew the moment it was plugged in. I went through 3 different 20 amp fuses before I decided to try throwing in the 25 amp fuse. Once I put the 25 in, everything worked fine and stopped snapping fuses.
Interestingly enough, my friend had the same exact issue with his 2012 Volvo S60 and after I did mine, I put a 25 in his as well and his is now working for the first time since he got the car.
I told my dealer about it today and he said he knew nothing about it (of course), but said that he didn't understand why it would snap the fuses instantly either.
I guess it will remain a mystery.
