12v / Cigarette Lighter Question

Hello,

I have a 2004 Z4 3.0i. I can only seem to find one cigarette lighter (12v) available to me.

Currently, I have it powering my carplay unit. I recently bought a dashcam that is also powered by a 12v lighter. I was looking at buying a splitter, but I'm afraid of the amp draw (since that'll blow the fuse).

I was wondering what else I can do?

Also is the cigarette lighter that I have shown in the image below 15A?

Thanks!
 
I'd give the splitter a go. Neither carplay or a dashcam will draw a lot of amps, like say, a 12v travel kettle would. And if the z4 is anything like my e90 bmw, the 12v socket had a hefty 20A fuse on it.
 
I found an E85/86 fuse diagram I've kept, but only in pdf so I can't post it. :(

But it's Fuse 5 and is 15A so you're OK for up to 180W. If that isn't enough maybe you could fit a higher rated fuse?
 
I think you're looking for this image I found floating around the forums.
Side note, fuse 5 seems to be an always live circuit, I'd suggest finding a switched fuse.
