Great little invention, works great! But note: On my new 2019 Subaru Outback ( not sure how many brands??) the mini fuse technology has changed and been re-designed. When I pulled the mini fuse out of the fuse block, it has changed and is a new design. The adaptor works great and saves from having to cut and tap into the cars wire harness! “The surprise” was the mini-fuse has changed. There is now a solid molding between the tabs and the fuse link is now between the tabs. Looks like the goal was to “shrink” the molding to make the fuse even smaller. THERE IS A NEW CLASS of fuses coming your way ( Mini fuse 2 or whatever??). I did not want to use the 15 amp Blue fuse that comes with the adaptor so went to the auto store to get a 5 amp fuse. The 7.5 amp fuse I pulled would not fit into the adaptor. The adaptor slots work great and plugs directly into the car fuse block. I hard wired my radar detector and Garmin GPS (did not want to use the cigarette lighter socket).. Again, this is a great and easy way to get power off your MINI FUSE BLOCK without damaging any of the car wiring. Assume on pre-2019 cars the mini fuse blocks have not changed over to the new fuses?
