This is a quick and easy way to piggy back and get a hardwired 12v power supply for something in your vehicle. You fuse box is usually easily accessible.

You just remove an existing fuse and put the dual adapter in. Then you replace the fuse you took out and a new fuse to protect whatever you are powering in the double adapter. Crimp the 12v+ cable and add an earth and you are done.

This fusetap comes with a random size fuse

Use for; radar detectors phone/tablet chargers GPS radios additional fans or heaters

This one fits the micro sized fuses. I also have standard and mini fuse taps listed
