16 Pack 4 Types Fuse Tap, Upgraded 12V Car Add a Circuit Fuse Tap Kit - Standard Mini Micro2 and Low Profile Mini Fuses Taps, ATO ATC ATM APM Fuses Adapter Jumper for Cars Trucks Boats

So far so good. Just installed in an older Jeep fuse panel to power a dual ACC adapter (USB plug & camera plug) and it works. I don't know how to install it to be on all the time so just followed what others have done by attaching red fuse wire & plugging in the positive end to the fuse panel and the negative end to a metal screw to ground (red and black wires from dual ACC adapter). Thank you to others that indicated how to do this and importance of putting your existing fuse in the slot of this fuse adapter closest to the tongs and the additional backup fuse in slot behind your fuse. Would have been nice to have these simple wiring instructions included in the fuse adapter box as a chart to follow.

These are great! If you wanna safely add a device to you're fusebox power these are perfect! They also come with fuses. These enabled me to add a Niilight 3 rocker switch to my van that only gets power when i start my Van. Just make sure you hook into fuses that can handle the power draw of the item you need to power. I would definitely buy.these again.

Very nice quality and easy to use. Worth keeping a few around!

Good fuse extender

Did the job. The provided fuses don’t go all the way down in the tap connector but the original ones did. Hence one less star short of five. I am gonna have to get some other lesser amperage fuses anyway and make a swap. Overall satisfied. I can recommend this item.

These are great! You absolutely can not beat the price either

These taps are a dream to use. They piggyback off an existing electrical circuit and let you install a second device that will also be protected via fuse. The old days of chopping up wires from under the dashboard is over. You simply access the fuse box, choose an appropriate circuit to tap into and plug this in. I installed a multi cam rear view mirror and a separate dash cam in half the time,thanks to these simple adapters.

The low profile mini’s didn’t work. They powered the original circuit, but not the added one. It’s weird because some of the other sizes worked fine, which is why I’m not trashing them with a 1 star review. The provided fuses are poor quality as well. The intended purpose was for dash cam install.
