  • Great battery adapter
Size: 2 Pack
Being a Milwaukee guy this was a no-brainer, I use this to test 12 volt equipment ,lights, small motors and one of our service trucks use this battery adapter to run all their LED lighting in their tool boxes. with the built-in fuse and switch it makes installation a breeze . we should have purchased these much sooner instead of carrying around 12 volt seal batteries or use a jumper pack. ... show more

  • Great for troubleshooting gear
Size: 2 Pack
Works as expected. Wonderful tool for the bag. This allows me to provide 12 volt power to items when I have little or no options. A great way to prove power for troubleshooting devices. I have powered VHF radios and other electronics without having to care a heavy battery around

  • Works great
Size: 1 Pack
Super cheap, easy slide on design. Great to have the fuse and power switch. I paired mine with a dc-dc stepdown buck converter and alligator clips to be used as a clean dc power supply for bench testing. Just wish it was easier to remove for recharging.

  • Works great and includes extra fuses.
Size: 2 Pack
I'm using these for a new project idea and they filled the need perfectly. Super great value for the money. The connections all fit well and have good construction. This product looks like it will hold up well to rough handling and the battery fits perfectly.

Really useful harness. I use this with a set of alligator clip wires to test car and trailer lights. I really appreciate the built in fuse and switch for doing diagnostic work
