A contractor threw away the power connector for my 7 year old Nest Protect and Google, being the awesome company they are, refused to sell a replacement, told me my only option was to buy a new smoke detector, because my units are more than 1 year old. I guess they don't want to support basic replacement parts on a product that's expected to last 10 years, per the industry standard. Awesome, right?Realizing that's completly unacceptable from a consumer perspective, after spending months trying to source a used replacement, then researching 3D plans for replacement parts from the internet (at least one exists, but you need to add correct connectors into it), I finally broke down and bought this kit because Molex plastic connectors happen to be the correct dimensions to fit, and it came with the necessary ready-to-crimp connectors.Well, I'm here to say, after 3-4 months of use, and proper termination using the correct crimpers on correct-gauge wiring, my NEST PROTECT has been running perfectly. I did need to trim the plastic clip off the side of the translucent plastic, but otherwise it was a perfect fit. Pics attached, or it didn't happen, right?If you're a disenfranchised Google product owner as I am, I can tell you after 3 support calls, they don't care. Buy this kit, and take the power back. Quite literally.

Fixed the issue!

Works for robomow rc308 docking station charge wire.

Needed to redo a broken molex. Was super easy to rewire a new one.It comes in a connected continuous "tray" of connectors. Be careful when snapping of a single connector from the tray. Kinda fragile when its outside the plastic casing.

I used to connect new rechargeable batteries to an old device, fish finder by Humminbird. The previous 8 AA battery pack kept failing – corrosion on contacts. This allowed me to use a 12vdc rechargeable pack.
