  • Sufficient wire
Wire is of sufficient length, but I only had to drill through my door frame to the interior of my home and the outlet was right there. It has the polarity (+/-) on the wire it self. Great for video doorbell cameras. But not good for heavy loads since it is a 12v.

  • Nice device
I used it for the Wyze doorbell because I didn’t have an existing wired doorbell. Worked perfectly and the wire nuts were small enough to fit inside the doorbell housing. Finding a place to hide the wire took a lot longer than connection the power supply. Remember, do not plug it in until you have it connected. ... show more

  • Eufy 2K Doorbell
Does the job for a Eufy 2K Doorbell. Haven't had any issues with the battery since. It's nice knowing that I can leave it up all of the time without needing to take it off to charge and leave my porch unmonitored.

  • My Nest Thermostat is happy as am I
Used to power a Nest Thermostat as the boiler system did not have a common C wire. The long cord was a blessing.

  • Works with Amazon Thermostat
I live in a rental and can't run new wiring to get a c-wire, but I still wanted to use my Amazon thermostat, so I bout this. It was easy to hook up with clear directions, and it worked the first time perfectly. I have been using it for a few months now, and I am happy with it.

  • Powers my Doorbell
Perfectly helps to keep my doorbell battery charged. Especially during the winter.

  • Lasted a week.
Had a neighbor install it, not at home to do it. When I got home, wasn’t working, and too late (35 days) to return it. Life…..
