Old house modern thermostat
Our house is old enough to not have a C wire for the thermostat. So if we use a modern programmable one it has to be replaced every couple of years when the battery can no longer be recharged. There is a plug just below though, so we bought this to try. Took less then 5 minutes to install and has been working great since.

DId not work as advertised
Although this said it would work for a Nest Camera, we were unable to get this to power the camera at all. We ended up buying a power adapter directly from Google, and it works just fine. This might work for some devices, but it certainly did not work for my Google Nest camera.
Honest Reviews –
Used with Wyze Doorbell v2 (the one that requires you to have an existing doorbell)
First I wanna thank the other reviewer who also bought this for the Wyze Doorbell v2 and left a review stating it works. I never would’ve tried this cuz idk enough about electric stuff to know if my plugs have enough voltage, or if the plug is enough, or good enough for the camera, etc, nor do I have an existing doorbell, so thanks for doing that legwork. I immediately bought this after seeing that review (and the Wyze Doorbell v2 cam as well) and just hooked it up now and it works great! It’s literally as easy as slightly unscrewing the two screws on the back of the camera, make the metal part of the wire touch the screw, the tighten the screw until secure. Then plug other end into outlet. The camera has instructions for this as well, but figured I’d save a future person a few minutes and share 🙂

Quality
2 stars because the product arrived on time and it works. However not sure if it was damaged but something rattles inside as if it’s loose i was afraid it wasn’t going to work but it did!
