C wire adapter 24 Volt Transformer for Ring Doorbell Nest Honeywell Emerson Sensi Smart Wifi Thermostat Ecobee Nest Hello Skybell Thermostat UL Certificated (26ft/8m)

The Nest Doorbell has very precise energy demands, so I took a gamble buying this, but I'm very glad I did! This C wire adapter 24 Volt Transformer is powering it successfully without fail.I've had this powering my Nest Doorbell for several months now, and not one power hiccup has occurred. It was the exact length I needed, so I didn't have to add or remove anything, which was a huge bonus in ease of use. The one recommended by Nest was too short. Even though this cable is longer than what Nest recommends, the voltage drop is small enough that it doesn't interfere with the operation of the Nest doorbell, even at maximum distance. Nice!I definitely recommend this product if the recommended one is too short for your install. It has been solid for me during these last several months.

Purchased this for my nest learning thermostat. I had two wires (red and white) from my oil burner that attaches to a thermostat. As a result you need additional power to charge the nest unit. Black wires plug into c and rc slot. White wire goes into w slot and the red wire stays unplugged. It's pretty easy to wire but getting the wire to the spit may be the only tuff part. This is my second 24v power supply because I shorted the first one. Some folks were saying you can also use a 24v transformer for doorbells at home depot or lowes.

Our home had no previous doorbell so I purchased this transformer to provide power for my new Ring doorbell. The product works as advertised with no issues. It has a very long cord so you don't have to have a plug in right by the door. Connect the two wires to your device, plug in the transformer and done. Very simple.

I used it to power a smart thermostat on a 2 wire system. It was easy to install, and is working fine.

The one I received looked used, looks like someone returned mine, and they resold it as new.The wires were all messed up. It works, no helpful info to guide you inside.But if you order this I guess you should know what you're doing.3stars buy it if you need power/c-wire for your thermostat like Nest. The wire is very long which you can't find else where as far as I know.

I puarchased a Honeywell Smart Thermostat and being in a older home my existing thermostat did not have a C wire to supply power to the new thermostat so I ordered this 24 volt C wire adapter. For the price this item made it easy to have a C wire for power to the new thermostat. It was very easy to fish the wire through the wall so it was not exposed. I would recommend this item to anyone that needs a C wire to power a thermostat.

This installed perfectly and worked well for almost a week. I noticed a humming noise after four or five days, which gradually got worse over the next couple days. It was humming loudly enough to be heard across the house through several closed doors. Apparently the glue holding together the metal plates inside can break apart and the plates resonate on each other. I got a different kind as a replacement and didn't have this issue, so I recommend buying a different one.

That wire could travel from my attic into my basement if I needed it and it packs enough power to support my ecobee thermostat. So if anyone tells you "that won't work" they're just trying to milk you for money. Buy this bad boy attach it to the right connector and plug it in. Done smart thermostat activate. Great product tbh
