  • Works great as described, so happy I found this!
Our Google Nest thermostat kept losing power and after purchasing this power adapter I successfully installed it and now my thermostat has consistent power at a great value. Thank you

  • Purchased for my Nest thermostat.
So, my nest thermostat did well for about a year and ended up not holding a charge, in the winter time of all months. Also, wasn’t letting me adjust the temperature whenever I was away because the battery was too low. I did some research online and found out that this is something that happens to a lot of users if they don’t have a common wire. Since the common wire is what charges the Nest. (I literally have no idea about HVAC systems) I purchased this, and took some trial and error in getting it to work. But I have to say, since I got it finally wired up properly I’ve had no issues with my thermostat. ... show more

  • Works great for a Honeywell thermostat
Only had a 2 wire for my thermostat. Added the Hottop 24v for my new Honeywell, It's been over a month with no problems. Eazy connection. Wire Attachment line nails should be a little longer.

  • Easy to install, but cord length is a bit ridiculous
I have a Nest in a system with a common wire. It works 90% of the time, but when it gets too cold I need to pull the Y (cooling wire) because without the power from that line, the furnace will short cycle. I didn't want to run a new thermostat wire and the add-a-wire kits haven't worked in my setup. This kit does work. It installs easy- for me, all I really needed was to run the wire and plug in it to the C terminal. Fishing it through the wall wasn't an option, so I just ran it behind the base plate. If you try to do it right under the Nest itself, the Nest won't seat properly. I hooked up one wire to the C terminal and the other to Rc and that was that. I'm not sure hooking up Rc is strictly necessary in my setup, but it saves having to trim and cap the wire (which you would have to do since it is hot). One other huge plus is the UL certification. Looking for this kind of thing, you'll find a bunch of other products that are available that are not UL or ETL certified. These certifications are a hugely important thing to look for. These certifications ensure that the product was safety tested and for anything drawing power, you really want to have those certifications. You can also look for CSA (Canada) and CE (EU) certifications, but those are obviously tested to Canadian and EU standards. Still, any kind of certification is better than nothing. Only real negative for me are the cord length. 23' long cord is overkill, but since you can trim it, it's largely just a nuisance. I guess it could be good if you wanted to fish it through the wall, but if you're doing that, you might as well just run a new thermostat wire. ... show more

  • Worked like a charm
Unscrew the screws on the back of your ring and wrap the wire around the screw. Worked like a charm.

  • Does not work with SimpliSafe doorbell
I bought this adapter for my SimpliSafe door bell, couple of months ago, and i didn’t start installing until now. Before I actually install the doorbell I tried it first to make sure that it works. Well, it does not work, it’s not powering up the doorbell. I tried different ways and made sure that wires have a good connection with the unit. Since i bought it couple months ago , I’m out luck because I can’t return it. Just FYI everyone! ... show more
