Used this for my ecobee and it worked perfectly. Didn’t have access to the rooftop HVAC so had to find an alternative.

Great product, basically plug and play, purchased this product for my Ring battery Doorbell, the battery has to be charged almost every month in the cold season, decided to try products and was quite happy that I did, two days after installing the product the battery went from 71% to 89%, tells me that it’s definitely working, highly recommended.

I bought this to go with my Nest Doorbell, since the battery powered one would be useless in the middle of winter in Quebec.Since my house has no transformer for a doorbell or existing wiring, I bought this adapter, drilled a hole through the doorframe to where the bell was going, hooked up the adapter to the doorbell, placed it, and plugged it in. Doorbell powered up no problem and has been operating non-stop for over a year now.This power brick has a massive cable, you're probably not going to need all of it, but it's great to have more than less if your plug is further away from the door.This is a great option if you don't want to drop money on wiring up a doorbell, and can deal with a slight bit of cable mess for your smart doorbell.

Didn't want my aunt to have to keep swapping out batteries all the time. This worked great to keep her doorbell fully charged.

I bought this transformer cable specifically to power my Ring doorbell, and it’s been nothing but a headache. Right out of the box, it felt cheap and flimsy, but I figured I’d give it a try. Big mistake. The doorbell kept showing a ‘low voltage’ error, and after troubleshooting, I realized it was the cable’s fault. Completely useless for its intended purpose! Don’t waste your money on this junk. Wouldn’t recommend it to anyone.

Appears to be of very good quality, and an extremely long cord is very helpful.

I have three Ring video doorbells and the power adapters power them perfectly.I would have liked it better, if the instructions wad clearer about the fact, that there is no polarity to be concerned with.Also, it would have been nice if the instructions explained that the light up ring around the doorbell button will now turn on and stay lit...forever.Most doorbells these days have a little light source inside the button to do the same thing. But without anything being said about that in the instructions, My first thought was that unit was damaged somehow.Luckily, it turned out to be totally normal.
