    Enough power for two Nest doorbells

    Bought to replace an older 18V transformer since I wanted to install two Nest doorbells and didn't have enough power off the older transformer (one doorbell worked, one showed a power low warning) This did the trick and now both have enough power to run.Install was straightforward, just cut power and moved the wires over from the old transformer and mounted it on a punch out in the breaker box.

    Pros
    • Used it to power two door bell buzzzers and a Unifi G4 doorbell camera. All works as you would expect.
    Cons
    • Voltage not what as advertised

    Initial Product received was defective.

    the product did not work at all. ZERO output. I tested the AC at the install location and it had 110 AC. Device produced ZERO out. I retested on my workbench, same result. I requested a REFUND, and instead I received a replacement. I tested the replacement, it does produce 24 VAC on my workbench. I am debating whether to go ahead and use it or request the refund, that I requested in the first place. I am not particularly happy with the results so far.

    Pros
    • No buzzing for unit. Works as it should.
    Cons
    • Good

    Foots the bill on my review.

    Needed a new transformer to be compatible with the RING security doorbell. This is the top one available that I could find after a fairly extensive search. Doing the job well.

    Pros
    • Works great!
    Cons
    • Transformer may not be safe or suitable for use in certain countries or regions

    Revainrating 5 out of 5

    Installed transformer into a surface mounted electrical box.

    I replaced my old 2 wire heat only thermostat and installed a new Honeywell thermostat that required a C wire with 24 volts. I installed the transformer in the furnace room and ran 7 conductor cable to thermostat location for future ac/heat use. The new Honeywell thermostat needed power that the old one did not need. Installation of thermostat and transformer was quick and easy. I ran 2 wires from new transformer using 2 wires from the new 7 wire cable with no issues.

    Pros
    • The transformer worker great with my Ring doorbells.
    Cons
    • Transformer may be too large or bulky for certain applications

    What I needed for 2 Wyze doorbells

    24v seemed to make all the difference for me with my 2 wyze video doorbells lagging/dropping out. made it easy to wire to existing box.

    Pros
    • ‎3.54 x 2.44 x 1.89 inches
    Cons
    • Some users may find the transformer too expensive or unnecessary for their smart home system

    Failed After 4 months

    Installed easily back in early December 2019 on a ring video doorbell circuit. Everything worked perfectly for the first 3 months and then it died. Tested the transformer with a multi-meter and no power output with confirmed power input. I expected it to last many years but since it did not I have to give this a 1 star. Don't waste your time with this transformer, the quality is not there.

    Pros
    • THERMOSTAT TRANSFORMER - A perfect device to operating Honeywell Smart WiFi Thermostat, Sensi Thermostat, Ecobee Thermostat, and Nest Thermostat. Perfect Honeywell 24v transformer
    Cons
    • Transformer may produce a noticeable or distracting electrical smell

    Revainrating 1 out of 5

    Maybe a lemon? for my opinion

    The product seemed durable and of quality but stopped working less than 24 hours after install. The problem is I waited 6 months to install so no return.

    Pros
    • Tools & Home Improvement
    Cons
    • Some users may prefer a more expensive or higher-quality transformer for their smart home system

    Works perfectly with our Nest Hello.

    The item arrived well packaged. There's directions in the box but wiring it up is really straight forward. I bought this to use with our Nest Hello and it works perfectly for that.

    Pros
    • Built with high-quality components, our transformer is designed to last, even under heavy use. You can trust that it will provide reliable power delivery for years to come
    Cons
    • Product may be difficult to return or replace in case of defects or malfunctions

    Works perfectly, comes with knockout connection.

    Really like how this has the connector that goes through the knock out in a wall box. Couldn't see that in the images so it was a nice surprise. Made installation so much easier and now I have a C Wire on my thermostat.

    Pros
    • MORE STABLE CONNECTION - Greater power connection, higher load and longer service life of products. XX type pure copper wire has a small difference in conductivity and more stable current, which is 10% more wire usage than common inverters. Allows more stable charging connection for 2-3 devices at the same time.
    Cons
    • May not be able to withstand heavy usage or constant connectivity without overheating

    Easy to install for Ring doorbell.

    This transformer was easy enough to use and install. I recently purchased this transformer for the addition of a ring doorbell. If needed, I would purchase this again, and definitely recommend.

    Pros
    • Door Chimes & Bells
    Cons
    • Transformer may not be able to provide enough power for high-tech smart home systems or devices

    26.5v on 100' run and fried Ring DB Pro!

    This transformer is way too hot for Ring Doorbell Pro. The output of this transformer at the doorbell was 26.5v and it fried it. I returned the Ring Doorbell Pro to Costco and bought their Doorbell 2 (in warehouse) bc I didn't feel like extending my weekend doorbell replacement project for another week. Before installing new doorbell, I bought a 3 output regular bell transformer from big warehouse hardware store. Used the 16v output and measured 18.5v at the bell. It powered it flawlessly and…

    Pros
    • Easy to install and works great with ring.
    Cons
    • Users may need to purchase longer cables or extension cords to reach the desired location

    Pros
    • Easy to install

    24 Volt 40VA doorbell transformer

    Item was replaced because of failure of previous identical item installed about 3 years ago. Of course it was from China, we don’t get much of a choice anymore.

    Pros
    • Perfect to for ring door bell pro camera. Easy to install and least expensive among options
    Cons
    • Users may experience compatibility issues or glitches when using multiple devices with the transformer

    Working Perfectly good for me

    This upgrade device is working perfectly and solved the issue our Electronic Doorbell was experiencing with insufficient wattage. It was fairly easy to install but the weight of the device in a tight area whilst connecting the electrical wires requires a steady hand and patience.

    Pros
    • ‎Corded Electric
    Cons
    • Transformer may create a tripping hazard when not installed properly or in a safe location

    Easy install more than enough power for my Ring Pro

    Purchased this to use with a Ring Pro. Provides more than enough power and was simple to install. Even the old door bell works now. Also purchased was the Alexa Dot. Got this in case my wife doesn’t hear the bell, She will hear the Alexa announcement &/or see the video on her iPhone; mine too for that matter.

    Pros
    • Performs well with Ring doorbell!
    Cons
    • May not be compatible with certain types of thermostats or HVAC systems

    A+ product and value

    Perfect for the Ring Pro door bell. Installed it in 5 minutes to replace an old bad unit and could not be happier. The extra voltage helps with clarity and night function by making sure ample power stays to the unit with no drop offs.

    Pros
    • Electrical
    Cons
    • Transformer may not be compatible with certain wifi or network routers

    Great with Nest Door Bell

    Now our nest door bell works perfectly. Was very easy to install. The transformer that was installed in the house did not work with our nest. Did a lot of research before we bought this one. Would definitely buy again. Also was a great price.

    Pros
    • Straight forward,easy to install and performs as stated.
    Cons
    • Transformer may be incompatible with certain doorbell models or chimes

    The power rating label is not glued well

    It is ok but the product specification label is not glued well and it separates from the transformer. It obviously has no impact to how product works, but it will be a problem later when someone wants to find out what the rating of transformer is. I could glue it myself, but this tells the product isn't exactly made with quality in mind.

    Pros
    • Transformers
    Cons
    • Transformer may not come with clear or detailed installation instructions
