The output voltage is too high by approximately 10%-15% at the rated input voltage of 120VAC. If your power company boosts its transmission line voltage during the day, the output voltage will be even higher than the 10-15% it already over-generates. I'm guessing this is the result of a lack of manufacturing quality control at the factory in the Far East. Furthermore, one of the output terminal screws was stripped and couldn't be tightened down on the low-voltage wire to the furnace controller. I had to disassemble the output side of the transformer and re-engineer the mechanical arrangement of the screws, replacing them with longer 6-32 machine screws with thumb nuts to attach the wires. With this modification, the transformer is now a mechanical duplicate of the 70-year old transformer it was replacing. Also, the junction box cover plate supplied with the unit was way too flimsy to support the weight of the device. Use a standard junction box cover plate with a center knockout instead. I contacted Honeywell Technical Support and let them know about the over-voltage situation, the stripped screw (as well as my fix), and the flimsy junction box cover plate. ### ⭐⭐⭐⭐⭐ So far so good. Added power to ecobee thermostat. *by J***H on Reviewed in the United States on July 9, 2021* I bought this to power my ecobee smart wifi thermostat. I only had a two wire thermostat, so I initially bought one of those plug-in 24v transformers. That worked, but I didn't like the wire dangling along the wall, and I wouldn't be able to mount the thermostat perfectly flush. So I bought this and mounted it with included screw to a knockout in an adjacent light switch electrical box. I made one more hole in the drywall to fish thermostat wire from new transformer to thermostat, and viola, done! I tested the voltage with a Fluke multi-meter, and like the other reviews state, it does put out 27 volts; however, the ecobee powered right up, calibrated itself and is running now for a few days since install.I actually was concerned about heat output of this transformer, since a different branded 18v transformer that I bought to power a Ring doorbell, got really hot. I touched the transformer after install and powered, and I felt no heat. Now the hard part: Patching up the holes. [sigh] ### ⭐ Should have paid attention to the 1 star reviews *by J***3 on Reviewed in the United States on August 3, 2021* Bought another brand recently that lased 3 days before it died. Should have paid attention to the 1 star reviews on this one as well. What was delivered was not what was advertised. No where did it say that this transformer was a Honyewell product and it was made in China , not the USA as advertised. Could not figure out why my New RING doorbell would not work with this transformer since it was one that came recommended for the doorbell having an Output of: 24 Vac at 40 VA. Finally, an electrician determined that this transformer was putting out 27 volts at the transformer and the doorbell that only requires 24 volts. Disconnected and hopefully when the real Honeywell transformer arrives, I will find out if my new doorbell has been fried or not. Learn from my mistakes, do not buy. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/82504773-transformer](https://www.desertcart.com.sa/products/82504773-transformer) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-06-02*
