18V 50VA Alarm Systems Security Gate and Doorbell Transformer,Plug in Transformer Compatible with All Versions of Doorbell ，Gate Opener Replacement Transformer for Automatic gate openers FM500 FM502

So most doorbell systems are 16v or 24v as far as I can research so most AC/AC doorbell transformers are made to those 2 voltage specifications. Unfortunately neither of those options work out in my situation.I decided to get a nice new Ubiquiti Unifi G4 Doorbell Pro which is fancy but fancy also means power hungry. When powering this doorbell with a normal 16v 30va transformer, my camera would sometimes report power dips into 12v. Yikes.. that's some huge voltage drop especially through my houses old doorbell wiring.My readily available option was to get a 24v transformer at my local hardware store but those are not really safe on my 16v mechanical chime. Rewiring with thicker gauge wire was also not an option unfortunately.Here comes this particular transformer after hours of researching what might be best. It has just enough of a voltage bump to overcome my old doorbell wiring but not enough, really, to harm my mechanical chime. My voltages have stabilized and my doorbell isn't warning me about underpowering it now. I'm assuming this would be a great option for anyone else looking to power a powerful doorbell camera like a Ring Pro or Nest while keeping a 16v mechanical chime.Time will tell how long this will last but my setup has been happy for a week so far. Here's to hoping for a long life

I have a very long loop of wire from my front door doorbell to the attic where the transformer is located and then to the chime unit. Using a 16VAC transformer would sometimes cause my doorbell camera to reboot as I think the voltage drop on the loop was just a bit too high. Using this 18VAC transformer the issue is gone. The camera hasn't rebooted in over a month of use.

Ordered twice. First one had a cracked case because of poor packaging. The second one also had a cracked case as well but I needed the transformer so I plastic welded the case myself to repair it. How does Amazon reimburse me for that or give me a discount?

Stopped working after a few minutes of use. No clue why but no power.

very good product

Long delivery time and arrived damaged. Wish I could get it exchanged but in a hurry
