Review: Transformer works with Ring doorbell, original, 2 & pro. - UsThis transformer is fitted with long connecting wires, using with a Ring doorbell 2. It simply plugs into a close, standard, 120 volt electric outlet. Keeps the Ring doorbell 2 battery charged & allows for not needing to recharging the Ring battery. Having continuous power allows additional functions, “live view” & enables longer recording times. Our home is over 53 years since being built. It is already wired for a doorbell. The original doorbell stopped working, so I changed the existing transformer. Unfortunately the doorbell continued to not work. Not sure why the original stopped working but replacing the wiring was more than I was up to. Heck, I spent hours just trying to find the original transformer. After not being able to make a Ring doorbell pro work, I Decided to go with a wireless doorbell & thought why not keep one with a camera. Thus the Ring doorbell 2 was chosen. Found out the ring doorbell pro & the ring doorbell 2 have the same features, but the ring doorbell 2 also has a battery.. hooked up the ring doorbell 2 & it worked fine. Being cautious I thought I should get an extra ring battery. Given that the extra ring battery cost about twice as much as this transformer. Being lazy and frugal I decided to buy this transformer rather than an extra battery that would need to be recharged. Decided to install this transformer so it would be close to the ring doorbell & an electric outlet. Ran the wire along the top of about five feet of baseboard, then along the front door trim until I was about 4 inches from the door trim, on an inside wall, and opposite where both the original and then the ring doorbell was mounted. Drilled a hole through drywall and insulation & used a straightened wire clothes hanger to guide the transformer wire to the outer wall where the Ring doorbell 2 connection sites were & after connecting the wire provided with this transformer to the Ring doorbell It works great. To complete my project I secured e transformer using 5 wire clips, lastly I put a little putty in the hole I had drilled & painted to match the interior drywall. Darn fine job.. By the way this transformer also works with an original Ring doorbell as I gave one to an owner of an original Ring doorbell. Review: This baby really Works ! - Purchased this a year ago and it recently kicked the bucket . I than tried to use reviewers recommended 24volt plug in transformer and ring wirewound resistor which wound up creating an unsafe hot! hot! charging environment for my device and home . I then tried another make 18v plug in transformer which turned out to be a dud . Finally went back to this brand plug in transformer and connected to existing wiring of 25ft with a total wire length of 50 ft and it still works . Brought up charge to 100 % overnight . Hopefully this will last longer than my original one did. Tip : I will be trying this for a while , I will charge to 100 % and than unplug transformer until Ring battery shows need to charge than replug transformer. This will still be much easier than removing ring device to charge battery and will extend transformer life . For extended periods such as vacations just leave plugged in. You can also look at a smart plug for even more convenience. ## Features - Suit For Ring Video Doorbell 2- Compatible with Ring Video Doorbell 2 needs to be paired with an external resistor, Because Ring Video Doorbell 2 requires a resistor instead of a mechanical or electronic doorbell kit, this alternate configuration can run successfully.

The resistor should be included with the Ring Doorbell. **Q: Can I wire this to power my doorbell while leaving the existing wires connected for the chime? Or is that a bad idea?** A: I wouldn't do it. You should have a transformer already wired to the door bell. Use the existing transformer or replace it for a newer and more powerful transformer.

Make sure you DO NOT have this plugged in when making the connection with the butt connectors lol This could burn out the doorbell, the power source, shock you or at least trip the breaker. Camera has been working fine using this for a few weeks now. ## Frequently Bought Together - Doorbell Transformer, 18V Power Adapter for Ring Video Doorbell， Ring Video Doorbell 2,Ring Video Doorbell Pro, Nest Hello and Smart Greet Wi-Fi Video Doorbell,Power Supply - Ring Video Doorbell Wired (newest model), Use Two-Way Talk, advanced motion detection, HD camera and real-time alerts to monitor your front door (wiring required) - Ring Chime --- ## 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.hr/products/97659127-doorbell-transformer-18v-power-adapter-for-ring-video-doorbell-ring](https://www.desertcart.hr/products/97659127-doorbell-transformer-18v-power-adapter-for-ring-video-doorbell-ring) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-20*
