Anyway, I just moved and dug my Ring doorbell out of a box along with this transformer. When I installed it, I included a huge 250 Ohm resister for some reason, got the recommendation online. Regardless, the Ring was not charging, so I tested the voltage from the transformer and got 25 volts consistently, not the 24 volts it claims, and not the 8-24 volts my door bell wanted. Sure, I got an extra volt for free, but I don't know what that will do to electronics without knowing what kind of regulator they are using, if any. So, since it provides more voltage than stated, it might not be approved anymore - I don't know. I bought this in late 2019. **Q: Will this work with the vine 610 thermostat** A: This will work with any thermostat. It simply provides the 24V power needed assuming your tstat wire and doesn’t have the additional wires for 24v power. Most furnaces have the 120/24V transformer, but older homes tstat wire never had enough conductors. Newer homes should. Regardless, yes, this transformer with work. ## Frequently Bought Together - AC 24 Volt Transformer, C Wire Adapter, Compatible with All Versions of Ring Doorbell and Thermostat for Ecobee,Sensi and Honeywell, 315" Long Cable - 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.id/products/69747978-24v-ac-transformer-c-wire-adapter-315-cable-for-ring](https://www.desertcart.id/products/69747978-24v-ac-transformer-c-wire-adapter-315-cable-for-ring) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-09-27*
