The real test will be how long it works, but so far so good. I had an older nest thermostat that I wanted to hook up to a Jotul propane stove. The propane stove uses a 2 wire thermostat, so to use the Nest I needed to power it. The power supply was easy to hook up and so far it works fine. ## Frequently Bought Together - 24Volt Transformer C Wire Adapter for Thermostat and All Versions of Ring Doorbell, Compatible with Nest, Ecobee, Honeywell, Sensi, Sensi Smart WiFi Thermostat, Nest Hello Doorbell Supply Cord - Honeywell Home RTH6580WF Wi-Fi 7-Day Programmable Thermostat - Honeywell Home RENEWRTH6580WF 7-Day Wi-Fi Programmable Thermostat (Renewed) --- ## 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.is/products/293842567-24v-transformer-c-wire-adapter-for-all-versions-of-ring](https://www.desertcart.is/products/293842567-24v-transformer-c-wire-adapter-for-all-versions-of-ring) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-08-28*
