There is an error in the Amazon website. The Transformer output is of 18V AC and not of 16 VAC as mentioned in the website. The technical description says "Doorbell Transformer, 16V / 800mA Power Adapter" The adapter itself clearly and correctly says 18 VAC. Anyhow I tested the output and the multimeter gave me 18 VAC and quite stable. The description should be corrected, I reported it but they have not done the correction. **Q: Is there a way to secure or lock the adapter to the outlet ? I want to use this for my rental TH and don't want guest to unplug it.** A: I just put a lock box over the outlets. The only way a person could unplug it would be to literally cut the cable that goes in and outside of the box. They sell the boxes on Amazon (very cheap) and you can even get metal ones if desired and most are weatherproof if needed. Not sure if this helps, but again, the boxes come with a corner 'hole' that is specifically for a lock. Again, hope this helps you! I'm just a customer too... **Q: Will this charge a ring doorbell 2** A: Yes, so long as the distance isn’t too far (you can calculate the voltage drop if needed). I use this transformer on a Ring Doorbell 2, and I’d estimate the distance between my transformer and doorbell is about 75’. ## Frequently Bought Together - Doorbell Transformer, 18V / 800mA Power Adapter for Ring Video Doorbell, Ring Video Doorbell Pro and Ring Video Doorbell 2, Transformer Compatible with Nest Hello Doorbell and Zmodo Smart Doorbell - 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/141182790-doorbell-transformer-18v-800ma-power-adapter-for-ring-video-doorbell](https://www.desertcart.hr/products/141182790-doorbell-transformer-18v-800ma-power-adapter-for-ring-video-doorbell) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-22*
