There are many choices when powering a wired Ring Video Doorbell.  Most people just reuse their existing doorbell power, but I wanted to see if I could improve that situation. When I first hooked up my Ring Wired Doorbell , I used an existing Honeywell Plug-in AC Transformer .  These AC transformers are very popular for both video doorbells, traditional doorbells, and security systems.  They reduce standard home voltages (120VAC in North America) to 16.5 VAC. In contrast, modern DC power adapters for home electronics are efficient. There are global efficiency standards on modern adapters , and in the USA the current efficiency standard is called "Level VI".  These efficiency standards help ensure that idle equipment has near-zero power draw, and that active equipment isn't wildly inefficient. The thing is, the standards are for modern single-voltage DC power adapters, but given that my Ring Wired Doorbell was hooked up to my home's 1990's vintage AC doorbell ...
