LIANSUM 24V Transformer C Wire Adapter for Thermostat and All Versions of Ring Doorbell, Compatible with Nest 1st/2nd, Ecobee, Honeywell,Sensi, Sensi Smart WiFi Thermostat,Nest Hello Doorbell Supply

Works very well , lots of YouTube videos on where and how to install it.

Basic instructions were included. Very long cord was nice to have. Worked out well.

AMAZON, this is why you get all of my MONIES. I FINALLY found the correct item to keep my Ring Doorbells charged without baboon to take them down every month to charge. I've bought solar panel after panel just to return them and I was at my wits end then I came across these. They work perfectly. Easy to install, just plug in any regular wall socket. No mos power supply. Durable, I got the 26in so more then enough wire length to run from Ring to plug.

The adapter works as advertised.

Allowed me to install my Honeywell Smart Wi-Fi T-stat with my non-standard home HVAC system

Does not function as a proper C-wire replacement. Thermostat drops connection.

The item was as advertised and works. 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.

Great transformer. Comes with a really long cord.

Muy funcional, es tal cual como se muestra en las imágenes.

Funciona perfectamente

Funciona bien con el Ring y llego muy rápido y todo muy bien

Ya no pude regresarlo, no lo pude instalar dentro del tiempo para devolución y cuando lo hice el transformador no servía
