Review: Works great for a Honeywell T9 system - Had to use a cable puller to run it up my wall which was a chore but it all was worth it when I’m able to plug in my Honeywell T9 and get power to run it when my old boiler system didn’t have any C wire. I connected the two ends of this power adapter to RC and C. My boiler heating system connected to W and RH. As soon as I plugged this into the wall it powered right on and worked perfectly. Had to manually add my boiler lines because it’s an older zone valve system but this device worked perfectly.
Review: Produt it works on the Ring camera. - Wonderful product, straight wire, it doesn't matter which side is which, both side does the same thing, easy on installation. The wire is very long. It would have been better if the wire had been 10' shorter. But this transformer keeps the Ring camera charged all the time. Love it. very functional. connectivity is eased.
