So happy with this!

I got the Universal Video Doorbell Power Supply and it's fantastic! Set it up with my Arlo doorbell and it works perfectly. No more battery changes for me! The instructions were super clear, it only took me like 15 minutes. Everything feels really high quality and sturdy. I'm definitely telling all my friends who have smart doorbells about Ohmkat. Will buy from here again!

Solid value for the price

I was looking for a good deal on a Smart Thermostat Power Supply and chose Ohmkat after comparing a few options. I signed up for their newsletter and got a 10% off coupon, which made the price pretty competitive. The product itself feels well-made, and it solved my thermostat wiring issue without any fuss. Shipping took about a week to get to me in Florida, which was okay for free shipping. Overall, I feel like I got good value for my money and the product seems solid so far.

Good Ring power supply

Bought the Ring Doorbell Power Adapter. Installation was easy. It worked as advertised right away. Shipping was fast enough, got it in about 4 days.

Hey, thinking about grabbing one of these power supplies for my Ring doorbell. Are they pretty easy to set up? I'm not super handy but don't want to call an electrician either.

N Neil 4 months ago
Yeah, they're super simple. I put one in for my Nest Hello a few months back. Just follow the instructions, it's basically plug and play.

For sure. I watched a quick YouTube video for mine, took like 10 minutes tops. No special tools or anything. Definitely a DIY job.

What's the deal with their return policy? Like, if I get it and it doesn't quite fit my setup or something, am I stuck with it?

N Nina 4 months ago
Nah, they have a pretty good return window, I think it's 30 days. As long as it's not damaged, you should be fine.

Returns were easy for me last summer. Got the wrong adapter initially, sent it back and they processed the refund quick once they got it. Just make sure to keep the original packaging.
