Consistent power adapter

This was my third purchase from Ohmkat, got a 24V Transformer this time. Like before, the item shipped quickly and arrived in good shape. Their products always seem reliable; my Nest Hello Power Supply from last year is still going strong. I keep coming back because their stuff just works and it's easy to deal with them.

Good universal power supply

I bought the Universal Video Doorbell Power Supply last month for my new Ring doorbell. The installation was pretty straightforward, just followed the instructions. It took about 5 days to reach me in Arizona, which was fine. The quality of the adapter felt solid, not flimsy at all. It's been working perfectly since I installed it, no issues with power to the doorbell. I appreciated that it came with all the necessary wire connectors. The short circuit protection feature was a nice peace of mind, too. Overall, it made setting up my doorbell much easier than I expected.

Easy setup, works well

Got the Video Doorbell Power Supply for my new doorbell. It arrived quick and was super easy to set up. Didn't need to call support or anything. It just works as it should.

Hey, thinking about the universal doorbell power supply. Is it really 'universal' or are there some doorbells it just won't work with? Got an August doorbell.

R Rosa 3 months ago

It worked fine for my Nest, and I think it covers most of the big brands like Ring, Nest, August, Skybell. You should be good with an August.

M Mike 3 months ago

My friend has an August doorbell and uses an OhmKat, no problems. It's pretty versatile, designed for most of the popular ones out there.

Does OhmKat ship to Canada? I'm in Toronto and need a power supply for my Nest, but don't want to pay crazy shipping or customs.

R Rachel 3 months ago

I think they do, but you'd probably want to double-check their shipping policy on the site. Customs can be a pain sometimes though.

M Megan Romero 3 months ago

They do ship to Canada. I got my chime from them last month. Shipping wasn't too bad, but yeah, customs is always a wildcard for any cross-border stuff.

Any way to get a discount on my first order? Looking to buy for my new smart home setup.

K Kate 3 months ago

Yeah, sign up for their email newsletter. They usually send a code for your first purchase right after you subscribe.

R Rosa 3 months ago

I got 10% off for signing up for their emails. Worth doing before you order.

Hey, I'm thinking about getting an OhmKat power supply for my Ring doorbell. Are these things actually safe? Don't want to fry my doorbell.

A Andre Kaur 2 months ago

Yeah, totally safe. I've been using one for my Ring Pro for like a year now, no issues at all. It's got built-in protection, so you're good.

A Alex L. 2 months ago

They're designed specifically for smart doorbells like Ring. My buddy used one and it works fine. Don't worry about it.

What's the return policy like if I get one of these and it doesn't work out with my setup? Easy or a hassle?

N Noor P. 2 months ago

It was super easy for me. Had to return a wrong adapter once, just initiated it online and sent it back. No fuss.

M Marcus 2 months ago

I didn't return anything but from what I remember reading, they have a pretty standard return window, like 30 days or something. Should be fine.

Just wondering about the cable length on these power supplies. My outlet is kinda far from the door. How long are they typically?

A Amber Patel 3 months ago

The standard ones are pretty long, like 20 feet usually. They also sell extensions if you need more length though, I saw them on their site.

W Wendy Brooks 3 months ago

Mine was plenty long, I had some extra even. I think it's like 20ft as standard.

Can you stack coupon codes on OhmKat? I have a first-time buyer discount and maybe found another one.

B Ben 3 months ago

Nah, usually only one coupon per order. Most places don't let you stack 'em.

K Kate Hughes 3 months ago

Pretty sure they only let you use one code at checkout. I tried it once with a holiday code and a newsletter one, only one worked.

Does OhmKat have sales around holidays like Black Friday or Cyber Monday? Planning to buy a few things.

N Neil A. 3 months ago

Oh yeah, absolutely. They had some pretty good deals last Black Friday. That's when I grabbed my power supply.

B Ben 3 months ago

Definitely keep an eye out around those times. They usually do promos for the big shopping holidays, saw it during Prime Day too.
