Depending on the combination of chimes and video doorbell hardware you have (or if you want to replace both the front and rear doorbells with video doorbells) you'll likely need a bigger transformer. Doesn't matter if you're installing a Nest doorbell, a Ring doorbell, or even a more DIY-type video doorbell solution like those from Amcrest or similar companies. If you don’t have a doorbell or transformer installed, and you think you’d prefer a battery powered option, you may want to install a Nest Doorbell (battery) instead. Wiring diagrams

If you’re searching for a low-cost but high-quality transformer upgrade, Shenzheny Yelingda’s Door Transformer is the way to go. This 16V 30VA transformer is strong enough to power one or more door chimes in your home. Doorbell transformer output varies by the home's age and where in the world you are, but typically they output anywhere from 8-24V to 10-40VA, with the most common transformer type in the U.S. being 16V 10VA. That means the transformer steps down the AC power of the home's electrical system into a 16-volt AC output with a "power" of 10 volt-amperes. Remember that the calculations were based on current levels determined by a multimeter, so your final numbers may change if your doorbell draws more or less than 0.5 amps. What voltage should a doorbell transformer be? UL has also reviewed and verified the Maxdot chime transformer’s safety, a testament to its better dependability and stability over earlier transformers. Try using the Arlo Secure App to install your Arlo doorbell to see if it works with your doorbell transformer.

In addition to the long run as a tech writer and editor, Jason spent over a decade as a college instructor doing his best to teach a generation of English students that there's more to success than putting your pants on one leg at a time and writing five-paragraph essays. While his days of steering students toward greatness are behind him, his lifelong desire to delight, entertain, and inform lives on in his work at How-To Geek. Here are some common problems that indicate your transformer is underpowered. These examples presume you've tested the wiring with a multimeter and confirmed that there isn't a dead wire or short in the system.

All the best in however you decide to fit, but had to tell my story so you have all the details before making your own choice.In addition to locating your doorbell transformer, go to your chime assembly and look for a label. You will likely need to remove the chime cover to find the model number, wiring diagram, or additional information. What we're looking for is the recommended voltage. I am sorry to hear you had problems with your set up, and I fully endorse your recommendation for safety. One year after installation, my hardware is still going strong with no issues. I fully endorse your recommendation for safety. It's a bit of a simplification, but volt-amperes function in much the same way as watts do in AC nomenclature. If you'd like to dive deep into the differences, you can start by reading up on power factors, but you hardly need an amateur electrical engineering degree to follow along here. To calculate resistance, divide the voltage we need to lower (in this example 8, because 24-16=8) by the current. A multimeter is used to measure current. If, for example, your doorbell system draws 0.5 amps of electricity, the resistance will be 16 Ohms (8V/0.5 amps).
