Frequently Asked Questions (FAQ) About Ring Doorbell Power Adapters

Q1: Why should I use a power adapter for my Ring Doorbell?

A1: Using a power adapter provides a constant power supply to your Ring Doorbell, eliminating the need to frequently remove and recharge its battery. This ensures uninterrupted operation, continuous video recording, and consistent alerts, meaning your doorbell is always on and ready to go. It’s a “set it and forget it” solution!

Q2: Is a power adapter compatible with my Ring Video Doorbell 2 and Pro?

A2: Yes, many power adapters, including several listed above, are specifically designed to be compatible with both the Ring Video Doorbell 2 and the Ring Video Doorbell Pro. It’s crucial to check the product’s compatibility list before purchasing to ensure it supports your specific Ring model.

Q3: What voltage and current do Ring Doorbells typically need?

A3: Most Ring Doorbells (including the Battery models and some Pro versions) typically require an 18V to 24V AC/DC power supply with a current rating of 500mA to 800mA. The exact requirements can vary slightly between models, so always refer to your specific doorbell’s manual or the adapter’s compatibility details.

Q4: How easy is it to install a Ring Doorbell power adapter?

A4: Most plug-in power adapters are designed for extremely easy, DIY installation. They usually involve simply plugging the adapter into a standard indoor outlet and then connecting the low-voltage wires to your Ring Doorbell’s terminals. Many come with long cables, allowing flexibility for placement without needing to hire an electrician.

Q5: Will a power adapter actually keep my Ring Doorbell’s battery charged, or just power it?

A5: For battery-powered Ring doorbells, a dedicated power adapter typically keeps the internal rechargeable battery continuously charged. This means the doorbell will draw power directly from the adapter, and the battery acts as a backup in case of a power outage. For Ring Pro models, which are designed for hardwired connections, the adapter provides direct continuous power.

Q6: Can I use these power adapters outdoors?

A6: Most power adapters are designed with indoor-rated plugs. If you need to use the adapter with an outdoor outlet, ensure the outlet itself is weather-rated and covered. The low-voltage wires running to the doorbell are generally safe for outdoor exposure, but the adapter’s main plug unit should be protected from the elements, often by plugging into an indoor outlet.

Q7: What’s the difference between an 18V/500mA and an 18V/800mA adapter?

A7: The “mA” (milliamperes) refers to the current output. An 800mA adapter can supply more current than a 500mA adapter. While a 500mA adapter is sufficient for many Ring doorbells, an 800mA or higher output can provide a more robust and stable power supply, especially for the Ring Doorbell Pro models or if your doorbell experiences heavy usage, potentially reducing the chance of “underpower” issues. Both are generally safe to use as long as the voltage matches.


Choosing the best power adapter for Ring Doorbell 2 and Pro is a smart investment that saves you time and ensures your home security is always active. Consider your specific Ring model, installation needs, cable length requirements, and desired features like safety certifications or extended warranties. With one of these reliable power solutions, you can finally say goodbye to low battery notifications and enjoy truly continuous protection.
