Choosing the right power source for your smart home devices can feel like a puzzle, especially when it comes to keeping your Ring Video Doorbell Pro running smoothly. If you’ve ever dealt with “low battery” warnings, chime issues, or flickering video on your Ring Pro, chances are your existing doorbell transformer just isn’t cutting it. It’s time for an upgrade!
The Ring Video Doorbell Pro and Pro 2 are fantastic devices, offering advanced features and crisp video quality, but they thrive on a consistent, robust power supply. That’s where a high-quality doorbell transformer comes in. It’s the unsung hero that converts your home’s standard electricity into the specific low voltage AC power your Ring Pro needs to perform at its peak.
To help you cut through the confusion, we’ve rounded up some of the best doorbell transformer for Ring Pro options available today. Whether you’re looking for a direct hardwired replacement or exploring alternative power solutions, we’ve got you covered.
Why a Good Transformer Matters for Your Ring Pro
Your Ring Video Doorbell Pro isn’t battery-powered; it requires a constant flow of electricity from your home’s doorbell wiring. If your current transformer provides insufficient voltage (V) or volt-amperes (VA), your Ring Pro might:
* Show “low battery” warnings despite being hardwired.
* Experience intermittent disconnections.
* Have issues with night vision or live view.
* Fail to ring your indoor chime reliably.
Upgrading to the correct voltage and VA rating (typically 16-24V AC, 10-40VA for Ring Pro) ensures your device gets the stable power it needs for optimal functionality. Let’s dive into our top picks!

Factors to Consider When Choosing Your Doorbell Transformer
When picking the best doorbell transformer for Ring Pro, keep these points in mind:
- Voltage (V) and VA Rating:
- Ring Video Doorbell Pro/Pro 2 requires 16-24 VAC, 10-40 VA.
- Match or exceed your doorbell’s minimum requirements for optimal performance. Higher VA (e.g., 30VA or 40VA) is generally better for stability.
- Hardwired vs. Plug-in Adapter:
- Hardwired Transformers: These replace your existing doorbell transformer in your electrical box. They are designed for the Ring Pro’s optimal operation, allowing it to ring your existing indoor chime. Products #1, #2, #3, #7, #8, #10 are examples.
- Plug-in Adapters: These plug into a standard wall outlet and run a wire directly to your doorbell. They are great for bypassing existing wiring or continuously charging battery-powered Ring doorbells. While some claim compatibility with Ring Pro, they often bypass your indoor chime. Products #4, #5, #6, #9 are examples. Choose based on whether you want to use your existing chime or prefer a simpler, no-electrical-work installation.
- Compatibility: While most 16-24V AC transformers will work, ensure the specific model lists compatibility with your Ring Video Doorbell Pro (or Pro 2).
- Ease of Installation: Hardwired transformers require a bit of electrical know-how (turning off power, wiring to an electrical box), but many are designed for DIY. Plug-in adapters are typically very easy to install.
- Safety Certifications: Look for UL certification for safety and peace of mind.
- Cable Length (for plug-in adapters): If opting for a plug-in, ensure the cable is long enough to reach your doorbell from an indoor outlet.
Conclusion
Upgrading your doorbell transformer is a simple yet crucial step to ensure your Ring Video Doorbell Pro operates flawlessly. Whether you opt for a robust 24V 40VA hardwired unit or a convenient plug-in adapter, providing stable and sufficient power will eliminate frustrations like “low battery” warnings and connectivity issues.
By carefully considering your Ring Pro’s specific needs and your home’s wiring setup, you can confidently choose the best doorbell transformer for Ring Pro from our top picks and enjoy uninterrupted smart home security.
FAQ Section
Q1: What voltage and VA does a Ring Video Doorbell Pro need?
A1: The Ring Video Doorbell Pro and Pro 2 generally require a power source between 16 and 24 Volts AC (VAC) with a minimum of 10 Volt-Amperes (VA). For optimal performance and to avoid “low power” issues, many users find 16V 30VA or even 24V 40VA transformers to be the most reliable.
Q2: Will a new transformer fix my Ring Pro’s “low battery” warning even if it’s hardwired?
A2: Yes, absolutely! The “low battery” warning on a hardwired Ring Video Doorbell Pro often indicates that your existing transformer isn’t providing enough consistent power (either voltage or VA is too low). Upgrading to a compatible, higher-rated transformer should resolve this issue.
Q3: Can I use a plug-in adapter instead of a hardwired transformer for my Ring Pro?
A3: While some plug-in adapters state compatibility with the Ring Pro, it’s important to understand the difference. The Ring Pro is designed for a hardwired AC power source to ring your existing indoor chime. A plug-in adapter typically bypasses the existing chime wiring and just provides power directly to the doorbell. If using your traditional indoor chime is important to you, a hardwired transformer is the way to go. If you don’t have existing chime wiring or don’t mind relying on Ring app notifications, a plug-in adapter can be a simpler setup for continuous power.
Q4: Is it difficult to install a hardwired doorbell transformer?
A4: Installing a hardwired doorbell transformer involves working with your home’s electrical system, so caution is advised. You’ll need to turn off power at the circuit breaker. However, it’s generally a straightforward DIY task for someone comfortable with basic home electrical work. Many transformers come with clear instructions, and there are plenty of online tutorials available if you need a visual guide. If you’re unsure, it’s always best to consult a qualified electrician.
Q5: What’s the difference between Volts (V) and Volt-Amperes (VA)?
A5: Volts (V) refer to the electrical “pressure” or potential difference. Volt-Amperes (VA) represent the apparent power, which is the product of voltage and current (amps). For doorbell transformers, VA indicates the maximum power the transformer can supply. A higher VA rating means the transformer can provide more current, which is beneficial for power-hungry devices like video doorbells, especially if they have features like night vision or continuous recording.
Q6: My doorbell transformer is located in my electrical panel. Can I still replace it?
A6: Yes, doorbell transformers are commonly found mounted near the main electrical panel, in the attic, basement, or near the chime itself. They can be replaced. Always ensure the power to the circuit is completely off at the breaker before attempting any work. The replacement process is similar regardless of location, involving disconnecting the old unit and wiring the new one.
Q7: Will upgrading my transformer affect my indoor chime?
A7: For hardwired transformers, upgrading to one with sufficient voltage and VA should improve your indoor chime’s performance. If your chime was buzzing or not ringing, a better transformer can provide the stable power it needs. However, if you switch from a hardwired transformer to a plug-in adapter, the plug-in adapter typically bypasses the traditional indoor chime, meaning you’ll only get notifications through the Ring app or a separate Ring Chime.
