So, you’ve got a Ring Video Doorbell Pro – a fantastic piece of tech for keeping an eye on your home. But if you’re experiencing frustrating “low battery” alerts, inconsistent performance, or even a weird hum, chances are your existing doorbell transformer just isn’t cutting it. The Ring Doorbell Pro is a power-hungry device, and it needs a robust, reliable power source to work its magic. That’s where a high-quality transformer comes in.
Choosing the best transformer for Ring Doorbell Pro can seem tricky with all the voltage and VA ratings flying around. But don’t fret! We’ve scoured the market to bring you a hand-picked selection of top-notch options designed to keep your Ring Pro running smoothly, ensuring you never miss a notification, a visitor, or an important moment. Let’s dive in and find the perfect power upgrade for your smart doorbell.
Why Your Ring Doorbell Pro Needs the Right Transformer
The Ring Video Doorbell Pro requires specific power: typically 16-24V AC with a minimum of 10VA (Volt-Amperes). Many older doorbell systems use lower-powered transformers, which simply can’t provide the consistent energy your Ring Pro needs to operate all its features, like live view, motion detection, and night vision. An underpowered transformer can lead to:
- Frequent “low battery” warnings, even if hardwired.
- Intermittent connectivity or Wi-Fi drops.
- Poor video quality or delayed notifications.
- A humming sound from your chime.
Upgrading to a compatible, higher VA transformer ensures your Ring Pro gets the juice it needs for optimal performance, offering peace of mind and uninterrupted monitoring.

Choosing the Right Transformer for Your Ring Doorbell Pro
When picking the best transformer for Ring Doorbell Pro, consider these factors:
- Hardwired vs. Plug-in:
- Hardwired Transformers: These replace your existing doorbell transformer, usually located in your electrical panel or near your chime. They offer a clean, hidden installation and are ideal if you already have doorbell wiring.
- Plug-in Adapters: These plug into a standard wall outlet and run a cable to your doorbell. They are perfect if you don’t have existing doorbell wiring, want an easier installation, or prefer not to deal with electrical panels.
- Voltage (V) and VA (Volt-Amperes):
- The Ring Doorbell Pro requires 16-24V AC and a minimum of 10VA. For optimal performance, especially with features like night vision, 16V 30VA or 24V 40VA are highly recommended. Higher VA means more power available.
- Compatibility: While our list focuses on Ring Pro, ensure the transformer or adapter is explicitly compatible with your specific Ring model (and any other smart devices you plan to power).
- Installation: Assess your comfort level with electrical work. Hardwired transformers require turning off power and making connections, while plug-in adapters are typically much simpler.
- Cable Length (for Plug-ins): If going the plug-in route, ensure the cable is long enough to reach from your power outlet to your doorbell, with some slack for routing.
Frequently Asked Questions (FAQ)
Q1: Why do I need a new transformer for my Ring Doorbell Pro?
A1: Many existing doorbell transformers are low-powered (e.g., 10VA) and can’t supply the consistent energy your Ring Doorbell Pro needs for optimal performance. This can lead to issues like “low battery” alerts, intermittent connectivity, or a humming chime. Upgrading ensures your Ring Pro gets enough power.
Q2: What are the voltage and VA requirements for the Ring Doorbell Pro?
A2: The Ring Video Doorbell Pro requires a transformer that outputs between 16-24 Volts AC (V AC) and has a minimum of 10 Volt-Amperes (VA). For best performance, especially if you experience issues, a 16V 30VA or 24V 40VA transformer is often recommended.
Q3: Can I use a plug-in adapter instead of a hardwired transformer?
A3: Yes! If you don’t have existing doorbell wiring, or if you prefer a simpler installation, a plug-in adapter is a great alternative. It connects your Ring Doorbell Pro to a standard indoor wall outlet, providing continuous power without the need for electrical wiring modifications.
Q4: How do I know if my current transformer is compatible or powerful enough?
A4: Your current transformer’s voltage and VA rating are usually printed on the unit itself (often located near your chime box or electrical panel). Check these numbers against the Ring Pro’s requirements (16-24V AC, minimum 10VA). If your existing one is lower, an upgrade is likely needed.
Q5: Is it difficult to install a new doorbell transformer?
A5: Installing a hardwired transformer requires basic electrical knowledge, including safely turning off power at your breaker box and making wire connections. If you’re uncomfortable with this, it’s best to consult a qualified electrician. Plug-in adapters, however, are typically very easy to install – just plug them in and connect the wires to your doorbell.
Q6: Will a new transformer stop my chime from buzzing?
A6: Often, yes. A persistent hum or buzz from your existing doorbell chime after installing a Ring Doorbell Pro is a common symptom of an underpowered transformer. Upgrading to a higher VA transformer (like a 16V 30VA or 24V 40VA) typically provides sufficient power to eliminate this issue.
Q7: Can I use one transformer for multiple Ring Doorbells?
A7: While some high-capacity transformers (like 24V 40VA units) can technically power multiple doorbells or chimes, it’s generally not recommended to run multiple Ring doorbells off a single transformer due to their power consumption. Each Ring Doorbell Pro ideally should have its own dedicated power source or a robust transformer specifically designed for such loads. Always check the power requirements of all devices you intend to connect.
Conclusion
Ensuring your Ring Video Doorbell Pro has a stable, sufficient power supply is crucial for its optimal performance and your peace of mind. Whether you opt for a robust hardwired upgrade like the Hardwired Transformer for Ring Wired Video Doorbells or the high-powered Auspow 24V 40VA, or prefer the convenience of a plug-in solution like the official Ring Plug-In Adapter, there’s a perfect match for your home. By investing in the best transformer for Ring Doorbell Pro, you’ll say goodbye to “low battery” alerts and enjoy consistent, reliable security monitoring.
