Are you experiencing issues with your Eufy Video Doorbell, like it constantly disconnecting, not charging, or just acting a bit flaky? Chances are, your existing doorbell transformer might be the culprit. Smart doorbells, especially feature-rich ones like Eufy’s, often need more consistent and robust power than traditional doorbells. Upgrading to a powerful and compatible eufy doorbell transformer can solve these headaches and ensure your smart home security runs smoothly.
It’s a common misconception that all doorbell transformers are created equal. While your Eufy doorbell might initially work with your old setup, an underpowered transformer can lead to instability, poor performance, and even a shorter lifespan for your device. Getting the right power supply is crucial for continuous, reliable operation.
In this guide, we’ve rounded up five excellent transformer options that are well-suited for powering your Eufy (and many other smart) doorbells. We’ll break down what makes each one stand out, their key features, and what users are saying. Let’s dive in!
Why Upgrade Your Doorbell Transformer?
Before we jump into the reviews, let’s quickly chat about why a dedicated, robust transformer is a smart investment for your Eufy doorbell:
- Stable Power: Smart doorbells draw more power, especially when recording, streaming live video, or using night vision. A good transformer provides that consistent juice.
- Prevent Performance Issues: Low power can cause freezing, dropped connections, delayed notifications, or even prevent your doorbell from fully charging its internal battery.
- Eliminate Annoying Buzzing: An underpowered transformer can often lead to an audible hum or buzz from your doorbell chime, which a stronger unit can usually resolve.
- Enhanced Longevity: Providing your doorbell with the correct and stable power it needs helps protect its internal components and prolong its life.
- Compatibility with Wired Chimes: Many smart doorbells need a certain power level to properly trigger your existing mechanical chime.

Frequently Asked Questions (FAQ)
Q1: What voltage does a Eufy doorbell typically need?
A1: Most Eufy wired doorbells, like the Eufy 2K Pro or Eufy Video Doorbell 2C, typically require a power input of 16-24V AC at 30VA (Volt-Amperes) or more. Always check your specific Eufy doorbell model’s requirements in its manual or on Eufy’s official website to ensure you choose the correct eufy doorbell transformer.
Q2: Why do I need to upgrade my doorbell transformer for a smart doorbell?
A2: Smart doorbells draw significantly more power than traditional doorbells, especially for features like video streaming, motion detection, and night vision. An older or underpowered transformer might not supply enough consistent electricity, leading to performance issues, battery drainage, or connectivity problems.
Q3: How do I know if my current doorbell transformer is failing or underpowered?
A3: Common signs include your smart doorbell frequently disconnecting, not charging its internal battery, displaying “low power” warnings in the app, or if your mechanical chime makes a buzzing or humming sound. Sometimes, your doorbell might work intermittently or not at all.
Q4: Is it difficult to install a new doorbell transformer?
A4: For most homeowners comfortable with basic DIY, installing a doorbell transformer is quite straightforward. It typically involves locating your existing transformer (often near your electrical panel, furnace, or chime box), turning off the power at the breaker, disconnecting the old wires, and connecting the new transformer. Always prioritize safety by turning off the power!
Q5: Can I use a 24V transformer if my Eufy doorbell says 16V?
A5: It’s generally not recommended to use a transformer with a significantly higher voltage than what your device specifies, as it could potentially damage the doorbell. However, most smart doorbells have a range (e.g., 16-24V). Always adhere to the manufacturer’s specified voltage range for your specific Eufy doorbell model.
Q6: What’s the difference between Volts (V) and VA (Volt-Amperes)?
A6: Volts (V) represent the electrical potential or “pressure” of the current. VA (Volt-Amperes) is the apparent power, indicating the total power the transformer can supply. A higher VA rating means the transformer can deliver more stable power to multiple or more demanding devices without experiencing a voltage drop. For smart doorbells, a higher VA (like 30VA or 40VA) is often preferred for stability.
Q7: Where is my doorbell transformer usually located?
A7: Doorbell transformers are most commonly found mounted to a junction box near your home’s main electrical panel, furnace, or sometimes directly on the side of your existing doorbell chime unit inside your home. They are usually small, metal boxes with wires connected.
