Having a smart video doorbell like the Nest Hello is fantastic – it keeps you connected to your front door no matter where you are. But to ensure it runs smoothly, without annoying “low battery” warnings or connection drops, you need the right power source. That’s where a reliable doorbell transformer comes in. An underpowered transformer can lead to all sorts of headaches, from inconsistent performance to a constant buzzing sound from your chime.
Choosing the best doorbell transformer for Nest Hello isn’t just about grabbing the first one you see. It’s about matching the right voltage and VA (Volt-Ampere) rating to your specific doorbell’s needs, ensuring consistent power delivery for optimal performance. Many smart doorbells, including the Nest Hello, often require more juice than older, traditional doorbell systems.
We’ve done the legwork to help you find the perfect power partner for your smart home security. Here are our top picks for the best doorbell transformer for Nest Hello, designed to keep your doorbell running like a charm.
Why a Good Doorbell Transformer Matters for Your Nest Hello
Your Nest Hello needs consistent power to function correctly. Without it, you might experience:
- Frequent “Low Battery” Notifications: Even if hardwired, if the transformer isn’t providing enough power, the internal battery might drain.
- Intermittent Operation: Your doorbell might go offline randomly or struggle with features like live view or motion detection.
- Chime Issues: A weak transformer can cause your indoor chime to buzz, hum, or not ring at all.
- Shortened Lifespan: Inconsistent power can put undue stress on your smart doorbell’s components.
Upgrading to the correct doorbell transformer ensures your Nest Hello has the stable power it needs for reliable operation, giving you peace of mind.
Key Factors to Consider When Choosing a Transformer
Before diving into the reviews, let’s quickly touch on what makes a good doorbell transformer:
- Voltage (V): Nest Hello typically requires between 16V and 24V AC. Always check your doorbell’s specific requirements.
- VA (Volt-Ampere) Rating: This indicates the total power output. For Nest Hello and similar smart doorbells, a 20VA or higher is generally recommended, with 30VA or 40VA being ideal for robust performance and to handle internal battery charging.
- Compatibility: Ensure the transformer explicitly states compatibility with Nest Hello or other smart doorbells.
- Safety Certifications: Look for UL certification, which guarantees the product meets certain safety standards.
- Installation: Consider whether you prefer a hardwired transformer (replaces your existing one in the electrical box) or a plug-in adapter.

FAQ Section
Q1: What voltage does my Nest Hello doorbell need?
A1: The Nest Hello video doorbell typically requires 16V to 24V AC power. It’s always best to check your specific Nest Hello model’s documentation for the precise voltage requirements to ensure optimal performance.
Q2: What VA rating is best for Nest Hello?
A2: For the Nest Hello and other smart video doorbells, a transformer with at least 20VA (Volt-Ampere) is recommended. However, for more consistent power delivery, especially to charge the internal battery and avoid “low battery” warnings, a 30VA or even 40VA transformer is often considered ideal.
Q3: Can I use my old doorbell transformer with Nest Hello?
A3: You might be able to, but it depends on the old transformer’s specifications. Many older doorbell transformers provide only 10V or 16V at 10VA, which is often insufficient for the Nest Hello’s power demands. Using an underpowered transformer can lead to performance issues, so an upgrade is often necessary.
Q4: How do I know if my doorbell transformer is underpowered?
A4: Common signs of an underpowered transformer for your Nest Hello include: frequent “low battery” notifications despite being hardwired, intermittent Wi-Fi connectivity, a buzzing or humming sound from your indoor chime, or the doorbell occasionally going offline.
Q5: Is it hard to install a new doorbell transformer?
A5: Installing a hardwired doorbell transformer typically involves working with your home’s electrical wiring, usually in a junction box. While it’s generally a straightforward DIY task for those comfortable with basic electrical work, always remember to turn off the power at the breaker first. If you’re not comfortable, it’s best to consult a qualified electrician. Plug-in adapters are much simpler, as they just plug into an outlet.
Q6: What is UL certification and why is it important for doorbell transformers?
A6: UL (Underwriters Laboratories) certification means a product has been tested by an independent safety science company and meets specific safety standards. For doorbell transformers, UL certification indicates that the product has been evaluated for electrical safety and reduces the risk of hazards like overheating or electrical fires, greatly improving safety and longevity.
Q7: Will a new transformer stop the buzzing sound from my chime?
A7: Yes, often a buzzing or humming sound from your indoor chime is a sign that your doorbell transformer isn’t providing enough consistent power to the smart doorbell. Upgrading to a higher voltage and VA transformer, like a 24V 40VA unit, can often resolve this issue by providing the stable power your Nest Hello needs.
Q8: Can I use a transformer for multiple doorbells or thermostats?
A8: Many modern doorbell transformers, particularly those with higher VA ratings (like 30VA or 40VA), are designed to power multiple devices simultaneously. Check the product specifications for “Power Multiple Thermostats/Doorbells” or similar wording to confirm this capability.
