10 Best Doorbell Transformer For Video Doorbell 2025 in the United States

The Newhouse Hardware 3TRAN Tri-Volt transformer is a versatile choice for powering video doorbells like Ring, Ring Pro, and Nest Hello, as well as traditional doorbells. It offers three voltage settings (8VAC/10VA, 16VAC/10VA, and 24VAC/20VA), with the highest setting supporting most video doorbells that require more power. This flexibility means it can replace older, weaker transformers that may cause problems with modern smart doorbells. The transformer is UL certified, which adds a layer of safety and reliability.

Installation is straightforward with its surface-mount design and standard corded electric power source. Its compact size should fit easily into most setups. Users should ensure they select the correct voltage setting for their specific doorbell model to avoid compatibility issues. While the transformer is rated at 3 amps, which is sufficient for single doorbell systems, it might not support multiple devices or very high-power setups.

If you plan to upgrade your doorbell and chimes together, pairing this transformer with Newhouse’s chimes can streamline installation. This transformer serves as a solid, dependable option when you need a straightforward power upgrade for your video or traditional doorbell without complicated installation.

The VIIVRIA AC 24 Volt Transformer is a versatile and highly compatible option for powering various smart devices like Ring doorbells and popular thermostats such as Ecobee and Honeywell. One of its standout features is its long 315-inch cable, which offers flexibility in installation, allowing users to reach outlets that may be further away from their devices. The ease of installation is a major plus, as it eliminates the need for complicated wiring, making it suitable for those who may not be very tech-savvy.

Safety and reliability are also key strengths, as this transformer has received certifications for safe operation, providing peace of mind. Users can benefit from the convenience of a battery backup feature, which solves common issues like low battery alerts without needing to remove the devices for charging.

While the transformer is well-received, some users may find the installation process not as intuitive as advertised, especially if their space or outlet configuration is unconventional. Additionally, being corded limits its portability; it must be used near an electrical outlet. It's important to verify if your specific model is included, as compatibility can vary. VIIVRIA offers a good customer service experience along with a 180-day money-back guarantee, which adds an extra layer of trust for consumers.

Installation is another strong point; the transformer is designed for easy swapping and setup.

In terms of durability and safety, the transformer is built to withstand regular use, and it adheres to safety standards, which is crucial for electrical devices. Additionally, the manufacturers offer customer support and a refund or exchange policy, which adds a layer of reassurance for buyers. Potential users should be aware that the transformer is limited to a specific voltage and VA rating. This means that if you have multiple high-power devices, it might not suffice. Additionally, being a hardwired transformer, it requires some basic wiring knowledge for installation, which may pose a challenge for some individuals. For those needing a solid, reliable doorbell transformer, this model from GIVEUBED strikes a good balance between performance and ease of use, but users with extensive power needs may want to consider larger options.
