Product Details
- 【Safe and Convenient】The doorbell transformer helps you solve the "low battery" problem by directly charging (plug the adapter into a power outlet and power on). The special design and materials ensure the best current output connected to your device. It has a 24V/500mA AC output, so you don't have to worry about your doorbell or thermostat running out of power. Before connecting the adapter to the doorbell, unplug the adapter or turn off the corresponding outlet.
- 【Easy to Install】You only need to connect the two ring copper wire heads from the socket along the wall to the screws on the doorbell bracket, no additional wiring is required to complete it. The installation is very simple and can be completed in a few minutes. The doorbell transformer cable must be secured against walls and corners to prevent wear and tear, which could cause a short circuit on the low-voltage side or leakage on the high-voltage side.
- 【High-quality Materials】The doorbell power supply shell is made of PC fireproof material and British pure copper plug, which can extend the service life of the product. CE certified, good conductivity, stable transmission. Do not bundle the doorbell transformer cable with household power lines (such as air conditioner and refrigerator power cords) or place it near high-temperature appliances such as heaters and stoves to prevent the cable insulation from melting.
- 【Long Cable Design】For your convenience, we customized the doorbell transformer cable to 8 meters, so you can easily plug the doorbell adapter into a power outlet inside the house or outdoors. Do not install the doorbell transformer in humid areas, such as bathrooms or near kitchen sinks. Avoid splashing water or oil onto the adapter. Moisture can cause internal short circuits and leakage.
- 【Wide Application】The doorbell transformer is compatible with most versions of doorbells and is a good helper for your home intelligence. No need to remove the original battery, just connect the doorbell adapter to your video doorbell to charge your device or keep it charged for a long time. The power supply voltage is applicable in Ac8~24v(500mA).

AMFUN Transformers 8m/315inch White (21120.1 cm) Editorial Review
**** The AMFUN 24V 500mA Doorbell Transformer has garnered positive reception from users seeking a dependable power source for their smart doorbells, specifically the Ring and Eufy models. Customers have found the installation process to be straightforward, thanks to the generous 8-meter cable that provides ample length for installation without the need for additional extensions. Many users appreciate the solid Construction of the transformer, noting that it operates without overheating or losing connection after extended use. The primary draw for customers is the elimination of “battery anxiety,” an issue faced by many doorbell users who must frequently recharge their devices. Several reviews highlight how the transformer successfully maintains battery levels, making it a reliable solution for those tired of the hassle of battery replacements. While users are generally satisfied with the functionality of the product, there are a few caveats. One user reported a buzzing sound from the transformer, which could detract from the overall experience, although most reviews did not mention this issue. Additionally, customers noted that those with existing built-in doorbell transformers may not need this device, suggesting that potential buyers check compatibility beforehand. Overall, the AMFUN Doorbell Transformer stands out as an effective and cost-efficient option for ensuring continuous power to smart doorbells while avoiding the inconveniences of battery maintenance. **
