WUYELIN 16.5V Plug-in Doorbell Transformer: Stable Power for Your Smart Home

The WUYELIN 16.5V plug-in doorbell transformer is a compact power hub designed to replace older, underpowered units. With a 16.5V output and 20 VA capacity, it provides steady current to doorbells and security accessories so they respond reliably when you press the doorbell or view a camera feed.

Built for modern households, it accepts standard 120 VAC input at 60 Hz and delivers a safe, stable secondary with an auto-resetting PTC fuse. A bright green LED indicator confirms when power is available, giving you a quick at-a-glance status even from across the room.
