Never Miss a Visitor Again with Our Battery-Free Wireless Doorbell!

Say goodbye to the hassle of dead batteries and complicated wiring. Our innovative wireless doorbell uses kinetic energy—a simple press of the button generates its own power to send a signal. With two plug-in receivers included, you can place one upstairs and one downstairs, ensuring you hear the door from anywhere in your home or office.

Key Features:

• 🔋 Kinetic Self-Powered Technology: The transmitter requires no batteries ever. It converts the energy from your press into a wireless signal. Eco-friendly and maintenance-free.
• 🏡 Dual Receivers for Full Coverage: Includes two indoor receivers. Simply plug them into any AC 100-240V socket. Perfect for multi-level homes, large apartments, or offices to ensure the chime is always within earshot.
• 🔧 Effortless Installation in Minutes: Choose your preferred method. Mount the transmitter instantly with double-sided tape, or use the screws for a more permanent fixture.
• 🎶 Customizable Alerts: Choose from 38 unique ringtones and 4 adjustable volume levels, including a silent mode with a flashing light indicator—perfect for when the baby is sleeping or for quiet environments.
• 💧 IP44 Waterproof & Durable: Designed to withstand the elements. The transmitter is rainproof and sun-proof, making it safe and reliable for outdoor installation.
• 📶 Strong Signal & Long Range: Enjoy a reliable wireless range of up to 150 meters (490 ft) in open areas. The signal easily penetrates 3-4 walls for consistent performance. (Note: For best results, do not install the transmitter on metal or iron doors as they can interfere with the signal.)
