USB Wireless Doorbell – 150m Range & 38 Melodies

Use a USB power source for your indoor visitor chime with this wireless doorbell. The compact receiver has a rear USB-A plug that connects to a suitable 5 V source, while the separate battery-powered button sends the alert wirelessly. This gives you an alternative to a chime with fixed mains prongs and can make receiver placement more flexible where USB power is available.

The receiver offers 38 melodies and three volume levels. Separate side buttons handle pairing, volume and music selection, putting the everyday settings on the chime itself. Choose a sound you recognise easily and adjust the volume for where the receiver will be used. The transmitter has a bell-marked push area and a blue indicator strip in a white rectangular body.

Wireless communication operates at 433.92 MHz, with a rated range of up to 150 m in unobstructed open space. Indoor reception depends on the building layout, walls, floors and other obstacles. This is a connection between the button and receiver, so there is no signal wire to route between them. Position the receiver where the sound is useful and the transmitter’s signal can reach it.

The transmitter uses a CR2032 battery type and measures approximately 77 × 45 mm at the front. Its battery supply allows it to be positioned separately from the USB-powered chime. The receiver can also operate from a compatible power bank, which is useful when you want the alert near a temporary seating or work area while remaining within wireless range.

Besides visitor notification, the push button can provide a simple everyday household call signal. Someone in another area can press it to sound the chime where the receiver is placed. The direct pairing and sound controls, USB power connection and selectable melodies make the system practical for that agreed notification routine.
