I was recently sent a Wireless Doorbell from Koopower (Amazon link) to review.
Like with most wireless doorbells, this Koopower kit has a transmitter bell to attach by your door, and a plug-in receiver that plays the chime. What sets the Koopower kit apart is that the transmitter doesn’t require any batteries.
The energy required to transmit the signal is generated by the action of pushing the button. This gets around one of the major problems with traditional wireless doorbells – knowing when the batteries are flat. Short of testing your own doorbell regularly, you run the risk of someone pressing the button and there being no chime, even when you’re in.
The Koopower kit I received contained two receivers, which is useful; I have one downstairs and one upstairs. Our house is quite long with thick walls and in the past I’ve struggled to hear our previous doorbell.
Pairing them with the transmitter was straightforward, and the transmitter includes a double-sided sticky patch for attaching to your wall/door. Compared to my previous wireless doorbell, installation was really easy.
Once installed, a couple of buttons on the receivers let you control the volume, and choose one of 25 polyphonic ringtones to play. I stuck with a simple ‘ding dong’ sound, which is the default. The receivers also flash an LED when they ring.
Whilst more expensive than other wireless doorbell kits, the Koopower system gains points for its incredibly simple installation and offering two receivers. It’s not a smart doorbell system like Ring (Amazon Link), so it won’t link to your phone. But it does well for a basic doorbell system that requires minimal maintenance.
