Kerui M518 Wireless Doorbell is a self-power generation doorbell. You do not need to buy a battery for it, it can generate power by itself, and that’s why we called it “Self Power Generation”. Even if there is no electricity in the whole world, you still can hear the bell ringing clearly because it will keep ringing for you… Most of our customers are very happy with this product. They feel that the “Self Power Generation” function is really something different compared with other similar products on the market.
