Disadvantages of self-generating doorbell

The price is high, and the power generation is limited due to the weather.

1, the price is higher, and the design and manufacture cost of self-generating doorbell is higher, so the price is generally higher than that of traditional doorbell.

2. Affected by the weather, the self-generating doorbell needs to generate electricity by manual or mechanical vibration, so it may be affected by weather factors, such as the weather is too cold or humid, which may affect its power generation effect.

3. The power generation is limited, and the power generation of self-generated doorbell is usually very small, which means that in the case of frequent use, frequent handshakes or mechanical vibrations may be needed to maintain sufficient power.
