We touch various switches, keyboards, and mice every day, but have you ever thought that each touch will generate energy, and you can design many things by collecting these energy. Linbell G4 self generating wireless doorbell came into being. The wireless signal can be transmitted by pressing the doorbell button with fingers, and the doorbell transmitter no longer needs batteries. This time, I was lucky to get a chance to evaluate the machine trial. Let me unveil the new self generating wireless doorbell for you.

Unpacking

The outer package of this product is in the middle distance, and the internal accessories are placed reasonably. The packaging material is renewable paper, which is good both in appearance and feel. The printing design of packaging is simple and generous, with clear data and manufacturer information.

After opening the package, you can see all the accessories, including a host, a transmitter, and a back sticker (3M The double-sided foam adhesive is very easy to use and firmly stuck. The disadvantage is that you can't take it off again if you stick it on.), a manual, and two expansion screws (the manufacturer's design is very sincere, providing users with two installation methods, which can be installed by punching holes or without damage. Have a conscience!).

appearance

The appearance design of the product is mainly white, and the material is pvc plastic. It feels a bit frosty. It feels great, and the G4 self generating wireless doorbell looks more like a doorbell than the round design of G2. It may be that when I was a child, the doorbell at home always had a rectangular shape, so the G4 gives me a very cordial feeling.

As can be seen from the picture, although the transmitter does not use batteries, the host still needs power supply. The G4 host uses 220v AC power supply, which can be said that the entire product does not use batteries, but there is also a problem that the host must be plugged into the socket.

The front design of the host is very simple. The simple logo has two buttons on the front, namely volume adjustment and ring tone switching. The volume can be adjusted in three levels according to different scenes. 25 ringtones can be selected according to your preference. The ringtones are all 8-bit chords, which cannot be said to be beautiful, but they are really enough as ringtones.

Host details: this product doesn't use a three plug socket, so there is no grounding wire. Personally, there should be a grounding wire to ensure safety, because the doorbell host is used all the time. Although it doesn't plug and unplug frequently, adding a grounding wire can better protect the equipment and users.

The speaker is also set on the back of the product, perhaps to ensure the simplicity of the front, but the speaker is designed on the side of the socket. After the power is connected, the speaker faces the wall, and the sound transmission is attenuated. This design should be reconsidered.

The transmitter has a small logo on the front. The overall design and materials are very similar to the host. However, there is a big mechanism in this small transmitter. It can sound without batteries. This is the transmitter. There is no battery equipment inside the transmitter. It uses the kinetic energy generated by pressing, which is converted into instantaneous high-voltage electric energy to drive the wireless switch. It will be explained in detail later.

The key stroke of the transmitter is not very long, which can be seen from the side, about 2cm. The feedback strength of keys is also very good.

On the whole, the appearance of this product is very reasonable, and the overall collocation is also very harmonious. The materials are well made. It can be seen that the overall workmanship of LinkedIn Technology is very good.

user's experience

To install the transmitter, LinkedIn provides two installation methods, and the installation process is also very simple. As long as the back cover of the transmitter is opened, you can install it according to the actual situation in your home. It is recommended to use 3M glue for installation, which can be installed without tools. If expansion screws are used, an electric drill is required, which is time-consuming and laborious.

There is a warm reminder on the back of the gum. The design of Linktop is very humanistic, and important things are marked separately. Understand those of us who don't like to read the manual.

When you press the transmitter, you will receive the sound light integrated prompt from the host. The effect is not so cool, but the prompt effect is good. It's a serious doorbell.

LinkedIn uses 13 parts to assemble its unique micro turbine generator. Each press produces energy. In actual use, the effect is very good, especially the transmission distance is really adverse, which theoretically reaches 30m. In the actual test, three walls can still be used.

advantage:

1. No electricity, environmental protection. The standby power consumption of the host is low.

2. Waterproof when outdoors. (can be pressed in the water)

3. Two installation modes are available

4. The ring tone is large enough and there are many optional tracks

5. Versatile style.

Disadvantages:

1. The button is more laborious than the traditional battery doorbell button.

2. The button pressing sound is louder than the traditional switch bell.
