Detailed ways

The technical solutions of the present utility model will be described in more detail below in conjunction with the accompanying drawings and embodiments. the

In order to achieve the above purpose, as shown in Figure 1a and Figure 1b, the solar charger described in the utility model includes a charger housing 1 that can cooperate with the portable device body, a solar battery panel 2, a solar charging control circuit 3 and an output interface 5 . the

The solar battery panel 2 is located on the surface of the charger housing 1 and can be packaged with a transparent material to protect the solar battery panel 2 . The solar charging control circuit 3 is connected to the solar battery panel 2 through a wire 4 or any other current conducting element, and an output interface 5 is provided on it. When the solar charger is matched with a portable device, the output interface 5 should be compatible with the portable device. The power input connector on the device or the electrodes on the exposed surface of the rechargeable battery are in contact. In addition, the output interface can be made of elastic material to ensure good contact performance. the

After the solar panel 2 converts the received solar energy into electrical energy, it sends it to the solar charging control circuit 3, and the solar charging control circuit 3 converts the electrical energy into electrical energy suitable for use by portable devices and then transmits it through the output interface 5 on it Into the power input interface on the portable device or the electrode on the exposed surface of the rechargeable battery that is in contact with the interface. the
