The principle of solar backpack:The principle of solar backpack:
The solar panel absorbs solar energy and converts the solar energy into electrical energy, which is stored in the built-in battery, and charges or supplies various mobile phones or electronic products according to different interfaces, and is suitable for emergency use without electricity.
The solar backpack looks like an ordinary backpack in appearance, but the difference is that it has a solar panel in front of it. The solar panel absorbs solar energy and converts the solar energy into electrical charge while storing the absorbed charge in a power box. This power box is hidden inside the backpack and can be directly connected to the charger of the mobile phone, MP3, digital camera for charging.
