CCC certified solar power bank 20000mAh digital display with wireless charging flashlight
-Principle of solar charging: Based on the photovoltaic effect, when sunlight shines on semiconductor materials such as silicon on a solar panel, photons excite electrons, producing electron hole pairs. The electric field causes electrons and holes to move in the opposite direction to form an electric current, which is then collected into a battery through metal wires to complete energy storage.
Large capacity solar power bank: With a battery capacity around 20000mAh, it is suitable for long-distance travel or charging multiple devices,
Multi functional solar power bank: equipped with various functions such as LED lighting, wireless charging, multiple USB output interfaces, etc., it can provide additional convenience in outdoor activities such as camping.
Using solar energy as a clean energy source for charging, reducing dependence on traditional power sources, and in line with the concept of sustainable development; Charging can be done anytime and anywhere during outdoor activities without the need to find a power outlet; Long term use can save electricity costs, especially in areas with high electricity prices.
