The solar panel is equipped with a USB interface, compatible with
various 5V charging devices and mobile phones, safe and reliable, and can achieve fast charging.

Intelligent voltage stabilization, constant 5V output,
surface embossing, increasing absorbance by 5%. Using Sumpower battery cells imported
from the United States, the solar conversion rate is as high as 22%.

The first layer of the backpack is honeycomb mesh,
which has good breathability. The second layer is sponge, which has a cushioning effect. The third
layer is foam, which has a pressure reducing and seismic resistance effect.

For various occasions such as outdoor travel,
mountaineering, camping, etc., there is no need to worry about electronic devices running out of power.
A 7W solar panel with a current output of 1A can achieve fast charging.
