Product details
This product does not require plugging in and can charge 5V devices such as mobile phones, portable Bluetooth speakers, tablets, night lights, etc. Even if you are playing outdoors, you don't have to worry about your phone running out of battery;
The product can only be used in sunlight, with a maximum power output around noon sunlight, and there are no white clouds, leaves, windows, anti-theft nets, or other obstructions. Sunlight before 10 o'clock or after 2 o'clock, or weak sunlight, will not achieve maximum output. Buyers should be aware of this!
In a room with lighting, solar panels can hardly measure any value! This is because there is a significant difference in the photon composition between ordinary lights and sunlight! So please test it under bright sunlight!
