A 100,000 mAh power bank requires a 10-12W solar panel. The maximum output voltage of the solar panel is 5V, which can be directly charged on the power bank. 5W equals 1000mAh. The charging speed is relatively slow. It should be unplugged when there is no sunlight. There are many thin film solar charging papers on the Internet, generally 10W-12W, which are a combination of power generation chip and inverter. It is very simple and can directly charge mobile phones.
This is indeed the case. Players who have a little knowledge about solar energy will not be scared by Chaoyang solar panels. They will only rationally buy an ordinary brand power bank, but not solar energy. Power bank,
Because the ordinary solar power bank sold in the market has a small solar panel, the capacitycharging ity is too low, especially indoors, its solar function is just a decoration and it is intended to use indoors when charging a solar panel, the charging time should be calculated on a monthly basis to fully charge it.
Solar power bank, except for a small solar circuit board, the power bank output for charging mobile phones, has the same function, several unnecessary solar panels, the price is much more expensive and the capacity is still WRONG.
