Solar Power Keychain

March 20, 2019

There aren’t many standby power sources for mobile devices. This solar keychain power supply is not only compact and portable, but also uses solar energy to continuously reserve power.

Doesn’t it take several hours for such a small solar panel to be fully charged? It can be equipped with additional solar panels to increase the rate of storage. The 500 milliampere battery of this keychain is only enough to charge the iPhone 20%, which is equivalent to the iPhone's power consumption for one hour, but the weak power supply capacity is exactly what the portable power supply has to make. And as long as this keychain power supply is in a light environment, there is no need to worry about its charging problem.

When using a solar panel, it takes about 10 hours to fully charge the compact keychain power supply. When using three solar panels, the charging time can be shortened to 3 hours. If six solar panels are used at the same time, It takes only 1 hour to fully charge. Of course it can also be charged via USB, which takes about 2 hours. The price of this keychain power supply in Germany is now 48 US dollars, and the price of a single solar panel is 9 US dollars. In the coming months, this kind of solar energy keychain power supply is expected to be available in other European countries and is expected to be sold in all countries in a year.
