Solar charging device for mobile phones at city square in Belgrade

Via this posting, I learned that the solar charging device featured in the 3 minute video below was installed late last year in the Obrenovac city square. The structure features 16 ports and can support numerous types of mobile phones, charging them up for free within 10 to 15 minutes. Built-in batteries enable operation at night and during cloudy weather for up to a month without sunshine. An interesting innovation.
