This umbrella, developed by Vodafone in partnership with Kenneth Tong University College London, is made from a carbon fiber structure and is designed to be a mobile charger environmentally friendly, since it has several panels flexible solar.
The energy collected is processed and stored in a small battery installed in the support cable to the cap through a USB connection, the battery enables charging of a mobile phone in less than three hours.
The energy generated by the panels also feeds a antenna that increases 3G signal. The antenna is installed on top of the hat and increases the signal strength for any mobile phone that is less than a meter away.
