The mobile phone network has launched a unique innovation which will protect festival-goers from the British rain while boosting phone signal and recharging their device.
The umbrella is powered by a series of super sensitive solar panels, meaning the phone charger is an eco friendly option to recharge your device's battery.
The electrical current generated from the panels also powers a micro antenna, boosting a phone's 3G signal wirelessly.
The multi-purpose gadget, which will be trialled at the Isle of Wight Festival next weekend, also boasts an LED torch for night time navigation and a 'hands free' smart phone cradle.
The Booster Brolly works with a wide range of mobile devices, charging a smartphone battery in under three hours, and the design allows for one handset to charge through a USB port in the brolly handle.
However, any friends making calls from under the canopy could also benefit from the umbrella's signal boosting functionality, as the 3G signal is wireless.
Vodafone's Booster Brolly has been created in collaboration with scientists at University College London.
The Booster Brolly has been created as part of Vodafone's VIP campaign meaning customers can go to some of the biggest festivals in the UK this summer, including the Isle of Wight Festival, Wireless and Reading and Leeds.
