It also features an LED torch, a hands-free smart phone cradle and a set of flexible solar panels which - when the weather is nice and bright - can charge your devices too.
The developers claim the Booster Brolly can charge a phone battery in under three hours. The skeleton is made of durable carbon fibre - and it's also windproof.
Dr Kenneth Tong PhD, lecturer in electrical and electronicengineering at UCL said: "The custom canopy has been fitted with 12 lightweight amorphous silicon triple junction solar cells that have the ability to convert light into electricity, through a series of highly sensitive photovoltaic semiconductors.
"The current generated is then transferred, via a voltage regulator, to the handle of the umbrella where it is stored safely in high capacity rechargeable batteries, or used to directly charge a mobile device through a USB port."
Danielle Crook, director of brand marketing at Vodafone, said: "We wanted to create a practical but high tech innovation that could genuinely improve a festivalgoers experience. The concept Booster Brolly does just that by merging cutting edge technology with a trusted and reliable British umbrella."
