, the umbrella developed by Dr. Kenneth Tong features 12 hand-stitched silicon solar cells stored in the umbrella's handle that charges the phone's battery. The handle has a USB port that connects and charges the phone. It could take up to three hours to complete the process.

Dr. Tong told TechSpot
"We've put in all of this technology but its not heavy, its not big - and it looks good. In fact, it's a bit of a James Bond umbrella - you can't tell what it does from the outside."
Vodafone says the Booster Brolly will be released to the public at the Isle of Wight Festival on July 22nd.
