Do you hate it when your phone runs out of battery at a festival and you can't ring your mates, Facebook stalk that person you met at the front of the Slayer set, take that essential selfie to post on Instagram or just play Candy Crush Saga in-between bands? Yep? Us too.

Fortunately, we've invited Volt along who provide a handy portable charger you can rent for the weekend. It's small enough to fit in your pocket, meaning you can keep your phone powered while you enjoy the festival you've come to experience in the first place.

You can rent a Volt charger when you get to the festival, but to guarantee you've got power the whole weekend, you can book in advance online at a reduced price.
