Where can I charge my phone at the festival? Anywhere! You can rent a portable battery pack at the ChargerGoGo booths and carry it with you on-the-go. With three built-in cables, you can charge iPhones, Android devices, and more. The charger rental pass is on presale now! The pass allows you to exchange your battery for the entire pass duration as many times as you want, so you will never have to worry about your mobile device running out of battery.
