Festival/Events Phone Charging
Power That Keeps The Experience Alive.
Every Moment Is Better When Guests Stay Connected.
From festivals and corporate conferences to live shows and trade exhibitions, a dead phone kills the experience before it ends. Joos keeps your audience charged, connected, and fully in the moment.

Attendee satisfaction
Events are built on moments. Low battery takes those moments away.
A dead phone doesn’t just cut connection, it cuts participation. Guests stop recording, stop sharing, stop engaging with the event app, and start focusing on finding power instead of enjoying the experience in front of them.
For event organisers, that means reduced engagement, lower content output, and a less connected audience experience.
- Attendees leave experiences early or move away from key areas just to find charging points
- Fixed charging stations create queues and disrupt natural crowd flow across venues
- Event apps, cashless payments, tickets, and schedules become inaccessible when batteries die
- Battery anxiety reduces social sharing, lowering organic visibility for the event and its sponsors
Joos resolves each of these
Attendees stay free to move, explore, and enjoy the entire event without being tied to charging locations
Portable charging removes congestion and keeps crowd movement natural and uninterrupted
Guests remain connected to tickets, schedules, payments, and event platforms throughout the experience
Fully charged phones increase content creation, engagement, and real-time social sharing

Charging On The Go at The Golden Key: Joos' Offers an Innovative Portable Solution For All
Held on 15th October 2022, The Golden Key was London's first "destination city" event as part of the celebration for King of the Carnival of the City.
