Volt Charging Service

Refundable deposits
Refundable charger deposit: 150 DKK
Refundable cable deposit: 25 DKK

How deposits work
All deposits are paid at pick-up when collecting your Volt Charger and cable at the festival.
If you already have a Volt Charger from a previous festival or year, you don’t need to pay the charger deposit again.
The same applies to the cable deposit if you bring your own USB-C cable, which we encourage as part of our green initiative.

Refunds
Deposits are refunded to your original payment method within up to 14 bank days after returning your Volt Charger and/or cable at the same festival.

Keep your charger after the festival
No problem — if you choose to keep your Volt Charger, we retain the charger deposit and you keep the device.
Just remember to pick up a free USB-A cable at a Volt swapping station so you can charge it at home.

How long does a Volt Charger last on a full charge?
A fully charged Volt typically lasts for a full day of normal phone use. Battery life depends on your phone model and usage.

How many times can I swap my Volt Charger?
You can swap your charger once per day at a Volt swapping station during the festival.

Can I charge multiple devices at once?
Volt Chargers are designed to charge one device at a time.

Do I need to bring my own cable?
You can rent a USB-C cable on-site with a refundable deposit, but we encourage bringing your own as part of our green initiative to reduce electronic waste.

Can I get a charger for just a single day or a quick top-up?
Yes. If you’re only at the festival for a single day or just need a quick charge, you can buy a Volt SingleBoost on-site.

Volt SingleBoost includes a single charging cycle and follows the same deposit rules for charger and cable. It cannot be pre-booked and is only available at Volt Charging stations during the festival.

What happens if I forget to return my Volt Charger?
If the charger is not returned, the charger deposit is retained and you keep the Volt Charger.

If you choose to keep your Volt Charger, just remember to pick up a free USB-A cable at a Volt swapping station so you can charge it at home.
