How Volt runs lockers and charging at Copenhell, Denmark's biggest metal festival

Copenhell draws around 39,000 festival goers a day to Refshaleøen in Copenhagen for four days in June. It is Denmark's biggest metal festival, and the 2026 edition sold out every ticket category before the gates opened. Volt runs Event Lockers, the Volt Charging Service, and a combined locker plus charging bundle at the event. Here is what that operation looks like, and what it means for other genre music events considering a similar setup.

The festival in numbers

Copenhell launched in 2010 at Refshaleøen, the former shipyard area in Copenhagen harbour. The 2026 edition ran June 24–27 across four stages and featured over 70 Danish and international acts. Every ticket type sold out well in advance, with around 39,000 festival goers expected on site each day, breaking the festival's own attendance record.

The crowd at a metal festival arrives prepared. Four days of outdoor shows means planning phone power for photos, set times, navigation and contactless payments, deciding what to carry through a crowd, and finding somewhere secure to leave a bag when you move to the front. Storage demand at Copenhell is high and predictable year to year.

What Volt runs at Copenhell

Three products cover the operation at Copenhell 2026.

Event Lockers

Personal storage with a code sent to the festival goer by email and SMS just before their slot opens. The lockers sit under cover, measure roughly 30 x 30 x 50 cm, and can be opened and re-locked freely throughout the day with no extra cost per access. Single-day and full-festival booking options are both available. The locker has no power outlet: charging is handled by the separate product below.

Volt Charging Service

The staffed rental product. Festival goers collect a pocket-sized Volt-Charger at a Volt booth on site, pay a refundable deposit, and swap it for a fully charged one once per day at a Volt swapping station. No searching for a free socket, no leaving a phone unattended. The Volt-Charger keeps working in a pocket while the festival goer moves between stages.

Locker plus charging bundle

Both products available as a single booking. At Copenhell 2026 the full-festival bundle was listed at 399 DKK, with a 175 DKK deposit paid at pick-up for the Volt-Charger. For a four-day event the bundle removes the need to book and manage two separate things before arrival, and it locks in the better pre-event price for both.

How the bag rule connects to the Volt operation

Copenhell's official practical information page states that all larger bags must be stored in one of Volt's lockers. That integration between the festival's own entry guidance and the Volt booking flow makes a real difference to uptake. When the organiser's communication points festival goers directly to the service, the friction of discovery disappears before anyone arrives on site. Festival goers who read the practical guide before the event already know where to go; the Volt operation is set up to receive them.

Why the bundle works at a genre event

A metal audience tends to commit. People show up for full days and often the full four-day run. Phones lose charge quickly in that environment: camera use is constant, apps handle payments and schedules, and group messaging runs all day. The locker plus charging bundle addresses the two most common practical problems at this type of event in a single pre-arrival booking.

For an organiser, running both services through one operator means one contract, one service footprint, and a single point of contact for the logistics festival goers ask about most. Volt manages the booking relationship with the festival goer from pre-event purchase to on-site collection. The organiser's own communications point in the same direction, which is what the Copenhell practical information page demonstrates.

What this means for other genre music events

The Copenhell model is a useful reference for any multi-day genre event in Denmark or the wider Nordic market. Three things in particular transfer directly to similar deployments.

First, linking the official practical information page to the Volt booking flow reduces the organiser's support load and shortens the festival goer's search path. Second, a locker plus charging bundle captures bookings that would otherwise split across two separate gate transactions or get skipped entirely. Third, Volt's per-day and full-festival duration options mean the same product range fits a three-day, four-day, or longer format without a separate configuration for each variant.

Volt ran over 120 festivals and events in 2026 across six countries, with more than 40 deployments in Denmark. Organisers at genre music events thinking about a similar setup can reach the Volt team via the for organisers page or at hello@getvolt.dk.
