Every station reports its own status to us in real time, so a jammed slot or an empty cabinet is fixed before your guests notice it.

Point your camera at the code on the cabinet, or tap your card on the screen.

About us

Built in Slovakia, for the places people actually go out

VoltsLine started with a problem every one of us has had: it is half past midnight, the night is still going, and your phone is dead. No photos, no taxi, no way to find the people you came with.

Shared power banks solved that in Madrid, Berlin and Brussels years ago. In Slovakia the service barely exists. We are building the network here — venue by venue, starting with the busiest nightlife and tourist spots in Bratislava.

We run our own hardware and our own software, so a partner venue gets one point of contact, and we can fix a station remotely instead of waiting on a supplier abroad.

For venues

A station costs you nothing and keeps people in the room

We supply the cabinet, the batteries, the installation and the support. You supply a power socket and a bit of floor or bar space.

Guests stay longer

A charged phone means another round, another hour, and photos tagged at your place instead of a dark screen.

You earn on every rental

A fixed share of the revenue from your station, paid monthly, with a dashboard showing exactly what it did.

No more bar-staff chargers

Nobody asks your bartender to babysit a phone behind the bar. Certified batteries, monitored temperature, insured.
