Upgrade your listening pleasure

In order to achieve the next level of music quality with their hi-fi systems, audiophiles often look for a clean, undisturbed grid power. The purity and stability of the grid signal is one of the most critical factors in recognising the excellent quality of one’s audio components.

The grid is influenced by everyday equipment including computers and appliances. Everything is connected to the same dirty grid that is polluted by DC Voltages, high noise levels and various frequencies. All interferences affect audio-quality and even the best power conditioners are not able to completely eliminate the disturbances.

Stromtank has been designed to separate your hifi- system completely from the grid to supply clean, undisturbed power to achieve the next level of music quality with your hifi-system.

Don’t wait until midnight to get the best sound!

The Stromtank is a high-power battery pack with integrated pure-sine wave converter power supply – totally disconnects your audio system from the grid.

The perfect addition for your audio-setup

The next generation Stromtank S2500 Quantum MKII adds upgraded battery management circuitry, latest generation lithium ion batteries, as well as digital distortion suppression technology to all outlets. This new digital distortion suppression technology eliminates digital and backwards interference from other audio components, to provide an even quieter, cleaner background.

With Stromtank S 2500 you can enjoy many hours of listening to music before it connects uninterrupted and automatically with the grid to recharge.

During the recharging process you can listen without any interruption. Even when the Stromtank is connected to the grid, the current pulses are not taken directly from the grid - they are absorbed by the battery. In the AC- connected mode the Stromtank creates a stable AC-supply (amplitude and frequency) and has less interaction between the grid and your audio or video setup.

When the battery state-of-charge reaches a critical minimum, the Stromtank will automatically recharge itself from the mains. Every Stromtank model generates its own AC voltage signal from batteries that are recharged under the control of multiple microprocessors. Once charged, the device is disconnected by an internal power relay. 

With the Stromtank, the quality of premium home theatre equipment is both visually and sonically enhanced.

Handcrafted to the highest standards in Berlin, Germany.
