The perfect addition for your audio-setup…

The Stromtank offers the unique possibility to separate your hifi-system completely from the grid.

The Stromtank is a high-power battery pack with integrated pure-sign wave converter power supply – totally disconnects your audio system from the grid. With the Stromtank you can enjoy up to 8 hours listening to music before it connects uninterrupted and automatically with the grid to recharge. During the recharging process you can listen without any interruptions.

Premium home theatre equipment quality will improve both visually and sonically with the Stromtank.

Boost-function when connected to grid…

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- / video-setup.

The creator of this audio-declaration of independence is Wolfgang Meletzky – designer and founder of high-end reference components.

Stromtank – “made in Germany” – was developed in our Berlin factory. The tank is manufactured and assembled with noble and handpicked components.
