Stromtank S 2500 Battery Powered Generator

Audiophiles are always looking for clean, undisturbed grid power to achieve the next level of music quality with their Hi-Fi systems. One of the most important factors in hearing the excellent quality of your audio components is the purity and stability of the grid signal. Normal household items, like computers or microwaves, can influence the grid. Electrical interference changes audio quality, and even the best power conditioners cannot eliminate all disturbances.

The Stromtank S 2500 is a high-power battery pack with an integrated pure-sine wave converter power supply. Your audio system is totally powered by clean, dedicated battery power. With Stromtank S 2500, you can enjoy up to 4 hours of listening to music, then it automatically connects to the grid without interruption, to recharge the battery.

During the recharging process, you can listen without 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-/video-setup. Premium home theater equipment will also improve both visually and sonically with the Stromtank.
