Stromtank

Normal household items create electrical interference that changes audio quality, and even the best power conditioners cannot eliminate all disturbances. The Stromtank solves these problems by taking your stereo off the grid – their products essentially encase a high-powered battery pack with an integrated pure-sine wave converter power supply. With Stromtank, your stereo system is totally disconnected from the grid, so you can enjoy clean undisturbed grid power, and achieve the ultimate fidelity in music playback.
