STROMTANK is our radical solution to create an independent, stable power grid for your audio components. Models include the S-1000, S-2500 Quantum MK-II, and S-5000 High-Power; each has a powerful generator and battery with a unique feature. Modes: ON-grid to supply according to a regenerator principle, plus a boost function; and OFF-grid for 4-8 hours autonomy. When the battery level is low, it recharges from the mains.
