Stromtank? It’s an uninterruptible power supply for audio components from Winbat Technology
Effectively, a high power battery pack with integrated pure-sine wave converter. The Stromtank disconnects audio systems from the grid.
The Stromtank S5000 has a storage capacity of 5.000Wh and is contained in lithium-iron-phosphate-cells. These LiFe-PO4 cells are, say the company, “…intrinsically safe, environmentally friendly, very cycle-resistant and lightweight.”
It is possible to listen to music up to eight hours before the recharging processes start. Price is $30,000.
