STROMTANK S-1000 & S-2500 Quantum

MJ13.09.2020

Power conditioners

Stromtank has been conceived to become an ultimate solution to clean power supply. It operates with no dependency on power grid quality, providing the purest possible voltage to electronics. It proves once again – and it does so in a rather unrivaled way – that it is the power foundation that lifts up the good systems to the great ones.

The Stromtank delivers the clean voltage from a battery pack that resides inside the unit and makes it rather heavy (from 40kg to 125kg depending on the model). I had two Stromtanks available for the review - the S-1000 and the S-2500 Quantum – that share similar design principles and aesthetics.

The large analogue Amper-meter is arguably the most attractive visual feature of the Stromtank. Although it takes strong resemblance to D’Agostino meters or Chord’s Dave display, Stromtank refrained from adding all the gold and copper accents that make D’Agostino amps look so Asian, and stuck to a cleaner industrial layout.

Depending on the Stromtank’s running mode the meter is either backlit in green (off-the-grid battery operation) or in blue (the outputs of the Stromtank are connected to the AC grid, the batteries only used as a buffer). Correspondingly the meter shows either discharge current of batteries (green mode) or battery charging current (blue mode). If one needs to know what the voltage draw from the Stromtank is in Watts, then just use the average battery voltage of 26,4V and multiply the meter’s reading with it. 10A on the meter translate into 264W of power consumption, for instance.

The power pack inside the Stromtank comprises LiFePo4 battery cells, the technology that is the heart of Tesla Model 3 cars and which is responsible for most of the Stromtank’s mass. The batteries in the S-1000 should provide over 2 hours of energy in the off-grid mode, over 6 hours in S-2500 respectively. These calculations are based on the average power consumption of average electronics. In real use, when I only used the front-end components (digital sources) connected to the Stromtank S-1000 the battery capacity dropped to 20% after circa 20 hours, in case of the S-2500 Quantum it was more than 48 hours. The available capacity is indicated by a 10 segment LED bar under the Amper-meter. If the battery discharge reaches 10% (only one LED indicator is on) the Stromtank automatically switches to the recharging mode (blue). While recharging you can continue listening to music as usual. Well, not quite, because you will sorely miss the purity of sound of the off-grid mode.
